The Effects of Short-time High-intensity Interval Training on Tissue Glucose and Fat Metabolism in Healthy Subjects and Patients With Type 2 Diabetes

Not Applicable

• Conditions: Type 2 Diabetes Mellitus; Healthy Volunteers
• Interventions: Behavioral: HIT exercise intervention; Behavioral: Aerobic exercise intervention

• Registration Number: NCT01344928
• Lead Sponsor: Turku University Hospital

Brief Summary

The objectives of this study are to investigate the effects of short-time high-intensity interval training on tissue glucose and fat metabolism in healthy lean subjects and type 2 diabetic patients using modern and noninvasive imaging methods positron emission tomography (PET), magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS).

5. History of rest or exercise-induced asthma
6. Previous use of anabolic steroids, additives or any other substrates
7. Smoking of tobacco, taking of snuffs, or use of narcotics.
8. Significant use of alcohol
9. Any other condition that in the opinion of the investigator could create a hazard to the subject safety, endanger the study procedures or interfere with the interpretation of study results
