An Individual's Ability to Excel in Certain Types of Sports

question 105

Multiple Choice

An individual's ability to excel in certain types of sports may be due to different muscle fiber types. Certain muscle types allow some people, like marathoners, to achieve sustained muscle activity, while other muscle types allow people, like sprinters, to make use of a rapid burst of muscle activity, although the muscles fatigue quickly. The sustained activity of muscles in marathon runners is due to the higher yield of ATP per glucose. What differences would you predict for marathoners' muscles compared to sprinters'?

• A)Marathoners' muscles use a different set of enzymes for cellular respiration.
• B)Marathoners' muscles rely more on oxidative phosphorylation.
• C)Marathoners' muscles require greater oxygen delivery to the muscle cells.
• D)Marathoners' muscles have a greater number of mitochondria.
• E)None of the other answer options is correct.
