BIOMECHANICS APPLICATIONS
2
DEFINITIONS

• Biomechanics - mechanics of structure function
• Mechanics - statics dynamics
• Statics - nonmoving systems
• Dynamics - kinetics kinematics
• Kinetics - forces that cause movement
• Kinematics - describing motion

3
Kinetics - forces

• buoyancy
• centripetal
• elasticity
• fluid drag
• fluid lift

• friction
• gravity
• muscle
• pressure
• reaction

4
Kinematics- describe movement

• velocity - m/sec., degrees or rads/sec. (57.3?)
  
• acceleration - change in v OR change in direction
  
• displacement - in meters or degrees or radians
• momentum - M mv OR L I?

5
Efficient Movement

• minimal energy expenditure
• necessary for endurance sports and repetitive
  tasks in labor
• allows performer to endure longer
• allows performer to performer faster with less
  energy expended

6
Effective Movement

• not concerned with efficiency
• most appropriate movements to achieve OPO
  Overall Performance Objective
• most appropriate sequence of movements e.g.
  large parts then small parts
