The '11' exercise program resulted in no difference in performance test changes compared to a control group after a 10-week training period in adolescent female football players.
RCT (n=34)
Randomly assigned
The injury rate in football is high, and effective injury prevention methods are needed. An exercise program, the "11," has been designed to prevent the most common injury types in football. However, the effect of such a program on performance is not known. The aim of this randomized-controlled trial was to investigate the effect of the "11" on performance after a 10-week training period. Thirty-four adolescent female football players were randomly assigned to either an intervention (n=18) or a control group (n=16). The "11" is a 15-min program consisting of ten exercises for core stability, lower extremity strength, balance and agility. Performance tests included isokinetic and isometric strength protocols for the quadriceps and hamstrings, isometric hip adduction and abduction strength, vertical jump tests, sprint running and soccer skill tests. There was no difference between the intervention and control groups in the change in performance from the pre- to post-test for any of the tests used. In conclusion, no effect was observed on a series of performance tests in a group of adolescent female football players using the "11" as a structured warm-up program.
Steffen et al. (Fri,) conducted a rct in Healthy adolescent female football players (n=34). The '11' exercise program vs. Control group was evaluated on Change in performance from pre- to post-test (strength, jump, sprint, and soccer skill tests). The '11' exercise program resulted in no difference in performance test changes compared to a control group after a 10-week training period in adolescent female football players.
