Introduction The aging process causes structural and functional changes in the organism. Among these changes, the systems responsible for controlling the balance are also affected, especially in women. This study aims to perform an assessment and physiotherapy intervention in elderly with balance deficits through Berg scale and platform Wii Balance Board. Materials and methods The study was longitudinal quasi-experimental intervention. Held in the city of Passo Fundo, RS - Brazil. Participants were 38 elderly women who had a deficit balance. The instruments used to collect data was a questionnaire to identify, assess balance across the Berg Balance Scale and an intervention program with six games via the Wii Balance Board™ platform. To statistically analyze the effects before and after the intervention were used Wilcoxon and Pearson correlation, with a significance level of p = 0.05. Results In the present study, we observed a statistically significant improvement in the balance of elderly compared before and after intervention, moreover, the six games played also showed statistical significance when comparing the first and twentieth session, highlighting the games Tightrope Walk Table Tilt, Deep Breathing and Soccer Heading. Conclusion The evaluation and balance training with the platform Wii Balance Board were able to provide significant results for the elderly, besides, the game has the potential to treat the health, well-being and functional capacity of older people through the visual representation the game in real time.

PT. Este trabalho busca trazer uma reflexão acerca da importância da Placar para a construção do jornalismo esportivo no Brasil, fazendo uma sistematização das diferentes fases e seus distintos momentos. Mais longeva revista esportiva brasileira em circulação, o periódico completou, apesar da quase intermitente luta pela sobrevivência, meio século de vida em 2020. Como parte da mídia, também foi ao longo dos anos, de certo modo, um catalisador dos anseios e câmbios sociais e, por isso, esteve sempre em processo de mutação, descrevendo-os e, paralelamente, sendo influenciada pelos contextos das diferentes épocas. Tratamentos sexistas ao futebol de mulheres, como os de “musas” e “gostosas”, por exemplo, atravessaram fases históricas da revista, como as versões Placar Mais (1984), Placar Todos os Esportes (1988) e Futebol, Sexo & Rock and Roll (1995 a 1999). Com o advento do feminismo, esses termos não apenas ficaram para trás como a revista chegou a publicar em 2019 um pedido de desculpas pelo passado misógino e machista. O entrelaçamento histórico também pôde-se observar quando a revista deu voz a jogadores que não se furtavam a declarar seu posicionamento político (no contexto de efervescência em torno da redemocratização do país, nas chamadas “Diretas Já”) ou de discussões em torno da profissionalização do futebol nacional ou denúncias sobre corrupção no esporte. Neste estudo, evidencia-se a existência de uma linha tênue entre a história da sociedade brasileira e a história do futebol no país. Assim, a partir de entrevistas com sete jornalistas que fizeram parte de diferentes fases da revista (Celso Unzelte, Marcelo Duarte, Maurício Barros, Paulo Vinícius Coelho, Ricardo Corrêa, Sérgio Xavier Filho e o mais longínquo editor, Juca Kfouri), este artigo busca contribuir para a construção histórica de um capítulo relevante do entrelaçamento da cultura esportiva com a cultura social no Brasil através da Placar, uma peça fundamental da história do jornalismo esportivo nacional que se mantém viva.

EN. This article discusses the importance of Placar magazine in the construction of sports journalism in Brazil. It is based on the systematization of different phases of the magazine and the great moments of its history. Placar is the oldest Brazilian sports magazine published and celebrated its jubilee in 2020, after fifty years of a continuous struggle to ensure its existence.As an actor of the media sphere in Brazil, it has also been a catalyst of social yearnings and changes over the years. Therefore, it has always been in a process of mutation, describing them and, in parallel, being influenced by the social and political contexts. Sexism towards women in soccer, expressed by the use of terms such as "muses" or "hotties", is a part of the magazine’s history, more specifically during the time of Placar Mais (1984), Placar Todos os Esportes (1988) and Futebol, Sexo & Rock and Roll (1995 to 1999). With the rise of feminist movements, these terms were discarded, and the magazine took a stand in 2019 by apologizing for the misogynistic and sexist content published in the past. Content imbued with historical momentums also appears at times when the magazine features players who voice political opinions (for instance during the effervescence of the context of redemocratization, at the time of the first direct elections after the fall of the military dictatorship, the so-called "Diretas Já") or share opinions on the professionalization of Brazilian soccer and the corruption operating within the sport’s institutions. The study highlights how fine is the line between the history of Brazilian society and the history of Brazilian soccer. Based on interviews with seven journalists who contributed to the magazine during different phases of its existence (Celso Unzelte, Marcelo Duarte, Maurício Barros, Paulo Vinícius Coelho, Ricardo Corrêa, Sérgio Xavier Filho and the veteran editor, Juca Kfouri), the article contributes to the historical construction of an important testimony of the intertwining of sports and social history in Brazil. This relationship is illustrated through the history of Placar, shown as a contemporary and central player in the history of Brazilian sports journalism.

