ABSTRACT Introduction: Soccer is the most popular sport in Brazil and worldwide, but there is insufficient data on the eye health of soccer players, and eye conditions may affect the well-being and performance of these athletes. Objective: To perform an ocular evaluation of a representative sample of professional soccer players from Brazil. Methods: This was a cross-sectional study conducted over four consecutive years (2009-2012) at a single professional soccer club in Brazil. The ophthalmology evaluation was performed by the same ophthalmologist in each sample. Prior to the ophthalmology evaluation, all participants filled out a questionnaire to provide the following demographic data: age, position, use of contact lenses or ophthalmic drugs, symptoms, previous ocular surgery, and date of the last ophthalmology evaluation. Visual acuity, intraocular pressure (IOP) and color vision were tested during the ophthalmologic examination, and ophthalmoscopy and biomicroscopy exams were performed. Results: One hundred and twenty bilateral ophthalmology evaluations were performed in 84 professional soccer players between 2009 and 2012. Pinguecula and pterygium were the most common conditions found in the athletes’ biomicroscopy exams, corresponding to 63% (38/60) and 17% (10/60) of abnormalities, respectively. In the contrast sensitivity evaluation, only one athlete was color blind. No significant associations were found between the position of the athlete and the results of the biomicroscopy and ophthalmoscopy exams. Conclusion: Despite the high prevalence of abnormalities found in the ophthalmology evaluation, most refractive abnormalities did not require correction, and the biomicroscopy abnormalities were mostly benign. Level III; Study of non-consecutive patients.

In this paper we propose a DEA (Data Envelopment Analysis) based ranking for Brazilian soccer teams. Ranking is a major issue for the soccer clubs, either when looking for sponsorship or expanding their supportive group. We first include value judgements, applying a method to consolidate the results of the national and international matches. Then we use both aggregate results as outputs for applying the DEA model. Rankings published by the Brazilian Soccer Confederation (CBF) and 'Placar', a traditional sports magazine, do not give any credit to international titles and national cups, focusing only on the results in the National League. We compare the DEA ranking with the Federation's and the magazine's, raising some controversial issues and drawing unexpected conclusions.

Abstract The aim of this study was to identify the morphological configuration of youth athletes from professional soccer clubs and to verify their differences according to the tactical position on the field. Overall, 67 male players aged 15 to 17 years were evaluated. The examined anthropometric measurements included body mass, body height, skinfolds (triceps, subscapular, supraspinal and medial calf), girths (flexed and tensed arm and calf) and breadths (humerus and femur). For statistical purposes, analysis of variance and post hoc Bonferroni and Kruskal-Wallis tests were used. We concluded that goalkeepers were heavier and taller than center backs (p = 0.015 and p = 0.001), midfielders (p = 0.005 and p <0.001) and center forward players (p = 0.024 and p <0.001). The average somatotype for defense, forward and goalkeeper positions was a balanced mesomorph. Midfield players showed ectomorphic-mesomorph characteristics. It was concluded that goalkeepers were characterized as being taller and heavier and that somatotype features of athletes were similar between positions, except for midfield players

The purpose of this study was to perform a survey about the prevalence, type and location of the injuries occurred in athletes of different modalities during the 53th Regional Games held in 2009. A total of 182 injured athletes being treated at the physical therapy clinic were included. Physical Therapy evaluation was performed to determine the anatomic location and type of injury, as well the sport modality. The results showed that mean age, height, weight and BMI were 23 years (±5.9), 1.73 m (±0.11), 71 kg (±14.22) and 24 kg/m² (±4) respectively. Proportionality to the number of athletes, handball athletes presented with higher number of injuries (4.25%), followed by indoor soccer players (3.7%), basketball (2.48%), volleyball (1.72%) and soccer (1.63%). The most common type of injury were sprains with 29.7% of cases (n=54) and mostly from soccer players; followed by contracture - 26.9% (n=49), mostly from basketball players; and contusion -25.8% (n=47), mostly from handball and indoor soccer players. The type of injury showed a significant association with the sports modality (p=0.0016). The lower limbs accounted for 71.4% of all injuries including knee (23.1%), ankle (18.1%), thigh (17.0%), leg (10.4%) and spine (9.9%). Preventive actions to avoid athletes' injury should be implemented in order to reduce the number of injuries in sports competitions such as in the Regional Games.

