| 摘 要： | 以30名男性自行车运动员为受试对象,通过对其分别进行15 min蹬车和15 min蹬车/PNF拉伸两套不同方案的训练,训练后对其进行最大肌力、力量-时间曲线的主要指标以及下肢肌肉的肌电图测试与对比分析,以期探讨PNF牵伸练习对运动员肌肉力量、力量-时间曲线参数、EMG参数的影响.结果显示:自行车运动员进行下肢FNF牵伸练习不会引起最大肌力和力量-时间曲线的参数(MVC、F100、IRF和TMVC)的显著性下降,股直肌的肌电电压却发生显著性下降.

| Abstract: | 30 Cyclists are tested after 15-minute paddling and paddling/PNF stretching respectively,their maximum strength,strength-time curve and electromyography of leg muscles are collected and analyzed comparatively,in order to explore the effect of PNF stretching on cyclists' muscle strength,strength-time curve parameter and EMG parameter.Conclusion: results indicate that PNF stretching does not alter the MVC and the isometric strength-time curve parameter(MVC,F100,IRF and TMVC) significantly,but the myoelectrici... |