FR. Cet article propose une réflexion sur l'importance du magazine Placar dans la construction du journalisme sportif au Brésil, à partir d’une systématisation de ses différentes phases et des grands moments de son histoire. Premier magazine sportif brésilien, Placar a fêté son jubilé en 2020, après cinquante années marquées par un combat continuel pour assurer son existence. En tant qu’acteur du monde médiatique brésilien durant toutes ces années, il représente un catalyseur des aspirations et des changements sociaux. Si, d’un côté, il décrit les contextes des différentes époques du pays, il en subit simultanément l’influence, ce qui explique ses constantes mutations. Le sexisme à l’égard du football féminin, énoncé par des termes tels que « muses » ou « bombasses », a ainsi marqué l’histoire du magazine, dans ses versions Placar Mais (1984), Placar Todos os Esportes (1988) et Futebol, Sexo & Rock and Roll (1995 à 1999). Avec l'avènement du féminisme, ces termes ont non seulement été écartés, mais le magazine a été jusqu’à publier, en 2019, des excuses pour son passé misogyne et sexiste. Cette imbrication historique s’observe également lorsque le magazine donne la parole à des joueurs qui n’hésitent pas à donner leurs opinions, qu’elles soient politiques (dans le contexte effervescent de la redémocratisation du pays, au moment des premières élections directes après la dictature militaire, les « Diretas Já ») ou dans le cadre des discussions autour de la professionnalisation du football brésilien et de la corruption dans le sport. Cette étude montre que seule une frontière ténue sépare l'histoire de la société brésilienne de celle de son football. À partir d'entretiens avec sept journalistes qui ont marqué les différentes phases du magazine (Celso Unzelte, Marcelo Duarte, Maurício Barros, Paulo Vinícius Coelho, Ricardo Corrêa, Sérgio Xavier Filho et le vétéran des rédacteurs, Juca Kfouri), cet article contribue à la construction historique d'un chapitre important de l'entrelacement de la culture sportive et sociale au Brésil. Cette relation est ici mise en perspective à partir du magazine sportif Placar, personnage toujours vivant et fondamental de l'histoire du journalisme sportif brésilien.

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

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.

Full textAbstract:
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.

Full textAbstract:
Background Female collegiate athletes have been reported to have a higher rate of anterior cruciate ligament injury compared to male collegiate athletes. This finding has spawned a branch of research focused on understanding and preventing this injury pattern. Purpose To determine if the trends reported in 1994 have continued. Study Type Descriptive epidemiology study. Methods The National Collegiate Athletic Association Injury Surveillance System database was reviewed for all data relating to men's and women's basketball and soccer anterior cruciate ligament injuries for 1990 to 2002. Results No significant difference was seen in basketball comparing frequency of contact versus noncontact injuries between men (70.1%) and women (75.7%). Male basketball players sustained 37 contact injuries and 78 noncontact injuries. Female basketball players sustained 100 contact injuries and 305 noncontact injuries. In soccer, there was a significant difference in frequency of injury for male (49.6%) and female (58.3%) athletes when comparing contact and noncontact injuries (χ2 = 4.1, P <. 05). Male soccer players sustained 72 contact injuries and 66 noncontact injuries. Female soccer players sustained 115 contact injuries and 161 noncontact injuries. The magnitude of the difference in injury rates between male and female basketball players (0.32-0.21, P =. 93) remained constant, whereas the magnitude of the difference in the rate of injuries between male and female soccer players (0.16-0.21, P =. 08) widened. Comparing injury within gender by sport, soccer players consistently sustained more anterior cruciate ligament injuries than did basketball players. The rate of anterior cruciate ligament injury for male soccer players was 0.11 compared to 0.08 for male basketball players (P =. 002). The rate of anterior cruciate ligament injury for female soccer players was 0.33 and for female basketball players was 0.29 (P =. 04). The rates for all anterior cruciate ligament injuries for women were statistically significantly higher (P <. 01) than the rates for all anterior cruciate ligament injuries for men, regardless of the sport. In soccer, the rate of all anterior cruciate ligament injuries across the 13 years for male soccer players significantly decreased (P =. 02), whereas it remained constant for female players. Conclusions In this sample, the rate of anterior cruciate ligament injury, regardless of mechanism of injury, continues to be significantly higher for female collegiate athletes than for male collegiate athletes in both soccer and basketball. Clinical Relevance Despite vast attention to the discrepancy between anterior cruciate ligament injury rates between men and women, these differences continue to exist in collegiate basketball and soccer players. Also demonstrated is that although the rate of injury for women is higher than for men, the actual rate of injury remains low and should not be a deterrent to participation in sports.

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.

Overall, the essay is mainly about the women’s soccer games due to nowadays people’s over-widening interests about women’s soccer games and women’s World Cup. I focused on basically three prospectives of women’s soccer games and especially focused on the disparity between women’s soccer games and men’s game.There is huge disparity between male players’ salary and female players’ salary, there is also huge difference of public acceptance about women’s soccer game and men’s soccer games(especially the different reasons which drove audiences watch the game)In addition, the investments of women soccer clubs is fortunately increasing in China mainly because the government support and more and more companies already realized the huge market behind women’s soccer game as well.

