Effect of Exercise on Pulse Rate and Blood Pressure
Purpose: To determine the effect of jogging on pulse rate and blood pressure. Hypothesis: If you jog then your heart rate and blood pressure will increase. Materials:
Tape Measure
Blood Pressure Cuff
Procedure:
1. Record resting blood pressure and heart rate.
2. Measure out 100m.
3. Jog 100m (same speed every time)
4. When finished jogging 100m record heart rate and blood pressure. 5. Repeat steps 3&4, 3 more times
6. Calculate average heart rate and blood pressure for the 4 jogs. Observations: Blood Pressure and Heart Rate

Blood Pressure and Heart Rate

Analysis: Page 345
2. Evidence that concluded exercise affects pulse rate is that in every trial after jogging the pulse rate was higher from the resting pulse rate. 4. The independent variable is the heart rate and exercising is the dependant variable. 5. An experimental error could have been the time in between exercising and taking the heart rate and blood pressure. For example after exercising when you take your blood pressure and heart rate there could be an ‘Error’ on the machine causing you to retake your heart rate and blood pressure and that time in between could affect the results. 6. A pulse rate can also be taken on your neck just under your ear. 7. The intensity of the pulse rate should be the same at each site. 8. The pulse right is taking on an artery.

9. The pulse is felt by the elasticity of the wall and the muscles that contract as the blood passes through. Page 348
1. No because some arteries are differing sizes,...
