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.

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.

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.