Full textAbstract:
The relative age effect (RAE) is characterised by an overrepresentation of athletes born earlier in the selection year. Whilst an RAE is consistently evident in male soccer, examinations in female players remain limited. The aim of the present study was to examine the influence of sex, as well as age, success, and playing status in European soccer players. The sample consisted of a total of 6546 soccer players from 55 soccer nations that competed in recent European Championship qualification campaigns. Results indicated an evident RAE in male [p = 0.017] but not female [p = 0.765] players. Male players were over-represented by players born in the first quartile for the U17 [p < 0.001] and U19 [p = 0.001] levels, however, this over-representation did not transfer to senior levels. No RAE was observed at any level for female players. Inside each age group, a slight selection bias towards those born in the first quartile for successful squads was observed but did not significantly differentiate between qualification status for either male or female players. Results from this study highlight the disparity in RAE prevalence between male and female players and raise further questions regarding the value of selecting relatively older players to metrics of success, transition, and selection for senior international soccer.

Performance in soccer has been associated with specific morphological characteristics. Few studies have simultaneously compared the relationships between physical fitness and body composition in both sexes. This study aimed (i) to analyze the differences in anthropometric parameters, body composition, and physical fitness between sexes and playing position in soccer players and (ii) to determine the relationship among anthropometric and body composition parameters to physical fitness parameters according to sex. A total of 50 soccer players (men: n = 26; women: n = 24), participated in the study. Assessments of nutritional intake, anthropometry, body composition, and physical fitness (isometric strength, maximal aerobic capacity, and vertical jump) were carried out. Differences between sexes were observed in all anthropometric and body composition parameters (p < 0.001). There were differences between midfielders and forwards in fat percentage (p < 0.05). Regarding physical condition, differences were found between sexes in all tests performed (p < 0.001). In men soccer players, there were significant correlations between body composition and aerobic capacity (p < 0.05), while in women soccer players, there were correlations with isometric strength tests (p < 0.05). Anthropometry, body composition, and physical fitness differed between sexes. Fat percentages were different among playing positions. There were relationships between anthropometry and body composition with physical fitness. Knowledge of anthropometric and fitness characteristics by playing position and gender in soccer players could help develop specific training programs.

Full textAbstract:
The objective of the study was to determine the prevalence of iron deficiency and iron deficiency anemia among elite women soccer players. Hemoglobin, serum iron, serum total iron binding capacity, and ferritin were determined in 28 female soccer players called up for the national team. Of the investigated female soccer players, 57% had iron deficiency and 29% iron deficiency anemia 6 months before the FIFA Women’s World Cup. It is concluded that iron deficiency and iron deficiency anemia is common in female soccer players at the top international level. Some might suffer from relative anemia and measurement of hemoglobin alone is not sufficient to reveal relative anemia. Regular monitoring of hemoglobin concentration and iron status is necessary to institute iron supplementation when indicated.

The purpose of this study was to analyze the characteristics of injuries in female national soccer players. The injuries data were recorded by Korea Football Association medical staff using the Daily Medical Report provided by the Asian Football Confederation during a total 21 training camps and friendly and official matches from January 2014 to December 2018. A total of 483 players in the national team training camps and matches participated in the study, of which 377 players experienced more than one injury. Sports injuries accounted for 89% of the total 1,019 injuries; general diseases accounted for the remaining 11%. The number of injuries per 1,000 exposure hours was higher in matches than in training sessions. Most injuries that occurred during training and matches involved the lower extremities (79%). The most common injury diagnosed during training and matches was muscle rigidity (45%), followed by contusions/hematomas/bruises (22%) and sprain (15%). The largest proportions of injuries in terms of absence from soccer play were minimal injury (67%), followed by mild (29%), moderate (3.5%), and severe (1%). As conclusion, the characteristics of injuries during training sessions and matches were different. Rehabilitation and injury prevention programs need to developed for female soccer players to improve the players’ performance.

Purpose: To compare the sprint mechanical force–velocity (F–V) profile between soccer and futsal players. A secondary aim was, within each sport, to study the differences in sprint mechanical F–V profile between sexes and players of different levels. Methods: A total of 102 soccer players (63 men) and 77 futsal players (49 men) who were competing from the elite to amateur levels in the Spanish league participated in this investigation. The testing procedure consisted of 3 unloaded maximal 40-m sprints. The velocity–time data recorded by a radar device were used to calculate the variables of the sprint acceleration F–V profile (maximal theoretical force [F0], maximal theoretical velocity [V0], maximal power [Pmax], decrease in the ratio of horizontal to resultant force [DRF], and maximal ratio of horizontal to resultant force [RFpeak]). Results: Futsal players showed a higher F0 than soccer players (effect size [ES] range: 0.11–0.74), while V0 (ES range: −0.48 to −1.15) and DRF (ES range: −0.75 to −1.45) was higher for soccer players. No significant differences were observed between soccer and futsal players for Pmax (ES range: −0.43 to 0.19) and RFpeak (ES range: −0.49 to 0.30). Men and high-level players presented an overall enhanced F–V profile compared with women and their lower-level counterparts, respectively. Conclusions: The higher F0 and lower V0 of futsal players could be caused by the game’s specific demands (larger number of accelerations but over shorter distances than in soccer). These results show that the sprint mechanical F–V profile is able to distinguish between soccer and futsal players.

