VCE PHYSICAL EDUCATION – UNIT 4 AOS 1
Presented by Chris Hudd
Study design dot points:• Activity analysis, including skill frequencies, movement patterns, heart rates and
work to rest ratios
ACTIVITY ANALYSIS

Theory summaryAn activity analysis aims to gather sport specific physiological data through a record of performance via viewing or recording of an individual. This information is then analysed to determine the physiological requirements of the sport, and therefore form the basis of more effective and specific training programs.

What can this information be used for?Theory summaryInformation gathered in an activity analysis can be used to:
• Set individual and team goals;• Structure training sessions to enable the athlete to best meet the demands of the sport;• Provide feedback for players and compare against team and competition benchmarks.

Theory summaryThe highly practical, and simple process of coaches and trainers observing activities and then make decisions about the demands of the game based on what they see.
Direct observation
Information gathered via direct observation
Locomotion patterns – how and where an athlete moves
Intensity of activity
Skill frequencies
Muscle groups, and muscle movements utilised
Tactics and/or team plays implementedSource: https://www.flickr.com/photos/gerlos/3119891607

Advantages and disadvantage's of direct observation
Advantages Disadvantages
Ability for coaches/athletes to implement immediate change if required
Highly subjective data collection method
Highly practical in a variety of settings Memory limitations associated with observing for long periods of time
Labour intensive ie difficult to view and record observations at the same time
Difficult to observe every single aspect of a sport at a “live” pace
Hard to observe over larger playing/race areas
Difficulty associated with observing multiple athletes at the same time

Theory summaryCoaches and trainers observe activities, with accompanying statistical information, providing objective data that results in more specific and effective feedback for their athletes.
Direct observation with statistical support

Theory summaryThis method involves the recording of a match, race or training session by a digital video camera, smart phone, or tablet.
This allows for coaches, trainers, and athletes to view, replay, slow-down and freeze-frame the footage as often as needed.

Advantages and disadvantages of digital recordings
Advantages Disadvantages
Ability to store and archive footage Labour intensive process – filming, editing etc
Ability to replay at any time Expensive
Ability to share and transmit footage easily Trained equipment operators often required
Computer programs (Hawkeye etc.) can process footage for further analysis
Difficulty associated with recording sports that cover large areas
Increased accuracy when compared to direct observation

Theory summaryApplications, such as Easy tag below, are an easy and accessible way of recording accurate, objective data for later analysis. The use of smart phones and tablets also carry the advantages of being portable, convenient, accessible and low cost.
Mobile applications (Apps)

Advantages and disadvantages of mobile applications (Apps)
Advantages Disadvantages
Ability to store and archive data Can be difficult for one person to both view and record data
Increased accuracy when compared to direct observation
Difficulty associated with recording sports that cover large areas
Ability to share and transmit data easily Difficult to view multiple players at the same time
Ease of data collection via app
Low cost
Can be used in a variety of settings

Theory summaryWearable technologies include, fitness trackers, smart watches & phones, GPS tracking devices, heart rate monitors, and Radio frequency identification chips. These innovative technologies are constantly evolving with regards to the data captured, the ease of data collection, and the interactivity an individual can have with their data.

Advantages and disadvantages of wearable technologies
Advantages Disadvantages
Ability to store and archive data Expensive devices
Can be used in the field, and other large areas Slight discomfort in wearing some models
Can record multiple people at once Interference from nearby devices
Increased accuracy when compared to direct observation Not all models are waterproof
Combine movement patterns with intensities Technical operators of equipment is required
Ability to identify fatiguing athletes based on decrement in performance
Ability to share and transmit data easily
Ease of data collection via device

Theory summaryAerial video technologies including, Spidercam, Skycam, and Drones are allowing coaches and trainers a birds-eye view of individual and team performance. The cameras suspended from stadium roofs are able to alter the viewing angle for spectators, for entertainment purposes, but also for the use of coaches and trainers to focus on individual’s skill execution, and team movement patterns.
Methods of data collectionOther technologies

Advantages and disadvantages of other technologies
Advantages Disadvantages
Visibility of all players Expensive equipment
Can record multiple people at once Could be intrusive to sport
Alternate angles to view provides further biomechanical analysis of individual
Technical operators of equipment is required
Increased accuracy when compared to direct observation
Restricted to certain settings – e.g. stadiums
