ABSTRACT

Background: Test instrument for flexibility is indispensable in several sports in the national development category, including aerobic gymnastics. However, the fact shows that no aerobic gymnastic flexibility test instrument is yet in the national development category. Purpose: This study aimed to examine the validity and reliability of the aerobic gymnastic flexibility test in the national development category. Design/ methodology/ approach: This research is a research & development supported by qualitative and quantitative approaches. The data collection was carried out with the Delphi technique, involving ten experts. The data analysis used Aiken's to test the validity and Cronbach alpha and Intraclass Correlation Coefficients (ICC) to test the reliability between raters. Results: The results show that the value of all items' Aiken's coefficient was above 0.70, so it can be said that all items were valid. With the Cronbach's Alpha value showed 0.919 and ICC showed 0.911, and each rater consistency was 0.507, it can be said that the instrument was very reliable. Conclusion: Therefore, it can be concluded that aerobic gymnastic flexibility test instrument in the national development category has high content validity and an excellent agreement between raters, with the consistency of each rater also quite well. For the test instrument to be much more precise, it is suggested to conduct empirical validity tests and reliably test-retests for athletes or non-athletes of the Age Group 1 category for 12-14 years old and Age Group 2 for 15-17 years old.
