Cardiorespiratory fitness is a crucial predictor of morbidity and mortality among adults, as evidenced by over 20.9 million observations from 199 cohort studies. High levels of cardiorespiratory fitness are associated with a significantly lower risk of all-cause mortality, cardiovascular disease, and incident chronic conditions. Notably, a one-MET increase in CRF was linked to an 11%-17% reduction in all-cause mortality, and an 18% reduction in heart failure risk. Importantly, the evidence supports incorporating CRF as a vital sign in clinical practice for improved risk stratification. Further research is needed to explore CRF’s impact on specific health outcomes and neglected populations like women and certain clinical groups.
