Lecture 19 - Analyzing Performance Flashcards
1
Q
what is a movement pattern?
A
- when many segments and joints move in concert
2
Q
what is technique?
A
- the way a skill is performed
3
Q
what is style?
A
- variations in technique
4
Q
what are the 5 constraints of skill/technique/style
A
- rules of the game
- boundaries of the game
- equipment limitations
- the environment
- simple physics
5
Q
what is a closed skill?
A
- a movement where you can easily predict what will happen
6
Q
what is an open skill?
A
- a movement where the outcome is not predictable
7
Q
what is a discrete skill?
A
- well-defined start and finish
8
Q
what is a continuous skill?
A
- does not have a well-defined finish
9
Q
what is a repeated discrete skill?
A
- has a start finish, but is repeated often and regularly
10
Q
what are the 3 phases of a skill?
A
- stretch shortening
- actual action
- stopping the motion once the action has been completed
11
Q
what must you evaluate when analyzing a skill?
A
- mechanical purpose
- biomechanical factors
- biomechanical purposes
- critical features
12
Q
what is ergonomics?
A
- reduce injury, overuse and boredom while optimizing speed/productivity (for repetitive physical activity)
