Compared to slow twitch oxidative muscle fast twitch glycoly

Compared to slow twitch (oxidative) muscle, fast twitch (glycolytic) muscle:

(a) Fast twitch muscle generates more force and fatigues more quickly.

(b) Fast twitch muscle generates more force and is more fatigue resistant.

(c) Fast twitch muscle generates less force and fatigues more quickly.

(d) Fast twitch muscle generates less force and is more fatigue resistant

(e) Fast twitch and slow twitch muscle are similar in their force generation and fatigue resistance.

Solution

a) Fast twitch muscle generates more force and fatigues more quickly.

This is because they deplete the energy at a fater rate. The fast twich muscles are primarily dependent on anerobic respiration and rely on ATP and glycogen as the energy source and form lactic acid as a by product . the number of ATP molecules that are produced are less and hence they fatigue more quickly.
