Whole body vibration (WBV) with resistance training is one of the increasing ways of gaining ankle and foot complex muscle strength and power for the rehabilitative and prophylactic purpose in athletes.
The purpose of the study was to compare the effects of combined WBV and resistance training (RVE) with strength training alone (RE) on alteration of gastrocnemius lateralis and vastus medialis obliquus muscle activity and strength, and power performance in athletes.
The study was performed on 23 university-level male athletes who were randomized into two groups as RVE (n = 12; age 22.2 ± 1.94 years) and RE (n = 11; age 21.60 ± 1.78 years). The training program was scheduled three times per week for six weeks (18 sessions). Gastrocnemius lateralis (GL) and vastus medialis obliquus (VMO) were measured for muscle activity and isometric strength with surface EMG device and handheld dynamometer respectively. Counter-movement jump (CMJ) was used for measuring power. All the participants were assessed for outcome measures at baseline and then after 6 weeks. Group (RVE vs. RE) by time (pre vs. post) effects were compared through a 2-way interaction utilizing mixed model repeated measure ANOVA.
After training, VMO muscle activity (group effects) increased significantly in the RVE group (p < 0.05). However, both the groups showed statistically significant time and group × time interaction effects for muscle activity of VMO, isometric strength (VMO and GL), and CMJ (p < 0.05).
WBV might serve as an adjunct modality for enhancement of the neuromuscular activity of the VMO muscle. However, RVE had no additive effect when compared to RE alone on muscle strength and power in athletes. The long-term impacts of combined WBV and resistance training on other foot and ankles muscle should be investigated in future studies.
全身振动（WBV）结合抗阻训练是一种增加踝关节和足部复合肌肉力量和力量的方法，目的是在运动员中进行康复和预防。
本研究旨在比较组合 WBV 和抗阻训练（RVE）与单独力量训练（RE）对运动员腓肠肌外侧和股直肌外侧活动和力量以及力量表现的影响。
研究对象为 23 名大学水平的男性运动员，随机分为两组，即 RVE 组（n=12；年龄 22.2±1.94 岁）和 RE 组（n=11；年龄 21.60±1.78 岁）。训练方案每周进行三次，共六周（18 次）。使用表面肌电图设备和手持测力计分别测量腓肠肌外侧（GL）和股直肌外侧（VMO）的肌肉活动和等长力量。采用反向跳（CMJ）测量功率。所有参与者均在基线和 6 周后评估结果。采用混合模型重复测量方差分析的 2 因素交互作用比较组（RVE 与 RE）与时间（前与后）的影响。
训练后，RVE 组 VMO 肌肉活动（组间效应）显著增加（p<0.05）。然而，两组的 VMO、等长强度（VMO 和 GL）和 CMJ 的肌肉活动均显示出统计学上显著的时间和组×时间交互作用（p<0.05）。
WBV 可能作为增强 VMO 肌肉神经肌肉活动的辅助手段。然而，与单独的 RE 相比，RVE 对运动员的肌肉力量和力量没有附加作用。未来的研究应探讨联合 WBV 和抗阻训练对其他足部和踝关节肌肉的长期影响。
