【摘要】 文章主要研究在不同振动波条件下对肌肉力量训练效果的影响。以33名大学男生为研究对象,在不同方向振动波的条件下进行负重蹲实验。以三维影像与三维测力台同步测量系统采集跳深和负重蹲动作的运动学及动力学数据;以瑞士等速肌力测试系统采集膝关节在不同速度时向心、离心运动的肌力学数据。分析结果认为,振动波方向影响肌肉振动训练的效果。振动波方向与肌纤维纵轴之间趋向于垂直状态或形成较大角度时,振动波能够对肌肉产生较大的刺激。振动波与肌纤维的角度过小或成平行状态时,振动波对肌肉的刺激作用便相对较小。肌纤维受到与其呈大角度的振动波的作用时间越长,便越能对肌肉能力的增强产生较大的影响。更多还原

【Abstract】 32 subjects are divided into three groups to receive an 8- week experimental research on their lower limbs’ vibration training. Image measurement and dynamic measurement are adopted in the research to collect the data of net impulse,rebound height and rebound rate of 30cm and 50cm in- depth jumping before and after the experiment. The results show that data of the dynamic deep squat weight training with vibration increases more than either that of static strength training or static vibration training. The analysis shows that vibration training is mainly to promote the elastic component of lower limb muscles by improving the muscle strength. Comparative analysis of two kinds of data indicates that the ability of energy storage of lower limb muscle affects the use of force. The capacity of energy storage in vibration experiment group of lower limb muscle is much better than that in the non vibration experimental group.更多还原