ABSTRACT Introduction Various studies have been developed and published in relation to the recommendations for physical activity and associated factors. However, there is a lack of studies that detail the places where physical activity is practiced, as well as its frequency, duration and volume. Objective To describe the places, types, frequency, duration and volume of physical activities performed by adolescents in Curitiba, Brazil. Methods A cross-sectional study conducted in 2013-2014, through a household survey with 495 adolescents (12 to 17 years). The places used, and the frequencies of the practice of physical activity were self-reported as either “goes” or “does not go.” The practice of physical activity was determined through the Physical Activity Questionnaire for Adolescents, by type, frequency, duration and weekly volume. The types of physical activity were described with frequency distribution, weekly frequency, duration, and volume, by the median and interquartile range. Gender comparison was tested with the Chi-square and Mann-Whitney U tests (p<0.05). Results The most frequently reported places for physical activity were public squares, parks, soccer fields, schools and sports halls. Soccer fields, schools, sports halls and skate parks were more used by boys, while girls attended gyms (p<0.05). The physical activities most practiced were soccer, skating/rollerblading, cycling, walking and active games. A higher proportion of boys practiced soccer, skating/rollerblading, cycling, running/jogging, and basketball (p<0.05), whereas the physical activities most practiced by girls were walking, walking the dog, dancing, playing games, and gyms (p<0.05). Sports (720 min/week), aerobic exercises (400 min/week) and conditioning exercises (345 min/week) were the activities with the highest weekly volume. Boys showed higher weekly frequency, duration and volume of practice of sports and active games than girls (p<0.05). Conclusion Public places with structures were the most used places, and sports were the most practiced activities. Level of Evidence III; Study of nonconsecutive patients; without consistently applied ‘‘gold’’ reference standard.

Previous findings of skewed birth date distributions among sports professionals have been interpreted as evidence for a systematic discrimination against children born shortly before the cut-off date for each age grouping. Alternative explanations for these findings exist, however. This research therefore attempted to replicate the effect in a cross-cultural comparison. A strong relative age effect in professional soccer was found in Germany, Japan, Brazil, and Australia, showing that the effect is independent of different cut-off dates and a variety of climatic and sociocultural factors. A shifted peak in the birth date distribution of Australian soccer professionals paralleling a corresponding change in the cut-off date in Australian soccer in 1989 was also established. This pattern of results provides strong evidence for the cut-off date in youth soccer as the main cause for the relative age effect in professional soccer.

AbstractThe aim of the present study was to analyze motor activities of soccer players in seven consecutive rounds of matches of the 2014 World Cup in Brazil and to compare the performance of the world champions, the German national team with other participating teams. The study sample comprised 905 observations of 340 soccer players, who played full-time matches in all seven rounds of the tournament. The study was conducted using data collected from the Castrol Performance Index, a kinematic game analysis system that records movements of players with semi-automatic cameras. The following variables were analyzed: total distance covered, the percentage of total distance covered at high intensity, the number of sprints, frequency of sprints and peak running speed. A statistically significant increase (p ≤ 0.01) was noted in total distance covered, the percentage of distance covered at high intensity and total number of sprints, between the quarter-finals and semi-finals of the World Cup tournament in Brazil. The German national team covered a significantly longer total distance (p ≤ 0.05) and had a greater percentage of distance covered at high intensity (p ≤ 0.001) than players from other teams. The obtained results point to the necessity of development of players’ aerobic endurance and speed-endurance abilities while preparing for top-level soccer tournaments. Winning a soccer championship requires players to run longer mean total distances and longer distances at high intensity during a single match.

