Procedure:

1. Rest for 5 minutes – sit and do nothing!
2. Count your breaths per 30 seconds.  Take your BP and HR.
3. Run for 5 minutes
4. Count your breaths per 30 seconds.  Take your BP and HR.
5. Rest for 5 minutes, take vitals.
6. Continue to rest, take vitals in 5 minutes
7. Continue to rest, take vitals in 5 minutes… (15 minutes of rest.)

Questions:

1. Graph your results.  Graph 1 – Put BP on the y-axis left side and HR on the right side, and time (experience) on the x axis.  Graph 2 – Put Breath Rate (per minute) on the y-axis left side and HR on the right side, and time (experience) on the x axis.
2. How does your recovery time compare with the recovery time of others in your group?
3. Explain the reason for the breath rate, pulse and blood pressure changes.
4. How does recovery time indicate level of fitness? Explain.
5. Research to find the normal rates for a person your age. How does your pulse rate compare? What are some of the reasons for the differences?
6. Describe any difficulties you had with running this lab. Is there anything that you would do differently?

Extension:

1. What organs are involved when we exercise?
2. How are they related?
3. Draw out the organ system that is involved in exercise.  On your diagram outline the role each organ plays in the system.
4. Thinking about the ‘One Life… Many Gifts’ stories – think about Cystic Fibrous – and the daily need for oxygen!  Write a paragraph in response to how you would deal with an issue like CF, how it would affect your life.  What might you have to give up or modify in order to live.  Post on your wall.  Comment to at least 2 other people (useful and constructive comments only).
