Heart Rate

A detailed Summary of Heart Rate

The aim of this experiment is to find out how different intensities of exercise effect the heart rate I will measure it in beats per minute using a polar heart rate monitor.

I predict that as I increase the intensity of the exercise I do, that my heart rate will increase. This is because as I exercise more intensely I will need more blood to my muscles to supply oxygen and take away carbon dioxide; therefore my heart is going to have to beat faster to keep up with oxygen demand, so oxygen debt doesn't occur and so that carbon dioxide can be taken away as it is a waste product.

For this I can use one of three choices these are;-1. Work rate, as in the speed I will go on the running machine and change for different intensities.

-2. Time of work, meaning how long I will work for, and change for different time intensities.

-3. The work load I will run with. I could change this for different intensities.

I will use the work rate as my variable to manipulate; therefore I will be changing the speed at which I run in Km/h. This means that I will not change the time I work for or the work load I work with.

Some common words found in the essay are:
Values Ranges, Rate Aim, heart rate, running machine, carbon dioxide, polar heart, beats minute, heart rate monitor, polar heart rate, rate monitor, fair test, rate increases, rate measure, oxygen debt, exercise heart rate, link running machine, heart rate measure,
