Optional test 1, Dynamic Yo-Yo: Procedure

  1. The cones must be set out as illustrated in the diagram below. It is important that the colours (i.e. red and yellow) are placed accurately and that the distance between the red and yellow cones is exactly 20 meters. Referees may start from the yellow or red cones. It is recommended that the test be run in groups comprising no more than two referees starting from each cone.
  2. Referees starting from a yellow cone should run to a red cone, turn and continue to the next yellow cone. Each run is interspersed by a recovery period.
  3. Referees starting from a red cone should run to a yellow cone, turn and continue to the next red cone. Each run is interspersed by a recovery period.
  4. The audio file will dictate the pace of the runs and the length of the each recovery period. Referees must keep pace with the audio file until they have reached the required recommended level.
  5. If a referee fails to place a foot on the ‘finish cone’ on time, they should receive a clear warning from the test leader. If a referee fails to arrive on time on a second occasion, they should be pulled from the test by the test leader.
