Objective. We aimed to investigate the acute residual hormonal, biochemical, and neuromuscular responses to a single session of individualized whole-body vibration (WBV) while maintaining a half-squat position. Methods. Twenty male sport science students voluntarily participated in the present study and were randomly assigned to an individualized WBV group (with the acceleration load determined for each participant) or an isometric group (ISOM). A double-blind, controlled parallel study design with repeated measures was employed. Results. Testosterone and growth hormone increased significantly over time in the WBV group (P < .05 and P < .01, respectively; effect size [ES] ranged from 1.00 to 1.23), whereas cortisol increased over time in both groups (P < .01; ES ranged from 1.04 and 1.36). Interleukin-6 and creatine kinase increased significantly over time only in the WBV group (P < .05; ES = 1.07). The maximal voluntary contraction decreased significantly over time in the ISOM group (P = .019; ES = 0.42), whereas in the WBV group, the decrease did not reach a significant level (P = .05). The ratio of electromyographic activity and power decreased significantly over time in the WBV group (P < .01; ES ranged from 0.57 to 0.72). Conclusion. Individualized WBV increased serum hormonal concentrations, muscle damage, and inflammation to levels similar to those induced by resistance training and hypertrophy exercises.

目标。我们旨在研究在保持半蹲姿势的情况下，对单个会话的全身振动（WBV）的急性残留激素，生化和神经肌肉反应。方法。二十名男性体育科学专业学生自愿参加了本研究，并随机分配到一个个性化的WBV组（为每个参与者确定加速负荷）或一个等距组（ISOM）。采用双盲，对照平行研究设计，并采用重复测量。结果。随着时间的推移，WBV组的睾丸激素和生长激素显着增加（P <.05和P分别<.01；[ES]的作用范围为1.00至1.23），而两组的皮质醇随时间增加（P <0.01； ES的范围为1.04和1.36）。仅在WBV组中，白介素6和肌酸激酶随时间显着增加（P <.05； ES = 1.07）。随着时间的流逝，ISOM组的最大自发性收缩显着下降（P = .019； ES = 0.42），而WBV组则没有达到显着水平（P = .05）。WBV组的肌电活动和功率比率随时间显着下降（P <.01； ES在0.57至0.72之间）。结论。 个体化WBV使血清激素水平，肌肉损伤和炎症增加至类似于抵抗训练和肥大运动所诱发的水平。
