This paper reviews the classification and characteristics of muscle fibers, along with the classical mechanisms of muscle fiber type transitions. Additionally, the role of exercise -induced muscle fiber type tr
Classification of muscle fiber type The acto-myosin ATPase activity has a different sensitivity under the different pH conditions. Based on this principle, Brooke and Kaiser (1970) showed the method with a range of pH preincubations and three main fiber types have been conventionally determined by...
Total fiber number and number of type I v. type II fibers were determined from high resolution images of muscle cross sections. Total plantaris fiber number declined with age (decrease of 34% in 36 mo compared to 24 mo) but fiber number was not significantly different between the 36 mo ...
muscle fiber typeMyHC1slow‐twitch muscletaste sensorThe difference of muscle fiber type composition affects several parameters related to meat quality; however, the relationship between muscle fiber types and meat taste is unclear. To elucidate this relationship, we determined the taste of various ...
Fully understanding insulin resistance in skeletal muscle at the cellular level is challenging because this tissue includes multiple muscle fiber types that vary greatly in their metabolic properties10. The gold standard for muscle fiber type classification is based on myosin heavy chain (MHC) isoform ...

Hundreds of genes, including muscle creatine kinase (MCK), are differentially expressed in fast- and slow-twitch muscle fibers, but the fiber type-specific regulatory mechanisms are not well understood. Modulatory region 1 (MR1) is a 1-kb regulatory regi
Muscle Structure and Classification Skeletal muscle comprises the fibrillar proteins myosin (a thick filament) and actin (a thin filament) that interact to cause muscle contraction, a process requiring energy in the form of adenosine triphosphate (ATP). Different muscle types have been classified accor...
