Cycling is a form of exercise known to increase the heart rate. For cycling, four incline levels typically determine how much more intense you would like the workout to be. Level one is a walking pace, two is slightly more difficult, three is like cycling up a hill, and four is the most intense like cycling up a mountain. I will test the heart rate to see how it increases or decreases depending on each incline level. The moderate activity would be levels one and two, while the strenuous activity would be levels three and four. Before beginning the exercise, I will sit on the bike in a resting position to get my resting heart rate. Then I will start the stopwatch on the bike that records my cycling time, heart rate, and RPM (revolutions per minute). I will start at level one for five minutes and then record my heart rate after the session. I will rest for five minutes and then repeat the same process for each incline level (three more times; four in total). What may be the independent, dependent, and controlled variables in the experiment?
