This experiment's goal is to find out if people who exercise regularly are truly fitter than those who don't exercise regularly. Since a person's level of cardiovascular fitness can be measured through his/her heart rates, we believe that the people who are fitter will need less time to return to resting rate after exercise.
[...] After we gathered our materials, we started the experiment by following these steps: First, we find two subjects who differed in that one exercise regularly and the other doesn't exercise regularly. Then, both subjects measured their resting rates by checking their pulses, which is an easy and effective way to determine their resting heart rates. The subjects used their first and second fingers and pressed them gently to their throats. Then, as they started counting the beats, the timer used the stop watch to time them for 30 seconds. [...]
[...] Then, the length of time it took for both subjects to recover were recorded in the “Recovery” section of the results table. To ensure a controlled experiment, the exercise conditions for the experiment were identical for both subjects. Both subjects exercised on the same exercise step simultaneously at the same time and at the same rate. Also, their pulses were taken at the same time. The independent variable of this experiment would be the selection of subjects based on only their different exercising habits. One subjects exercises regularly while the other one doesn't. [...]
