Summary

This study looks at how menopause and hormone replacement therapy (HRT) change the way the brain talks to muscles. Twenty women who are about to start HRT will be tested before starting, after two months, and after five months of treatment. They also get a voluntary 12-week exercise program. The goal is to understand, not to treat or cure anything.
