This study was undertaken to analyze the effects of different vibration recovery strategies via feet or hands on the number of repetitions performed and on mean velocity, peak velocity and blood lactate concentration during consecutive bench-press sets. 9 elite judo athletes performed 3 sets of bench press at 60% of one-repetition maximum (1RM), leading to failure and allowing a 180 s rest period between sets. During the rest period, 1 of the 3 following procedures was performed: 150 s rest plus 30 s push-up vibration exercise (Push-up), 150 s rest plus 30 s squat vibration exercise (Squat) or 180 s only rest (Passive). Statistical analysis revealed that the Squat condition resulted in a significant increase in the number of repetitions achieved, in comparison with all other rest strategies. However, kinematic parameters and blood lactate concentration were not affected by vibration. These data suggest that a vibration stimulus applied to the feet, between sets, can result in positive improvements in upper body resistance exercise performance. Although the mechanisms are not fully understood, this positive effect of vibration could be due to an increased motor cortex excitability and voluntary drive.
本研究旨在分析通过脚或手进行不同振动恢复策略对重复次数、平均速度、峰值速度和连续卧推组间血乳酸浓度的影响。9 名精英柔道运动员以 1 次重复最大重量（1RM）的 60%进行 3 组卧推，导致力竭并允许每组之间休息 180 秒。在休息期间，执行以下 3 个程序中的 1 个：150 秒休息加 30 秒俯卧撑振动练习（俯卧撑），150 秒休息加 30 秒深蹲振动练习（深蹲）或仅 180 秒休息（被动）。统计分析显示，与所有其他休息策略相比，深蹲条件导致完成的重复次数显著增加。然而，运动学参数和血乳酸浓度不受振动影响。这些数据表明，在组间施加到脚部的振动刺激可以导致上半身抗阻运动表现的积极改善。尽管机制尚不完全清楚，但振动的这种积极影响可能归因于运动皮层兴奋性和自愿驱动的增加。
