A yo-yo test involves a player shuttling between two cones that are set 20 metres apart on flat ground. He starts on a beep and needs to get to the cone at the other end before the second beep goes. He then turns back and returns to the starting cone before the third beep. That is one “shuttle”.
A player starts at speed level 5, which consists of one shuttle. The next speed level, which is 9, also consists of one shuttle. Speed level 11, the next step up, has two shuttles, while level 12 has three and level 13 four. There are eight shuttles per level from 14 upwards. Level 23 is the highest speed level in a yo-yo test, but no one has come close to getting there yet. Each shuttle covers a distance of 40 metres, and the accumulated distance is an aggregate of distance covered at every speed level.
The player gets ten seconds to recover between shuttles. At any point if he fails to reach the cone before the beep goes, he gets a first warning. Usually a player gets a few “reminders” to keep to the pace, but three official warnings generally marks the end of the test.
As a player moves up the levels, the time available to complete each shuttle diminishes, which means he needs to run quicker to reach the next cone before the beep. The player runs until he gets his three warnings, and the level achieved at that point is the test result.
Teams have different speed levels as qualifying marks. India have set 16:1 as the qualifying speed level, which means it is mandatory for their players to finish the first shuttle of speed level 16, which in terms of accumulated distance is 1120 metres. Pakistan’s minimum level is now 17:4; West Indies are at 19, and New Zealand probably have the highest level, 20:1.
