Injury Prediction Study Using Functional Movement Screen (FMS) in Adolescent Racket Sports Enthusiasts

This study utilized the Functional Movement Screen (FMS) to assess the athletic ability of adolescent racket sport athletes and explored its association with injury risk. The results indicate that shoulder mobility (2.58 ± 0.57) and active straight leg raise (2.38 ± 0.74) scored the highest, while deep squat (2.08 ± 0.83), in-line lunge (1.98 ± 0.75), and rotary stability (1.62 ± 0.49) were comparatively lower. The ROC curve analysis yielded an AUC of 0.779 (95% CI: 0.639-0.919, P < 0.001), suggesting a significant predictive value for injury risk. Athletes scoring ≤ 15 points on the FMS exhibited a higher risk of injury, with a relative risk (RR) of 1.58. The findings emphasize the importance of core strength and lower limb stability training, along with optimized warm-ups and technical guidance, to reduce injury risks among young athletes. These insights offer theoretical support for future training and rehabilitation strategies.
