    Opis:
    The goal of the present study was to investigate the effect of competition on brain activity representing aggression. Quantitative electroencephalograms (QEEGs) of Thai professional female soccer team players were analyzed in terms of aggression. The QEEGs of 17 soccer players were recorded three times: twice before a competition (once per week) and one week after the competition. There was a significant increase in the beta frequency band associated with the Fp1, Fp2, F7, and F8 positions as the competition approached. The changes in brain activity were observed in two patterns: the first was an increase in the intensity level of brain processing (presented in terms of brain topographic maps as absolute power), and the second was the magnitude of the amplitude at each of the EEG channels between the hemispheres (presented in terms of brain connectivity as amplitude asymmetry). Consequently, QEEG values were examined as they related to aggression. In the statistical analysis, paired-sample t tests confirmed that an aggressive phenomenon occurred as the competition approached. In addition, the aggressive phenomenon was found in the brain activity of players with defensive soccer positions.

    Opis:
    Purpose: The purpose of the study was to assess the symmetry of proprioceptive sense among female soccer players when trying to reproduce isometric knee extensions (right and left) and to analyze the impact of a given level of muscle force on proprioception. Methods: The study involved 12 soccer players aged 19.5 ± 2.65 years. Soccer players performed a control measurement of a maximum 3s (knee at the 90°) position in the joint. Subsequently, 70%, 50%, and 30% of the maximum voluntary contraction (MVC) were all calculated and then reproduced by each subject with feedback. Next, the players reproduced the predefined muscle contraction values in three sequences: A – 50%, 70%, 30%; B – 50%, 30%, 70%; C – 70%, 30%, 50% of MVC without visual control. Results: In every sequence, the participants found obtaining the value of 30% of MVC the most difficult. The value they reproduced most accurately was 70% of MVC. Both trial II and trial III demonstrated that the symmetry index SI significantly differed from values considered acceptable (SIRa). In each successive sequence the largest asymmetry occurred while reproducing the lowest values of MVC (30%) (p < 0.05). Conclusion: High level of prioprioceptive sense is important to soccer players due to the extensive overload associated with dynamics stops or changes in direction while running. Special attention should be paid to develop skills in sensing force of varying levels. It was much harder to reproduce the predefined values if there was no feedback.

    Opis:
    The main goal of the present study was to examine muscle strength and power of dominant and non-dominant leg, knee extensors and flexors, and their correlations with jumping performances in soccer players. A secondary aim was to evaluate muscle sense. Methods: 31 male professional strikers (age 20.9 ± 2.3 years, body mass 75.1 ± 6.6 kg, body height 179.5 ± 4.7 cm) participated in the study. The power output of lower extremities and the height of rise of the body mass centre during vertical jumps were measured using a force plate. The maximum muscle torque of the flexors and extensors of the knee were measured under isometric conditions using a special isometric torquemeter. Force sense was measured in isometric conditions in two tests: (a) fifty percent of the maximal voluntary contraction was set as a value of target force and the participants were instructed to reproduce the target force, (b) the participants attempted to develop a torque reproducing a sine course within the range of 10 to 50% of MVC performed. Results: A direct relationship was observed between the peak muscle torque in knee extensors developed during isokinetic contraction at all velocities and power and height of three types of vertical jumps ( p < 0.05). No correlation was observed between jumping performance and muscle torque under isometric condition. No differences were found in strength and jumping abilities as well as in force sense between dominant and non-dominant legs. Conclusions: This study offered a comprehensive and complete evaluation of leg muscle strength, sense and power, with the use of using force plate and isokinetic dynamometry.

    Opis:
    High-intensity exercise increases reactive oxygen species formation, which in excess may cause oxidative stress. We assessed nutritional status and exercise-induced oxidative stress in 20 adolescent male soccer players (age: 15-17). Participants were divided into two teams for a 60-minute friendly match and evaluated immediately before (Pre-match), 30 minutes after (Post-match I) and 24 hours after (Post-match II) the game. All players recorded a 3-day dietary intake. Biochemical tests were performed for lipid profile, muscle damage (creatinine and creatinine kinase [CK]) and oxidative stress (thiobarbituric acid-reactive substances [TBARS], protein carbonyls [PC], reduced glutathione [GSH], and vitamins E, C, and A). CK and creatinine were significantly elevated at Post-match I (p < 0.01), returning to baseline at Post-match II. Vitamins E, C and A were significantly elevated at Post-match I (p < 0.01), but only vitamins E and A remained high at Post-match II. TBARS showed no significant changes. GSH showed a significant decrease (p < 0.01) and PC showed a slight but significant increase (p < 0.01) at Post-match II. The recruitment of non-enzymatic antioxidants prevented lipid peroxidation, but dietary and especially endogenous defence responses were insufficient to prevent protein oxidation. Proper nutrition is essential to improve the activity of the antioxidant defence system, preventing exercise-induced oxidative stress.

    Opis:
    Background: The most important element of a well-balanced diet is a proper energetic value. Energy deficiencies are often observed in athletes, especially women. Energy deficiencies can lead to low energy availability which can cause serious health problems and affect exercise capacities. There is, therefore, a risk of health complications and reduced physical performance among female soccer players. Objective: The aim of this study was to check the frequency of low energy availability appearance in a group of women training soccer, which could results in negative health effects due to Relative Energy Deficiency in Sport (RED-S). Material and methods: Thirty-one professional female soccer players practicing on different league levels (Extra-league, I league, II league) participated in the study. The participants had their height and body mass measured. To assess the Energy Intake the method of 3-day dietary food recording was used. Total Energy Expenditure (TEE) and Exercise Energy Expenditure (EEE) was measured by means of an Armband SenseWear Pro3 device. The content of fat free mass was assessed with Akern BIA 101 Anniversary Sport Edition device. Results: The body mass median of participants was 58 kg. The average height was 166±5 cm, and the average BMI was 21.4±2 kg/m2. TEE was 2703±392 kcal/day, while EEE was 515 kcal (203-597 kcal). Energy intake was 1548±452 kcal/day. Energy availability was 25±11 kcal/kg fat free mass/day. Twenty of the study participants had low energy availability. The percentage of EEE in TEE was 17.93±3.14%. Conclusions: Low energy availability was demonstrated in the vast majority of studied group, which may lead to negative health consequences or reduction of exercise capacity.
    Wprowadzenie: Najważniejszym elementem dobrze zbilansowanej diety jest jej odpowiednia wartość energetyczna. Niedobory energetyczne są często obserwowane wśród sportowców, zwłaszcza kobiet. Niedobory energii mogą prowadzić do wystąpienia niskiej dostępności energii, co może powodować poważne problemy zdrowotne i wpływać na zdolności wysiłkowe. Istnieje zatem ryzyko powikłań zdrowotnych i obniżonej sprawności fizycznej wśród kobiet-sportowców, w tym żeńskich zawodniczek piłki nożnej. Cel badań: Celem badań była ocena jaki odsetek kobiet trenujących piłkę nożną jest narażonych na negatywne skutki zdrowotne wynikające z niskiej dostępności energii oraz ryzyka wystąpienia syndromu względnego niedoboru energii w sporcie (RED-S). Materiał i metody: W badaniu wzięło udział 31 zawodniczek grających na trzech różnych poziomach ligowych (Ekstraliga, I liga, II liga). Zmierzono wysokość i masę ciała uczestniczek. Aby ocenić spożycie energii z dietą zastosowano metodę 3-dniowego bieżącego notowania. Całkowity wydatek energetyczny (TEE) i wydatek energetyczny w trakcie treningu (EEE) mierzono za pomocą opasek naramiennych SenseWear Pro3. Zawartość masy beztłuszczowej oceniono za pomocą urządzenia Akern BIA 101 Anniversary Sport Edition. Wyniki: Mediana masy ciała uczestniczek wyniosła 58 kg. Średnia wysokość ciała wynosiła 166 ± 5 cm, a średnie BMI 21,4 ± 2 kg/m2. TEE wynosił 2703 ± 392 kcal/dzień, podczas gdy EEE wynosił 515 kcal (203-597 kcal). Spożycie energii wyniosło 1548 ± 452 kcal / dobę. Dostępność energii wynosiła 25 ± 11 kcal / kg masy beztłuszczowej / dzień. Dwadzieścia uczestniczek badania miało niską dostępność energii. Procentowy udział EEE w TEE wynosił 17,93 ± 3,14%. Wnioski: Wykazano niską dostępność energii u zdecydowanej większości kobiet z badanej grupy, co może prowadzić do negatywnych konsekwencji zdrowotnych i/lub zmniejszenia zdolności wysiłkowych.

