Overview
Brief Summary
The purpose of this research is to gather data on how exercise can help recovery of muscle mass, strength, and physical function after bedrest in older adults with pre-diabetes and type 2 diabetes.
Detailed Description
Older adults with type 2 diabetes (T2D) experience an accelerated rate of sarcopenia, which is the deterioration in muscle mass, strength, and physical performance. Periods of disuse caused by illness or hospitalization causes rapid loss of muscle mass and strength, which negatively impact physical function upon re-ambulation. Without adequate rehabilitation, physical function does not fully recover in older adults following disuse, reducing the quality of life and loss of independence. In this study, participants will enter a 10-day strictly controlled bed rest intervention at the Translational Research Institute (TRI) clinical research unit. Participants are randomized to either a progressive 4-week aerobic and resistance training recovery program at the exercise training or an ambulatory recovery group. The overall objective of this project is to determine how an exercise intervention can aid in recovery of muscle mass, strength and physical function following bed rest in older adults with pre-diabetes and T2D.

Determined by high resolution respirometry in permeabilized muscle fiber bundles
Secondary Outcomes
- Insulin Sensitivity(mmediately following bed rest, and following the exercise or non-exercise recovery phase)
- Physical function(mmediately following bed rest, and following the exercise or non-exercise recovery phase)
