This book was released on 2016 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than 30 years, researchers have investigated the effects of whole body vibration (WBV) platforms on athletic performance. WBV is a modality in which an individual stands on a vibrating platform to obtain performance effects. Frequency and amplitude of the vibration are the commonly adjusted parameters. The use of WBV as a modality for athletes has gained traction in response to emerging evidence demonstrating significant gains in performance measures including increased jump height and muscular strength. Collective results from several studies suggest a single vibration frequency, optimal vibration frequency (OVF), exists which elicits the greatest effect on performance. However, due to large variations in methodology it remains unknown if an OVF exists and, even more importantly, how OVF for individual athletes should be determined and utilized. There is a need to further identify how various parameters (i.e., frequency or exposure time) impact OVF as a means of enhancing our understanding and utilization of OVF on performance outcomes. The purpose of this study was to determine the WBV frequency that optimizes knee extensor torque and countermovement jump height in physically active adults between 18 and 40 years of age. The central hypothesis was that a single WBV frequency (35 Hz) for optimizing knee extensor torque (KET) and countermovement jump height (CMJ) would be identified. A comparison of KET and CMJ across 1) three independently delivered whole body vibration frequencies and 2) determined if one frequency was associated with greater KET and CMJ to a greater extent than the other frequencies and a control condition. I hypothesized that one of the WBV frequencies would result in greater KET and CMJ when compared to the other frequencies and a control. Additionally, I analyzed the distribution of an individual participants increase in KET and CMJ across three different WBV frequencies. I hypothesized that a greater number of participants would exhibit a larger increase in KET and CMJ after a 60 second exposure of whole body vibration at 35 Hz. Twenty-six recreationally active adults performed pre and posttest isometric KET and CMJ after a 60 second exposure of WBV at a specific frequency. From recorded KET and CMJ height, the largest value from the trials were calculated. There were no changes in KET or CMJ after WBV treatments when compared to pretest and control values. The results suggest that a 60 second exposure of WBV has no effect on maximal KET or CMJ when coupled with a 2-hour rest period. It could be suggested that the compounding of multiple frequencies and increased exposure time within a short time period could produce an effect. To better understand if WBV affects performance, incrementally increasing exposure length with a washout period and a signal that accounts for all frequencies at once warrants being studied.

Download or read book Acute Effects of Whole Body Vibration on 30 Meter Fly Sprint Performance in NCAA Division I Sprinters and Jumpers written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to identify a potentiation effect on 30 meter (m) fly sprint performance in collegiate sprinters and jumpers (M=21, W=5) following an acute bout of whole-body vibration. The WBV protocol consisted of one 30 second bout at 50 Hz, ~3 mm amplitude, and 60 seconds rest before a 30m fly sprint. Sprint times were measured using timing gates, and characteristics of strength and power were measured using a force plate. Analysis included measures of jump height, peak power, peak force, and rate of force development. Each subject participated in 3 separate trials using randomized treatment sessions over 3 months of preparation training. The control condition consisted of no vibration and WBV treatment 1 and 2 incorporated vibration. Statistics comparing the average sprint times showed no treatment effects. The results of this study indicate that WBV at 50 Hz and ~3 mm amplitude has no effect on sprint times.

This book was released on 2005 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to determine the effects of whole-body vibration on electromechanical delay and vertical jump performance. Twenty college aged subjects participated in 10 intervals of whole-body vibration (WBV) at a frequency of 26 Hz and amplitude of 5 mm. Each interval consisted of 60 s of WBV in a half-squat followed by 60 s of rest. After 5 intervals, subjects had 6 min of rest before the final 5 intervals. Each subject also participated in the control which included the same 10 intervals in a half-squat without the WBV. Tests were conducted to assess electromechanical delay (EMD) and vertical jump at baseline, during the 6 min rest period and immediately after the treatment and control. EMD was measured using tibial nerve stimulation and a force plate. EMD was recorded as the lag time between the initiation of gastrocnemeus stimulation and plantar flexion force production. Vertical jump was measured using a force plate and subjects2 flight time. The factorial ANOVA results showed no differences between groups, the control and WBV treatment, for both EMD (F (2, 38) = 1.385, p = 0.263) and vertical jump (F (2, 38) = 0.040, p

This book was released on 2013 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The present study was designed to examine the acute effects of unstable surface training (UST) and whole body vibration (WBV) on countermovement (CMJ) and squat jump (SJ) performance in NCAA Division III college female athletes. Subjects consisted of 20 female athletes currently performing strength and conditioning programs. Subjects random-ly completed 6 sessions of 20 body wt squats to tempo in one of three conditions (CON r UST r or WBV) followed by 4 min passive rest and three each of the CMJs and SJs. Testing was performed on non-consecutive days. Subjects were assessed for jump height (JH) r max force (F) r rate-offorce development (RFD)r max power (P) r and vertical takeoff velocity (V). Post testing r the CMJ and SJ in each condition were analyzed for eccentric utilization ratio (EUR). There was no significant interaction in the current study (p > .05) There were no significant main effects for condition (p > .05). Significant main effects (p .05) were found for JHr RFDr P r and V for jump type (CMJ SJ) In Division III female athletes UST and WBV did not improve performance on the CMJ or SJ. On an acute basis r the use of UST or WBV was not shown to be beneficial for increasing Fr RFDr P r Vr or for improving the EUR.

This book was released on 2010 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The purpose of this study was to monitor the acute effect of a hip flexors stretch on vertical jump performance in NCAA Division II track and field athletes. The subjects who volunteered for this study were members of Bemidji State University men's and women's NCAA Division II track and field team with a mean age of 20.74 years. Subjects performed vertical jumps following a warm-up with and without a stretching routine. The stretching routine was a lunging hip flexors stretch held for two sets of 30 seconds for each leg. A General Linear Model (GLM) with repeated measure was used to determine significant interaction between routines and gender as well as a main effect for rountine. Results indicated no significant interaction between stretching and gender F(1,23)=2.048, p=0.167, and no main effect for stretching (M=113.91) and non-stretching (M=114.09) protocols for vertical jump, F(1,23=0.335, p=0.569. Results suggest that a static stretch of the hip flexors has no effect on vertical jump height on either gender"--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: "Vertical jump height is a method of assessing muscle strength and power in the lower body, and is used to assess athletic ability. The gold standard in measuring vertical jump height is the measurement of the vertical centre of mass (COM) displacement from three-dimensional (3D) video analysis. Vertical jump height is ultimately affected by takeoff COM velocity, as greater takeoff velocity results in greater jump height. The current study explored the use of takeoff versus maximum COM velocity by examining the relationships and differences between 3D video analysis and 3D force platform analysis when predicting vertical COM displacement. Use of the Vertec, and correction of takeoff COM velocity using takeoff posiion, was explored through methods proposed by Aragon-Vargas (2000) and Moir (2008)."--from abstract.
