Considerable data have emphasized the powerful impact of sedentary behavior, physical inactivity, and low levels of physical activity (PA) that result in poor levels of cardiorespiratory fitness (CRF) on overall and cardiovascular health.1-5 In fact, low PA and CRF may be the greatest threat to health in the 21st century. Therefore, greater efforts are needed throughout the health care system and at the government level to promote PA that improves CRF and contributes to reduced cardiovascular disease (CVD) and total mortality worldwide.
