RELIABILITY AND VALIDITY OF COUNTING AND SPEED TEST CUSTOM-MADE DEVICE IN TAEKWONDO ROUNDHOUSE KICKING TEST FOR YOUNG TAEKWONDO ATHLETES

Abstract

The purposes of this research were to examine reliability and validity of constructed custom made 30-second roundhouse kicking and speed test device for young Taekwondo athletes. The sample in this study comprised eighty-five male and female adolescent Taekwondo athletes aged 12-17 years from the northeast region of Thailand, who had a black belt qualification and at least one-year experience in competition. Content validity of created device were checked by three experts. Then, the reliability of constructed device was tested from 30-second roundhouse kicking skill test. Subjects performed kicking at the target as quickly as possible and as many times as possible, and test was performed twice. The statistics used in the data analyses were mean, standard deviation, the index of item-objective congruence (IOC), the intraclass correlation coefficient (ICC), and the Pearson correlation coefficient. The significance level was set at .05 The results revealed high content validity index of constructed device at .91. The reliability of the constructed device in counting the number of roundhouse kicks was .886 (p < 0.05) and .819 (p < 0.05) for kicking speed. This study demonstrated the reliable and validated custom made 30-second roundhouse kicking and speed testing device, it is feasible instrument for further use in kicking skill test among young Taekwondo players.
