WebFast-twitch muscle consists of type IIx and IIb fibers, which are characterized by a fast contraction speed, relatively high glycolysis rate and few mitochondria . These disparities may influence the response of muscles to certain physiological and pathological challenges, such as exercise ( 6 ), aging ( 7 ) and insulin resistance ( 8 ). WebSep 26, 2024 · Slow oxidative fibers have structural elements that maximize their ability to generate ATP through aerobic metabolism. These fibers contain many more mitochondria than the glycolytic fibers, as aerobic metabolism, which uses oxygen (O 2) in the …
