Little research has been carried out on the common symptoms and mental disorders in Iranian elite athletes. The purpose of this study was to identify the mental health problems in Iranian elite athletes as a retrospective study at the National Olympic Academy (NOA) of Iran. The present study is a cross-sectional and retrospective descriptive study which was conducted by evaluating the athletes' psychological documents. A total of 143 athletes (male, n= 83, female, n= 60) were analyzed from the population of elite athletes (n=240) who referred to the mental training and consulting center in the NOA during the years 2007-2021. The results showed that most athletes referred to the center to improve their performance (37.8%). Anxiety (27.3%), depression (16.8%), interpersonal problems (11.2%), impulsiveness (2.8%) post-traumatic stress (PTSD) (2.8%), sleep disturbance (1.4%) were the most common mental disorders reported by athletes. In addition, surveying the relationship between demographic characteristics and mental health issues revealed a relationship between gender and mental health problems; there was no relationship between other demographic variables with mental health problems. The results of this study illuminate the spread of common mental health problems in Iranian elite athletes over the last fourteen years. Screening and diagnosing psychological problems provide a better understanding of the application of appropriate psychological interventions and improving the mental health of elite athletes. Accordingly, future research may focus on better understanding of mental health problems reported in this study and studies them in a larger population.

The purpose of this study is to explore the effective factors on the productivity of human capital via an interpretive structural modeling (ISM) in General office of Sports and Youth in Khorasan Razavi Province. The present study is a qualitative research with an analytical nature and it is also an applied one that was conducted via interpretive structural modeling. Literature review, interviews and ISM questionnaires were used for data collection. The research population included professors and experts in sports management, managers, deputies and staff of the General office of Sports and Youth in Khorasan Razavi, of which 35 people were totally selected through purposeful sampling in three stages of this study. According to the research findings, 59 effective indicators were identified under seven major dimensions playing role in improving the productivity of human capital, which were classified into five levels. Motivational factors, organizational culture and work environment, the relationship between managers and employees along with individual factors, the quality of labor force, and finally the technology factor were identified under five levels of the model. Finally, it can be concluded that managers in sports organizations should pay special attention to the technology factor and its indicators, which have been identified as the foundation of improving employees’ productivity, which then provides the ground for exploiting other dimensions at higher levels.

The purpose of this study was to explore why and how can donors be involved in the development of student sports?. The research method was based on grounded theory approach (Strauss & Corbin method). The statistical population in the qualitative stage included 15 experts and key experts including university professors and executives of university sports who were selected by purposive sampling, and at the quantitative stage, 315 people who were active in the field of charity and student sports were studied. The results were analyzed using confirmatory factor analysis in the form of structural equations with SPSS and PLS software. 73 primary concepts were identified, which were categorized into 58 sub-categories. Compiled to collect information. According to the developed model, the existence of security for donors in investing in student sports and providing the necessary support such as granting appropriate facilities, exemptions, and tax discounts provide incentives for the private sector to participate in various sub-categories of physical education and sports. In addition, considering other barriers as well as focusing on developing strategies, could potentially lead to donor investment and participation in student sports.

The aim of this study was to develop a model for examining the mediating role of job characteristics in the relationship between structural empowerment and professional commitment of referees in female's Futsal Premier League. To collect the required data, we distributed the research questionnaires among 75 Futsal Premier League referees invited to the pre-season qualifying class in 2020, and finally we received 63 valid questionnaires. We conducted structural equation modeling, confirmatory factor analysis and path analysis for data analysis by using PLS Smart software. The findings demonstrated that structural empowerment can predict professional commitment, but the relationship between the two variables was not significant. The relationship of structural empowerment with job characteristics and professional commitment was not significant. The mediating role of job characteristics in the relationship between the two variables was not significant. The components of information sharing in structural empowerment, attachment to professional commitment and diversity of skills in job characteristics had the highest averages. Given that the lack of significance of the relationship among structural empowerment, professional commitment and job characteristics, is questionable and it should be assessed in great details.

Background: In addiction field, there is more attention on men than women, while women are more vulnerable to addiction. Because of the importance of women in the family foundation, we decided to investigate this subject. Purpose: This study aims at the effect of 8-weeks of combined training with methadone on cardiovascular inflammatory markers fibrinogen and CRP on addicted women. Method: This study accomplished as a semi-experimental research. 24 addicted women were randomly selected as samples from Zahedan Mohabbat addiction Camp that divided in two groups of methadone (N= 11) and methadone/ exercise (N= 13) by the same variables such as age, BMI, type and duration of drug withdrawal. The protocol of combined exercise was included of aerobic added to strength training; also methadone was taken according to the camp instructions, too. Blood sampling, pre and post 8 weeks exercise were directly collected from anterior veins of samples and the levels of plasma fibrinogen and CRP were measured in lab. To compares of the pre and post tests means for each group as well as both groups, paired and independent t-test via SPSS software version 24 were used, respectively. Statistical significant level was considered PResults: The results showed that CRP values in both groups decreased significantly (methadone: p <0.05, T=-2.21 and methadone/ exercise p <0.05, T=-2.63). Also, plasma fibrinogen values in both groups increased significantly (methadone: p <0.05, T=5.03 and methadone/ exercise: p <0.05, T=4.21). Also, there were no significant difference between post-test’s levels of CRP and fibrinogen between methods (P>0.05). Conclusions: It has suggested that the method of methadone/ exercise might be used as such as methadone method by the same results on plasma fibrinogen levels and CRP for withdrawal addiction women.
