Although public-health recommendations to engage in moderate-to-vigorous physical activity (at least 30min, 5 days / week) have been widely promulgated by the government, most people are physically inactive. Sedentary behaviors, like time spent sitting, are associated with serious implications on metabolic health, indicating that even in individuals who regularly exercise a reduction in time spent sitting can confer health benefits. Our work tests the effect of frequent interruptions of prolonged sitting by microbursts of activity, an intervention likely easier to implement in daily life of at-risk population, on overall well-being, mood, energy level, appetite and metabolic health. We are using an approach of integrative physiology from the whole-body level to cell, protein and genes to understand the biological mechanisms that underlie associations of frequent interruptions of prolonged sitting with improved metabolic health outcomes. We believe that breaking up prolonged sitting with short bursts of activity is an innovative strategy that can be more effective at combating the adverse effects of sedentary behaviors than more traditional approaches.
