Abstract
To assess the reliability of the Agility K-test. METHODS: Young recreational athletes (n = 119, age 14.00 +- 2.74 years, height 162.49 +- 11.89 cm, mass 50.84 +- 11.39 kg) volunteered in the study.
The Agility K-test consisted of the subjects running at the indoor gym on hard wooden floor between cones positioned in a ""K"" pattern at maximum speed. The subjects started and ended running at the intersection of the ""K"" pattern.
A contact switch for time measurement was placed on the top of each cone which subjects touched with the right or left hand. The subjects performed three repetitions with a 10-minute rest in between repetitions of the Agility K-test once a week over a period of two weeks, then two repetitions with a 10-minute rest the week after.
The time of test execution was measured in seconds. The reliability was measured with the intraclass correlation coefficient.
RESULTS: The young athletes achieved a time of 12.69 +- 1.13 s in the Agility K-test. The intraclass correlation coefficient of the K-test ranged from 0.83 to 0.99 across eight trials.
CONCLUSION: The results indicated that the Agility K-test is a highly reliable test for use with young-aged subjects of recreational athletes
