|Condition or disease||Intervention/treatment||Phase|
|Physical Inactivity||Other: Reduced Physical Activity||Not Applicable|
Pre-testing- The baseline evaluation will assess muscle function and strength, and an oral glucose tolerance test. After the baseline visit, participants will be provided with a step activity monitor to track their level of activity. This will provide a baseline of the participant's normal level of physical activity so an accurate level of 75% activity reduction can be determined. A 3-day daily dietary diary will be provided for the participant to self-report prior to the experiment, as well.
Day 1- After the participant completes their normal activity log and dietary diary, they will be asked to return to the research center for a body composition scan and a metabolic study.
The metabolic study will involve blood sampling from an arm vein and muscle biopsies from the thigh before and after a leucine drink.
2-week period of inactivity- After the metabolic study, the participant will return home and maintain a reduced level of activity (75% reduction) for a two-week period. During this time, the participant will receive phone calls from research personnel in order to maintain adherence to the intervention.
Day 14- After the 2-week reduced activity period, the participant will return to the research center to receive a body composition scan and undergo a metabolic study identical to 'Day 1'.
Post-testing- After Day 14, the participant will be asked to return once again to the research center for a oral glucose tolerance test and the exercise lab for muscle function testing.

Experimental: Reduced Physical Activity
Participants will reduce their physical activity levels for 2-weeks by approximately 75% of their baseline level of physical activity
Other: Reduced Physical Activity
Participants will reduce their level of physical activity for 2-weeks as defined as approximately 75% reduction from their baseline level of physical activity.
