Abstract
So far, there has been a lot of scattered research on various aspects of the benefits of physical activity for women in various disciplines, but there has been no coherent analysis and theorizing. Therefore, the aim of the present study was to identify, categorize and examine the types of benefits of physical activity for Iranian women at different stages of life and to theorize about the process and impact of experiencing the benefits of physical activity on primary motivations. The research method was Grounded Theory, systematic approach. Sampling was theoretical. Data analysis was performed through continuous "questioning" and "comparison". In-order-to achieve saturation while reviewing specialized texts, semi-structured interviews were conducted with 136 Iranian-women aged 7-78 who were regularly participate in physical-activity in addition to 17 mothers and 6 fathers. The findings of the present study show that the benefits of physical activity for Iranian women can be classified into six general categories: (1) "health development", (2) "motor development", (3) "socio-behavioral development", (4) "enrichment of leisure time", (5) "Beauty" and (6) "Prevention and Treatment". Findings also showed that experiencing the benefits of physical activity strongly influences the modulation of initial motivations and the formation of strong and lasting motivations. According to the research findings; Cultural-sports managers should include all the important benefits of physical activity experienced by women at different stages of life in the content of Iranian women's physical activity promotion programs and do not suffice to provide general and specialized intangible content.

Abstract
This study aimed to investigate the effectiveness of basic taekwondo exercises on the executive functions of children with a learning disorder. For this purpose, 20 boys aged 10 to 12 years with learning disorder in Mashhad were selected and randomly assigned to training and control groups. The training group practiced Taekwondo for 12 sessions, each session lasting 50 minutes, repeating three days a week. The control group also engaged in their normal daily activities during this period. Changes in subjects' cognitive functions were measured before and after the training period by the N-back and the Tower of London tests. Analysis of variance with repeated measures was used for statistical analysis. The results showed that basic taekwondo exercises improve executive functions in the training group; All these changes were significant compared to the control group (p<0/05). Therefore, based on the results of the present study, it can be concluded that basic taekwondo exercises help to improve the executive functions of children with learning disorder by affecting brain areas related to executive functions.

Abstract
Our understanding of the effectiveness of small-sided games compared to other training methods is limited. Therefore, the aim of this study was to compare the role of small side games (SSG) and traditional teaching method on individual and team creativity of 11-12 year old soccer players. To conduct this study, among all the 11-12-year-old children of Iraq who were enrolled in football classes, 30 learners were selected by the available method and were randomly divided into two groups of traditional and SSG education. At first, the pre-test was taken by the video analysis method, and then the participants practiced football skills on the 7x7 field for 16 weeks and 4 one-hour sessions every week. Finally, the post-test was evaluated according to the pre-test. The analysis of the film was done based on the opinion of two experts and according to the previously identified practices. The results were analyzed by descriptive method and 2x2 ANOVA analysis in SPSS 24. The results of the study in the descriptive part showed that appropriate actions, creative and original actions have grown more in the SSG group compared to the traditional group. In this regard, inappropriate actions have shown a further decrease. In the section of inferential tests, the results showed that the effect of the test and test*group is significant for appropriate actions and the effect of the test for total actions showed the same result. In this regard, small side games can be played by placing the player in a small environment, allowing the player to have more opportunities to perform and less time to make decisions, which leads to the improvement of creativity in team sports such as football.

Abstract
The present study aims to investigate the variables of social networks in different positions in basketball. These variables were applied in two levels of analysis: micro (individual) and macro (global interaction of the team). 24 official Chemidoor Club competitions in the 2020 men's Iranian Premier League were selected by available sampling. This research analyzed the network properties of Degree, Betweenness, Closeness, Eigenvector, and Density centrality across teams and positions. The one-way ANOVA for the factor position in the micro-level found statistical differences between the game positions in the dependent variables of Dc: (F(4,15)= 61/29, p= 0/000), Bc: (F(4,15)= 210/11, p= 0/000), Cc: (F(4,15)= 78/55, p= 0/000). However, no significant difference was observed in the Eig: (F (4, 15) = 1/58, p= 0/184). Results of post hoc test indices were significantly different between position 1 (point guard) and other positions. Macro-level team density analysis showed a significant difference between performance results in successful and unsuccessful. The guard player role was observed as the situation that establishes the most interactions with teammates during the competition. Therefore, players with higher degrees were not the ones assisting the most shots. The other players with higher degrees were not the ones assisting the most shots. These results may be used as a tool for coaching to improve their teams’ strategies in concrete, measurable ways.

