Nutrition and Aerobic Exercise in Chronic Stroke

Completed · Not applicable

Conditions studied: Stroke

In brief

Strokes are very common in the United States and occur more in the elderly. The number of strokes is likely to double in the next 50 years. Many stroke survivors are sedentary and have a poor dietary intake, which results in abnormalities in fuel utilization (eg carbohydrate versus fat). This study will examine the effects of dietary modification and treadmill training on fuel utilization and physical function. We will study skeletal muscle oxidative stress in chronic stroke patients and the ability to employ dietary modification and exercise training to reverse these abnormalities in this ethnically diverse population.
