Answer:
The correct answer is - per gram, the marathon runner's muscles would contain more myoglobin than the sprinter's muscles.
Explanation:
Marathon runners have smaller leg muscles and thinner quads and calves as marathon runners require slow-twitch muscles while in sprinters the fast-twitch muscle requires. Slow-twitch muscles of marathon runners have more amount of myoglobin, per gram than fast-twitch muscles.
Myoglobin acts as local oxygen storage that provides oxygen to the muscles in case of less oxygen supply than required temporarily and a marathon race is an intense exercise or activity that requires more oxygen.
