Plyometric intensity assessed from joint and musculotendinous load

本研究旨在通过运动分析和肌肉功能MRI来研究增强运动（PM）的强度水平。结果表明，从关节机械输出中评估的强度水平与传统的PM强度分类不同。此外，运动类型对关节机械输出的影响在下肢关节间存在差异。此外，协同作用肌的肌肉激活也有显著差异。

The present study aimed to investigate the intensity levels of plyometric (PM) exercises using a motion analysis and muscle functional MRI. The results indicate that the intensity level assessed from the joint mechanical output differed from that suggested in traditional classification of PM intensity. In addition, influence of exercise type on the joint mechanical output differed among the lower limb joints. Furthermore, there were significant differences in muscle activation among synergist muscles.
