The issue of stress and job satisfaction is always one of the most important concerns of managers in organizations. On the other hand, the organization's support for the staff and the transformation of the Police complex is always at the top of the commanders' work. The purpose of this study is the effect of change management on stress and job satisfaction through the mediated organizational support of Police sports managers.

The present study is applied in terms of purpose and correlational in terms of nature and descriptive method. The statistical population consisted of approximately 95 Police sports managers, all of whom were considered as a sample by the whole number method. The measuring instruments were Perceived Organizational Support Questionnaire of Eisenberger et al. (1986), James Castiglioni Transformation Management Questionnaire (2006), Brooks et al. (2009) and Job Satisfaction Questionnaire of Ghasemzadeh et al. (2012). Convergent and divergent validity, combined reliability and Cronbach's alpha were used to analyze the data using descriptive statistics including mean and percentage, and to test the hypotheses, the structural equation approach and Spss and pls software were used.

The results showed that perceived support has a positive and significant effect on the relationship between change management and job satisfaction (indirect = 0.061, t = 2.31 and p <0.05). Also, perceived support has a negative and significant effect on the relationship between change management and job stress (indirect = -0.04.01, t = 1.75 and p <0.05). Also, a positive and significant effect was observed on the relationship between transformational management on perceived support and job satisfaction and perceived support on job satisfaction. It was also found that transformational management has a negative and significant effect on job stress and perceived support on job stress.

. The results showed that change management has an effect on stress and job satisfaction with the mediating role of organizational support of Police sports managers. Therefore, Polic sports commanders and managers should pay special attention to the role of change management and organizational support to reduce stress and increase job satisfaction.

This research was aimed atexamining effective techniques on improvement of shooting skills among students at Amin Police Sciences University.In this regard, five main techniques including, shot optimal point, containment technique, concentration and releasing of the trigger, identification and the degree to which they affect shooting skill were investigated. The current research is applied in terms of nature and methodologically, it is a semi-experimental one. The administration method is as follows: first, a pretest is given to a 32 people group and then, specified techniques will be taught to them during a month and thereafter, a posttestwill beadministered to them and the resulting findings are going to be analyzed. Tools for practices gathering data consisted of shooting score cards and all the trainings were done by the researchers and two relevant tests were also administered by three officers at the shooting field. While analyzing data, Pearson CorrelationCoefficient Test, Multiple regression, ANOVA Test, Tukey's follow-up tests as well as LSD were applied, such that these tests were performed by using SPSS software and conceptual models were designed by EQS software. . Findings indicate that from among the six techniques under study, five techniques of shot optimal point, guncontainment skill, concentration and releasing of the trigger and physical fitness have positive effects on the improvement of shooting skill, and only the constant physical technique leaves no effect on shooting skill. Of the five effective techniques, Beta coefficient level of the releasing of trigger was higher than the rest and the degree to which the technique of concentration was effective on the skill held the least effects. Also one of the most important cases in improving shooting skills is physical fitness. Results indicate that via training these techniques, one can increase student's shooting scores quite considerably in a short time interval, because the mean studentsshooting score in the pretest was 22.18 out of 100, where this score rose to 61.31 in the posttest. Also, training thesetechniques must be performed in a form combined of theoreticaland practical trainings. It is recommended that such varied manners as stringent practice, shooting simulations and combinational be used. Another main point is to observe arrangement and sequence of the techniques; since if arrangement and sequence of the quality of trainings is done in line with executiveguidelines, maxim results will be accomplished in the end.
