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.


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 Collection

Data collection and activity analysis


Observation

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.


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

Checkpoints


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.


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 Collected



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


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

Coursework 8.2


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)


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


Sample Movement Pattern


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.

http://www.gpsports.com/main.php


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


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%


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.188

See 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.
