Brief Summary:

High intensity interval training is applied for several diseases.

Hypothesis: High intensity interval training improves insulin sensitivity in patients with type 2 diabetes.

Condition or disease Intervention/treatment Phase
Type 2 Diabetes Other: High intensity interval training Not Applicable

Detailed Description:
Type 2 diabetes mellitus is a multifactorial metabolic disease that is characterized by reduced insulin sensitivity and insulin production leading to impaired glucose tolerance. Overweight and low physical activity are the main risk factors for the development of type 2 diabetes. Increased physical activity has shown to improve insulin sensitivity, hence, exercise plays a significant role in the prevention and therapy of type 2 diabetes. This study aims at investigating the acute and chronic effects of high-intensity low-volume training, that consists of brief bursts of very vigorous exercise separated by recovery periods, on metabolic function in patients with type 2 diabetes, people at high risk for the disease and healthy, lean individuals. Study participants take part in 30 min training session three times a week for a period of 12 weeks. Participants are studied on four occasions, prior to the intervention, after an acute bout of exercise as well as after 6 and 12 weeks of training in order to assess physical fitness, body composition, insulin sensitivity, energy metabolism in muscle, adipose tissue inflammation and neurological function. It is hypothesized that this type of exercise leads to significant improvements in insulin action and oxidative phosphorylation in muscle

Arm Intervention/treatment
Experimental: high intensity interval training Other: High intensity interval training

The intervention consists of 30 minute sessions of high-intensity interval training on a bicycle ergometer three times per week.

Training program: After 5 minutes of warm-up the subject cycles for 10 intervals of 60 s. at 90 % maximum effort separated 60 s at 20% maximum effort, based on a previously performed spiroergometry, followed by 5 minutes of cool-down.

Primary Outcome Measures :
  1. Improvement of Insulin sensitivity by high intensity interval training [ Time Frame: 2 years ]
    High intensity interval training leads to significant improvements in insulin action and oxidative phosphorylation in skeletal muscle.
