The purpose of this research was to study the effect of 12-week physical activity on resiliency, productivity and reducing staff absence based on public health of the female staff of Islamic Azad University. In this paper, we used the pretest-posttest quasi-experimental study designs The method of this research was semi-experimental and carried out having pre-test and post-test with pre-testpost-test design with two control and experimental groups. The population of the research was consisted of 94 individuals among whom, the female staff of the university out of 94 academic staff, 48 persons were randomly selected and assigned to either of the control or experimental groups each containing 24 subjects. The tools for gathering data were the resiliency inventory of Connor and Davidson (2003) with Cronbach's alpha of r=0.90 and validity of r=0.84. The other questionnaire used for the productivity of workplace was and productivity inventory of Hang (2008), its reliability using reliability was r=0.71 and its validity was r=0.60 were used in order to measure the study variables. To test hypotheses independent t test and Mann Whitney test were used at α=0.05 to analyze the data. The results showed indicated that 12-week physical activity had significant effect on resiliency and productivity of the staff subjects. But the 12-week physical activity has not had a significant while the positive effect on reducing staff absence. It is recommended that managers stimulate regular physical exercise to all staff in organizations and to establish practical plans to provide physical activities, especially female staff whom suffering from special restrictions, can take advantages of this plan (productivity and resiliency).

Successful performance in many sports such as roller skates, often require recognition and appropriate agility, balance and self-confi dence to various situation. To achieve a high level of profi ciency and self-confi dence, good core stability can help maximize roller skates performance. The purpose of this study was to determine the effects of core stabilization exercises on selected motor profi ciency indexes (agility and dynamic balance) and self-confi dence in girl roller skaters. This is an experimental study. The population consists of the girls roller skaters between 14-16 years of age. Based on Solomon four group design, a total of 40 girl athletes were randomly assigned into four experiment and control groups. During 8 weeks each group received its own treatment and then all groups participated in a posttest. The experimental groups received experimental treatment during the experiment. The comparison of posttests indicated that experimental treatment (core stability training) has not signifi cant effect on the balance, agility and self-confi dence of girl roller skaters. It is, therefore, could be concluded that more intensity and duration of exercises are needed if the experimental treatment effect to increase the self-confi dence, balance and agility of participants in the study.

Background. Organizations are always trying to retain and empower their talented employees so that they can perform well. However, they are still afraid of losing their human capital. Objectives. The purpose of this study was to design a job retention model for swimming coaches based on talent management and the quality of working life. Methods. It was an applied descriptive-survey study. The statistical population included the swimming coaches of East Azarbaijan province (773 persons). According to the Cochran formula, 285 people were selected by a stratifiedproportional random sampling method. Data collection tools included Katajar Employees' Talent Management Questionnaire (2012), Stephen et al.'s (2015) Quality of Working Life Questionnaire and a Researcher-made Job Retention Questionnaire. Results. The results showed the direct and significant effect of talent management and quality of working life on job retention. The mediator role of quality of working life also had a mediating effect on the relationship between talent management and job retention. Finally, the proposed model has a good fit. Conclusion.

Introduction: Regular physical activity is considered as the first priority in healthy lifestyle. Due to the importance and role of mobility and physical activity in women's lives, the main goal of this research was to design a model for attracting females to fitness clubs by  emphasizing on the health promotion behaviors.  Methods: In this research, a combination of qualitative and quantitative methods was applied. The statistical population included all female clients of fitness clubs, who exercised in these centers for more than six previous months in Yazd. For sampling, a combination of cluster and relative methods was used. The research data were analyzed using the structural equation model through the Amos software version 23. Results: Based on the findings of the exploratory factor analysis, three effective factors of environmental (design, facilities, and health), social (administrators, family), and services (planning, advertising, cost) were identified in attracting female clients to the fitness clubs in Yazd province. The results of the model's fitness indices showed a good fitness for the proposed model. Conclusion: The findings suggest the physical fitness clubs to have more effective plans. The club managers are recommended to consider expectations of their clients, especially women and mothers to  attract more customers to their clubs.
