Adherence
Occupational physical activity, particularly light-intensity activity (LPA) and sedentary time (ST), does not confer the same cardiometabolic health benefits as leisure-time moderate-to-vigorous physical activity (MVPA), and high occupational ST is associated with adverse health outcomes regardless of leisure-time activity.
If you have a sedentary job, your health risk is driven by prolonged sitting, not just lack of exercise. If you have a physically demanding job, your health risk is driven by the lack of cardiovascular intensity and recovery time, not just 'activity.' To mitigate risk, office workers should prioritize leisure-time MVPA and reduce sitting time. Manual laborers should prioritize cardiovascular exercise and recovery, as their job activity may not provide sufficient health benefits and may even increase risk if not managed.
The 'physical activity paradox' suggests that PA undertaken at work differs in quality, quantity and health effects than PA performed during leisure-time... occupational PA carried out at lower intensities may not elicit substantial improvements in cardiorespiratory fitness... higher levels of occupational PA (even while controlling for leisure-time MVPA) are associated with an increased risk in premature mortality in men.
