LAB: Exercise Physiology & Vital Signs Objective: The purpose of this lab to it to gather a better understanding between physical activity and our body s response. It will also help you learn how to measure vital signs including pulse rate, breathing rate, and blood pressure. (Indiana State Academic Standards: Biology, 1.14, 1.15, 1.16, 1.17, 1.18, & 1.19) Background: Breathing rate and pulse rate are maintained by the brain. When a body s needs change, the brain can respond by varying the rate at which breathing and circulation take place. Blood pressure, which is determined by how hard the heart is pumping can also be raised and lowered based on outside stimuli. Pulse rate, breathing rate, and blood pressure are all considered vital signs and are used by medical professionals to determine if a patient s body is functioning properly. Pulse rate is measured in beats per minute and can be calculated by counting the number of heart beats in 15 seconds and multiplying by four. You can find the radial pulse by placing a finger just superior to the wrist in the groove on the thumb side. You can find the carotid pulse on the anterior side of the neck just inferior of the ear. Breathing rate is measured in breaths per minute and can be calculated the same way. Blood pressure is measured in millimeters of mercury (mm Hg) and has 2 different measurements. The first measurement is systolic pressure and is a measure of the pressure in the arteries during ventricular contraction. The second measurement is diastolic pressure and is a measure of the pressure in the arteries when the ventricles are not contracted. There are tools that can be used to gather data on pulse rate and blood pressure. A stethoscope is used to monitor heart sounds and a sphygmomanometer, or blood pressure cuff, can be used to measure blood pressure. Materials: - 1 stethoscope - 1 sphygmomanometer Procedures: (a) (b) (c) (d) (e) (f) (g) (h) (i) (j) Choose 1 team member to be subject 1 of the experiment. If at any time the subject feels uncomfortable or unable to finish the lab, have another team member take his/her place and start over. Have the subject lay on the lab table for two minutes then immediately take their pulse rate, breathing rate, and blood pressure. Have the subject sit in a chair at the edge of a table for two minutes then immediately take their pulse rate, breathing rate, and blood pressure. This is your baseline measurement. Have the subject stand for two minutes then immediately take their pulse rate, breathing rate, and blood pressure. Have the subject do sit-ups for two full minutes then immediately take their pulse rate, breathing rate, and blood pressure. Allow the subject to rest for 3-5 minutes or until breathing rate returns to baseline. Have the subject run in place for two minutes then immediately take their pulse rate, breathing rate, and blood pressure. Allow the subject to rest for 3-5 minutes or until breathing rate returns to baseline. Have the subject do jumping jacks for two minutes then immediately take their pulse rate, breathing rate, and blood pressure. Choose a lab team member to be subject 2 and repeat steps (b) through (i). (NOTE: For better results, pick a team member who is physically different that the other, ie. male and female, short and tall, smaller and bigger. 14
