Describe the potential benefits versus adverse effects of caffeine use among athletes.
Many athletes find that caffeine seems to provide a physical boost during endurance sports. Although some research supports this idea, the effectiveness of caffeine seems to depend on the activity. No one has yet shown exactly how caffeine benefits performance. One line of thinking is that caffeine could beneficially alter fuel use to spare glycogen, but this has not been supported by research. Potential benefits of caffeine must be weighed against its known adverse effects: stomach upset, nervousness, irritability, headaches, dehydration, and diarrhea. High doses of caffeine also constrict the arteries and raise blood pressure above normal, making the heart work harder to pump blood to the working muscles, an effect potentially detrimental to sports performance.
