Transcript of Heart Health: How Does Heart Rate Change with Exercise?

Thank You!
The materials I will need are
A stationary bike cost $ 50
A heart rate machine cost $ 15
Three people no cost

Why I was interested
I was interested in doing this experiment because it was about physical activity such as running and other sports . I like to play and watch sports that is one of the reasons. Another reason was I knew that I would have fun doing this project with my mom and sister.
I know that when you do jumping jacks your heart rate will increase more than running , walking , and cycling . So , when you do jumping jacks your heart rate increases because it is a high-impact exercise that requires you to jump while raising your arms and opening your legs. For every jump you land, you contract the muscles in the lower body, so building strength. So it will increase your heart rate more than the other three activities.

Background research
A child's heart rate is dependent upon the age. A child of 3 or 4 should have an exercising heart rate of around 137 beats per minute. By 5 to 7 years old, the heart rate drops to just 133 beats per minute. From 8 to 11, it is even lower, 130 beats per minute. Finally, in adolescence, the exercising heart rate is significantly lower. A 12- to 15-year-old only needs to get their heart rate to 115 beats per minute when exercising

The definition of the word heart rate is The number of heartbeats per unit of time, usually expressed as beats per minute.A question I had was how does age affect your target heart rate after exercise. Your heart expands and contracts for every heart beat. Richard Schulz, PhD, explains in "The Encyclopedia of Aging: Fourth Edition" that your heart loses its elasticity as you age, resulting in weaker expansions and contractions.

The activities that increase your heart rate more than other activities.If you play physical sports such as football and basketball you run a lot and and tackle then your heart rate will be a lot higher. Some mathematical formulas I will have to do are find the difference between the resting heart rate and the heart rate after the physical activities. The independent variable of my project is the activities, the dependent is the participants and the control is the heart rate for every person.
The Results
The results of my experiment was the activity that changed our heart rate the most was the running. I know my hypothesis is incorrect because when I checked my results and I subtracted each of the heart rates after activities with the resting heart rates and I found out how much our heart rates went up. It went up the most for the running.

What I learned from my experiment was how different types of exercises change your heart rate and how your age can affect you heart rate as well.

How Does Heart Rate Change with Exercise? The purpose of this experiment was to see which physical activities would increase your heart rate the most. I saw that my hypothesis was incorrect when I checked the difference of the heart rate from the resting heart rate to the heart rate after the activities, for the running the heart rate increased the most of myself and my mom.

I can tell from my research because in my background research I learned that jumping jacks increase your heart rate more because your whole body is moving your legs ,arms and stomach. I also learned that running might increase it more because when you run running increases heart rate because oxygen is demanded more when body is exercising, the quantity of work of the muscles depends of the volume of blood delivered by the heart . That is why running increases your heart rate more .
Tables and Graphs
How I did this project is I took my mom and my sister and every day we did one of the activities. So we ran one day , did jumping jacks the other , walked the another day and bicycling the last day. We did each activities for five minuets each. After we did each of the activities we checked our heart beats on a electronic device. After that we wrote it on our table.We did that every day until our project was finished. At the end we analyzed the numbers and made graphs and charts.
These graphs are our heart rate after the four activities
These tables are our heart rate differences from the resting to the heart rate after the activities.
