运动前肌肉牵拉对纵跳能力影响的比较研究

目的:探索运动前不同方式的肌肉牵拉对纵跳能力的影响,为爆发力项目合理进行准备活动提供参考.方法:19名受试者分别于进行20 s×3次静态持续的下肢肌肉牵拉和20次×3组动力性下肢肌肉牵拉后在测力台上分别进行蹲跳和反向移动跳测试;9名受试者作为对照组,在不进行肌肉牵拉的情况下同时进行相同测试,比较其跳跃高度和平均功率.结...

Investigation of the effect of preceding muscle stretch on vertical jump ability

Objective: to investigate the effect of preceding muscle stretch on vertical jump ability to provide consult for the warming-up of the explosive sports.Method:19 subjects carried through static stretch of lower limbs muscle 20 s×3 sets,and dynamic stretch of lower limbs muscle 20rep×3sets respectively,then executed squat jump(SJ) and counter movement jump(CMJ) on the force plate,respectively,and then compared the jump height and average power.Results: the height of CMJ declined significantly(p<0.01)after static stretch of lower limbs muscle,whereas the height of SJ had not significant change,after dynamic muscle stretch,the height of SJ enhanced significantly(p<0.05)yet the height of CMJ had not significant change.Conclusion: sustaining static stretch might increase the elasticity of muscle,then lowered the ability of muscle to utilize the elastic potential energy during,thus produced negative effect on the explosive strength,however,dynamic muscle stretch may have positive effect on the concentric contraction.
