NCT01430143

Brief Summary

The aim of the study is to 1) delineate the molecular mechanisms behind the large variation in insulin sensitivity among apparently healthy subjects and to 2) establish the dose-response relationship between physical training and a) metabolic health, b) appetite and c) cultural health.

Outcome Measures

Primary Outcomes (1)

  • Change from baseline in insulin sensitivity at 12 weeks

    As measured by a hyperinsulinemic, isoglycemic clamp combined with skeletal muscle and adipose tissue biopsies as well as low-dose PET/CT.

    At baseline and 12 weeks

Secondary Outcomes (4)

  • Change from baseline in body composition af 2, 6 and 12 weeks

    At baseline, 2, 6 and 12 weeks

  • Change from baseline in appetite at 12 weeks

    At baseline and 12 weeks

  • Motivational factors for exercise

    During and for up to 1½ year after the intervention

  • Diameter of t-tubuli in skeletal muscle

    At baseline
