KINE 4323/MOD 3- Theories of Motor Control Pt 1

a construct that helps us understand phenomena and the reasons why these phenomena exist or behave as they do

theory

a good theory must satisfy which 2 requirements?

accurately describe a large number of observations

make predictions about results of future observations

• describes unobservable structures or processes and relates them to each other and to observable events

• makes predictions for future events and in doing so, guides practitioners

a theory of motor control

• identify performance problems

• develop interventions

• predict effectiveness of interventions

• develop systematic practice methods

• create new interventions strategies

• evaluate new interventions

having a good understanding of motor skill performance allows practitioners to

what are the problems in motor control that need to be addressed?

degrees of freedom

context-conditioned variability (CCV)

perceptual motor integration

skill acquisition

• number of independent components of the system and the number of ways each component can vary

• How does the brain decide to move components of the arm?

degrees of freedom

• the capability of the motor system to enable an individual to achieve an action goal in a variety of situations and conditions

• brain does the more efficient way, when the movement goal is achieved in a variety of ways

motor equivalence

more planned movements—> more ______—>_______rt

dof, longer

more_______movements—>_______rt

complex, longer

how do skilled athletes decrease rt for complex movement tasks?

decrease the number of DOFs by grouping movements together

with _______, sprinters have learned to _______movements necessary to start sprinting

practice, simplify
