1. Heart Rate Recovery after Exercise
RACHEL C. CLINTON
GRADE 9

2. Problem Page
Does heart rate change during different types of exercise?
The purpose of this experiment was to see which exercise is a better workout.

3. Research Page Heart located in center of chest
Heart is shaped like an upside-down pear
4 cavities or open areas that are filled with blood
Two are called atria
other two are called ventricles
There is one atrium and one ventricle on the left side
one atrium and one ventricle on the right side
A wall called the septum separates the two sides of the heart
There are valves that connect the atrium and ventricle to each other
There are two important blood vessels
one called the aorta which carries the blood away from the heart and
Other called the pulmonary artery which connects heart with lungs

4. Research Cont’d
Exercise prevents heart disease and other heart problems
Pulse increases during exercise because the body needs more oxygen
For the muscles to work they need oxygen
The longer you exercise the more oxygen your muscles need
Pulse increases to get oxygen to the muscles so they continue working
Working muscles take oxygen out of the blood three times as fast then when they aren’t working
Your maximum heart rate is 220 minus your age

5. Hypothesis Page
I think the heart will take different amounts of time to recover depending on the type of exercise.
I also think that the recovery time will be faster for those who get regular exercise.
I believe this because those who exercise more, their muscles are used to trying to get oxygen out of the blood quickly, while the muscles of those who don’t exercise regularly aren’t used to it.

6. Materials Page
Automatic blood pressure machine
Stopwatch
Jump rope

7. Procedure Page Take initial pulse Jumping jacks for 1 minute
Take pulse
2 minute wait
Jump rope for 1 minute
Run for 1 minute

8. Procedure Cont’d Variables Control: Constant:
Independent Variable: is whether or not the person exercises regularly
Dependant Variable: hear rate
Control:
No exercise
Constant:
The type of exercise
amount of time
automatic blood pressure machine

9. Data Regular Jump Rope Running Jumping Jacks Person 1 83 126 132 11586
120
104
Person 3 63 81
118
113
Person 4 62 80 90
Person 5 96
105 95
AVERAGE

10. Graph Whats on x y and what is measured and what people r looking at
There is a bar for each person. The bars represent the pulse of the person after running.

11. The bars represent the persons pulse after jump roping.

12. The bars represent the pulse of the person after doing jumping jacks.

13. The bars represent the person’s regular pulse.

14. This graph represents the average heart rate for each person’s regular heart rate and the average of the heart rates after exercise.

15. Conclusion Page The pulse did change during different types
Pulse was greatest after Jumping Jacks
Lowest after Jumping Rope
The heart rate of those who exercised regularly had a faster recovery time