Full textAbstract:
A unique aspect of soccer is the use of the head for directing the ball. The potential for resultant head injuries has been the focus of discussions worldwide. Prior work has attributed neuropsychologic deficits to the cumulative effects of heading, without evaluating concussion rates in soccer players. We prospectively studied the seven men's and eight women's varsity soccer teams in the Atlantic Coast Conference during two seasons to document concussion incidence. The 29 concussions diagnosed over the 2 years in 26 athletes, 17 (59%) concussions in men and 12 (41%) in women, resulted from contact with an opponent's head (8, 28%), elbow (4, 14%), knee (1, 3%), or foot (1, 3%); the ball (7, 24%); the ground (3, 10%); concrete sidelines (1, 3%); goalpost (1, 3%); or a combination of objects (3, 10%). Twenty concussions (69%) occurred in games; none resulted from intentional heading of the ball. The basic incidence was 0.96 concussions per team per season. The overall incidence was 0.6 per 1000 athlete-exposures for men, and 0.4 per 1000 athlete-exposures for women. By concussion grade, there were 21 (72%) grade 1, 8 (28%) grade 2, and no grade 3 concussions. These findings suggest that concussions are more common in soccer than anticipated and that acute head injuries may have potential for long-term neuropsychologic changes.

Full textAbstract:
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.

Full textAbstract:
Background: It has been shown that anterior cruciate ligament (ACL) injuries are more prevalent in female athletes than in male athletes. Soccer and basketball are considered high-risk sports for ACL injury in female athletes. Several studies have reported a relationship between ACL injury and measures of foot structure. This study was conducted to investigate the relationship between foot structure and ACL injury rates in female and male soccer and basketball players. Methods: One hundred five soccer and basketball players (53 women and 52 men) were recruited and divided into an ACL-normal group (n = 89) and an ACL-injured group (n = 16). Two measures of foot structure (subtalar joint neutral position and navicular drop test values) were recorded for each subject. An independent t test and a paired t test were used to analyze differences in ACL status, foot structure, and sex. A χ2 analysis determined whether the prevalence of ACL injury was independent of sport. Results: No statistically significant differences were found in the foot structure measures between women and men. Female soccer and basketball players had an ACL injury rate seven times that of male players. Conclusions: Values derived from subtalar joint neutral position measurement and the navicular drop test were not associated with ACL injury in collegiate female and male soccer and basketball players.

Abstract Context: Researchers have indicated that female soccer players may be at greater risk of concussion compared with their male counterparts. Soccer headgear is marketed for reducing head acceleration and risk of concussion. Objective: To determine the effect of sex and soccer headgear on head impact kinematics and dynamic stabilization during soccer heading. Design: Cross-sectional design. Setting: Research laboratory. Patients or Other Participants: Forty-four college-aged soccer players (29 women, 15 men). Intervention(s): Using a head impact model, participants performed 4 soccer headers under 3 headgear conditions (control, Head Blast Soccer Band, and Full90 Select Performance Headguard). Main Outcome Measure(s): Dependent variables assessed before soccer heading were head-neck anthropometrics and isometric neck muscle strength, and those assessed during soccer headers were resultant linear head acceleration, Head Injury Criteria (HIC36), and superficial neck muscle electromyography. Statistical analyses included multivariate and univariate analyses of variance with repeated measures, independent-samples t tests, appropriate follow-up analyses of variance and post hoc t tests, and Pearson product moment correlations (α = .05). Results: Head acceleration in women was 32% and 44% greater than in men when wearing the Head Blast (21.5 g versus 16.3 g) and Full90 Select (21.8 g versus 15.2 g), respectively (P < .05). Compared with men, women exhibited 10% greater head accelerations (20.2 g versus 18.2 g) during the control condition (P = .164). Conclusions: Female soccer players exhibited greater head accelerations than their male counterparts when wearing headgear. Our results are important clinically because they indicate that soccer headgear may not be an appropriate head injury prevention tool for all athletes.

Full textAbstract:
Soccer is one of the most popular sports in the world. As its number of players is increasing, the number of female players is also on the rise. However, there are limited data about how the diets of female soccer players should be designed. Thus, the aim of our work is to deliver concise nutritional recommendations for women practicing this sport. Based on a literature review, we emphasize that individual adjustment of the energy value of the diet is the key factor for the physical performance of female soccer players. Appropriate macronutrient intake makes it possible to achieve the proper energy value of the diet (5–10 g/kg body mass/day carbohydrates; 1.2–1.7 g/kg body mass/day proteins; <30% fats from energy). The micronutrients should be consumed in amounts corresponding to individual values recommended in national standards. Soccer players should pay special attention to the proper consumption of such micronutrients, as well as vitamins such as iron, calcium, and vitamin D. The right amount of fluid intake, consistent with the player’s needs, is crucial in maximizing exercise performance. The diet of a female practicing soccer is usually characterized with low energy values, which increases the risk of various health consequences related to low energy availability. Monitoring the diets of female soccer players is, therefore, necessary.

