The anterior cruciate ligament (ACL) is one of the most commonly injured ligaments of the knee.This study investigated the effects of core stability training on trunk kinematics including trunk flexion and lateral flexion in female athletes with neuromuscular deficit of trunk control to prevent ACL injury. Twenty-two female athletes were randomly assigned into a training group (n = 11), performing the functional stabilization training during 6 weeks, and a control group (n = 11,) without any physical training. The kinematic assessment of the trunk with motion analysis system was performed during a single-leg drop landing before and after training. After 6 weeks, the TG significantly increased the value for trunk flexion (from 20.08 to 27.67), but there wasn’t any significant reduction in trunk lateral flexion (p=0.314). Core stability training program used in the current study successfully increased trunk flexion in training group. It can be stated that probability with increasing core stability, muscles recruitment strategy may have improved. We concluded that, 6-week training in female athletes with deficit in trunk neuromuscular control can result in reduction of modifiable risk factors of ACL injury including biomechanical and neuromuscular factors.
