U4AoS1 - Activity Analysis Flashcards
What is an activity analysis?
Most important step in development of a training program
How does a coach use an activity analysis?
Enables coaches/performers to make links between training and actual performance
What does an activity analysis involve?
Recording/illustrating physical demands on performer in competitive setting
Physical demands can be translated into training
Who/why are activity analysis important for
Elite athletes - they exhibit movements and skills that are more likely to lead to optimal performance
What is the key to success?
Specificity
- helps coaches gain specific knowledge
- used to design tailored training programs
- select specific fitness tests
Element of an activity analysis
- Heart Rate
- Work to rest ratio
- Movement patterns
- Skill frequency
Focus on the physiological requirements
Steps to designing a specific training program
- Activity analysis
- Determine physiological requirements
- Conduct specific fitness tests
- Design training program
- Post tests
- Evaluation
Why do we use an activity analysis?
First step in the effective development/implementation of strategic training programs (collection of data in games)
Methods of collecting data
Direct observation and digital recording
Advantages of direct observation
- practical
- coach can make immediate changes
- player fatigue easier to identify
Disadvantages of direct observation
- low accuracy
- subjective information
- memory reliance
- hard to observe all aspects of game
Advantages of a digital recording
- high accuracy
- objective data
- data can be reviewed
- replayed
- eliminates recall limitations
Disadvantages of digital recording
- less practical
- costly
- time consuming
What does a digital recording focus on?
Focus on isolated aspects
Concentrate on key areas for improvement
What data can be collected in an activity analysis?
- skill requirements
- work rests ratio
- distances/speed travelled
- movement patterns/type/direction
- intensity
- muscle groups
What sports are best suited to an activity analysis?
Team/intermittent sports
Analysis of continuous activity limited to HR and intensity
Why should highest level of performance be observed?
Allows for greater accuracy in data as it provides information on how to achieve optimal performance
What is data collection?
Process of gathering information.
First step to activity analysis
Methods of data collection
- digital= observation
- digital recording
- GPS tracking
Direct observation
- subjective
- how athlete moves
- intensity
- skill frequency
- muscle groups that need conditioning
- no supportive data
Digital recording
Statistical data can be recorded live, gathered and analysed after an event
Preferred method
Immediate analysis programs make it more efficient
What does GPS use?
satellite to identify position and movement
What does GPS stand for?
Global positioning system
What does GPS measure?
- distance/frequency
- duration at speed
- speed/acceleration
- intensity
- paths taken
What are movement patterns best suited to?
Team sports on large playing fields
How are movement patterns recorded?
GPS and manually
What information does analysis of movement patterns provide?
Highly accurate information required to develop training programs
- determine predominant energy systems/fitness requirements
What does movement patterns reveal?
Typical activities completed
- determine distance of efforts
- distance of sprints determine energy fitness component
What is recorded as part of movement patterns
- Type
- Duration
- Distance of movements
Locomotor recording sheet
- basis of statistical recording sheet
- seperate sheet for each time period
Advantages of GPS
- efficient
- record multiple athletes at once
- data easily stored/converted
Disadvantages of GPS
- expensive
- limited to outdoor activity
What sports is skill frequency best suited to?
Intermittent activities
What information is provided by skill frequency?
-predominant fitness components
- muscles /groups
- joint actions
Benefit of skill frequency analysis
specific tests/training programs, replicating physical components
Skill frequency tables
AKA stats
- direct observation
- frequency/effectiveness of skill execution
Muscle use analysis
- must be done in isolation
- relies on subjective observation
- major muscle groups used
- speed of muscle contraction
- flexibility
What sports is heart rate best suited to?
Continuous
Heart rate telemeter
provides data on HR response to physical activity
What does HR measure?
Estimate PA as energy expenditure, O2 uptake based on linear relationship
Role of energy systems
Benefit of HR
low participant burden
Disadvantage of HR
calibrate device to the individual
Limitation of HR
low intensity relationship between HR and intensity not linear
Factors affecting HR
stress, fear, anxiety, excitement
could cause false reading
What is Work to Rest Ratio
Time working and resting Ratio between each state and relative exertion levels
What information is obtained from work to rest ratios?
Energy systems and intensity
- Methods of training, work intervals, rest intervals
What is considered rest?
Standing still, walking, slow jogging
Manually recording W:R
record work efforts on stopwatch and rest periods on another, note intensity
Combine with HR monitor for intensity
What to analyze in W:R ratio
- total work/rest time
- avg work time per effort
- longest work/rest time
What sports are best suited W:R
Intermittent
Disadvantages of W:R
time consuming
difficult to collect and analyze information
