Design outcomes

Primary

Measure	Time frame
1. Maximal oxygen uptake is measured at baseline, 3 months, 6 months, 12 months and 24 months using ergo spirometry measurement 2. Glycated heamoglobin (HbA1c) is measured at baseline, 3 months, 6 months, 12 months and 24 months from a blood sample	—

Secondary

Measure	Time frame
1. Fat oxidation rate is measured at baseline, 3 months, 6 months, 12 months and 24 months using indirect calorimetry 2. Body composition is measured at baseline, 3 months, 6 months, 12 months and 24 months using body fat caliper 3. Blood lipids is measured at baseline, 3 months, 6 months, 12 months and 24 months from a blood sample 4. Motivational effects is measured at baseline, 3 months and 24 months using the behavioural regulation in exercise questionnaire (BREQ), the Beck Depression Inventory (BDI) score, Subjective Vitality Scale (SVS) 5. Prevalence of genetic variables related to type 2 diabetes and training adaptations is determined from a single blood sample taken at 24 months 6. Socio-economical background and physical activity level during childhood is determined at 24 months using a questionnaire and interview	—
