Motor Performance

Question 1

What is motor learning vs motor control?

Answer 1

Motor learning: is the aquisition and modification of learned movement patterns. Including movement, perceptual, and cognitive processes

Motor control: is the outcome of motor learning, the ability to produce* purposefull movement*

Question 2

What is a skill & a movement

Answer 2

Skill: is a task that has a specifc goal to achieve, and are goal-directed responses that consist of a body and/or limb movement (multiple processes)

Movement: behvaior characteristics of a specific limb or combination of limbs

Question 3

What is the differnece between a motor skill action, gross motor skill, & a fine motor skill?

Answer 3

Motor skill action: requires volunatry body/and or limb movemnet to achive a goal, goal directed, multiple processes involved, simple or complex

Gross motor: use large muscularture and less precision

Fine motor: small muscles with high levelk of precision (often in hand/finger movements)

Question 4

Difference between discrete, serial, and continuous motor skill?

Answer 4

• Discrete: definitive start and stop point
• Serial: puts several discrete movements toegther in a series of sequence (rowing) (donning a shirt)
• Continuous: nonstop, always are repetitive (

Question 5

Closed motor skills vs open motor skill?

Answer 5

• Closed:
• self-paced, fixed enviroment, predictable
• the object to be acted upon does not change duing the performace of the skill.
• The object waits to be acted upon by the performer (golf swing, diver off of a platform) (riding a stationary bike)
• Open:
• externally-paced, non-stable enviroment, the object or context changes duing the performace of the skill
• (dribbling a soccer ball, catching a baseball, playing in a basketball game)

Question 6

What are the 6 steps to analyzing the anatomical requirements of a skill?

Answer 6

1. name all the joints involved in the motor skill
2. record the starting position of each joint and the joint action that occurs
3. identify the segement that is being moved
4. identify the force for the movement
5. name the main muscle groups that are active
6. identify the type of contractions being utlilized by the main muscle groups

Question 7

Describe anatomical position?

Answer 7

Stand erect with elbows fully extended and palms facing forward. The GH joint has some ER and the forearm is in supination.

Question 8

What is the center of gravity?

Answer 8

imaginary point of the weight center of an object. In human’s the COG is anterior to the sacarl vertebra two (in anatomical position). Each segment in the body is acted upon by the force of gravity and has its own COG.

Question 9

What are the 3 cardinal planes and what does each do?
