Optimal muscle fascicle length and tendon stiffness for maximising gastrocnemius efficiency during human walking and running.
Muscles generate force to resist gravitational and inertial forces and/or to undertake work, e.g. on the centre of mass. A trade-off in muscle architecture exists in muscles that do both; the fibres should be as short as possible to minimise activation cost but long enough to maintain an appropriate shortening velocity. Energetic cost is also influenced by tendon compliance which modulates the ...
متن کاملKnee muscle forces during walking and running in patellofemoral pain patients and pain-free controls.
One proposed mechanism of patellofemoral pain, increased stress in the joint, is dependent on forces generated by the quadriceps muscles. Describing causal relationships between muscle forces, tissue stresses, and pain is difficult due to the inability to directly measure these variables in vivo. The purpose of this study was to estimate quadriceps forces during walking and running in a group o...
متن کاملInferring muscle functional roles of the ostrich pelvic limb during walking and running using computer optimization
Owing to their cursorial background, ostriches (Struthio camelus) walk and run with high metabolic economy, can reach very fast running speeds and quickly execute cutting manoeuvres. These capabilities are believed to be a result of their ability to coordinate muscles to take advantage of specialized passive limb structures. This study aimed to infer the functional roles of ostrich pelvic limb ...
متن کاملDifferences in muscle function during walking and running at the same speed.
Individual muscle contributions to body segment mechanical energetics and the functional tasks of body support and forward propulsion in walking and running at the same speed were quantified using forward dynamical simulations to elucidate differences in muscle function between the two different gait modes. Simulations that emulated experimentally measured kinesiological data of young adults wa...
متن کاملTrichinosis of psoas muscle.
There are isolated case reports of Trichinella spiralis infestation in animals from India. We report the first case in man from India. The nematode was discovered incidentally during drainage of psoas abscess.
