Definitions

• Bio mechanics – application of the principles of mechanics / physics to biological organisms
• muscle action vs. function
  • action – motions produced by a muscle’s shortening; described in reference to axes and planes of body
    • – determined by architecture of joint and position of muscle around it
    • – pure mechanics which can be inferred
  • function – how the organism chooses to use a muscle
    • – can involve positive, negative or non- work (see below)
• agonists (Gr., contestant)– muscles with an identical action; usually restricted to single axis or plane of reference
