Correct Answer:
B:) High involvement
Explanation:
Type I muscle fibers are “slow-twitch” and have higher resistance to fatigue due to higher capacity for aerobic energy supply. Type II muscle fibers are “fast-twitch” and have higher capacity for rapid force generation, and lower resistance to fatigue due to greater anaerobic energy supply. As the 100 meter sprint is a high-intensity, short-duration activity, there will be higher relative involvement of Type II muscle fibers which use anaerobic energy systems.
