Beth has trained extensively to get ready for a big swimming event. She has developed her muscle mass to increase her strength so she can surpass those male competitors who have longer arms and legs than she does. To keep those muscles working in top form, she must supply them with enough oxygen to help them produce energy. Why does Beth have an additional physical obstacle to overcome before she can beat her male competitors?

Question

Quizplus · Accepted Answer

The question states that Beth needs to supply her muscles with enough oxygen to produce energy. This is done through the cardiovascular and respiratory systems, which transport oxygen to the muscles. It is likely that Beth's heart and lungs are smaller than her male competitors', meaning they have to work harder to supply the same amount of oxygen to her muscles. This could pose an obstacle to her performance, particularly in an endurance race.