This manuscript discusses the contamination and dissemination of COVID-19 within sports competitions. Data related to the number of athletes in the first division of Brazilian soccer were used as a starting point. After the competition was resumed, 302 out of 653 players tested positive for COVID-19. Compared to the rate for the total population of Brazil, that number is extremely high and reveals major differences in implementing preventive measures as well as controlling transmission. This can be explained by differences in financial resources to support protocols in strict ways, or even by the fact that the individual social dynamics of athletes did change despite the new life style imposed by the pandemic.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n1p72 In soccer, an attack begins with ball recovery. Therefore, the consistency of this performance indicator during a match and its balanced distribution in the field zones can be one of the distinct characteristics of successful soccer teams. This study aims to investigate the performance consistency of ball recovery during a match within several time periods (6 periods of 15 min) and zones (four zones). To this end, observational methodology and software Focus X2 were adopted to evaluate 28 matches of semi-final teams at FIFA 2014 including Germany, Argentina, Netherlands, and Brazil in terms of ball recovery frequency. In total, 3222 performances were recorded. All teams in each match and in whole competition had homogeneity of distribution of ball recovery during the time periods (χ23=1.597, p=0.66). The results of time-zone evaluation indicated that Netherlands and Brazil teams did not have performance consistency on all field zones (χ2 15=31.29, p=0.008 and χ2 15=37.53, p=0.001, respectively). Most ball recoveries were made in the defensive and middle-defensive zones in accordance with modern soccer. It was found that for a soccer team to be successful, it requires a space distribution of experienced players in the field, which leads to power balance for redesigning a team to be offensive in all zones.

The following article addresses the exploitation of child labor in sports, analyzing the legal regulations applicable to soccer teams in Brazil. In this sense, and considering the need to investigate further the consequences for children and adolescents, the following problem emerges: how does Brazilian legislation seek to impose limits that guarantee the protection of children and adolescents in the sporting sphere in Brazil? The approach applied in this article is the deductive method. The source of the research is the bibliography on the subject and the legal framework. The article has three specific objectives: to contextualize the exploitation of child labor and its historical aspects; to address the exploitation of children and adolescents in soccer; and finally, to analyze the legal protection for children and adolescents in terms of child labor in Brazilian soccer. We identify the existence of a limitation in Brazilian legislation, which imposes restrictions against the exploitation of child labor by children and adolescents in sports, seeking to guarantee their right to a healthy childhood and adolescence, as well as to guarantee the full protection of their rights. Such legal provisions converge with international provisions, especially those laid out by FIFA (Federation International Football Association).

ABSTRACT Introduction: It is known that ingestion of carbohydrate-containing beverages can enhance sports perfor-mance. However, many teams do not have sufficient financial resources to invest in commercial products and need to prepare their own hydration drinks. Jacuba is a beverage used as sport drink (source of carbohydrate) in soccer clubs in Northeastern Brazil. Objective: To evaluate the influence of two beverages with carbohydrate on blood glucose, dehydration and fatigue in a soccer team of Northeastern Brazil. Methods: Twenty-two soccer players were evaluated in two days of physical training, with ingestion of water ad libitum and two beverages: 1) maltodextrin-based drink, or 2) Jacuba. Capillary blood glucose was measured before and after training. Fatigue was assessed using Borg Scale after exercise. To evaluate the dehydration of the athletes at the end of exercise, the urinalysis test and the verification of the body mass change during the training were performed. Results: Blood glucose changed to 13.1±29.5 mg/dL and 7.6±22.2 mg/dL on training days with consumption of maltodextrin and Jacuba, respectively, without statistical significance. There were no changes in body mass and in water and total fluids intake in the two days of training. The Borg Scale score after training was 15.2±2.6 and 14.9±3.0 for maltodextrin and Jacuba, respectively (p=0.12). Conclusion: Jacuba can be used to improve hydration and maintain blood glucose in soccer players because their results do not differ with those of mal-todextrin-based drink.

