Introduction

How does exercise affect heart rate? Aim The aim of this experiment is to investigate how exercise affects heart rate. I am going to record my resting heart rate, then exercise for 30 seconds , then 1 minute and increase the period of exercise by 30 seconds until I am exercising for three minutes without stopping . I will does this twice and take an average Prediction I predict that my heart rate will increase as a result of exercise. I think that there will be a slight increase to begin with, but as the body has to work harder I think that the heart will then increase at a faster rate. ...read more.

I will keep the exercise, step ups, the same. To keep it a fair test I will rest between each period of exercise to let my heart rate to return to my resting heart rate. Apparatus Timer, step Method Collect apparatus Record resting heart rate for 1 minute (arm, neck, temple, chest) Exercise for 30 seconds and record your heart rate Rest until your heart rate is as it was at resting Repeat this for each period of exercise increasing it y 30 seconds each time until your exercising for 3 minutes Do this experiment 3 times to get an average Results Time minutes 1st pulse bpm 2nd pulse 3rd pulse Average pulse 0 60 64 64 63 0.5 ...read more.

Conclusion

you exercise for longer periods of time as your muscles need more energy to work longer Evaluation My results were quite accurate although there was one anomalous point which didn't quite follow the straight line pattern (circled on the graph and table) this may because I rested to long and didn't start again on time. Because this was only found out from my averages I couldn't repeat it although if I had more time I would have liked to. If I could improve this experiment I would use a more intense exercise like running on a treadmill as I think this would be more accurate as you can keep the intensity the exact same for each period of exercise ...read more.

    This was in order to pump blood around the body quicker, supplying oxygen to these cells. Overall, pulse rate and intensity of exercise are proportional. The greater the intensity of exercise, the higher the body pulse rate is - after exercise.
