Summary of the frequency results obtained with a load corresponding to different percentages of maximal voluntary contraction, along with a constant load of 6.5 kg, over two testing sessions.

Coefficients of reliability are also displayed. MASMVC = musculo-articular stiffness measured with a load corresponding to a percentage of maximal voluntary contraction; MASABS = musculo-articular stiffness measured with a constant absolute load; T1, T2 = testing session number 1 and 2; CV = coefficient of variation; SEM = standard error of measurement; CL = confidence limits for CV and SEM. * = significantly different from MASMVC60% (p<0.05).
