The table above shows the relationship between the lung capacity average of people who do exercise constantly and the subjects who doses ‘t exercise often. As it can be observed, the blue column (represented by the average of athlete people) shows a clearly advantage above the red column (represented by the average of other subjects), that’s why it can be determined that the athlete’s total lung capacity in each ample performed was always higher than other person’s average.
Conclusion As the results clearly show, we can see that athlete people have much more lung capacity that people who doses ;t do exercise often, this is due because there is a correlation between lung capacity and athletes. Athletes are able to better manage their air intake thanks to the lung capacity. The heavy breathing that comes from practicing and competing aids in the process as well. Also A vital capacity of an athlete is higher than a non-athlete because they are trained to do hard work so their Eng get’s bigger overtime and makes it easier for them to take long breaths when they are running or doing any other exercise.
While non athlete’s doses ;t have their lungs trained and so their lung capacity don ‘t increase because they doesn’t have that need. X’. Evaluation It’s important to take into consideration that there exists many external factors that may alter the original results, such as not being precise enough when performing the lab, in many cases the position in which you are lying or standing might affect your total lung capacity. However, I controlled this the more I could by working with the people in the same position and with the same factors such as smokers and not smokers, and trying to reduce the error the most.
When repeating each performance make sure you do it in the same circumstances in order to avoid variability between data and at the same time achieve concordance between data. Weaknesses and limitations I Suggested Improvements I Variability of data I The data may vary considering the position, subject age or temperature at which the balloon is blown. However since I realize the experiment with the same conditions the data doesn’t vary a lot. I In order to reduce this errors al the process I recommend to do realize the experiment in the same room with the same temperature and with subjects of the same age in order to reduce the error.
I Systematic errors I Systematic errors may affect the results such as the instrument at which the level of water is measured or the materials of the balloon. In this case the instrument doses ‘t affect a lot the results however, the main error could happen at the moment when the water was trespassed from the tray since I spill some I I suggest take careful measures and avoid seeing the measure of the amount of water collected in iterant angles, and in this way avoid systematic errors and also be careful at the moment of displaced the water from the tray.
