Our conclusions from the pulse rate activity

You can find our full conclusion in our class book, but after analysing the data and having a long discussion, we decided:

  • Your heart rate is lower when you are resting because your muscles do not need very much oxygenated blood
  • As you begin exercise, your body and muscles are working harder so you need more oxygenated blood. Because of this, your heart begins to pump faster
  • As you exercise even more vigorously, your body is screaming for oxygenated blood, so your heart has to work EVEN faster
  • When you relax and rest, your heart rate slows down again as your body is no longer in such a great need of oxygenated blood

Here are two graphs showing Anya’s and Sammy’s results (the end spike is where we decided to do a final test: how does jogging for 30 seconds effect the heart rate?):
