The process of motor learning is long-lasting and, in terms of its effects, it consists of three basic phases: the phase of basic movement coordination, the phase of accurate movement coordination and the phase of movement coordination stabilisation under changeable and difficult circumstances.

In this phase of learning, an individual first learns about basic movements and is able to execute them only under favourable conditions and with sustained conscious concentration. The results are quite modest as the technique is poorly developed and uneconomical. The notion of movement and motor sensations are vague, dull, incomplete, sometimes even wrong and not in harmony with the dynamic and temporal components of then optimal movement. A beginner is unable to distinguish between essential and less essential elements and phases of movement. As a rule, the initial notion is formed on the basis of the instructor's demonstration, a photo or a video recording. The so-called external sensory signal system (sight) engages and provides optical information. During this phase of motor learning, verbal information (the instructor's explanation) is also important in addition to optical information, although it has to be clear, specific and comprehensible. A beginner builds his basic notion of movement from visual and verbal information and thus creates the foundations for the execution of movement. When a beginner starts executing a movement, his central nervous system engages the motor memory which stores specific motor programmes – motor foreknowledge (Harre, 1982; Piek, 1998). In the process of learning more demanding motor tasks (tennis, skiing, golf, gymnastics) these programmes are not very frequent in motor memory; therefore, one must not be disappointed if one's first attempts are not successful. Of course, there are great differences between beginners, due to differences in the level of their motor foreknowledge and experience, motor abilities, mental concentration, motivation and endeavours.
