RELATIONSHIP BETWEEN FUNCTIONAL LIMITATIONS OF THE LOCOMOTOR SYSTEM AND PERFORMANCE IN JUDO

Introduction. The high demands imposed by judo with regard to physical fitness can predispose athletes practising this sport to injury. The aim of the current study was to determine the relationship between the degree of functional limitations and performance outcomes in judo athletes. Material and methods. The study involved 23 judo athletes aged 17-27 years. For the purpose of carrying out comparative analyses, the judokas were divided into two groups according to their level of achievement. The first group consisted of medallists in international tournaments and Polish championships, and the second group was composed of non-medallists. The research tool used was the Functional Movement Screen test battery, which included seven exercise tests whose performance was rated on a scale from 0 to 3. Relationships between variables were assessed using Spearman’s rho correlation coefficients. Inter-group differences were determined by means of the Mann-Whitney U test, and differences between the left and right side of the body in bilateral tests were examined using the Wilcoxon test (statistical significance was set at p ≤ 0.05). Results. The total score for the FMS test was significantly higher (p < 0.05) in judo athletes who had a higher level of achievement. Scores below 14 points, which were indicative of high susceptibility to injury, were received by two athletes from the group of medallists and 8 non-medallists. Major asymmetries were not found in the subjects; significant differences were observed only in the shoulder mobility test in senior judokas (p < 0.05) and non-medallists (p < 0.01). Conclusions. Judo athletes who had better performance outcomes in competitions had higher scores in the FMS test. Functional limitations can have an impact on the outcomes of performance in judo; their degree is indicative of the quality of the movement as well as of susceptibility to injury.
