The purpose of this research was to present the basic football development model of Iran with an interpretative structural approach. The current research was applied in terms of purpose and descriptive in terms of method, which was conducted in a mixed qualitative and quantitative manner. Sampling in the qualitative section was based on a specialized and targeted panel and equal to 18 people. In the quantitative part, the statistical population included the officials and experts of the youth and talent search committee of the football federation, provincial football boards, and managers of football clubs and schools. First, 384 people were selected as a sample by stratified random and then by available non-random method. The research tool was a researcher-made questionnaire and a structured self-interaction form. The validity of the questionnaire was confirmed by 10 sports management professors and its reliability was confirmed by Cronbach's alpha test (α=0.88). In order to model the components, the interpretive structural modeling technique was used. The findings showed that 78 indicators in the form of 19 components in managerial, motivational and attitudinal dimensions, core competencies, human resources, financial, cultural and social facilities and equipment are effective on the development of basic football. Also, the stratification results showed that the components were structured in seven levels, and the organizational and planning motivating factors were in the seventh level, and the components of income from basic football and rules and regulations were in the first level of the interpretive structural model of the research. It can be said that, in the first place, focusing on the localization of the basic football development program of the leading countries and formulating a long-term operational plan and new training and training programs along with incentive mechanisms will smooth the development of basic football.

The purpose of this study was to investigate the state of Iranian youth football development based on the Grassroots football program. The method of this research is descriptive-survey and it is a type of applied study that has been accomplished in field. The statistic population of study included officials of the Football Federation and National Football Center, top football schools managers and top youth football coaches of Iran (170 persons). According to the Morgan sampling table, 118 persons were selected as the statistical sample. In order to collect data, a researcher-made questionnaire and a standard check-list were used. The validity of the questionnaire were confirmed by the experts and its reliability was determined 0.91 based on Cronbach's alpha coefficient. In order to analyze data, descriptive statistic methods, Kolmogorov-Smirnov Test, One-sample t-test and Friedman distribution were used by SPSS-22. The results indicate that in all components, Iranian youth football does not have a desirable status. Also, the prioritization of the components showed that the highest rank was related to the knowledge of coaches and the lowest rank was related to the financial and marketing. Therefore, the most important practical actions are preparation of the Grassroots' Charter, launching of e-learning opportunities, approval of the monopoly budget, investments in the Grassroots' facilities and equipment development plans, using of sponsors' assistance and the promotion of philosophy and activities of Grassroots football.

 The link between corruption and sport has a long history. Corruption in sports (in all its forms and degrees) is a global phenomenon that continues to threaten the integrity of the sports industry, and is a major challenge for sports managers, clubs, organizations and all elements of the sports community (1). The increasing complexity and nature of corruption has been discussed in many sports. So far, however, little research has examined the state of corruption in sport. In this regard, Szwajdler (2016) in a study examined selected measures against corruption in sports and researchers' opinions about them. It was found that corruption in sports clearly has a negative impact on the health of sports and society (3). The results of Hwang (2016) study also showed that there is a positive correlation between people's perceptions of corruption and the magnitude of national corruption; There is a negative correlation between individuals' perceptions of corruption and corruption in sport; And there was a difference between people's perceptions of corruption at the individual level (e.g., individual recovery), sports corruption, and team level (e.g., team doping), corruption in sport (4).  Due to the prevalence of corruption in sports, so far little research has examined corruption in soccer (9-11). In this regard, prioritizing the factors affecting corruption in soccer from the perspective of experts in this field has been determined that organizational characteristics are in the first priority and economic factors, cultural factors, personal characteristics of employees and rules and regulations, respectively, have caused corruption in soccer (9). On the other hand, so far, no research has examined the factors affecting the incidence and spread of corruption in age-old soccer. Soccer has a special place in discharging the emotions of children, and also in cultivating national heroes and motivating national pride, there are various life lessons in it. In this conscious and purposeful physical activity in the world of noisy environment, it is not only a great field of friendship, competition and struggle, but also a manifestation of high human values ​​in which there are scenes of effort, forgiveness, cooperation, honesty, patience, courage and beauty. Students of this sport are taught the lessons of effort, sacrifice, cooperation, endurance and courage and it is one of the educational tools in the transformation and health of society. Now, if corruption is not eradicated in its most fundamental part, ie at the grassroots level, children will grow up in unhealthy conditions, so it is necessary for corruption in this sport to be given special attention in the grassroots sector. Given the above and paying attention to the fact that there is corruption in all elements of sports, this issue also attracts a lot of attention in soccer. Especially in grassroots soccer, which is not like adult leagues where all the media and people follow the small and big events. The present study has been compiled with the aim of the identification the factors influencing the incidence and spread of ethical corruption and its control methods.

