Whether you call it the Beep, Bleep, or Yo-Yo Test all the names are all essentially synonymous. Jens Bangsbo, a Danish soccer physiologist, developed the beep test in the early 90’s. It is wildly popular with soccer teams worldwide, but has applications for all sports of intermittent nature.
Well in this case I am referring to one specific variation of the beep test: the Yo-Yo Intermittent Recovery Test (Yo-Yo IR1 or 2). This assessment is fantastic for team sports of an intermittent nature (meaning there’s a lot of stop-and-go). I use it with my basketball, lacrosse, and soccer teams. It would also be appropriate for rugby.
***Disclaimer: This is a MAXIMAL effort test and should only be conducted with competitive athletes, not recreational athletes. There is a high level of fitness needed to successfully complete testing.
Why this test is so great:
- It is SUPER easy to implement in a team environment! You don’t need any special equipment; just some cones, measuring tape, whistle, and an app that plays the test version you want (the one I use cost about $3).
- It allows a coach to know an athlete’s VO2max for comparison and progress tracking purposes without having to use any fancy-schmancy equipment.
- The Intermittent Beep Test is a fairly sport-specific test for the team sports I listed above. It accounts for the frequent sprints, cuts, and walking associated with such sports and allows us coaches to apply a structure for analysis. This test goes light-years beyond simply running the mile in terms of the relevance of information that can be extracted.
Setup & Protocol:
- Create lanes for each athlete to run within – a lane is comprised of 3 cones. From where you place cone 1, measure out 5 meters and drop the second cone, from cone 2, measure out 20 meters and drop the third cone. Repeat this process for the number of lanes you need.
- Be certain to go over the rules of the Beep Test thoroughly with the athletes ahead of time. The speed increases as the test progresses and sometimes that’s hard for them to grasp. I usually let the group do a few passes as practice to remember what the test feels and sounds like.
- Start the test! If you are using this with a large team, you’ll want to divide the group in half and run it in two flights. This way, the athletes can partner up and the non-running athlete can count the total number of sprints for the runner.
- Two “misses” end the test. Record the total number of sprints.
***The purpose of reviewing test structure is simply to give you an idea of how the Beep Test is conducted. Consult formal instructions that come with the recording/app for more detailed information.
Once you’ve recorded the results, now you want to know what it means! Simply plug your results into one of these two formulas to get the VO2max estimation:
Yo-Yo IR1 test:VO2max (mL/min/kg) = IR1 distance (m) × 0.0084 + 36.4
Yo-Yo IR2 test: VO2max (mL/min/kg) = IR2 distance (m) × 0.0136 + 45.3
Now that you know where your athletes’ VO2max scores fall, you can begin to track and compare across other sporting platforms and look vertically within your sport at different levels to see where your athletes fall.
