How Does Caffeine Affect the Rate of Your Pulse?

Overview

Objectives/Goals This experiment was conducted to find the effect of caffeine on the rate of pulse of humans. The pulse rate of five persons of different age levels were measured before and after the consuption of two bervages that contain caffeine. The results showed that pulse rates tend to increase about 20 minutes after compsuntion of both bervages. The experiment alsoshowed that there is no considerable difference in increase in the rate of pulse in response to the two sources of caffeine. Methods/Materials 50 persons 50 16oz cups of coffee 50 16oz cups of Coca- Cola Results I moitored the subjects pulse rate before and after drinking the caffine. I discovered how thier puslse rate increased, especially on the smaller children. Beside the pulse rate increase I noticed other symptoms. some of them were loss of sleep, and an energy boost. Conclusions/Discussion The results supports my hypothesis. All fifty persons pulse rate were increasing after they drank the berverages that contained caffeine.
