Exercise effects of heart rate

Problem

What type of exercise increases the heart rate the most?

Hypothosis

If we do jumping jacks for a minute, run up and down stairs for a minute, and up-downs for a minute, then running up and down the stairs will increase your heart rate the most, because the inclined and declined running uses the most energy.

Our research

Why does our heart rate speed up during excercise? Our pulse rate speeds up during exercise because our exercising muscles demand more oxygen and energy. Consequently our heart must beat faster in order to deliver it. The other reasons for increase in pulse rate are environmental temperature increases, dehydration and cardiovascular shift.


Exercising helps improve heart health and can also reverse some heart disease risk factors. The heart becomes stronger as a result of exercise, so it pumps more blood through the body. The resting heart rate of those who exercise is slower. A person who exercises often has the lowest risk for heart disease, therefore exercise is beneficial. Light to moderate exercise is also beneficial for the people with heart disease. However, anyone with heart disease or cardiac risk factors should seek medical advice before beginning a workout program. Exercising helps in cholesterol and fat levels, reducing inflammation in the arteries, helping weight loss programs, and helping to keep blood vessels flexible and open.

Conclusion

We claimed that if we do jumping jacks for a minute, run up and down stairs for a minute, and up-downs for a minute, then running up and down the stairs will increase your heart rate the most. As we did the experiment, our evidence shows that the average heart rate for doing jumping jacks is 226 beats per minute, for run up and down it is 204 beats per minute and for up - downs is 273 beats per minute. Our claim was proved wrong because doing up - downs made the heart rate go up the most. Our reasoning is that doing up - downs requires us to jump and then lay down on your stomach completely. This is very hard to do and uses much of our energy. Hence, it increase the heart rate the most.
