... production. The force-rate cost could contribute substantially to the overall cost of movements that require cyclic muscle activation, such as locomotion. We observed an increase in average net metabolic rate with frequency of cyclic torque production, which could not be explained by force–time nor...

... joint velocity calculated using the slack test method increased whereas V F decreased with muscle activation level ( P ≤0.03). Passive and low-level quick releases elicited higher V F values (≥41.8±10.7 cm s −1 ) compared with the ballistic condition (36.3±8.7 cm s −1 ), while quick releases applied...

... deletion in the Ttn gene, resulting in a putative 83 amino acid deletion in the N2A region of the protein. It has been suggested that the N2A region of titin is an ideal location for modulating titin stiffness upon muscle activation ( Nishikawa et al., 2012 ), because binding to actin at this location...

... of the sandfish during walking, burial and swimming, here we use high-speed X-ray and visible light imaging with synchronized electromyogram (EMG) recordings of epaxial muscle activity. While moving on the surface, body undulation was not observed and EMG showed no muscle activation. During subsurface sand...

This study examined muscle activation as a possible determinant...