Abstract
The literature on self-controlled motor learning includes efforts that compare a group of learners who have choices about some aspect of their practice environment with a group who are dependent on those choices. Therefore, several studies have shown that self-control practices have benefits. In the present study, using the self-control approach, the choice order during golf practices, the level of skill accuracy, autonomy, and self-efficacy were investigated. The present research is of a semi-experimental type and was carried out during the 24-hour follow-up period. Twenty-four beginner students were available and randomly placed in the experimental group (n=12) or yoked group (n=12). In the pre-test, the participants took the golf putting test. Then the yoked group used the practicum devices in the order of choice of the experimental group. On the first day, skill accuracy, autonomy, and self-efficacy were measured in the pre-test and acquisition, and then with the retention test. The results of the repeated Measurements analysis test showed that self-control has a significant effect on golf putting skill, autonomy, and self-efficacy. Therefore, a small choice such as the order of practice in the self-control approach can be effective on motor performance and learning, and the psychological components related to them.

Abstract
Physical literacy is a topic that has attracted the attention of sports and health science researchers in recent years, and research is necessary and important to promote physical literacy. In this regard, the aim of this study was to the effect of physical education classroom of dynamic schools on the development of physical literacy of 9-year-old students. To achieve this goal, one class from dynamic schools (31 people) and one class as control group (34 people) were selected. To assess physical literacy, the Canadian Assessment of Physical Literacy was used, which evaluates general body literacy as well as the subcategories of daily behaviors, knowledge and understanding, physical competence, and motivation and self-confidence. The results of covariance analysis showed that there is no significant difference between the two groups for the variable of daily behavior (p=0.506) and knowledge and understanding (p=0.052). But this difference is significant on physical competence (p=0.010), motivation and self-confidence (p=0.01) and the total score of physical literacy (p=0.000). With this solution, all variables improved more in the experimental group than the control group from pre-test to post-test. In general, the results of this study confirmed the positive impact of dynamic schools on physical literacy, which reveals the need to pay attention to the activities of dynamic schools. And its results can be used in schools and kindergartens.

Abstract
The aim of the present study was to investigate the effect of inducing positive stereotypes on perceived competence, interest and motor learning in adolescent girls. Therefore, among all of the adolescent girls in Shiraz, 30 adolescent with the age range of 10-13 years were selected by convenience sampling. Participants performed 10 trials as a pre-test and afterward, they were randomly divided into two groups . The acquisition phase consisted of 50 trials (5 blocks of 10 trials), and the task required participants to perform inside kicks at targets area attached to a wall and touching the ground. Twenty-four hours after the acquisition phase, participants attended retention test (with 10 trials) to check learning effects on them. The participants were asked to answer the questions related to perceived competence and interest before pre-test, after the acquisition phase, and before the retention test. To analyzing data, one way and Mix ANOVAs analysis and Independent T test were conducted using SPSS21 at significance level P≤0.05. The results showed that in the acquisition phase, all groups significantly increased their accuracy, though difference among groups was not significant. Also, the results showed that the induction of positive stereotypes led to higher perceived competence and motor learning in adolescent girls

Abstract
The aim of this study was to comparison of the effectiveness of linear and non-linear pedagogy on locomotor motor skills Performance and movement motivation in children with developmental coordination disorder. The statistical population was all children with developmental coordination disorder in Urmia. The statistical sample consisted of 30 boys (age = 9.35 ± 1.37) who were selected from Urmia schools using the available method. MABC-2 test was used to diagnose developmental coordination disorder, TGMD- test was used to evaluate locomotor skills, and motor motivation test was used to evaluate movement motivation. To carry out this study, the participants practiced two 50-minute sessions of motor skills interventions in two linear methods (15 people) and task manipulation (15 people) for eight weeks. Variables were measured before and after the interventions. The results of covariance analysis showed that non-linear training compared to linear training significantly improved both in movement skills (p=0.04) and motor motivation (p=0.000) than the linear group. According to these results, non-linear methods considering the individual characteristics of each child are helpful for helping children with movement disorders. Considering the unique characteristics of each child helps to improve motor skills and to have enough motivation to continue the activity. Therefore, the use of non-linear methods is suggested for children with developmental coordination disorder.
