WebJun 1, 2010 · Force–length curves describe how a muscle's length affects its capacity for generating force. They consist of three parts: (1) an ‘ascending limb’ where force capacity increases as muscles go from short to intermediate lengths, (2) a plateau at intermediate lengths where muscles can maximize force production and (3) a ‘descending limb ... WebThe force generated by individual sarcomeres is approximately related to sarcomere length by an inverted-U function and this is sometimes used to describe the length–tension curve of the whole muscle.

Tendon is stiff (i.e., when tendon slack length is 0.1 times optimal fiber length) b. Tendon is compliant (i.e., when tendon slack length is 10 times optimal fiber length). c. Discuss your results. WebThe force that is generated by the muscle is then measured at each length increment using a force transducer, and the resulting data is used to plot the force-length curve. When the muscle is not stimulated (passive) the response is recorded(), when the muscle is stimulated (active) the response is recorded (x) This process is then repeated at ...

WebDuring a 35 N fingertip pinch, tendon forces can be measured up to 12 N whereas during active, unresisted finger motion, tendon force can reach approximately 35 N.
