- 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 VCE Physical Education - Unit 4

- Data collection and activity analysis

- Observation 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

- 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 VCE Physical Education - Unit 4
- Slide 7
- 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

- Summary Observation only Immediate feedback However, no hard
evidence to review Observation 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. VCE Physical Education - Unit 4

- Data collection and activity analysis
- Slide 10
- 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
- Slide 11
- 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 extracted Eg. Number of changes of
direction could determine use of agility. Tennis Chart VCE Physical
Education - Unit 4
- Slide 12
- 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
- Slide 13
- 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

- Slide 15
- 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
- Slide 16
- 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
- Slide 17
- 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 Charts
Requires 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. See table 8.5 p.181 See table 8.6 p.181 VCE Physical

- Heart Rate Zones HR monitors use is widespread in sport.
Athletes should train in the training zone. Max HR = 220 - age 1.
Anaerobic zone 85% max HR 2. Aerobic zone 70- 85% max HR 3.
Recovery zone Below 70% VCE Physical Education - Unit 4
- Slide 20
- Heart Rate Data Heart rate data Determines intensity only Needs
additional data on duration and work-rest ratio to be useful. See

- Observation and Statistical Data Collection Advantage of
additional statistical data; Evidence that supports observational
information Eg. Stopwatch and recording sheet. Technology is being
used to collect and collate data more rapidly. Eg. Virtual
spectator and champion data. VCE Physical Education - Unit 4
