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
