An athlete trains for a weight-lifting event in the olympics. what type of muscle fiber would be the most important for this athlete to develop?
select one:
a. slow twitch, because they contain more mitochondria than fast twitch fibers
b. fast twitch, because they primarily use aerobic respiration
c. fast twitch, because they primarily use lactic acid fermentation
d. slow twitch, because they can contract for long periods of time without fatiguing

The correct answer will be option c.

Explanation:

Two types of skeletal muscles are used in exercise: fast twitch and slow twitch.

Slow-twitch muscles help in long-endurance exercises like marathon running as they have more mitochondria and use aerobic respiration to produce energy.

But fast-twitch especially types IIb muscle is used in the exercise which requires powerful bursts like weight-lifting and sprinting as fibres do not have the capability to store oxygen so begin producing energy by lactic acid fermentation.

Thus, option c is the correct answer.
