Slow vs fast twitch fibers
Webb15 nov. 2024 · The difference between fast and slow muscle fibers is slow twitch muscle fibers contract slowly but have good endurance and energy production efficiency. On the other hand, fast twitch muscle fibers contract quickly and rapidly producing more force, but they tire out more quickly and are not as efficient in terms of energy. Webb12 jan. 2024 · Skeletal muscle contains tiny fibers that can be categorised as either fast or slow twitch. Simply put, fast twitch fibers create explosive energy but get tired quickly, …
