Presentation Transcript

  1. Biomechanics of Skeletal Muscle(Hamill ch 4, Cram Ch 2, pp 43-64) • Properties of muscle-tendon function • Extensibility and elasticity • Elastic and contractile components • Irritability and the ability to develop tension • Structural Org of Skeletal Muscle • Motor Unit

  2. Biomechanics of Skeletal Muscle • The motor unit and Electromyography (Figure from lab) • motoneuron & all innervated fibers • Fiber types I (SO), IIA (FOG), IIB (FG) • Muscle Fiber Type • Selective recruitment of fiber types – size principle: • SOFOGFG

  3. Recruitment proceeds from smallest fibers to largest (the size principle)

  4. Muscle Fiber Types
