The validity and reliability of the questionnaires was measured and modified.Data were analyzed using multiple regression and Structural Equation Models (SEM) in significance level of P<0/05. The finding showed autonomy-supportive behaviors had significant positive correlation with intrinsic motivation, introjected regulation and indentified regulation. However, autonomy-supportive negative correlation amotivation.In addition, intrinsic motivation, introjected regulation and indentified regulation had significant positive correlation with sport commitment players.Multiple regression showed autonomy-supportive coaches was predictor factor for the intrinsic motivation, extrinsic motivation and sport commitment players.path analysis results offered support for the proposed model. Total mediation was supported in the case of intrinsic motivation, introjected regulation and indentified regulation in the relationship between autonomy-supportive coaches and sport commitment players. The findings underline the importance of perceived autonomy-supportive coaches in motivation and sport commitment players. The results provide support Self-determination Theory in elite players

The purpose of current study was to consider a course of doing psychological skills training (PST) program on chosen mental skills and the performance of teenager female taekwondo athletes with mean age 16 years of Iranian national team in 2009. The current study is in tentative type and pre and post test design with control group. To do this 22 people (female) among invited people to the camp of taekwondo national team in teenager level for participation in Asian competition of Kish were randomized and then were separated into two groups of control (10) and experimental(12). Then both of them completed the OMSAT-3 questionnaires in pre-test stage, so that to be evaluated from the view of mental skills and making check list for performance evaluation. According to gained results of questionnaires in pre-test stage and based on subjects weakness in skills of reaction to stress, fear controlling and concentration, an exercise package of purposing, goal setting, relaxation and imagery was used as PST program. After 4 months PST program of both groups was performed. Collected data was considered by independent statistical t-test. The results of this study showed that there is a significant difference between control and experimental groups in skills of reaction to stress and concentration after doing a course of PST program (P < 0.05). But there was no significant difference between these two groups in skill of fear controlling (P > 0.05). At last the results showed that there is a significant difference between control and experimental groups in performance after doing a course of PST program (P < 0.05).

Perceived motivational climate in sport questionnaire (PMCSQ) with 21 questions and athletes' satisfaction questionnaire (ASQ) with 14 questions were used as a data. The validity of Questionnaires confirmed by 6 specialists. The reliability coefficient of the questionnaires in a guide study was estimated respectively 0/82 and 0/89. Data were analyzed by using the ANOVA with repeated measures, Bonferroni post hoc test, depended t-test, and Pearson's correlation coefficient at p&le 0/05. The results showed that motivational mastery climate have higher average than motivational mastery climate. Also, there were significant differences between four aspects of the athletes' satisfaction, and players were more satisfied with coach treatment in comparison to other aspects.

The aim of this study was to examine the effects of attentional focus on accuracy,
effectiveness, and perception of the performance in volleyball jump serve of
professional players. 12 professional volleyball players completed a 4 blocks of 8
trail (4 for accuracy, and 4 for effectiveness) of jump serve in four experimental
conditions (Non-Instruction, Internal focus on hand movement, Near external
focus on ball, and Far external focus on target zone or player). The data of
accuracy, effectiveness, and self-perception of the performance was acquired by
pointed target areas, analyzing volleyball serve effectiveness method, and selfrated
manipulative check, respectively. Results of ANOVA with repeated
measures showed that accuracy scores, effectiveness, and self-perception of the
performance in far external condition was better than near external and internal
conditions. In addition, the significant differences between non-instructional and
far external conditions were observed only in self-perception of the performance.
On the whole, these results confirmed recent findings regarding the detrimental
effects of internal focus of attention and the facilitative effects of external focus of
attention on skilled performance, especially far external focus.

The purpose of present study was to investigate predictions of challenge point theory (guadagnoli and lee, 2004) through comparing two group of challenging and nonchallenging games in developing manipulative fundamental movement skills. Thirty 4 to 6 years old child were selected from one of the kindergartens of Tehran and were grouped according to pretest scores. The games were used were designed for developing manipulative skills in both groups, however the task difficulty of these games was increased in challenging group while in nonchallenging group it was kept constant. The intervention was 8 weeks, 2 session for each week and 42 minutes for each session. Children's manipulative skills were assessed using Test of Gross Motor Development – second version in the beginning and the end of the intervention. The results of multivariate analysis of variance showed  that improvement groups in total score of manipulative skills and all subscales exept that catching wasn't significant. In total, if the challenge point theories predictions on developing of manipulative skills of healthy children failed to be proved but better improvement of challenging group in catching shows that this method is more effective in developing complex skills.

The aim of this study was to determine the effect of secondary task relevant and non-relevant to the free throw basketball skill on the free throw accuracy of basketball skilled players in choking under pressure. Twenty right-handed female players (aged 18-30) each with at least three years of experience in basketball took part study after completing the Sport Competition Anxiety Test (SCAT), Annett Handedness Questionnaire (AHQ) and measuring their anthropometric characteristics. The study included two testing sessions with an interval of 2 days. In the first and second session (no-pressure and high pressure, respectively) participants warmed up and performed 10 free throws in three conditions: 1) free throw, 2) free throw with relevant secondary task, 3) free throw with non-relevant secondary task. Results showed that the secondary relevant and non-relevant tasks to free throw have effects on accuracy in no-pressure (P=0.012, P=0.001) and high pressure (P=0.001, P=0.018) conditions. Also, there was significant differences between relevant and non-relevant tasks effects on accuracy in high pressure situation (P=0.001).
Overall, it may be used the secondary relevant and non-relevant tasks in choking under pressure situations for reduction of pressure imposed on athletes. Also, properly designed secondary tasks for free throw may be used to increase the accuracy of skilled participants under the pressure situations.
