The aim of this study was to compare the effect of training type (full-error and error-less) and skill level on the development of mental representation of putt golf skill. For this purpose, 44 undergraduate physical education students (22 women, 22 men; mean age 22.34 and standard deviation 4.37) were randomly divided into two groups: error-less (near-to-far) and full-error (far-to-near). The two groups practiced in the one-day acquisition phase of 3 blocks of 10 attempts for throwing distances (25, 50, 75, 100, 125, 150 and 200 cm). The error-less group started training from the closest distance to the goal and reached the farthest distance, respectively, but the full-error group started training from the farthest distance and finally reached the closest distance. At the end, they were tested immediately. One day after the acquisition phase, delayed retention tests, single task transfer (from a distance of 225 cm) and dual task transfer (from a distance of 200 cm simultaneously with audio playback) were performed. To compare the effect of error-less and full-error training on the acquisition, retention and transfer of putt golf skills, data analysis of the acquisition stage was analyzed by repeated measures analysis of variance (2×8). SDA-M test was used to measure the structure of mental representations formed in the two groups before and after the acquisition period, and hierarchical cluster analysis  0.05) was used to analyze the mental representations.  Our Findings showed significant functional changes in the post-exercise mental representation structure, suggesting that motor skills are associated with functional adaptation of action-related knowledge in long-term memory.

In scientific marketing models, attention is the main step in the effectiveness of advertising. That's why, competition over attention to advertisement has been of prime importance for the sponsors and marketers. However, sport marketing research has not yet been able to gain a proper understanding of the factors that influence the viewer's attention to advertising while watching a sport event. Different methods of data collection and using different evaluation tools can also help managers and sponsors make the right decisions. This semi-experimental research has compared the methods of evaluating TV viewers' attention to advertising through sport. For this purpose, 60 targeted sampling in the form of two groups of women (n = 30) and men (n = 30) watched the football match between Esteghlal and Persepolis in a laboratory site. While samples were watching the football match, meantime designed advertisements were presented too, the viewer's eye information was stored by the eye tracker in the form of fixation and duration. In addition, at the end of the test, the participants' attention to advertising was evaluated using an attention questionnaire. Analysis of the findings showed that in evaluation of the viewer's attention to advertising by questionnaire; there is no difference between males and females. But in both of Eye Tracking variables, females paid more attention to advertising than males. Also, the correlation between the results of the questionnaire and the Eye Tracker was not significant. Finally, in order to achieve new results and to develop the advertising industry, as well as identifying the factors affecting the effectiveness of advertising, it is better to use neuromarketing tools as a complement to other methods of data collection (questionnaire, interview, observation).

Video feedback is a type of augmented feedback that includes showing an athlete or performing a skill with a video clip of oneself or another person performing a particular skill. The aim of the present study was to determine the effectiveness of dyad training with video feedback on learning crawl swimming. For this purpose, 24 male students ranging in age from 11 to 17 years, who had no previous experience in learning crawl swimming, formed two groups of 12 people in dual practice and dyad training with video feedback. Both groups were first justified by the instructor, then in the double exercise group, one of the trainees entered the water and the other watched him perform out of the water, and after trying, they reviewed the mistakes and movements with their friend. in the dyad rehearsal group, one of the friends filmed another performance and showed it to him. The training intervention lasted for 8 sessions and 10 training attempts in each session. After the end of the eighth session, the 10-meter breast crawl swimming acquisition test was performed, and then a reminder test was performed again one week later and filmed. The results showed that the two groups had significant differences in both acquisition and retention, and the dyad training group with video feedback performed better overall. Based on the results, it can be concluded that the dyad training with video feedback method, in addition to being cost-effective in terms of energy consumption and training space, is also more effective than dyad training in swimming training.

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.

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.