    Opis:
    Brain central fatigue has been hypothesized as a factor affecting sports performance that generally occurs after a competition. Therefore, the aim of this study was to observe brain activities after participating in a competition. This study used quantitative electroencephalography (QEEG) to evaluate brain central fatigue, and the results were analyzed in terms of brain connectivity (coherence) in the delta frequency bands. QEEGs were recorded from twenty-nine Thai professional female soccer players (mean age ± SD was 24.17 ± 2.633 years, mean height ± SD was 1.620 ± 5.552 meters, mean weight ± SD was 55.10 ± 5.853 kg). We recorded QEEG three times: twice before a competition (once a week) and one week after the competition. Data obtained were analyzed by using the Z-scored FFT method. The results of brain connectivity were represented in terms of coherence. The present study revealed brain central fatigue in athletes after the competition (p=.035 and p=.003). This condition could affect their performance during games. Moreover, the key players showed specific brain patterns that were significantly different from substitute players (p<.000). The brain commonly returns to a normal state after a competition. This phenomenon was observed in the substitute players. Contrastingly, key players (on the ground players) exhibited the brain central fatigue phenomenon. Our study confirmed that brain central fatigue can arise after a competition, and specific brain patterns can identify the level of sports performance. These findings are beneficial for predicting athletes’ performances in terms of aspects of the brain. This approach can be used to measure and interpret brain central fatigue conditions.

    Opis:
    An increase in the value of the hamstring-to-quadriceps (H/Q) ratio with an increase in angular velocity may effectively prevent injuries of the back of the thigh. Previous studies have found that the conventional H/Q ratio was unaltered along with an increasing angular velocity in females. Therefore, this study aimed to investigate the relationships between the conventional H/Q ratio and angular velocity in a group of female soccer players. Methods: The study was carried out on a group of 16 female soccer players (age: 20.7 ± 3.9 years, body height: 166.1 ± 5.8 cm, body mass: 58.4 ± 6.2 kg, training experience: 8.8 ± 4.1 years). Measurements of peak torque of extensors and flexors of the knee joint under static conditions and under isokinetic conditions (at angular velocities of 30°/s, 60°/s, 90°/s and 120°/s) were carried out using a Biodex dynamometer. Results: There was a statistically significant increase in the conventional H/Q ratio with an increase in angular velocity. These differences occurred between measurements at angular velocities of 0°/s and 30°/s, and 30°/s and 60°/s. Conclusions: As previously found for males, an increase in conventional H/Q ratio with increased angular velocity was also present in this group of female players. This phenomenon should reduce the number of injuries of the muscles of back of the thigh. Coaches should pay attention to increasing the level of strength in the group of knee joint flexor muscles so as to make the value of the H/Q ratio appropriately high and increasing with increasing angular velocity.

    The aim of this study was to evaluate the potential correlation between asymmetry of lower limb muscle torque, asymmetry of vertical ground reaction force during take-off in young soccer players and their jumping abilities. Methods: Twenty-three young soccer player (16.9 ± 0.64 years old) participated in measurements. An isokinetic dynamometer, the Biodex System, was applied to test muscle torque (PT) of the knee flexors and extensors. The vertical ground reaction force (vGRF) was recorded from two Kistler plates. Jumping abilities were assessed with the horizontal (HJ) and vertical jump (VJ) tests. The asymmetry index (AI) was used to assess the asymmetry of the limbs. Results: The asymmetry index showed the highest asymmetry (over 10%) for the PT under static conditions for knee flexors and extensors. The correlation (–0.432, p = 0.038) was found between the asymmetry of vGRF and the height of the VJ. There was no correlation between the muscle torque and the height of the vertical jump. However, a correlation between the HJ length and muscle torque for flexors and extensors of the right and left lower limb was found. Conclusions: The asymmetry of the muscle torque of the flexors and extensors of the knee joint does not correlate with the results of both jumping ability tests. There was a statistically significant correlation between the vGRF asymmetry index during take-off and the height of the VJ. In the HJ, such a relationship was not found.

    Background: Training of athletes for optimal performance would be enhanced in an environment of appropriate data. There is, however, limited data on anthropometric and sport performance characteristics of male soccer players in Ghanaian public universities. This study comparatively presents the distribution of anthropometric and motor performance characteristics of male soccer players among public universities. Methods: Male soccer players (n = 44, mean age = 22.61 ±1.87 yrs) from four public universities were recruited. Weight, leg length, thigh girth, calf girth, forearm length, upper arm length, upper arm girth, chest girth, and finger span were measured. The participants were also assessed on a 36.58 m (40 yards) dash, vertical jump, agility, flexibility, sit-ups, push-ups, dribbling, shooting accuracy, and kicking distance. Results: There were significant differences in the forearm length (p = 0.001), leg power (p = 0.040), abdominal strength (p = 0.005), agility (p = 0.001), flexibility (p = 0.009), and upper body strength (p = 0.023) among the male soccer players of the universities. All anthropometric characteristics significantly predicted kicking distance (p = 0.002). Thigh girth (p = 0.014), chest girth (p = 0.010) and finger span (p = 0.012) significantly distinctly served as predictors. Conclusion: Anthropometric and motor performance characteristics were relatively different among male soccer players in Ghana public universities. University soccer coaches should place major emphasis on individual traits and potentials when developing combined training regimes.

    Opis:
    The aim of this study was to examine the differences in body composition, strength and power of lower limbs, height of jump measured for the akimbo counter movement jumps, counter movement jump and spike jumps between deaf and hearing elite female soccer players. Methods: Twenty deaf (age: 23.7 ± 5.0 years, hearing loss: 96 ± 13.9 dB) and 25 hearing (age: 20.3 ± 3.8 years) participated in the study. Their WHR and BMI were calculated. Body fat was measured using the BIA method. The maximal power and height of jump were measured by force plate. Biodex dynamometer was used to evaluate isokinetic isometric strength of the hamstrings and quadriceps. Results: Significant differences between hearing and deaf soccer players in anthropometric values were for the waist and calf circumferences and the WHR index ( p < 0.01, effect size 0.24–0.79). Statistically significant differences were observed for flexion of the lower limb in the knee joint for the relative joint torque and relative power obtained for the angular velocity of 300 degˑs–1 for both lower limbs (p < 0.01, effect size 0.19–0.48) and for 180 degˑs–1 during flexion of the left limb (p = 0.02, effect size 0.13). The hearing female football players developed significantly greater MVC in all the cases. Statistically significant differences between deaf and hearing athletes were found for spike jump for maximal power (1828.6 ± 509.4 W and 2215.2 ± 464.5 W, respectively; p = 0.02, effect size 0.14). Conclusions: Hearing impairment does not limit the opportunities for development of physical fitness in the population of deaf women.

