... =45.362, P <0.001). In contrast, there was no significant relationship between absolute rFD and SSN (SOL: R 2 =0.051, P =0.228; EDL: R 2 =0.107, P =0.073), fascicle length (SOL: R 2 =0.012, P =0.565; EDL: R 2 =0.104, P =0.077), or muscle length (SOL: R 2 =0.0004, P =0.914; EDL: R 2...

... preferred and fast walking speeds. We quantified the length changes and velocities of the TA muscle–tendon unit (MTU) and its fascicles across the stride at each speed. Fascicle length changes and velocities were relatively consistent across speeds, although the magnitude of fascicle length change differed...

...Logan Wade; Glen A. Lichtwark; Dominic J. Farris ABSTRACT Muscle contractile mechanics induced by the changing demands of human movement have the potential to influence our movement strategies. This study examined fascicle length changes of the triceps surae during jumping with added mass or...

Published: 01 August 2018
...Avleen Randhawa; James M. Wakeling ABSTRACT When pennate muscle fibres shorten, the transverse deformation of fibres results in an increase in pennation angle of fascicles (bundles of fibres) and transverse deformation of muscle belly. Transverse shape changes of a muscle can influence force...

... walking, a greater amount of active plantar flexor fascicle shortening early in the stance phase occurred and was transitioned through series elastic tissue stretch and recoil. Reorientation of the leg during early stance for acceleration allowed the ankle and whole soleus muscle–tendon complex to remain...

...-dimensional motion capture and a musculoskeletal model were used to determine lower limb kinematics that were combined with ground reaction force data in an inverse dynamics analysis. B-mode ultrasound imaging of the lateral gastrocnemius (GAS) and soleus (SOL) muscles was used to measure muscle fascicle...

... and kinetics were determined using motion capture and ground reaction forces. Also measured were gastrocnemius medialis (GM) muscle electromyography and GM muscle fascicle length using ultrasonography. GM muscle fascicles actively shortened during the touch-down phase of stair descent in all...
