Starting from the behavioral and constructivist principles of teaching and coaching and motivation of young athletes in the context of self-determination theory, this paper deals with the relationship between the expression of different types of motivation of young footballers and the preferred coaching styles of their coaches. A study was conducted on a sample of N = 132 young football players and N = 12 coaches in one large sports football club. Questionnaires and self-assessment scales were applied in sub-samples of players and coaches collecting data on age, length of coaching, length of work experience of coaches, type of coaching education completed, daily and weekly time engagement in coaching, and preferred coaching styles. In addition to general information, players completed an adapted version of the Behavioral Regulation Questionnaire in Sport, which examined the motivation to train in the context of self-determination theory. Participation in the study was voluntary for both players and coaches, with the written consent of parents obtained with the consent of the club manager for all minor participants. The results of the research showed a high level of intrinsic motivation for young players, but also indicated the importance of coaching styles of the first coach for player motivation, especially intrinsic. Specifically, the results confirmed the significant contribution of fostering autonomy and commitment by the first coach in the level of intrinsic motivation of football players. The results of the research were interpreted in the context of the initial theoretical framework, the limitations of the conducted research were highlighted, and the implications of the results were highlighted in terms of the importance of educating the stakeholders of the training process for the benefit of young players.
