The training effect of lower limb alignment, knee flexion muscular strength, jump power and preventive effect of our practical training program in preventing anterior cruciate ligament injuries in female basketball players.

Our study aimed to investigate the effect of an anterior cruciate ligament injuries prevention program. Fifty-one female basketball players from high school participated in our study. Measurement was conducted before and after a 10-week prevention program. In alignment measurement, the distance between the hips, knees was measured during a drop-jump test, and the ratio of knee distance to hip distance (K/H ratio) was calculated. An isometric knee flexion test was also conducted by a hand-held dynamometer. After 10 weeks, this prevention program was continued for a further 12-month period. In the group of knee-in alignment, the K/H ratio was improved, and knee flexion muscular strength also improved. The incidence of ACL injuries was not significant, but non-contact ACL injuries decreased compared to the three years prior to conducting this prevention program. By conducting this prevention program, the possibility of decreasing non-contact ACL injuries and improvement of alignment is suggested. [ABSTRACT FROM AUTHOR]
