Exercise Heart Rate Lab
In this experiment, you will work in groups of three to see how exercise affects breathing and heart rates.
Choose one person to carry out the exercise, one person to measure and record heart rate, and the other to
measure and record breathing rate. Heart rate (beats per minute) is obtained by measuring the pulse (right)
for 15 seconds and then multiplying by four. Breathing rate (breaths per minute) is measured by counting
the number of breaths taken in 15 seconds and multiplying
PROCEDURE
Resting Measurements
Have the person carrying out the exercise sit down on a chair for five minutes. They should try not to
move. After five minutes of sitting, measure their heart rate and breathing rates. Record the resting data.
Exercising Measurements
Choose 1 exercise to perform. (Step ups onto a chair, jumping jacks, and running in place).
1. Begin the exercise for one minute. The teacher will help record the exercise time.
2. Take the heart rate and count breath rate. Record the data. You have 30 seconds to do this
before you begin again.
3. Complete the same exercise for another minute and record the heart rate again. We will
continue this for a total of 4 minutes of exercise.
4. The person exercising should stop just long enough for ht measurements to be taken.
There will be no more than 30 seconds of time to collect heart rate data and breathing rate
data.
Post Exercise Measurements
After the exercise period has finished, have the exerciser sit down in a chair. Take their
measurements 1 and 5 minutes after finishing the exercise. Record the results.

Graph your results. You will either need one graph with both sets of data or two separate
graphs.
