摘要
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。结果表明 ,沙滩训练后 ,膝关节屈肌群快肌纤维的爆发力 ,伸肌群快肌纤维的最大肌力和爆发力 ,踝关节跖肌群慢、快肌纤维的最大肌力和爆发力增长有显著性意义。
In order to probe into the influence of beach volleyball training on the volleyball players' jumping ability.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.The results show that after beach volleyball training are finished,the peak torque,the relative peak torque,the total work decreased with the increasing of speed,but average power and the ratio between agonist and antagonist increased with the increasing of speed.Moreove,beach volleyball training has marked effects on explosive force of flexor's fast muscular fibers of knee joint,maximum muscular strength and explosive force of extensor's fast muscular fibers of knee joint,and maximum muscular strength and explosive force of extensor's fast and slow muscular fibers of ankle joint.These are the most important reasons for the improvement of the height of original place jump on the floor.
