Fitness warrants screening as a distinct CVD risk factor; extends meta-analyses by distinguishing its effects from those of physical activity.
Do the dose-response relationships between cardiovascular disease endpoints differ for leisure-time physical activity versus cardiorespiratory fitness?
Cardiorespiratory fitness and physical activity have distinct dose-response relationships with cardiovascular risk, suggesting fitness should be considered a separate risk factor worthy of screening.
