Key result
Endurance exercise improves myocardial function and aerobic energy metabolism versus sedentary controls in aging rats.
Why the study?
Does endurance exercise improve myocardial function and aerobic energy metabolism in aged male Sprague-Dawley rats?
Does endurance exercise improve myocardial function and aerobic energy metabolism in aged male Sprague-Dawley rats?
Endurance exercise training for 16 weeks improves myocardial function and aerobic energy metabolism in aged rats, though not fully restoring them to young levels.

Should not yet inform exercise prescriptions in the elderly; extends preclinical data on aged myocardial energetics.
Starnes et al. (1983) studied this question. Endurance exercise (running) vs. Sedentary animals (9- and 25-month-old) was evaluated on Myocardial function and aerobic energy metabolism. Endurance exercise training for 16 weeks in 25-month-old rats improved myocardial function and aerobic energy metabolism compared to age-matched sedentary controls.
