Yo-yo intermittent Recovery Test protocol 2 Stage The test result is expressed in stages, you can score between 1/2 or 1 stage. Players should pivot on the line at the moment of the beep (not quicker or slower). Yo-yo intermittent Recovery Test protocol 1 Stage
The starting speed is 10 km/h and each minute the speed is increased by decreasing the interval between the beeps, see the table below for ‘beep’ interval times for each one minute stage. The test is usually performed indoor and the speed of the participants is determined by the interval between the audio beeps played on a CD player, cassette or laptop. This makes the test very different from the standard shuttle run and is why coaches feel it is more representative for rugby. For this, the player jogs up-and-down two cones set 5 meters apart. After each individual shuttle the players have an active recovery period of 10 seconds. With this test the participants run back and forth across the gym or training pitch between two lines/markers set twenty meters apart until the players fails to reach the mark at the ‘beep’ on three consecutive laps or shuttles. The test is derived from the Shuttle Run Test.
Additionally, performances of the three Yo-Yo tests were seemingly better for football-trained than for non-sports active boys, providing evidence of construct validity.The Yo-Yo determines the maximum aerobic endurance of a player. In conclusion, Yo-Yo intermittent test performances and HR peak are reliable for 9- to 16-year-old footballers and non-sports active boys. Relative HR peak did not differ significantly between the groups in test and retest.
Intraclass correlation coefficient values for test–retest were excellent in both groups (range: 0.844–0.981). 515 ± 113 m) higher ( p ≤ .016), respectively for football-trained than for non-sports active boys aged 9–11, 12–13 and 14–16 years. The distance covered in the tests was 57% (1098 ± 680 vs. Peak heart rate (HR peak) was determined for all tests. the Yo-Yo intermittent recovery level 1 children's test for 9- to 11-year-olds the Yo-Yo intermittent endurance level 1 for 12- to 13-year-olds and the Yo-Yo intermittent endurance level 2 test for 14- to 16-year-olds. Within 7 days, each participant performed two repetitions of an age-related intensity-adapted Yo-Yo intermittent test, i.e. The purpose of this study was to examine the test–retest reliability and construct validity of three age-adapted Yo-Yo intermittent tests in football players aged 9–16 years ( n = 70) and in age-matched non-sports active boys ( n = 72).
