[The effectiveness of interaction of volunteer coaches in training].

This study describes teaching and learning processes during a series of soccer training sessions. The predetermined course content formed the initial practicum for volunteer coaches who were in the first stage of their training. In general, the players demonstrated patterns of motor behaviour favourable to their motor learning. The coaches adopted most of the effective behaviors that had been recommended during the theoretical portion of their preparation. These observations tend to indicate the usefulness of having volunteer coaches participate in a practicum as part of their preparation, in order to improve the effectiveness of their subsequent instruction. Such instruction is likely to be even more effective if the practicum is based on training sessions of predetermined content.
