简介:BackgroundTraditional垂直、轮流出现方面的整个身体颤动(WBV)能有效地改进肌肉力量性能,但是为提高change-of-direction(货到付款)有有限功效能力。特别地为每条腿向运动的各种各样的方向提供更高、特殊的频率的新奇双板的WBV可以在肌肉力量和短弄短的周期功效贡献货到付款能力上引起更好尖锐的效果。因此,这研究的目的是调查双频率或单个频率的WBV的尖锐效果在上蹲跳(SJ),countermovement跳(CMJ),怪癖的利用比率(EUR),,和4min部分在一台双板的WBV机器上与WBV协议的3种类型蹲包括有收到35Hz的主导的腿和收到45Hz的非主导的腿的1个双频率的WBV协议(DFW),并且2single-fp=0.008;CMJ:p<0.001),但是显著地没改变EUR(p>0.05)。另外,仅仅DFW显著地改进了双频率的WBV会议改进了在橄榄球播放器的垂直的跳和货到付款能力的货到付款能力(p=0.001).ConclusionA4min,建议这能是为运动员的一个潜在的热身运动协议。
