INTRODUCTION
In this study we investigated the effects of resistance training with vibration in combination with leg compression to restrict blood flow on strength, muscle oxygenation, muscle mass, and bone formation.
METHODS
Twelve participants were tested before and after 12 weeks of resistance training with application of vibration (VIBRA; 1-2 mm, 30 Hz) to both legs and compression (∼35 mm Hg, VIBRA+COMP) to only 1 leg.
RESULTS
VIBRA+COMP and VIBRA improved 1 repetition maximum (1-RM), increased the number of repetitions preceding muscle exhaustion, enhanced cortical bone mass, and lowered the mass and fat fraction in the thigh, with no changes in total muscle mass. The mass of cancellous bone decreased to a similar extent after VIBRA and VIBRA+COMP.
DISCUSSION
Resistance training with VIBRA+COMP and VIBRA improved 1-RM, increased the number of repetitions preceding muscular exhaustion, and enhanced formation of cortical bone, with no alteration of muscle mass. Muscle Nerve 56: 1137-1142, 2017.
引言
在本研究中，我们调查了结合振动的抗阻训练以及腿部加压以限制血流对力量、肌肉氧合、肌肉质量和骨形成的影响。
方法
12名参与者在接受为期12周的抗阻训练前后接受测试，训练内容为对双腿施加振动（振动幅度1 - 2毫米，频率30赫兹），仅对一条腿施加加压（约35毫米汞柱，振动+加压）。
结果
振动+加压组和振动组均提高了1次最大重复量（1-RM），增加了肌肉疲劳前的重复次数，增加了皮质骨质量，并降低了大腿的质量和脂肪比例，而总肌肉质量没有变化。振动组和振动+加压组后松质骨质量下降程度相似。
讨论
振动+加压和振动的抗阻训练提高了1-RM，增加了肌肉疲劳前的重复次数，并增强了皮质骨的形成，而肌肉质量没有改变。《肌肉与神经》56: 1137 - 1142, 2017年。