Abstract Introduction: In soccer, the players’ positions have been associated with specific functional overload, which may cause sports injuries. Objective: To investigate the occurrence and characterize sport injuries according to soccer player position. Methods: 232 male soccer players (129 professionals and 103 amateurs) from different sport teams in Mato Grosso do Sul, Brazil, were distributed in groups according to their soccer player position. Besides anthropometric characteristics, sports injuries were registered by using a referred morbidity survey. The occurrence of injuries was analyzed by means of the Goodman Test. Logistic regression models were used to investigate the relationship between different risk factors and the occurrence/-recurrence of sports injuries. Results: Forwards showed higher occurrence rates of sport injuries than other soccer position groups. Joint injuries in lower limbs constituted the most frequent registered cases. Muscle injuries in the back region were the most registered sports injuries among midfielders, while muscle damages in lower limbs were the primary injuries registered for other line positions. In the etiologic context, contact was the main cause of sports injuries in all groups. Most athletes (195) reported recurrence of sports injuries. Conclusion: The occurrence of sports injuries was higher among forwards. Traumatic joint and muscle injuries were the most prevalent registers in all line positions.

ABSTRACT Despite being the most popular sport in Brazil, soccer suffers from structural problems. Managers working in this reality know little about the factors that determine performance measures in stadiums. Existing research is undertaken according to an economic logic, which attributes importance to a dependent variable only, the total attendance of soccer matches. This article presents an approach that retrieves a sales-based brand equity (SBBE) measure responsible for performance (revenues and proportional demand) in Brazilian soccer stadiums. The methodology involved a process of a canonical regression model with two dependent variables using on-field performance and SBBE as the main drivers of marketing performance. The theoretical assumption underlying the models is the discussion about the multidimensionality of performance and the importance of testing the potential correlation amongst marketing performance variables. The model developed was estimated using all matches of the Premium Division of Brazilian Championship (Série A) held between 2012 and 2017. The main result highlights the power of SBBE as the primary driver of performance in Brazilian stadiums. Corinthians and Flamengo, the two most important Brazilian soccer club brands, exert a positive influence considerably higher than all other competitors.

Scoring goals is the main objective and key to success in soccer. Therefore, all the aspects of this important performance indicator must be studied. Many authors have proposed to study different aspects related to goal scoring in soccer. However, the vast majority of these studies include adult players from professional or amateur teams. The aim of the present study was to analyze the goal scoring frequency in 388 soccer matches of Professional, Under-20 and Under-17 competitions from Brazil in order to compare the results between the different age groups. The impact of the first goal scored on the match outcome was also studied. The frequency of 1100 goals was analyzed by dividing the game in two (first and second half) and six equal periods of time. Data showed that there was a tendency of a greater number of goals scored over time with a higher percentage of goals scored in second half in all three competitions (p

SUMMARYWe evaluated the occurrence of hepatitis C virus (HCV) infection in 97 former soccer players who played in Recife, Brazil in the 1960s and 1970s, and analysed the risk factors for infection, such as history of transfusions, surgery, tattoos, piercings, and the use of illicit drugs or injectable vitamin complexes. Immunochromatographic testing was performed to detect anti-HCV antibodies. All former soccer players were men (mean age 59·2 years), of whom 62 (64%) and 35 (36%) were classified as amateurs and professionals, respectively. Seven (7·2%) tested positive for anti-HCV antibodies; three (4·8%) were amateurs, and four (11·4%) were professionals. In univariate analysis, transfusion, surgery, and use of injectable vitamin complexes were associated with HCV infection, while in multivariate analysis, only the use of injectable vitamin complexes was related (P=0·0005). We observed a high frequency of HCV infection in former soccer players, especially in professionals who used injectable vitamin complexes.

