Question

what is the difference between slow - twitch and fast - twitch muscle fibers? slow twitch fibers are less resistant to fatigue than fast - twitch fibers. slow twitch fibers are used for short bursts of power, while fast - twitch fibers are used for endurance exercise. slow - twitch fibers are highly resistant to fatigue, while fast - twitch fibers fatigue quickly. fast twitch fibers are highly resistant to fatigue, while slow - twitch fibers fatigue quickly. fast twitch fibers are used for explosive movements, while slow twitch fibers are used for sustained activity.

Explanation:

Slow - twitch muscle fibers are designed for endurance and are highly resistant to fatigue as they rely on aerobic respiration. Fast - twitch muscle fibers generate quick, powerful contractions but fatigue rapidly as they mainly use anaerobic respiration. They are used for explosive movements like sprinting, while slow - twitch fibers are used for activities like long - distance running.

Answer:

C. Slow - twitch fibers are highly resistant to fatigue, while fast - twitch fibers fatigue quickly; E. Fast twitch fibers are used for explosive movements, while slow twitch fibers are used for sustained activity.
