Treat this as a way to measure where you're at and where you should be. It is a way to collect information, it would be best if you could find someone to run this test with you. Maybe if you live close to a teammate or have a sibling or friend that will do the test with you. If you cant find anybody to run it will you then the next best thing is to have someone there to cheer you on and motivate you to keep running.
BE SURE TO WARMUP PROPERLYIt should last at least 8-10 mins minimum. Be sure to hit hip flexors, groin, hamstrings, and glutes really well (in addition to everything else). It should include some sprints and cutting. Excluding sprints doesn't "save up" anything towards yoyo - so don't fret.
