Exercise instructions and explanazions (for film or instruction board) are laid down in the so-called exercise sheet as follows (figure 18):

• exercise number

• exercise sequence

• definition zone (movement rhythm)

• title

• target and anticipation areas

• movement instruction

• speech

• performance measurement

The symbolic and verbal information ist sufficient for the description of an exercise. A cinematic (pictorial) presentation is not necessary, but simplifies e.g. the understanding of the sequence of exercises and the organisation of the lesson. The pupils must be shown by means of the cibernatic presentation the spatial distribution and role attribution (hitter, umpire etc.). The division into a vertical and lateral aspect when watching the movemnet (e.g. in the film) is a ´natural view´ because of the invariance of G. Thus, the pictures from rear view structure the movement in the clearest way.

The independence of the vertical and the horizontal movement makes it possible to construct the exercise sequence from the easy to the difficult as a geometrical developement from clos to distant. If the movement rhythm ist constant, there is only a quantitative change of hte movement form which takes place parralel to this developement. So the player's state of performance can be determined by geometrical structures. For the four movement rhythms and their combination a modified line system for the target and anricipation areas is necessary. These lines fix the limits of the game within the space, on the spot, when walking and running as well as when playing with the partner, from a small to a great distance.

The determinability of the perception contents parallel to the action, which takes place in time, makes speech possible. The words are connected with the action as far as contents and time are concerned
