Purpose: In this study, it was aimed to scrutinize the relationship between the understanding of fair play and self-confidence of oil wrestlers.Material:The research group of the study comprised 258 oil wrestlers. In the study, the demographic information survey prepared by the researchers, the Multidimensional Sportsmanship Orientation Scale developed by Vallerand et al. (1997), the validity and reliability of the Turkish version of which was conducted by Balçıkanlı, and the Self-Confidence Scale developed by Akın (2007) to evaluate their self-confidence were used. Participants responded to the questions of the multidimensional sportsmanship scale and self-confidence scale using a survey method in the digital environment. It was decided whether the data met the prerequisites of the parametric tests by poring over the Skewness and Kurtosis (normal distribution condition of the data) values and the results of the Levene (equality of variances) test. One-Way Analysis of Variance was used to determine the differences of the variables.Results:As a result of the research, no significant difference in the self-confidence levels of the participants according to their Sports year, mother and father's profession, and mother and father's educational status (p>0,05) was observed, while significant differences were found in their sportsmanship orientations (p<0,05). Within the scope of the relational model, it was determined that there was a moderate positive relationship between four sub-dimensions of the sportsmanship orientation scale (compliance with social norms, respect for rules and management, commitment to responsibilities in sports, respect for the opponent) and both intrinsic and extrinsic self-confidence. Conclusions: In conclusion, it can be said that as the value given to sportsmanship orientations increases, self-confidence will also increase.
