"The test is a standard test battery with progressively increasing speeds. After every 40-m run (2x20 m), active rest is performed by walking or jogging at a distance of 10 m (2x5 m). for 10 seconds. Participants are trying to adjust their speed according to incoming audio signals.The test is terminated when the participants can not reach the signal twice. The test ends in 10-20 minutes depending on the level of participants.~Reference Bangsbo, J., Iaia, F. M., \& Krustrup, P. (2008). The Yo-Yo intermittent recovery test.
