Background. An adolescent’s level of motor competence is important to assess as can impact on a range of daily functions and participation in physical activities. Formal assessments of motor competence can be time consuming and costly. One alternative is to use self-report questionnaires to screen for level of motor competence. Aim: This study examines the validity and reliability of the Persian version of the Adolescent Motor Competence Questionnaire (AMCQ) and differences between adolescent boys and girls. Method: Three evaluative stages were completed to translate the items into Persian, which included back translations by 4 native English and Persian speakers and 10 expert reviews. A total of 470 adolescents aged 12-18 years old (mean age 14.22 ± 1.64) from the Ray schools district completed the 26-item AMCQ. A subsample of 30 adolescents completed the AMCQ after 1 week for retest. Results: The content validity index (CVI=0.98) was strong. The results of exploratory factor analysis identified 4 factors and the results of the confirmatory factor analysis showed that items with a suitable factor load (0.95-0.65) on the four factors. The results revealed the AMCQ had high internal consistency (0.940), and acceptable test-retest reliability (r=0.885). When considering gender, boys had higher AMCQ scores compared to girls. The boy’s scores were related to the factors of ‘participating in physical activity and sport’ and ‘peer comparisons’. Conclusion. The results of this study show that the Persian version of AMCQ can be used as a valid tool to assess Iranian adolescence motor competence.

Psychological skill is one of the most important factors that influence athlete’s performance so the aim of this study was to examine effectiveness of Psychological skills training on Quantitative and qualitative performance of adolescence. The statistical population included adolescence swimmers of karaj swimming clubs in karaj city. 30 adolescence swimmers were selected among karaj swimming clubs using available sampling method, and were randomly assigned into the experimental and control groups. A semi experimental with pre-test and post-test assessments was used. Beside physical training, experimental group received 22 sessions Psychological skills through 3 sessions weekly that every sessions took one hour but control group didn’t received any intervention, all the participants assessed by Stopwatch and Checklist for 50-m front crawl techniques (free-running) in two steps of pre-test and post-test. Data were analyzed by combinatory variance analysis model. Findings revealed that the Psychological skills training significantly improved Quantitative performance in the experimental group (P
