Individualized Whole-Body Vibration: Neuromuscular, Biochemical, Muscle Damage and Inflammatory Acute Responses

Abstract

Objective. We aimed to investigate the acute residual hormonal, biochemical, and neuromuscular responses to a single session of individualized whole-body vibration (WBV) while maintaining a half-squat position. Methods. Twenty male sport science students voluntarily participated in the present study and were randomly assigned to an individualized WBV group (with the acceleration load determined for each participant) or an isometric group (ISOM). A double-blind, controlled parallel study design with repeated measures was employed. Results. Testosterone and growth hormone increased significantly over time in the WBV group ( P < .05 and P < .01, respectively; effect size [ES] ranged from 1.00 to 1.23), whereas cortisol increased over time in both groups ( P < .01; ES ranged from 1.04 and 1.36). Interleukin-6 and creatine kinase increased significantly over time only in the WBV group ( P < .05; ES = 1.07). The maximal voluntary contraction decreased significantly over time in the ISOM group ( P = .019; ES = 0.42), whereas in the WBV group, the decrease did not reach a significant level ( P = .05). The ratio of electromyographic activity and power decreased significantly over time in the WBV group ( P < .01; ES ranged from 0.57 to 0.72). Conclusion. Individualized WBV increased serum hormonal concentrations, muscle damage, and inflammation to levels similar to those induced by resistance training and hypertrophy exercises.

Evaluation of the Efficacy of Supplementation with Planox® Lemon Verbena Extract in Improving Oxidative Stress and Muscle Damage: A Double-Blind Controlled Trial

“…Each participant repeated the test 3 times, and CMJ data were obtained at the designated points. The instrument was calibrated for each individual's weight 27 . In this study, this assessment was performed before and 24 and 48h after the exhaustive exercise program.…”

Inflammatory Biomarker Responses to Whole-Body Vibration in Subjects with Different Clinical Status: A Systematic Review

“…The selected studies included several populations with different clinical status. One publication analyzed the effects of WBV exercises on knee osteoarthritis [ 40 ], one in healthy elderly individuals [ 19 ], one in young male students [ 41 ], and one in obese individuals [ 42 ]. All of the studies aimed to investigate IBR after WBV intervention.…”

“…Almost all of the selected studies used vertical VP, except for one [ 41 ], which did not specify the VP movement. The frequency and peak-to-peak displacement (D) of the mechanical vibrations ranged from 12 to 50 Hz and from 2 to 4 mm, respectively, and one publication [ 41 ] did not specify the D in mm.…”

One study [ 41 ] investigated the acute effects of WBV exercise, while three studies [ 19 , 40 , 42 ] examined the long-term effects of WBV protocols.…”

Acute effects of whole body vibration exercise on post-load glucose metabolism in healthy men: a pilot randomized crossover trial

“…Fifth, the effect of unmeasured endocrine hormones remained unclear. Some studies examined testosterone, insulin-like growth factor 1 levels after WBVE [ 24 , 36 , 37 ], which might contribute to post-load glucose metabolism after WBVE. Future studies will be needed to validate the current findings.…”
