Ultrasound-derived echo intensity (EI) effectively measures muscle quality in children aged 10-14 years, with high reliability indicated by ICC values.
The study plans to enroll 200 children, assessing muscle function through maximal voluntary contraction and a 30 s sit-to-stand test.
Construct validity of EI will be established by analyzing relationships between EI and functional muscle quality, controlling for body composition and physical activity.
Results will provide insights into muscle quality disparities among children, particularly focusing on those with obesity or low physical activity levels.