Abstract The aim of the study was to investigate the relationship between tactical performance, somatic maturity, and functional capabilities in young soccer players. Study participants were 48 soccer players (14.80 ± 1.5 years) belonging to an extension project at the State University of Maringa - Brazil. Anthropometric measurements of body mass, body height, and sitting height were carried out. The number of years to peak height velocity (PHV) was used as an index of maturation. Evaluations of functional fitness included the following tests: sit-and-reach, Yo-Yo Intermittent Recovery Test Level 1, handgrip test, modified abdominal test, and vertical jumps (Counter Movement Jump and Jump Squat). Tactical performance was assessed through the System of Tactical Assessment in Soccer (FUT-SAT). Multiple Linear Regression models were used to estimate the relative contributions of functional and maturational capacities to tactical performance. The results indicated weak associations between the tactical performance indices and somatic maturity, functional capacity, and anthropometric attributes (r < 0.40). The Yo-Yo Test contributed to 36% of the defensive tactic performance variation in the under 13 category. These results suggest that the level of maturity, growth status, and functional fitness have limited impact on tactical performance of young soccer players.

PURPOSE This study comprehensively examined the aerodynamic and flight characteristics of modern soccer balls, focusing on their design evolution and performance attributes. METHODS The aerodynamic characteristics of five types of World Cup balls (2006 Germany World Cup, 2010 South Africa World Cup, 2014 Brazil World Cup, 2018 Russia World Cup, 2022 Qatar World Cup) and five types of Euro tournament balls (EURO2008, EURO2012, EURO2016, EURO2020, EURO2024) were examined, along with their respective design changes. RESULTS Through detailed analysis, significant variations in aerodynamic properties among soccer balls used in various tournaments were identified. Recent advancements have resulted in faster transitions towards critical Reynolds numbers, indicating improved stability in flight trajectories. This enhancement was attributed to the augmentation of surface roughness, which plays a crucial role in enhancing aerodynamic stability and overall performance. 2D simulations simulating powerful goalkeeper kicks revealed distinct differences in flight distances among different soccer balls; the Jabulani ball used in the 2010 World Cup exhibited the longest flight distance, while that of the 2024 Euro ball was the shortest. CONCLUSIONS Variations in surface texture significantly impact aerodynamic properties, affecting flight distance, arrival time, and height. This study underscores the significant design enhancements in modern soccer balls that optimize aerodynamic stability and performance, with modifications aimed at improving flight characteristics and enriching player experience.

Context Despite the popularity of soccer at the male first-division youth level, data on the incidence of injuries in Brazil are limited. Objective To prospectively study the injury profile of male first-division youth soccer players during 1 season (January to December 2017). Design Descriptive epidemiology study. Setting Data compiled at a youth soccer academy. Patients or Other Participants The study involved 228 players between 10 and 20 years old from a first-division Brazilian soccer academy. Main Outcome Measure(s) Injury incidence rate was reported as the number of injuries divided by overall exposure (training and match hours) multiplied by 1000. The rate ratio (injury incidence rate during matches in relation to training) was also calculated. Time-loss injuries (ie, physical complaints sustained during soccer matches or training that resulted in a player being unable to take part in soccer training or match play) during the season were recorded. Results A total of 187 injuries were documented in 122 players (65.2%). During the season, 100 389 hours of exposure (5995 hours of match play and 94 394 of training) were registered. The overall injury incidence rate was 1.86 per 1000 hours. In total, 4792 days were lost from soccer activities. The majority of injuries were noncontact thigh muscle disorders and ankle sprains. Injury incidence was greater in matches than in training, and the oldest age group (under 20 years old) had the highest injury incidence rate in matches, while the under 17-year-old group had the highest injury incidence rate in training sessions (22.48 and 3.05 per 1000 hours, respectively). Conclusions Muscle injury incidence rates observed among Brazilian soccer athletes under 20 years old were similar to those reported in professional players. Preventive measures are recommended to reduce injury rates. Additionally, the number of injuries incurred during training was high compared with match play, and training programs need to be assessed so that injury prevention can be improved.

