Preparations: Make sure the participants are adequately prepared: well-rested, hydrated and fueled, and familiar with the test procedure and motivated to perform maximally. (see preparing for the yo-yo test for more details). Give clear and standardized instructions about the test and what is expected of them (see an example instruction), including the importance of keeping in time to the recording and completing the full 20m run.

Starting the Test: All participants should line up along the starting line. The athletes start with a foot behind the middle line (cone B), and begin running when instructed by the audio recording. The athlete turns when signaled by the recorded audio beep (at cone C), and returns to the starting point. The athlete must not start running early, must run the complete distance, and reach each line before or in time with the recording.

During the test: There is an active recovery period of 5 seconds between every 40 meters run, during which the subject must walk or jog to the next line (cone A) and return to the starting point. At regular intervals, the running speed will increase. The starting speed for the Level 2 Intermittent Endurance Test is 8.0km/hr, and increases by 1km/hr for the first few stages, then by 0.25 km/hr thereafter. For more details see the table of speeds and distances for the YYIE2. The participants must continue for as long as they can.

Finishing the test: Some of the athletes will choose to stop when they have reached their physical limit. For others, you will need to give a warning as they drop behind the required pace or make one of the errors listed below. On the second infraction you pull them out of the test.
