From the perspective of energy expenditure, this study investigated the effects of whole-body vibration training on the energy metabolism of deep squats with different weights. Twenty-two healthy male college students with sports experiences were selected and randomly assigned to perform resistance exercise vibration (REV) or resistance exercise (RE) with varying loads two times per week for 4 weeks. Oxygen uptake and heart rate were measured before, during, and after exercises using a gas analyzer, and energy expenditure was calculated. The results showed the following: 1) the oxygen uptake and energy expenditure of the REV group were significantly higher than those of the RE group during and 30 min after exercise ( < 0.01), respectively, and the excess post-exercise oxygen consumption (EPOC) was also significantly higher than that of the RE group ( < 0.01). 2) Changes in the oxygen uptake and energy expenditure were stable with increasing exercise in both vibration and non-vibration conditions. There was no difference in energy expenditure per unit of body mass additional energy per kilogram of body weight ( > 0.05). 3) No significant differences in changing exercise intensity were observed in the REV group compared to those in the RE group during the adjacent incremental load phases of △ (40%-0%) and △ (80%-40%) of load during and 30 min after exercise ( > 0.05). Our results suggest that 1) vibration training can increase energy expenditure during low-intensity training and excess post-exercise oxygen consumption, and improve the exercise intensity. 2) The effects on energy expenditure were the same for both weight-bearing and non-weight-bearing deep squats, up to 40% of body mass.
从能量消耗的角度出发,本研究调查了全身振动训练对不同重量深蹲运动能量代谢的影响。选取22名有运动经历的健康男大学生,随机分为两组,分别进行阻力运动振动(REV)或不同负荷的阻力运动(RE),每周训练两次,共4周。在运动前、运动中和运动后,使用气体分析仪测量摄氧量和心率,并计算能量消耗。结果表明:1)REV组在运动期间及运动后30分钟的摄氧量和能量消耗分别显著高于RE组(<0.01),运动后过量氧耗(EPOC)也显著高于RE组(<0.01)。2)在振动和非振动条件下,随着运动量增加,摄氧量和能量消耗的变化较为稳定。单位体重的能量消耗无差异 每千克体重额外增加的能量(>0.05)。3)在运动期间及运动后30分钟,REV组在相邻的△(40%-0%)和△(80%-40%)负荷增量阶段,与RE组相比,运动强度变化无显著差异(>0.05)。我们的研究结果表明:1)振动训练可增加低强度训练期间的能量消耗和运动后过量氧耗,并提高运动强度。2)对于负重和非负重深蹲,高达体重40%时,对能量消耗的影响相同。
