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.

Performance data

Tactical performance

data

Physiological performance

data

Patterns of play

Technique based data

Skill execution

Allowance for coach

intervention

Dominant energy

systems

Intensity data &

work to rest ratios

Relevant fitness

components

Major muscle groups

used


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.


Methods of data collection

Direct Observation

Digital Recording

Mobile Applications

Other technologies

Wearable technologies


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.

Digital recording

Advantages and disadvantages of digital recordings


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)


Ability to store and archive data Can be difficult for one person to both view and record data


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


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


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


Restricted to certain settings – e.g. stadiums
