Abstract
Whole Body Vibration (WBV) causes increased blood flow and oxygen consumption, which contribute to free radical generation, yet levels of oxidative stress and antioxidant activity induced by WBV are unknown. This study compares oxidative stress of WBV with a known muscle-damaging protocol and metabolic equivalent exercise. Twenty-one untrained volunteer females (23.9 ± 1.0yr) were randomly allocated into one of three groups: Vibration training (WBV), Downhill Running (DHR) or Walking (WLK), and completed 8-weeks training of 3x20-min per week. Blood samples for Creatine Kinase, oxidative stress (F2-isoprostane), antioxidant enzyme activity of Glutathione Peroxidase (GPx) and Total Antioxidant Capacity (TAC) were collected at baseline, immediately following, and 24-hours after the first exercise session, and immediately following the final session. There was greater muscle damage in DHR (p = 0.02) compared with WBV and WLK at 24h post-exercise, but no difference between WLK and WBV. All groups showed increased F2-isoprostane levels immediately post-exercise (p < 0.05), but lower than baseline at 24-hours and 8 weeks. The WBV F2-isoprostane level changed the least and absolute levels were similar to WLK. There was a time main effect (p < 0.001) for GPx with activity greatest in DHR for acute and chronic responses. The TAC assay revealed immediate and 24hr post increases for DHR and WLK, but not WBV. An acute bout of WBV does not incur significant muscle damage, or oxidative stress, which could be advantageous to patient/elderly groups, but there is a GPx antioxidant training effect. Oxidative stress was highest immediately post-exercise, and WBV incurred the lowest percentage-change indicating its low damaging impact, and therefore safe use with vulnerable populations.
