Design outcomes

Primary

Measure	Time frame
Aerobic fitness was tested using a graded test on a cycle ergometer (Monark 874 E, Monark Exercise AB, Vansbro, Sweden). The starting load was 70 W with a cadence of 70 revolutions per minute (RPM). Every minute the resistance was increased by 35 W until the subject was exhausted (cadence <65 RPM). Oxygen uptake was measured continuously with a Cosmed K4b2 breath by a breath metabolism analyser (Cosmed Srl, Rome, Italy) and was calculated from the highest 30 s averaging interval at the conclusion of the test.	—

Secondary

Measure	Time frame
1. Blood pressure and resting heart rate (RHR) were measured on the left arm after five minutes of rest. The measurements were taken three times in intervals of one minute. The average of the last two measurements of both the systolic (sBP) and the diastolic pressure (dBP) was used in the statistical analysis. Blood pressure and RHR was measured with BpTRU® (Bp TRU medical devices, Coquitlam, Canada) on both occasions. All tests were performed using the same device and by the same researchers at the same time of the day both at baseline registration and at follow-up. 2. Glycosylated hemoglobin (HbA1c) was collected in EDTA blood. Serum for investigation of lipids (cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL) and C-reactive protein (CRP) was collected on gel tubes and then centrifuged 35 x 1000 rpm for 15 minutes within 60 minutes after the blood had been drawn from a vein. The tubes were sent by mail to the Department of Medical Biochemistry Oslo University Hospital and analyzed within 24 hours. HbA1c EDTA blood was analyzed with a Tosoh G7 HPLC analyser (Tosoh Bioscience, Inc., San Francisco, CA, USA) which uses "high performance liquid chromatography" as the separation principle. The analytical variation is 1.7 %. 3. Cholesterol, LDL and HDL in serum were analyzed by the enzymatic colorimetric method in the Cobas 8000. Analytical variation coefficients are respectively 3.0, 4.0 and 3.5 %. 4. CRP in serum was quantified by the particle enhanced immunoturbidimetric method on Cobas 8000 (Cobas 8000 Modular Analyzer Roche Diagnostics, www.roche.com). Analytical variation is 8.0 %. Blood was collected at the same time of the day on both occasions.	—
