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 them produce energy. why does beth have an additional physical obstacle to overcome before she can beat her male competitors?

In swimming competition, the height and the length of limbs of the competitors matter because they determine how quickly they can move through the water and the number of turns they will need to do before reaching the finishing line. Men are naturally at advantage because they are usually taller and have longer legs and arms which help them to be quicker inside the water. This is a classic examples of gender difference in sport.  Beth needs to put in additional works toward the competition in order to be able to finish early more than her competitors despite the fact that she has shorter arms and legs. Continuous training will help her to develop her muscle mass and help her to exert the necessary energy she needs get to the finish line on time.
