The beep fitness test should not be taken lightly. It is a maximal test, which means the participants are required to go as hard as they can for as long as they can (though they do not always do this).
This was highlighted recently when 27-year-old Welsh man Adam Rumming died while performing the bleep test as part of an army fitness test at the Sandhurst Academy where elite British Army officers are trained.
He is believed to have had an undiagnosed heart problem, which is often the case for sudden death during exercise in seemingly healthy young people.
If you are ever in charge of conducting fitness testing, particularly exhausting tests, you should exclude anyone with a fever or other risky medical condition, or even better get them to complete a PAR-Q (Physical Activity Readiness Questionnaire).
