| Objective:In this study,six week intervention training was used to compare and explore the effect of core stability training on the risk of ACL injury in posture control and landing movements,so as to provide reference and reference for injury prevention in the future.Research methods: 36 college students of Shandong Institute of physical education were randomly recruited as test subjects,and they were trained in core stability for 6 weeks,3 times a week,30 minutes each time.Before and after the experiment,core stability test,y balance test and less test were conducted.Training intervention and gender control ability of dynamic posture and landing action were determined by 2 × 2 mixed design ANOVA Influence of technical test results.Results:(1)the endurance of trunk extensor,trunk flexor and lateral bridge were significantly improved after training in core stability test(P > 0.05).(2)In the y-balance test,the distance and total score in three directions were significantly improved,but there was no gender difference(P > 0.05);there was no difference between left and right forward distance(P > 0.05),and there was no gender difference(P > 0.05).(3)In the landing movement mode,the knee flexion angle,hip flexion angle and genu valgus angle were significantly increased(P < 0.05),and there was gender difference in the knee valgus angle at the maximum moment of knee flexion(P > 0.05);the trunk roll angle was not significantly improved at the time of landing(P = 0.085);the landing technique score was significantly improved(P < 0.05).Conclusion: 1)core stability training can improve the ability of dynamic posture control.2)Core stability training can improve landing movement mode and reduce the risk of ACL injury.3)There is no significant gender difference in the core stability training in posture control and landing technology,and there is significant gender difference in the knee valgus angle only at the maximum moment of knee bending in landing movement mode. |
