Investigating Pulse Rate

Extracts from this document...


Investigating Pulse Rate Plan: I am doing an experiment to measure pulse rates. I am going to run at a prolonged pace for 30,60,90 and 120 seconds. I will then take a reading of my pulse. I will repeat my experiment to give a more accurate set of results. I will be taking results on myself and two other people, so that I can compare my level of fitness and heart rate to theirs. Fair Test: To make sure that my experiment is a fair one I need to keep some factors the same each time. I need to make sure that I run for the specified amount of time, i.e. ...read more.


I also need to make sure that I take my pulse for the same amount of time, every time I take it. I am going to measure my pulse for 60 seconds, instead of 15 seconds and then multiplying the answer by 4. Prediction: My prediction is the obvious one that as I start to exercise harder, my pulse rate will rise. This is because as you begin to exercise, your muscles demand more oxygen. Your heart has to work harder and pump faster to get this oxygen to the muscles. The level of your pulse rate also depends on your level of fitness. If you were an ultra-fit marathon runner, you would have a low heart rate. ...read more.


= Repeat = First Trial This graph shows my average pulse rates. = Averages In my results it shows that the longer you exercise for the higher your pulse rate gets. This in keeps with my prediction. The pulse rate gets higher because as I/we exercise, our muscles become oxygen starved and demand more oxygen. Our heart has to beat harder and faster to pump the oxygen around. As you see on the graph overleaf, Jack has a lower pulse rate throughout. This may be because he does more exercise than me or it may be because he is of a different build than me. Luke has a higher pulse rate than me. Similarly, he might do less exercise than me or be of a different build. Evaluating: ...read more.
