Abstract:
The purpose of this research was to construct octagonal-specific agility step test in elite taekwondo athletes. The sample group was 200 taekwondo athletes aged 15-22 years old in Thailand. They were divided into black belt taekwondo athletes, who have experiences in national and international competitions of 170 people; there were 92 male athletes, and average age 17.04 + 1.72 years, 8.36 + 2.02 years of competitive experience.
There were 78 female athletes, average age 16.96 +1.88 years, 8.56 +1.49 years of
competitive experience, and general taekwondo athletes with qualifications below the black belt. They were 30 male athletes, average age 16.13 +1.25 years, with 1.96 + 0.71 years of competitive experience. They were selected by purposive sampling. The instrument used in this research is octagonal-specific agility step test created by the researcher, which was examined by an expert to determine the validity of the instrument and found the reliability by test-retest to determine the construct validity and found Criterion-Related Validity between the created test and the Nine Square Test, Hexagon Agility Test, and Taekwondo-Specific Agility Test (TSAT) by calculated Pearson-product moment correlation coefficient, statistically significant level at .05
The results found that the octagonal-specific agility step test in elite taekwondo
athletes have has validity at 0.96. The reliability was significantly higher (r=.806) at the .01 level. There was a correlation coefficient of reliability for octagonal-specific agility step test created by the researcher and the 9 Square Test, the Hexagon Test, and the Taekwondo Specific Agility Test were in moderate level, statistically significant at the .01 level.
In conclusion, a construction of octagonal-specific agility step test that the
researcher created can be used to measure and evaluate agility performance for
taekwondo athletes and can use for the selection of athletes and to continue develop taekwondo athletes later.
