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.

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.

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.
