| Research Abstract |
The purpose of this study was to reveal the effect of alteration inmetabolism of active muscle energy on the oxygen uptake during exercise. As a result, the Gibbs free energy in active muscle during exercise decreased, at the same time, oxygenuptake and activity level of active muscle derived from the surface EMG revealed significant increase. Also, compare with controlled condition, prior sever exercise does not effects the intramuscular energy release, however, activity level of muscle activitysignificantly increased. Therefore, these results suggest that increase of oxygen uptake and muscle recruitment were induced by the metabolic effects of (decrease of) intramuscular energy in high intensity exercise.
