Abstract

The purpose of this study is to investigate the effect of side-alternating whole body vibration (WBV) on hormone secretion and metabolism in healthy adults. Twenty voluntary participants (10 women) were recruited for the experiment to measure hormonal and metabolic responses to WBV (oscillation frequency, 26 Hz; amplitude, 1 mm; acceleration, 2.7 g) in blood samples drawn before, during and after WBV. WBV increased growth hormone serum levels in men and decreased them in women. Adrenocorticotropic hormone and cortisol decreased. Thyroid stimulating hormone, free T3, and free T4 decreased after WBV. Prolactin decreased in men. The secretion of gonadal hormones was not significantly influenced. Lactate levels increased during WBV and glucose levels decreased. Our results suggest that hormonal and metabolic responses to WBV do not simply reflect intensive exercising. The responses were characterized by a pattern of hormonal secretion typical for responses to mechanical vibrations of the whole body.
