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: "health development", "motor development", "socio-behavioral development", "leisure enrichment", "Beauty" and "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.

Abstract
The aim of this research was to identify and prioritize the criteria for selecting youth basketball coaches using the DEMATEL technique and network analysis in fuzzy conditions. The statistical population consisted of 10 university experts with experience in coaching youth basketball teams or relevant education in sports human resource management. Initially, criteria for selecting youth basketball coaches were identified through library studies and expert interviews. After identifying the criteria, the DEMATEL method was employed to clarify the internal relationships among them. Subsequently, a questionnaire was used to determine the importance of each criterion through the Analytic Network Process (ANP).
The results indicated that among the main factors, technical and legal competence, psychological and communicative skills, and willingness to grow and excel held higher importance. In terms of sub-criteria, holding a coaching card, participating in special coaching courses, and mastery of growth psychology concepts were prioritized. Ultimately, all identified criteria significantly influence the selection of youth basketball coaches. Therefore, it is essential for managers to consider these criteria when choosing coaches for youth teams. This research provides a structured approach to enhance the coach selection process, ensuring that qualified individuals lead youth basketball programs effectively.

Abstract
Objectives: Using auditory concurrent feedback with the goal of gaze path learning is a novel method in the attention field. The present study aimed to determine the effect of bisensory feedback using eye movement sonification on the decision-making of the badminton clear shot direction.
Method: In a semi-experimental strategy, with pre-post design without a control group and clinical method, participants performed recognizing the direction of the shot under unisensory and bisensory training conditions. Response accuracy, response time, and fixation duration were measured in the pre-test, immediate retention, and delayed retention.
Results: The results showed that in the immediate and delayed retention, the bisensory group had higher response accuracy and shorter response time than the unisensory group. The bisensory group had a longer fixation duration in key areas than the unisensory group in both times.
Conclusion: The use of auditory feedback can probably be considered as a way to improve decision-making skills at the novice level.

Abstract
Introduction: Motor learning has been measured differently based on two essential factors of OPTIMAL theory (autonomy support and increased expectations). Giving choice has been widely used in this field, but it has not been fully investigated in the learning of throwing skills according to these two factors.
Purpose: The present study aimed to investigate the benefits of giving choices using the order of practice choice on learning the putting accuracy skills and the psychological components of perceived autonomy and self-efficacy beliefs.
Method: In this quasi-experimental study, 24 novice participants with a mean age of 24.87 ± 3.26 were randomly assigned to experimental (n=12) and yoked (n=12) groups. Immediately after a 10-trial pretest, participants practiced three new tasks (visual cues, auditory cues, chest bar) to putt a golf ball into the center hole in six blocks. Then, the learning was measured during a 24-hour follow-up period under conditions completely similar to the pretest (10 trials).
Findings: The study assessed participants' skill accuracy, perceived autonomy, and self-efficacy across all three experimental phases. Mixed-design analysis of variance revealed that the order in which practice was structured significantly influenced golf putting accuracy, self-efficacy, and perceived autonomy (p ≥ 0.05).
Conclusion: The possibility of task-related small choices enhances perceived autonomy self-efficacy and, which leads to improved motor learning. Therefore, these findings are consistent with optimal theory.

Abstract
Aim: The purpose of this research is to measure and model the release of carbon monoxide pollutant in the surrounding space of Azadi Stadium in Tehran during sports competitions.
Methods: Basic data were obtained by laboratory measurements and inquiries from specialized centers. Modeling was done by Austal View software, Version 7 and under four scenarios. The prediction of pollutant concentration was simulated at a height of 5 meters. The modeling area was considered a circle with a radius of 1 km from the center of the site. The resulting data were compared with national and international standards. The initial concentration of the pollutant in the hot and cold seasons of the year was 1.432 ppm and 2.331 ppm, respectively.
Result: The amount of pollutant emission for the state of "completion of parking capacity" and "semi-complete state" was 81.45 and 37.5 kg, respectively. Zoning maps showed that in all four scenarios, the highest amount of emission was in the east direction. The highest amount of carbon monoxide production and emission is related to the first scenario (completion of the parking capacity and the cold season of the year) and the lowest amount of carbon monoxide pollutant emission is under the fourth scenario (failure to complete the parking capacity and in the warm season of the year). Although the condition of this pollutant in Tehran's Azadi sports complex and during sports competitions has not exceeded the standard.
Conclusion: By using management and engineering solutions such as: not keeping lights on in place, using exhaust filters, properly designing the parking space and reducing the duration of stopping, it is possible to avoid the production and release of a large part of pollutants.

