Training Effects on Fuel Metabolism

Sponsor: University of Minnesota

Summary

The investigators are interested in how skeletal muscle processes fat and how this may affect insulin resistance. This is an important question since insulin resistance predates and predicts type 2 diabetes. The investigators are especially interested in learning about the effects of weight and training on insulin resistance. The investigators will study people before and after supervised aerobic or yoga training to identify differences in resting fat and sugar metabolism which may lead to differences in insulin resistance. The investigators will test these differences using stable isotopes, and the use of these stable isotopes is experimental. Overweight/Obese Group: Eight visits will be required at the University of Minnesota Clinical Research Unit. Four visits will be done before training (screen and 3 pre-training visits), 1 visit during the training, and 3 post-training visits will be done. In between, the training will take about 16 weeks and will be a supervised treadmill program. Lean/Trained Group: Four visits will be required at the University of Minnesota Clinical Research Unit (screen and 3 study visits).
