Improvement in running economy after 8 weeks of whole-body vibration training. J Strength Cond Res 26(12): 3349-3357, 2012-The purpose of this study was to investigate the effects of 8-week whole-body vibration (WBV) training on running economy (RE) and power performance. Twenty-four male collegiate athletes were recruited and randomly assigned to experimental (WBV) and placebo (PL) groups. TheWBV subjects performed semisquat vibration training (30 Hz, ±122 mm, 3 times per week), whereas PL subjects performed identical training without vibration. The isometric maximum voluntary contraction tests were used to evaluatemaximal isometric force (Fmax) and rate of force development (RFD) of lower extremities, before and after the intervention, and RE was measured on a level treadmill at 3 velocities (2.68, 3.13, and 3.58 m.s-1). The Fmax of the lower leg (plantar flexion, from 80.8 ± 24.5 to 99.0 ± 33.9 N.m, p < 0.05, h2 = 0.567; dorsiflexion, from 38.1 ± 6.5 to 43.0 ± 7.7 N.m, p < 0.05), and the RFD of 0-200 milliseconds during plantar flexion (from 186.0 6 ±9.2 to 264.6 ± 87.2 N.m.s-1, p , 0.05, h2 = 0.184) were significantly increased in the WBV group after training. The averaged RE values for the 3 running velocities were significantly improved after WBV training (pretraining vs. posttraining, 4.31 6 0.33 vs. 4.65 6 0.34 m.ml21.kg -1, p = 0.001, h2 = 0.654); however, no significant differences were found in the PL group (pretraining vs. posttraining, 4.18 ± 0.26 vs. 4.26 6 0.44 m.ml21.kg-1, p = 0.476). The WBV training significantly improved RE at selected speeds (5.028.5%, p 7< 0.05). These results indicated that short-term WBV training could be an effective stimulus to enhance RE and lower extremity power performance in competitive athletes.
