Effect of Exercise on Arterial Pressure and Vascular Resistance Abbie DeBerg Ms. Brantley May 30, 2012

Predictions
1. During exercise increase. 2. During exercise decrease. 3. During exercise increase.

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

4. Identify one variable that was not controlled in this study (not dependent or independent variables; hint: think aboutpossible differences between subjects). 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 3D imaging 3. Heart rate ECG

Results Table 2: Effect of Exercise on Systolic and Diastolic Blood Pressure (SBP, SDP), Heart Rate (HR) and Stroke Volume (SV) Systolic BP (mmHg) 121 123 123 122 Resting Values Diastolic BP HR (beats/min) (mmHg) 81 72 84 73 83 73 83 73 SV (mL) 0.075 0.079 0.077 0.077 Systolic BP (mmHg) 150 147 146 148 Immediately After exercise Diastolic BP HR (beats/min) (mmHg) 82 145 85 146 84 147 84 146 SV (mL) 0.107 0.105 0.106 0.106

Subject 1 Subject 2 Subject 3 Averages

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? increase

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