Introduction: Soccer referees need excellent conditioning to withstand the physical and psychological demands of games. Objective: To compare the hemodynamic variables, speed, cadence, and distance coursed of referees during soccer games of series A and B in Rio de Janeiro, Brazil. Material and method: The total number of decisions made during the 10 soccer matches evaluated was 1,224 observable decisions of 10 professional Soccer referees (one per soccer match: 5 in series A and 5 in series B). We used a frequency meter (Polar, model V800, PolarFlow software) and video footage of the games (Sony, model PXW-Z150, 4K). The moments considered were: the decision, 15 seconds that preceded it, and the period from the beginning of each stage to each decision. Were studied the hemodynamic [average heat rate (mean HR), maximum heart rate (HRmax), and minimum heart rate (HRmin)] and motion variables [average speed (Vmed), maximum speed (Vmax), average cadence (cadencemed), maximum cadence (cadencemax), minimum cadence (cadencemin), and distance covered]. Descriptive measures were used to present the results of the variables studied and the Student’s T-Test for independent samples to test the study hypotheses. The significance level was set at 95% (P <0.05). Results: The matches of series A had a greater number of interventions and greater hemodynamic load at the exact moment of the decision than those of series B. significantly (P <0.05): mean HR, HRmax, HRmin, Vmax, Cadencemed, and Cadencemax in series A were higher compared to series B. In the 15 seconds before the decisions: mean HR, HRmax, and HRmin in series A were higher than in series B, and Vmed in series B was higher in relation to series A. At the exact moment of the decisions: mean HR in series A was higher in relation to series B. Conclusion: Referees’ interventions are generally carried out under high hemodynamic pressure. The matches played in the A series require a higher number of interventions and hemodynamic intensity than the matches in the series B under high hemodynamic pressure, other psychological factors may play a role; however, this needs to be studied in greater depth.

Soccer is a sport play-able in various condition of environment, and one factor that affects this game is in heat situation, that can be one of key factor that change the match outcome. For the example is the big possibility that visiting team outside Arab countries gone to played at Gulf Region decreased winning possibility 3% for a increased 1°C temperature compared to the home team that easier to win under this circumstances. The home team had already aclimatized with the environment condition and often played in the heat temperature.Played soccer in the heat could increased sweat rate and peripheral vasodilation as a result to released the extra heat from the body, which affected dehidration phase and more metabolism to make more energy. In the elite level, pressure from the enviromental factors attracted the attention of both practitioners and the policy’s holders. In the Uni European Zone, match was usually played in the heat (example: at Madrid, Spain, at 30 degree of celcius). Temperature that exceeds 30 degree of celcius (maximum at 35 degree) for the example at the previous world cup 2014 Brazil could made the players got stressed because of the heat and got problems, one of them is decreased 3% of passing accuracy.

Abstract With the increasing popularization of football (soccer), new technologies have arrived in Brazil that assist in the maintenance of sports fields, making it possible to increase the quality of turfgrass in both professional and amateur fields. Thus, the revitalization process has become fundamental in sports fields installed with emerald grass to improve game performance and turfgrass development. The objective of this study was to revitalize an amateur sports field in the interior of São Paulo state, Brazil, planted with emerald grass. The conditions of the field were initially assessed and a set of revitalization procedures were carried out from November 2019 to March 2020 to improve turfgrass quality, including: chemical analysis of the soil and liming; mowing of the grass and disposal of clippings; soil decompaction through aeration with solid tines; application of sand (top dressing); pest and weed control; planting of new sod; fertilization and maintenance. Technical training with employees was also conducted for subsequent field maintenance. All tested operations were essential and necessary to improve the aesthetics and quality of the amateur sports field, so that the turfgrass could be revitalized and ready for use in soccer matches.

