The research here notes an aspect of mitochondrial biochemistry that declines with age in a way that appears unaffected by fitness and exercise. One of the challenges inherent in investigating the mechanisms of aging in muscle tissue is determining the difference between decline due to disuse (secondary aging) versus decline due to intrinsic processes of damage accumulation (primary aging). We live in a world in which being older tends to mean being wealthier, with greater access to transportation and calories. Near all older adults fail to maintain a good program of exercise and diet, and the difference between those who make the effort to remain fit and slim and those who do not is sizable. That much is demonstrated by the significant gains in cardiovascular health and muscle strength that can be achieved in the elderly through structured exercise programs. So it is interesting to see research results in which the data makes it very clear that a specific measure of aging in muscle tissue is independent of exercise.
