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).

The aim of the study was, among other things, to characterise the maximum distance run by the four best teams in the FIFA World Cup in Brazil, including individual tactical formations and players who played for at least 90 minutes in the whole tournament. In total, the highest results of 68 players were established. In the analysis data obtained using Castrol Performance Index method were used. The mean maximum distance run by players of the tournament semi-finalist teams in the 24 analysed games was 11.63 km. The mean by the analysed defenders was 11.75 km, whereas for midfielders it was 12.02 km, for forwards – 11.02 km, and for goalkeepers – 5.65 km. In group of all 68 respondents soccer players a distance of over 15 km in one game was obtained by Bastian Schweinsteiger, Thomas Müller and Lucas Biglia.

In comprehensive preparation of a player to football competition special attention is paid to his predispositions in terms of speed abilities. Therefore, the authors’ objective was to analyse maximum locomotor speed of players of the four best national teams competing during the FIFA World Cup in Brazil, including specifying the differences in terms of speeds of these national teams and players in corresponding playing positions of individual teams. The analysis used data obtained using the Castrol Performance Index, a kinematic method and in order to present significance of differences between the studied teams and playing positions one-way analysis of variance (ANOVA) was performed. The study showed that the mean maximum running speed of the players of the four best teams of the World Cup was 8.34 metres/ second. The mean maximum locomotive speed of the defenders in semi-finalist teams of the tournament was 8.29 m/s, while the midfielders’ speed was – 8.16 m/s, the forwards’ – 8.48 m/s and the goalkeepers’ – 7.40 m/s. The players who had a maximum speed of 9 m/s or more were the Dutchman Ron Vlaar (9.16 m/s) and the Argentines José María Basanta (9.09 m/s) and Ángel Di Maria (9.17 m/s). There is no significant difference between the world’s best teams, including between their corresponding playing positions, in the level of maximum running speeds determining the dynamics of the game.

Despite many previous studies dealing with various aspects of physical activity in individuals with an amputation, the risk of injury in amputee footballers has not been assessed thus far. The aim of this study was to characterize the incidence and causes of sport injuries experienced by amputee football players. Furthermore, the incidence of injuries was stratified according to the players’ level of competitive aggressiveness and anger, and their role in the field. The study included 21 members of the Polish National Amputee Football Team, who have been followed-up for a period of 6 months. A total of 16 injuries were recorded, including three that required a medical consultation: luxation of the left elbow, adductor strain and ankle sprain. The group of injuries that have not been consulted with a physician included muscle strains (n = 4), abrasions (n = 3), bruising (n = 3), joint subluxations (n = 2) and luxation (n = 1). The injuries turned out to be more frequent in the lower limbs (n = 10) than in the upper ones (n = 6). The risk of injury turned out to be higher during trainings (n = 9) than matches (n = 7). Amputee football seems to be associated with low risk of injury, since only several bodily contusions were documented throughout the study period. The injuries occurred in 38% of the players; this makes amputee football a relatively safe discipline which can be recommended to physically disabled persons.
