Balance

• Balance

  • the ability to neutralize forces that disturb equilibrium
• Static balance

  • The ability to hold a stationary position
  • E.g. completing a handstand, holding a stretch
• Dynamic balance

  • Ability to hold a moving position to execute an outcome
  • E.g.  Catching a wave whilst surfing, riding a skateboard
• BOS

  • the area bound by the outermost region of contact between body and support surface
• LOG

  • Imaginary vertical line passing downwards through the centre of gravity to the ground or surface the person is on
  • The closer the line of gravity to the limits of the BOS = the less degree of stability of the object
  • Movement is easier when LOG is outside of the objects BOS
• COG

  • Theoretical point in an object, located on either side inside or outside of the body, where all body's mass is equally distributed
• height of COG

  • The higher the centre of gravity above the base of support, the less stable the object is

  
• Mass

  • The greater the mass of an object, the greater its stability will be given, that all other factors are equal
  • Sumo wrestlers mass is harder to push over because of the weight
• Width of BOS

  • Greater the base of support, the greater the degree of stability
  • Sumo wrestlers having a larger base of support, feet are far apart
