Whole-body vibration (WBV) augments the musculoskeletal effects of resistance exercise (RE). However, its acute effects on bone turnover markers (BTM) have not been determined. This study examined BTM responses to acute high-intensity RE and high-intensity RE with WBV (WBV RE) in young women (n = 10) taking oral contraceptives in a randomized, crossover repeated measures design. WBV RE exposed subjects to 5 one-minute bouts of vibration (20 Hz, 3.38 peak-peak displacement, separated by 1 min of rest) before RE. Fasting blood samples were obtained before (Pre), immediately after WBV (PostVib), immediately after RE (IP), and 30-min after RE (P30). Bone alkaline phosphatase did not change at any time point. Tartrate-resistant acid phosphatase 5b significantly increased (p %26lt; 0.05) from the Pre to PostVib, then decreased from IP to P30 for both conditions. C-terminal telopeptide of type I collagen (CTX) significantly decreased (p %26lt; 0.05) from Pre to PostVib and from Pre to P30 only for WBV RE. WBV + RE showed a greater decrease in CTX than RE (-12.6% +/- 4.7% vs -1.13% +/- 3.5%). In conclusion, WBV was associated with acute decreases in CTX levels not elicited with RE alone in young women.
