Recovery of Pulse Rate After Exercise
Background and Information
Background and Information The pulse is the blood surging through the arteries each time that the heart pumps. A person's resting pulse rate is the pulse rate when a person is sitting still without moving. You can measure your pulse rate by placing pressure on your wrist. Some people find it easier to measure their pulse on their neck. There are many locations where we can feel the blood surging through our arteries. Measure your resting pulse rate wherever it is convenient.

My
Resting Pulse Rate: __________bpm (beats per minute)
|
During exercise the pulse increases as the heart beats faster. People in good cardiovascular health have a slower pulse because their larger and stronger hearts can pump the blood in fewer beats. Their pulse returns to normal faster after exercise. This laboratory will measure pulse rates to see which subject is in the best shape. In this lab you will measure pulse rate in relation to time to determine the recovery rate of the subject's pulse. The subject will run up and down the stairs as quickly as possible until his/her pulse rate is much faster than normal. You will then measure the subject's pulse rate using a computer or a stopwatch if the computer is not functioning correctly. The purpose of this lab is to determine is some people's pulse rates will return to normal faster than others. After you have turned on your computer, double click on the "Heart Ra...Monitor" icon in the applications folder. You should have a graph "untitled". Place the ear clip on the subject's earlobe. Click on start to check if everything is working. Determine the subject's resting pulse rate. Immediately after returning from exercise, the subject should sit down and place the clip on the ear. Click on the start. The subject should avoid moving his/her head. After the pulse has returned to normal for a few readings, click on stop. Go up to Windows and open Table. The table should look like this:

Fill in the data in the observation section of your lab report by finding the closet reading for the time listed in the table. Now click on Windows again and open Graph. Copy the graph on your computer screen in the Estimated Graph section of your lab report. Go to File and quit program. If you are a member of the last integrated science class of the day, unplug the heart rate monitor and ULI board. Return them to the boxes.
With the data that you have recorded in the observation section, make a line graph for the analyzed data section of you lab report. The estimated and actual graphs of recover rates should appear similar if you have graphed correctly. On the same graph at least 2 other students' recovery rates.
