Heart Rate SurveyPurpose: To find out if there is a relationship between the amount of exercise performed and the increase in a person's heart rate. Prediction: I predict that as exercise duration increases, your heart rate will increase. But after a while, your heart rate will slow down and eventually stabilize and stay the same, until you slow down or stop exercising. This is because the more you exercise, the more energy your body will need. Oxygen is pumped throughout the body in the blood, the heart pumps blood throughout the body, resulting in a higher heart rate during or shortly after exercise as the heart works harder to pump the blood throughout the body.

Lie down while you take it, since you are most rested, take it for 15 seconds and multiply it by 4, so that is the number of beats per minute. Doing this will be more accurate than taking heart rate for 60 seconds straight. As you would be more likely to lose count of the number of heartbeats. · Use the stopwatch to time 1, 2, 3, 4 and 5 minutes of continuous increases. After each step up session of a different duration, take your
