Abstract
In this study, the effectiveness of student-centered and coach-centered coaching styles on sport self-efficacy and athletic performance of female gymnasts was studied. The research method was quasi-experimental and a pre-test-post-test design was used. The statistical population was female gymnasts aged 11-14 in Tehran. The sampling method is one-stage clusters and the research sample is 40 female gymnasts who were selected based on Cochran's formula. Variable assessment tools included Sport Self-Efficacy Questionnaire (Sahraeian et al 2016) and a researcher-made sports performance questionnaire. After the pre-test, the groups performed the athlete-centered and coach-centered training protocol separately for two months and two days a week in one-and-a-half-hour sessions. Covariance analysis was used to test the hypotheses. Findings in the pre-test stage showed that sport self-efficacy and athletic performance of female gymnasts in the student-centered group were significantly higher than the coach-centered group (P <0.05). It is concluded that student-centered coaching style is more effective in increasing Gymnasts' sports self-efficacy and athletic performance compared to coach-centered, and coaches are suggested to pay special attention to student-centered exercises in the gymnastics girls' training program.
