Methodology: This is descriptive and correlational study in which 30 women from national karate team (adults and younger adults) formed the whole statistical population Completed the Martens Competitive state and competitive trait anxiety questionnaire and also completed the Dunn and colleagues’Sports perfectionism questionnaire. The findings of the research were analyzed using descriptive statistics (mean & standard deviation), Pearson correlation coefficient and Stepwise regression analyses. Results: Results from Pearson correlation coefficient indicated negative correlation between perfectionism sport and self-confidence, and a positive correlation with trait anxiety. Stepwise regression analysis results indicated that perfectionism is generally the strongest predictor of trait anxiety. Also, perceived pressure from the coach predictor of cognitive anxiety and self-confidence, and concern over mistakes and personal standards are predictors of somatic anxiety. Conclusions: moderating Perfectionism helps the athlete to be less affected by competitive anxiety, increases her self-confidence and thus, the probability of success increases.

The current research aims to compare the effect of basic gymnastic exercises in environments with different colors, on static and dynamic balance. Participants were 40 female students ranging in age from 8 to 10 years, who were classified into three groups: "exercise in the environment with warm colors", "exercise in the environment with cool colors" and "exercise in the environment with compound colors". A pre-test of balance was given to each group in its colored environment. Static and dynamic balance were assessed using the balance subscale of bruininks-oseretsky test of motor proficiency. Then the groups have performed gymnastic exercises in colored environments for 24 sessions, and after 8 weeks, they took the post-test in the same environment. The transfer test was performed in the environment with a neutral color, 48 hours after the post-test. Data were analyzed using one-way ANOVA and ANCOVA tests. The findings showed that the color of the environment had had no effects on the learning and retention of static and dynamic balance.it seems that, the color of learning environment related to type of motor skill.
