Design an Experiment to show how exercise can affect Heart Rate in Humans Results: The experiment was carried out but prior to this a few modifications were made. Modifications: The time allowed for recovery was not between 2 to 4 minutes as planned, instead it was 5 minutes. Instead of using the stairs to carry out the experiment, we used a bench. A metronome was not used during the experiment. Results: * It was hard to always get the resting heart rate before each exercise and so instead we waited until the resting heart rate was within 5 beats/minute of the original one. * The resting heart rate was measured for 30 seconds, three times before the exercise whereas the finishing heart rate was measured once for 15 seconds after the exercise. These were made up to beats/minute as shown in the table of results.
