U3aoS1 - Skill Acquisition Flashcards
Motor (movement) skill
Special form of skills that require movement of the body or limbs
Skill acquisition
The science that underpins movement learning and execution
- more commonly termed motor learning and control
Central nervous system is made up of…
Brain and spinal cord
Process of the central nervous system
Sensory input, integration and motor output
Internal sensory information
Visual, auditory, touch and proprioception
What is proprioception?
Body awareness in time and space
Perception action coupling
Working together of the central nervous system and muscles
- body perceives stimulus via the CNS
- message delivered via muscles to perform
Cues
Relevant and irrelevant
Level of success with intrinsic cues
Cognitive - not very successful at using intrinsic feedback
Autonomous and associative learners - much better at attending to external cues and using intrinsic information and feedback
Fundamental movement skills
Are the basic movements traditionally associated with activity
Fundamental skill list
- catch
- kick
- run
- vertical leap
- dodge
- leap
- ball bounce
- vertical throw
- punt
- forehead strike
- two - handed strike
Sport specific skills
More complex then FMS and are often a sequence of FMS
What are the stages of learning?
- cognitive
- associative
- autonomous
Characteristics of the cognitive stage
- beginner stage
- learning the mechanics of the skill
- substantial attention required to understand and perform skill
- many errors made
- learners have difficulty attending to external cues
- can’t make use of intrinsic feedback
What are cognitive learners focusing on?
- mentally trying to comprehend the movement requirements of the motor skill
- attention on movement production
- not yet developed error detection and correction
Performance of cognitive learners
- inconsistent performance
- stiff and unrelaxed movements
Associative Learning Characteristics
- movement patterns become refined
- intrinsic feedback for error correction
- increased awareness of environmental and external cues
- aware of tactical information
Associative learners practice type
Blocked and random practice
Feedback type of associative learners
- Augmented
- Internal feedback beginning to develop
Movements of associative learners
- refine technique and movement pattern
- more consistent, make fewer errors
- can detect cause of some errors
- develop strategies to eliminate them
- more attention to external stimuli
Autonomous stage characteristics
- automatic stage
- little attention required
- can make use of intrinsic senses
- focus on developing strategies and tactics
Practice type for autonomous learners
- Random
Feedback type for autonomous learners
Internal - knowledge of performance
Movement and awareness of Autonomous learners
- automatic skills
- detect and correct errors
- performance variables are small
- focus on tactics
How are skills classified?
Based on characteristics
- assists skill session planning
- evaluate performance
- give appropriate feedback
What is movement precision referring to?
- fine motor skills
- gross motor skills
What is type of movement referring to?
- discrete
- serial
- continuous
What is predictability of environment referring to?
- open
- closed
What are fine motor skills?
The use of small muscle groups to perform skills that require precision.
Example of fine motor skills
- darts
- hookey
- spin bowler
- golf
- netball
Gross motor skills
The use of large muscle groups to perform skills that require strength, power and force
Gross motor skill examples
- long jump
- footy kick
- batter in cricket
Define discrete skill
- movements of short duration
- clear beginning or end
Examples of a discrete skill
- kicking a soccer ball
- golf swing
Define serial skill
Series of discrete skills linked to create a more complex skill
Serial skill examples
- triple jump
- tennis serve
Define continuous skill
- no clear beginning or end
- movement continues for as long as performer wishes
- repetitive action of same movement
Continuous skill examples
- run
- swim
- cycle
- row
What are closed skills?
- predictable environment
- self-paced
- determined by athlete
What are open skills
- changing/unpredictable environment
- externally paced
Note: some sports more open then others
What is practise distribution?
Ratio of time spent actively practicing compared to time resting and listening to instructions
- frequency/duration
