Fundamental Concepts
the process of continuous sequential change to a specialized functional capacity.
What is development?
An individual constraint or system that holds back or slows the emergence skill because it develops more slowly than other systems.
What is a rate limiter?
An object as rest stays at rest and an object in motion stays in motion with the same speed and in the same direction until acted on by an external force.
What is Newton's first law of motion?
The act of moving from place to place.
What is locomotion?
Underhand, sidearm, and overarm are three different types of....
What are throwing styles?
The relatively permanent gains in motor skill capability associated with practice or experience.
Example!
What is motor learning?
Ex: riding a bike
A toddler takes short, quick steps because of their shorter legs. As their legs lengthen, their step length and walking speed changes.
This is an example of what?
Body Scaling
Law of action-reaction, states that for every force you exert on an object, the object exerts an equal force back on you in the opposite direction.
What is Newton's third law of motion?
What are you doing when completing the three steps?
1. Analysis
2. Planning
3. Positioning
Observing a skill
Foot action:
1. no step
2. homolateral step
3. short contralateral step
4. long contralateral step
What are the developmental changes in foot action for overarm throwing?
A qualitative advance in biological makeup and may refer to cell, organ, or system advancement in biochemical composition rather than to size alone.
What is maturation?
Development is driven by the interrelationship of individual, environment, and task
Hint: This is the framework that we use to understand this whole course.
What is the ecological perspective?
The acceleration of a person or object is proportional to the force applied to it and inversely proportional to its mass.
What is Newton's second law of motion?
-stability and balance are maximized over mobility
-arms are in high guard
-feet are out-toed and spread wide apart
These describe what stage of walker?
What are factors that influence different throwing and kicking abilities between children?
Gender
Muscle mass
The neural, physical, and behavioral aspects of movement.
Example!
What is motor control?
Ex: An experienced cyclist rides over a sudden patch of gravel, eyes spot the hazard, the brain processes the change to adjust
Name that theory....
Stage 1: Encoding
Stage 2: Storage
Stage 3: Retrieval
What is the information processing theory?
Whole body movements wherein the opposite arm and leg move back-and-forth together.
What is oppositional arm and leg movements?
Person propels self off ground with one or two feet and lands on two feet.
What is jumping?
Researchers often assess throwing by measuring what.
accuracy, distance, velocity
A characteristic of an individual, environment, or task that encourages some movements while discouraging others.
What is a constraint?
This strategy was created by Gesell and McGraw to "control" genetics while manipulating the environment.
What is the Co-twin Control Strategy?
The correctly timed sequence of movements an individual uses to successfully perform a skill.
What is an open kinetic chain?
What are two proficient jumping characteristics?
1. Preparatory crouch
2. Both feet leave ground at the same time
3. Arm swing is used during jump
What is the difference between product measures and process measures?
product (outcome): accuracy, distance, ball velocity
process (movement pattern): developmental sequence
