Cardiovascular Fitness and Longevity
Experts say there is no downside to high fitness levels.
Extremely fit patients live longer than less fit peers, according to research conducted at the Cleveland Clinic in Ohio. “We found in our study there is no limit in how much exercise is too much,” said principal investigator Wael Jaber, MD, Cleveland Clinic cardiologist. “Everyone should be encouraged to achieve and maintain high fitness levels.” The study’s purpose was to examine the relationship between high fitness levels and longevity as compared with more modest levels of cardiovascular fitness.
Researchers analyzed data from over 122,000 patients, who had taken exercise treadmill tests between 1991 and 2014, to measure risk of death from any cause and its relationship to fitness levels and exercise. Higher cardiorespiratory fitness levels were directly associated with longer life. Extreme cardiovascular fitness carried the most
benefit, especially for patients aged 70 and older and those with hypertension. Study authors noted that healthcare professionals should encourage patients to maintain high fitness levels for optimal health.
