Abstract: BACKGROUND: Studies have shown that poor dynamic postural control may lead to abnormal movement patterns during exercise, which may increase the risk of lower limb joint and anterior cruciate ligament injury. The stability of the body core is the basis of good dynamic postural control.
OBJECTIVE: To investigate the effects of core stability training on dynamic postural control and risk of injury in landing movements, and to compare the differences in training effects between genders. 
METHODS: Thirty-five college students (male=19, female=16) were recruited for 6 weeks of core stability training. The results of the Y balance test, trunk extensor endurance test, trunk flexor endurance test, lateral bridge endurance test, and landing error scoring system were analyzed before and after training. 
RESULTS AND CONCLUSION: The 6-week core stability training could improve trunk extensor endurance (P < 0.001), flexor endurance (P < 0.001), and lateral abdominal muscle endurance (P < 0.001). Core stability training could improve forward distance (P=0.026), backward inward distance (P < 0.001), backward outward distance (P=0.005) and comprehensive score (P < 0.001) of Y balance test for male and female college students. Landing error scoring system scores of both male and female college students significantly decreased after 6 weeks of core stability training (P < 0.001) while increasing knee (P < 0.001) and hip flexion angles (P < 0.001), decreasing knee valgus angle (P < 0.001) at the moment of touchdown, and could increase the maximum knee flexion angle (P < 0.001) and decrease the maximum knee valgus angle (P < 0.001). It is concluded that core stability training improves dynamic postural control and improves landing movement patterns, suggesting that it may help reduce the risk of anterior cruciate ligament injury. There are no sex differences in core stability training in terms of increased trunk flexor endurance, lateral bridge muscle group endurance, improved dynamic postural control, and reduced risk of anterior cruciate ligament injury.

Key words: core training, dynamic postural control, landing movement, anterior cruciate ligament injury, core stability
