From the point of view of practical purpose, this research was qualitative and quantitative in terms of data type, and in terms of data analysis method it was exploratory and in terms of time perspective and field data collection method. The statistical population included male students between the ages of 16 and 18 who had withdrawn from sports for at least two years. In the qualitative and interview section, the theoretical sampling method was used in a targeted manner until theoretical saturation was reached, which was finally achieved with 11 interviews. In the interview phase, the data was analyzed using the method of structural interpretation of the text, and in the stratification phase, the stratification was done using the interpretive structural modeling method and using the latest version of Mic Mac software. The data obtained from the interviews were categorized into 33 central codes in the form of 6 selective codes. Six optional codes included lack of motivation, lack of self-confidence, lack of perseverance, non-sports environment, unmotivated coaches and economic problems. Interpretive-structural modeling showed that the non-sports environment was the most influential component and the two components of lack of motivation and lack of self-confidence were the most influential components. Considering the high impact of the non-sports environment on the students leaving sports, it is suggested to strengthen the school environment as much as possible in terms of sports attractiveness.