    Opis:
    Recently developed the agility and skill tests (AS) were reevaluated to assess the children’s agility together with the soccer shoots to ball for goal. Children (male) soccer players (N=68) (age= 11.6 ± 0.5 yrs; height=147 ± 6.6 cm; weight= 35.5 ± 5.6kg) participated in this study. Test – Retest and comparisons, including 20m Sprint, Long Jump, T- Drill Test, AS (with ball), AS (goal success) and Zigzag Tests were used to assess the children’s sprinting, jump power, and agility with shooting ball. All handled test results showed that there were significant differences between the tests - retest sessions (p < 0.01) except for the 20 m Sprint. There were a near perfect correlations between test and retest values (r=0.90-0.99). A higher level of correlation between the AS tests (goal success, with ball) (r=0.99) was found. There were very high levels of correlations between the AS (goal success and with ball) tests and Zigzag tests (r=0.71, r=0.70 respectively). These results suggest that the AS tests are reliable and valid agility and skill tests for children players. Because the AS tests have unique values and are composed of soccer specific agility and active shooting skills, they are very important in identifying the talent and ability of children.

    Opis:
    This study examined the effects of an on field combined strength/speed/soccer training program on the physical performance of 20 male adolescent (age: 14.0 ± 0.7 years) soccer players, who were divided into an experimental and a control group (EG, CG). The EG players wore "weight shorts", with 300 gr of additional weight on each thigh and participated 2 times/week in a 12-week training intervention program. The CG followed the same training program without wearing the "weight shorts". The physical abilities were evaluated the week before (pre) and two days after the 12-week intervention training period (post) and the follow-up evaluation was performed 4 weeks after the post measurement. The measured parameters were: a) sprint/repeated sprint ability (straight and with 180º turns, RSA-best/mean/total), b) RSA fatigue-index, c) vertical jump ability and d) lower body maximal strength. The EG improved significantly more (p< 0.05) compared to the CG on 10-m-straight, 30-, 35-, 40-m with 180º turns RSAbest-sprints, RSA fatigue-index, squat jump, leg curl (single right/left leg) and in split squat (single right/left leg) 5RM load. Using special shorts with additional weights on the thighs during soccer training improved speed/RSAbest-times and fatigue-index, jump ability and lower limbs maximal strength in youth soccer players.

    Opis:
    Functional Movement Screen (FMS) is a functional screen test of the motor system which is steadily gaining recognition and popularity among individuals interested in prevention of sports injuries. The FMS test battery includes seven mutually related motor activities to analyse the quality of basic movement patterns. An in-depth interpretation of the performed test design provides good conditions to determine the weakest links in the kinematic chain and to estimate the risk of injury. The objective of this study was to determine the effect of the FMS test results on frequency of sports injuries in soccer players. With the main objective of the study in mind the following research hypothesis was formulated: “a group of players in the lowest interval (14–17 FMS test points) will have a high frequency of injuries in comparison to a group in the upper interval (18–21 points in the FMS test)”. The tests were carried out on a group of 102 younger and older junior soccer players representing the Soccer Academy of KKS Lech Poznań. For that the test design with FMS test procedure was used, followed by a six month period in which the injuries of the individuals in the study group were recorded. The research hypothesis was not confirmed. In the analysis of the results no statistical significance was noted between the total number of points obtained in the FMS test and the number of injuries. It was noted that the number of injuries was statistically significantly correlated with the results of the Shoulder Mobility test of the right side (for all participants and for the players in the lower interval), Hurdle Step test of the left side (for a group of players in the lower interval), and the In-line Lunge test of the left side (for upper interval players). The results of the single variable logistic regression showed that injuries occurred more often in players of the lower interval. A forest plot indicates the direction of the increased risk of injury in players in the lower interval of points: OR = 1.14 (95% CL; 0.71 : 1.83).

    Opis:
    Proper planning of the training process based on individual LT and AT metabolic thresholds is essential to improve athletic performance. Development of endurance in soccer players is mainly based on continuous runs and variable-intensity runs, supplemented with strength conditioning and sport-specific training. The aim of the study was to analyse selected parameters of physical capacity of soccer players after 8-week variable-intensity running training and circuit training. The experiment was carried out in a group of 34 soccer players aged 21 to 26 years. The athletes were divided into two groups: 17 people in the experimental group and 17 people in the control group. The experimental group was involved in 30-minute tempo runs two times a week for 8 weeks with variable intensity at AT. In the same period, the control group performed two 60-minute continuous runs at the intensity of 70-75%HRmax. The determination of metabolic thresholds used two indirect tests: the multistage shuttle run test (beep test) and maximal lactate steady state test (MLSS) with author's own modification. In order to evaluate maximal heart rate (HRmax), the research procedure was started from the beep test (distance: 20 m). The speed at the first level was 8.5 km/h and increased with each level by 0.5 km/h. Training of the experimental group where variable exercise intensity was used caused a statistically significant increase in HRmax (by 1.9%) and blood lactate levels at the AT (by 20.5%). The training in the experimental group led to the statistically significant (p < 0.05) increase in the parameters of the following variables: HRmax (by 1.9%); lactate level (by 7.85); HR at the AT (by 1,9%); lactate level at the AT (by 20.5%). The assumptions of the experimental training did not cause statistically significant changes in pretest vs. posttest HRmax and blood lactate levels for the LT. Endurance training with high intensity is more effective in soccer players compared to training with moderate intensity. Development of special endurance in soccer should also assume the intensity and method of working similar to the method used during sport competition.

    Opis:
    Small-sided games (SSG) is one of the increasingly popular training method in developing fitness components and technical abilities among soccer players. The objective of this study was to investigate the effectiveness of SSG training towards player’s fitness components and technical abilities after six weeks of training program among youth soccer players. Sixty youth soccer players (M = 19.98 years of age; SD = 0.97) were recruited in this study and were divided into SSG intervention group (IG, N = 30) and control group (CG, N = 30). Agility, speed, cardiovascular endurance, passing and dribbling tests were conducted pre- and post- six weeks of training. Results showed that there was a statistically significant difference on speed, passing, dribbling and VO2max in the post-test among the IG group. When compared to CG, IG were shown to perform better at speed, dribbling and VO2max as it showed a significant difference between groups. As a conclusion, SSG training method can improve speed, passing, dribbling and VO2max. Therefore, this study recommends SSG training to be apply towards youth soccer players.

    Opis:
    Introduction: The aim of the study was to examine relationships between power of the lower limb and agility, speed, and change of direction (COD) deficit in professional female soccer players. Material and methods: Thirty-three elite Polish Extraliga league soccer players (aged 22 ±5 years; body height 166 ± 4 cm; body weight 58 ± 8 kg) performed the following fitness tests: lower limb muscle power (Leg Press, Half Squat, Counter Movement Jump), straight linear speed (SLS 20 m), and COD speed ( Zig-Zag test, COD deficit). Using the median value as a reference, the players were subdivided into two groups (n=17; n=16) according to their LP, HS 60% 1RM, CMJ (High values below median = stronger group and Low = weaker group ). Results: The COD deficit was calculated as the difference between the 20m speed and the Zig-Zag test. The stronger group was better than the weaker group in SLS 20m (p<0.05; ES=1.23; 0.83; 0.93), but in the Zig-Zag agility test, the difference in the results was not statistically significant (p>0.05; ES=0.48; 0.34; 0.34) and this affected the COD deficit, which was higher (p<0.05; ES=0.9; 0.73; 0.72). The most important finding was that the stronger group had a higher COD deficit and its improvement (reduction) occurs only if the results of the agility test are improved (through agility training) [Ydeficit All groups=0.10+0.87* 20m - 0.83* Zig-Zag]. Increasing power (HS, LP) lead to the improvement in SLS p<0.05, not to COD abilities. Conclusion: This can be useful for coaches during agility training and to improve COD deficit in soccer players and women in general.

