穴位电刺激增强运动员快速力量的作用观察

Electrical acupoint stimulation increases athletes' rapid strength

目的:寻找提高运动员成绩的有效刺激方法。方法:将150名运动员随机分为试验组和对照组两组,每组75人。以多盲的试验方法,通过音频脉冲调制波刺激穴位(大椎、命门、足三里、承山),并观察穴位电刺激对运动员的30m跑、站立式跳远、Cybex等动测试指标的影响。结果:穴位电刺激方法可以显著提高运动员的运动成绩(P<0.05)及最大峰力矩(P<0.05)、力矩加速能(P<0.05)和平均功率(P<0.05)的生物力学指标。结论:穴位电刺激的方法可增强运动员快速力量。

Objective To search for a stimulation method for increasing athletes＇ performance. Methods One hundred and fifty athletes were randomly divided into a trial group and a control group, 75 athletes in each group. Acupoints were stimulated with audio frequency pulse modulated wave and multi-blind method were used to investi gate effects of the electric stimulation of acupoints on 30-meter running, standing long jumping and Cybex isokinetic testing index. Results The acupoint electric stimulation method could significantly increase athlete＇s performance （P〈0.05）, and the biomeehanieal indexes, maximal peak moment of force （P〈0.05）, force moment accelerating energy （P〈0.05） and average power （P〈0.05）. Conclusion Electrical acupoint stimulation can enhance athlete＇s rapid strength.
