Investigation into how exercise affects the body.

Introduction

Investigation into how exercise affects the body Plan We are investigating how exercise affects the body. We could complete this experiment in a number of ways; the results could also be measured in any of the following: Heart Rate: - amount of time the heart beats per minute Breathing Rate: - amount of breathes per minute Recovery Rate: - How long it takes for the heart rate to return to resting rate. The experiment we have chosen involves measuring the heart rate. From previous experiments we have decided that the heart rate will be the best as it is the easiest to measure in a classroom experiment. Prediction I predict that as the body exercises the heart rate will increase. ...read more.

A step up and down should be as followed: * Step up with on foot * Step up with the other to stand straight * Step down with the leading foot * Step down with the other to the original starting position Take pulse for 1 minute and compare with original Diagram Results Resting Heart rate After exercise Heart rate 60 70 60 65 70 72 Average Resting Heart rate Average After exercise Heart rate 63 69 Graph Conclusion From the graph you can see that my prediction was correct in the fact that the heart rate does increase as the body exercises. As the body exercises the muscle cells in your body need more oxygen so that they are able to work for longer and quicker. ...read more.

Conclusion

However, if I were to do this experiment again, I would make the following two changes: * Conditions: I would do the experiment in a controlled environment where the conditions could not change so that I knew for sure that there was no way that my investigation could differ each time. * Equipment: I would use a heart rate monitor as used in hospitals so that I could get more accurate results than by just determining my own pulse by using my hands to find my pulse. The problem with doing the experiment in classroom environment is that there are many ways in which the experiment can be tampered with so that it is not accurate. Ideally all experiments would be done in controlled conditions using computers that can be programmed to do the same things exactly the same over and over again. GCSE Biology Joe Smith ...read more.

    Therefore, I will take certain measures on these. * Size of potato strips - a larger surface area will take longer for the molecules to go through. * Size of beaker - molecules will collide more often making the process longer * Temperature of water - molecules moving faster giving also more collisions also if too hot evaporation

    The reason why I think this is because the more ethanol and caffeine you use the more affect it may have on the nervous system. Variables: There are a number of variables in my experiment that if was changed would vary the results.

    The graph shows that the pulse rate of students A is 74 at resting position and for student B it is 80 at resting position. As they exercised my graph shows that the pulse rate started to increase at a steady level for both students up till 3 minutes.
