| Research Abstract |
The purpose of this study was to determine the effects of changes in muscle metabolites during leg pedaling exercise on force and surface electromyogram activity during subsequent maximal isometric elbow flexion. Exercise intensity during the leg pedaling exercise or oral administration of sodium bicarbonate 2 hours before the initiation of the leg pedaling exercise did not influence force and surface electromyogram activity during subsequent maximal isometric elbow flexion. Therefore, these results suggest that changes in muscle metabolites in active muscles induced by leg pedaling exercise do not act as afferent signals to modify efferent command from the central nervous system during subsequent maximal voluntary contraction in inactive muscles.
