Essay about The Effect Of Pulse Rate After Exercise
Average Beats per Minute
I took 3 reading of my beats per minute (BPM) to ensure I got an accurate result. I took 3 readings of 30 seconds and then multiplied them by 2 to get 3 readings of 60 seconds. I took my readings whilst sitting down and not talking having not done any physical activity (walking etc.) in the 10 minutes before I took my readings.

Decline of Pulse Rate after Exercise
Once I had taken my rest pulse rate, my classmates and I ran down 3 flights of stairs (76!), round the outside of the college building and then back to our classroom. I recorded my BPM every 60 seconds until I got to 300 seconds.

My graph showing the decline of pulse rate after exercise shows the change in the amount of oxygen our bodies need. Oxygen and glucose are the two main components of our basic energy needs. (livestrong.com, 2013)
When exercising, our muscles are moving much more vigorously and so our bodies have to work harder to get oxygen to our muscles, or else our muscles will stop working (Craig Freudenrich, 2014). The build-up of lactic acid in our muscles means that our muscles need more oxygen to break down the lactic acid. Lactic acid is the reason muscles feel tired after exercise.There are two processes involved in getting oxygen to the muscles; getting blood to…
