WebNot surprisingly, slow-twitch fibers, with their high myoglobin content, are more resistant to fatigue; thus a muscle with a high percentage of slow-twitch fibers is well suited for endurance exercise. However, slow-twitch fibers tend to be smaller and produce less overall force than fast-twitch fibers. WebSlow-twitch muscle fibers contain more mitochondria, the organelles that produce aerobic energy. They are also smaller, have better blood supply, contract more slowly, and are more fatigue resistant than their fast-twitch brothers. Slow-twitch muscle fibers produce energy, primarily, through aerobic metabolism of fats and carbohydrates. lehna singh science lehne general anesthetics quizlet
