Ultrasound assessment of hamstring muscle size using posterior thigh muscle thickness
Clinical Physiology and Functional Imaging, 2014SummarySeveral studies have investigated the relationship between ultrasound‐measured muscle thickness (MT) and individual muscle cross‐sectional area (CSA) and muscle volume (MV) in extremity and trunk muscles; however, the hamstring muscle has not been studied.

Cardiac muscle fiber size in African cardiomyopathies
American Heart Journal, 1974Abstract The average size of the cardiac muscle fibers in cases of CUO is the same as that in normal cardiac muscle, whereas the fibers in cases of EMF are 40 per cent larger. The widespread impression that cardiac muscle fibers are hypertrophied is probably due to the fact that there is a much greater variation in cell size in CUO than in EMF ...

Abdominal muscle size and symmetry in normal subjects
Muscle & Nerve, 2006AbstractThis study was undertaken to establish normal reference ranges for abdominal muscle size and symmetry and to examine the effects on these of gender and age. We studied 123 subjects, consisting of 55 men (aged 21–72 years) and 68 women (aged 20–64 years). Real‐time ultrasound imaging of the abdominal muscles was performed.

Size and shape of skeletal muscle M-protein
Journal of Molecular Biology, 1982Abstract M-protein was isolated from chicken pectoralis muscle and shown to be relatively homogeneous by the criterion of high-speed equilibrium ultracentrifugation. A sample of the protein was rotary shadowed with platinum and examined by electron microscopy.

Ultrasound Assessment of Adductor Muscle Size Using Muscle Thickness of the Thigh
Journal of Sport Rehabilitation, 2012Context:Previous studies investigated the relationship between ultrasound-derived anatomical muscle thickness (MTH) and individual muscle cross-sectional area (CSA) and muscle volume in several limb and trunk muscles; however, the adductor muscle that contributes to hip adduction and pelvic stabilization, as well as balance ability, has not been ...

MUSCLE BULGING REDUCES MUSCLE FORCE AND LIMITS THE MAXIMAL EFFECTIVE MUSCLE SIZE
Journal of Mechanics in Medicine and Biology, 2006A biomechanical model was generated in order to investigate the possible mechanisms behind reductions in muscle performance due to muscle bulging. It was shown that the proportion of fiber force contributing to the total muscle force is reduced with fiber bulging and that the cause of this reduction is due to the intramuscular pressure (IMP) created ...

Fiber Types and Size in Equine Skeletal Muscle
American Journal of Veterinary Research, 1976SUMMARY Frozen sections of equine musculus semitendinosus were examined for myosin adenosine triphosphatase (ATPase) and reduced nicotinamide adenine dinucleotide-tetrazolium reductase (NADH-TR), using standard histochemical procedures, and the proportions of the various fiber types and average fiber sectional size were determined. With ATPase staining,

Signalling and the control of skeletal muscle size
Experimental Cell Research, 2010Skeletal muscle is highly adaptive to environmental stimuli and can alter its mass accordingly. This tissue is almost unique in that it can increase its size through two distinct mechanisms. It can grow through a cellular process mediated by cell fusion, or it can increase its size simply by increasing its protein content.

Muscle Fiber Size and Chronic Exposure to Hypoxia
1989Sarcomere length is practically never considered when fiber size and dependent variables are compared between muscles or experimental conditions. Because of the direct dependence of fiber cross-sectional area on muscle shortening, it is imperative to normalize measurements of fiber size, and related variables (e.g.
