LABORATORY REPORT
Activity: Name: Instructor: Date: Effect of Exercise on Arterial Pressure and Vascular Resistance Professor 09.30.2014

Predictions
Exercise will cause MAP to increase Exercise will cause systemic vascular resistance to decrease Exercise will cause CO to increase

Materials and Methods
1. Dependent Variable HR, SV, BP 2. Independent Variable level of activity 3. Controlled Variables gender, age

4. Identify one variable that was not controlled in this study (not dependent or independent variables; hint: think about possible differences between subjects). Race 5. SVR was calculated using values for BP, CO, and HR. What instrument was used to measure each of the following? 1. Blood pressure sphyhgmomanometer 2. Cardiac output 3D imaging 3. Heart rate ECG

Resting and Early Post-Exercise SBP and DBP

1. Resting and exercising systolic BP a. What was the average resting systolic BP? 122 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? increased

2. Resting and exercising diastolic BP a. What was the average resting diastolic BP? 83 b. What was the average
