The effect of exercise on pulse rate
Extracts from this document...
Introduction
Task: The effect of exercise on pulse rate Prediction: I predict that the more exercise I do, the higher my pulse rate will be. This is because our muscles need more oxygen to be pumped to them. Therefore the heart must beat faster to get more blood to the muscles. I also predict that my recovery rate will increase because my heart will be working to get muscles back to their original state. Method/Plan I am going to run at a jogging pace at different amounts of times. I am going to first run for 2 minutes then 4 minutes and then 6 minutes to see what affect it has on my pulse rate. I am going to measure my pulse rate for the first 2 minutes and note it down. ...read more.
Middle
This could affect my results because muscles and our body seemingly work better when they are warm than they do in cold weather. Another reason is that it will be very hard to keep the same pace when running each time I do the experiment, I will also become tired and possibly slow down during the longer exercises. Many other things could affect whether it is a fair test or not e.g. laughing or the person running falling over because this would make the pulse rate rise dramatically because of excitement or shock. The main reason for unreliability on the recovery rate side of it is that in the 30 seconds I am reading my pulse rate I am recovering then also. ...read more.
Conclusion
per minute After 2 minutes of running= 122 beats per minute After 4 minutes of running=136 beats per minute After 6 minutes of running=158 beats per minute Comparing Iain's and my results, you can see that over all I am a fitter person of us both. This could be because I play football every weekend and generally a more active and energetic person than Iain, which shows that exercise has a long term affect on your heart which makes it more efficient and used to copping with exercise. My average for the amount of minutes it takes for my pulse to return to normal rate is about 3.6 when Iain's is 5. I also seem to be fitter than jermaine according to the results, this could be because jermaine smokes and so his pulse has to work harder to keep him going. ...read more.
