The Yo-Yo Intermittent Recovery Test Level 1 is one of six official versions of the yo-yo test, and is the most commonly used version. You might find it also referred to as theYYIR1, YYIRL1 or just the Yo-Yo test. There is also a Level 2 Yo-Yo Intermittent Recovery Test. The level 1 test was originally designed for recreational level athletes, while the level 2 test was designed for highly-trained athletes, though most sports tend to use the level one test for athletes of all fitness levels.

The Yo-Yo Intermittent Tests are similar to the Yo-Yo Endurance Test (a variation of the beep test), except in the intermittent tests the participants have a short active break (5 and 10 seconds for the intermittent endurance and intermittent recovery test, respectively).
- The Yo-Yo intermittent recovery test reflects the ability to perform high intensity running in soccer and it can determine seasonal changes in physical capacity of soccer players. However, it is unknown whether the test is sufficiently sensitive to detect the effect of different intermittent-exercise training regimes.

The Yo-Yo Intermittent Test is a fitness test designed to simulate the intermittent nature of certain sporting activities such as soccer and many other forms of football. It is like the beep test, except in the intermittent test the participants have a short active break of 10 seconds after each 2 shuttles.

You can read the general procedure for conducting the yo-yo test, below are details specific to this version.
Equipment Required: flat non-slip surface, marking cones, measuring tape, cd or mp3 player with good speakers, audio file or cd,recording sheets. See more details about the required Yo-Yo Test Equipment.
Course layout: Cones or tape is used to mark out three parallel lines, 5 and 20 meters apart, as shown in the diagram. Corel draw x9 free download.

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 10 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 1 Intermittent Recovery Test is 10.0km/hr, and increases to 12km/hr, 13km/hr, then increasing by 0.5 km/hr thereafter. For more details see the table of speeds and distances for the YYIR1.
Finishing the test: The participants must continue for as long as they can. 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.
You give a warning when the participant .. Pdr exe has stopped working.
- does not come to a complete stop before starting the next 40m run.
- starts the run before the audio signal.
- does not reach either line before the audio signal.
- turns at the 20m mark without touching or going over the line (therefore running short).
Scoring: the participant's score is the level or total distance covered in the last complete successful shuttle. Use this YYIR1 scoring sheet to keep track of athlete scores. See more about scoring.

Interpretation: You can use the YYIR1 table of norms to work out a fitness rating based on the score. There has been formula published for estimating VO2max (ml/min/kg) from the Yo-Yo IR1 results, you can use this YYIR1 calculator to work out VO2max and get a fitness rating.

In my most recent class, we were asked to write a small report explaining the concepts of reliability and validity as they relate to research methods, and subsequently to provide a sports science-related example of these two concepts. For me, this seemed like the perfect opportunity to profile my favourite soccer-specific fitness test, the Yo-Yo Intermittent Recovery Test. Chris isaak wicked game flac download. below is the short paper.
I’d love to hear your thoughts about this topic. Drop me a line here to get the conversation started.
The Yo-Yo Intermittent Recovery Test, created by researchers from the University of Copenhagen in Denmark, is a test of aerobic and anaerobic fitness that has been proven to be both reliable and valid. Comprising an incrementally faster 2 x 20 metre shuttle run, with a 10-second recovery period between each shuttle run, the Yo-Yo Intermittent Recovery Test has become one of the most popular on-field fitness tests in the sport of soccer, as well as in many other field sports.
The Yo-Yo test is reliable because it has been repeated thousands of times and has always been shown to have the same consistency and accuracy of measurement. A recent study by Krustrup et. al. (2006) reported that the Yo-Yo Intermittent Recovery Test was shown to have a very high test-retest consistency among Danish Professional soccer players, when the same players were tested multiple times. Whenever players get the same score (or close to the same score) on multiple trials of a test of physical fitness, the test can be said to be a reliable measurement tool.
The Yo-Yo Intermittent Recovery Test has also been shown to be a valid predictor of high intensity running ability (Krustrup et. al., 2007). High intensity running done by players (measured using time-motion analysis with global positioning satellite or GPS) was shown to be very well correlated to players’ performance on the Yo-Yo Test (Krustrup et. al., 2007). Because high intensity running is one of the key factors that differentiates between higher and lower levels of play in soccer (as well as in other field sports), the fact that the Yo-Yo Test is a valid predictor of high intensity running ability means that the Yo-Yo Test should also be a good predictor/differentiator between levels of play amongst soccer players.
