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.

The purpose of this study was to develop a scale for measuring the service quality in sport scientific journals. A mixed approach was conducted to fulfill the research objectives. In qualitative phase 15 sport paper writer were interviewed and in quantitative phase, 357 sport researchers were studied through systematic random sampling. The face and content validity of the scale was confirmed by 15 experts and the final questionnaire of the scientific journals service quality was provided to 29 subjects. 26 items were ranked in five factors (accountability speed, executive structure, trustworthiness, employees and updating) based on exploratory factor analysis with orthogonal rotation. Cronbach's alpha, KMO, Bartlett Test and confirmatory factor analysis were used by SPSS and LISREL for data analysis. It is worth noting that the results of confirmatory factor analysis and Cronbach's alpha coefficient (0.91) supported the five-factor structure of JourQual scale and confirmed its validity and reliability.

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.

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.

Justice as a basic necessity of social life, plays a critical role in administration of sport teams and sport organization. The aim of the present study was to investigate the relationship between Perceived Organizational Justice in Collegiate Sport Teams and Sport Achievement Motivation. In this descriptive –correlative study, 102 student athletes (56 males, 46 females) who were selected as statistical sample from Northern Khorasan and Razavi Khorasan provinces responded to Organizational Justice Questionnaire developed by Niehoff & Moorman (1993) and sport achievement motivation Questionnaire developed by Gill et al. (1983). Conducting correlation coefficient for data analysis revealed that perceived organization justice and its subscales significantly correlated to sport achievement motivation in collegiate sport teams. Moreover, the results of the stepwise regression revealed that, among perceived organization justice subscales, interactional justice was the strongest predictor of sport achievement motivation.

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.
