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 lean adults.

Conditions

Metabolic Health; Gut Hormones; Energy Balance

Keywords

GLP-1; PYY; Breaking sitting; Energy balance; Postprandial glycaemia

Outcome Measures

Primary Outcomes (1)

• Gut hormones responses

  Changes in blood gut hormones responses (e.g., GLP-1, PYY and GIP concentrations measured in pmol/L) between trials

  320 minutes

Secondary Outcomes (7)

• Visual analogue scale (VAS)

  320 minutes

• Energy intake

  600 minutes after leaving the laboratory

• Physical activity level

  600 minutes after leaving the laboratory

• Lipid profile

  320 minutes

• Blood pressure

  320 minutes

Study Arms (2)

Prolonged sitting

EXPERIMENTAL

Participants sat on a chair during the trial.

Behavioral: Prolonged sitting

Breaking sitting

EXPERIMENTAL

Participants walked regularly during the trial.

Behavioral: Breaking sitting

Interventions

Prolonged sitting BEHAVIORAL

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.

Prolonged sitting

Breaking sitting BEHAVIORAL

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.
