To investigate whether whole body vibration (WBV) training increases the explosive force of the knee extensors in chronic kidney disease (CKD) patients. Fourteen CKD patients undergoing hemodialysis were randomly allocated in WBV training or Sham group. Explosive force parameters (contractile impulse [CImp] and relative rate of force development [RFDr]) obtained in early (30 and 50 msec) and late phases (100 and 200 msec) of the knee extensors force/time curve. CImp and RFDr obtained at the early phase of force/time curve reduced after the intervention period, with a smaller decline for WBV (CImp at 50 msec [-15% and -51%, =0.038], RFDr at 30 msec [-22% and -52%, =0.044] and RFDr at 50 msec [-11% and -54%; =0.008]). In the late phase there was a lower decline for WBV group compared to Sham group, respectively: CImp: 100 msec (-8% and -55%, =0.025), 200 msec (-3% and -46%, = 0.025); RFDr 100 msec (0.01% and -56%, =0.033), 200 msec (~-5% and -36%, =0.004). Three months of WBV training may attenuate the explosive force reduction in CKD patients.
为研究全身振动（WBV）训练是否能增强慢性肾脏病（CKD）患者膝伸肌的爆发力。14名接受血液透析的CKD患者被随机分配至WBV训练组或假手术组。在膝伸肌力量/时间曲线的早期（30和50毫秒）和晚期（100和200毫秒）获取爆发力参数（收缩冲动[CImp]和相对力量发展速率[RFDr]）。在干预期后，力量/时间曲线早期获得的CImp和RFDr降低，WBV组下降幅度较小（50毫秒时的CImp[-15%和-51%，P = 0.038]，30毫秒时的RFDr[-22%和-52%，P = 0.044]以及50毫秒时的RFDr[-11%和-54%；P = 0.008]）。在晚期，与假手术组相比，WBV组下降幅度更低，分别为：CImp：100毫秒（-8%和-55%，P = 0.025），200毫秒（-3%和-46%，P = 0.025）；RFDr 100毫秒（0.01%和-56%，P = 0.033），200毫秒（~-5%和-36%，P = 0.004）。三个月的WBV训练可能会减轻CKD患者爆发力的下降。
