Its is important to note that the running speeds at the start of the test are very slow. On level 1, you will have nine seconds in which to run each 20m shuttle.
You should always place one foot either on or behind the 20m mark at the end of each shuttle. If you arrive at the end of the shuttle before the bleep sounds, you should turn around and wait for the bleep, then resume running and adjust your speed.
You must run for as long as possible, until you can no longer keep up with the speed set by the disc, at which point you should voluntarily withdraw from the test. In some cases the PTI conducting the test may need to withdraw you when it becomes apparent that you are dropping behind the required pace and are unable to meet the marker on 3 consecutive shuttles.
Observers will make notes of the level and number of shuttles into the level, at which you withdraw, from the test. Using the Table of Predicted Maximum Oxygen Uptake Values, an estimate of maximum oxygen uptake can be obtained and scored.
