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 …

This study had two aims. Aim1 was to determine the agreement between midthigh vastus
lateralis (VL) cross-sectional area measured by ultrasound (mCSAUS) versus magnetic …

Echo intensity (EI) is being increasingly utilized by investigators as an index of skeletal
muscle quality. Previous studies have reported independent associations between EI versus …

The purpose of this study was to compare the independent and combined effects of high‐
intensity interval training (HIIT) and essential amino acids (EAA) on lean mass, muscle …

Purpose Many modern-day children are at risk of pediatric dynapenia (muscle weakness).
We examined the effects of a 12-week resistance training (RT) program on neuromuscular …

Background Fast gait speed is being increasingly recognized as an important clinical tool in
older adults. However, the underlying muscular and functional contributors to fast gait speed …

Background Disuse of a muscle group, which occurs during bedrest, spaceflight, and limb
immobilization, results in atrophy. It is unclear, however, if the magnitude of decline 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 …

Diferentes investigaciones se han enfocado en mejorar el índice de calidad muscular (MQI)
para aumentar la función muscular en población adulta. Sin embargo, en la población …

Muscle quality is typically defined as muscle strength relative to muscle size. Echo intensity
has gained popularity as an index of skeletal muscle quality. There is common agreement …
