NCT03251404

Brief Summary

This study evaluates the effects of two different injury prevention exercise programs on sports-relevant performance tests and neuromuscular function in youth football players. Half of participants will receive education on an existing and previously tested exercise program, while the other half will receive education on a newly developed exercise program.

Study Arms (2)

Knee Control original

ACTIVE COMPARATOR

The Knee Control program exercise program will be performed during the warm-up to each football practice (at least twice per week) during the 12 week intervention period.

Other: Injury prevention exercise programs

Knee Control+

EXPERIMENTAL

The Knee Control+ is an extension of the original Knee Control exercise program offering a wider selection of exercises (to increase adherence) and more physically challenging exercises (adapted for athletes in the late teens and provide further stimuli to increase player performance and neuromuscular function). The program will be performed during the warm-up to each football practice (at least twice per week) during the 12 week intervention period.

Other: Injury prevention exercise programs

Interventions

Injury prevention exercise programsOTHER

The two intervention programs contain exercises aiming to increase lower extremity strength, core stability, balance and neuromuscular function.
