Explain caffeine’s effect on the body and both the positive and negative impacts it can have on physical performance
What will be an ideal response?
Caffeine is a stimulant that elicits a number of physiological and psychological effects in the body. Caffeine may enhance alertness and reduce the perception of fatigue. Caffeine-containing beverages should be used in moderation, if at all, and in addition to other fluids, not as a substitute for them. Carbonated soft drinks that contain caffeine may make a person feel fuel quickly and limit their fluid intake; this could potentially put an athlete or individual at risk for dehydration when active.
Some research supports the use of caffeine to enhance endurance and, to some extent, to enhance short-term, high-intensity exercise performance. However, the possible adverse effects from caffeine intake includes stomach upset, nervousness, irritability, headaches, and diarrhea must be weighed against any potential benefits. Caffeine is a restricted substance by the National Collegiate Athletic Association, which allows urine concentrations of 15 milligrams per liter or less (equivalent to about 5 cups of coffee consumed within a few hours before testing). Urine tests that detect more caffeine than this disqualify athletes from competition.
