- Study of human motion from the standpoint of the physical sciences.
- Study of the Human body as a machine with regard to work and physical
performance derives its foundations in three major sciences:
- Biomechanics
- Musculoskeletal anatomy
- Neuromuscular physiology
|
|
3
|
- Study of muscles as they are
involved in the science of movement
- Both skeletal and muscular
structures are involved
- Bones are different sizes and
shapes, particularly at the joints, which allow or limit movement
|
|
4
|
- Improving human performance by
analysis of motion
- Help others perform safely,
effectively and efficiently
- Contribute to clinical and
ergonomic applications
|

- qualitative analysis
- quantitative analysis
- videotape recording
- other recording methods; force,
EMG, elgon

- Observation
- Compares
- Detects errors
- Corrects errors
- Evaluates results

- Describing the skill must be done
in a logical, systematic order by breaking the skill down into its
components
- Evaluating the performance of the
skill by determining whether and how the related anatomical and
mechanical principles have been violated
- Prescribing corrections based on
an appropriate identification of the cause or causes.

- Description of the motor skill performance
- 1. Primary purpose of the skill
- 2. Movement phases - starting and end points of each phase should be
identified.
- 3. Classification of the motor skills
|
|
9
|
- Maintaining erect posture
- Movement for exercise and fitness
- Giving motion
- To external objects
- pushing and pulling
- a. lifting and carrying
- b. punching
- Throwing, striking and kicking
|
|
10
|
- III. Giving motion (CONT’D)
- B. To one's own body
- 1. supported by the ground or other resistant surface
- b. locomotion on wheels, blades and runners
- c. rotary locomotion
- 2. Suspended and free of support
- swinging activities
- hand traveling on rings or
ladder
- unsupported - projected into
or falling in the air
- weightlessness
- 3. Supported by water
- Swimming
- aquatic stunts
- boating

- IV. Receiving Impact
- From one’s own body in landing from a jump or fall
- From external objects in catching, trapping, spotting, or
intercepting.
- V. Simultaneous-sequential nature of the motion
- simultaneous movements are where various segments move as one
- pushing, pulling, squatting,
lifting objects.
- all movements are directed
along a straight line
- sequential movements: throwing,
striking, kicking
- used when speed at impact or release is important
- use of segments in an orderly
sequence
- produce forces applied so that
the final segment moves along a curved path
- combined simultaneous-sequential
movements
|
|
12
|
- The following must be related in time to the phases of the motion
- Joint actions
- Segment motion
- Muscular involvement
- Types of contractions
- Neuromuscular considerations
- Anatomical principles related to
safe effective performance

- The mechanical aspects of motion
aid in describing the motion and in determining the causes of the
motion. Since the description of
motion, kinematics, deals with linear and/or angular displacement it may
also be fundamental to the definition of the phases of motion. Again, put the mechanical aspects in
the phasic organization of the motion.
|
|
15
|
- A. Balance
- regain stability
- attain mobility
- B. Locomotion
- travel from one point to another
- travel a prescribed distance
- travel a prescribed pattern
- C. Projection
- for maximum height
- for maximum distance (range)
- for maximum accuracy for optimum
speed and accuracy
|
|
16
|
- D. Manipulation
- of objects
- to reproduce a pattern
- of a resistance
- E. Maximum effort
- maximum speed
- maximum power
- maximum force
- III. Nature of forces causing or impeding motion
- IV. Mechanical principles that apply
- V. Violation of the principles
- hard to determine
- cause may be far from effect
- may need recording device
|

|
- Prescription - for improvement of performance indicate how the
performance should be changed so that the principles are no longer
violated.
- up to now the work has been
diagnostic
- the prescription for correction
requires ability to communicate to and instruct the student on how to
incorporate the changes in performance to produce the improved result
