Nearly 60% of American children do not have healthy cardiorespiratory fitness (CRF), a key measure of physical fitness and overall health, according to “Cardiorespiratory Fitness in Youth – An Important Marker of Health,” a new Scientific Statement from the American Heart Association, published today in the Association’s flagship journal Circulation.
CRF, also referred to as aerobic fitness, refers to the body’s ability to supply oxygen to muscles during physical activity. Children with healthy CRF are more likely to live longer and be healthier as adults.
