Plyometric Training With or Without Hamstring Strengthening for Preventing ACL Injuries in Female Amateur Athletes

This randomized controlled trial explored the effect of plyometric training with or without hamstring strengthening in preventing anterior cruciate ligament (ACL) injuries among female amateur athletes aged 18 to 30. Sixty participants were divided equally into two groups: one received plyometric training combined with hamstring strengthening, and the other received plyometric training only. Both groups trained twice per week over a six-week period. Outcomes measured included knee strength (flexion and extension), dynamic balance (Star Excursion Test), and functional mobility (KOOS).
