Objective: Whole-body vibration (WBV) training has been established as a useful method to improve physical fitness in obese individuals. However, the effects of WBV exercise on maximal fat oxidation (MFO) have not been examined in obese subjects yet. Method: MFO was eval-uated during a cardiopulmonary exercise test (CPET) on a treadmill in 12 adult obese males (BMI = 34.9 ± 3.3 kg/m2) after three different warm-up conditions: static half squat plus WBV (HSV), static half squat without WBV (HSWV), and rest (REST). Cortisol levels were evaluated before and after the warm-up, and 1 min (T1), 10 min (T10), and 30 min (T30) of the recovery phase. Results: MFO was significantly higher in HSV (p = 0.013; 569.4 ± 117.9 mg/min) and HSWV (p = 0.033; 563.8 ± 142.9 mg/min) than REST (445.5 ± 117.9 mg/min). Cortisol concentrations at T1 were significantly higher in HSV (p = 0.023) and HSWV (p = 0.015) than REST. Moreover, cortisol concentrations were significantly lower at T30 than T1 in HSWV (p = 0.04). No differences were found between T30 and T1 in HSV. Conclusions: Active warm-up increases MFO; however, vibration stimulus during half squatting does not increase MFO during a CPET in obese subjects. The lack of significant differences of cortisol concentrations in HSV during the recovery phase might suggest a long-term effect of WBV on the endocrine system.

Abstract

Objective: Whole-body vibration (WBV) training has been established as a useful method to improve physical fitness in obese individuals. However, the effects of WBV exercise on maximal fat oxidation (MFO) have not been examined in obese subjects yet. Method: MFO was eval-uated during a cardiopulmonary exercise test (CPET) on a treadmill in 12 adult obese males (BMI = 34.9 ± 3.3 kg/m2) after three different warm-up conditions: static half squat plus WBV (HSV), static half squat without WBV (HSWV), and rest (REST). Cortisol levels were evaluated before and after the warm-up, and 1 min (T1), 10 min (T10), and 30 min (T30) of the recovery phase. Results: MFO was significantly higher in HSV (p = 0.013; 569.4 ± 117.9 mg/min) and HSWV (p = 0.033; 563.8 ± 142.9 mg/min) than REST (445.5 ± 117.9 mg/min). Cortisol concentrations at T1 were significantly higher in HSV (p = 0.023) and HSWV (p = 0.015) than REST. Moreover, cortisol concentrations were significantly lower at T30 than T1 in HSWV (p = 0.04). No differences were found between T30 and T1 in HSV. Conclusions: Active warm-up increases MFO; however, vibration stimulus during half squatting does not increase MFO during a CPET in obese subjects. The lack of significant differences of cortisol concentrations in HSV during the recovery phase might suggest a long-term effect of WBV on the endocrine system.
