Biology Coursework – What affect does exercise have on our pulse?
Aim:
To find out what affect exercise has on our pulse by doing either different types of exercise or the same exercise for different lengths of time.
Prediction:
I predict that the longer you exercise the higher your pulse will get to a certain point where it will become steady, creating a smooth curve on a graph.
Equipment:
- Stopwatch – to time when I exercise and when I take my pulse.
- Area to exercise in / Treadmill – depending which is available.
Method:
For this test I will be jogging for a certain amount of time, taking my pulse for 15sec then jogging for the same time again without resting so the time builds up. This is how I will do my test:
- Start the stopwatch and jog for 30sec.
- Start the stopwatch and take pulse for 15sec.
- Then repeat until I have jogged for 5min in total.
- Multiply all my readings by 4 to get a bpm (beats per minute) pulse rate
- Repeat 1-4 3 times and work out an average to get a fair result