    Background. The most important component of a well-balanced diet is the proper energetic value. However, adequate estimation of the body’s energy needs is difficult for professional athletes, including soccer players. There is little research showing energy expenditure during training and lack of studies on the energy expenditure of professional female soccer players during a match. Objective. The aim of our study was to estimate energy expenditure during training and official league match in female soccer players and comparing it. Material and methods. Seven Polish professionally practicing soccer females (23.4±6,6 years old; 63.5±7.8 kg; 168.5±5.8 cm; 46±4.4 kg fat-free mass) participated in the study. The participants had their height and body mass measured. Energy expenditure during activities was measured by means of a SenseWear Pro3 Armband device. Body composition was assessed with Akern BIA 101 Anniversary Sport Edition device. Results. Statistically higher energy expenditure was achieved in the study group during the match hour (452±55 kcal/ hour) compared to the training hour (353±28 kcal/ hour) as well as in the case of energy expenditure per hour of activity per kg of fat-free mass (match: 9.94±1.75 kcal/kg fat-free mass/hour; training: 7.71±0.8 kcal/kg fat-free mass/hour). During one hour of training, more time was spent on sedentary, light, and moderate activities, but the difference was statistically significant only for light activities. More time during the match hour than during the training hour was spent on vigorous and very vigorous activities. Conclusions. In conclusion, the energy expenditure of the players during the match was greater than in the case of the planned intensive training, which was caused by the timeshare of more intense physical activities and going a longer distance during match.
    Wprowadzenie. Najważniejszym elementem dobrze zbilansowanej diety jest jej odpowiednia wartość energetyczna. Jednakże odpowiednie oszacowanie potrzeb energetycznych zawodowych sportowców, w tym piłkarzy nożnych, jest niezwykle trudne. Niewiele jest badan wskazujących na wydatek energetyczny w trakcie treningu oraz brak jest badan wskazujących na wydatek energetyczny w trakcie meczu wśród piłkarek nożnych. Cel. Celem naszych badań było oszacowanie wydatku energetycznego w trakcie treningu i oficjalnego meczu piłkarskiego w grupie kobiet trenujących piłkę nożną oraz porównanie tych wartości. Materiał i metody. W badaniu wzięło udział siedem polskich profesjonalnych piłkarek nożnych (23,4±6,6 lat; 63,5±7.8 kg; 168,5±5,8 cm; 46±4,4 kg beztłuszczowej masy ciała) Zmierzono masę i wysokość ciała. Wydatek energetyczny w trakcie aktywności mierzono za pomocą opasek naramiennych SenseWear Pro3. Skład ciała oceniono przy użyciu analizatora Akern BIA 101 Anniversary Sport Edition. Wyniki. Statystycznie wyższy wydatek energetyczny obserwowany był w trakcie godziny meczowej (452±55 kcal/godzinę) w porównaniu do godziny treningowej (353±28 kcal/godzinę) podobnie jak miało to miejsce w przypadku wydatku energetycznego w trakcie godziny aktywności w przeliczeniu na beztłuszczową masę ciała (mecz: 9,94±1,75 kcal/ kg beztłuszczowej masy ciała/godzinę; trening: 7,71±0,8 kcal/kg beztłuszczowej masy ciała/godzinę). W trakcie godziny treningu więcej czasu poświęcone było na odpoczynek, aktywności lekkie i o umiarkowanym natężeniu, ale różnica była istotna statystycznie jedynie w przypadku aktywności lekkich. Więcej czasu w trakcie godziny meczowej, niż w przypadku godziny treningowej, było poświęcone na aktywności o wysokim i bardzo wysokim natężeniu. Wnioski. Wydatek energetyczny w trakcie meczu był wyższy niż podczas intensywnego treningu, co było skutkiem większej ilości czasu poświęconego na aktywności o wysokim natężeniu oraz dłuższe dystanse pokonywane w trakcie meczu.

    Opis:
    The purpose of this study was to evaluate the changes of speed, agility and power performance during one soccer season and the impact of functional fitness on changes in motor performance in elite female soccer players. This study was conducted with 18 members of the Polish Women's National Football Team. The analyzed training season was divided into four training phases. Physical performance was assessed by a test of quickness - the 5m sprint, tests of maximal speed - the 30 m sprint, test of agility L-run test and tests of lower limb explosive power - counter movement jump (CMJ) and counter movement jump with arm swing. Functional fitness was assessed using the Functional Movement Screen (FMS). Individual functional training as well as a training plan based on FIFA 11+ prevention were utilized. The analysis showed significant improvement in the CMJ test (F=3.02, p<0.05) and FMS score (F=5.959, p<0.01) during the in-season. Other parameters of physical performance were stable during the evaluation period. Positive correlations between baseline FMS score and changes of athletes' 30m sprint performance (r=-0.48, p<0.05), total in-season change of FMS score and total inseason change of 5m sprint performance (r=-0.53, p<0.05) were observed. Female soccer players during the in-season demonstrated a relatively good level of physical performance which corresponds to their particular training phase. Functional fitness intervention appears to be an effective way of improving speed, acceleration, and power performance in elite female soccer players.

    Opis:
    Background: Soccer players are injury prone, and increasing competition - especially at the highest level - leads to increasing training loads, and these may contribute to more injuries to players. Hence, the aim is to increase preventive measures and treatment in this field. Aim of the study: The paper examines soccer players’ susceptibility to injuries occurring at different levels of the sport’s development, and describes the accompanying conditions. Material and methods: The study involved 215 players of different levels, of which 105 came from the II and III league clubs (group I) and 110 from IV league clubs (group II ). The conducted research was based on a diagnostic survey using an anonymous questionnaire containing 15 questions developed by the authors. Results: Similar traumas (injuries) were observed among respondents of both groups. Group I had suffered injuries in the case of 92 (87.62%) respondents, while Group II contained 87 (79.09%) subjects who had suffered injuries. Group I trained harder than Group II , but the nature of the injuries was similar for all the players. The surveyed Group I had 100% access to physio-therapeutic help; in Group II this was the case for only 48 (43.64%) subjects. Group I also applied preventive anti-injury measures to a greater extent than Group II , in the form of pre-training warm-ups and post-training stretching and loosening. Conclusions: Among the more advanced soccer players there was a trend toward more traumas with similar kinds of sustained injuries, despite the greater availability of physiotherapy care and their use of more antiinjury prevention techniques than in the group representing the lower levels of sport advancement in soccer. This adverse effect is associated with the more intense training and training loads of the more advanced players.
    Wstęp: Piłka nożna jest sportem powodującym wiele kontuzji a wzrastająca rywalizacja – szczególnie na najwyższym poziomie – prowadzi do zwiększania obciążeń treningowych, które mogą się przyczyniać do powstawania większej ilości uszkodzeń ciała piłkarzy. Stąd dąży się do zwiększenia działań prewencyjnych i terapeutycznych w tym zakresie. Cel pracy: Zbadanie częstości pojawiania się kontuzji, przyczyn i skutków ich występowania oraz stosowanych sposobów prewencji urazów u piłkarzy nożnych o różnym poziomie zaawansowania sportowego. Materiał i metody: W badaniu wzięło udział 215 piłkarzy nożnych, z których 105 pochodziło z klubów II i III - -ligowych (grupa I), a 110 z klubów IV-ligowych (grupa II ). Przeprowadzono je w oparciu o metodę sondażu diagnostycznego z zastosowaniem anonimowego kwestionariusza ankiety własnego autorstwa zawierającej 15 pytań. Wyniki: W obydwu grupach zaobserwowano podobieństwa w zakresie odniesionej urazowości. W grupie I występowała ona u 92 (87,62%) ankietowanych, a w II grupie u 87 (79,09%) osób, przy czym grupa I trenowała intensywniej niż II , a charakter urazów był podobny u wszystkich piłkarzy. Badani grupy I mieli 100% dostępność do pomocy fizjoterapeutycznej, a w grupie II miało ją tylko 48 (43,64%) osób. Grupa I również w większym stopniu niż grupa II stosowała środki prewencji urazów w postaci rozgrzewki przed treningiem oraz rozciągania i rozluźniania mięśni po treningu. Wnioski: W grupie bardziej zaawansowanych piłkarzy nożnych występowała jedynie tendencja do większej urazowości przy podobnym rodzaju odniesionych uszkodzeń ciała, pomimo większej dostępności do pomocy fizjoterapeutycznej i stosowania przez nich w większym stopniu prewencji przeciwurazowej niż w grupie reprezentującej niższy poziom sportowy. To niekorzystne zjawisko związane jest z większymi obciążeniami treningowymi i startowymi bardziej zaawansowanych piłkarzy.

