The emergence of a method to quantify CRF began in the 1920s when Archibald Hill, a British physiologist, proposed a multifactorial relationship between the maximum rate of oxygen uptake by body tissues and intensity of physical activity. Regular physical activity and exercise can improve CRF, thus decreasing risk of CVD and other conditions while improving overall health. Some medical researchers claim that CRF is an even stronger predictor of mortality than smoking, hypertension, diabetes, or other commonly used risk factors. Low levels of CRF have been shown to increase the risk of cardiovascular disease (CVD) and all-cause mortality. ![]() In 2016, the American Heart Association published an official scientific statement advocating that CRF be categorized as a clinical vital sign and should be routinely assessed as part of clinical practice. As these body's functions are vital to an individual's health, CRF allows observers to quantify an individual's morbidity and mortality risk as a function of cardiorespiratory health. These functions include ventilation, perfusion, gas exchange, vasodilation, and delivery of oxygen to the body's tissues. Scientists and researchers use CRF to assess the functional capacity of the respiratory and cardiovascular systems. ![]() ![]() Cardiorespiratory fitness ( CRF) refers to the ability of the circulatory and respiratory systems to supply oxygen to skeletal muscles during sustained physical activity.
