Stand More, Sit Less, For Better Metabolic Health, Jehu N. Apaflo Feb 2023

Stand More, Sit Less, For Better Metabolic Health, Jehu N. Apaflo

International Journal of Exercise Science: Conference Proceedings

Sedentary behaviors are associated with metabolic risks such as weight gain, high adiposity, and abdominal/visceral fat deposition. The American College of Sports Medicine recommends a minimum of 150 mins per week of moderate to vigorous physical activity for health benefits. Adherence, however, is poor due to the prolonged sitting hours required for most modern jobs and the excessive television viewing habits. Emerging studies show that interrupting long sitting hours with intermitted breaks of light activities attenuates the pernicious effects of sedentariness. While most studies and policy guidelines focus on physical activity interventions, there is a lack of data on the …