    Opis:
    The main purpose of this study was to determine the influence of different types of surfaces on the sprint test results. 33 male football players from two age categories - U15 and U18 - performed sprint tests (7 distances between 5 and 30m) and a 150m shuttle run test on three types of surfaces: natural grass [n], a synthetic surface [s] and a rubber surface [r]. The longer distance a player covers, the more likely it is that the importance of the type of running surface will be noticed. The rubber surface diminishes the negative effects of changeable factors on the reliability of the tests and therefore, in our opinion, is recommended for control tests and especially for longitudinal tests. Comparing the results of running speed tests performed on different surfaces and especially in different weather conditions is unjustified.

    Opis:
    Dietary nitrates have hemodynamic and metabolic effects on the body. This study aimed to investigate nitrate intake's effect on quadricep muscle oxygen saturation (StO2) of semi-professional soccer players during a repeated speed test (RSA). In a randomized, crossover design, 10 semi-professional soccer men players (21.3 ± 0.9yrs) performed two conditions: In one they consumed a nitrate-rich concentrated beetroot juice (250 mL/150 mg of NO3−) and in the other a placebo, 2h before a repeated sprint test. StO2 of the right vastus lateralis muscle was measured by near-infrared spectroscopy. A paired samples t-test was used to compute any differences in the subjects’ performance on the StO2 and on RSA test. The level of significance was set at p < 0.05. The supplementation of nitrates limited the decrease in muscle oxygenation during the six sprints of RSA test (p < 0.001) and also, there seemed to be a tendency for limited the decrement of performance on RSA test (t = -1.586, p = 0.157, η2 = 0.218). In conclusion, acute nitrate supplementation reduces the decrement of muscle oxygenation during exercise with repeated sprints and leads to a tendency of fatigue resistance during repeated sprints under controlled situations. Nitrate supplementation may have an ergogenic effect during exercise with repeated sprints via the higher muscle oxygenation.

    Opis:
    This study examined the effects of an alternative strength training method during soccer training on the development of physical and technical abilities of youth soccer players. 17 soccer players (age: 15±0.5 years) were divided in a control group (CG) and an experimental group (EG). The players of the EG wore a "weight shorts", with 300 gr of additional weight on each thigh, while they participated into 3 regular soccer training sessions per week, for 12 weeks. The CG followed the same training program without wearing the “weighted shorts”. Before and after 12 weeks of training, anthropometric characteristics, 10- and 30- m speed, the Arrowhead change-of-direction test, the Illinois agility test with ball, the countermovement jump, and the 5-repetition maximum (5RM) load at the split squat, leg extension and leg curl were measured. The EG improved significantly (p< 0.05) more in comparison with the CG in countermovement jump, leg extension and split squat (left leg) 5RM load. The addition of weights on the thighs using special shorts during soccer training sessions leads to increased jumping ability and lower limbs maximal strength in youth soccer players.

    Wstęp. Postawa ciała uwarunkowana jest napięciem odpowiednich grup mięśni, które decydują o określonym ułożeniu poszczególnych segmentów ciała człowieka. Coraz częściej wśród dzieci i młodzieży pojawiają się różnego rodzaju wady postawy ciała, które mogą być spowodowane czynnikami funkcjonalnymi. Jedną z przyczyn ich powstawania może być asymetria obciążeń, jaka często występuje w treningu specjalistycznym. Materiał i metody. Materiał badawczy stanowią wyniki pomiarów 24 piłkarzy nożnych w wieku 15 lat. Badania obejmowały ocenę postawy ciała, cechy antropometryczne oraz pomiary momentów sił prostowników i zginaczy stawu kolanowego. Pomiar statycznego momentu siły mięśniowej przeprowadzono na specjalnym stanowisku pomiarowym firmy OPIW. Do oceny postawy ciała wykorzystano sprzężony z komputerem posturometr S. Wyniki i wnioski. Kryterium oceny pomiaru kręgosłupa w płaszczyźnie czołowej była wartość kąta Cobba. Na tej podstawie stwierdzono występowanie skoliozy lub śladowej skoliozy lewostronnej u 29,3% badanych piłkarzy. W grupie ogółu badanych stwierdzono nieznaczną dominację prostowników i zgi- naczy prawej kończyny dolnej nad lewą. Ta sama tendencja występuje u osób bez skoliozy. U zawodników z bocznym skrzywieniem kręgosłupa dominują mięśnie prostujące i zginające staw kolanowy kończyny lewej. Ważnym kryterium oceny dozowanych obciążeń treningowych piłkarzy nożnych w obrębie prawej i lewej strony ciała może być badanie postawy ciała i momentów sił obydwu kończyn dolnych. Pozwoli to na ewentualne zniwelowanie nieprawidłowości w stosowanych metodach treningowych, które mogą być przyczyną problemów zdrowotnych sportowców.
    Introduction. Body posture is determined by muscular tone of the particular muscles that decide about the specific position of the human body segments. This feature is influenced by a tension of muscle groups, which determine the position of separate human body segments. Varius types of spinal abnormalities are caused by functional factors. Material and method. 24 soccer players in the age of 15 were examined. The study included body posture, anthropometric features, the force moments of knee joint flexors and extensors. The static measurements of the muscles’ force moment were evaluated on the special measurement post, made by OPIW Company. The body posture was assessed by means of computer aided posturometer S. Results and conclusions. The value of Cobb angle was the evaluation criterion for the spine measurement in the frontal plane. On that basis the scoliosis or the weak symptoms of left side scoliosis in 29,3% examined players were registered. A slight domination of the right lower limb extensors and flexors over left limb was observed in the research group. The same tendency is observed in the group without scoliosis. The opposite strength arrangement i.e. the domination of flexors and extensors bending left limb knee joint, was found in players with scoliosis. The examination of body posture and force moments of two limbs can be an important evaluation criterion of dosed training loads in soccer players within the area of both left and right body sections. It will help avoiding incorrectness in the applied methods, which may cause athletes’ health problems.

    Opis:
    Background. The popularity of soccer, including women’s soccer, continues to grow. The training of females requires the development of standards different from those in men’s soccer. Professionalization is necessary, including adequate mental preparation. Material and methods. A total of 35 female Polish national soccer players participated in the study. This study used Polish versions of two standardized questionnaires (DS14, SOC-29), and a questionnaire developed by the authors. The authors evaluated type D personalities and their correlations with psychological resources or the ability to manage them, i.e., with the sense of coherence. Results. The obtained results, when compared to the results of standardization studies, are at the average level. Moreover, the detailed analysis of negative emotionality (NE) and social inhibition (SI) indices allowed us to identify type D personalities in 7 (20%) out of 35 subjects. These individuals scored more than 10 points on each of these scales. Conclusions. The analyses have given rise to some alarming conclusions. One in five female Polish national soccer players has a type D personality. Female players with this diagnosis have a significantly lower sense of coherence. Moreover, it has been proven that there is a significant correlation between sense of coherence and the dimensions of type D personalities. These results suggest that interventions as well as educational measures to strengthen one’s psychological resources and improve one’s coping with difficult situations or stress should be taken.
    Wprowadzenie. Nieustająco wzrasta popularność piłki nożnej – również żeńskiej piłki nożnej. Szkolenie dziewcząt/kobiet wymaga opracowania standardów różnych od tych obowiązujących w męskiej piłce nożnej. Konieczna jest profesjonalizacja, uwzględniając również przygotowanie mentalne. Materiał i metody. W badaniu wzięło udział 35 zawodniczek, reprezentantek Polski w piłce nożnej. W badaniu wykorzystano polskie adaptacje dwóch standaryzowanych kwestionariuszy (DS14, SOC29) oraz autorski kwestionariusz ankiety. Analizowano osobowość typu D i jej związki z zasobami psychologicznymi czy umiejętnością zarządzania nimi, czyli z poczuciem koherencji. Wyniki. Uzyskane wyniki, w odniesieniu do wyników badań normalizacyjnych, są na poziomie wyników przeciętnych. Ponadto szczegółowa analiza wartości wskaźników negatywnej emocjonalności (NE) i hamowania społecznego (HS) pozwala zdiagnozować u 7 (20%) spośród 35 badanych osobowość typu D. Osoby te na każdej ze skal uzyskały wyniki powyżej 10 punktów. Wnioski. Analizy stały się podstawą sformułowania alarmujących wniosków. Co piąta reprezentantka Polski w piłce nożnej ma osobowość typu D. Zawodniczki z taką diagnozą mają istotnie niższe poczucie koherencji. Ponadto udowodniono, że istnieje istotny związek między poziomem poczucia koherencji a wymiarami osobowości typu D. Takie wyniki sugerują podjęcie działań interwencyjnych, a także edukacyjnych na rzecz wzmocnienia zasobów psychologicznych i doskonalenia procesu radzenia sobie z sytuacjami trudnymi lub stresem.

