Question
Slow twitch fibers have
Answer: Option B
:
B
Red fibers are smaller in diameter; white fibers are larger in diameter. Red fibers have more mitochondria than white fibers. Red fibers make up slow-twitch muscle; white fibers make up fast-twitch muscle. Red fibers are more resistant to fatigue than are white fibers. Red fibers have more myoglobin (oxygen binding pigment) and also a large concentration of mitochondriathan white fibers. White fibers store glycogen and use anaerobic metabolism.
Red fiber and slow twitch muscle is for endurance.
White fiber and fast twitch muscle is for a burst of power.
