Residual force depression is not related to positive muscle fascicle work during submaximal voluntary dorsiflexion contractions in humans

Residual force depression (rFD) following active muscle shortening is assumed to correlate most strongly with muscle work, but this has not been tested during voluntary contractions in humans. Using dynamometry, we compared steady‐state ankle joint torques (N = 16) following tibialis anterior (TA) m...

Description
Summary:Residual force depression (rFD) following active muscle shortening is assumed to correlate most strongly with muscle work, but this has not been tested during voluntary contractions in humans. Using dynamometry, we compared steady‐state ankle joint torques (N = 16) following tibialis anterior (TA) muscle–tendon unit (MTU) lengthening and shortening to the time‐matched torque during submaximal voluntary fixed‐end dorsiflexion reference contractions (REF) at a matched MTU length and EMG amplitude. Ultrasound revealed significantly reduced (P
