Description
The purpose of this research study is to find out if exercise improves how well the mitochondria work. We also want to know if exercise improves ability to perform physical tasks. Finally, we will also test several components in the blood which may be related to physical abilities. We are doing this research because exercise may improve the overall balance of these components. What we learn in this study may help us to better understand the mitochondria and muscle in people with kidney disease. We hope to use this knowledge to improve their ability to be active and independent.
This study requires

The study doctor or study coordinator will see you for study visits at the UC Davis Medical Center – either the Ambulatory Care Center (ACC) and/or the Imaging Research Center (IRC) depending on the visit. Each participant will undergo a Screening/Enrollment, two ACC (pre- and post-intervention), and two ACC/IRC (pre- and post-intervention) visits. See the study schedule on the last page of this form for an overview.

There will be 2 study groups. We will assign some subjects to just keep getting their usual care. We will assign the other subjects to a 12-week program of exercise. At the end of the study, we will compare muscle metabolism and muscle function in subjects who were and were not assigned to the exercise program. The treatment you get will be chosen by chance, like flipping a coin. Neither you nor the study doctor will choose what treatment you get. You will have a one in four chance of being given each treatment.

Who can participate
