Role of Microvascular Insulin Resistance and Cardiorespiratory Fitness Diabetes

Description

The goal of this two-site grant proposal is to determine the role of the decreased insulin-mediated muscle perfusion found in type 2 diabetes in contributing to the development of cardiac and skeletal muscle dysfunction and subsequent functional exercise impairment. In addition, it is also our goal to determine whether exercise training attenuates insulin resistance and restores insulin-mediated perfusion to the heart and to skeletal muscle, leading to improved cardiac function and exercise performance.

Conditions

Type 2 Diabetes, Overweight and Obesity
