Abstract
Whole-body vibration (WBV) may potentiate vertical jump (VJ) performance via augmented muscular strength and motor function. The purpose of this study was to evaluate the effect of different rest intervals after WBV on VJ performance. Eight collegiately trained athletes (age 20.75 ± 1.16yr, mass 61.35 ±9.68kg, height 168.19±7.73cm) and eight recreationally active (age 22.25 ±1.83yr, mass 64.35 ±4.64kg, height 162.53 ± 2.6cm) individuals volunteered to participate in 4 testing visits separated by 24 hours. Visit 1 acted as a familiarization visit where subjects were introduced to the VJ and WBV protocols. Visits 2-4 contained 2 randomized conditions per visit with a 10-minute rest period between conditions. The WBV was administered on a multi-planar platform with a frequency of 30 Hz and an amplitude of 2-4 mm in 4 bouts of 30 seconds for a total of 2 minutes with 30 seconds of rest between bouts. During WBV, subjects performed a quarter squat every 5 seconds, simulating a countermovement jump (CMJ). Whole-body vibration was followed by 3 CMJs with 5 different rest intervals: immediate, 30 seconds, 1 minute, 2 minutes, or 4 minutes. For a control condition, subjects performed squats with no WBV. There were no significant (p > 0.05) differences in rate of force development after WBV rest intervals. However, results of VJ height revealed that maximum values, regardless of rest interval (19.250 ± 2.852 in), were significantly (p < 0.05) greater than the control condition (18.219 + 2.938 in). Therefore, subjects’ VJ height potentiated at different times after WBV suggesting strong individual differences in optimal rest interval. Coaches may use WBV to enhance acute VJ performance but should first identify each individual’s optimal rest time to maximize the potentiating effects.
