Whole body vibration (WBV) exercises have been investigated as an alternative and complementary method to traditional resistance programs for fitness improvements in healthy subjects. Active militaries must have a high fitness level and have to improve some physical abilities to accomplish some specific tasks in Army, as climb ropes, climb walls and pull up.
Seven young and healthy soldiers from Brazilian Army were exposed to mechanical vibration in a push-up position, with different frequencies, as 25 (first session), 30 (second session), 35 (third session), 40 (fourth session) and 45 Hz (fifth session). The WBV intervention consisted of five WBV sessions over a consecutive two and a half-weeks period of time. A WBV session consisted of twenty bouts, each one with 10- second vibration, interspersed with 10 seconds of passive rest and 4 minutes pause after the first 10 bouts. Handgrip strength was measured, as proposed by American Society of Hand Therapists - ASHT, before and after the session using 25 Hz of frequency and 45 Hz of frequency (1 and 5 sessions).
No significant results were found between groups.
Intervention of WBV exercises with 25 and 45 Hz of frequency applied by hands of healthy and young soldiers had no significant results. Further investigations should focus on the efficacy of WBV in the improvement of handgrip strength of young and healthy people.
全身振动（WBV）训练已被作为一种替代和补充方法进行研究，用于帮助健康受试者通过传统阻力训练计划来改善身体素质。现役军人必须具备较高的身体素质水平，并需要提高某些身体能力，以完成军队中的一些特定任务，如攀爬绳索、攀爬墙壁和引体向上。
七名来自巴西陆军的年轻健康士兵在做俯卧撑姿势时接受不同频率（25Hz，第一次训练；30Hz，第二次训练；35Hz，第三次训练；40Hz，第四次训练；45Hz，第五次训练）的机械振动。WBV干预在连续两周半的时间内进行了五次训练。一次WBV训练包括二十组，每组振动10秒，中间穿插10秒的被动休息，前10组后有4分钟的暂停。按照美国手治疗师协会（ASHT）的建议，在使用25Hz频率（第一次训练）和45Hz频率（第五次训练）的训练前后测量握力。
各组之间未发现显著结果。
健康年轻士兵通过双手施加25Hz和45Hz频率的WBV训练没有显著效果。进一步的研究应聚焦于WBV对改善健康年轻人握力的功效。
