Development of Agility Test Construction: Validity and Reliability of Karate Agility Test Construction in Kata Category

Abstract

Kata is a series of moves competed in karate that require agility in its movements. Purpose: This research aimed to determine the validity and reliability of karate agility test in kata category. Method: This was a developmental research. The data were collected using the Delphi technique, involving 7 experts and test-retest. The participants were 20 karate aged at least 20 years old who have practiced karate for 6 years and have won regional competitions. This was to determine the test of empirical validity and reliability. The content validity was calculated using the Aiken formula, the empirical validity was calculated using Pearson Product Moment, while the reliability was calculated using the Cronbach Alpha. Results: The results showed that the karate agility test in kata category had high validity and reliability. The Aiken results were as follows: Item (1) size has fit the karate in kata category with a value of V 0.85; Item (2) distance between cones has fit with a value of V 0.80; Item (3) equipment has fit with a value of V 0.80; Item (4) number of test repetitions has fit with a value of V 0.80; Item (5) test procedure has fit with a value of V 0.80; Item (6) safe instrument has fit with a value of V 0.85; Item (7) agility has fit with a value of V 0.85; Item (8) score taking has fit with a value of V 0.80. The results of Pearson product moment r-table were 0.444, r-count (test 1) was 0.927, r-count (test 2) was 0.903, significance was 0.000 < 0.05. Conclusion: It can be concluded that the agility test can be used to measure the karate agility in kata category.
