Document Summary

Muscle fibers attaching to aponeurosis & tendon at. *only component of force aligned with tendon = contribute to joint torque & joint motion. *length change results in tendon stretch / joint motion. When pennate muscle contracts = muscle pulls on each tendon - l1-l2 < 2d. Distance that tendons move (2d) > slightly greater. 1-shortening velocity = the faster muscle fibers shorten -> the less force generate. * lower force generation at higher velocity of shortening. Length change of muscle fibers < slightly less than movement of tendons. On combined change in length of 1-muscle fibers + 2-tendon. When external force fe applied to body segment - causing segment to rotate. > amount of tendon stretch depends on muscle stiffness (tendon store energy better than muscle) *tendon stretches more when muscle strongly activated x(cid:1005) than when weakly activated/relaxed x(cid:1006) Antagonist - muscles on 1 side of joint = stretched agonist - muscles on other side of joint = shortened.
