With this study, we intend to diagnose the quality of athletes' experiences in Portugal, as well as the characteristics of the pedagogical intervention of the sports coach and parents.

In this sense, we intend to answer the following research questions:

1. What are the perceptions of young athletes about the quality of their experiences in training sport and the relationship established with their parents/coach/club?
2. What are parents' perceptions about the quality of experiences lived by their children and the relationship established with athletes/coach/club?
3. What are the coaches’ perceptions regarding the quality of experiences lived by young athletes and the relationship established with athletes/parents/club

This study aims to analyze, in an in-depth and comprehensive way, the state of training sport in Portugal, allowing the identification of relevant practical implications for policy change.
