PURPOSE: The aim of this study was to investigate whether or not a single whole-body vibration treatment after eccentric exercise can reduce muscle soreness and enhance muscle recovery. SUBJECTS AND METHODS: Twenty untrained participants were randomly assigned to two groups: a vibration group (n = 10) and control group (n = 10). Participants performed eccentric quadriceps training of 4 sets of 5 repetitions at 120% 1RM, with 4 min rest between sets. After that, the vibration group received 3 sets of 1 min whole body vibration (12 Hz, 4 mm) with 30 s of passive recovery between sets. Serum creatine kinase, blood urea nitrogen, muscle soreness (visual analog scale) and muscle strength (peak isometric torque) were assessed. RESULTS: Creatine kinase was lower in the vibration group than in the control group at 24 h (200.2 +/- 8.2 versus 300.5 +/- 26.1 U/L) and at 48 h (175.2 +/- 12.5 versus 285.2 +/- 19.7 U/L) post-exercise. Muscle soreness decreased in vibration group compared to control group at 48 h post-exercise (34.1 +/- 11.4 versus 65.2 +/- 13.2 mm). CONCLUSION: Single whole-body vibration treatment after eccentric exercise reduced delayed onset muscle soreness but it did not affect muscle strength recovery.
