Classification of Motor Abilities and Motor Skills Notes

Differentiate between different classifications of motor abilities: Understanding the underlying capacities that facilitate movement.
Differentiate between different classifications of motor skills: Identifying how movements are categorized based on continuity, precision, and environment.

Ability: Refers to the general capacity to learn and perform skills.
- One CAN have an ability without possessing a specific skill.
- One CANNOT have a skill without the underlying ability.
Motor Learning: This process transforms abilities into motor skills.
- It is dependent on experience (e.g., practice).
- It is mediated by neural adaptations (plasticity).
Different Combinations of motor abilities can be used to learn motor skills:
- Everyone has a unique combinations of abilities
- Different combinations can lead to successful learning and performance of a motor skill

Abilities are broadly classified into three categories:

Physical: These involve anatomical and physiological abilities, such as strength and endurance.
Psychomotor: These involve perceptual and cognitive abilities, such as decision-making and dexterity.
Psychological: These involve behavioral and emotional abilities, such as motivation and confidence.

Category	Description	General Examples	Example Motor Skills
Physical Proficiency	Physiological, anatomical, and biomechanical characteristics	Lung capacity, fiber type, muscle strength, tissue strength, immunity, $VO_2max$ , stature, bone mineral density, postural control, and balance	High jumping, marathon running, playing soccer, operating a jackhammer
Psychomotor	Perceptual and cognitive processing, perception-action coupling speed, and decision-making	Motor reaction time, limb coordination and timing, movement precision, dexterity and arm/hand steadiness, knowing spatial orientation (kinesthesia), hand-eye coordination	Catching a ball, dancing, driving, playing a musical instrument, playing soccer, operating a jackhammer
Psychological	Behavioral and psychological characteristics; emotional control, cognition, and information processing speed	Memory capacity, visualization quality, attention control, pattern recognition, coherent and rapid information gathering	Pitching, volleyball libero, driving, playing soccer

Talent: The combination of motor abilities and skills that underlie performance.
Talent Identification: This involves measuring current abilities and skills to predict future performance.
Key Limitations of Talent Identification:
1. It is difficult to measure psychomotor and psychological abilities accurately.
2. It is difficult to identify the specific combinations of motor abilities and skills that will lead to expert-level performance.

Classifying motor skills is useful for several reasons:

It allows researchers to compare studies across different motor skills.
It allows for the prediction of learning and performance across different motor skills.
It allows for the generalization of research findings between motor skills that share similar classifications.

Motor skills can be categorized into three groups based on movement continuity:

Discrete Skills:
- Involve a single movement with a short duration.
- Have a distinct start and end.
- Examples: Throwing, kicking, and punching.
Continuous Skills:
- Involve the repetition of movements.
- No distinct start or end points.
- Examples: Cycling, swimming, and running.
Serial Skills:
- Involve multiple movements that combine both discrete and continuous skills.
- May combine highly different or highly similar skills.
- Examples: Gymnastics (different skills) vs. typing (similar skills).

Two classifications based on movement precision:

Fine Skills: Involve small movements using small muscles; characterized by high precision.
Gross Skills: Involve large movements using large muscles; characterized by low precision.
The Continuum of Precision:
- Fine and gross motor skills exist on a continuum.
  - Some fine skills may involve low precision.
  - Some gross skills may involve high precision.
- Many skills have both fine and gross components (e.g., pitching a baseball or throwing darts).

Two Classifications based on environmental stability:

Closed Skills:
- Self-initiated skills performed in a stable (unchanging) environment.
- Performers can initiate these skills at any time.
- Example: A golfer putting (the pin is not moving).
Open Skills:
- Skills initiated in response to changes in the environment.
- Performers must respond to changes in an external stimulus.
- Example: A baseball batter swinging in response to a pitched ball.

Open skills are often considered more difficult
- Reflects greater demands on the processing of environmental information.
- Many closed skills (e.g., gymnastics and dance) are extremely difficult.

Practice Progression Strategy: Moving from a closed environment to an open one.
- Initial Practice: Skills are practiced in a closed environment (e.g., hitting off a tee in t-ball).
- Subsequent Practice: Skills are then practiced in an open environment (e.g., hitting a pitched ball).

Gentile’s taxonomy combines three different classification schemes to provide a comprehensive look at motor skills:

Environment: Whether the skill is Open or Closed.
Body Movement: Whether the body is Stationary, Quasi-mobile, or Mobile.
Object Interaction (Manipulation): Whether the task is done with or without object interaction.
- Interactions are used to attain task goals but can also include avoiding contact.

Classification Dimension	Classification Decision	Reasoning / Regulatory Conditions	Simplification Ideas
Environment	Open	Players (offensive and defensive) are moving.	Practice without other players to make the skill closed.
Regulatory Conditions	N/A	Location of players, ball characteristics, speed of player movements, presence of a defender, boundary lines, and floor characteristics.	Remove or ignore difficult conditions like defenders or boundary lines.
Action: Body Transport	Yes	Player runs/walks up and down the court; involves forward, sideway, and backward movements.	Dribble in place or while slow walking to remove body transport.
Action: Object Manipulation	Yes	Handling the ball.	Use a larger ball with better grip to simplify manipulation.
