Outline of Final Research Achievements

The aim of present study was to investigate whether extension of exercise time associated with glycogen-loading influence on recovery process after muscle fatigue. As the result of performing glycogen-loading to rat, both muscle glycogen content and fatigue resistance increases, but there were no effect on both tetanic tension and function of sarcoplasmic reticulum in recovery process from fatigue. Therefore, it was suggested that glycogen-loading has no effect on recovery process after muscle fatigue.
