Conversion of the YYIR2 Results to VO2max
The Yo-Yo Intermittent Recovery Test Level 2 (YYIR2) is a fitness test for highly trained team sport athletes (though the Yo-Yo IR Level 1 is more commonly used). Participants run out and back on a 20-meter course, followed by a 10-second rest period between each run. The required running speed increases until they are unable to continue. Results on this test correlate with aerobic fitness scores, and can be converted to a VO2max score. You can use our calculator to work out the VO2max, or use this conversion chart, based on the same formula (Bangsbo et al. 2008), which is:
VO2max (ml/min/kg) = distance run × 0.0136 + 45.3
