Principles of the Yo-Yo tests Print
Yo-yo testThe Yo-Yo tests contain running activities that are relevant for many sports. The tests can be performed by both men and women of all ages. The tests can also be used for assessing the physical capacity of young athletes.

The basics of the tests are simple. For the Yo-Yo endurance test, two markers are positioned at a distance of 20 meters. The CD is placed in a CD player and the test can be performed. The individual begins to run forward 20 meters at the time of a signal given on the CD. The running speed should be adjusted, so that he or she reaches the 20 meters marker exactly at the time of the next signal. A turn is made at the 20 meters marker and the individual runs back to the first marker, which has to be reached at the time of the next signal. If an individual runs the distance too quickly he or she must wait at the marker until the next signal.

The principles of the Yo-Yo intermittent endurance test and the Yo-Yo intermittent recovery test are similar to the Yo-Yo endurance test, except in the intermittent tests the participants have a short active break (5 and 10 seconds for the endurance and recovery test, respectively).

I have seen the formula to evaluate Vo2max from the Yo-Yo intermittent RECOVERY test, but is that the same formula as the formula for the Yo-Yo intermittent ENDURANCE test level 2??

Hi there. I have run the Yoyo Intermittent Endurance Level 1 and am desperately looking for some result data that will equate to the standard beep. Also what the formula is for VO2max on the YYIET L1. Initially I didnt realise there were 4 yoyo tests with obviously different results and statistical analysis Can anyone help please?

Does the IR2 test is valid for women (VO2max = 35-45 ml.min.kg ). Should we start at a lower speed?

Yo-Yo IR1 test: VO2max (mL/min/kg) = IR1 distance (m) X 0.0084 + 36.4
Yo-Yo IR2 test: VO2max (mL/min/kg) = IR2 distance (m) X 0.0136 + 45.3

i have a question. 2 players of mine completed level 41, and from the calculation using the formula given, their VO2max is 50.2mL/min/kg.

how accurate is this? because one player weighs 50.2kg, while the other weighs 56.6kg.

i would think the VO2max for the first player should be higher than the second player, due to his weight eventhough they covered the same distance.

any comments....?

I really don't know why anybody need VO2max. First, you will get 53ml/kg/min for test results between 1450 and 2600m in YO YO IR1 test. Second, YO YO IR test is not a test for evaluation of VO2max. And finally, VO2max is not good parameter for evaluation of soccer players!!!
