How Much of an Affect Does Exercise Have On Our Pulse Rate?

Fair testing: For this experiment to be fair we need to:

* Use the same person for all of the exercises.

* Do all the exercises on the same day so that the temperature of the room is exactly the same, and the person's diet is the same.

* Use the same type of exercise e.g. Step-ups on a PE bench.

* Use the same bench for all the exercises, so that the height does not influence our results.

* Take the pulse rate in the same way at the same pulse point e.g. the wrist.

The variable that will alternate as a result of this is pulse rate.

We will be changing the length of exercise we do.

Method:

.) I will take my pulse rate at rest three times, using two fingers on a pulse point. I will then count the beats per minute. After collating this information, I will then add all of the results together and divide them by three to give myself an average pulse rate.

2.) I will then do step-ups on a PE bench for 1 minute, then immediately after, take my pulse rate. (BPM)

3.) I will then rest until my pulse rate has recovered. I will then repeat step 1 to find my average 'pulse rate at rest'.

4.) I will then repeat step 2, but this time I will exercise for 2 min.

5.) I will repeat this procedure of exercising, recording my pulse rate, then resting. I will exercise for periods of time of: 1 min, 2 min, 3 min, 4 min, 5 min and 6 min, recording my pulse rate before and after exercise.

I will use a stop clock for accurate timing, and I will wear training shoes to prevent accidents while exercising.