    Wstęp. Celem badań było poznanie poziomu sprawności motorycznej piłkarzy i ich umiejętność poruszania się w obrębie podstawowych wzorców ruchu; zidentyfikowanie najczęstszych dysfunkcji, asymetrii ruchu i ograniczeń funkcjonalnych. Materiał i metody. Łącznie przebadano 89 mężczyzn w wieku od 18 do 33 lat, podzielonych na grupę treningową (59 profesjonalnych piłkarzy) i grupę kontrolną (30 osób, które nie grały w piłkę nożną). Każdy uczestnik przeszedł jednorazowo badanie FMS obejmujące 7 testów ruchowych w oparciu o podstawowe wzorce ruchowe. Wyniki. Analiza statystyczna wyników wykazała, że średni wynik dla grupy badanej wynosi 15,3667, a dla grupy kontrolnej 11,9 punktów na 21 możliwych. Sprawdzano zależności pomiędzy wynikami testów FMS a: BMI (współczynnik korelacji Pearsona dla gr. 1 =0.9848 dla gr. 2= -0.31191), latami trenowania piłkę nożną (współ. korelacji Pearsona =0.21634) oraz liczbą kontuzji (współ. cząstkowy korelacji Pearsona = -0.13952). Wnioski. 1. Piłkarze uzyskali wyższe wyniki prawie we wszystkich testach oprócz jednego. 2. Prawidłowe BMI skutkuje lepszym wynikiem FMS. 3. Wraz ze wzrostem ilości lat zawodowego treningu oraz ilości przebytych kontuzji rośnie wynik końcowej oceny testów FMS. 4. Kończyna dominująca nie uzyskała lepszych wyników w testach asymetrycznych, urazy częściej występują w kończynie dolnej niedominującej, a w kończynie górnej dominującej.
    Background. The aim of our study was to explore soccer players’ motor fitness level and their ability to move within the basic movement patterns; identify most frequent dysfunctions, movement asymmetry, and functional limitations. Material and methods. A total of 89 males between 18 and 33 years of age divided into training group (59 professional soccer players) and control group (30 individuals who did not play soccer). Each participant underwent one FMS testing comprising 7 motion tests based on the basic motion patterns. Results. Statistical analysis revealed that an average result was for the training 15,4, and for the control group 11.9 out of 21 scores, respectively. The relationship between FMS testing scores, BMI (Pearson correlation coefficient group 1 = 0.9848 and group 2 = -0.31191), a number of years of training (Pearson correlation coefficient = 0.21634), and a number of injuries (Pearson correlation coefficient = -0.13952). Conclusions. 1. Soccer players obtained higher scores in all but one tests. 2. Correct BMI results in FMS testing. 3. Along with increase in a number of years of professional training and incurred injuries. 4. The dominant limb achieved no higher scores in asymmetry tests and injuries occurred in the non-dominant lower limb more frequently than in the dominant upper limb.

    Background. The aim of the study was evaluate the strength of the respiratory muscles, bite force, and occlusal force distribution of professional soccer players after training and detraining resulting from the lockdown that occurred during the coronavirus disease 2019 pandemic. Material and methods. Twelve male soccer players (age, 19-34 years) were subjected to respiratory muscle strength analysis by examining the maximal inspiratory and expiratory pressures, maximum molar bite force (right and left sides), and occlusal force distribution of the first permanent molars. Comparisons of variables after training and detraining were analyzed using the paired-sample t-test (p < 0.05), and the correlation between respiratory variables was measured using the Pearson test (p < 0.05). Results. There were no significant differences in the bite force and occlusal force distributions after training and detraining. The correlation results showed moderate positivity between the maximal inspiratory and expiratory pressures during the training period. Conclusions. The results suggest that when soccer players strengthen the inspiratory muscles, they also strengthen the expiratory muscles and that detraining does not impact the athlete's organic function, especially the respiratory muscle function and the forces of the occlusal contact of the first permanent molars.

    Opis:
    All professional athletes have to face is retirement from competitive sport at a younger age than most other individuals. Most non-athletes have a longer period and more established support systems that allow them to plan for their retirement than professional athletes whose retirement from professional sport can be precipitated without warning due to a number of factors which include age, deselection or injury. The purpose of this study was to investigate the influence of organizational support on retirement planning and financial management of professional soccer players. A quantitative research approach was used to collect data from a sample of professional soccer players in the Premier Soccer League in South Africa. The results of the study indicate that organizational support strongly influences retirement planning and financial management. Soccer clubs therefore need to have systems in place to assist professional soccer players to plan for their retirement.
    Wszyscy zawodowi sportowcy muszą stawić czoła emeryturze od sportu wyczynowego w młodszym wieku niż większość innych osób. Większość osób niebędących sportowcami ma dłuższy okres i bardziej określone systemy wsparcia, które pozwalają zaplanować emeryturę. Emerytura profesjonalnych sportowców może być przyspieszona bez ostrzeżenia ze względu na szereg czynników, do których należą: wiek, wycofanie zawodnika lub obrażenia. Celem niniejszej pracy było zbadanie wpływu wsparcia organizacyjnego w zakresie planowania emerytalnego i zarządzania finansami profesjonalnych piłkarzy. Ilościowe podejście badawcze zastosowano do zbierania danych z próby zawodowych piłkarzy Głównej Ligi Piłkarskiej w RPA. Wyniki badań wskazują, że wsparcie organizacyjne silnie wpływa planowanie emerytalne i zarządzanie finansami. Dlatego też kluby piłkarskie muszą mieć odpowiednie systemy pomocy, aby pomóc zaplanować emeryturę profesjonalnych piłkarzy.

Young male football players from Schools of Sports Masters in Oradea (Romania) and Łódź (Poland) participated in the study. During the training session the players participated in four small-sided games 6 vs. 6 with goalkeepers (4 × 4 min, 3 min of active recovery). Heart rate responses and distance covered during small-sided games were compared. There were significant differences in the distance covered by both nationality players and age groups in reference to each intensity zone. Polish players coverd significantly longer distance compared with romanian soccer players. The results of motion abilities of young players from two countries with different training systems show that training programs can have a significant effect on adoptive abilities of the players.

