| Popis: | Background Despite the increased use of whole body vibration among athletes, there is limited literature on its acute effects within heterogeneous populations such as untrained adults or recreational athletes. Hypothesis/Purpose The purpose of this study was to investigate the acute effects of whole body vibration on vertical jump, power, balance, and agility for untrained males and females. It was hypothesized that there would be an effect on each outcome variable. Study Design Quasi-experimental, pretest-posttest design. Methods Twenty males and sixteen females, mean age 24.5 years, were assessed for vertical jump height and power as measured by the Myotest accelerometer, balance as measured by the NeuroCom Balance Master System, and agility as measured by a modified T-test. Each session consisted of a five-minute treadmill warm-up, a practice test, a baseline measurement, a two-minute rest period, whole body vibration at 2 mm and 30 Hz for 60 seconds, and a final measurement. Three different counterbalanced testing sessions were separated by a minimum of 48 hours in between sessions to minimize fatigue. Results Significant differences existed for both genders for main effect of time for Agility (p = 0.022); end point excursion Left (p = 0.007); and maximum endpoint excursion Left (p = 0.039). Differences for main effect of gender revealed females performed better than males in the following respects: end point excursion Right (p = 0.035); end point excursion Left (p = 0.014); maximum endpoint excursion Right (p = 0.024); and maximum endpoint excursion Left (p = 0.005). Males performed better than females in two respects: Agility (p |
