WebOct 4, 2024 · White muscle fibers (fast twitch fibers): These muscle fibers contract very quickly and are responsible for intense, explosive and powerful movements. Red muscle fibers (slow twitch fibers): Muscles that contract slowly but are very persistent are called red muscle fibers. Which type of muscle fiber is used depends on the movement that we ... WebNov 18, 2024 · In contrast, white fibers (fast-twitch fibers) are larger in diameter. Their mitochondria and lipid droplets are smaller and less numerous than those of red fibers [ 2 ]. The properties of red muscle fibers make them very effective in postural maintenance, while white muscle fibers are suited for bursts of intense muscle activity [ 3 ]. WebSep 3, 2024 · The red muscles use oxidative phosphorylation to obtain ATP. Oxidative phosphorylation occurs in the red muscles as the process requires a lot of oxygen, and the red muscles contain high amounts of myoglobin. The process is slower than glycolysis, but much more efficient, which is why slow-twitch muscles do not tire easily. citizen watches bands replacement
