Evaluating movement breaks as a public health strategy to mitigate the harms of prolonged sitting: a large-scale pragmatic intervention

This study investigates the effectiveness and feasibility of implementing brief, regular movement breaks as a public health strategy to counteract the negative effects of prolonged sitting. Conducted with over 19,000 adults, the findings indicate that movement breaks significantly improved psychosocial outcomes, such as reducing fatigue and enhancing positive affect, with hourly breaks providing the optimal balance between feasibility and effectiveness. The results support the potential of movement breaks as a viable intervention to mitigate the harms associated with sedentary behavior.
