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.
原发性衰老指健康和体能的逐渐衰退，取决于代谢率和氧化应激。继发性衰老的特征是身体成分和代谢功能的不利变化。我们假设运动和热量限制（CR）都能改善继发性衰老，但只有 CR 能改善原发性衰老。然而，CR 后进行运动是一种更好的策略，可以随着年龄的增长保持整体健康和生活质量。