ABSTRACT Objective: To identify the incidence of injuries, their main characteristics, and the way they were managed throughout 2016 in two major series of a professional soccer championship in São Paulo, Brazil. Methods: This prospective study used an electronic questionnaire previously developed by the Medical Committee of the Paulista Soccer Federation which was sent to the team doctors after each match. Results: Two hundred and fifty-nine injuries occurred during 361 matches, and the incidence of injury per 1000 hours of game play was 21.32. Strikers were the most affected by injury; the most frequent diagnosis was muscle injury and the legs were predominantly affected. Most of the injuries occurred in the last 15 minutes of the first half and only 7.7% required surgical treatment. Conclusions: Muscle injuries were the most frequent, with most occurring in forwards and in the legs. Approximately half of the injuries occurred after contact and the vast majority was treated without surgery. MRI was the most requested exam and most injuries were classified as moderate (8 to 28 lost play days). Level of Evidence III, Study of Non Consecutive Patients; Without Consistently Applied Reference “Gold” Standard.

Study purpose. This study intended to convert the description of the strategies utilized in street soccer matches to international competitions. Materials and methods. Descriptive quantitative study was used that determined the participants by random sampling of the entire population. It acquired eight Indonesian national team athletes for the Homeless World Cup (HWC). The data was gathered from the six most important HWC matches, including those versus Zimbabwe, Israel, Romania, Brazil, Egypt, and the Netherlands, and examined using match footage. These six contests were chosen for their statistical analysis of decisive victories and defeats. Pearson Correlation was utilized for descriptive and inferential data analysis to evaluate the relationship between variables such as passing, shooting, goal, and goal allowed. Results. As indicated by the high association between passing and shooting accuracy and goal-scoring against the opponent’s goal, passing and shooting were dominating throughout street soccer matches, especially during big events such as the HWC. Conclusions. This study may serve as a resource for all teams in the globe as they develop and implement training program plans to prepare street soccer teams in their various nations.

In soccer stadiums, every aspect is important. Infrastructure, stands, changing rooms, artificial lighting and, without a doubt, the pitch, which is vital if matches are to run smoothly and without risk. One of the problems that reduces playability is water puddles, i.e. the waterlogging of the pitch caused by rainwater. This problem is common in Brazil due to the equatorial tropical climate, which is characterized by high temperatures and intense rainfall, the latter causing, in some situations, cancellations of matches with inconvenience to fans and spectators and even delays in championships. Another problem caused by excessive accumulated water is damage to the health of the grass, as poor drainage prevents the correct development of the root system due to the lack of oxygen in the soil, limiting the absorption of nutrients, which are important for the development of the grass, and making the grass maintenance and mowing process more difficult. Within this context, the drainage system on a soccer pitch is essential. This system is divided into surface and subsurface. Therefore, this paper presents and discusses the drainage system of the Bezerrão Stadium soccer field, located in the Administrative Region of Gama, Federal District.

In this paper the author will discuss the main inefficiencies in the 4 American major leagues of football (Argentina, Brazil, Mexico and USA), proposing a betting scheme, which outperforms the market with consistency over the past 9 Seasons (from 2012/2013 up to 2020/2021). Analysing the available data it was discovered how “Home advantage bias” and “Championship favourite advantage bias” play a big role in these championships and, by betting only on events, in which they were predicted favourable betting odds, it was possible to obtain an average return of +6.87% over 567 matches, using average bookmakers coefficients available on the market. The results are particularly significant, since, at least to our knowledge, there were no similar strategies available, which could guarantee such a big positive outcome for the leagues presented.

