The Yo-Yo Intermittent Test is a test of the ability to undertake intermittent exercise - there are two variations, below is the description of the recovery version and there is also the endurance version.

The participants in this test have a short 10 seconds active break after each 40m (2 x 20 m runs), with the speed increasing at intervals (see a full description of the Yo-Yo Intermittent Test). There are two versions of the Yo-Yo Intermittent Recovery Test: the Level or Stage 1 test starts at 10 km/hr and the Level or Stage 2 test starts at 13 km/hr. The Yo-Yo Intermittent Endurance Test has different speeds and only 5 second recovery between each 40m bouts. The Yo-Yo test recording can be performed using the Team BeepTest software.

The results normally report the speed level plus number of shuttles.

Yo-Yo Intermittent Recovery Test Level 1 (YYIRTL1)

Below are the levels, speeds and accumulated distances for the Yo-Yo Intermittent Recovery Test 1. The results can be given as the total distance covered, level number achieved, or speed level (such as 16.3, which would mean level 30 or 1200 meters). The results normally report the speed level plus number of shuttles.

Marcello Iaia and Peter Krustrup, Sports Med 2008; 38 (1): 37-51. In the paper by Castagna et al. (2006), the speed listed for stage 2 was 12 km/hr, all other speeds were the same as above.

Yo-Yo Intermittent Recovery Test Level 2 (YYIRTL2)

Below are the levels, speeds and accumulated distances for the Yo-Yo Intermittent Recovery Test 2 of the Yo-Yo Intermittent Test. The results can be given as the total distance covered, level number achieved, or speed level (such as 22.3, which would mean level 30 or 1200 meters).
