Purpose This narrative review provides an overview of the current knowledge of B-mode
ultrasound-derived echo intensity (EI) as an indicator of skeletal muscle quality. Method …

Muscle quality (MQ), defined as the amount of strength and/or power per unit of muscle
mass, is a novel index of functional capacity that is increasingly relied upon as a critical …

Skeletal muscle size is an important factor in assessing adaptation to exercise training and
detraining, athletic performance, age-associated atrophy and mobility decline, clinical …

Quantifying echo intensity (EI), a proposed measure of muscle quality, is becoming
increasingly popular. Additionally, much attention has been paid to regional differences in …

Background Ultrasonography is used to evaluate muscle quality (ie echo intensity [EI]), but
an attenuation of ultrasound waves occurs in deeper tissues, potentially affecting these …

The length–tension relationship affects knee extension performance; however, whether
anatomical variations in different quadriceps regions affect this relationship is unknown …

Skeletal muscle is the largest organ system in the human body and plays critical roles in
athletic performance, mobility, and disease pathogenesis. Despite growing recognition of its …

Background This study compares the reproducibility of freehand (FH) vs. foam cast (FC)
scans and investigates the intrarater reliability of the ultrasound FC muscle architecture and …

Evaluating anatomical contributions to performance can increase understanding of muscle
mechanics and guide physical preparation. While the impact of anatomy on muscular …

Objective: Recumbent rest elicits a decrease in muscle size of the lower extremity, but the
extent of decrease may be related to differences in muscle quality. This could have …
