Materials and Methods

1. Dependent Variable. respiratory volumes

2. Independent Variable. level of physical activity [resting or exercising]

3. Controlled Variables. height; age; sex

4. Which respiratory volume was calculated?

Breating rate, TV, ERV, and IRV.

5. What was the purpose of the nose clip? the nose clip was used for the lung function testing to prevent leakage with the nasal compartments when giving respiratory volumes to be tested.

1. Did the breathing rate increase, decrease, or not change with exercise? the breathing rate increased tremendously since the subject did exercise and run.

2. Did the tidal volume increase, decrease, or not change with exercise? The tidal volume increase after exercising.

3. Did the expiratory reserve volume increase, decrease, or not change with exercise? The expiratory reserve volume decrease with exercise.

4. Did the inspiratory reserve volume increase, decrease, or not change with exercise?

The inspiratory reserve volume dercrese as well after exercising.

5. Did the inspiratory capacity increase, decrease, or not change with exercise? the inspiratory capacity increase just a little bit with exercise.

6. Did the functional residual capacity increase, decrease, or not change with exercise? the Functional residual capacity actually decrease after exercising.

7. Did the minute ventilation increase, decrease, or not change with exercise? of course the minute ventilation increase tremendously after exercising.

Subject1 Subject2 Subject3 Averages Comparison of Resting and Exercising Lung Capacities and Minute Ventilation Discussion

1. Explain the change in ERV with exercise. the ERV decrease with exercise asssuming that the volume of air was exhaled more than being enhaled at the time.

2. Explain the change in IRV with exercise.

IRV decreased as well because the amount of air that was supposed to be inhale was very little inhalation during the time of exercising.

3. Explain the change in IC with exercise. IC increase with exercise beacause the subjects were able to allow their lungs to breath.

4. Explain the change in FRC with exercise. The FRC decrease just a little with exercise.

5. Explain why RV does not change with exercise. the ERV decrease with exercise asssuming that the volume of air was exhaled more than being enhaled at the time.

6. Explain why VC does not change with exercise. he vital capacity remain the same because it accumulated the tidal volume, insipratory reserve volume and espiratory volume as well with exercise.

7. Explain why TLC does not change with exercise. RTLC did not change as well because the the vitaln capacity did not change and so did the residual vloume residual volume as well remain the same so calculations did not change vewtween these three subjects.

8. During exercise, the depth of respiration increases Name the muscles involved in increasing the depth of respiration and explain how muscle contraction causes this increase. he muscles involved in increasing the depth of respiration was the diaphragm, the lungs, the intercostal muscles, musles of insipration and expiration as well. Muscle contraction caused the increase becacause of the diaphragm.

9. Explain the importance of the change in minute ventilation with exercise. the change in minute ventilation after exercising increase tremendouly because the TV and breating rate increse the minute ventilkation which increased more breaths needed while running to meet a higher deman for oxygen.

10. Restate your predictions that were correct and give data from your experiment that support them.

Restate your predictions that were not correct and correct them with supporting data from your experiment. Accoriding to my predictions I only have one that is wrong and that is that the ERV will increasw with exercise but after testing subjects and doing the experiment it has be confirmed that the ERV decrese, so my assumption was by far wrong. But as for my other predictions it came out to be true according to the experiment, table and graphs, my assumptions was correct as for these subjects after exercising. Application Minute Ventilation will tend to increase for the simple fact it is the amount if ixygen inspired by the body in a minute. ncreased by long term exercise because over time it will adapt to bringing more oxygen to the lungs to work the muscles. 1. During strenuous exercise, TV plateaus at about 60% of VC but minute ventilation continues to increase. Explain how that would occur. an increase in residual volume, and assumming that the TLC does not change with a persom with developing emphysema will become short of breath after climibing a flight if stairs will result in the minute if ventilations being obtain while proceeding this type of exercise.
