  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 • Take pulse • 2 minute wait • Run for 1 minute • Take pulse

  8. Procedure Cont’d Variables 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 AVERAGE 78 104.8 108.2 114

  10. Graph There is a bar for each person. The bars represent the pulse of the person after running.

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

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

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

  14. Graph 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 • I believe that the outcome would have been different if I took the pulse right away after each exercise instead of waiting a minute for the machine to find the pulse.
