振动训练作用目标主要是肌肉中弹性成分的实验研究

Experimental Research on Muscle Elastic Components of the Effects of Vibration Training

该研究将32名受试者分为三个实验组进行了为期8周的下肢肌肉力量振动训练实验研究,通过影像测量和动力学测量采集实验前、后30cm和50cm两种高度跳深的净冲量、反跳高度及反跳比数据。对实验数据分析表明,有附加振动刺激的动态性负重蹲练习方式其数据提高幅度优于静态力量练习方式和无附加振动练习方式。对比分析三个实验组的数据差异表明,有附加振动刺激的下肢肌肉力量训练主要是通过促进下肢肌肉中弹性成分的增强而获得肌肉力量的提高。对比分析两个不同跳深高度的数据表明,下肢肌肉对外力冲量的利用受下肢肌肉储能能力的影响,有附加振动刺激的实验组其下肢肌肉储能能力比无附加振动刺激的实验组要强。

The research divides 32 subjects into three experimental groups to conduct an 8 -week experiment of muscle strength of lower limbs through vibration training. The research uses image measurement and dynamic measuremerit to collects data of net impulse, rebound height and rebound ratio before and after the experiment in 30cm and 50cm - depth jumping. The results show that the group of weight deep squat vibration increases most, the group of half weight squat static vibration follows and the group of squat vibration ranks last. The analysis shows that vibration training is mainly to promote the elastic component lower limb muscles to improve the muscle strength. Comparative analysis of the 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 extremity muscle is much better than non vibration experimental group.
