Investigation to compare Candidates Pulse Rates After Exercise.

Extracts from this document...

Introduction

Investigation to compare Candidates Pulse Rates After Exercise Planning: AIM: To compare candidates Pulse Rates after doing 2-4mins of Exercise, involving Jogging, Star Jumps, and Step-Ups. EQUIPMENT: * Stop Clock * 6 Candidates including Myself * Clip Board * Table of Results METHOD: 1. Take each candidate, and one by one take his or her resting Pulse Rate. 2. Record this into the table of results recorded before the investigation began. 3. How after completing the above tasks, take each candidate and make them Jog on the Spot for 1min. 4. After 1min has passed take their pulse rate from either an artery in the neck or their wrist. 5. Take their pulse rate for 30secs, and times it by 2 6. Now what ever each candidate obtains, record this into the table, under the column called Jogging. 7. Now repeat the above instructions except make each candidate do Step-Ups, followed by Star Jumps, and Record the results into the table. 8. Remember to repeat the experiment so as to eliminate any anonymous results. FAIRTESTING: I plan to keep the range of results eg: the amount of time that each candidate participates in each type of general exercise, in this case 1minute. ...read more.

This is shown throughout all my graphs. This is done via an average. The pulse rate increases as the exercise becomes more vigorous. This in my case is not over a period of time but the type of exercise done. In this case the most demanding was Star Jumps, because the pulse rate is higher for this type of exercise than any other. (Done on Average). Star Jumps, was the most demanding for all my candidates. Pulse Rate measures how fast blood is being pumped around the body. The job of the heart is to pump this blood around the body. The heart is the size of a grown mans' two fists together. It is made up of muscle called Cardiac Muscles. The Heart acts like a pump, which pumps the blood with oxygen or with out around the body, to the needy organs. The blood has two main jobs; Transport and Defence. The oxygen is need for an important reaction that is used to make energy. ...read more.

Conclusion

I had a few results that I wouldn't call odd, but possibly miss interrupted. For all of my candidates, looking at Step Ups, for each test all the candidates had the same result for both Test 1, and Test 2. This may have been that all of the candidates took this type of exercise at the same pace as they did in Test 1 and Test 2. By this I mean that they were going up and down the step at the same sort of pace, there fore resulting in identical results. It may have also been that the step height never changed for Step-Ups. The results for all the other types of where all different, for test 1, and Test 2. This may have been to do with the effort that each candidate was putting into this type of exercise. (Jogging At A Different Speed). If I were to do the experiment again then I would improve where the test actually took place, for example: a hall of some sort. I think that if I were to do this them I feel that I may get more reliable results, because the temperature in the hall is almost staying the same. I could also get more results by using more candidates; this would then mean that I could, have 'more' evidence to put towards proving my prediction. ...read more.

    So because of this they believe that there is no need for using cow or pig for insulin. Genetic engineered insulin is good as it is made to ensure that there is enough insulin for all who need it. The insulin produced by genetic engineering is identical to human insulin which is an added advantage of this process.
