Data collection tools were qualitative phase, semi-structured and open interviews with 23 professional athletes, athletic instructors, sports managers, psychologists and sports sociologists. In the qualitative research, statistical samples were selected using snowball method. Data were analyzed in qualitative phase by coding method in three stages: open, axial and selective.
