How does recovery position affect recovery rate?

How does Recovery Position affect Recovery Rate? Introduction Evidence from modular science shows an athlete in a recovery position (page 11). In this position they can take more oxygen into her lungs, because their surface area is increased. However is this position better than any other position. Scientific Explanation To stay alive we all need oxygen. The breathing system is working all the time to provide a continued supply of oxygen to the healthy body. During exercise we need even more oxygen than usual. During strenuous exercise lactic acid is produced by anaerobic respiration. This causes muscles to become tired and they work less efficiently. To make sure this doesn't happen lactic acid needs to be removed by using oxygen to break it down. After exercise you often keep breathing heavily to take in extra oxygen. The recovery position after exercise will also help you take in extra oxygen because in will increase the surface area of the lungs allowing a greater volume of oxygen in the lungs. The surface area of the small balloons together is greater than the surface are of the on large balloon even though they have the same volume of air. These are the results of an investigation carried out by modular science to find out how breathing patterns change during exercise. Activity Volume of each breath (Cm) ...read more.


To make the results more accurate we will use secondary data. The only equipment we will use is a stopwatch. Fair Test To make it a fair test we will use secondary data. We will keep the following things the same: Time you do exercise in, recorder, person carry out the exercise and the equipment we use. We will change the recovery position. We also did a pilot test to see what problems aroused and see how the investigation could be fairer. Results Primary Results Recovery Positions Strenuous Exercise Breathing Rate Before Breathing Rate After Difference Between Two Time to Recover(mins) Standing 1 min 20 28, 22, 20 6, 2, 8 3 min Sitting 1 min 24 32, 30, 24 2, 6, 8 3 min Bent Over 1 min 27 36, 27 9 2 min Crouching 1 min 26 36, 30, 26 6, 4, 10 3 min Lying Down 1 min 24 30, 24 6 2 min Secondary Results Recovery Positions Strenuous Exercise Breathing Rate Before Breathing Rate After Difference Between Two Time to Recover(mins) Standing 1 min 31 47, 35, 31 12, 4, 16 3 min Sitting 1 min 27 38, 27 11 2 min Bent Over 1 min 35 35 0 1 min Crouching 1 min 29 40, 29 11 2 min Lying Down 1 min 31 36, 31 5 2 min Conclusion I conclude that the best recovery position after strenuous exercise is bending over (see primary and secondary tables and graphs). ...read more.


Evaluation My results were fairly accurate because I used both primary and secondary data. I also carried out a pilot before hand to see what problems might arise and to make my data more accurate. There did not seem to be any odd results for either primary of secondary data. However because this investigation involved testing humans none of the results can be entirely accurate because different humans react and behave differently in the same situation I do not think the method I used was the best method for testing recovery positions because the person you were testing began to get tired after a while. I believe we could have solved this problem by leaving a large amount of time between testing these five recovery positions, however we did not have the time. I also think our results would be more accurate if we had tested a larger number of people and a larger number of recovery positions however again we did not have the time. To extent this investigation we could test different types of people, for example; age and gender could have and effect on what is the best recovery position to take after strenuous exercise. I could also further investigate how to get rid of lactic acid in the quickest time possible or how to reduce the build or lactic acid because these affect recovery rate. ...read more.
