The present study was conducted with the aim of comparing and investigating the tendency to exercise, academic vitality and mental well-being in normal and elite students. The method of the current research is a descriptive-analytical one that was conducted on a sample of 60 students (30 elite students and 30 regular students) of Lorestan University in the academic year 2008-2019, who were selected by random sampling. To collect the data, the questionnaires of Zarandieh's tendency towards sports (2003), academic vitality of Dehghanizadeh and Hossein Chari (2006) and mental well-being of Keirs and Makiramo (2003) were used. The collected data were analyzed using Pearson's correlation coefficient test, multiple regression analysis by stepwise method and independent t-groups. The results of this research showed that there is a significant difference between the tendency to exercise, academic vitality and mental well-being among elite and normal students. The results of multiple regression analysis by step-by-step method also showed that the variables of sports orientation and academic vitality together predict 25% of the variance of mental well-being. According to the results of the current research, it seems necessary to provide the necessary ground for improving and promoting the mental well-being of students, especially elite students, by formulating, planning and presenting a suitable policy.

The present study has evaluated the specialized scientific competitions of physical education teachers and its effect on the empowerment and behavioral intentions of teachers participating in these competitions. This research is a descriptive- correlational research that has been done by survey and field method. The population and statistical sample was equal and included all teachers participating in the 28th scientific-specialized competition of physical education teachers across the country (n=187). The instrument used is a researchermade questionnaire, the reliability of which was confirmed using Cronbach's alpha (r=0.85). Descriptive and inferential statistics were used for data analysis with the help of spss20 software. We also used structural equation modeling with AMOS16 software to check the research model. The results of Pearson's correlation coefficient showed that the highest correlation between comprehensive and complete assessment variables with test suitability (sig=0.001, r=0.78) and the weakest correlation between media coverage variables and administrative reward and support (sig=0.001, r=0.30) was observed. Finally, by using structural equation modeling, the direct effect of test fit on behavioral intentions was obtained as 0.45. Also, empowerment as an independent variable explains 0.23 of the variance of behavioral intentions. Finally, the suitability of the test explains 61% (directly and indirectly) of changes in behavioral intentions. Although the results of this research showed that specialized scientific competitions have a good fit from the point of view of the participating teachers, but the authorities should provide more suitable rewards (financial and non-financial) for more and better participation of teachers and the continuation of this participation in the following years.

The purpose of this research was to determine the relation between management styles of school principals and the level of satisfaction of physical education teachers. The method of this research is designed in terms of practical purpose, according to the descriptive definition and using practical methods. The statistical population of the research was made up of all physical education teachers of Asadabad city. The statistical sample consisted of 42 people, and due to the statistical sample being equal to the statistical population, the statistical sample was considered as a total number. The data collection tools were two questionnaires, Elmore's leadership style (2000) and Minnesota's job satisfaction questionnaire (1967), which were divided among the statistical samples. The validity of the questionnaires was confirmed by 9 sports management professors, and the internal stability and temporal stability of the questionnaires were confirmed using Cronbach's alpha coefficient. SPSS version 26 software was used for data analysis. Descriptive and inferential statistics methods were used for data analysis (frequency table, frequency percentage, Kolmogorov Smirnov test, Pearson correlation coefficient at a significance level of p ≤ 0.05, simple linear regression of multiple tests, F test). The findings of the research showed that there is a positive and significant relationship between leadership styles and internal satisfaction, leadership styles of participation and external satisfaction, and managerial styles and job satisfaction of physical education teachers. Therefore, according to the obtained results, achool administrators should give more trust and authority to teachers in doing school affairs in order to create teachers satisfaction.

Describing findings and categorizing information using descriptive statistics, determining the reliability of questionnaires using Cronbach's alpha method, examining data distribution using the Kolmogorov-Smirnov test and path analysis of relationships between variables using structural equation modeling (PLS3 software). The findings showed that customer knowledge management has a positive and significant effect on co-production in sports clubs with a coefficient of 0.83. Also, customerknowledge management has a positive and significant effect on the value of use in sports clubs with a coefficient of 0.76.

The purpose of this research is to investigate the relationship between anthropometric characteristics and common injuries of students in Bojnord city. The current research is of a descriptive and correlational type, the data of which was collected in the field and quantitative measurements. The statistical population of this research was made up of all female student runners in the academic year 1401-1400, of which 60 people were selected as a sample in the disciplines of speed (30 people), semi-endurance (15 people) and endurance (15 people). In order to measure and collect information from Ismaili et al.'s questionnaire (2013), a tape measure, digital scale, caliper, goniometer, and a ruler were used. Kolmogroph-Smirnov test was used to check the distribution of data. In the meantime, according to the abnormal and normal distribution of different variables, chi-square tests and Pearson's correlation coefficient were used to check the relationship between variables. SPSS version 21 software was used for statistical analysis. (p<0.05). The results showed that there is a significant relationship between weight and plantar fasciitis and age and Achilles tendonitis in runners. On the other hand, a significant relationship was observed between thigh length and hamstring elongation. However, no significant relationship was observed between other anthropometric dimensions and runners' injuries. It can be concluded that the coaches and sports teachers should inform the running students about the anthropometric dimensions as well as the injuries that are common in the running athletes and for proper and correct training and injury prevention, they should train the students with Justify educational workshops.

Ankle injury is one of the most common musculoskeletal injuries in sports activities, which generally account for 10 to 15 percent of total injuries. Accordingly, this research is aimed at. Comparison of 8 weeks of neuromuscular and NASM exercises was performed on the ankle deepness, stomach control and range of motion of fosal. In this semi experimental and applied study, 20 fotsal were randomly divided into two groups euromuscular training (10) and NASM (10). Neuro-muscular and NASM exercises for 8 weeks and 3 sessions per week. Deepness by gonometry of both legs. Stress control including dynamic equilibrium by SEBT test to assess dynamic stance control on the upper leg and range of motion by goniometer before and after The 8- week training program for Neuromuscular and Tranand training was measured. Data were analyzed using independent t-test and independent t-test using SPSS version 22 software. The significance level was considered to be P≤0.05. The results showed that there was significant difference between the eight weeks of neuromuscular NASM exercises in the ankle deep sense (P≤0.05). Also, there was significant difference in the dynamic balance of the two groups after the intervention (P≤0.05). There was no significant difference in the strenght between the two groups after intervention (P≤0.05). Therefore, adding neuromuscular and NASM exercises to the rehab program as an affordable, safe and non-invasive method can increase stomach control, deep ankle sensation and improve the range of motion in fotsal.
