A recent newspaper article described a new bottled water that is “super charged” with oxygen. Since the body’s demand for oxygen increases as physical exertion increases, a university athletic coach thought that giving her athletes this oxygenated water would result in better performances. To test this idea, the coach divided her runners up into two groups. During practice, one group was given the super charged, oxygenated water to drink. The other group was given regular water. Both groups completed the same workout and drank the same amount of water (either oxygenated or unoxygenated). At the end of practice, she had all the athletes run 400 meters as fast as they could. She compared the times of the runners who had consumed regular water to those who had consumed the oxygenated water during practice. The coach found that the average time of the oxygenated water drinkers was significantly faster than that of the runners who had consumed regular water during practice. Which of…

When a person is in a state of heat exhaustion, trying to reduce body temperature is a priority over trying to maintain MAP. With this in mind, explain why people in a state of heat exhaustion have a rapid heart rate, but low stroke volume.
