12 female excellent beach volleyball players were volunteered to join in the test of isokinetic concentric strength of knee and ankle joint flexor and extensor by dynamometer-BIODEX with the methods of reading up the documents and measuring statistics in front and behind of annual period of beach volleyball training.
为探讨在沙滩这种特殊的介质上进行排球训练对运动员膝、踝关节肌群肌力的影响 ,在 1998年沙滩排球训练周期前后 ,对我国 12名兼职沙滩女排运动员的膝、踝关节屈伸肌群进行了等速向心收缩肌力测试。
4) isovolumic contraction period
等容收缩期
1.
Purpose: In the current study,a new technique,tissue velocity imaging(TVI),was employed to evaluate the asynchrony of left ventricle(LV) during isovolumic contraction period in patients of dilated cardiomyopathy(DCM).
目的:探讨原发性扩张型心肌病(DCM)左室等容收缩期心肌收缩协调性的意义。
补充资料：等容收缩期
等容收缩期
当心室收缩时，心室内压力迅速增高，当室内压高于心房内压时，心室内血液即推动左、右房室瓣而使其关闭，血液不致倒流入心房。在心室内压力未超过主动脉压和肺动脉压之前，半月瓣仍在关闭状态。在此短时间内(在人约为0．06秒），房室瓣与心室瓣均关闭，心室肌纤维长度即心室的容积未变而仅有张力的变化，称之为等容收缩期。
