This chapter provides the historical background of the Sportsmetrics ACL intervention training program, which was the first ACL ligament intervention program for female athletes to be published in the peer-reviewed orthopedic literature. The program focuses on decreasing landing forces and improving lower limb alignment from a valgus position to a neutral position by teaching neuromuscular control of the lower limb and increasing knee and hip flexion angles. The dynamic warm-up, plyometric jump training, strengthening, and flexibility components are described and illustrated in detail. The results of numerous research investigations documenting improvements in neuromuscular indices and ACL injury rates are provided.
