1. 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]
