What are the Fast twitch muscles and slow twitch muscles?

Answer 1

Fast twitch muscle fibres are ones used for sudden bursts of physical activity, such as sprinting or weight lifting. Slow twitch muscle fibres meanwhile are designed for extended periods of contraction, such as keeping a person's head supported or maintaining a standing posture.

Physiological differences between the two fibres are largely down to their different energy requirements. Slow twitch fibres have more surrounding capillaries, more mitochondria and a larger amount of myoglobin within the muscle (causing them to be red in color). Meanwhile fast twitch fibres have a store of glycogen to provide a quick burst of energy when the muscles come into action.

Answer 3

there actually called fast twitch fibres and slow twitch fibres ! and fast twitch fibres are in your muscles and they determine if your going to be fast at a certain thing or the slow twitch fibres the same but slowly :)

if you have more fast twitch fibres you will be faster then someone with more slow twitch fibres.

like Usain Bolt he has a lot of fast twitch fibres that's why he is so fast !

Answer 4

Facts about the two types of "fast twitch muscle fibers" include all of these statements:

A more power and strength

B fatigues faster and longer recovery time

C Type IIa endurance but less strength

D Type IIb strength but less endurance

Answer 5

Yes, Slow and fast twitch muscles work together. Fast twitch muscles work much harder at first. Slow twitch muscles keep going when fast twitch muscles tire and slow down.
