KYNEX testing protocol
Yo-Yo Intermittent Recovery Test Level 1
Use the same measured course, IR1 audio, recovery zone, and scoring convention each time so one result can be compared responsibly with the next.
Equipment
- A measured 20 m shuttle lane with clear turn lines.
- A 5 m active-recovery zone behind the start line.
- The correct Yo-Yo IR1 audio played through an audible speaker.
- Cones and a score sheet or observer record.
Set up
- Confirm the audio is the IR1 protocol before beginning.
- Measure the 20 m lane and 5 m recovery zone rather than estimating them.
- Use a flat, non-slip surface and keep the lane clear.
- Complete an appropriate warm-up before the first shuttle.
Run the test
- Run 20 m out and 20 m back in time with the audio signals.
- Use the recovery period and recovery zone exactly as directed by the audio.
- Continue through increasing speeds until the protocol termination rule is reached.
- Use an observer when possible to track warnings and the final completed shuttle.
Record the result
- Record the last fully completed level and shuttle.
- Keep the audio version, surface, footwear, and test date with the result.
- Mark athlete-entered results provisional unless the test was supervised under an approved protocol.
- Do not compare scores collected with different Yo-Yo protocol variants as if they were equivalent.
Testing and safety note
This page standardizes recording; it does not replace the official IR1 audio instructions or qualified supervision. Stop if the athlete feels unwell. A Yo-Yo result is not medical clearance, injury prediction, or a selection guarantee.
