Yo-Yo Intermittent Recovery Test: Level 1 (Audio)

The Yo-Yo intermittent test is aimed at estimating performance in stop-and-go sports like Rugby, football (soccer), cricket, basketball and Field Hockey. Like many other fitness tests, it involves running at ever-increasing speeds, to exhaustion. However, a crucial difference is that the Yo-Yo Intermittent test has periodic rest intervals, thus simulating the nature of exertion in stop-and-go sports.

There are two versions of each Yo-Yo Intermittent Test, a beginners Level 1 and advanced level 2. This video is used for the aforementioned, Level 1.


The Test Audio begins at 01:45 and the first circuit at 1:54.

Equipment required: A Flat, non-slip surface, marking cones, measuring tape and this video/audio.

Test Procedure: The setup for all 4 versions of this test are identical. Prior to the test commencing, runners line up at the 5 m marker, facing the 25 m marker. Following a countdown, a double beep signals the start.

1) Runners commence running towards the 25 m marker
2) At or before the following beep, runners must reach the 25 m marker. Touching with a single foot is acceptable.
3) At or after, but not before, the same beep, runners commence running back to the 5 m marker.
4) At or before the next beep, runners must reach back to the 5 m marker
5) The rest period now commences 10 seconds in the Recovery tests, 5 seconds in the Endurance tests. Runners stroll to the 0 m marker, then return to the 5 m marker.
6) A beep indicates the end of the rest period and the start of the next circuit (back to Step 1)

After a predetermined number of circuits at a speed level (which varies with each version of the test), the speed level changes. This is signalled, usually, by a double beep or, possibly, a voice cue. The required speed at the new speed level will be faster.

Test Scoring: A runner who fails to reach the relevant marker in time is cautioned; if they want to continue, they must touch the marker before turning back. Two consecutive failures terminate their attempt. Their most recent successful circuit is marked as their score.

Scoring is usually done using "Speed Level. Circuits" terminology; for example, 15.2, which means "completed 2 circuits at level 15". Alternatively, scores may be recorded as distance; for example, 840 m. The two methods correlate exactly, meaning that given one, it is possible to determine the other (see the tables below).

Note that scores in one version of the test do not correlate with scores in other versions. That is, a score of 15.2 in Yo-Yo IR1 is not the same as 15.2 in Yo-Yo IR2.
