Heart Rate Recovery after Exercise

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.

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

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

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.

Heart Rate

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

Conclusion Page

The pulse did change during different typesPulse was greatest after Jumping JacksLowest after Jumping RopeThe heart rate of those who exercised

regularly had a faster recovery time
