Yo-Yo Intermittent Tests

The Yo-Yo Intermittent Tests are a valuable tool for assessing an individual’s ability to perform intervals over an extended period. These tests are particularly relevant for athletes involved in sports like tennis, team handball, basketball, soccer, and similar activities. In this article, we will explore the different aspects of the Yo-Yo Intermittent Tests, including their purpose, equipment requirements, testing procedures, variations, scoring, target population, reliability, advantages, and disadvantages.


The primary purpose of the Yo-Yo Intermittent Tests is to evaluate an individual’s capacity to repeatedly perform intervals over a prolonged period. These tests are specifically designed for athletes participating in sports that involve intermittent bursts of activity. By measuring an athlete’s performance in these tests, coaches and trainers can assess their aerobic endurance and overall fitness levels.

Equipment Requirements

To conduct the Yo-Yo Intermittent Tests, you will need a flat, non-slip surface, marking cones, a measuring tape, a pre-recorded audio CD or MP3, a CD player, and recording sheets. It is crucial to ensure that you have all the necessary equipment prepared before conducting the tests to ensure accurate results.

Testing Procedures

The Yo-Yo Intermittent Tests involve running specific distances and incorporating short active breaks. Participants start on or behind the middle line and run 20 meters when prompted by the audio CD or MP3. They then turn and return to the starting point upon hearing the recorded beep. During each 20-meter shuttle, there is an active recovery period of either 5 or 10 seconds, depending on the test variation. Participants must walk or jog around a cone and then return to the starting point within the allocated recovery time. If a participant fails to complete a successful shuttle within the given time, a warning is issued, and they may be removed from the test if they fail again.

There are two levels for each of the Yo-Yo Intermittent Tests: level 1 for beginners or lesser trained individuals, and level 2 for well-trained and elite athletes. The levels differ in terms of speed and difficulty, with level 2 starting at a faster pace. Both test variations have increasing speeds throughout the duration of the test. Coaches and trainers can choose the appropriate level based on the athletes’ fitness levels and training objectives.


The athlete’s score in the Yo-Yo Intermittent Tests is determined by the total distance covered before they are unable to keep up with the recording. The duration of the tests can vary, with level 1 typically taking between 6-20 minutes and level 2 lasting between 2-10 minutes. It is important to refer to the specific speeds and distances for more accurate scoring information.

Target Population

The Yo-Yo Intermittent Tests were initially developed for soccer players but are also suitable for athletes participating in similar sports that involve intermittent activity. The level 1 test is designed for recreational-level players, while the level 2 test is intended for elite soccer players. It is essential to note that these tests may not be suitable for individuals with health problems, injuries, or low fitness levels, as they are maximal tests requiring a reasonable level of fitness.


The reliability of the Yo-Yo Intermittent Tests depends on how strictly the test is administered and the participants’ previous practice. To ensure accurate and consistent results, it is important to follow standardized testing procedures and provide clear instructions to the participants. This will help minimize any potential variations in test outcomes.

Advantages and Disadvantages

One significant advantage of the Yo-Yo Intermittent Tests is that they can be performed with large groups simultaneously, making them cost-effective and time-efficient. However, it is important to consider that practice and motivation levels can influence the participants’ scores, and the scoring of when a person is out of the test can be subjective. Additionally, environmental conditions can also impact the results, especially when the tests are conducted outdoors. Another consideration is the requirement to purchase the test CD or MP3 for accurate timing and prompts.


Q: Who can benefit from the Yo-Yo Intermittent Tests?

A: The Yo-Yo Intermittent Tests are particularly beneficial for athletes involved in sports that require intermittent bursts of activity, such as soccer, tennis, team handball, basketball, and similar sports.

Q: Are the Yo-Yo Intermittent Tests suitable for recreational athletes?

A: The level 1 test is designed for recreational-level players, making it suitable for individuals at the beginner or intermediate fitness levels.

Q: Can the Yo-Yo Intermittent Tests be conducted indoors?

A: Yes, the tests can be conducted indoors as long as you have a suitable flat surface and enough space to mark out the required distances.

Q: Are there any formulae to estimate VO2max from the Yo-Yo Intermittent Test results?

A: Yes, for the Yo-Yo Intermittent Recovery Test (IR1) and Yo-Yo Intermittent Endurance Test (IR2), there are formulae published by Bangsbo et al. (2008) that allow for estimation of VO2max (ml/min/kg) based on the distances covered in the tests.

Q: What is the Yo-Yo Intermittent Test?

A: The Yo-Yo Intermittent Test is a series of shuttle runs that assess an individual’s ability to repeatedly perform intervals with short active breaks. It is widely used to evaluate aerobic endurance and fitness levels in athletes.


The Yo-Yo Intermittent Tests are a valuable tool for assessing an individual’s ability to perform intervals over a prolonged period. These tests provide essential insights into aerobic endurance and overall fitness levels, making them particularly relevant for athletes involved in sports that require intermittent bursts of activity. By conducting the tests accurately and following standardized procedures, coaches and trainers can gain valuable data to optimize training programs and track athletes’ progress over time.
