Very useful for both athlete and coach in 1) technical and tacticall aspects but also

2) physical requirements.

          

                       

Skill = Kick made

This form of data collection is best suited to games where movements are more “free range” and unpredictable.

Activities where charting movements of players is critical to development.

6 marks = 6min.

See page 176 Fig 8.7

Statistical representation of movement patterns and Skill frequency!!

Symbols are assigned to the intensities observed while an athlete participates in a game or activity.

I.E. an athlete working at OR◦ High =(H) Walk = (W)◦ Medium = (M) Jog = (J)◦ Low = (L) Run = (R)

Sprint = (S)

Pp 179 for an example.

To achieve these charts, typically one person allocated intensities while another notes the information into a table.

Read the last paragraph on Pp 179 for other methods….NOW.

Used to compare the amount of time working with the amount of time resting.

Calculate the total time working and resting and reducing this to the lowest number of times one figure contains the other.

E.G. 6min = work : 18min = rest gives a work to rest of 1:3.

This ration is common in team games.

One of the most important aspects to consider is how to define the terms “WORK” and “ REST”

Read page 180 (left hand side).

This is a very important type of data collection. It allows some conclusions to made about the energy systems that are activated because the following data is collected:◦ What intensity they are working at◦ For how long◦ Rest intervals.

1 Data can be gathered from movement patterns, intensity charts, skill frequency, heart rate, etc. In most cases it will indicate the frequency of usage of fitness components. If combined with information regarding duration of the activity being observed, estimations of energy system usage can be made.

2 Intensity and duration are critical data. Any strategy that reveals both of these will be effective. Heart rate combined with duration of work and rest intervals is the most effective strategy that is readily available to most athletes and coaches.

1. Activity analysis requires skills such as ability to observe, collect data, deduce, analyse, relate, predict and forecast.

2 Analysis can reveal the muscle groups, fitness components and energy systems used in a particular activity.

3 Movement patterns and skill frequency charts need additional information about intensity and duration before conclusions about energy systems and fitness components can be made.

4 When recording movement patterns, be sure that the athlete remains in view at all times and that the camera is sufficiently distant from the athlete so that reference points on the court/field/playing area can be seen. Also, record as much of the game as possible.

5 A work-rest ratio chart reveals the longest and shortest work and rest intervals, average work and rest, total work and rest, and work-to-rest ratio.