Abstract
Background: Firefighters encounter critical and hazardous situations that necessitate optimal and rapid performance during emergencies. Given the complexity of their responsibilities and the psychological pressures stemming from daily tasks, it is crucial to investigate methods to enhance their performance. This study aimed to assess the impact of mindfulness exercises on the coordination, executive functions, and specialized motor skills of firefighters.
Aim: The study utilized a semi-experimental design with pre-test and post-test assessments.
Methodology: This study was a quasi-experimental design with a pre-test and post-test involving a control group. The statistical population consisted of firefighters from fire stations in Shiraz province, and six stations were selected using a multi-stage cluster sampling method from a total of 24 stations. Thirty firefighters were matched based on their pre-test scores and randomly divided into two groups of 15 each: a control group and an experimental group. The experimental group received mindfulness training for eight weeks, with three 30-minute sessions each week. The assessment tools included the Grooved Pegboard Test, the N-back Test, and specialized motor skill tests for firefighters. The data were analyzed using Analysis of Covariance (ANCOVA).
Results: The mindfulness intervention significantly improved the experimental group's performance in coordination (p < 0.001), specialized motor skills (p = 0.044), and executive functions (p < 0.001). However, no significant difference was observed in pipe opening/closing tasks (p = 0.087).
Conclusion: Mindfulness exercises may enhance critical abilities in firefighters and could inform the design of effective training programs.

Abstract
The purpose of the present study was to investigate Effect of self-regulation from biofeedback exercises on the learning of dart throwing skill under pressure conditions. Participants were 28 undergraduate male students of the University of Tehran who were selected in an accessible manner as they were right-handed and had no experience in dart throwing and working with biofeedback devices. These numbers were randomly divided into four groups of visual, auditory, combined and control biofeedback. The number of biofeedback training sessions was 4 sessions with pre-test, post-test and retention sessions in 4 weeks. The results of analysis of covariance and mixed analysis of variance with repeated measures showed that visual, auditory and combined biofeedback training had a significant effect on the learning of dart throwing skills under pressure (P <0/05). According to the research findings, it is suggested to use biofeedback of temperature and galvanic response of the skin, visually, audibly or in combination, to learn darts throwing skills and skills similar to and close to darts throwing skills, as well as feedback of biofeedback sessions. Prioritize the combination biofeedback to see the best results.

Abstract
Background and purpose: This study was conducted to determine Relationship between participation motivation and Social – Economic Status of youth in Tehran. Method: This study was cross-sectional and done by questionnaire. The analyses were based on data that collected from sports clubs in four Tehran regions (North, South, East and West), (n= 130) young people (65 male, 65 female) were selected randomly and completed the participation motivation questionnaire (PMQ) and socioeconomic status questionnaire. Result: results of Pearson’s correlation showed that there was a significant positive relationship between motivational component subscales of participation motivation in sport and socioeconomic status in young people (p ≤ 0.05). Conclusion: The present study determined there was a significant relationship between income statues, economic-class, parents’ education level and sport participation motivation. The finding revealed that the families with high-and middle- economic class and income have a greater incentive to engage in physical activity. The education level of parents, especially fathers play an important role in encouraging their children to participate in physical activities.

Abstract
People need coordination to accomplish joint tasks and pursue the same goal. The aim of this study was to investigate the predictive mechanisms in interpersonal coordination among elite rope jumping players. The research strategy was descriptive and applied and the statistical community consisted of 24 elite rope jumping players (14 to 18 years old). Subjects practiced various rope jumping tasks (individual and joint rope jumping at the same or different distances with online landing) for eight weeks until they could do them properly and without online feedback. The researcher used a Vicon motion analysis device to record three-dimensional movements of players' feet and ropes whirling and examined spatial and temporal parameters. The results of independent t-test, repeated measures ANOVA and one-way ANOVA showed that people were similar each other in movement onset time, hand-foot deviation time, timing variation in rope whirling, and landing position (P> 0.05), while a significant difference was observed in their jump height and movement time. So, players simulate each other's movements to coordinate with each other in different tasks, and their efforts distribution doesn't related to task characteristics. In fact increasing difficulty as well demand of joint task, amount of interpersonal coordination and consequently prediction ability will increase.

Abstract
The present study aimed to examine the differences and similarities between men and women in the factors shaping identity with Iranian football clubs, based on the psychological continuum model. To this end, 31 in-depth semi-structured interviews were conducted with two groups of Iranian male and female football fans, analyzed through content analysis grounded in the psychological continuum model. Data analysis was carried out through three stages of coding—open codes, categories, and themes—until distinct and meaningful themes emerged. The findings indicated that, according to the psychological continuum model, men and women differ in the three stages of awareness, attachment, and loyalty, whereas their similarities were most evident in the attraction stage. Despite some commonalities in identity formation between male and female fans, the study found that women’s fandom discourse in Iran has yet to be recognized as a professional and legitimate phenomenon. The greater emphasis by women on the awareness stage suggests that their knowledge of football and their favorite team is still in the process of formation.
