Test period – University of Copenhagen

 

Test periode and schedule 

Test period

The test period was approximately 15 weeks, and the exercise intervention period lasted 12 weeks. During the test period, the diet and activity levels of the participants were periodically registered. They also had to meet regularly at the Faculty of Health Sciences, the Panum Institute.

Before and after the test period, there was 1 long day of tests at Copenhagen University Hospital, and 4 shorter test days at the University of Copenhagen's Department of Human Nutrition (Frederiksberg), the Panum Institute and Glostrup Hospital.

Test schedule

Test day 1 at the Panum Institute (approx. 4 hours): The participants fasted prior to their arrival. Their body composition was measured using DXA (dual-emission X-ray absorptiometry) scans, and their sugar metabolism was measured after they drank 75g of a sugar solution. Their fitness levels were also measured using a cycling test.

Test day 2 at the Panum Institute (approx. 3 hours): The participants fasted prior to their arrival. They cycled for 1 hour at 60% of their maximum performance level, and then rested for 1 hour.

Test day 3 at Copenhagen University Hospital (approx. 10 hours): The participants fasted prior to their arrival. Their sugar metabolism was measured, and they each had two muscle and fat biopsies taken. After this, the sugar metabolism of their muscles was measured using a low-dose PET-CT scan.

Test day 4 at the Department of Human Nutrition (approx. 4 hours): The participants fasted prior to their arrival, but were served a morning meal and a lunchtime meal. After this, they were provided with all of their food for the next 8 days.

Test day 5 at Glostrup Hospital (approx. 2 hours): The participants fasted prior to their arrival in the afternoon, and the amount of fat in their stomachs and thighs was determined using magnetic resonance imaging (MRI) scans.

The tests also included taking blood and tissue samples. At the end of the test period, the participants each received DKK 7.000 in remuneration for their involvement in the project.