Introduction
With the expansion of information and communication technology and its introduction into the workplace, the world has witnessed the close relationship between the application of information technology in organizations and the improvement of performance, as well as the better and faster achievement of organizational goals. Social media, especially Instagram, creates a space for users to express their opinions, allowing companies to contact users directly and without intermediaries, at the right time and with minimal cost. With an understanding of the importance of technology in sales, we analyze the factors affecting the sales of sports goods in the virtual space of Instagram.
Methodology
This research aims to provide suitable suggestions to companies active in the production and sale of sports products to increase their sales. It utilizes textual data from comments and captions on Instagram and examines and analyzes posts and user opinions regarding sports products (specifically two brands: Adidas and Majid). The analyses were conducted in two sections: the first section (captions) analyzed the methods and manners of the advertisements by the sellers of the brands' products, extracting their advertising patterns and techniques. In the second section (comments), user opinions on the products presented on Instagram were examined and analyzed. Text analysis (posts and user comments) and sentiment analysis were key components of the analysis. For analyzing user comments, data obtained from the Instagram API, including three key parameters: the user's name, the date and time the comment was posted, and the content of the comments, were evaluated.
Discussion
The research findings indicate that companies, sellers, and brands should have a very organized plan for advertising throughout all periods of the year. Continuous interaction and proper activity with social network users can also play a role in increasing the motivation of representatives across the country. The study emphasizes that user-generated content (comments) is an effective way to increase the connection between a brand and its audience. Therefore, user feedback must be used in the manner described (the method implemented for analyzing comments) to increase sales and user satisfaction. Additionally, the findings emphasize identifying and establishing relationships with users to maintain and increase customer loyalty, particularly those who post numerous comments on advertised products on Instagram, as they can be used as an advertising campaign for the brand. This study provides a suitable solution for the proper presentation of sports products and advertising on social networks to make the products more well-received.

The purpose of this research was to investigate the effect of manipulation of task constraints on functional indicators and cognitive status of the elderly. In this research, 30healthy elderly were randomly selected and placed in two intervention and control groups. Analysis of covariance was used to evaluate the homogeneity of the slope of the regression line and to compare the mean of the pre-test and post-test data. Data analysis was done using SPSS software. The results showed that the application of the exercise protocol for manipulation of task constraints improved strength(P=0.006), cardiovascular endurance(P=0.010), agility(P=0.001), composition(P=0.003) and Mental status(P=0.002) of the elderly in the intervention group. In addition, the results indicate that the flexibility of the control group decreased significantly from the pre-test to the post-test(P=0.007). The results of the analysis of covariance by removing the effect of the pre-test showed that the body composition variable did not differ significantly from the pre-test to the post-test stage(P=0.264). It seems that exercises with the manipulation of task constraints are effective on the performance and cognitive indicators of the elderly. Therefore, it is suggested to consider the exercises with the manipulation of task constraints to improve the quality of life of the elderly.

This research aimed to design a personal branding model for elite individual athletes, drawing upon findings from previous studies. Employing a qualitative approach and Glaser constructivist grounded theory strategy, data were collected through in-depth, semi-structured interviews with 18 national and international champions and experts in sports marketing, selected via purposive sampling. Data collection continued until theoretical saturation was reached, and analysis was performed using MAXQDA 2022 software. The study's findings were categorized into three main axes: influencing factors, development strategies, and consequences of personal branding. Following an initial analysis of 251 propositions, 443 final frequencies were prepared for categorization. The research extracted four core concepts in personal branding and identified three main categories of influencing factors: "environmental factors," "individual athlete characteristics," and "athlete performance characteristics." In the strategies section, "enhancing individual capabilities," "striving for successful performance," and "branding education" emerged as prominent categories. Furthermore, the consequences of personal branding were categorized into "positive" (encompassing political, economic, individual, social, and athletic dimensions) and "negative" outcomes. Positive branding outcomes included economic benefits (revenue generation), individual growth (becoming a role model), social impact (increasing public awareness), and athletic advantages (enhancing sport popularity). Conversely, mismanagement could lead to negative consequences such as unethical attention or corruption. This study integrates these findings to offer a practical model for personal branding among individual athletes.
