RESUMO
Whole body vibration (WBV) has been recognized as an effective alternative exercise modality to resistance exercise for its ability in enhancing force and power, generating capacity in skeletal muscle, increasing bone mass and improving cardiovascular function. Since the effect of WBV exercises on growth hormone (GH) levels has been never compared and discussed, the aim of this study was to review systematically the literature to verify the WBV effects on GH concentration. By using PubMed, Scopus and PEDRo databases with the keywords 'growth hormone' or GH and 'whole body vibration' or WBV, we found and analysed 12 papers (182 subjects recruited), verifying their level of evidence (National Health and Medical Research Council hierarchy of evidence) and the methodological quality (PEDRo scale). Although WBV induced GH responses in nine out of 12 publications, caution should be however taken when considering the results due to the markedly different methodologies among these publications.
