The impact of moving more, physical activity, and cardiorespiratory fitness: Why we should strive to measure and improve fitness?

A large and growing body of epidemiologic research spanning roughly 7 decades has demonstrated that individuals who are more physically active have a lower incidence of cardiovascular disease (CVD) and all-cause mortality compared to those who are comparatively sedentary. Despite these well-established benefits of physical activity (PA), most adults and children do not get an adequate amount of PA. This is true not just in the United States but has been increasingly recognized throughout advanced countries. The theme of this Progress in Cardiovascular Diseases Symposium is moving more, recognizing that any amount of increased physical movement, including occupational, recreational, household tasks, etc., has significant health benefits. Being physically active is associated with better health outcomes independent of cardiorespiratory fitness (CRF), a concept that would have been considered heretical a few decades ago. We now recognize that simply moving from a sedentary to a moderately active group or modest increases in CRF (e.g. moving from the least fit quintile of CRF to the next least fit quintile) has the most noticeable health benefits. In this review, the concept of moving more and its implications for CRF are discussed as they relate to the prevention and treatment of CVD. (c) 2020 Elsevier Inc. All rights reserved.

Automated summary

Regular physical activity is associated with lower incidence of cardiovascular disease and all-cause mortality. Despite the well-established benefits, most adults and children do not engage in adequate levels of physical activity. Any increase in physical movement, whether from work, leisure, or household tasks, can have significant health benefits.
