As a result of insufficient neuromuscular adaptation, dynamic lower extremity alignment is exposed to biomechanical deficits in loading tasks. Regarding this issue, in designing injury prevention programs in addition to neuromuscular retraining and decreasing risk of injuries, sport performance indices are considered to gain more acceptance. This randomized controlled trial aimed to investigate the effect of 10-week soccer-specific functional training (SSFT) on the base of functional capacity concept on risk factors of lower extremity injuries and sport performance indices concurrently.
Twenty-seven young male soccer players (14–16 years) with a functional movement screen score of at least 14 (FMS score≥14) were randomly allocated into a control group (CG, n=13) and experimental group (EG, n=14). The CG continued only their regular soccer training. For EG, 3 sessions of SSFT (90 minutes per session) were weekly introduced in their soccer training for 10-week on the weight room facilities and soccer fields. The overall time weas assigned to training was the same in both groups. SSFT included strength, balance, core, plyometrics, speed and agility exercises as well as the soccer-specific drills. Measurements consisted of the Landing Error Scoring System (LESS), general and sport-specific performance tests include sprint, agility, power, balance, strength, best and average time of Shuttle-sprint and Dribble Test (SDT). ANCOVA was used for statistical analysis (P<0.05).
From the pre-test to post-test, EG compared to CG decreased significantly LESS score and time in the 30-m test, Arrowhead test and average SDT (P<0.001). Similarly, the improvement amount for the countermovement-jump test, YBT-LQ, and 1RM tests were significantly greater (P<0.001) in EG than in CG. The best SDT time didn't affect significantly (P>0.05).
This study showed that SSFT in combination with regular soccer training designed based on similarity and context principle of exercises reduced some risk factors of lower extremity injuries and induced sport performance improvements in young male soccer players.
