Test and Re-Test Reliability of the Special Judo Fitness Test

Abstract

Background. When analyzing the available literature, we found differences and considerable variability in the Special Judo Fitness Test (SJFT) reliability methods. Problems and Aim. For this reason, we have set our goal to determine the reliability and measurement error of all parameters by SJFT. Methods. The research sample consisted of 15 judo athletes (17.13 ± 1.96 years, body height 174.4 ± 10.64 cm, body weight 72 ± 15.37 kg) who trained in judo on average 8.73 ± 2.12 years in two different Slovak judo clubs. The results were processed using interclass correlation analysis and measurement error percentage. Results. Our results indicate poor reliability for HR 0 (α= 0.374, Err = 4.2 %) and moderate reliability for the following parameters: the number of throws in section A (α = 0.641, Err = 5.9 %), section B (α = 0.512, Err = 6.0 %), and section C (α = 0.644, Err = 5.9 %), respectively. Moderate reliability was also found for the total number of throws (α = 0.687, Err = 5.1 %). Good reliability was found for HR 1 ( α = 0797, Err = 3.5 %) and SJFT index ( α = 0.807, Err = 4.5 %). Conclusions. According to the results of this study, by testing the special level of judo fitness, as well as its changes, we recommend using the HR 1 and SJFT index as good reliable parameters.
