Yo-Yo Intermittent Recovery Test Levels

The Yo-Yo Intermittent Test is a test of the ability to undertake intermittent exercise. 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 Test: the Level or Stage 1 test starts at 10 km/hr and the Level or Stage 2 test starts at 13 km/hr. See also the levels for the Yo-Yo Intermittent Endurance Test, which has different speeds and a 5 second recovery between bouts. A Yo-Yo test recording can be replicated using the Team BeepTest software.
