Question
How does the pace of a run affect the breathing rate per minute after a two minute run?
Problem statement
The purpose of this lab is to decipher if a runner’s breathing rate will increase, decrease, or remain the same according to the pace the runner sets. The independent variable is the pace; the runner will run at 12 minutes per mile, 10 minutes per mile then 8 minutes per mile. The dependent variable is how many times the runner breathes per minute directly after the run. The constants of this experiment are the subject, the environment and the length of time running. In order to keep these variables constant, the subject will run on a treadmill. This will keep the three different paces constant along with the amount of time running and the surface of the area being run on will not change. Also the treadmill is indoors with the air temperature staying at a consistent level.
