快速伸缩复合练习伴随血流限制的激活后增强效应研究

Effect of post-activation potentiation induced by combining plyometrics and blood flow restriction

[目的]观察快速伸缩复合练习、血流限制,以及两者相结合对纵跳的动力学和运动学的影响.[方法]对象为运动训练专业男性大学生.随机分为对照组(C)、快速伸缩复合练习组(P)、血流限制组(B),以及快速伸缩复合练习伴随血流限制(P+B).分别在干预前、干预后测定纵跳的运动学和动力学参数.[结果]P组与P+B组在干预4 min后,有类似的显著效果;但B组不显著.[结论]单独使用血流限制不能产生激活后增强效应;快速伸缩复合练习及其与血流限制相结合,能够产生激活后增强效应.

[Purpose]To investigate the post-activation potentiation(PAP)effect of plyometrics,blood flow restriction and their combination on kinetics and kinematic parameters in vertical jump performance.[Methods]Objects are male strength-trained students.They were randomly divided into four groups:control(C),plyometrics(P),blood flow restriction(B)and plyometrics combined with blood flow restriction(P+B).Vertical jumping performance were measured before intervention and after.[Results]The results of Group P and Group(P+B)are similar at 4 min,while Group B are not.[Conclusions]Blood flow restriction could not induce the PAP effect.Plyometrics combined with blood flow restriction had the PAP effect.
