Even Elderly Hearts Can Benefit From Exercise.
A pilot study involving 310 adults over age 70 found that even men and women in their later years can improve their heart’s health with moderate physical exercise. To assess the effect of exercise on the heart, researchers measured a blood-based injury marker called Troponin T that is traditionally used to assess damage to the heart. After one year, Troponin T levels in the exercise group were less than a third of the levels found in the control group that did not exercise. The study’s lead author, Dr. Christopher DeFilippi adds, “Our findings suggest biochemical evidence to support the old adage, ‘You’re never too old to start a physical activity program to improve cardiac health.'”
