Abstract
We investigated the effects of capsaicin supplementation (150mg) on alterations of autonomic nervous system (ANS) activity associated with adverse effects of cardiac depolarization-repolarization intervals during aerobic exercise in obese humans. Nine obese males (26.1 [+ or -] 1.5 yrs) volunteered between study designed. The cardiac ANS activities evaluated by means of heart rate variability of power spectral analysis and cardiac QT interval were continuously measured during 5-min rest and 30-min exercise at 50% of maximal ventilation threshold (50%VTmax) on stationary ergometer with placebo (CON) or capsaicin (CAP) oral administration chosen at random. ...
