It is averaged that 200ml (two cups of coffee) is the average intake of caffeine in America per person. However Athletes strive for ways to perform and enhance there performance through any way possible, this includes through the uses of caffeine because it acts as a stimulant against the central nervous system causing heart rate to increase which may allow the consumer to feel extra amounts of energy. This perhaps would allow athletes to increase there performance because of more blood with oxygen being transported around the body. However after performance and exercise, athletes take a considerate amount of time to recover from exercise and allow the body to get back to resting heart rate, Caffeine may still be in effect however after exercise causing the heart to still produce a higher heart rate. In order to better understand the effects of caffeine on exercise and performance, this essay will research the effect of caffeine on recovery rates during aerobic exercise.
