In the sporting contexts, self-concept has been pointed out as a fundamental psychological attribute for the performance of coaches and athletes, focusing on the control of emotions and expectations of success or failure. The impact of self-concept on the leadership style of Brazilian coaches was investigated among coaches and technical auxiliaries/physical trainers (n=40) of teams participants of Futsal National League 2013 and the Brazilian national team. The instruments were the Factorial Scale of Self-Concept and Leadership in Sport Scale. Data were analyzed through Repeated Measures Anova, Spearman correlation, Simple and Multiple Regression (p<0.05). Results showed positive and significant correlations (p<0.05) between the Training-Instruction and Reinforcement styles with most of the self-concept dimensions. Social Support correlated positively with Social Responsiveness (r=0.34) and Autocratic Style correlated negatively with Social Attitude (r=-0.38). There was a moderate effect (β>0.20) of Social Attitude toward Autocratic, Safety toward Training-Instruction and Self-Control toward Training-Instruction and Reinforcement styles. It was concluded that Brazilian futsal coaches and physical trainers perform a leadership oriented towards performance and positive reinforcement, with self-concept associated to the adoption of these styles.
