The running speed from level 8 to level 2 1 is divided into 12, and the starting speed is level 8, which is equivalent to 1 1.5 km/h, that is, 40 meters (2×20 meters) can be completed in about 12.5 seconds. Different speed gears need to complete different groups of 2× 20m turn-back runs: 8, 10, 12, 13, 13.5, 14, 14.
The standard for reaching the standard is the third group 17 (57 groups with 2280m in total) after plain testing; The first group 17 (55 groups, 2200m in total) finished in plateau area. When the sound signal rings, players must run back to the line, otherwise they will be warned the first time and eliminated from the test the second time. Whoever finally completes the required number of groups is considered to have passed the physical fitness test.

YOYO physical fitness measurement was invented by a doctor of physical education in Denmark. It mainly simulates frequent movements such as acceleration, deceleration, emergency stop and turning in the competition, and tests the players when they reach the limit of physical fitness.
The specific criteria are as follows: the team members run in two groups with the sound of "beep, beep" within 20 meters, with an interval of 5 seconds, and the sound rhythm is constantly accelerating. The test speed of the team members starts from 8 speed until it is increased to 17 speed. When it reaches the speed of 17, it is close to the physical limit of the players. Players who can't keep up with the speed for the first time will be warned once and disqualified for the second time.
