Importance of Cardio Respiratory Fitness
In resent years, the scientific importance of measuring, estimating and monitoring cardio respiratory fitness has been increasing.
In 2016 the American Heart Association (AHA) made a scientific statement about the topic, in the article “Importance of Assessing Cardiorespiratory Fitness in Clinical Practice: A Case for Fitness as a Clinical Vital Sign. A Scientific Statement From the American Heart Association” by Ross et al. The article is available for free here.
According to the article:
“Mounting evidence has firmly established that low levels of cardiorespiratory fitness (CRF) are associated with a high risk of cardiovascular disease, all-cause mortality, and mortality rates attributable to various cancers. A growing body of epidemiological and clinical evidence demonstrates not only that CRF is a potentially stronger predictor of mortality than established risk factors such as smoking, hypertension, high cholesterol, and type 2 diabetes mellitus.”
And further recommends:
“At a minimum, all adults should have CRF estimated each year using a non-exercise algorithm during their annual healthcare examination. Clinicians may consider the use of submaximal exercise tests or field tests as alternatives because these involve individual-specific exercise responses.”
