Heart Rate Investigation

Aim:

To discover if there is any link between the amount of exercise taken

to the rise of a persons heart rate.

Prediction:

I predict that as the amount of time you exercise goes up so will your

heart rate. But after a certain amount of time your heart rates rate

of increase will slow down and eventually level out and stay the same,

until you slow down or stop exercising.

This is because the more you exercise the more energy your body will

need. Oxygen is pumped around the body in the blood, the heart pumps

the blood around the body so you have a higher heart rate while or

shortly after exercise as the heart is working harder pumping the

blood around the body.

Method:

· Start by setting up all the apparatus and put the trainers on and

tie securely.

· Take your resting heart rate. Lie down as you take it as you are

most rested lying down take it for 15 seconds and times it by 4,so

that it is the amount of beats per minute. Doing this will be more

accurate than taking the heart rate for 60 seconds at one go. As you

would be more likely to loose count of the number of heartbeats.

· Use the stopwatch to time 1,2,3,4 and 5 minutes of continuous

step-ups. After each different length session of step ups take your
