Research published recently in the National Academy of Sciences indicates just that. The study focused on mice that were genetically programmed to age faster than normal. Then, some of the mice exercised (treadmill) and the others were inactive. 5 months later, the mice who exercised were still young and their organs and brains functioned normally. By comparison, the sedentary mice had begun to age, go bald, were less active and had weakened organs. If you like details, it came down to the mitochondria (power center of cells that generates energy) and the exercising mice had fewer signs of damage to their mitochondria. Very interesting…
