An investigation into how harder exercise makes your pulse rate change.

Aim The aim of this investigation is to see how different intensities of exercise affect the pulse rate. I will also link this to the amount of work done and energy used, and see if there is a pattern.

Plan In the experiment we are first of all taking a measurement of the resting pulse rate, then taking the pulse rate after different intensities of exercise. All of these readings I will do 3 times and take an average, so it will be more valid, and I can distinguish which of the results are anomalous and which fit the trend so I can correct it. We will use skipping ropes to exercise and a stopwatch to time the exercise and to time a recovery period in between. I will skip for ½ a minute, then 1 minute then 1 ½minutes, 2 minutes, 2½minutes then 3 minutes.

To make sure that this test is safe, I will make sure that the ropes are not too long, so that people do not trip. As the test is being held outside, I will make sure that people are not too close to the pond incase they trip and fall in, and there are no sharp objects, bumps or cracks in the pavements which could cause injury. I will warm up before I exercise so I do not pull any muscles or cause any injury, and warm down afterwards.

To make this a fair test I will take 3 sets of results and take an average, to make the test more reliable. From this I can eliminate any anomalous results from my test. I will make sure that after each exercise my pulse rate returns to its resting rate before i continue, if...
