| The main aim of this study is to investigate neural effect of using whole-body vibration (WBV) modality, as a non-fatiguing training stimulus (active recovery), metabolic performance (blood lactate) and heart rate responses during the inter-set rest period of hypertrophy based loading. Second to this, comparisons were also made between WBV effects versus traditionally use passive recovery method. Eight recreationally trained men were recruited for this study. Subjects randomly attended to testing sessions, where WBV modality was used during the inter-set rest period in one session and passive standing recovery was used in another session. In both sessions, subjects performed three sets of 10 repetition of squat exercise at 70% 1RM with 2 minutes inter-set rest period. Quadriceps and hamstring in-vivo muscle activation were assessed during the squat performance. The result of this study indicated that no significant differences were found between WBV active recoveries versus non-WBV passive recoveries in term of rate of muscle activation, blood lactate collection and heart rate responses. Thus, while WBV has been commercially promoted as an effective training tools, its effectiveness as an inter-set strength training active recovery tools was equivocal questionable. WBV application during the inter-set rest period did not promote muscle neural drive and it was similar with passive recovery in terms of muscle activation as it did not provide any additional stimulus that was expected. However, WBV as an inter-set recovery modality can be used as an alternative to passive recovery modality. |
