Type 1 and 2a fibers were marked with antibodies, and lysosome-associated membrane protein-1 (Lamp1) was used as the lysosomal membrane marker. Quantitative measurements showed a 2.5-3-fold increase of fiber cross-sectional area of both fiber types during therapy and normalization of the Lamp1 ...
We describe a simplified technique for the histochemical determination of three fiber types from a single section of skeletal muscle. Preincubation in a solution of formaldehyde, glycine, and calcium followed by routine myofibrillar adenosine triphosphatase (ATPase) incubation clearly differentiates type I,...
Using quantitative histochemical techniques, it was determined that the tensor tympani muscle of the cat consists of three muscle fiber types: type 1, type 2A (staining characteristics similar to the type 1 and type 2A muscle fibers found in the control tibialis anterior muscles), and a third ...

Muscle Fiber Types The categorization of distinct groups of muscle fibers that can be delineated on the basis on differences in histochemical, biochemical, morphological, and physiological properties. There are three basic muscle fiber types, Type I, or slow twitch fibers which are aerobic and are ...
Muscle fiber types（肌纤维类型）Fiber type differentiation（肌纤维分类） 在肌肉内和肌肉与肌肉之间肌纤维的形态学、生理学和生化特性有很大的区别，这些差异在纤维类型分类基础上形成的，近年来个体纤维内蛋白质表达模式的正确解释是允许纤维类型分类的细化。比如，肌原纤维蛋白质被一种基因以同种型编码存在，...
Entheses are the areas of the bone where muscles, tendons, or ligaments attach1,2. They represent the only direct evidence of the musculotendinous system on skeletal remains2 and are thought to broadly reflect muscular activity. As such, entheses have been used in attempts to reconstruct past...
Some investigators have used differences in the drop in pH during exercise to characterize muscle fiber types (Park et al., 1987). During high-intensity exercise, fast twitch glycolytic muscle fibers become acidotic after 30 s and reach pH values of 6.3 after 1 min. Slow twitch oxidative ...
In most cases, the muscular disease affects the properties of the muscle fibers and as a result, changes their relaxation times. For example, in muscle fibrosis, the damaged striated skeletal muscle is replaced mainly by excessive collagen1,2. The change of muscle fiber type affects the muscle...
Muscle samples were obtained from the middle gluteal muscle before and immediately after the exercises. Four muscle fiber types (type I, IIA, IIA/X, and IIX) were immunohistochemically identified, and the optical density of Schiff staining (OD-PAS) in each fiber type and content of the ...
