Exploring the Connection Between Muscle and Bone in Healthy Women

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates how muscle tissue influences bone density through the secretion of myokines in healthy women aged 20 to 89. It aims to recruit 425 participants from three centers in France and will utilize DXA scans to measure bone mineral density at various sites. The study will also collect blood and saliva samples and conduct physical tests to assess muscle strength. The goal is to develop updated reference curves for bone density and body composition, enhancing our understanding of the relationship between muscle and bone health.
