Knudson and Morrison Flashcards
why do coaches analyse performance
What an athlete is doing right
What an athlete is doing wrong
What key aspects need attention
What training activities are needed to rectify faults
To track athletes progress
context for analysing technique
laboratory analysis
field analysis
competition analysis
laboratory analysis
Performance is analysed in a laboratory to vary or manipulate factors
Computerised analysis can be used
Fitness levels
field analysis
Performance in normal surroundings at training
Setting lines in vball
competition analysis
Performance is analysed in a during competition
In game
methods of analysis
quantitative
qualitative
quantitative analysis
This uses numbers and is objective
Body weight
Speed of ball
Height of jump
qualitative analysis
Is a description/analysis without using numbers
A systematic process of this is the Knudson-Morrison model
Is subjective
Good
Short
Poor
Knudson-Morrison model stages
Preparation
Observation
Evaluation
Intervention
Re-observation
preparation
Coach is concerned with developing a prerequisite knowledge base about the skill
The coach must know the points of technique required to perform the skill correctly
A checklist is usually prepared
Preparation
All movements that prepare the athlete for the skill
Stance for receiving vball
Execution
Begins when preparation stage finishes and ends when point of release/contact of ball
Doing the skill
Follow through
All movements after execution
Holding the platform after ball is gone
observation
The systematic gathering of information about the performance
Decide what the best way is to gather information
Best angle
Direct observation or video
How many times
How close
evaluation
Identifies the strengths and weaknesses of the performer and prioritise in order of importance for correction and identify methods of improvement
Mark off checklist
List weaknesses in order of priority of correction
Determine methods of correction
Coaches must be aware of the cause and effect relationship when evaluating performance
Without recognising the cause, the problem would continue to occur
The receive has been shanked so the ball has gone the wrong direction
intervention
Involves providing feedback and corrections to the performer, usually in a practice setting, to improve performance
Coach explains what errors occurred, why and how to fix them
Beginners
Usually don’t know what they’re doing and require lots of external augmented feedback
Advanced performers
Often can detect and self-correct errors from their own intrinsic feedback so require less augmented feedback
reobservation
Observe the performer in a similar context to initial observation to see if the changes implemented have improved performance
Did they make an improvement or do they need further intervention
