eccentric contraction

The eccentric contraction of both sides ′ quadriceps and hamstring produced significantly higher torques than concentric contraction did in same speed .

相同速度下，患侧和健侧股四头肌和腘绳肌离心收缩肌力明显大于向心收缩；

The eccentric contraction ability of the extensor of knee joint and ankle joint and fast contraction ability of the flexors in ankle joint determine the buffer effect of landing ;

膝、踝关节伸肌的离心收缩能力以及踝关节屈肌的快速力量主要影响踏跳动作的缓冲效果；

It is unreasonable rate that training of muscle of supporting leg eccentric contraction and concentric contraction .

苏州优秀短跑运动员支撑技术不够合理，其与训练中对支撑腿肌肉进行退让与克制性收缩力量比例不合理有关。

The test results were carried on statistics processing , compared the different effects on fast strength of lower body from different eccentric contraction speed . Results : 1 .

结果进行统计处理，比较不同速度离心力量训练对下肢快速力量的不同影响。

This paper was to investigate whether prior heat stress had protective in rats against eccentric contraction induced muscle damage , and discussed the mechanism of mechanism effect of prior heat stress .

观察预热应激对大鼠骨骼肌离心运动损伤是否具有保护作用，并对预热应激的保护作用机制进行探讨。

The results showed that after eccentric contraction immediately , the production of MDA increased largely and peaked after one day . As a result , the role of lipid peroxidation damaging the cell membranes and the injuries of skeletal muscles became more serious .

结果显示：离心运动后即刻骨骼肌MDA生成大量增加，运动后1天达峰值，脂质过氧化作用破坏了细胞膜，骨骼肌损伤进一步加重。

When taking the same speed , IEMG of concentric contraction was significantly larger than eccentric con-traction but the ratio of work to IEMG of eccentric contraction was much higher than concentric contrac-tion .

收缩速度相同，向心收缩的IEMG明显大于离心收缩，而离心收缩的功与IEMG比值明显大于向心收缩。

Conclusion : Patients with knee OA have deficits in concentric and eccentric strength of quadriceps , which suggests that the muscle function test of patients with knee OA should include eccentric contraction test , and that patients with knee OA should enhance eccentric exercise of quadriceps .

结论膝OA患者股四头肌存在向心和离心收缩功能异常，提示膝OA患者的肌肉功能测试应增加离心测试，并注意加强膝OA患者股四头肌的离心收缩训练。
