Summary
This study looked at how reducing daily steps by about 70% affects blood vessel function and muscle health in older adults. Researchers measured blood flow in arm and leg arteries to understand the role of oxidative stress. The goal is to learn why inactivity leads to muscle loss and poor recovery, especially after surgery or hospitalization.
