Predictions
1. During exercise:
TV will increase.
2. During exercise:
IRV will increase.
3. During exercise:
ERV will increase.
4. During exercise:
VC will increase.
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. age; sex; height
4. Which respiratory volume was calculated?
TV, ERV, IRV, RV
5. What was the purpose of the nose clip?
To assure that all breathing would be done through the mouth

Comparison of Resting and Exercising Lung Volumes and Breathing Rate

1. Did the breathing rate increase, decrease, or not change with exercise? increase 2. Did the tidal volume increase, decrease, or not change with exercise? increase 3. Did the expiratory reserve volume increase, decrease, or not change with exercise? decrease 4. Did the inspiratory reserve volume increase, decrease, or not change with exercise? decrease 5. Did the inspiratory capacity increase, decrease, or not change with exercise? not change
6. Did the functional residual capacity increase, decrease, or not change with exercise? decrease 7. Did the minute ventilation increase, decrease, or not change with exercise? increase Table 3: Lung Capacities and Minute Ventilation
