Outline of Final Research Achievements

The purpose of this study is to investigate the relationship between change in muscle glycogen levels and body water status measured by bioimepdance spectroscopy (BIS). We suggested that increase in body water accompanied by muscle glycogen supercompensation can be detected using BIS, owing to segment specific increase in intracellular water. These results imply that monitoring the change in segmental intracellular water using BIS may contribute to an understanding of the muscle glycogen levels.