    Cel pracy. Analiza zależności pomiędzy poczuciem dyspozycyjnego optymizmu a częstością spożywania wybranych grup produktów spożywczych i środków ergogenicznych w grupie zawodników wyczynowo trenujących piłkę nożną. Materiał i metody. Badania przeprowadzono w grupie 203 piłkarzy nożnych w wieku 18–37 lat. Zastosowano autorski kwestionariusz częstości spożywania produktów i środków ergogenicznych oraz Test Orientacji Życiowej (LOT-R). Analizę wyników przeprowadzono z zastosowaniem współczynników korelacji rangowych Spearmana w pakiecie statystycznym PQStat ver. 1.6. Wyniki. Wykazano niedostateczną częstość konsumpcji produktów rekomendowanych, w tym: warzyw i owoców, produktów zbożowych razowych, mleka i produktów mlecznych, w tym fermentowanych, ryb morskich oraz olejów i orzechów. Analiza statystyczna wykazała dodatnią korelację pomiędzy poziomem dyspozycyjnego optymizmu a częstością konsumpcji: owoców (p<0,05), produktów zbożowych razowych (p<0,05), orzechów i migdałów (p<0,05) oraz wody mineralnej (p<0,001), a ujemną z częstością konsumpcji: jasnych produktów zbożowych (p<0,05), słodkich mlecznych produktów fermentowanych (p<0,01), słodyczy i wyrobów cukierniczych (p<0,05) oraz napojów energetyzujących (p<0,001). Spośród środków ergogenicznych zawodnicy okresowo sięgali po: witaminy i składniki mineralne, odżywki białkowe, napoje izotoniczne i kreatynę. Wykazano dodatnią korelację pomiędzy poziomem dyspozycyjnego optymizmu a częstością spożywania probiotyków (p<0,05). Wnioski. Wykazano zależności pomiędzy poziomem dyspozycyjnego optymizmu a częstością spożywania niektórych grup produktów spożywczych i środków ergogenicznych, ze wskazaniem na bardziej racjonalne wybory żywieniowe i częstsze stosowanie probiotyków wśród zawodników o wyższym nasileniu dyspozycyjnego optymizmu.

The aim of the study is to analyze relationships between the sense of dispositional optimism and frequency of consuming selected groups of food products and performance enhancers in professional soccer players. Material and methods. The study involved 203 soccer players aged 18–37. The tools used in the research were an original questionnaire to study the frequency of consuming products and performance enhancers, and the Life Orientation Test- Revised (LOT-R). The results were analyzed with the use of Spearman›s rank correlation coefficients in a statistical package PQStat ver. 1.6. Results. The study demonstrated insufficient consumption of recommended products, such as fruit and vegetables, whole grain cereal products, milk and milk products (including fermented), saltwater fish, oils and nuts. Statistical analysis showed a positive correlation between the level of dispositional optimism and the frequency of consumption of: fruit (p<0.05), whole grain cereal products (p<0.05), nuts and almonds (p<0.05) and mineral water (p<0.001), and a negative correlation in terms of consumption of white cereal products (p<0.05), sweet fermented milk products and confectionery (p<0.05), as well as energy drinks (p<0.001). Regarding performance enhancers, sportsmen periodically used vitamins and minerals, protein supplements, isotonic drinks, and creatine. There was a positive correlation between the level of dispositional optimism and the frequency of using probiotics (p<0.05). Conclusions. The level of optimism was found to be a predictor of the frequency of consumption of some groups of food products and performance enhancers. Sportsmen with higher levels of dispositional optimism displayed more rational dietary choices and more frequent use of probiotics.

    Opis:
    A particular meaning in contemporary soccer games is gained by the efficiency of actions in the situation of a 1 on 1 game. The application of an increased number of exercises based on small and supporting games in soccer training can help to increase the effectiveness of training in this aspect. The aim of the work was to determine the effectiveness of training for 11–13 year-old soccer players with the use of small and supporting games to improve actions during a one against one game. The tests were applied to a group of 11–13 year-old soccer players. We have conducted a pedagogical experiment, the fundamental element of which was to apply training based on small and supporting games in the experimental group, and then tracing the changes on the background of the comparative group. In order to diagnose differences in the effects of training, we have applied a set of test tasks (cycle of 1 × 1 simulation games, test of general physical fitness INKF). The applied training improved the actions in 1 × 1 simulation games. Throughout the experiment, the players from both teams presented a comparable level of the tested motor skills. The training based on small and supporting games seems to be an effective method of increasing training effectiveness in the context of action improvement in the situation of a 1 × 1 game.

    Objectives: The aim of this study was to compare the influence of creatine monohydrate and creatine malate supplementation on aerobic and anaerobic capacity in semi-professional soccer players during preparation period. Methods: 15 adult soccer players from polish second league club took part in the study. Participants were divided into two groups (Group 1: supplemented their diet with creatine monohydrate; group 2: used creatine malate). Before and after five-week preparations the aerobic (PWC 170 test) and anaerobic (Wingate test) capacity of the players were measured. Findings: Significant increase in PWC 170 indicator, maximal oxygen uptake, and total work capacity in Wingate test were noted in the group that consumed creatine monohydrate. Moreover, two-way ANOVA results showed significant effect for time in above mentioned variables. Conclusions: Creatine monohydrate supplementation may efficiently support aerobic and anaerobic capacity development in semi-professional soccer players. Five-week creatine malate supplementation provides no significant changes in aerobic and anaerobic capacity.

    The aim of the research was to determine whether there are any differences between the level of speed of reaction measured with the lower and the upper limb of the soccer players and the not-trained persons at different age. The research material consisted of 40 senior soccer players, born before year 1984 (older than 20) with over 11 years of training practice and 40 junior soccer players, age 13 with lass than 6 months of training practice. The comparing group consisted of 40 students of Elementary School no 37 in Szczecin, age 13 and 40 students of University of Szczecin, born before year 1984 (older than 20). All students did not do any kind of sports except the obligatory P.E. lessons at school and University. The research methods were the indirect tests of speed of reaction measured with the upper limb using the „catch of Ditrich’s stick” test and with the lower limb using the „stopping of the falling stick” test. The analysis of the research material allowed to formulate the following conclusions. There were no statistically significant differences in the results obtained with the lower and upper limb in the groups of both young and senior soccer players. Such as differences were however observed in the both comparing groups. The statistically significant differences were also noticed between the results of the speed of reaction obtained by the soccer players and the not-trained persons with both lower and upper limb. Senior sportsmen alike the young ones represented higher level of speed of reaction as their not-trained equals.

    Opis:
    The primary objective of this study is to conduct a comparative analysis of change of direction (COD) and agility among players engaged in soccer, basketball, and handball. Additionally, the researchers introduced the novel concept of “Agility deficit”, aimed at evaluating distinctions between COD and agility during running (COD-R; Agility-R) and dribbling (COD-D; Agility-D). The participant cohort comprises 38 individuals with an average age of 20.63 years, distributed across 13 handball players, 12 soccer players, and 13 basketball players. Statistical analyses, specifically ANOVA accompanied by Tukey’s post hoc comparisons, have been employed to discern significant differences among subgroups. While no noteworthy disparities among groups were observed in both COD-D and Agility-D when participants manipulated the balls using their hands, a marked superiority in performance emerged for soccer players when the balls were manipulated with their legs. Soccer players exhibited expedited responses compared to their basketball and handball counterparts when confronted with a visual stimulus during the Agility-R test (reduced Agility-R deficit). Furthermore, the Agility-D deficit underscored the heightened visual challenge to react in visual stimuli during dribbling in soccer. Independent of the type of ball handling, soccer players consistently demonstrated a diminished Agility-D deficit, affirming their superior visual ability. The performance in Agility-D further revealed that visual ability plays a pivotal role in influencing dribbling ability. The study posits that, for a comprehensive assessment of a player’s visual ability during running or dribbling, interpretations of both Agility-R deficit and Agility-D deficit are imperative. Consequently, the proposed indexes of Agility-R deficit and Agility-D deficit present valuable tools for evaluating players’ COD and Agility abilities during running or dibbling. However, the efficacy of these assessments in real-game situations remains undetermined, requiring further investigation.

