摘要
研究运用遥测肌电和图像解析的方法,对天津市体操队19名男性体操运动员单杠引体向上反手宽握、中握和宽握颈后拉三个动作进行定量分析。研究结果表明:单杠引体向上反手宽握与中握和宽握颈后拉三个动作对发展体操运动员背阔肌和肱桡肌起主导作用,运动单位的动员率也最高;三个动作对发展斜方肌和胸大肌的效果一致,无论是放电量或肌肉的激活程度相对稳定。反手宽握颈后拉动作对发展体操运动员肱二头肌和桡侧腕屈肌的作用效果和运动单位的激活率明显好于其他两种方法;反手中握对尺侧腕屈肌的作用效果优于反手宽握和宽握颈后拉;单杠引体向上反手宽握与中握和宽握颈后拉对发展桡侧腕屈肌的效果呈递增状态。
Depnding on telemetric EMG signal and image analysis methods, the research quantitatively analyzes 19 male gymnasts from Tianjin gymnastics team for their three kinds of horizontal bar chin - up actions, wide backhand grips, backhand grips and backhand neck -behind grips. The results show that： each of the three actions plays a dominant role in the development of gymnasts＇latissimus dorsi and brachioradialis ,with the mobilization of the motor unit rate being the highest; the three actions produce the same effects on developing trapezius muscle and the pectoralis major, with both discharge amount and degree of activation of the muscle being relatively stable ; neck - behind wide backhand grips develop gymnasts＇biceps and flexor carpi much better and the activation of motor unit rate is considerably higher than the other two kinds; the effect backhand grip on lexor carpi building is superior to the others and at last, the three horizontal bar chin - ups from backhand wide grip, grip to neck - behind grip develop flexor carpi power increasingly one by one.
