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 of the subjects was not included. 5. SVR was calculated using values for BP, CO, and HR. What instrument was used to measure each of the following? 1. Blood pressure Blood pressure Sphygmomanometer or Blood pressure Cuff 2. Cardiac output Cardiac output 3D imaging 3. Heart rate ECG of the heart rate Results Table 2: Effect of Exercise on Systolic and Diastolic Blood Pressure (SBP, SDP), Heart Rate (HR) and Stroke Volume (SV) Resting Values Immediately After exercise Systolic BP (mmHg) Diastolic BP (mmHg) HR (beats/min) SV (mL) Systolic BP (mmHg) Diastolic BP (mmHg) HR (beats/min) SV (mL) 120 83 74 0.08 146 81 147 0.106 121 81 74 0.075 149 84 146 0.108 125 83 73 0.075 146 81 146 0.109 122 82 74 0.077 147 82 146 0.108 147 82 146 0.108 Laboratory Report/ Nicole Shook/ Effect of Exercise on Arterial Pressure and Vascular Resistance/ Lisa Nelson/ 11.15.2014/ Page [1] of [4]Resting and Early Post-Exercise SBP and DBP 1. Resting and exercising systolic BP - a. What was the average resting systolic BP? 122 mmHg b. What was the average exercising systolic BP? 147 mmHg 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 mmHg b. What was the average exercising systolic BP? 82 mmHg c.
