					      Biomechanics of Skeletal Muscle
         (Hamill ch 4, Cram Ch 2,
                 pp 43-64)
n   Properties of muscle-tendon function
    - Extensibility and elasticity
       • Elastic and contractile components
    - Irritability and the ability to develop tension
n   Structural Org of Skeletal Muscle
n   Motor Unit
    Biomechanics of Skeletal Muscle
n   The motor unit and Electromyography (Figure from
    lab)
     - motoneuron & all innervated fibers
     - Fiber types I (SO), IIA (FOG), IIB (FG)
n   Muscle Fiber Type
n   Selective recruitment of fiber types – size
    principle:
       • SO      FOG        FG
Recruitment proceeds
from smallest fibers to
largest
(the size principle)
