The oxygen-binding. function of myoglobin, in situ in the bundles of muscle. fibers, was abolished by chemical treatment, and the contribu-. tion of myoglobin toward the oxygen uptake of the muscle fiber. bundles was estimated from the difference in the steady state.
Type I muscle fiber is also known as slow twitch oxidative fibers. Muscle fiber types can be broken down into two main types: slow twitch (Type I) muscle fibers and fast twitch (Type II) muscle fibers.Type I fibers are used in lower-intensity exercises such as very light resistance work aimed at muscular endurance and long-duration aerobic activities such as 5K and 10K runs.ain article: Type II Muscle Fiber. Type II muscle fiber is also known as fast twitch muscle fibers. These fast twitch fibers can be further categorized into Type IIa and Type IIx fibers, which are also known as fast twitch oxidative and fast twitch glycolytic, respectively.
