Breaking Sitting and Metabolic Health in Sedentary Overweight and Obese Adults

Overview

The purpose of this project is to investigate the effects of breaking up prolonged sitting on postprandial metabolic responses, gut hormones secretion and energy balance in sedentary overweight and obese adults.

Two trials are included in this project - Prolonged sitting and Breaking sitting. In the Prolonged sitting trial, after consuming breakfast, participants sat on a chair for 180 min. After 180 min, lunch was provided. After finishing lunch, participants sat on a chair for another 120 min. In the Breaking sitting trial, after consuming breakfast, participants walked 2 min on a treadmill every 20 minutes for the following 180 min. For the remainder of the time participants sat on the chair. After 180 min, lunch was provided. After finishing lunch, participants continued 2 min of walking every 20 min for the following 120 min. Blood samples were collected in a regular pattern throughout the trials. Energy balance (e.g., energy intake and spontaneous physical activity) was assessed using food diary and an accelerometer until midnight in the trial days once participants left laboratory.
