摘要
目的:探讨肌内效贴对离心运动后即刻肌肉力量和动态平衡能力的影响,为降低运动损伤风险提供理论依据.方法:招募30名非体育专业健康男性大学生,随机均分为3组(对照组、加压组、肌贴组),每组10人.加压组、肌贴组运动前分别在大腿前部使用弹性绷带和肌内效贴,并在运动前和运动后即刻测试优势侧下肢Y平衡和等速肌力.结果:运动前3组受试者伸膝肌群相对峰力矩、平均功率、平均峰力矩、Y平衡各方向结果差异均无统计学意义(P>0.05).运动后,3组受试者伸膝肌群相对峰力矩、平均功率、平均峰力矩较运动前均显著下降(P<0.05),但各组间比较差异无统计学意义(P>0.05).运动后,3组受试者下肢Y平衡测试在前、后内、后外3个方向最大距离较运动前均显著下降(P<0.05);肌贴组与加压组在3个方向最大距离较对照组差异均有统计学意义(P<0.05).结论:大强度运动可诱发下肢肌群疲劳,肌内效贴不能促进肌力恢复,但能改善下肢动态平衡能力.
Abstract
Objective:To investigate the effects of kinesio taping(KT)on muscle strength and dynamic balance ability immediately after eccentric exercise,and to provide theoretical basis for reducing the risk of sports injury.Methods:30 healthy male college students were recruited and randomly divided into 3 groups(control group,pressure group and KT group)with 10 people in each group.For pressure group and KT group,lastic bandage and kinesio taping were applied to the front of the thigh before exercise,and Y balance and isokinetic muscle strength of the dominant lower extremity were tested before and immediately after exercise,respectively.Results:Before exercise,there were no significant differences in the relative peak moment,average power,average peak moment and Y balance of knee extensor muscle in 3 groups(P>0.05).After exercise,the relative peak moment,average power and average peak moment of knee extensor muscle in 3 groups were significantly decreased compared with before exercise(P<0.05).There was no significant difference among all groups(P>0.05).After exercise,the maximum distance of Y balance test of lower limbs in front,inside and outside directions of 3 groups was significantly decreased compared with that before exercise(P<0.05).Compared with the control group,there were significant differences in the maximum distance in 3 directions between the KT group and the pressure group(P<0.05).Conclusion:High intensity exercise can induce fatigue of lower limb muscle group,and kinesio taping can not promote muscle strength recovery,but can improve lower limb dynamic balance ability.
