WebIn contrast to red muscle fibers, white muscle fibers have less myoglobin and mitochondria and have poor blood flow. Conversely, they have higher glycogen content and glycolysis enzymes. They are also very efficient for a strong and fast contraction of short-term anaerobic metabolism-fuelled contraction. Webfibers. 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. 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.

WebMay 11, 1999 · For the red and white fibers, the force increase was slightly greater in the rigor than in the active fiber. In the case of the swimbladder, a 2-fold larger stretch was applied in the active fiber, but the force change was still just a small fraction of that in rigor. All experiments were conducted at 15°C.
