Respiration At Rest Versus Exercising
Respiration at Rest versus Exercising
This is a Hands-On Labs experiment that explores the differences in respiration at rest and during exercise. Before you start, watch the following videos to become more familiar with the lungs. The first video is narrated using basic terminology, so it is easier for the viewer to understand. The second video is more extensive, showing more structures of the lungs, including the diaphragm. This video also shows the placement of the liver and reviews the structures of the heart.

Procedure
Follow the procedures detailed in the Respiratory Physiology experiment from Hands-On labs. During the lab, you will breathe into a balloon while you are resting to record how much air is in a single exhalation at rest. You will then exercise for a bit and assess how much air you exhale when you are active. Be sure to follow the instructions in the lab to complete the experiment. Record your data and calculate your tidal volume, minute ventilation, forced vital capacity, and total lung volume. When you are done, write a report or create a presentation. You do not need to submit the Lab Report Assistant for grading.
Create a Report
Use the following outline to describe the data from your lab in a report. Label each portion of the lab as described below.
Introduction: Start with a broad discussion of the lungs, and then narrow your focus to the question(s) that you are trying to answer. Include any observations or background information about the lungs that may pertain to the lab. Conclude the introduction with a hypothesis—a statement that reflects what you believe the outcome of this lab will be. What are you comparing and what do you expect will happen?
Material List: Identify all items that you used and the exact quantities, as applicable. This may be a very short section.
Methods: Describe how you conducted the experiment, including any safety precautions you took while performing the lab. Be sure to include any changes that you made to the original instructions. Did you use different exercises? This should be a short, paraphrased version of the methods from the lab. Do not copy from the lab; Turnitin will highlight it as plagiarism.
Results/Data: Create a table or a figure that reflects/compares the results of your experiment.
Discussion: Review your results and determine if your experiment supports or refutes your hypothesis. Explain why. Then expand your discussion to address why and how your body creates the changes you observed as you increased your level of activity. Be specific and give details. What impact would changes to your lifestyle, such as increasing or decreasing your regular level of activity, have on the values you calculated?
Conclusion: End with a section describing something that intrigued you about the lab; identify errors that may have impacted your results, or note errors in the lab itself; and provide recommendations for future labs.
Requirements:
If you are doing the report, it should be 4-5 pages long, not including the title page.
Reference at least two journal articles.
Include a title page, or title slide for the presentation, and references at the end.
Follow the CSU-Global Guide to Writing and APA.
