Week 2

What you need to know…
Why collect data and analyse activityDifferent methods of data collectionTypes of data collected: skill frequency,
movement patters, heart rate, W:R ratios, intensity
How each method is used to analyse activity

Data Collection
To collect a range of data about the fitness or physiological requirements of an activity or sport that can be analysed to determine strategies for enhancing physical performance

Why Collect Data & Analyse Activity?
1. To identify the fitness components of the sport
2. To identify the contribution of each energy system in the sport
3. To identify the muscles and muscle groups used in the sport
to be able to enhance performance

Which Data?
Four areas Physical
• Which energy systems are involved?• Which fitness components are required?• Which major muscle groups are used?
Mental Technical Tactical

Methods of Data Collection
Observation Useful on game day Particularly useful for identifying errors,
recognising patterns of play, making connections between actions and results
Observation and statistical data collection Concrete evidence Usually combined with observation
Videotaping combined with observation and statistical data collection Usually insufficient time during a game to look at
video After used post-game to slow down and replay

Types of Data Collected
Skill frequencyWork-rest ratiosIntensity chartsCombined intensity and work-rest ratioMovement patternsHeart rate

Skill Frequency
Data collected can be: Type of skill Frequency of skill Effectiveness of skill Muscle groups used
![Page 9: DATA COLLECTION & ACTIVITY ANALYSIS Week 2. What you need to know… Why collect data and analyse activity Different methods of data collection Types of](https://reader033.vdocuments.net/reader033/viewer/2022051820/56649ea35503460f94ba700a/html5/thumbnails/9.jpg)
Skill Frequency
Analysis Very useful to identify under which
circumstances and how often skills are used
Muscle groups used When combined with D & I fitness
components and energy systems Knowledge of results
• Information about outcome of performance (eg: in/out)

Work-Rest Ratios
Compares amount of time ‘working’ to the amount of time ‘resting’
What is ‘work’, ‘rest’?Very useful in team sports and for particular
positionsVital for considering
Contribution of the three energy systems Intensity of effort Method of training to be chosen Type of recovery to be chosen
![Page 11: DATA COLLECTION & ACTIVITY ANALYSIS Week 2. What you need to know… Why collect data and analyse activity Different methods of data collection Types of](https://reader033.vdocuments.net/reader033/viewer/2022051820/56649ea35503460f94ba700a/html5/thumbnails/11.jpg)
Intensity Charts
Breaking down movements (work) into intensities are recording
High Sprints, side step, shuffle, change of
direction, jumpMedium
Running (jog sprint)Low
Jogging

Combining Work-Rest Ratio & Intensity
When considering W-R it is vital to look at intensity
Work: what intensity? How long? Longest work? Shortest work?
Rest: what %? Longest rest? Shortest rest?

Combining Work-Rest Ratio & Intensity
Analysis Predominant energy systems Energy system interplay Helps to plan training specificity
![Page 14: DATA COLLECTION & ACTIVITY ANALYSIS Week 2. What you need to know… Why collect data and analyse activity Different methods of data collection Types of](https://reader033.vdocuments.net/reader033/viewer/2022051820/56649ea35503460f94ba700a/html5/thumbnails/14.jpg)
Movement Patterns
Reveal typical locomotor activities completed during a game or performance
Analysis Muscle groups used When combined with D & I
• Determine fitness components• Determine energy systems
Work-rest ratios Skill frequency Help to develop specific training programs

Heart Rate
Provide information on Intensity Training zone How will athlete is coping with workload How close athlete is to maximum effort
Heart rate zones Anaerobic zone
• >85% max HR Aerobic zone
• 70-85% max HR Recovery zone
• <70% max HR

Heart Rate
Analysis Primarily intensity When combined with D of work and rest
can help determine• Fitness components• Energy systems

Activity Analysis
Once the data has been gathered analysis can begin
Analysis involves skills such as Identifying patterns in data Recognising relationships and connections
between pieces of information Explaining Classifying Concluding

Games Analysis
Analysis of a team game to reveal the fitness components, energy systems, muscle groups and skills used so that the performance may be improved
