Biomechanics of Human Movement

1
Biomechanics of Human Movement

• Balance, Follow Through, Leverage (levers)
  Torque, and Weight Transfer

2
Balance

• Definition
• Ability to stay in a point of nothingness with no
  outward tension
• Examples
• Defensive stance
• Medicine ball push ups.

3
Pictures of Balance

• Erectors, quads, and abs are used for balance

4
Follow Through

• Definition
• The completion of a form of movement that results
  in relaxation
• Examples
• Golf club ends up over the shoulder
• Tennis racquet ends up past the body

5
Images of Follow Through

• Muscles used (in golf) include quadriceps,
  hamstrings, abductors, adductors, obliques,
  gluteus maximus, latissimus dorsi, trapezius,
  pectorals, deltoids, triceps and biceps. Thats a
  LOT of muscles!

6
Leverage (Levers)

• Definitions
• The exertion of force by means of a lever
• A device you apply force to
• Example
• Bicep curl

7
Pictures of Leverage

• In torque, muscles act as effort forces to move
  loads.

8
Torque

• Definition
• A twisting force that often causes rotation
• Example
• Twisting Oblique Crunch

9
Pictures of Torque

• Trapezius, deltoids, abdominals, pectorals, and
  Latissimus Dorsi are used in torque.

10
Weight Transfer

• Definition
• Stepping power
• The ability to shift weight from one point to
  another.
• Example
• Throwing

11
Pictures of Weight Transfer

• Weight transfer works with the quadriceps,
  latissimus dorsi, and trapezius.
