The aim of the study was to examine the coach-athlete relationship by analyzing the determinants of the quality of that relationship, the components emerged from previous constraints and the outcomes of the relationship. Weaccomplished a qualitative study using semistructured in-depth interviews with a total of 4 dyads (2 coaches and 4 players)selected deliberately. The data obtained suggested that the coach-athlete relationship in basketball is organized into threelayers: a) relationship antecedent variables (coach’s and athlete’s behaviour and values wanted), b) components(behaviours, feelings, cognitions, improvement and maintenance strategies, and management of differences) and c) the consequences or outcomes (the coach and the player). In conclusion, we found that the different antecedents determine the components of the relationship, generating, in the case of positive relationships, satisfaction, wellbeing andperformance, representing a personal and professional growth in both members of the dyad.