Urban seismology has gained scientific interest with the development of seismic ambient noise monitoring techniques and also for being a useful tool to connect society with the Earth sciences. The interpretation of the sources of seismic records generated by sporting events, traffic, or huge agglomerations arouses the population’s curiosity and opens up a range of possibilities for new applications of seismology, especially in the area of urban monitoring. In this contribution, we present the analysis of seismic records from a station in the city of Brasilia during unusual episodes of silencing and noisy periods. Usually, cultural noise is observed in high-fequency bands. We showed in our analysis that cultural noise can also be observed in the low-frequency band, when high-frequency signal is attenuated. As examples of noisy periods, we have that of the Soccer World Cup in Brazil in 2014, where changes in noise are related to celebrations of goals and the party held by FIFA in the city, and the political manifestations in the period of the Impeachment trial in 2016, which reached the concentration of about 300,000 protesters. The two most characteristic periods of seismic silence have been the quarantine due to the COVID-19 pandemic in 2020, and the trucker strike that occurred across the country in 2018, both drastically reducing the movement of people in the city.

ABSTRACT Objective: To analyze the images of alcohol in the rite of passage of adolescents of a quilombola community. Method: Qualitative and participatory study was developed by Creative and Sensitive Method, and guided by generated questions: “In my house, alcohol is...”; “Near my house, I see alcohol in...” Ten adolescents who live in a quilombola community in the north of the state of Espírito Santo, Brazil, participated in the group dynamics. The material was submitted to a thematic analysis. Results: Images of alcohol are common in the daily life of adolescents and can be seen in bars drinks, in their homes or in soccer fields; in different moments within the community (weekend barbecues, church celebrations, after soccer); and also in rites of passage, where adolescents first sipped or tasted alcohol with friends or socially with adults. Final Consideration: Alcohol in quilombola communities is cultural, and socially accepted, which turns it into a challenge for health professionals to promote health education with these adolescents.

A migração da música caipira, profundamente enraizada no mundo rural, para o meio urbano, no Brasil, deu origem à música sertaneja. Nos últimos anos, tem surgido uma nova variação deste gênero, o sertanejo universitário, voltado mais especificamente para um público jovem e caracterizado pela mistura melódica e pelo afastamento do cenário e dos valores da tradição rural. As temáticas exploram a importância do dinheiro para garantir conquistas sexuais, o universo das “baladas” (festas noturnas frequentadas pelos jovens), a sensualidade. Tais músicas têm alcançado um estrondoso sucesso de público no Brasil e no exterior. Entre seu público, e como propagandistas desse novo gênero musical, há celebridades do futebol (Neymar no Brasil, Cristiano Ronaldo em Portugal), cujo estilo de vida tem sintonia com as letras das músicas. Mais do que as características musicais do sertanejo universitário, procuramos refletir sobre aquilo que ele expressa enquanto quadro de valores e comportamentos de parcela da juventude contemporânea. The migration of caipira music, deeply rooted in rural areas, to urban areas in Brazil, has given rise to sertanejo music. In recent years, it has emerged a new variation of this rhythm, the sertanejo universitário, turned more specifically to a young public and characterized by melodic mix and a large removal of rural tradition scene and values. The themes explore the importance of money to ensure sexual conquests, the universe of "baladas" (evening parties attended by young people), sensuality. Such songs have been achieved a resounding success of public in Brazil and abroad. Among its audience, and as propagandists of this new musical genre, there are celebrities from soccer (Neymar in Brazil, Cristiano Ronaldo in Portugal), whose lifestyle has line with the lyrics. More than musical features of the sertanejo universitário, we try to reflect on what it expresses as a set of values and behaviors of a portion of contemporary youth.

Thiswork find to understand a propose methods and techniques to predict the ideal position of the soccer player, usingmachine learning algorithms. The database has more of one million of tuples. It was submitted to preprocessingstep, what is fundamental, because generated new features, removed incomplete and noisy data, generated anew balanced dataset and delete outliers, preparing the data to execution of the algorithms k-NN, decision trees,logistic regression, SVM and neural networks. With the purpose to understand the performance and accuracy,some scenarios were tested. There was poor results when executed multiclass problems. The best results comefrom binary problems. The models k-NN and SVM, specifically to this study, had the best accuracy. It is importantto note that SVM spent more than six hours to finish your execution, and k-NN used less than one and halfminute to end.
