The speed remains constant for the entire level. Starting at level one requires you to run at a pace of approximately 8.0km/hr increasing to 9.0km/hr for level 2 then by 0.5km/hr with each level thereafter. The test is structured into 21 levels and each level is broken up into a determined number of shuttles and each level lasts approximately 62 seconds (see beep test levels details below). It is also used for determining eligibility to gain entrance or employment by some sporting clubs and organisations. The beep test which is also known as the multi-stage fitness test, bleep test, pacer test and 20-metre shuttle run is commonly used by sporting clubs and organisations to test a person’s VO2 maximum.
