Outline of Final Research Achievements

"Bedridden" not only reduces the quality of life for the elderly, it causes an excessive burden on caregivers and a sharp increase in social security expenses. The cause of this bedridden is muscle atrophy / contracture. In collaboration with JAXA (Japan Aerospace Exploration Agency), we need to restore the function of mitochondria, a mechanosensor, to prevent atrophy and contracture of muscles. Continuing from the last fiscal year, this study demonstrates the effectiveness of a new rehabilitation method to elucidate the mechanism of muscle atrophy and muscle contracture caused by Unloading, such as weightlessness and bedridden, and intake of functional ingredients enabling mitochondrial function recovery did.
