A massive long-term study from Cleveland Clinic, published two days ago, shows that there is no such thing as too much exercise, and that too little exercise is a mortality risk factor greater than smoking or diabetes. The study followed 122,007 patients who underwent exercise treadmill testing at Cleveland Clinic between Jan. 1, 1991, and Dec. 31, 2014, to measure the association between aerobic fitness and mortality due to any cause.
The researchers found that there is a direct relationship between greater aerobic fitness and lower risk of mortality:
- The higher a person’s level of fitness, the lower their risk of dying, with very high levels of fitness having very strong positive effects for people over 70, and
- The lower a person’s level of fitness, the greater their risk of dying, with the most sedentary persons have a greater risk of mortality than the risks produced by coronary artery disease, smoking, or diabetes.
