Muscle Quality and Subcutaneous Adipose Tissue in the Rectus Femoris and Rectus Abdominis Muscles: Ultrasound Evaluation and Functional Correlation in Older Adults

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.
