The purpose of this study was to investigate the effect of sports drinks on respiratory quotient (RQ) during moderate exercise, Six young male subjects (aged 20 yr) participated in this study, after the informed consent was obtained from all subjects. Subjects performed a maximal test and four exercises at 50% of maximal oxygen uptake (VO[2]max) using a bicycle ergometer. During exercise tests VO[2], carbon dioxide excretion and RQ were measured by the respiratory gas analyzer. Subjects randomly drunk water or three sports drinks (Pocarisweat, VAAM, Gatorade) (200 ml) before 10 min at the beginning of each exercise, then exercised at 50% VO[2]max for 20min. At rest VO[2] and RQ were 3.6±0.4 ml/kg/min and 0.90±0.09, respectively. VO[2] increased 1.6±3.8 ml/kg/min at 20 min exercise (p<0.001). RQ during exercise was not statistically different from at rest. The differences in VO[2] and RQ among four drinks were not found. These results suggest that VO[2] and RQ during exercise is not extended by the intake of sports drinks.
