WebCharacteristics of slow twitch (red) fibers include: high myoglobin content, high mitochondrial density, resistance to fatigue, and primarily aerobic metabolism. Characteristics of fast twitch (white) fibers include: low myoglobin content, low mitochondrial density, rapid contraction speed, and primarily anaerobic metabolism. WebFast-twitch fibers have fewer mitochondria, capillaries, and myoglobin than slow-twitch fibers. Such fibers are used for movements requiring rapid burst-like movement, such as …
WebDec 2, 2024 · Slow-twitch fibers are used to maintain posture. They are usually found in red muscles, indicative of the large concentration of myoglobin providing a steady supply of oxygen to them. The red muscles use oxidative phosphorylation to obtain ATP. http://pressbooks-dev.oer.hawaii.edu/anatomyandphysiology/chapter/exercise-and-muscle-performance/
