Background: Education is a social process in which human beings reach social competence and individual growth. An institution that does this process is called the school. Among schools, primary schools are the most important environment for socialization and education of children, so physical education programs at this stage can provide conditions for the development of motor literacy and thus a healthy and active lifestyle. While refreshing the school yard and stimulating and encouraging the students' visual sense to engage in sports, the dynamic yard design provides a suitable ground for children to play spontaneously.Aim: This study aimed to evaluate the performance of the dynamic yard design on the physical, mental and academic performance of elementary school students.Materials and Methods: This research has been done by the library method to review related articles, take notes and infer from them.Results: The results of the research indicate that between the implementation of the dynamic yard plan and the variables of physical activity, vitality, reduction of behavioral incompatibilities, academic performance, and physical self-concept (athletic fitness, fat burning, physical appearance, flexibility, health, and self-esteem), there is a positive and significant relationship.Conclusion: Enriching the schoolyard by drawing play shapes and purposeful plans and encouraging students to do physical activities in their spare time can positively affect behavioral patterns, enthusiasm, learning, institutionalizing exercise at an early age, and developing basic skills and have public sports.

The purpose of this research was to identify strategic positioning of sports diplomacy capacities for sustainable development. The research population included professional athletes and coaches; who had experience working at international sports levels. The sample was selected via availability methods (146 individuals). Data collection was conducted through a researcher-made questionnaire. Data analysis was performed using SWOT matrix. Five professors confirmed the validity of the questionnaire, and its reliability was determined by Cronbach's alpha value of 0.89, indicating the high reliability. The results revealed that the strategic position of sports diplomacy capacities for sustainable development is in the WT quadrant, indicating that the most appropriate strategies that can be applied are defensive ones. Accordingly, respective planners and decision-makers in sports, especially policy-makers, should consider appropriate strategies to improve Iranian sports diplomacy capacities, leading to a more sustainable development.

Background: Dynamic knee valgus (DKV) is due to the weakness of the thigh abductor muscles and the vastus medialis muscle, which increases the internal rotation of the thigh and increases the possibility of anterior cruciate ligament (ACL) injury. The amount of DKV in women is higher than men, which is one of the reasons for the possibility of more injury in women. Aim: The aim of the present study was the effect of acute soccer functional fatigue on knee and trunk kinematic factors in female soccer players with and without DKV during single leg landing. Materials and Methods: The present study is quasi-experimental research conducted on 28 female soccer players who were selected using purposeful and convenience sampling. They were classified into two groups with and without DKV. The subjects performed a single leg soccer landing, and the kinematic changes of the participants' trunk and knees were recorded through high-speed video cameras (SONY camera) in two sagittal and frontal planes and analyzed by Kinovea software. The data were analyzed in SPSS-26 software using a mixed ANOVA statistical test.Results The results revealed a significant interaction effect between fatigue conditions and groups on knee and trunk joint angles in frontal plane in the initial contact with the ground in single leg landing. The results showed that fatigue significantly reduced knee flexion and increased knee valgus and trunk lateral flexion increased significantly after fatigue. Conclusion: The results indicated the acute effect of fatigue on knee and trunk kinematics of female soccer players with DKV. Therefore, by increasing the amount of knee and trunk flexion and correcting the landing technique, the possibility of ACL injury in fatigue can be reduced.

The aim of this study is to investigate the evolution of sport tourism research and identify research gaps in the field. This descriptive-analytical research utilizes a bibliography and illustration method to achieve these goals. A total of 644 articles were extracted from the Web of Science database, and their bibliometric data were analyzed using VOS viewer software. The findings reveal the trend of publishing articles and citing them in recent years, while also outline the most cited articles, researchers, journals, and universities. Additionally, the primary country in the collaboration network was identified. Keyword co-occurrence analysis indicates that the majority of research in this field pertains to sport events and their management. The results also underscore a limited focus on the approach of service dominant logic and its derived concepts. Additional areas for future research include examining tourists' behavior as customers throughout all travel stages, investigating the impact of technology on sports tourism, and exploring tourists' behaviors.

Background: Identifying the practice conditions that optimize the learning of motor skills is one of the main objectives in the field of human motor learning research.Aim: Present study aimed to explore the effect of success criteria in low-error practice conditions on motor learning, self-efficacy, and mood states among female students.Materials and Methods: This practical quasi-experimental study was conducted in a field setting. The participants were 30 female students from Yazd University, selected through convenience sampling. After they completed the consent form, the selected participants were randomly divided into three groups: low-error practice with a large target (n= 10), low-error practice with a small target (n= 10), and a low-error control group (n= 10). Then, mixed ANOVA was applied in order to test the hypotheses and data analysis was conducted using SPSS version 23, with a significance level set at P < 0.05.Results: The findings indicate that both the large (P=0.003) and small (P=0.001) target groups significantly outperformed the control group (P=0 .033) regarding the difference in performance accuracy. Moreover, In the small target group, a significant difference was observed only in the happiness subscale considering mood states (P=0.001), while in the large target group, significant differences were found in the tension (P=0 .003), depression (P=0.001), and fatigue subscales (P= 0.001). Regarding self-efficacy, significant differences were observed in the power dimension in both the large (P=0 .001) and small target groups (P=0.003)Conclusion: The use of success criteria in low-error practice methods is beneficial, and it is recommended to adopt this approach to improve accuracy and stability in practice sessions.
