Name: Michelle Blake
Instructor: Leon Zacharowicz
Date: 1/25/15
PREDICTIONS
1. During exercise: Increase
2. During exercise: Increase
3: During exercise: Decrease
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 the possible differences between subjects.
Height and weight
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
3. Heart rate: ECG
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? 122mmHg
b. What was the average exercising systolic BP? 147mmHg
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? 82 b. What was the average exercising systolic BP? 84
c. The range of normal resting diastolic BP for these patients was 75–85 mmHg. Did diastolic BP increase, decrease, or not change with exercise? No change
See Table 3: Resting and Early Post-Exercising on Mean Arterial Blood Pressure (MAP), Cardiac Output (CO), and Systemic Vascular Resistance (SVR)
See Graph: Resting and Exercising MAP, CO, and SVR
3. Resting and Exercising MAP:
a. What was the average resting MAP? 95.3mmHg
