How Moving Quickly Effects Your Blood Pressure Written on November 27, 2011 Abstract Moving quickly tends to affect your blood pressure. The group proposed to test if standing up quickly from a laying position will decrease your blood pressure. The group tested the subjects blood pressure while they were lying down then we tested it again after they jumped up. Subject 1 had a decrease in their blood pressure from when they were laying down to when they stood up. Subject 2 had a decrease in blood pressure as well. The results show that your blood pressure will decrease when you stand up quickly from a lying down position. Background Blood pressure (BP) is the pressure exerted by circulating blood upon the walls of blood vessels. During each heartbeat, BP varies between a maximum (systolic) and a minimum (diastolic) pressure. The mean BP, due to pumping by the heart and resistance to flow in blood vessels, decreases as the circulating blood moves away from the heart through arteries. Blood pressure drops most rapidly along the small arteries and arterioles, and continues to decrease as the blood moves through the capillaries and back to the heart through veins. When you go from laying down to standing up in one quick motion gravity takes effect and pulls your blood down which decreases the blood pressure. It may also give you lightheadedness and you may possibly faint. In this experiment the subjects’ blood pressure was taken in their resting position (lying down). The goal of this experiment was to see if standing up from a lying position expeditiously would decrease your blood pressure. The subjects’ blood pressure was taken before the experiment, after they were lying down for 2 minutes and after they jumped up. The comparison between the subjects blood pressure while lying down and after they jumped up should determine whether or not moving quickly
