Volunteers are valuable resources for sports organizations. Most of the sports organizations need to identify and employ the volunteers simultaneously in order to continue their activities. The present study made an effort to identify the requirements and functions of ambidextrous management of sports volunteers. Considering this aim, the meta-synthesis research method was used to carry out the study. More specifically, based on the process of the meta-synthesis research method, at the first stage, 312 papers were identified by searching the relevant databases. At the second phase, 55 papers were selected by screening the identified papers. Finally, the model of the study was developed by analyzing the selected papers. The model involved five ambidextrous requirement categories including the managerial, organizational, physical, strategic values, and motivational categories. Moreover, it comprised three ambidextrous function categories including empowering measures, opportunity-creating measures, and motivating measures categories. The sports managers can focus on the ambidextrous management requirements and the ambidextrous management functions including the empowering measures, opportunity-creating measures, and motivating measures in order to use the ambidextrous sports voltmeter management system and to exploit these human resources to achieve the goals of their organizations.

The purpose of the current research was to investigate and prioritize the promoting and inhibiting factors in the development of women's professional basketball in Khorasan Razavi, Iran. This is a mixed study conducted with an exploratory-analytical approach. In the qualitative part of the research, the interviewees included sports management professors, prominent basketball pioneers in Khorasan Razavi province, professional female basketball players, as well basketball boards’ managers and representatives. In the quantitative phase, the statistical population included professional female basketball players, coaches, and basketball pioneers in Khorasan Razavi. In general, 8 interviews and 134 questionnaires were collected in the research process. The qualitative data was analyzed through the content analysis method while the quantitative data analysis process was completed by using SPSS software (v. 22) and exploratory factor analysis, as well as Friedman's ranking tests. The findings of the research revealed that out of 48 items obtained as effective factors on the development of women's professional basketball in Khorasan Razavi province, 25 items were considered as promoting factors and 23 items were found as inhibiting factors. Also, based on the results of the exploratory factor analysis test, 6 promoting factors ("socio-cultural factors", "technical level", "basic factors", "expert human resources", "competition and event", and "scientific indicators") and 5 inhibiting factors ("financial issues", "motivational supportive factors", "facilities factor", "club ownership" and "management perspective”) were identified.

Background: Observational learning is an effective pedagogical approach that can be used as a method to improve motor skill acquisition and also a useful instrument to promote psychological variables such as self-efficacy by emphasizing the motivational aspect. Although, little research is known about the model type and the observation conditions which will optimize learning. Aim: This study aimed to clarify the effect of using a combination of ideal model-observation and self-observation on self-efficacy and learning the forehand service of table tennis. Materials and Methods: Forty females were assigned to one of four experimental groups. All groups received the same instructions concerning how to perform the task, filled out a self-efficacy questionnaire, and then performed 10 pre-test trials. The acquisition phase included six sessions. The retention test was done 72 hours after the last acquisition session. Mixed ANOVA with repeated measures and Bonferroni post hoc tests were conducted, and one-way ANOVA was used to determine group significant differences. Results: The results indicated that observing the combination of skilled and learning models led to the highest self-efficacy for learning, compare with other experimental models. Also, significant learning of the task was shown in the acquisition phase in which the performance of all three experimental groups was clearly superior to the control group. Although in this phase there was no significant difference between the performances of two groups of combined skilled-learning and skilled. The results of the delayed retention test indicated that the performance scores of the combined skilled-learning group were significantly higher than the other three groups. Also, in this phase, the difference between the combined skilled self-observation and control or skilled groups was not significant. Conclusion: Demonstrating a skilled model is the most popular type of observational learning among the instructors and physical education teachers, it is suggested that adding a learning model to that leads to better performance and enhancing the self-efficacy.
