The research method was descriptive-correlation. The statistical population included all active futsal coaches (men and women) in Khuzestan province, and sampling was also selected using the total number method (255). To collect the data, two standard questionnaires of management skills, Sedaghatnia (2016) and Feltz et al. efficiency (1999) were used. The validity of the questionnaires was confirmed by 9 sports management experts. The reliability of the research questionnaires was also obtained based on Cronbach's alpha (0.93, 0.88). Independent t-test and structural equation method were used to analyze the data. Data analysis was done using SPSS and smartPLS software. The findings showed that management skills (with a coefficient of 0.72 and a significance level of less than 0.001) have a positive and significant effect on efficiency. Also, the technical and human skills of female coaches were significantly higher than male coaches. But there was no significant difference between the cognitive skills of male and female coaches. The efficiency of female coaches was significantly higher than that of male coaches. Due to the fact that human skills had a more significant role in the efficiency of trainers than other skills, it is suggested that these skills should be given more attention in coaching and retraining course
