Resting and Early Post-Exercise SBP and DBP

Resting and exercising systolic BP —
1. What was the average resting systolic BP?
2. What was the average exercising systolic BP?
3. 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?
Resting and exercising diastolic BP —
1. What was the average resting diastolic BP?
2. What was the average exercising diastolic BP?
3. The range of normal resting diastolic BP for these patients was 75-85 mmHg. Did diastolic BP increase, decrease, or not change with exercise?

2. What was the average exercising CO?
3. The range of resting CO for the subjects in this experiment is 4.55-5.55 L/min. Did CO increase, decrease, or not change with exercise?
Resting and Exercising SVR —
1. What was the average resting SVR?
2. What was the average exercising SVR?
3. The range of resting SVR for the subjects in this experiment is 10.2-12.03 mmHg per min/L. Did SVR increase, decrease, or not change with exercise?

The range of resting SVR for the subjects in this experiment is 10.2-12.03 mmHg per min/L. Did SVR increase, decrease, or not change with exercise? undefined 1. Explain what caused the observed changes in systolic BP and MAP with exercise. undefined 2. Compare the resting and exercising systemic vascular resistance values and discuss what causes the observed change with exercise. undefined 3. Explain how the change in MAP and SVR affected blood flow and why this is important. undefined 4. Restate your predictions that were correct and give data from your experiment that support them. Restate your predictions that were not correct and correct them with supporting data from your experiment. undefined 1. Calcium channel blockers, a type of anti-hypertensive drug, block the entry of calcium into smooth muscle which causes smooth muscle to relax. Explain how this decreases blood pressure. undefined 2.