    Polska piłka nożna po roku 1989 stanęła w obliczu rosnącego napływu piłkarzy zagranicznych. Rozwój gospodarczy kraju, poprawiające się warunki życia, ale także szersze inwestycje w sport powodują, że Polska staje się coraz atrakcyjniejszym miejscem dla wielu zawodników z całego świata. Autor artykułu skoncentrował się na zagadnieniu zatrudniania piłkarzy obcokrajowców w polskiej ekstraklasie piłkarskiej. Na podstawie danych statystycznych dokonał opisu zjawiska, zwracając uwagę zarówno na jego skalę i powszechność, jak też na regulacje ligowe, ograniczające napływ obcych piłkarzy, oraz sytuację młodych zawodników w kontekście tego zjawiska.
    Starting with 1989, Polish professional soccer has had to face a growing influx of foreign players. Economic development, improving living conditions, and wide–ranging investment in sport mean that Poland is becoming an increasingly attractive location for many professionals from throughout the world. The paper concentrates on the question of employing foreign soccer players in the top Polish league. Statistical data were used to describe the phenomenon, paying attention to both its scale and generality. It also looks at league rules, restrictions on the influx of foreign soccer players, and the situation of young people in the context of this phenomenon.

    Opis:
    The aim of this study was to assess the maximum velocity achieved by professional soccer players. The study involved 20 professional football players. The analysis of the achieved velocities during the season was based on individual maximum velocity values obtained in a preseason period test using the GPS monitoring device Catapult Vector S7. The study covered 20 match units and 77 training units. A velocity equal to or greater than 100% of the maximum velocity was achieved 24 times - 21 times (accounting for 88%) during a competitive match (MD 0), 1 time (accounting for 4%) two days before (MD-2), and two times (accounting for 8%) three days before (MD-3). A velocity in the range of 90-99% of the maximum velocity was achieved 207 times. The results confirm that football players can achieve values equal to or greater than 100% of their maximum velocities; however, this occurrence is rare. Due to the low probability of high maximum velocity values during a training microcycle, it is recommended to incorporate specific training methods that allow for achieving high maximum velocities to reduce the risk of hamstring muscle injuries among players, especially among reserve players (who rarely participate in competitive matches).

    Authors in their contribution deal with the issue of reactive and running agility in sport. Upon constructing the methods of research we assumed that players ́ performances in running agility (Illinois test) should increase with the age of soccer players. W e expected that we shall not prove this tendency in the level of reaction agility (FAC) with regard to the fact that performance in reaction agility is limited, besides motor, also by other prerequisites such as perception, state of receptors, sensoric and autonomous functions, spinal and supraspinal levels of motor system. We also expected that there will be no proved relationship between these tests ́ results in any age category. The level of performance in running and reactive agility increases with age; t he increase is smooth in running agility and cascaded in reactive agility starting with the 14 yrs. category. We also noted a downward tendency in the correlation between running and reactive agility with increasing age. This decline is most evident from t he 14 th year of age. The relationship between running and reaction agility was not observed in the study group from the age of 13. Coaches are recommended to switch over to the specific development of agility using the way of weakening anticipation ability of the player and to replace exercises with closed -loop skills by the ones of open -loop skills.

    The purpose of the study was to analyze the psychophysiological characteristics of football players and water sports athletes as factors of professional selection. Materials and methods: The study involved students of a specialized sports school (n = 31, age: 16-17 years). The participants were divided into two groups: group 1 - 20 football players, group 2 - 11 water sports athletes (swimming). The level of sportsmanship is 1 category, Candidates and Masters of Sports. Tests applied: determination of the duration of an individual minute (IM), measuring of a 10 cm segment (SM), determination of simple hand-eye coordination (SHEyC), and simple hand-ear coordination (SHEaC), the technique of “Figures memorizing”, solution of 10 sums. Results: The results of the IM test reflect the prevalence of the earlier test completion. All participants indicated a lower value in 9th test of a segment measuring. The results of the SHEyC and SHEaC of the participants were similar. The results of all tests were less than 10 in the test of “Figures memorizing”. Football players revealed link between coordination and psychophysiological tests results, while swimmers revealed link between coordination and sensory type of tests. Conclusions: The carried out psychophysiological analysis of athletes' condition of team sports and water sports confirmed the possibility of applying these tests for selection. The results obtained reflect the specific influence of the sport on the athletes' bodies. These indicators demonstrate the increased requirements for spatial orientation, the importance of reaction to auditory stimuli and the increased ability of football players to control the surrounding space and control the game situation.

    Opis:
    The aim of the present study was to examine how various playing positions and opponent team ranking affect the covered distances and the acceleration and decelerations profile of a team during 2018-19 Greek SuperLeague. StatSport GPS system recorded in match-play real-time both the players’ covered distances (m) and the number of acceleration/deceleration runs (n) in zones from 3 m/s2 to 10 m/s2. The descriptive statistics showed that the players’ mean covered distances were 10289 m per match. The MANOVA revealed significant differences of the players’ covered distances in all intensity zones in relation to their playing positions (F(12, 513.567)=41.862; p=0.000) and the opponent team ranking (F(3,189)=3.687; p=0.013). Furthermore, no significant interactions were observed between the playing positions and the opponent team ranking (F(12, 500.339)=1.149; p=0.318). Moreover, no significant differences were recorded regarding the opponent team ranking with the amount of accelerations (F(1,189)=0.501; p=0.480) and decelerations (F(1,189)=1.342; p=0.248). Summarizing, the current study showed the high-demanding competitive performance of midfielders, full backs and forwards regardless the standing of the opponent teams. Hence, the team’s training must include special stimuli of aerobic and high-intensity workouts according to the players’ playing positions in the match.

    Background. The current situation experienced by football clubs in the Hungarian women’s first division was analyzed. It was assumed that: one of the obstacles for the development is the presence of non-skilled sports experts (H1); all the foreign players achieve better results than the Hungarians (H2); and the foreign players are older than the Hungarians on average (H3). Material and methods. In this study, the qualifications of the coaches in women’s football were compared with those in the men’s first division. The number of games played, performance statistics and average age amongst the players were studied as well. The data was analyzed using crosstab and two sample T-tests. Results. H1 was confirmed by T-test and the significant result between the two groups was p=0.00. H2 was confirmed as well: the performance analysis was significant and the foreign players achieve better results (p=0.001). The Hungarian players have better results in terms of the number of games, the number of performances in the starting lineup and the number of seasons played in the first division. Conclusions. The examined problems in Hungarian women’s football have been proven. All the areas of women’s football considered in this study require development, especially in terms of the academic qualities of the coaches, which widely affect the team’ performance.
    Wprowadzenie. Przeanalizowano obecną sytuację, jakiej doświadczają kluby piłkarskie w węgierskiej pierwszej lidze kobiet. Założono, że jedną z przeszkód w rozwoju jest obecność niewykwalifikowanych ekspertów sportowych (H1), że wszystkie zagraniczne zawodniczki osiągają lepsze wyniki niż Węgierki (H2), a także, że zawodniczki zagraniczne są średnio starsze niż Węgierki (H3). Materiał i metody. W niniejszym badaniu porównano kwalifikacje trenerów w piłce nożnej kobiet z kwalifikacjami ich odpowiedników w pierwszej lidze męskiej. Przeanalizowano również liczbę rozegranych spotkań, statystykę występów i średnią wieku wśród zawodniczek. Dane analizowano za pomocą crosstab oraz T-testów do porównania obu grup. Wyniki. H1 potwierdzono T-testem, a wynik istotny pomiędzy obiema grupami wynosił p=0.00. H2 zostało również potwierdzone: analiza rozegranych spotkań dała istotny wynik, a zagraniczne zawodniczki osiągnęły lepsze wyniki (p=0.001). Węgierki uzyskały lepsze wyniki pod względem liczby rozegranych meczy, obecności w pierwszym składzie oraz liczby sezonów rozegranych w pierwszej lidze. Wnioski. Badane problemy w węgierskiej piłce nożnej kobiet zostały potwierdzone. Wszystkie przeanalizowane w niniejszym badaniu obszary piłki nożnej kobiet wymagają rozwoju, szczególnie w zakresie kwalifikacji naukowych trenerów, które w dużym stopniu wpływają na wyniki drużyn.
