The Yo-Yo test is a fitness test designed for team sports like soccer, basketball, and rugby. It measures your ability to repeatedly perform high-intensity running with short recovery breaks in between, mimicking the stop-and-go demands of an actual game. Developed by Danish sports scientist Jens Bangsbo and colleagues during the 1990s, it has become one of the most widely used field tests in professional and amateur sports worldwide.
How the Test Works
The basic setup requires a flat surface at least 30 meters long, some cones, and an audio recording that controls the pace. Three lines of cones mark out the course: two lines 20 meters apart for the main shuttle, and a third line 5 meters behind the start to create a recovery zone.
You begin at the middle line. When the audio beep sounds, you run 20 meters to the far line, then turn and run 20 meters back to the start. That counts as one shuttle. After each shuttle, you get 10 seconds of active recovery, during which you jog or walk into the 5-meter recovery zone behind you and back to the start line. Then the next beep sounds and you go again.
The speed starts relatively slow but increases at set intervals. The audio recording controls everything: each beep tells you when to start running, and you need to reach each line before the next beep sounds. As the levels progress, the time allowed for each 20-meter shuttle gets shorter, forcing you to run faster. The first shuttle pace works out to about 14.5 seconds for 20 meters, which is already faster than the opening stages of the standard beep test.
How You’re Scored
Your score is the total distance covered before you can no longer keep up with the beeps. If you fail to reach the far cone and return to the start line before the beep, you receive a warning. If you fail a second consecutive time, you’re eliminated from the test. This two-strike rule means a single slow shuttle won’t end your test, but two in a row will.
Distances are recorded in meters, and each level and shuttle number corresponds to a specific cumulative distance. Coaches and sports scientists use these scores to track fitness changes over a season, compare players within a squad, and estimate aerobic capacity. A formula developed by Bangsbo converts your distance into an estimated VO2 max (a measure of how efficiently your body uses oxygen during exercise): VO2 max = distance in meters × 0.0084 + 36.4.
Test Versions
There are several variations, each designed for a different purpose:
- Yo-Yo Intermittent Recovery Test Level 1 (IR1): The most commonly used version. It starts at a moderate pace and includes the 10-second recovery period between shuttles. It’s suitable for recreational athletes, youth players, and sub-elite competitors, and it primarily measures your capacity to recover from repeated bouts of exercise.
- Yo-Yo Intermittent Recovery Test Level 2 (IR2): Starts at a faster pace than Level 1 and is aimed at well-trained and elite athletes. It places a greater emphasis on your ability to perform intense anaerobic work repeatedly.
- Yo-Yo Intermittent Endurance Test: Uses a 5-second recovery period instead of 10 seconds, making it more continuous in nature. This version is closer to a traditional endurance test and is less commonly used than the recovery versions.
How It Differs From the Beep Test
The Yo-Yo test is often confused with the beep test (also called the multi-stage fitness test or pacer test), and the two do look similar at first glance. Both involve running shuttles at increasing speeds dictated by audio beeps. The key difference is the recovery period. The beep test is continuous: you run back and forth without stopping until you can’t keep up. The Yo-Yo test builds in that 10-second active recovery after every shuttle.
That recovery period is what makes the Yo-Yo test more relevant for team sports. Soccer players, for example, change activity roughly every 3 to 5 seconds during a match, alternating between sprints, jogs, and brief pauses. A continuous running test measures pure aerobic endurance, but it doesn’t capture your ability to recover quickly and go again, which is what actually matters on the pitch. This is why the Yo-Yo test became popular in the first place: traditional VO2 max testing was seen as lacking specificity and practicality for intermittent sports.
What Professional Scores Look Like
To put scores in context, a study tracking an entire professional football league over a full season found that players averaged 847 meters on the IR2 at preseason. That rose to 975 meters by the start of the competitive season and peaked at about 1,034 meters at mid-season. Roughly half of all players hit their best scores around the middle of the season.
Team quality correlated with fitness. Top-ranked and mid-table teams averaged between 1,094 and 1,121 meters at peak, while bottom-table teams averaged 992 meters. Regular starters also consistently outperformed squad players who saw less match time, scoring about 16% higher throughout the season. These numbers reflect the IR2 version, so they represent well-trained professionals. Recreational or youth athletes would typically score considerably lower.
What You Need to Run One
The test is deliberately low-tech, which is a big part of its appeal. You need a flat, non-slip surface with at least 30 meters of length, marking cones to set up the three lines (two at 20 meters apart, one at 5 meters for the recovery zone), and the official audio file played through a speaker loud enough for all participants to hear clearly. The audio files are available as MP3s or CDs in versions specific to each test type and level. Speaker volume matters more than you might expect: if runners at the far end can’t hear the beeps, timing breaks down.
Multiple athletes can run the test simultaneously, each using their own lane, which makes it practical for entire teams to complete in a single session. One or two people should act as timekeepers to track each runner’s shuttle count and issue warnings when someone fails to make the line in time.
