Performance Analysis Flashcards
What are the 4 types of performance analysis?
Tactical, technical, physical, behavioural
Why do athletes take part in fitness tests?
- Establish a baseline
- To highlight any strengths and weaknesses
- Compare with opponents and norms
- To see improvements by making a specific training programme
- Retest and adapt if needed
What is Reliability?
A test is reliable if the results are consistent and can be repeated on different occasions. Should obtain the same or similar results.
What is Validity?
Validity is whether the test actually measures what is set out to. Validity is improved if the test is sport specific.
Can a test be reliable but not valid?
Yes
E.g a hand grip dynamometer will produce reliable results, it is not a valid test of leg strength because it measures hand grip.
What is the coaching process?
- Observation
- Analysis
- Evaluation
- Feedback
- Implementation
Then back to observation.
What are the reaction time observations?
Live observation What you see at the time 1 view, 1 watch Limited view - might miss them play Hard to supply accurate feedback Difficult to observe complex skills
What are the Data Collections steps?
- Identify strengths and weaknesses in performance
- Identify key priorities for improvement
- Plan training effectively
- Review, evaluate and make necessary adjustments to training
What is Qualitative data analysis?
Is taken from observations to describe performance (often opinion based)
What is Quantitative data analysis?
Is a collection of factual, numerical, data to establish accurate analysis.
What are the 3 types of video analysis?
- Frame by Frame (frame analysis)
- Split screen
- Slow motion
What are the advantages of video analysis?
- Coaches and athletes can see aspects of performance, instead of having to interpret numerical data.
- Cheaper video cameras are becoming available
- Can be adapted to film different aspects of a performance
What are the disadvantages of video analysis?
- The highest-quality are still very expensive
- Can be time-consuming
- Doesn’t provide numerical data
- Sometimes qualitative and subjective data
- High level of experience and knowledge is needed to maximise data and quality of videos
What method of analysis are used to analyse tactical performance?
- Notational analysis
What is notational analysis?
It is used when analysing team or individual performance based on key performance indicators.
What is a notational analysis example?
- Time in possession of the ball
- Successful passes
- Shots on goal
Heat maps can be used
What method of analysis is used analyse to technical performance?
- Biomechanical analysis
What is biomechanical analysis?
It is when you analyse the physical performance of a skill.
What is an example of biomechanical analysis?
- A gymnastics vault
- Slide tackle
- Free throw shot
What factors affect a a coaches perception?
- Favouritism
- Unconscious bias
- Coaches relationship with the player
- Past experiences
- Knowledge
What are the methods of analysis?
- Individual or team assessments
- Real time analysis
- Computer technology
- Video analysis
What are used for computer technology analysis?
- GPS
2. Heart rate monitors
What are lab based fitness tests?
Requires specialist technology and machinery to undertake and analyse results. They provide a DIRECT measure of fitness and results are very accurate.
What is an example of lab based fitness tests?
VO2 max testing - gas analysis
What are field based fitness tests?
They allow fitness tests to be performed on a wider scale. They provide an INDIRECT measure of fitness tests. So lack the same level of reliability and accuracy in results.
Advantages of field based fitness tests?
- Cheap, quick and simple
- Limited specialist equipment is required
- Results can be compared to norms.
- Multiple people can be tested at the same time
Example of field based fitness tests?
- Flexibility : sit and reach
- Cardiovascular endurance : MSFT
- Agility : Illinois agility test
- Balance : stork stand
What is aerobic capacity?
‘The ability to take in, transport and utilise oxygen to sustain aerobic or sub-maximal exercise’
What is VO2 max?
‘The maximum volume of oxygen that can be consumed and utilise by the body’
How do you test for VO2 max?
- Gas analysis
- MSFT
- Cooper 12 minute run
- (Hazard) step test
Factors affecting VO2 max?
- Age - muscles diminish with age
- Genetics - ability passed down from parents
- Gender (larger respiratory organs)
- levels of fitness
- Respiratory function
What is lactate threshold?
‘The point at which a performer can exercise without lactate accumulating in the blood’. The point at which OBLA is reached
What does OBLA stand for?
OBLA - Onset of Blood Lactate Accumulation
What does a high VO2 max indicate?
It indicates a high lactate threshold.