The research method is applied in terms of purpose and in terms of data collection in the field. The statistical population of this research is 150 sports experts aware of soccer issues, consisting of experts in the field of media and soccer, experts in the field of economics and soccer marketing, experts in the field of culture and soccer and experts in the field of refereeing and professional coaching of basic soccer which were selected by cluster sampling method. They form. In order to collect data, field method and a questionnaire identifying the effective factors in the incidence of moral corruption have been used. Confirmatory factor analysis (structural equation model), Friedman test, Amos version 24 and SPSS software version 25 were used to analyze the data.

The results showed that the cause of managerial corruption (β=0.831), the cause of family corruption (β=0.807), cultural corruption (β=0.788), social corruption (β=0.760) and media corruption (β=0.760) have an effect on the incidence of corruption in grassroots soccer. Factors affecting the incidence of moral corruption in grassroots soccer in terms of research samples in order of priority were media corruption, managerial corruption, cultural corruption, social corruption, family corruption.

The findings of the present study show that the factors of managerial corruption, family corruption, cultural corruption, social corruption and media corruption have a significant impact on the incidence of moral corruption in grassroots football. These results are consistent with the findings of Najafikolori et al. (2012), Ghorbani et al. (2019) and Zare et al. (2016) (7, 10, 11). Sport must be accompanied by moral values, principles of chivalry, forgiveness and self-sacrifice, and the observance of moral principles and standards is obligatory on all athletes, spectators, coaches and sports managers. However, this is not the case in practice, and behavioral abnormalities, aggression, cheating, collusion, and lawlessness are increasing day by day in sports settings, and are also evident in the younger age groups, namely infants, adolescents, and young adults. In recent years, researchers have shown that playing football has many benefits in maintaining the vitality and health of children and adolescents (14). Therefore, moral corruption in this group can be a serious threat to the vitality and health of children and adolescents. Shaking the moral values ​​of society, destroying the legitimacy of the government and the rule of law, destroying transparency and accountability, reducing healthy opportunities for progress for individuals, increasing the cost of healthy living are other harmful effects of corruption that are a major obstacle to achieving goals. And are considered social responsibilities (15-18). Determining the extent of corruption in sport is somewhat difficult because, first, the extent of corruption in sport depends largely on the definition of corruption in sport. Secondly, it is very difficult to investigate corruption in sports. On the other hand, the various dimensions of corruption in sports are very diverse. Lack of adherence of society to the observance of moral standards, the existence of lawlessness in the culture of society and the degree of patriarchy in society are the most important cultural factors affecting the tendency to corruption (19). Regardless of which factor plays a greater role in corruption, two basic conditions are necessary for a violation to occur in all circumstances: willingness and opportunity. If there is a desire and opportunity for corruption, corruption will be born and will grow if other conditions are met. Proper knowledge of the history, traditions, values, space and specific conditions of society and prevailing policies in the field of work, appropriate combination of supervision and punishment, participation of community members at the local level in the functioning of units, efficient rules and regulations, free, independent and committed media It can play an important role in controlling corruption (22-25). Also, according to the findings of the present study, the factors affecting the incidence of moral corruption in grassroots football in terms of research samples were in order of priority: media corruption, managerial corruption, cultural corruption, social corruption, family corruption. The present study, like other researches, has faced limitations. This research is spatially limited to a specific part of Iran and this issue limits the spatial generalization of research. Cluster sampling method instead of whole number sampling can be considered as an internal interfering variable. In general, identifying the occurrence of moral corruption and the reasons for its spread can help clubs, organizations and sports institutions to take measures to reduce the rate of corruption in sports, especially the younger age groups. According to the results of the present study, it seems that providing appropriate solutions to help the factors identified in this study can reduce corruption in sports of age groups.

