Abstract

The purpose was to examine the effects on strength and power of progressive-overload, whole body vibration (WBV) training as part of a 15-week periodized, strength training (ST) program. Eighteen collegiate women athletes with >= 1 year of ST and no prior WBV training participated in the crossover design. Random assignment to one of two groups followed pre-tests of seated medicine ball throw (SMBT), single leg hop for distance (LSLH, RSLH), countermovement jump (CMJ), 3-RM front squat (FS), pull-up (PU), and 3-RM bench press (BP). WBV was two 3-wk phases of dynamic and static-hold bodyweight exercises administered 2 days/wk in ST sessions throughout the 15-wk off-season program. Total WBV exposure was 6 min broken into 30-sec bouts with 60-sec rest (1:2 work relief ratio). Exercises, frequency and amplitude progressed in intensity from the first 3-wk WBV training to the second 3-wk phase. Repeated measures ANOVAs were used to analyze the SMBT, CMJ, LSLH, RSLH, FS, PU, and BP tests. Alpha level was p<0.05. FS, LSLH, and RSLH increased (p=0.001) from pre- to post- test. FS increased from mid- to post- test. PU increased (p=0.008) from pre- to post- test. SMBT and BP showed a trend of increased performance from pre- to post test (p=0.11). Two 3-week phases of periodized, progressive-overload WBV+ST training elicited gains in strength and power during a 15-wk off-season program. Greatest improvements in performance tests occurred in the initial WBV phase. Implementing WBV in conjunction with ST appears to be more effective in the early phases of training.
