Predictions – (increase/decrease/remain constant/not change) 1. During exercise: TV will increase. 2. During exercise: IRV will decrease. 3. During exercise: ERV will decrease. 4. During exercise: VC will not change. 5. During exercise: TLC will not change. Materials and Methods 1. Dependent Variable. The dependent variable is the respiratory volume. 2. Independent Variable. The independent variable is the level of physical activity. 3. Controlled Variables. The controlled variables are the age, gender, height, weight, and physical health of the subject. 4. Which respiratory volume was calculated? The respiratory volume that was calculated was TLC. 5. What was the purpose of the nose clip? The purpose of the nose clip was to prevent air from leaking out of the nose.
