Longitudinal Algorithms to Estimate Cardiorespiratory Fitness

This study sought to determine the capacity of cardiorespiratory fitness (CRF) algorithms without exercise testing to predict the risk for nonfatal cardiovascular disease (CVD) events and disease-specific mortality.Cardiorespiratory fitness (CRF) is not routinely measured, as it requires trained personnel and specialized equipment.Participants were 43,356 adults (21% women) from the Aerobics Center Longitudinal Study, followed up between 1974...
