Abstract: The purpose of this study was to investigate the test-retest reliability of an isokinetic muscle endurance test. The right legs of twelve healthy males were tested on the Cybex Norm isokinetic dynamometer. The protocol consisted of 40 consecutive concentric knee extensions and flexions, performed maximally at an angular velocity of 120°/s. The subjects performed the test twice, five days apart. Total work, endurance ratio, 50% fatigue work, 50% fatigue time and 50% fatigue repetitions were obtained. A one-way analysis of variance (ANOVA) with repeated measures was used to examine the differences between test and retest values. The reliability coefficient was also established using the ANOVA results. The results indicated that measurements demonstrated high reliability (r>0.819). It could be concluded that the protocol used in the present study can be used to evaluate muscle endurance.
