Association of Cardiorespiratory Fitness With Long-term Mortality Among Adults Undergoing Exercise Treadmill Testing. JAMA Network Open, 2018; 1 (6): e183605 DOI: 10.1001/jamanetworkopen.2018.3605

Elite performers had an 80% reduction in mortality risk when compared to lower performers. Cleveland Clinic researchers have found that better cardiorespiratory fitness leads to longer life, with no limit to the benefit of aerobic fitness.

Researchers retrospectively studied 122,007 patients who underwent exercise treadmill testing at Cleveland Clinic between Jan. 1, 1991, and Dec. 31, 2014, to measure all-cause mortality relating to the benefits of exercise and fitness. The paper was published today in the Journal of the American Medical Association Network Open.

Just 1 minute of intense exercise produces significant health benefits. The findings put to rest the common excuse for not getting in shape: there is not enough time. “This is a very time-efficient workout strategy,” says Martin Gibala, a professor of kinesiology at McMaster. “Brief bursts of intense exercise are remarkably effective.”

Scientists set out to determine how sprint interval training (SIT) compared to moderate-intensity continuous training (MICT), as recommended in public health guidelines. They examined key health indicators including cardiorespiratory fitness and insulin sensitivity, a measure of how the body regulates blood sugar.
