[Purpose] Optimization of post-training muscle recovery is important in clinical rehabilitation and sports science. In this study, we investigated the effects of local vibration stimulation on post-training muscle recovery and hypertrophy in healthy adults, focusing on the upper extremities. [Participants and Methods] The study included 20 healthy students categorized into the control and vibration stimulation groups. Both groups underwent training, including elbow flexion. The vibration stimulation group received immediate post-training local vibration stimulation. Evaluation included measurement of upper arm circumference, muscle strength, muscle hardness, and ultrasonographic imaging. [Results] Our results showed that local vibration stimulation increased muscle luminosity but had no significant effect on muscle strength, hardness, or thickness. [Conclusion] Post-training vibration stimulation may promote muscle growth and recovery by stimulating blood flow and improving nutrient and oxygen supply to muscles.
[目的] 优化训练后肌肉恢复在临床康复和运动科学中至关重要。在本研究中，我们调查了局部振动刺激对健康成年人训练后肌肉恢复和肥大的影响，重点关注上肢。[参与者和方法] 该研究纳入了20名健康学生，分为对照组和振动刺激组。两组均进行了包括肘部屈曲的训练。振动刺激组在训练后立即接受局部振动刺激。评估包括测量上臂围、肌肉力量、肌肉硬度和超声成像。[结果] 我们的结果表明，局部振动刺激增加了肌肉亮度，但对肌肉力量、硬度或厚度没有显著影响。[结论] 训练后振动刺激可能通过刺激血流和改善肌肉的营养和氧气供应来促进肌肉生长和恢复。
