Data Collection
Why collect data? Determine fitness and physiological
requirements of an activity or sport. Data is usually based on elite
performers and can require specialist equipment such as GPS trackers.
Individuals or teams can narrow the gap resulting in improvements.
What does the data show? The data helps determine what skills
and attributes that are needed in a particular sport for a successful performance.
VCE Physical Education - Unit 4
Useful Information for Coaches
What information would be useful for an athlete or their coach?
1. Physical* – Physiological fitness required
2. Mental – Psychological preparation/ ability to cope with game day pressure
3. Technical – Skill level under fatigue and pressure
4. Tactical – Decision making under pressure.
We will concentrate on the physical information;
Fitness components Energy systems Muscle groups and anatomy. Movement patterns Work to rest ratios Opponents strengths and
weaknesses Biomechanics Training principles
Methods of Data CollectionData collection and activity analysis
VCE Physical Education - Unit 4
ObservationObservation Individual sports are easier to observe than large team sports Monitors give feedback to the athlete in regards to their
performance. This feedback can then be used to make adjustments during training.
Quality of observations Experience and knowledge in the particular sport will benefit
observational data. Results can be affected by prejudice, perceptions and
conditions the observations were made under.
VCE Physical Education - Unit 4
Observation or Spectator?Observer or spectator? Spectators can be useful observers as they follow the flow of the game. Coaches need to also selectively attend to each of the their players to
watch for off the ball positioning.Observation Panel A number of panel members can be used to observe in specialist areas This allows for immediate feedback to the team. However ‘group think’
may be used to please the coach

Video taping combined with observation and stats
Advantages; More reliable than observation only Allows passages to plays to be
analysed in detail Athletes need to be keep in view at all
times to judge physical requirements Videos can be played at various speeds
when analysing skill errors Serves as a future comparison and
possibly as a motivator (Eg. Grand final win or loss).
Television has designed new inventive ways of viewing sport which provides coaches with some useful information eg. Stump cam.
VCE Physical Education - Unit 4
Summary
Observation only Immediate feedback However, no hard evidence to
reviewObservation and stats Concrete evidence to review in
the form of stats.Video recording and stats Video footage only used after a
game – no immediate feedback. Excellent for game review.
Types of Data CollectedData collection and activity analysis
VCE Physical Education - Unit 4
Interpreting the Data
Once the data has been collected, the analysis can begin.
Analysis requires; Identifying patterns in the
data Connecting pieces of
information Explaining and classifying
series of data.
The analysis of data can determine;
Appropriate diet Training method suitability Training cycle success Warm up and recovery
effectiveness
VCE Physical Education - Unit 4
Skill Frequency
Skill frequency charts are used to record the types of skills used and how frequently the occur. The effectiveness of each skill can also be recorded.
Skill frequency charts More relevant to technical data rather than physical Player is able to get feedback on their results Some information on fitness components could be extractedEg. Number of changes of direction could determine use of agility.Tennis Chart

VCE Physical Education - Unit 4
Movement Patterns
Suited to free range movement games.
Requires the charting of a player and plotting their movement details over a period of time.
Information can then be used in statistical grids.
GPS is now being used in major sports (See picture)
VCE Physical Education - Unit 4
Movement Patterns
Useful in determining muscle groups used.
Needs to have intensity and duration information to determine energy system and fitness components
Video analysis is better for analysing movement patterns
VCE Physical Education - Unit 4
Sample Movement Pattern
VCE Physical Education - Unit 4
SPI Elite (GPS Sports Product)
GPSports technology provides objective information on a player's speed, distance travelled, changes of direction, impacts and heart rate.
This information can then be used to modify training volumes and intensities and compare player or positional work-rates and work-loads.
VCE Physical Education - Unit 4
Work to Rest Ratios Compares the amount of time working in comparison to time
spent resting. Common ratio is 1:3 in team games Useful in determining contribution of energy systems and
the type of training to be used. Different positions in team sports have different work to rest
ratios
VCE Physical Education - Unit 4
Combined Work-Rest Ratio and Intensity
Intensity Charts Symbols are allocated to
the intensities observed during an activity or game.
The chart could use symbols such as (H) high, (M) medium or (L) low intensity.
Set intervals can be used. Very useful in determining
energy systems and fitness components
Combined ChartsRequires constant monitoring
of the athlete; Observing intensity levels
and duration Observing length of rest
periods before next action session
Gives an accurate account of energy system interplay.

Heart Rate Zones
HR monitors use is widespread in sport.
Athletes should train in the training zone.
Max HR = 220 - age1. Anaerobic zone –
85% max HR2. Aerobic zone – 70-
85% max HR3. Recovery zone –
Below 70%
VCE Physical Education - Unit 4
Heart Rate Data
Heart rate data Determines intensity only Needs additional data on duration and work-rest ratio to be
useful.See table 8.10 p.188See tables 8.12 & 8.13 p.189

Pedometers
Can be used to measure; Distance travelled Calories expended HR (In more expensive models)Commonly used as a motivational
tool.

Observation and Statistical Data Collection
Advantage of additional statistical data; Evidence that supports observational informationEg. Stopwatch and recording sheet.Technology is being used to collect and collate data more
rapidly.Eg. Virtual spectator and champion data.
