Give Guthrie’s definition of skill
The ability to bring about predetermined results, with maximum certainty and minimum outlay of time or energy
Give three continuums
- Gross-fine
- Open-closed
- Discrete-serial-continuous
Give an example of a closed skill
Taking a penalty shot in netball in the D
Define coordination
The ability to use different parts of your body together efficiently relative to the task and environment
How can coordination be measured? (check exam questions)
- Quantitively
2. Qualitively
Define degrees of freedom
The individual elements and components of a system and the number of ways each component can act
How many joints are in the body?
100
How many muscles are in the body?
10,000
How many cells are in the body?
10 (14)
What does it mean to have lots of degrees of freedom?
The body has more movements and components that what is needed for any specific task. As a result there is a redundant amount of degrees of freedom, in that many won’t be used
What does Bernstein say?
He says that the body has too many degrees of freedom and that this must be controlled because so many are just left redundant
Do cognitive learners or young people have few or lots of degrees of freedom?
The performer is stiff and rigid because they have only a few degrees of freedom rather than using lots of elements in the body for movement
What is freezing?
This is when the performer or coach limits their movements to concentrate on a particular element of a skill
Give an example of freezing and who would use it
A cognitive learner, young person would use freezing. It could be when learning to dive sitting at the edge of the pool and only practicing the head and arm movements without the lower part of their body.
What is freeing/unfreezing?
This is when the performer begins experimenting with more movements, and so freeing some movements. This means the movements aren’t as rigid
Give an example of freeing/unfreezing and who would use it
Freeing/unfreezing would be used by an associative learner
What is exploitation?
This is when an athlete uses the environment to their advantage. This occurs when athletes have fully learned the movement and what works best
Give an example of exploitation and who would use it
Exploitation would be used by an autonomous learner. An example is using the springboard in gymnastics for a somersault or hitting the sweet spot on a golf club in golf to get more power
What is an open loop skill
This is when a movement happens so quickly, you can’t change the skill you just have to carry it out
Give an example of an open loop skill
A smash in badminton
What is a closed loop skill?
This is when you have time to adjust a skill depending on the situation and feedback
Give an example of a closed loop skill
Dribbling in hockey you have time to take into account where the opposition is, where your players are etc
What is the top down approach?
This is when the brain is the only thing that controls and imposes movements
Give two problems with the top down approach?
- Who controls what the brain controls and commands- something must control the brain
- Storage issue- the brain and body can only remember a certain amount of things and it does not have the capacity to remember every single movement the body can carry out
