First seen Feb 01, 2026 · Last updated May 17, 2026 · Updated 15 times

Summary

This study looks at how middle-aged men and women (ages 50-65) recover muscle after one week of not using one leg. Participants will then do a week of rehab exercises. Researchers want to find out if men and women recover differently and what happens inside the muscle at the molecular level. The goal is to create better recovery plans for people who lose muscle from being inactive.
