Webb4 feb. 2024 · Furthermore, they are separated into two types: slow-twitch (Type I) muscle fibers and fast-twitch (Type II) muscle fibers. Slow-twitch muscle fibers can generate energy over extended periods. On the other hand, fast-twitch muscle fibers can produce massive amounts of ‘explosive’ energy in a very short period. Webb31 jan. 2024 · Type I: Slow Twitch Fibers The first type of fiber we will look at is the type I, or slow twitch fibers. These fibers are slow to contract (hence, slow twitch), and can sustain muscular contractions for an extended period of time. This factor makes them ideal for endurance type of events where one is exercising for long durations.

Webb9 feb. 2013 · The size principle of motor unit recruitment dictates that motor units are recruited on the basis of their size where small, slow motor units (slow twitch fibres) are recruited first, followed by progressively larger units (eventually fast-twitch fibres) until the required force for the task at hand is met (15,16).
