Yo-Yo Endurance Test

The Yo-Yo Endurance Test (continuous) is a variation of the beep test, part of the yo-yo test series developed by the Danish soccer physiologist Jens Bangsbo. There are two versions of this test: Level 1 & 2 (a beginners and advanced level).

The level one test is effectively the same as the standard beep test. The Level 2 test starts at a higher running speed and has different increments in speed (see Yo-Yo Endurance Test Levels). There is also an intermittent version of the Yo-Yo test, which incorporates a recovery period after each 40m (2x20m) run.

  • purpose: The test evaluates an individual's aerobic endurance fitness.

  • procedure: Use cones to mark out two lines 20 meters apart as per the diagram. The subjects start with their foot behind one of the lines, and begin running when instructed. They continue running between the two lines, turning when signaled by the recorded beeps. After each minute or so, the pace gets quicker. If the line is not reached in time the subject must run to the line turn and try to catch up with the pace within 2 more ‘beeps’. The test is stopped if the subject fails to catch up with the pace within the two ends.
  • variations: There are two versions of this test: Level 1 & 2. The level one test is effectively the same as the standard beep test. The Level 2 test starts at a higher running speed and has different increments in speed. See Yo-Yo Endurance Test levels. See also about Beep Test variations.
  • scoring: The athlete's score is the total distance covered before they were unable to keep up with the recording. The Yo-Yo intermittent test usually takes between 6-20 minutes for level 1 and between 2-10 minutes for level 2. See some Yo Yo Test Results.
  • target population: This test is suitable for sports teams and school groups, but not for populations in which a maximal exercise test would be contraindicated. It is commonly performed by soccer players.
  • reliability: Reliability would depend on how strictly the test is run, and the previous practice allowed for the subjects.
  • advantages: Large groups can perform this test all at once for minimal costs.
  • disadvantages: Practice and motivation levels can influence the score attained, and the scoring of when a person is out of the test can be subjective. As the test is usually conducted outside, the environmental conditions can also affect the results. The test cd must be purchased.
  • other considerations: This test is a maximal test, which requires a reasonable level of fitness. It is not recommended for recreational athletes or people with health problems, injuries or low fitness levels. You may not have power where you want to conduct this test. If so, you need to ensure that the batteries of the audio player are fully charged.
  • comments: This test was developed by the Danish soccer physiologist Jens Bangsbo and his colleagues.

This study found that the Yo-Yo Intermittent Recovery Test "had a high reproducibility and sensitivity, allowing for detailed analysis of the physical capacity of athletes in intermittent sports. Specifically, the Yo-Yo intermittent recovery test was a valid measure of fitness performance in soccer. During the test, the aerobic loading approached maximal values, and the anaerobic energy system was highly taxed. Additionally, the study suggests that fatigue during intense intermittent short-term exercise was unrelated to muscle CP, lactate, pH, and glycogen."

This study concluded that the "Yo-Yo IR2 test is reproducible and can be used to evaluate an athlete's ability to perform intense intermittent exercise with a high rate of aerobic and anaerobic energy turnover. Specifically, the Yo-Yo IR2 test was shown to be a sensitive tool to differentiate between intermittent exercise performance of soccer players in different seasonal periods and at different competitive levels and playing positions."

What is Yo-Yo endurance test? India captain Virat Kohli has mastered it, Yuvraj a failure

The Yo-Yo endurance test will surely help India in becoming a fitter side in world cricket.

 
 
 
 

Besides batting and bowling skills, one of the most-important pre-requisites of modern-day cricketers is fitness. With the ever growing demands of world cricket, and the rise of T20 cricket for the last couple of years, there is very little room for unfit players, and teams are taking such things very seriously.

Only a few days ago, chief selector of India, MSK Prasad had also stressed on the importance of fitness for the Indian players.

It was also revealed recently that Yuvraj Singh was left out of the ODI squad for Sri Lanka as he failed his fitness test, known as 'Yo-Yo' endurance test. The process is said to be software-based. 

What does this 'Yo-Yo' endurance test exactly mean?

It does not involve any cricket balls or bat, but it is a sheer test of a player's fitness, where an object, primarily cones, are placed on the field, consisting of two lines normally 20m apart. The cricketer has to run along the two set lines as soon as he is instructed. He will have to return after he hears a beep.

That may not sound too tough in the initial phase, but that is just the start of the endurance test as the pace picks up after a few minutes, making it more difficult. But, there is no holding back for the player, who has to get in terms with it, and double his pace too as the test moves ahead.

In case, the player fails to catch up with the pace of the test, he needs to somehow gather extra pace and catch within the next two beeps. If the players fails to catch up with pace in the next two ends, the test also comes to an end, reported Press Trust of India.

It is this test, which is being used by the India cricket team. India captain Virat Kohli seems to be the best in this field as well, as his Yo-Yo score reads 21 while the pass mark is 19.5 and above. Yuvraj was way below the mark, with Yo-Yo score of 16 only.

Surely, this has to be a positive step for India cricket. Gone are the days when fitness was never an issue for a player if one had the skills to bat and bowl. Such fitness levels will only help in India becoming a strong fielding side with agile and superbly fit players in the team.

This is ok as long as not implemented for test selection. Test cricket is game of technique, skill, patience, determination and perseverance, not fitness. If tomorrow Ashwin and Pujara fail the test will you drop them from the test team? Just like ground fielding, dives and fielding stunts work in LOIs but catching is more important in test cricket, we need to use such technology judiciously.

Passing these tests is a not big deal. Average players should be able to do it easily. Pujara and Ashwin won't fail these tests as of now. They are not asking everyone to be above 21 level. If they had then we can say that technique, skill and patience is more important. One doesn't need to be superman to pass these tests.

 

Failing these tests is certainly big issue.

I am talking only about test cricket ,do you think guys like Herath, Ranatunga, Boon, Gatting, Inzi, Warne would have passed such tests? Weren't they good enough in spite of their physical shortcomings? Tomorrow if we produce a player who is better than SRT with the bat and Ashwin with the ball, but with physical fitness of a sloth bear? Suppose such a player gets a yoyo score of 16, should we choose a Rayudu or Manish Pandey over him because they have better yoyo score? Test cricket is not a physically intensive game like boxing, tennis or basketball, we shouldn't give too much importance to these tests. Yoyo is a fad, tomorrow another fad will come and everyone will go gaga over the new toy.

 

I think the focus is on fielding and running between the wickets with these sort of tests. A physically superfit guy like Kohli may get a yoyo score of 21 but bottom line is that doesn't even help his catching, he drops 3 of them for every successful attempt. A fat unfit guy like Boon/Gatting may have tubs for hands, in fact both Boon and Gatting were ATG catchers, better than what Kohli can aspire to be in his wildest dream. Even Inzi and Warne were better catchers than Kohli. It is also perfectly possible for the fat guys to score daddy 100s and be excellent judges of running between the wickets. You don't need superhuman fitness in test cricket. SMG pointed this out beautifully in the 2004 Chennai test where motu Sehwag batted a whole day to score a 155 while athletic ripped Kaif got all cramped out after a session of batting.

The world has changed so are the requirements for modern pro sports. If warne and tunga were probably they could have achieved more. Their is no excuse for being fat and lazy for pro.
