INTRODUCTION TO BIOMECHANICS (BASIC DEFINITIONS) MUST KNOW

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
