Reduction in the slope of the absolute force-MFR relationship and enhancement of voluntary force produced by a given MFR
A, mean ±s.d. values for the slope of the regression equation for absolute force-MFR relationship (see Figs 7 and 8). B, mean ±s.d. values for voluntary force when MFR was 15 Hz (as calculated from the regression equation relating absolute force and MFR). * Significantly different from the pre-immobilization value (P < 0.05).
