The objective of this research focuses on developing models for maintaining ball possession in games of FIFA World Cup South Africa 2010TM®. We analyzed the 64 matches of the 32 participating teams, excluding the presence of four games with extension, for a total sample of n = 120 total teams. The playing field was divided into nine zones. It was used as a criterion the total time of possession of teams in the game to sort the top models (MSup, values > 75o percentile, n = 23 teams), general models (MGer, values ≤ 75o and ≥ 25o percentile, n = 73 teams) and lower models (MInf, values < 25o percentile, n = 24 teams). We used measures of centrality and dispersion and plan inference, normality test of D'Agostino-Pearson (k samples, n ≥ 20), one-way ANOVA for repeated measures followed by post hoc Tukey, with p < 0,01. The results of this study indicate that despite the proposed top model characterized by greater time of possession in games in relation to the general and lower model, there was more time of possession only in areas of the midfield and lateral attack.

The aim of this study was to determine the effects of futsal training in university players. Participated in the study 12 athletes aged between 18 and 26 years (22 ± 2.9 years) men's soccer team of the University Center UNIRG, who were enrolled in state futsal league 2010. The tests and data collection (fleximetry) were applied to the hip, knee and ankle, and performed at three different times following the calendar game: nine weeks before last week's League (T1), five weeks before the last week of the championship (T2) and, a week before the end of the championship (T3). The training sessions coincided with the flexibility training sessions specifically for futsal and consisted of 5 minutes of general warm and subsequent extensions and flexions maintained for 15 seconds at maximum amplitude. Statistical analysis was obtained from the average and standard deviation of the values found and fixed at the 5% critical level (p <0.05). The main findings indicate significant improvements in flexibility in the lower limb of athletes in all joints investigated. We conclude that the futsal training provided improvements when compared to a previous moment without intervention, proving to be effective in the performance of athletes. Key words: Futsal. Training. Flexibility.

This study aimed to investigate the occurrence of aggression on referees in the games organized by the Rio Grande do Sul Football Federation (FGF) where there was no press coverage. The sample was composed by 50 subjects of FGF Referee Panel, of which 26 operate as referees and 24 like assistant referees. For the survey data, interviews were conducted using a semistructured questionnaire aiming to standardize the responses, which were subjected to content analysis. Thus indicating a low rate of physical aggression (18% of sample), and most of these abuses occurred in the presence of the media, which made us believe that the media itself does not inhibit aggressive behavior. Key words: referee, football, press, physical aggression.

This quantitative and descriptive study (Thomas, Nelson, Silverman, 2007) aimed to verify if local factor influences the results of football matches. All the games that took place in the Gaúcho Championship, in the A and B football division, from 2000 to 2011, were analyzed. They totaling 5,047 matches and 11 games, in division B, were suspended. Data were collected on the site of the Federação Gaúcha de Futebol and were analyzed through descriptive statistics. The results indicated that, from 5,047 games played at home, there were 2,550 victories, 1,303 draws and 1,194 defeat. The findings of this study, concerning the prevalence of victories of the hometeam meet other studies already carried out (Corneya e Carron, 1992; Silva, 2004; Medeiros Filho e Haddad, 2008; Miguel, Calvo e Marcos, 2008; Silva, Medeiros e Silva, 2010; Colombo, 2011; Xavier, Casali e Guedes, 2011). Nevertheless, it is important to recommend that further researches should be performed correlating the impact of local factor with other variables that could influence the results of games. Key words: Football. The Local Factor. Victory. Analysis of the game. Championship of Gaúcho Football.

Objective: The present work will collect, interpret and understand data regarding the selection process applied to male football athletes from the category Under 15. Materials and Methods: Firstly, a structured questionnaire with ten questions was applied face to face to the social actors who directly participate in the selection process of clubs such as Náutico Capibaribe, Sport Recife, Santa Cruz and Atlético do Porto. Later, the data from the questionnaire were analyzed based on the relevant scientific literature. Considering the data collected, this work used the descriptive statistics like absolute, relative and average frequency. Results: It was found that, regarding the selection process, clubs in Pernambuco still use the draft as the main way of access of youngsters to the clubs. Besides, it was observed that main selection criterion considered is the technical aspect presented by the athlete, the preference of clubs is for strikers, that most athletes are selected from the metropolitan area of Recife and the goalkeeper position is the most difficult to find. Discussion: Throughout the work we will engage with the relevant scientific literature review and make the necessary comparisons. Conclusion: It was found that there is no consensus either about an adequate way to identify young talents, or regarding the age or methodology used for this. For this it would be very important to restructure, organize and create managerial processes of order to professionalize the department basis, creating a unique department in the capture and management of grassroots football. Key words: Football, Talent selection, Under 15, Pernambuco.
