About this trial

This is an interventional basic science trial for Metabolic Health focused on measuring GLP-1, PYY, Breaking sitting, Energy balance, Postprandial glycaemia

Eligibility Criteria

20 Years - 45 Years (Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • Physical inactive males and females
  • Aged between 20 and 45 years
  • Overweight and obese healthy adults (waist circumference greater than 90 cm for males and 80 cm for females)
  • Weight stable for more than 3 months (no change in weight +/- 3%)

5. Study Description

Brief Summary
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.
Detailed Description
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.
