Creatine Monohydrate Use and Muscle Stretching in Peripheral Artery Disease

Detailed Summary

To utilize near-infrared spectroscopy to investigate if the research device, which induces muscle stretching, and creatine loading impact submaximal exercise performance in aged and PAD patients. Near-infrared spectroscopy (NIRS)-derived tissue oxygenation responses will be obtained during device placement (muscle stretch) and during a walking test (i.e., six-minute walk test). Muscle oxygenation at rest and during device placement will be assessed with Magnetic Resonance Imaging. It is hypothesized that the stretching protocol will improve both NIRS-derived tissue oxygenation and magnetic resonance-derived muscle oxygenation and that creatine supplementation will further improve phosphorus metabolite muscle performance. All patients will undergo either 4 weeks of stretch training with- or- without creatine supplementation according to previously defined creatine guidelines.
