The effect of exercise on the body

Variables

I'm going to investigate the effect of exercise on the body. I could investigate the amount of perspiration, the breathing rate or the heart rate. I am going to investigate how exercise effects my pulse rate because I can investigate this more accurately.

Step-by-Step plan

* First of all I will take my resting pulse rate for a minute.

* I will then do step-ups at a constant rate for 1 minute.

* After, I will take my pulse rate again for 1 minute.

* Then I will allow pulse rate to return to normal.

* I will then do step-ups for 2 minutes.

* Take pulse rate again for 1 minute.

* Repeat experiment, going up in consecutive numbers until doing step-ups for 5 minutes.

* Repeat experiment three times.

Equipment

I will use a step, a stopwatch, and I will also wear trainers.

Fair test

I will make the test fair by controlling the variables I'm not investigating

* I will change the amount of time doing exercise.
