Effects of exercise on pulse rate
I can describe how to measure a person’s pulse rate before and after exercise and calculate their recovery time.
These resources will be removed by end of Summer Term 2025.

Lesson details
Key learning points
- How to measure pulse rate.
- How to control the type and duration of exercise to be undertaken by a test subject.
- Record resting pulse rate before exercise and take repeated measurements of pulse rate after exercise.
- The recovery time is the time it takes for the pulse rate to return to the resting rate after exercise.
Keywords
Pulse rate - The number of heart beats (pulses) per minute.
Resting pulse rate - The number of times your heart beats when at rest.
Recovery time - The time it takes for the heart rate to return to the resting rate after exercise.
Common misconception
Pupils may think that people are either healthy or unhealthy.
Health is a range from good to ill. Fitness is one indicator of general health.
If the student is not able to find their pulse on their wrist, they could use their neck instead. If they are still unable to find it they could count the number of breaths they taken in a minute. A line graph should ideally have 5 points - LC3 is just for plotting demonstration.