The aim of this study was to investigate the relationship between some anthropometric parameters and physiological tests (physical fitness) in amateur soccer players. The present study was descriptive-comparative carried out as a field study. The statistical population consisted of male adolescent soccer players (9-13 years old) who volunteered to participate in leisure time programs of Basij Sport Organization in centers of provinces. The statistical sample included 153 boys (mean age 11.7±1.2 yr, weight 40.9±9.3 kg, and height 147.5±9.2 cm). Somatotype variables were measured using ISAK instruction. For physiological tests, Sarjent jump, Illinois agility and 540 meter run were used. Data were analyzed by SPSS 18. To investigate normal distribution of data, K-S, descriptive statistics and regression were used (P˂0.05). Results showed that body fat (P=0.00, t=2.8), maturation parameter (P=0.00, t=2.7) and endomorphic component (P=0.00, t=0.47) could significantly predict anaerobic power. Also, height (P=0.00, t= -2.7), weight (P=0.02, t=2.3), body fat (P=0.00, t= -3.9), maturation parameter (P=0.00, t= -3.5), endomorphic component (P=0.00, t=4.3) and ectomorph component (P=0.01, t=2.4) could significantly predict aerobic power. There was no significant relationship between agility and anthropometric variables.

The aim of this study was to survey football talent identification problems. All coaches of the basic football teams of Tehran Asia Vision league in adolescent and youth classes formed the statistical population of this study. 42 coaches were selected as the sample based on Morgan Table. Because there was not a standard questionnaire for this scope, a questionnaire with 5-point Likert scale was designed using the viewpoints of physical education and sport sciences professors and the coaches of basic categories of football national team. The face and content validity of the questionnaire was verified by physical education professors and football coaches and the reliability coefficient was obtained to be 0.86 by Cronbach’s Alpha. After receiving data from the subjects, the data were analyzed based on descriptive and inferential statistics (Friedman Test) by SPSS and EXCEL in order to survey football talent identification problems. The results showed that the most significant problems for football talent identification were: a lack of financial and material facilities for football talent identification, a lack of specialized committees for talent identification in the clubs, a lack of a systematic program for football talent identification, a lack of familiarity with scientific methods of talent identification, a lack of training of experts by relevant organizations for talent identification.

The purpose of this study is to develop talent identification parameters for football. All coaches of the basic teams of Tehran Province for Vision Asia League in adolescent, youth classes formed the statistical population of this study, Statistical sample 42 selected.Research findings is show significant differences between Indexes football Talent Identification. The results show that the most significant parameters of talent identification in football include skill parameter of individual techniques and among the sub-parameters of skill: individual techniques (passing), skill: individual tactics (proper positioning), anthropometric parameters (height), physical-motor parameters (speed) are the most important parameters for talent identification in football. And also 10 TOP index soccer talent identification in order of importance include: ball control, passing, proper positioning, height, passing and penetrating, physique, speed, the power of decision-making and choosing, moving without ball, and accountability.

Using appropriate devices and scientific methods can accelerate the process of sport talent identification and development to achieve championship level, and could also provide condition in which capable and talented athletes obtain highest level performance rapidly, so they will have long life championship. Former researches in scope of sport talent identification usually have been done in order to determine or normalize effective parameters. The purpose of this study was to design football talent identification algorithm based on fuzzy logic which classifies the football athletes. Due to expert opinion, essential parameters of football talent identification which also used in this software are; Cardio respiratory capacity (Physiology), Agility (Ability of motion), Dribble (technical skill) and Motivation (psychology). Norms of elite football player teenagers (14-16 yrs) are also used as index. Then with considering parameters and index, a fuzzy algorithm is designed which classifies football players in Unmatched, Semi-matched, Matched, Brilliant and Rare class. These results can help trainers and coaches in order to select talented and capable football players. In validation and reliability, records of elite junior Brazilian and Portuguese soccer have compared with norms of Iranian elite soccer.
