Primary aging is the progressive decline in health and fitness and depends on metabolic rate and oxidative stress. Untoward changes in body composition and metabolic function characterize secondary aging. We hypothesize that both exercise and calorie restriction (CR) improve secondary aging, but only CR improves primary. However, CR followed with exercise is a superior strategy to maintain overall health and quality of life with age.
Calorie restriction yields greater improvements than exercise in determinants of lifespan by attenuating oxidative damage.
