The IDLE Breaks study

Are you overweight and sit for long periods of time?

Baker IDI Heart and Diabetes Institute is currently examining whether reducing sedentary behaviour (prolonged sitting time) can help improve blood glucose and blood fat levels in older, overweight adults.

There is emerging evidence that people who break up their sitting time with activity breaks (such as light walking) may have better blood glucose and blood fat levels than people who sit for prolonged periods without activity breaks.

What’s involved

This study aims to test the effects of a single bout (7hrs) of prolonged sitting on blood glucose and blood fat levels, with and without intermittent bouts of light-intensity or moderate-intensity activity.

Study Summary

Participants will be required to: Attend up to 5 visits (including three 7hr visits) over a four week period Walk at a slow (3.2km/hr) and a brisk (6.4km/hr) pace on a motorised treadmill Provide blood samples at regular intervals (using an intravenous catheter) during the 7hr testing procedure Consume meals specifically prepared by a research kitchen Have muscle and fat biopsies (optional)

Who can participate

Eligible participants must be aged between 45 and 65 years and not be on glucose or cholesterol (lipid) lowering medications
