Abstract:The purpose of this study was to investigate the effects of whole body vibration (WBV) accompanied by static stretching as a recovery method on delayed onset of muscle soreness (DOMS) after eccentric exercise in male subjects. Thirty-six trained male university students were participated in this study. The maximal heart rate, visual analogue scale (VAS), range of motion (ROM), serum lactate dehydrogenase (LDH) and creatine kinase (CK) of the participants were measured prior to the experiment. All participants were randomly assigned into vibration training (VT, n = 12), static stretching (SE, n = 12) or control (CON, n = 12) groups. On Day 1 of this study, all participants were asked to perform an eccentric exercise (85% heart rate reserve downhill running for 30 min). Then, the VT group performed WBV and static stretching (50 Hz, 1.5 mm, 3 × 60 s, 3 exercises) and the SE group performed static stretching (3 × 60 s, 3 exercises). On Days 2-4, the VAS, ROM, LDH and CK of all participants, including control subjects were measured. The CK and LDH concentrations of the VT group were significantly lower than those of the SE and CON groups, but no significant difference was observed between SE and CON groups. In addition, VAS and ROM of the VT group were significantly improved. The results suggested that WBV accompanied by static stretching can promote the recovery from muscle damage after eccentric exercise, and the improvement in the DOMS recovery rate in VT group was more satisfactory than that of SE group.
