What are the differences between red, white, and intermediate muscle fibres.
Red (type I): good for posturing, LOTS of myoglobin, many mitochondria, mostly oxidative phosphor., slow twitch
White (Type IIa, intermediate): 400m race, oxidative and anaerobic, the most mitochondria, fast twitch, intermediate
White (Type IIb): 10s sprint, anaerobic, low myoglobin, lots of glycogen, easily fatigable, fast twitch
