Amy designed an experiment to test how exercise affects adult men. The resting heart and respiratory rates were measured in fifty men between the ages of 25-55. Once a baseline was established, the men were asked to run on the treadmill for five minutes. The breathing rate and heart rate were recorded every thirty seconds.

However a standard method to dertmine how workload effects health is developed and is called Harvard step test.

The Harvard Step Test is a fitness test method devised to measure heart and respiratory fitness. It is done by giving some work load to a person for 5 minutes (normally) and then noting his heart rate afterwards in some intervals.
