The aim of this study was to comparison the effect of different core stability training on lower extremities strength among deaf children. 28 deaf students (aged: 8-14 yr) selected and randomly divided into 3 groups: dynamic core stability, static core stability and control. Training continue for 8 weeks and 3 session per each week. The protocol composed of: specific training for spinal column stability, breathing maneuver with multifidus contraction, using dynamic stability in different positions accompany by extremities movements and using swiss ball. Dynamometer device was used to measures the strength of core stabilizer muscles. Dependent t (pre and post comparison in each group) and one way Anova were used to analyze data. Level of significant was 0.05 and statistical calculations were used by SPSS (version 22). The results of this study show that dynamic and static core stability lead to significant changes in lower extremities strength (P≤0.05, t=2.2, t= 5.7, t= 4.8, t= 2.8, t= 3, t=7.4), but the differences between dynamic and static core stability training and control were not significantly (P≥0.05, f=0.74, f=1.4, f=0.13, f=0.46, f=0.18, f=0.24). It can be concluded that dynamic and static core stability training can be a benefit method to improve lower extremities strength in deaf children and this finding leads to decreasing risk and probable injuries.

The aim of the study was to assess the state of academic education in sport management in Iran. A mixed methods research approach was utilized, involving the collection of documentary data from relevant websites, followed by interviews with experts in sport management education. The participants were purposefully selected using a non-random method. The findings revealed the existence of 65 doctoral programs in sport management, with a target of attracting 266 students, as well as 261 master's programs in three tracks within sport management, aiming to draw 3554 applicants. Furthermore, there are approximately 230 faculty members in sport management. The experiences of experts highlighted a decrease in the average quality and motivation of students in sport management programs. One of the reported reasons for this was the lack of legal support in attracting specialized individuals in this field to the job market.

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.

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.
