When we increase the steps during exercise, what happens to our pulse rate?
Pulse Rate When your heart beats, the pressure of blood being squeezed into arteries causes them to bulge slightly. This pulse can be felt at certain places, for example, on the thumb side of your wrist or on the side of your Adam s apple. This pulse can be felt at certain places, When your heart beats, the pressure of blood being squeezed into arteries causes them to bulge slightly. Pulse rate is the number of times your heart beats in a minute Pulse rate can be measured using your finger and a stopwatch.
Pulse When your hear C:\CACHE\Temporary Internet Files\Content.IE5\XLREI2KB\MC900434722[1].png Watch the video clip. Listen carefully as you are going to have to answer questions on it., the pressure of blood being squeezed into is pulse can be felt at certain places, for example, on the thumb side of your wrist or on the side of your Adam s apple. Copy the following table. Cab you remember the two places it told you where you can feel your pulse?
Recording pulse rate When pulse rate was taken seconds) At rest Immediately after exercise 1 minute after exercise 2 minutes after exercise Pulse rate (in 15 Pulse rate (beats per minute) 3 minutes after exercise 4 minutes after exercise 5 minutes after exercise
Measuring pulse rate. Work with a partner. The person with the stopwatch should shout start and start the stopwatch. The other person should start counting how many times they feel a beat or pulse. When the stopwatch shows 15 seconds the person timing should shout stop and the person should stop counting. Write your pulse rate in your table. How do you find out what it is in a minute? Do this and record it in your table too. Swap.
During exercise your pulse rate would have increased. How much did it increase by? Why? The fitter you are, the less your pulse rate will increase during exercise. It will also return to the normal resting value faster if you are fit.

You should now carry out a google search to find out what the normal pulse rate range is. We hope you enjoyed your task and we look forward to meeting you in August.
