Abstract Taekwondo athletes experience a lot of pressure during the competition, because they must attack and defend at the same time, In addition, before the competition, the stress of the taekwondo athletes increases and lose weight quickly, In this context, the maintenance of desirable psychological states and success in Taekwondo requires a set of specific psychological factors, such as positive perfectionism and psychological skills. Therefore the aim of this research was to survey the relationship between Sport perfectionism and mental skills in Taekwondo Athletes. Present study research method was descriptive – correlational, Statistic population was included all of from Iranian Taekwondo athletes participated in country championship competition. Samples were 110 males with average age of (23/60 ± 5/84) selected based on random sampling, and completed the Scales of perfectionism and mental skills. The data was analyzed by Pearson correlation and multiple regression (inward method) tests. The results of Pearson correlation revealed that positive perfectionism was positively associated with mental skills of foundation, psychosomatic and cognition, and Negative perfectionism had the negative correlation with these mental skills (p < 0/01). Regression analysis showed that positive and negative perfectionism dimensions predict 40 percent of total mental skills variance (p < 0/05). According to the findings, it seems that dimensions of perfectionism have an important role in selecting mental skills and the level of skills which every Taekwondo Athletes uses is correlated with these dimensions.

Abstract The aim of the present study was to determine the validity and reliability of the Movement Assessment Battery for Children Test (M-ABC Test) for 6-year-old children of Isfahan city.  306 children participated in the study. Inter-rater reliability of the M-ABC test was estimated using two trained observers with 50 children. Test–retest reliability was assessed using 30 children with a one-week interval. To determine construct validity of this test, explanatory and confirmatory factors analyses were used. Agreement between testers was great with a mean intra-class correlation coefficient of 0.98. The mean intra-class correlation coefficient of 0.77 was obtained for test–retest reliability. Three-factor structure of M-ABC test and proper assignment of skills to manual dexterity, ball skill and balance factors were supported for this population. The According to these results, M-ABC test can be applied to assess fundamental skills of 6-year-old children of Isfahan city.

Abstract The present study was designed to determine the effect of different levels of body mass index (BMI) on fundamental motor skills in 6-year-old children of Isfahan city. For this purpose, fundamental motor skills of 19 underweight children (grade 3 thinness) and 19 children with normal weight and 19 overweight children who were matched according to their gender and socioeconomic background were assessed using the Movement Assessment Battery for Children (M-ABC). Among 8 items of M-ABC, normal weight and overweight children differed on only one-leg balance with preferred leg and normal weight and underweight children differed on only walking heels raised item. However, the total motor impairment score which was calculated by the summation of the 8 item scores was higher in underweight and overweight children than their normal weight peers.
