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.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
