The Effect of Exercise on Pulse Rate

The Effect of Exercise on Pulse Rate

In this experiment I am trying to find out how exercise affects my

pulse rate. I will do this by exercising then measuring my pulse rate.

In this experiment I will use 2 pieces of equipment, a stopwatch and

calculator. I will use the stopwatch to time how long I exercise for

and the measure my pulse rate and I will use the calculator to work

out my pulse rate.

I will first exercise for 15 seconds then measure my pulse rate for 15

seconds then rest for 2 minutes then repeat the process. I will do

this 3 times then increase the amount of time I exercise for to 30

seconds and do the same but exercise for 30 seconds. I will increase

the amount of time I exercise for by 15 starting from 30 then,

45,60,75 and then 90 seconds. I will make sure results are reliable by

repeating them if they are slightly unreliable.

I predict that as the amount of time I exercise for increases so will

my pulse rate.

To make sure the experiment was safe I moved away all the chairs,

tables etc around the area I was exercising in so I would bump into

anything. Also I made sure I made sure the clothing I was wearing was

suitable to the exercise I was doing.