ABSTRACT Introduction: Ergospirometry is a noninvasive procedure used to assess physical performance or the capacity of an individual, through an analysis of expired gases and respiratory variables. This procedure is crucially important in sports, and makes a significant contribution to the measurement of cardiorespiratory fitness indices, such as maximal oxygen consumption (VO2 max) and the anaerobic threshold (AT). Objective: To assess aerobic capacity and potency in professional and junior soccer players, handball athletes, and women soccer players. Methods: Forty-eight athletes participated voluntarily and were divided into 4 groups. The first group consisted of 12 youth soccer players in the under-20 category, the second group was made up of 12 professional soccer players, the third group was made up of female soccer players, and the fourth group consisted of handball players. Results: We analyzed values such as peak VO2, average speed and heart rate at the anaerobic threshold as well as pulmonary ventilation. We found that the values were always greater for the group formed by professional soccer players, with the exception of mean maximum O2 consumption, in which the difference between this group and that of soccer players in the junior category was not significant. In other physical valences, there was a degree of similarity between the other groups, with special emphasis on pulmonary ventilation, which was significantly lower in the group of female soccer players. Conclusion: The particularities of each sport, such as pitch dimensions, duration, and tactical system, together with the morphology and sex of the athletes, directly influence peak VO2, AT and VE values in athletes who play different sports.

Full textAbstract:
The present study aimed to evaluate the effects of a match lost and a match won on post-competitive heart rate variability (HRV) in semi-professional female soccer athletes. A total of 13 players, with a mean age of 23.75 (5.32), from the Cáceres Women Football Club of the Spanish Second National Division participated in our study. They were evaluated in two microcycles which correspond to a match lost and a match won. For each microcycle, baseline and post-competitive measures were collected. Results indicate that HRV was significantly reduced before a match lost and won. Significant differences in HRV variables were observed when compared the lost match, and the match won. Results highlight the importance and usefulness of analyzing the HRV as an indicator of post-competitive fatigue in semiprofessional soccer players. Therefore, a competition’s results could be considered a relevant variable to consider when programming training load.

This study aimed to analyze anthropometric and body composition effects in professional soccer women players across the early and mid-competitive 2019/20 season. Seventeen players (age, height, body mass, and body mass index of 22.7 ± 6.3 years, 167.5 ± 5.6 cm, 60.7 ± 6.6 kg and 21.6 ± 0.2 kg/m2) from a Portuguese BPI League team participated in this study. The participants completed ≥80% of 57 training sessions and 13 matches. They were assessed at three points (before the start of the season (A1), after two months (A2), and after four months (A3)) using the following variables: body fat mass (BFM), soft lean mass (SLM), fat-free mass (FFM), intracellular water (ICW), extracellular water (ECW), total body water (TBW), and phase angle (PhA, 50 Khz), through InBody S10. Nutritional intake was determined through a questionnaire. Repeated measures ANCOVA and effect sizes (ES) were used with p < 0.05. The main results occurred between A1 and A2 for BFM (−21.7%, ES = 1.58), SLM (3.7%, ES = 1.24), FFM (4%, ES = 1.34), ICW (4.2%, ES = 1.41), TBW (3.7%, ES = 1.04). Furthermore, there were significant results between A1 and A3 for FFM (4.8%, ES = 1.51), ICW (5%, ES = 1.68), and PhA (10.4%, ES = 6.64). The results showed that the water parameters improved over time, which led to healthy hydration statuses. The training load structure provided sufficient stimulus for appropriate physical fitness development, without causing negative disturbances in the water compartments.

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.

Context Among US collegiate soccer players, the incidence rate and the event characteristics of hamstrings strains differ between sexes, but comparisons in the return-to-participation (RTP) time have not been reported. Objective To compare the RTP time between male and female collegiate soccer players and analyze the influence of event characteristics on the RTP time for each sex. Design Descriptive epidemiology study. Setting Data were collected from collegiate teams that voluntarily participated in the National Collegiate Athletic Association Injury Surveillance System. Patients or Other Participants Collegiate soccer athletes who sustained 507 hamstrings strains (306 men, 201 women) during the 2004 through 2009 fall seasons. Main Outcome Measure(s) Nonparametric statistics were used to evaluate RTP time differences between sexes and among categories of each event characteristic (ie, time of season, practice or competition, player position). Negative binomial regression was used to model the RTP time for each sex. All analyses were performed separately for first-time and recurrent strains. Results We found no differences in the RTP time between sexes for first-time (median: men = 7.0 days, women = 6.0 days; P = .07) or recurrent (median: men = 11 days, women = 5.5 days; P = .06) hamstrings strains. For male players with first-time strains, RTP time was increased when the strain occurred during competition or the in-season/postseason and varied depending on the division of play. Among female players with first-time strains, we found no differences in RTP time within characteristics. For male players with recurrent hamstrings strains, the RTP time was longer when the injury occurred during the in-season/postseason. Among female players with recurrent strains, RTP time was longer for forwards than for midfielders or defenders. Conclusions Although we found no differences in the RTP time after hamstrings strains in male and female collegiate soccer players, each sex had unique event characteristics that influenced RTP time.

