Breaking Up Prolonged Sitting on Metabolic Flexibility

“Effect of Breaking up Prolonged Sitting on Metabolic Flexibility”
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.

Behavioral - Uninterrupted sitting
Subjects will be asked to refrain for two days from any structured activity and to reduce any daily life activity (walking, taking the stairs, biking, etc.) in their daily life. On day 3, subjects will remain seated all day in the room calorimeter, except to rise from the chair to void.
Behavioral - Sitting + 1 bout of activity
Subjects will be asked to perform 45 minutes of moderate-exercise in the morning once per day for two days in their daily life. On day 3 they will remain seated all day in the room calorimeter, except to rise from the chair to void, and to perform one bout of 45-min moderate-intensity (defined below) walking on a treadmill at 1000.
Behavioral - Sitting + microbursts of activity
Subjects will be asked to refrain from any structured exercise for two days but to walk for 5 minutes each hour between 1000 and 1800 in daily life. On day 3, subjects will rise from the seated position every hour for 9 hours from 1000 to 1800 to complete 5min moderate-intensity (defined below) walking on a treadmill, which represents a total of 45min.
