Cleveland Clinic researchers have established that better cardio-respiratory fitness leads to longer life, with no limit to the benefit of aerobic fitness. They retrospectively studied 122,007 patients who undertook exercise treadmill testing at Cleveland Clinic between Jan. 1, 1991, and Dec. 31, 2014, to measure all-cause mortality linking to the benefits of exercise and fitness.
The study found that better cardio respiratory fitness was directly connected with lessened long-term mortality, with no limit on the positive effects of aerobic fitness. Extreme aerobic fitness was allied with the highest benefit, chiefly in older patients (70 and older) and in those with hypertension.
The risk associated with poor cardio respiratory fitness was similar to or even outdid that of traditional medical risk factors, such as cardiovascular disease, diabetes and smoking.
The study's findings highlight the long-term benefits of exercise and fitness, even to extreme levels, irrespective of age or concurrent cardiovascular disease.
