尽管全身振动训练在运动员中的应用越来越广泛，但目前尚不清楚在短跑运动员的常规训练中加入全身振动训练是否会提高速度-力量表现。20名经验丰富的短跑运动员（13名男性，7名女性，17-30岁）被随机分配到全身振动组（n = 10:6男性和4女性）或对照组（n = 10:7男性，3女性）。在为期5周的实验期间，所有受试者都继续他们的常规训练计划，但全身振动组的受试者在常规训练计划之前每周额外进行三次全身振动训练。全身振动方案包括在振动平台（35 - 40 Hz, 1.7 - 2.5 mm, Power PlateO）上进行的卸载静态和动态腿部练习。在固定阻力下，通过电机驱动测力仪（Rev 9000, Techno-gym (R)）测量前后等距和动态（100度/秒）膝关节伸肌和屈肌强度和膝关节伸肌速度。垂直跳跃性能通过接触垫测量。起跑动作的力-时间特性使用安装在每个起跑块上的称重传感器进行评估。用激光系统记录短跑跑速度。全身振动组和对照组的等长和动态膝关节伸肌和膝关节屈肌力量未受影响（p > 0.05）。同时，膝关节伸展速度保持不变（p < 0.05）。启动动作的持续时间，由此产生的启动速度，启动加速度和冲刺跑步速度在两组中都没有改变（> 0.05）。总之，这种为期5周的全身振动方案在提高短跑运动员速度-力量表现的常规训练方案上没有剩余价值。
Despite the expanding use of Whole Body Vibration training among athletes, it is not known whether adding Whole Body Vibratil on training to the conventional training of sprint-trained athletes will improve speed-strength performance. Twenty experienced sprint-trained athletes (13 male, 7 female, 17-30 years old) were randomly assigned to a Whole Body Vibration group (n = 10: 6 male and 4 female) or a Control group (n = 10: 7 male, 3 female). During a 5-week experimental period all subjects continued their conventional training program, but the subjects of the Whole Body Vibration group additionally performed three times weekly a Whole Body Vibration training prior to their conventional training program. The Whole Body Vibration program consisted of unloaded static and dynamic leg exercises on a vibration platform (35 - 40 Hz, 1.7 - 2.5 mm, Power PlateO). Pre and post isometric and dynamic (100 degrees/s) knee-extensor and -flexor strength and knee-extension velocity at fixed resistances were measured by means of a motor-driven dynamometer (Rev 9000, Techno-gym (R)). Vertical jump performance was measured by means of a contact mat. Force-time characteristics of the start action were assessed using a load cell mounted on each starting block. Sprint running velocity was recorded by means of a laser system. Isometric and dynamic knee-extensor and knee-flexor strength were unaffected (p > 0.05) in the Whole Body Vibration group and the Control group. As well, knee-extension velocity remained unchanged (p > 0.05). The duration of the start action, the resulting start velocity, start acceleration, and sprint running velocity did not change (> 0.05) in either group. In conclusion, this specific Whole Body Vibration protocol of 5 weeks had no surplus value upon the conventional training program to improve speed-strength performance in sprint-trained athletes.
