Effect of core stabilization exercise on risk factors for anterior cruciate ligament injury during single-leg landing in athletes

In sports activities, sudden movements increase the incidence of knee injuries. Stabilization of the core helps prevent knee injuries in sudden movements. However, conventional knee injury prevention exercise programs tend to have a small proportion of the core and focus on knee strength. The purpose of this study was to investigate the effect of core stabilization exercise in single-leg landing in athletes frequently exposed to injury. Participants were recruited through advertisements attached to the hospital's internal bulletin board and participated voluntarily. Thirty-four athletes participated in the experiment, and the exercise program created after distribution to the core stabilization exercise group and the knee strengthening exercise group was applied. In the six-week intervention, the core stabilization group showed a significant improvement in dynamic knee valgus angle and dynamic balance ability compared to the knee strengthening exercise group (p<0.025). It should be considered to increase the proportion of core stabilization exercises in the exercise program to prevent knee injuries in athletes.
