Abstract: Twelve university females were studied to determine the reliability of four different methods of calculating concentric and eccentric peak torque (PT) and angle-specific torques (ASTs) for knee extension. Each subject was tested on the Kin-Corn isokinetic dynamometer on two separate occasions, performing five concentric and eccentric contractions at 60° PT and AST at 30°, 60°, and 75° were calculated by averaging the first three contractions, averaging all five contractions, taking the single best value of the first three contractions, and taking the single best value of all five contractions. Intraclass correlation coefficients derived from these calculations showed high correlation among the four methods. Additionally, z tests performed on correlation coefficients transformed to Fisher's Z revealed no differences between pairs of correlation coefficients. These data appear to show there is no difference among the four methods of calculating PT and AST.
