LABORATORY REPORT 1 Activity: Effect of Exercise on Arterial Pressure and Vascular Resistance Name: Instructor: Date: 03/2015 Predictions Exercise will cause MAP to decrease 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 Sphygmomanometer 2. Cardiac output Cardiac output 3D imaging 3. Heart rate Heart rate ECG Results Table 2: Effect of Exercise on Systolic and Diastolic Blood Pressure (SBP, SDP), Heart Rate (HR) and Stroke Volume | 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) | 123 | 85 | 74 | 0.079 | 149 | 85 | 145 | 0.106 | 121 | 81 | 73 | 0.076 | 145 | 81 | 146 | 0.109 | 122 | 82 | 73 | 0.077 | 147 | 82 | 147 | 0.107 | 122 | 83 | 73 | 0.077 | 147 | 83 | 146 | 0.107 | 147 | 83 | 146 | 0.107 | | 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) | 123 | 85 | 74 | 0.079 | 149 | 85 | 145 | 0.106 | 121 | 81 | 73 | 0.076 | 145 | 81 | 146 | 0.109 | 122 | 82 | 73 | 0.077 | 147 | 82 | 147 | 0.107 | 122 | 83 | 73 | 0.077 | 147 | 83 | 146 | 0.107 | 147 | 83 | 146 | 0.107 | (SV) Resting and Early Post-Exercise SBP and DBP 1.
