Study Summary
The investigators propose in this project to determine the effect of 3 days of frequent interruption of prolonged sitting on metabolic health in healthy overweight sedentary adults (n=24), as compared to 3 days including a single long bout of isocaloric exercise or a control condition where subjects do not exercise but are subjected to prolonged sitting. The investigators believe that this proposed project will provide an initial evidence base for the health benefits of breaking up prolonged sitting with short bursts of moderate-intensity activity, like walking.
Primary Outcome
Total fat oxidation during the test day will be determined using whole-room indirect calorimetry. O2 consumption and CO2 production will be determined from the flow rates and differences in gas concentrations between air entering and air exiting the calorimeter as previously described
Interventions
- BEHAVIORAL Uninterrupted sitting
- BEHAVIORAL Sitting + 1 bout of activity
- BEHAVIORAL Sitting + microbursts of activity
