The biological question under investigation is: Does the sensation of falling backwards cause activation of sympathetic nervous system? We hypothesized that that systolic blood pressure will increase after “trust fall” due to activation of the sympathetic nervous system and diastolic blood pressure will remain the same. This hypothesis is supported by the fact that a free falling sensation activates an individual’s fight or flight response. We substituted a “trust fall” to simulate a free fall, in hopes of triggering a response from the sympathetic nervous system. This question is in particular interest because by activating the sympathetic nervous system the neurotransmitter adrenaline is increased. Many people purposefully induce an adrenaline rush but do not understand the biology behind activating the sympathetic nervous system. Methods For our particular study we had forty-one test subjects. The blood pressure of each subject was taken during resting state and after a trust fall. Our subjects were University of Oregon students between the ages of 18 to 22. We performed studies on both males and females and recorded gender during our data collection. After completing forty-one tests we complied the data into an excel spreadsheet comparing systolic and diastolic blood pressure before and after experiment. We used a paired t-test to compare the control with the experimental of both the systolic and diastolic blood pressures. In addition we found the average and the standard deviation of each data section. The only piece of equipment used was a standard blood pressure cuff. We observed the following study protocol:

Marla Waters BI 212 1. Take the subjects blood pressure, following the protocol outlined in the University of Oregon Biology 212 lab manual (Carrier, 2013). 2. Stand subject up in a space away from objects that they could hit themselves on. 3. Subject should be a little more than arms length away from catcher. 4. Catcher asks subject to confirm distance.

    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.
