AIM: The aim of this study was to compare two recovery methods, control (CON) and lower-body vibration (LBV), on actual and perceived recovery, lower leg volume and sprint performance.
METHODS: Physically active female volunteers (n=12) participated in the study. In a counterbalanced design, participants completed a Yo-Yo intermittent test to volitional fatigue, 5 x 20-m sprints, recovery treatments on separate occasions, and post-recovery 5 x 20-m sprints to assess sprint performance. Rating of perceived exertion (RPE), heart rate (HR), and lower-leg volume were measured after fatiguing exercise, recovery treatment, and sprints.
RESULTS: No significant mean differences (p = 0.97) were found between CON and LBV regarding average of best three 20-m sprint times (3.85 ± 0.2 and 3.84 ± 0.25 s, respectively), or (p = 0.94) 10-m split times (2.22 ± 0.12 and 2.21 ± 0.15 s, respectively). However, a significantly better (p = 0.02) perceived recovery rating was observed after LBV (7 ± 2) compared to CON (5 ± 2). Post-recovery lower-leg volume was significantly higher than pre-treatment volume after LBV (p = 0.03) but not after CON (p = 0.07).
CONCLUSION: The current study shows that no benefits were observed for LBV in enhancing recovery or sprint performance.
