Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this observational, cross-sectional study is to examine the relationship between body composition and muscle quality in women over the afe of 65. The main question it aims to answer is:

How are ultrasound-based measurements of muscle and fat tissue related to functional performance in older women?

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this observational and cross-sectional study, researchers will use ultrasound imaging and physical performance tests to evaluate muscle thickness, subcutaneous fat thickness, abdominal circumference, handgrip strength, and functional performance. These measurements will help identify muscle and fat distribution profiles associated with higher functional risk in older adults.

This study aims to contribute to the understanding of sarcopenic obesity and muscle quality in aging, with the ultimate goal of improving preventive physiotherapy strategies and promoting healthy aging.
