Trial of Aerobic Exercise Training in Stroke Survivors

Completed · Not applicable

Conditions studied: Stroke, Insulin Resistance, Sedentary Lifestyle

In brief

The purpose of this study is to examine the effects of treadmill training on inflammation in the skeletal muscle and adipose tissue, insulin action in the skeletal muscle, and whole body glucose metabolism in stroke survivors. The fundamental hypothesis of this study is that key inflammatory markers in adipose tissue and skeletal muscle are abnormal, skeletal muscle insulin signaling is impaired, and systemic insulin sensitivity is reduced in hemiparetic stroke patients and that these factors are modifiable and improved by exercise training in stroke patients.
