LABORATORY REPORT (Click on the Save a Copy button on the panel above to save your report) Activity: Name: Instructor: Date: 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…show more content…
7. Did the minute ventilation increase, decrease, or not change with exercise? of course the minute ventilation increase tremendously after exercising. Table 3: Lung Capacities and Minute Ventilation Breathing Rate 2.6 2.9 3 2.8 TV(L) 2.9 3 2.9 2.9 Resting Values ERV(L) IRV(L) 3.9 4.3 4.3 4.2 5.5 5.9 5.9 5.8 RV(L) 3.4 3.6 3.7 3.6 Breathing Rate 2.2 2.3 2.3 2.3 TV(L) 4 4.3 4.4 4.2 Exercising Values ERV(L) IRV(L) 5.6 5.9 6 5.8 6.2 5.3 6.7 6.1 RV(L) 42.2 50.2 49.5 47.3 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. the vital capacity remain the same because it accumulated the tidal
