Cardiorespiratory Fitness and Mortality Risk Across the Spectra of Age, Race, and Sex

Kokkinos et al. (Mon,) conducted a cohort in Cardiorespiratory fitness (n=750,302). Cardiorespiratory fitness (CRF) vs. Extremely fit individuals was evaluated on mortality (HR 4.09, 95% CI 3.90-4.20). Cardiorespiratory fitness was inversely associated with mortality, with the least fit individuals having a 4-fold higher risk (HR 4.09; 95% CI 3.90-4.20) compared to extremely fit individuals.
