Respiratory Volumes
Predictions
1. During exercise: TV will increase. 2. During exercise: IRV will decrease. 3. During exercise: ERV will increase. 4. During exercise: VC will not change. 5. During exercise: TLC will not change.
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.

Comparison of Resting and Exercising Lung Volumes and Breathing Rate
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
