Abstract Introduction. Since the competition period has been prolonged in modern football, it is important to know if a shortened preparatory phase is enough to improve motor fitness preparation. This study analysed the changes in the level of physical fitness in second-league soccer players with respect to training conducted during the preparatory period. Material and methods. Speed (5-m and 30-m sprint), endurance (progressive test), and power (Counter Movement Jump) were tested in 21 players at the beginning and at the end of the preparatory phase. Results. The results obtained indicate a significant improvement in physical capacity parameters as well as speed and strength abilities measured using 5-m and 30-m running speed tests and the CMJ test for muscle power. In the progressive test measuring anaerobic threshold speed, the players active in the central section of the pitch (centre-backs and central midfielders) achieved the best results, while in the speed trials and explosive strength trials, side-backs and side midfielders achieved the best results. Conclusions. During the winter preparatory season, the most significant changes in the physical fitness of soccer players were observed in aerobic endurance expressed as threshold speed (an increase of 1.2 km/h) and running speed measured as the time needed to cover a distance of 5 m (time reduced by 0.04 s) and 30 m (time reduced by 0.07 s). These traits are crucial in the preparation of soccer players for league matches and have the greatest impact on their performance in sports competitions.

Searching for potential relations between changes in 25(OH)D concentration and in physical fitness is an interesting scientific topic. Thus, the main purpose of this study was to investigate the changes in serum concentrations of 25(OH)D in young football players in conjunction with indicators determining bone resorption and physical fitness. A total of 35 young soccer players were tested during the autumn competition period. Biochemical analysis of blood, aerobic capacity, running speed and power tests (Wingate test, squat jump, counter movement jump) were carried out at the beginning and at the end of the competition period. Significant decrements in concentration of 25(OH)D from 33.9 ± 5.87 to 23.7 ± 5.58 ng/mL were noted after the analyzed competition period. There were no significant changes in aerobic capacity along the competition period. Significant improvements were observed in 10 m sprint, 30 m sprint (p < 0.001), maximal power (p = 0.011) and total work capacity (p = 0.024). We found that the effect of changes in the players’ physical fitness does not occur in relation to 25 OH(D) concentration but occurs when these changes are analyzed as a function of the duration of the observation period. Changes in physical fitness of soccer players are determined by other factors then 25(OH)D concentration.

Abstract The purpose of the study was to examine how various playing positions affected the number of (and percentage breakdowns for) physical and technical activities of soccer players in the Germany’s Bundesliga. A further objective was to identify and present features distinguishing between the activities of players within the Defender, Midfielder and Forward formations. The study sample comprised 4426 individual match observations of 473 soccer players competing in the Bundesliga during the 2016/2017 domestic season. Data from the Impire AG motion analysis system, and the so-called ”heat maps” it supplies, revealed areas in which players spent most time during a match, with 22 different playing positions on the pitch identified in consequence. Players in the formation comprising Defenders did not differ significantly in relation to the number of accelerations, the number of shots or the percentage of duels won. Furthermore, there were no significant differences among Midfielders in regard to total distance covered, mean running speed, the number of accelerations, the number of duels and the percentage of duels won. Likewise, Forwards did not differ in distances covered at ≥24 km/h, average running speed, the number of sprints, the number of shots, the proportion of on-target passes, the number of duels, or the percentage share of duels won. Irrespective of the formation or position on the pitch, today’s game of soccer also pays great importance to the number of accelerations, as well as the number of duels engaged in, and their effectiveness.

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.

Objectives: Soccer is amongst the most popular sports in the world, and also it is one of the sports in which physical injury occurs most. The aim of the present study was to investigate soccer players’ pre- and post-season physical injury-related parameters, to analyze the effectiveness of the training program, and to evaluate changes in their physical performance throughout the season. Methods: In the present study, 16 soccer players (mean age: 18.87±0.61 years) and 16 sedentary individuals (mean age: 20.93±4.48 years) were recruited. In both groups, proprioception, functional endurance, and coordination were assessed. Soccer players were assessed twice: pre- and post-season, while the sedentary group was assessed only once. Results: Pre-season concentric and eccentric coordination levels of the soccer players were found to be higher than those of the sedentary group (p<0.05). In addition, post-season concentric coordination levels of the soccer players were higher than those of the sedentary group (p<0.05). In terms of proprioception levels, no statistical difference was observed between pre- and post-season in the soccer group and between groups (p>0.05). When the pre-season values were compared with the post-season values in the soccer group, while there was a significant decrease in concentric coordination values (p<0.05). There was a significant increase in concentric endurance values (p<0.05). Conclusion: Pre- and post-season detailed evaluations of the soccer players would be beneficial in terms of not only identifying their physical needs and the shortcomings in their physical fitness but also they would be beneficial in designing the training programs.

 Abstract: The aim of the study was to compare the players characteristics and physical fitness parameters according to playing positions and to identify the relation between body composition and physical fitness in professional soccer players at the beginning of the preparation period. Sixteen professional soccer players participated in this study. Body composition was evaluated by air displacement plethysmography instrumentation (BOD POD®) and physical fitness with specific tests: Running Anaerobic Sprint Test (RAST), Counter Moviment Jump (CMJ), Squat Jump (SJ) and Abalakov jump (ABK), Yo-yo Intermittent Recovery Level 1 (Yo-yo IR1), agility test and flexibility. Kruskal Wallis test demonstrated no significant difference in all estimated body composition, age, height and physical fitness parameters according to three playing positions (p < 0.05). We verified a significant negative correlation between body fat percentage and the performance of CMJ, SJ, ABK, peak, mean and minimum power (-.51 to -.87) and a significant positive correlation with the agility parameter (r = .85). Regarding to lean mass percentage, a significant positive correlation was found with performance of CMJ, SJ, ABK and peak, mean and minimum power (.51 to -.82) and significant negative correlation with agility parameter (r = -.85). Based on the results, we concluded that at the beginning of a pre-season a higher body fat percentage is associated with a negative influence in physical fitness, thus confirming that a greater amount of lean mass percentage is positively associated with the initial level of physical fitness of professional soccer players. Resumén: El objetivo del studio fue comparar las características de los jugadores y los parâmetros de aptitud física según las posiciones de juego e identificar la relación entre la composición corporal y la aptitud física em futebolistas profisionales al inicio del período de preparación. Dieciséis futebolistas profesionales participaron em este estudio. La composición corporal se evaluómediante instrumentación de plestimografia por desplazamiento de aire (BOD POD®) y aptitud física com pruebas específicas: capacidade anaeróbia (RAST), saltos verticales (CMJ, SJ y salto abalakov- ABK), resistência aeróbia, prueba de agilidade y flexibilidad. Kruskal Wallis no demostró diferencias significativas em todos los parâmetros estimados de composición corporal, edad, altura y condición física según las três posiciones de juego (p < 0.05). Verificamos uma correlación negativa significativa entre el porcentaje de grasa corporal y el rendimento de CMJ, SJ, ABK, potencia pico, media y mínima (-.51 to -.87) y uma correlación positiva significativa com el parâmetro de agilidade (r = .85). Em cuanto al porcentaje de massa magra, se encontro uma correlación positiva significativa com el rendimento de CMJ, SJ, ABK y potencia pico, media y mínima (.51 to -.82) y correlación negativa significativa com el parâmetro de agilidade (r = -.85). Com base em los resultados, concluimos que al inicio de una pré-temporada um mayor porcentaje de grassa corporal se associa com uma influencia negativa em la aptitud física, confirmando así que uma mayor porcentaje de massa magra se associa positivamente com el nível inicial de aptitud física de los futebolistas profesionales.
