Many factors, such as breed, nutrition, age, hormone, and exercise, can affect muscle fiber
diameter, type and its composition.
org/content/early/2017/06/20/1619071114) Proceedings of the National Academy of Sciences explains chimpanzees have more of the muscle fibers
known as fast-twitch while humans have more slow-twitch fibers.
Muscle atrophy leads to the geometric distortion of the cell membrane and decreases the diameter of the muscle fiber
, eventually resulting in a reduced muscle cross-sectional area.
To grow a muscle fiber
, the team used muscle precursor cells obtained from mice, which they then differentiated into muscle cells.
number is affected by prenatal conditions such as maternal nutrition, with undernourished fetuses having significantly fewer secondary muscle fibers
(Ward and Stickland, 1991; Dwyer et al.
The expression of skeletal muscle fiber
type-specific proteins and changes in the composition of muscle fiber
depend on developmental factors, neuromuscular activity, muscle load, hormonal levels and aging (Pette and Staron, 1997).
Washington, April 3 ( ANI ): Researchers have revealed that in addition to keeping muscles fit, endurance sport also improves the neuronal connections to the muscle fibers
based on a muscle-induced feedback.
A Leica TCS SP5 (Leica Microsystems, Wetzlar, Germany) confocal laser scanning microscope was used to visualize the muscle fiber
structure of the samples.
To reduce muscle fiber
movement, which can alter the morphology of [Ca.
It is widely accepted that muscle fiber
composition is an important source of variation in meat quality (Wojtysiak et al.
The changes seen in this muscle closely resemble those seen in an acute necrotizing myopathy, except for the distribution of the acute muscle fiber
We have identified the localization of GLUT4 in the skeletal muscle fiber
of STZ-induced diabetic rats using the immunofluorescence staining, and we have also observed that there are distinct differences in thickness of staining owing to treatments of STZ-induced diabetes and/or exercise training.
