This review suggests moderate exercise may help keep muscle mitochondria working in a healthy balance.
Your muscle cells rely on a protein called Drp1 to keep their power plants (mitochondria) healthy. Too much or too little Drp1 causes muscle problems, and exercise seems to nudge it back into a healthy middle zone. In aging muscle this protein gets sluggish, while in diabetes it gets overactive, and moderate exercise may correct both directions.
