Acute effects of whole body vibration and vertical jump height

Abstract

The purpose of this study is to test vertical jump height after performing
different warm up routines including jogging on a treadmill, riding a stationary bike,
static stretching, and standing on a VibePlate. It was hypothesized that there would be a
significant increase in vertical jump height after warming up on the VibePlate versus
other warm up modalities. The participants for this study were Eastern Illinois University
undergraduate and graduate students age 18-24 years (20.85 ± 1.70 yrs.). The sample
consisted of sixteen men and ten women who were classified as low risk after
completion of the PAR-Q. All participants signed an informed consent prior to data
collection. Subjects were tested for vertical jump height (cm) immediately following
warm-up and at 15 and 20 minutes post warm-up. One testing session was completed
per week with the order of warm-up methods randomized. Measurements were taking
by using a Vertec Device (Vertec Sports Imports, Hillard, Ohio). All Data was analyzed
using SPSS Version 16.0 using a 3x4 repeated measures ANOVA to compare the vertical
jump height. An Alpha level of 0.05 was used to determine significance.
No significant difference in vertical jump height between time points within each
warm up method. There was a significant difference within each time point between
warm up methods. Vertical jump height assessed immediately after warm-up was
significantly greater for the Vibeplate versus the bike (p = 0.002) and the vibeplate
versus static stretching (p = 0.0001). Vertical jump height assessed 15 minutes following
warm-up was significantly greater for the vibeplate versus the bike (p = 0.007), the
vibeplate versus static stretching (p = 0.004), and the vibeplate versus the treadmill (p =
0.001). Vertical jump height assessed 20 minutes following warm-up was significantly
greater for the vibeplate versus the treadmill (p = 0.005).
