The Yo-Yo fitness Test
The Yo-Yo determines the maximum aerobic endurance of a player. The test is derived from the Shuttle Run Test.
With this test the participants run back and forth across the gym or training pitch between two lines/markers set twenty meters apart until the players fails to reach the mark at the 'beep' on three consecutive laps or shuttles. After each inidvidual shuttle the players has an active recovery period of 10 seconds. For this, the player jogs up-and-down two cones set 5 meters apart.
The
test is usually performed indoor and the speed of the participants is
determined by the interval between the audio beeps played on a CD player, cassette or laptop.
Background information on the YoYo test
The starting speed is 10 km/h and each minute the speed is increased by decreasing the interval between the beeps, see the table below for ‘beep’ interval times for each one minute stage.

Players should pivot on the line at the moment of the beep (not quicker or slower). The test result is expressed in stages, you can score between 1/2 or 1 stage.

Practicalities
Timing is critical so it is important for the CD/MP3 or older audio cassette plays at the correct speed. We have found that CD players can be affected by pitch controls (set these at neural or off), MP3 playback speed can be affected by mismatch on CODEC sample rates.
Check the playback with the 1 min. test period at the start of the tape. If not possible to adjust for errors in playback speed you will have to work with the shuttle length using this table:
