‘Does Exercise increase the heart rate and recovery pulse?’

What am I trying to find out?

In this investigation I am trying to find out if the increase of exercise, affects the heart rate and recovery rate.

How will I carry out this investigation?

  1. Firstly I will take my resting pulse for 1 minute, (which I shall take before every period of exercise that I do)

  1. I will then run between 2 posts 20 metres apart for an amount of time. (either 30secs, 1min, 2mins, 3mins, 4mins)

  1. Once I have carried out the period of exercise I will take my pulse for 1 minute to get my heart rate.

  1. I will then take my pulse every minute after the exercise was completed, until my heart rate is back to its resting pulse.

  1. I will then continue repeating this method until all the times have been carried out 3 times.

  1. Once this has happened I will work out an average for each amount of exercise.

What equipment do I need in order to carry out this investigation?

  1. Stopwatch
  2. Trainers

How am I going to make this experiment a fair test?

To get a fair test I will do the following things:

  1. I will do each period of exercise 3 times, to get an average.
  2. I will stick to the period of time that I have agreed to do.
  3. I will put as much effort in to each section of exercise on all occasions.
  4. I will exercise on the same surface.
  5. I will take down the true results and not implant any false ones.
  6. I will always take down my starting pulse before every period of exercise.
  7. I will keep the distance between the 2 posts the same.

Is there anything that I will change during my investigation?

The only thing that I will change during this investigation is the period of time that I exercise for.

So what do I think will happen?

I predict that the heart rate will increase when you exercise. I also think that the longer you exercise for the higher your heart rate will become.

 

I also predict that the longer you exercise for, the longer it will take the recovery pulse to return to the resting pulse.

Why do I think this is going ...
