Global status of cardiorespiratory fitness and physical activity - Are we improving or getting worse?

Despite heightened recognition of the importance of cardiorespiratory fitness (CRF) to cardiovascular (CV) health, along with updated international consensus guidelines for physical activity (PA) and sedentary behavior (SB), significant proportions of the global adult population are physically inactive, and do not meet the threshold for CRF. Physical inactivity is considered a surrogate for low CRF given that the former is defined as not reaching the recommended minimum level of PA per week to derive a health benefit. Physical inactivity remains a major global public health problem despite decades of work by various United Nations agencies, and members of the international community to improve PA levels. Given the common coupling between physical inactivity and poor health status, it is reasonable to suggest that for a significant proportion of the global population, CRF is compromised by physical inactivity. This poses a longer-term risk to morbidity and mortality. Here we provide an indicative summary of the global status of CRF and PA and reference the implications for global health. We briefly reference opportunities moving forward, including reinforcement of the importance of engaging in movement from an early age, discouraging SB, and taking a life course approach to optimise healthy living for all.