This study aims to evaluate the relation between salivary concentrations of cortisol (C), testosterone (T), the ratio T:C and the individual performance of top-level female soccer athletes during official matches. Eighteen female athletes from a national soccer team (age 23.06 ± 4.33 years) participated in the study. Four official matches were analysed and the on-field time of each player as well as the index of individual effectiveness were calculated. Players were classified in two clusters according to their individual performance (cluster 1 – poor individual performance; cluster 2 – good individual performance) using K-means and their hormonal variables were compared. The players of cluster 2 generally revealed higher values (p˂.05) in both the positive actions and individual effectiveness, when compared with the players of cluster 1. The players of both clusters presented identical values of C, T and T:C at the four evaluated matches. The athletes of cluster 2 showed a significant increase in C (p˂.05) and a significant decrease in T and T:C before the games lost (M2 and M5). However, there was no linear relation between the variation of both hormones during the matches and the individual performance of players. Performance in competition revealed significant differences between players, though with no apparent relation to the hormonal kinetics of C and T before and after the matches.

Full textAbstract:
This study aimed to explore the main determinants of repeated-sprint ability (RSA) in women soccer players considering aerobic capacity, sprinting performance, change-of-direction, vertical height jump, and hip adductor/abductor isometric strength. Twenty-two women soccer players from the same team participating in the first Portuguese league were observed. Fitness assessments were performed three times during a 22-week cohort period. The following assessments were made: (i) hip abductor and adductor strength, (ii) squat and countermovement jump (height), (iii) change-of-direction test, (iv) linear sprinting at 10- and 30-m, (v) RSA test, and (vi) Yo-Yo intermittent recovery test level 1. Positive moderate correlations were found between peak minimum RSA and adductor and abductor strength (r = 0.51, p < 0.02 and r = 0.54, p < 0.01, respectively). Positive moderate correlations were also found between peak maximum RSA and adductor and abductor strength (r = 0.55, p < 0.02 and r = 0.46, p < 0.01, respectively). Lastly, a moderate negative correlation was found between fatigue index in RSA and YYIR1 test performance (r = −0.62, p < 0.004). In conclusion, abductor and adductor isometric strength-based coadjutant training programs, together with a high degree of aerobic endurance, may be suitable for inducing RSA in female soccer players.

Background: Radiographic features of femoroacetabular impingement (FAI) are prevalent in kicking athletes, especially soccer players. However, there remains a paucity of data on the characteristics of symptomatic soccer players with an established diagnosis of FAI. Purpose: To report on patient demographics, injury, and clinical and radiographic characteristics in a large cohort of soccer players who underwent primary hip arthroscopy for FAI and to perform a sex- and competition level–specific analysis of these data. Study Design: Cross-sectional study; Level of evidence, 3. Methods: An institutional hip preservation registry containing 3318 consecutive primary hip arthroscopies for FAI performed between March 2010 and January 2016 was retrospectively reviewed for patients identified as soccer players. Patient demographics, injury characteristics, and clinical and radiographic findings were recorded, and sex- and competition level–specific differences were analyzed. Results: A total of 421 hips (336 soccer players) were identified, including 257 (61.0%) men and 164 (39.0%) women. Of these, 105 (24.9%) were reported as highly competitive, 194 (46.1%) as competitive, 75 (17.8%) as recreational, and 47 (11.2%) did not report a level. The majority of the 336 soccer players (231 hips; 55%) reported chronic hip pain lasting >6 months with no acute injury at the initial visit. Alpha angle, coronal center-edge angle, and femoral version on computed tomography scan measured 64.5°± 12°, 32.3°± 9°, and 13.7°± 10° (mean ± SD), respectively. There were 230 (55%) hips with a type 2 anterior inferior iliac spine (AIIS), 78 (18.5%) with a type 1 AIIS, and 19 (4.5%) with a type 3 AIIS. When compared with male athletes, female athletes had more hip internal rotation on physical examination (14.9° vs 8°; P < .001), lower alpha angles (57.5° vs 68.5°; P < .001), and lower-grade AIIS morphology ( P = .003). Acute injury as the reason for hip symptoms was most likely in the highly competitive group ( P < .001). Conclusion: Female soccer players were more likely to have less severe clinical and radiographic findings than were male soccer players. Acute injury as the cause of hip symptoms was more common in highly competitive players. Clinical Relevance: Focusing on soccer players with an established FAI diagnosis, the findings of this study suggest that there are sex- and competition level–based differences in the presentation, physical examination, and imaging characteristics among the players. These findings can better guide clinicians in the diagnostic evaluation of symptomatic soccer players with FAI and in tailoring treatment recommendations to specific cohorts.

