Experimental Design Background information: Caffeine has been shown to raise blood pressure by a release of lipids into the blood and an increase in heart rate and acts as a vasoconstrictor. Caffeine crosses the blood brain barrier and blocks adenosine’s receptor sites. This competitive inhibition increases epinephrine adrenaline and dopamine. An experiment performed by Nurminen, L Niittynen, R Korpela and H Vapaatalo in the Institute of Biomedicine, Department of Pharmacology and Toxicology, University of Helsinki, Finland determined that caffeine raises blood pressure. According to McClaran and Whetter, caffeine has no effect on breathing rate. Haldi, Bachmann, Ensor and Wynn supported this in their study as well. Hypothesis: The participants with a caffeine lifestyle will have a greater blood pressure and a lower breathing rate than the participants without a caffeine lifestyle. The subjects with a caffeine lifestyle will also take longer to reach their resting blood pressure than those without a caffeine lifestyle. Expected results: The subjects with a caffeine life style will show a blood pressure with systolic and diastolic pressures approximately 10 point higher than the subjects without a caffeine lifestyle and will. Materials 5 subjects, two who have a caffeine lifestyle and three who do not A digital sphygmomanometer Methods Ask the five subjects when the last time they consumed caffeine and approximately how much caffeine
