Table tennis reactive agility test, test-retest reliability

Abstract

Reactive agility is an important ability every table tennis athlete should have. Reactive agility is needed in all sports because it can help the body move backward, sideway steps, and forward quickly during practice or competition. Therefore a particular test instrument is required. Valid and reliable test instruments are needed to determine a table tennis athlete’s level and level of reactive agility. The results of previous studies showed Aiken’s V coefficient value above 0.76, while Cronbach’s Alpha and ICC are 0.875. Based on previous research, it was found that the results of the reactive agility test have content validity with Aiken’s quite good. However, a Test-retest reliability test is needed to strengthen the instrument. This study aims to assess the reliability of the product moment instrument reactive test agility of table tennis. Test-retest is used as a source of research data. The subjects in the study were 20 table tennis athletes aged 13-18 years. The test was carried out 2 times using a table tennis agility reactive instrument on different days. The time recorded during the test is research data. The data is presented in a descriptive statistical format, then analyzed using SPPS and reliability results using Pearson product-moment. The results showed that the product-moment correlation value was 0.956. based on the norms of reliability coefficients, the reactive agility test instruments specifically for table tennis have high scores or excellent categories. So it can be concluded that it can be relied upon to measure the reactive agility ability of junior and senior table tennis athletes.
