Intra- and Inter-Rater Reliability of a Well-Used and a Less-Used IsoMed 2000 Dynamometer for Knee Flexion and Extension Peak Torque Measurements in a Concentric Test in Athletes

This study aimed to evaluate the intra- and inter-rater reliability of a well-used less-used IsoMed-2000 dynamometer for knee flexion extension peak torque (PT) measurements in concentric test athletes. Two isokinetic dynamometers were used, an old one that was new less-used. Thirty-seven weight-lifting athletes (12 female, 25 male) included this study. Both legs each athlete tested twice on at 60°/s 180°/s. The Intraclass Correlation Coefficients (ICC), Standard Error Measurement (SEM), Smallest Detectable Change (SDC), SDC% 95% limits agreement calculated IsoMed 2000 Intra-rater moderate excellent (ICCs: 0.516–0.928) muscle strength parameters, highest SDC SEM values 0.76 N/kg 0.28 N/kg, respectively. Inter-rater 0.519–915) 0.81 0.29 At least 89.2% obtained parameters fell within agreement. Our findings demonstrate intra Well-Used Less-Used Dynamometer Knee Flexion Extension Peak Torque Athletes.