Research describing the match and specific positional demands during match play in women’s collegiate soccer is limited. The purpose of the study was to quantify the match demands of National Collegiate Athletic Association (NCAA) Division III soccer and assess position differences in movement kinematics, heart rate (HR), and energy expenditure. Twenty-five Division III women soccer players (height: 1.61 ± 0.3 m; body mass: 66.7 ± 7.5 kg; fat-free mass: 50.3 ± 6.5 kg; body fat%: 25.6 ± 5.1%) were equipped with a wearable global positioning system to assess the demands of 22 matches throughout a season. Players were categorized by position (goal keepers (GK), center defenders (CB), flank players (FP), forwards (F), and center midfielders (CM)). Players covered 9807 ± 2588 m and 1019 ± 552 m at high speeds (>249.6 m·m−1), with an overall average speed of 62.85 ± 14.7 m·m−1. This resulted in a mean HR of 74.2 ± 6% HR max and energy expenditure of 1259 ± 309 kcal. Significant and meaningful differences in movement kinematics were observed across position groups. CM covered the most distance resulting in the highest training load. FP covered the most distance at high speeds and mean HR values were highest in CM, CB, and FP positions.

Full textAbstract:
A unique feature of soccer is the purposeful use of the head for controlling, passing, and shooting a soccer ball. Some concern has been expressed in the literature on the cumulative effects of heading on soccer players. Certain neurophysiologic and neuropsychologic changes have been reported in current or retired players, with heading being blamed. A major factor that could influence some of the findings is a player's history of concussive episodes, which are known to influence brain function. These episodes can occur during aspects of the game other than heading. We interviewed all male and female soccer players (N 137, average age 20.5 years) who competed at the U.S. Olympic Sports Festival in 1993. The mechanisms of injuries, frequency, and sequelae were determined. There were 74 concussions in 39 male players (grade I 50) and 28 concussions in 23 female players (grade I 19). For the men, 48 of the 74 episodes were from collisions with another player. For the women, 20 of 28 were from such collisions. Headaches, being “dazed,” and dizziness were the most common symptoms reported. Based on concussion history, the odds are 50% that a man, and 22% that a woman, will sustain a concussion within a 10-year period. The data indicate that concussions from player-to-player contact are a frequent hazard in soccer. Head injuries incurred this way may be more of an influence for published findings of physiologic and psychologic deficiencies than routine heading of the soccer ball.

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.

Full textAbstract:
Arguably, girls’ and women’s soccer in England is currently experiencing amelioration in terms of participation numbers, media coverage and general public interest. Although, lurking behind these favorable statistics and the pretence of new developmental strategies sits soccer’s cultural millstone, weighing down social progression and limiting the credibility afforded to the game. This paper seeks to unearth how girls and women negotiate their experiences of playing against this backdrop of inferiority by giving them a ‘voice’. The study is explored through a lens of ‘performative pleasure’ as a theoretical standpoint for understanding the basis of activity which involved qualitative methods enagaging with 57 female players aged between 8 and 31 years. The examination uncovered that despite barriers to participation and the management of social stereotyping, girls and women found pleasure through playing. Soccer provided the players with a ‘safe space’ to experience leisure, but ironically this refuge was often needed in response to soccer-based teasing and ‘banter’: conceptualized as the Sanctuary Paradox. The current findings have implications for the management and execution of cultural change within sporting environments.

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.

This study aimed to analyze the variations of fitness status, as well as test the relationships between accumulated training load and fitness changes in women soccer players. This study followed an observational analytic cohort design. Observations were conducted over 23 consecutive weeks (from the preseason to the midseason). Twenty-two women soccer players from the same first Portuguese league team (22.7 ± 5.21 years old) took part in the study. The fitness assessment included anthropometry, hip adductor and abductor strength, vertical jump, change of direction, linear speed, repeated sprint ability, and the Yo-Yo intermittent recovery test. The training load was monitored daily using session rating of perceived exertion (s-RPE). A one-way repeated ANOVA revealed no significant differences for any of the variables analyzed across the three moments of fitness assessments (p > 0.05). The t-test also revealed no differences in the training load across the moments of the season (t = 1.216; p = 0.235). No significant correlations were found between fitness levels and accumulated training load (range: r = 0.023 to −0.447; p > 0.05). This study revealed no differences in the fitness status during the analyzed season, and the fitness status had no significant relationship with accumulated training load.

The professional soccer is always changing and is constantly searching tools and data to help the decision-making,providing tactics and techniques to the team. In Brazil, this sport goes to same way and the investments areconsiderable. The One Sports is a company that capture GPS data from professional soccer players of someBrazilian teams. This set of data has a lot of features and the One Sports asked if was possible to predict the idealposition of a player. Then, was firmed a cooperation between a academic study and a commercial company. 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.

