The sports practice started in childhood promotes several health benefits for the child, improving and developing the natural abilities acquired over time, as well as socialization, bonding, friendships, etc. The way this process occurs can significantly alter this child's future as well as their health. Therefore, the objective of the present study was to reflect on the importance of sports practice in childhood, its relationship with possible reasons for abandoning the practice permanently, and the impact of this in adult life. In order to carry out this research, we used the Scielo, Google academic database with theoretical scanning through the keywords: "sports initiation", "health" and "abandonment", in the search period between 1998 and 2018. The data analyzed indicate that even if a child is part of a sports team, the play should prevail, especially for those who practice a certain sport only for leisure and / or for non competitive purposes. It is up to the teacher / coach / coach to instruct each child in order to provide health gains as well as strive for a balance between recreation and competition. Frustrated sports practices in childhood can impact on a sedentary adult, since the previous experiences of the same were not positive, with that the culpabilization of this can fall on the professional. The more playful and entertaining your experience in practice, the easier your staying will be. When it comes to the children's audience, the Physical Education professionals who work in this environment, in a multiprofessional work with Sports Psychology, must take into account the taste that the child acquired with the practice of sports, creating strategies of motivation for the permanence of it in the sport . With this, sports initiation assumes a significant role of social, physiological and psychic development of the child, making sports practice more pleasurable and healthy.
