| Outline of Final Research Achievements |
The aim of this study was to elucidate metabolic regulatory system in terms of “inter- or extra- cellular lipid recruitment in working muscle”. In particular, based on the data obtained in non-invasive MRI measurements and molecular biologic study, we tried to investigate the energy metabolism during muscle contraction.
As a clue to advance our understanding of metabolic function of the skeletal muscle, which is significantly related to obesity and disorder of fat metabolism in today, we have focused on the difference of energy metabolism in upper and lower limbs, especially in the aspect of “evolution”(e.g., The morphological characters of the upper and lower limbs in humans could adapt differently over years after becoming bipedal), and fat metabolism in upper and lower limbs. As a result, we could obtain new findings in terms of “inter- or extra- cellular lipid recruitment in working muscle”.
