BIOS 255 Week 4 Lab: #7 Effect of Exercise on Arterial Pressure and Vascular Resistance LABORATORY REPORT Activity 7: Effect of Exercise on Arterial Pressure and Vascular Resistance Name: Lisa Foley Instructor: Prof. Wiethop Date: January 25th, 2015 PREDICTIONS 1. During exercise: MAP increase 2. During exercise: Vascular resistance increase 3: During exercise: CO increase MATERIALS AND METHODS 1. Dependent Variable: HR, SV, BP 2. Independent Variable: level activity 3. Controlled Variables: age and gender 4. Identify one variable that was not controlled in this study (not dependent or independent variables. Hint: Think about the possible differences between subjects. weight was not something that was controlled in the experiment 5. SVR was calculated using values for BP, CO, and HR. What instrument was used to measure each of the following? 1. Blood pressure: sphygmomanometer 2. Cardiac output: MRI or a stethoscope to hear the blood flow 3. Heart rate: Electrocardiography RESULTS See Table 2: Effect of Exercise on Systolic and Diastolic Blood Pressure (SBP, SDP), Heart Rate (HR), and Stroke Volume (SV) See Graph: Resting and Early Post-Exercise SBP and DBP 1. Resting and exercising systolic BP: a. What was the average resting systolic BP? 123 b. What was the average exercising systolic BP? 148 c. The range of normal resting systolic BP for the subjects in this experiment is 115–125 mmHg. Did systolic BP increase, decrease, or not change with exercise? Increase 2. Resting and exercising diastolic BP: a. What was the average resting diastolic BP? 83 b. What was the average exercising systolic BP? 83 c. The range of normal resting diastolic BP for these patients was 75–85 mmHg. Did diastolic BP increase, decrease, or not change with
