WebA young biomechanist, Ted, is attempting to estimate a muscle's active force length curve. However, he cannot isolate the muscle of interest, but instead can only perform experiments on the muscle-tendon actuator as whole. He performs a series of trials where the musculotendon actuator is held isometric and tendon force is measured in steady state.

WebCompare the estimated active force-length curves you get this way with the active force-length curve of muscle alone when: (a) tendon is stiff (i.e., when tendon M E slack length 1/10 as long as optimal fiber length), FM FMO (b) tendon is compliant (i.e., when tendon slack length is 10 times longer than its optimal fiber length). WebWhen the muscle is stimulated to contract, the myosin head binds to the actin filaments, causing them to slide past each other and shorten the muscle fibers, this action produces force. * The peak of the active tension portion of the curve represents the maximum force that can be led by the muscle at a given length.

WebJun 1, 2013 · The dependence of muscle force on the length and velocity of muscle fibers has long been established (Bahler et al., 1968; Gordon et al., 1966; Hill, 1953).Many studies have shown that the length and velocity of muscle fibers can have a large effect on muscle force generation in various experimental assays, yet it is not fully understood how much … WebApr 8, 2024 · The curves are different depending on the action taken by each participant (Winter & Challis, 2010). ...
