The main goal of military physical training is balancing the need to improve and maintain a high fitness level whilst minimizing injury risk. Injury risk increase is dependent on inter alia movement quality. The study group was composed of 54 soldiers with an average age of 34,7 ± 6,33 who served in the Polish Army Land Forces. The purpose of this study was to determine if body composition data, Functional Movement Screen results as well as fitness test results confirm their practical application for evaluation of physical condition of soldiers and their predisposition to injury. Furthermore, based on gathered data, we attempted to verify if there was a correlation between body composition or Functional Movement Screen scores and physical efficiency. The average distance for the Yo-Yo test was 827,4 m. The average FMS score was 14,6±2,24. The FMS scores ranged from 10 to 19 points. Based on received FMS results, soldiers were divided into 3 groups. Group I (n-17) comprised of soldiers who received less than 14 points on a 21-point scale. Group II (n-26) comprised of soldiers who received between 14 and 16 points, and group III (n-11) included subjects who scored above 17 points. Based on the obtained results, we conclude that the body composition analyser will be more useful for a quick, initial assessment of exercise capacity than results of the Functional Movement Screen. Examination using the body composition analyser provides data correlating with the exertion capacity of subjects and is less time consuming.
