A., et al. ( 2012) undertook a study with the title of "Development of Indicators of the National Judo Coaches Selection: Athletes and Coaches` Perspectives".These indicators included communicational, psychological, motivational, personality-moral, supportive-feedback, goal setting, experimental-technique, efficacy, leadership and management and performance assessment indicators.Data analysis results showed that there were no significant differences among statistical samples regarding Coaches' Selection indicators (p> 0.05).Also there were different priorities about Coaches' Selection indicators in samples (p <0.05) [29].
It is pertinent to note that the above reviews have also brought to the notice of the researcher about the importance of each criterion which has been selected by him in the present study.Hence, the reviews which the researcher has come across are not only justifying the appropriateness of the research problem under taken but also provided necessary further directions in completing study.Thus, considering the literature review, the researcher decided to do the study with the following research problem "Developing Criteria for Selecting Free Style Wrestling coaches at International Level".

Materials and Methods

As it is seen in Table3, there was no significant difference among coaches and wrestlers on significance level of 8 main criteria for selecting wrestling national freestyle coaches (df=4, P>0.05).In other words, all samples agreed on the level of importance of each criterion.

Discussion
As it was observed coaches and wrestlers consider the following items as the criteria for selection of the coach of wrestling national team including: 1) Personality characteristics, 2) Motivational Characteristics, 3) Scientific Characteristics, 4) Management skills, 5) Sport Characteristics, 6) Coaching Experience, 7) Communication Skills, 8) Individual characteristics.Moreover, with regards to Friedman test results, there is significant difference among coaches and wrestlers' viewpoints to determine the priorities of eight major criteria for selecting wrestling national freestyle coaches.In general, all samples had similar beliefs about the criteria importance for selecting wrestling national freestyle coaches, but they had some differences in the order of importance of the dimensions.The most prioritized factor in choosing a coach was "Personality characteristics".It was considered as a very important criterion, so wrestling federations should pay a considerable attention to this dimension.Some of researchers believe that personality characteristics are significant aspect required for hiring coaches [4,12,25,15,27,29,3,18,31] The least prioritized factor was "Individual characteristics".Thus, it plays little role in selection process of national coaches according to all subjects' viewpoints so it can be ignored.Such a finding correlates with the results of studies by [13,26,21,21]."Motivational characteristics" was considered as important criteria.As noted by [9], psychology in coaching plays an effective role in the coach's success and the athlete's functional development as well as motivational and communicational skills.All samples showed a strong similarity in "Scientific characteristics".They believed that this criterion was important.More coaching courses should be offered and publicized to current coaches so they can obtain updated information and professional knowledge to perform their coaching duties."Management skills" was considered as relatively important criterion.The results of the current study are also quite similar to the findings of Dahalkvist A. and Svensson M (2001) which found type of leadership and appropriate behavior are more important in coaching process."Sport characteristics" and "Coaching experience" were other criteria which were considered as relatively important factors.This criterion was also considered by FIFA (2012) and AFC (2011) in their coaching books and noted that a coach should be equipped with technical and tactical skills [19]."Communication skill" was put in seventh priority.In other words, it was considered as a less important factor.Some of researchers referred to this criterion [9, 14, 28, 24 and 17].These criteria and their subthemes each represent the thoughts of many of the finest coaches and wrestlers in freestyle wrestling, so developing strengths within each of these areas will assist a coach greatly in becoming an effective coach now and in the future.

Conclusion
With respect to the present study results it seems that international level wrestling coaches should have multidimensional skills such as psychological skills, unique personality, management skills as well as scientific adequacy that render determining effect on sport performance; thus sport authorities specially Wresting Federation should have specific attention to these important issues in selection international level coaches.
