Fig. 3.

Mean values (±SE) of the voluntary time torque integral over the first 40 ms (TTI₄₀) after torque development (vTTI₄₀; a) and the sEMG amplitude 40 ms before the onset of torque development (RMS_−40–0; b) obtained during 56 days of bed rest (BR). For each session, both vTTI₄₀ and RMS_−40–0 are expressed as a percentage of the corresponding values at the steady-state maximal voluntary torque (MVT) of that session