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.

Full textAbstract:
The questions asked in this paper are: what is it that women who participate in recreational sport appreciate most or enjoy most about their sports? What are the differences and similarities among women who participate in aerobics, tennis or soccer? Thirty one Norwegian women (ages 19 to 36 years) participated in the study. The research method used was qualitative interviews. The music and the rhythm were mentioned most often by the women practicing aerobics. The availability of the sport was a major factor for the tennis players. These were in contrast to the soccer players for whom the social aspect of the sport dominated. A theme that occurred across the different sports was related to physicality and to the use of the body. It is clear from the data that the women found that being physically active was positive and pleasurable, and that some of the findings challenge the norms of female physicality.

Full textAbstract:
Objective:To determine the rate and differential contribution of heading vs unintentional head impacts (e.g., head to head, goal post) to CNS symptoms in adult amateur soccer players.Methods:Amateur soccer players completed baseline and serial on-line 2-week recall questionnaires (HeadCount) and reported (1) soccer practice and games, (2) heading and unintentional soccer head trauma, and (3) frequency and severity (mild to very severe) of CNS symptoms. For analysis, CNS symptoms were affirmed if one or more moderate, severe, or very severe episodes were reported in a 2-week period. Repeated measures logistic regression was used to assess if 2-week heading exposure (i.e., 4 quartiles) or unintentional head impacts (i.e., 0, 1, 2+) were associated with CNS symptoms.Results:A total of 222 soccer players (79% male) completed 470 HeadCount questionnaires. Mean (median) heading/2 weeks was 44 (18) for men and 27 (9.5) for women. One or more unintentional head impacts were reported by 37% of men and 43% of women. Heading-related symptoms were reported in 20% (93 out of 470) of the HeadCounts. Heading in the highest quartile was significantly associated with CNS symptoms (odds ratio [OR] 3.17, 95% confidence interval [CI] 1.57–6.37) when controlling for unintentional exposure. Those with 2+ unintentional exposures were at increased risk for CNS symptoms (OR 6.09, 95% CI 3.33–11.17) as were those with a single exposure (OR 2.98, 95% CI 1.69–5.26) when controlling for heading.Conclusions:Intentional (i.e., heading) and unintentional head impacts are each independently associated with moderate to very severe CNS symptoms.

Full textAbstract:
Purpose:The purpose of this study was to compare the session-RPE method for quantifying internal training load (TL) with various HR-based TL quantification methods in a variety of training modes with women soccer players.Methods:Fifteen elite women soccer players took part in the study (age: 19.3 ± 2.0 y and VO2max: 50.8 ± 2.7 mL·kg−1·min−1). Session-RPE, heart rate, and duration were recorded for 735 individual training sessions and matches over a period of 16 wk. Correlation analysis was used to compare session-RPE TLs with three commonly used HR-based methods for assessing TL.Results:The mean correlation for session-RPE TL with Banister’s TRIMP, LTzone TL and Edwards’s TL were (r = 0.84, 0.83, and 0.85, all P < .01, respectively). Correlations for session-RPE TL and three HR-based methods separated by session type were all significant (all P < .05). The strongest correlations were reported for technical (r = 0.68 to 0.82), conditioning (r = 0.60 to 0.79), and speed sessions (r = 0.61 to 0.79).Conclusion:The session-RPE TL showed a significant correlation with all training types common to soccer. Higher correlations were found with less intermittent, aerobic-based training sessions and suggest that HR-based TLs relate better to session-RPE TLs in less intermittent training activities. These results support previous findings showing that the session-RPE TL compares favorably with HR-based methods for quantifying internal TL in a variety of soccer training activities.

Full textAbstract:
Although asymmetries in lower limbs have been linked with players’ performance in male soccer players, literature that has been published addressing female soccer is scarce. Thus, the aim of this study was twofold: (i) describe the asymmetries of women soccer players during jumping, change-of-direction and range-of-motion tests; and (ii) test possible relationships between asymmetries and injury risk in female soccer players. Sixteen female players (15.5 ± 1.5 years) performed a battery of fitness tests (i.e., jump ability, change-of-direction ability and passive range-of-motion) and muscle mass analysis via dual-energy X-ray absorptiometry, through which the specific asymmetry index and the related injury risk were calculated. Significant (p < 0.05) lower asymmetries in the change-of-direction test were observed in comparison to those observed in jumping and range-of-motion tests; significant (p < 0.05) lower asymmetries in muscle mass were also reported compared to those found in the change-of-direction and countermovement jump tests. Additionally, increased injury risk for countermovement jump and hip flexion with extended knee range-of-motion (relating to asymmetry values) and for ankle flexion with flexed knee range-of-motion in both legs (relating to reference range-of-motion values), as well as increased individual injury risk values, were observed across all tests. These findings suggest the necessity to implement individual approaches for asymmetry and injury risk analyses.
