Thacker 3/29/16 Lung Capacity and VO2 Max
Let’s face it. Big lungs aren’t sexy. You don’t see commercials on TV with
big-lunged people traipsing through an exclusive nightclub, and you don’t
generally brag about your lung size at parties. But if you have ever gotten
out of breath climbing a flight of stairs, become frustrated with your inability
to run up a hill during a 5K or marathon, or found yourself constantly sucking
oxygen on thetreadmillor in the gym, then you know that oxygen capacity is a
very important component of fitness. But the benefits don’t stop there, since
there’s a direct link between a higher oxygen capacity, and reduced risk of death!
You have learned all about the heart, how it works, how frequently it beats, the volume it puts out and about how breathing provides the oxygen to your body so ATP can be synthesized to provide energy for bodily functions. This in turn produces CO2 which needs to be eliminated by exhalation. The respiratory and cardiovascular systems work together to deliver oxygen to the tissues and remove carbon dioxide. Together this is thecardiopulmonary system.
We have very little control over the workings of our heart and lungs, however we can do a few things to help our hearts and lungsbe as productive and efficient as possible. Within this 3 week long project you are going to come up with a plan and implement an experiment to try and increase your VO2 max and/or lung capacity.
Objective: To design and conduct experiments over a three week time frame to determine if VO2max and/or lung capacity can be increased by various strategies.
You will need to:
1. Research lung capacity and VO2 max.
2. Devise a plan of exercise that you believe (due to your research and taking into consideration your own needs) could improve your VO2 max and lung capacity.
3. Formulate a testable hypothesis.
3. Keep a record of all observations and create a data chart to enter in your data for variables like exercise description, duration of exercise, time, starting heartbeat, ending heartbeat, starting respiration, ending respiration, duration of exercise, wt. in Kg
4. You will determine an average resting heartbeat and average resting respiration in class. You will also determine a maximum lung capacity volume in class.
5. You will determine a starting VO2 max in class following the procedure in this handout.
6. You will determine a final VO2 max in class at the end of the project during class.
7. You will record your data over a three week period and then summarize your results, create graphs, and hand in the report.
Start Date: Thursday 3/31/16 during class you will calculate your baseline readings of lung capacity, VO2 max, resting heartbeat and respiration and final heartbeat and respiration after exercise.
Final Date: Friday 4/22/16during class you will calculate your lung capacity, VO2 max, resting heartbeat and respiration and final heartbeat and respiration after exercise.
Final written report with data graphs and analysis is due on Tuesday April 26th.

VO2max/Lung Capacity Project Planning sheet: Initial recordings 3/31/16
Initial readings:
Resting Heart Rate( BPM) =______
Resting Respiration rate/minute=______
Lung Capacity (ml)(forced inspiration and forced expiration into bottle). Measured volume displaced=______
Replicates???
Formula 1 for calculating VO2max
VO2 max= 15.3 X (MHR/RHR)
MHR= maximum heart rate bpm using age 208-(0.7 X age) My MHR=______
RHR= resting heart rate bpm # of beats in 20 se. X 3 My RHR=______
My VO2 max= 15.3 X MHR/RHR= 15.3 X ______/______=
My VO2 max calculated using formula 1=
Formula 2 for calculating VO2 max is the Rockport Fitness Walking Test (RFWT) 1 mile
VO2 max = 132.853 - (0.0769 x W) - (0.3877 x A) + (6.315 x G) - (3.2649 x T) - (0.1565 x H)
W = Weight (in pounds)
A = Age (in years)
G = Gender factor, G = 0 for females and G = 1 for males
T = Time to complete the 1-mile walk (in minutes)
H = number of heart beats in 10 seconds at the end of the 1-mile walk
My Weight=______
Age =______
Gender=______
Time (m)for 1 mile______
Heartbeats at end of walk in 10 sec.______
VO2 max= 132.853- (0.0769 x W) - (0.3877 x A) + (6.315 x G) - (3.2649 x T) - (0.1565 x H)

1. How does the VO2 max from formula 1 compare to the VO2 max from formula 2?
2. Which formula do you think is more accurate? Why?
3. What is your exercise plan/other plan for trying to increase your VO2 max going to be?
4. How often are you going to do this?(minimum of 4X/week for 3 weeks)do you think more often would be better?
5. What is your hypothesis (the prediction of what you think will happen, started in an If-Then format that can be tested by your experimentation)?
6. What is your independent variable?
7. What is your dependent variable(that you will measure within your experiments)? (final dependent variable will be to determine your VO2 max via formula 2 on the last day and to take a lung capacity volume check on the last day as well)
8. What variables should remain constant? Which variables can you keep constant?
9. The initial and final readings of heartbeat, respiration and lung capacity should be taken how many times to determine a reliable initial and final reading? Did you do that???
10. What equipment, supplies, or facilities will you need? Where will you do your experimental trials?
11. What will you measure and keep track of in a data table? Draw an example of the headings of your data table here. List the types of graphs you can prepare from this data.
12. Meet with another group and discuss these plans. Describe any changes you made based on your collaboration.
Your Typed Report should contain:
Title:
Background section: explaining and describing VO2 max, lung capacity, and exercises to increase VO2.(this should be at least ½ pages in length)
Hypothesis:In an If…then statement.
Procedure:how youcarry out your “training”/experiment…all details
Results: data charts, written observations, Graphs (at least 2)
Analysis: This is where you describe your results in paragraph form explaining the results and formulating inferences and conclusions from supporting data.
Conclusion: This is a one sentence statement, either my data supports or does not support the hypothesis.
Reflections: This is where you describe issues you experienced that may have in some way affected the results, identify changes you would include to better the experiment and why the changes are helpful. You should include at least 2 new questions you now have after evaluating your data.
