肌内效贴对纵跳动力学特征及小腿肌肉活动的影响

为探索肌内效贴贴扎小腿腓肠肌对纵跳动力学特征及小腿其他肌肉活动的影响，本文对10名国家二级及以上水平运动员进行无、有贴扎纵跳实验，每组5人随机进行纵跳实验，重复3次，选择最佳测试成绩进行对比分析。结果表明，肌内效贴能够提高纵跳高度（P＜0.01），增加最大蹬伸力和最大缓冲力（P＜0.05），对蹬伸时间和最大蹬伸力梯度也有影响（P＜0.05）；同时，在蹬伸阶段，肌内效贴贴扎使双腿内侧腓肠肌积分肌电（iEMG）和均方根振幅（RMS）增加（P＜0.05），使一侧胫骨前肌iEMG和RMS减少（P＜0.05）。但在缓冲阶段，对小腿各肌肉IEMG和RMS均无显著性差异（P＞0.05）。可见，肌内效贴使部分纵跳动力学特征发生改变，对小腿内侧腓肠肌肌肉活动也有促进作用。

Effect of Kinesio Taping on the Dynamic Characteristics of Vertical Jump and Calf Muscle Activities

To explore the effect of kinesio taping on calf gastrocnemius on the dynamic characteristics of vertical jump and other muscle activities. In this study, ten athletes of the national level two and above were selected for the vertical jump experiment with or without taping. There were 5 athletes in each group, and each of them did vertical jump three times. The best results were chosen for comparative analysis. The result shows that kinesio taping can increase the height of vertical jump (P< 0.01) and increase maximum stretch and maximum buffer force (P< 0.05). And it has an effect on the stretch time and maximum stretch gradient (P< 0.05). At the same time, iEMG and RMS in the medial gastrocnemius muscle increase (P < 0.05) at the stretch stage. And this reduces iEMG and RMS in the one side anterior tibial muscle (P < 0.05). Yet at the buffer stage, there is no significant difference between the iEMG and RMS of the different calf muscles (P>0.05). Therefore, kinesio may alter the changes of the part of the dynamic characteristics of vertical jump and improve the muscle activities of calf medial gastrocnemius.
