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.

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.

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.

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:
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.

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.
