The Effect of Walking, Skipping, and Running on the Heart Rate Due Date: Friday, November 23rd, 2012
Question:
What is the effect of walking, skipping, and running on a person’s heart rate? Hypothesis:
If the intensity of the action increases (walking<skipping<running), then the heart rate will also increase because the faster the legs are moving, the faster the leg muscles need to contract. When the leg muscles contract faster, more energy is used, and the heart will pump faster to deliver oxygen through the blood stream to muscles, organs, and organ systems that need it in order for cellular respiration to occur. Variables:

The independent variables for this experiment are the 3 actions that will be carried out by test subjects: walking, skipping, and running. The dependent variable is the heart rate of each test subject (measured by number of beats per minute). The controlled variables include the temperature of the hallway where the experiment is being conducted, which is at room temperature; the amount of time each action is to be completed (1 minute), timed with a stopwatch; the amount of time each subject’s heart rate is measured for (15 seconds), timed with a stopwatch; the amount of time allotted for the subject to rest in between each action (1 minute), timed with a stopwatch; using the same method of measuring heart rate (having test subjects count the number of beats they can detect with their fingers); having the test subjects remove backpacks and heavy sweaters that can cause extra exertion; having the test subjects perform each action on the same terrain (the 2nd floor hallway); and completing all testing on the same day.

Materials:
-stopwatch -pencil
-5 test subjects -paper (w/ observation table)

Procedure:
1) Ensure that the 5 test subjects remove backpacks, heavy sweaters, or anything that will weigh the subjects down and cause extra exertion. 2) Have each subject find and measure the heart rate that can be detected by their fingers for 15 seconds, timed with the stopwatch. Record on the first observation table. Allow the test subjects 1 minute of rest while recording physical observations of the test subjects in the second observation table. 3) Have each test subject walk the designated hallway for 1 minute, timed with the stopwatch. Then, repeat step 2. 4) Repeat step 3, but substitute walking with skipping.

5) Repeat step 3, but substitute walking with running.
