RESUMEN

We investigated whether the application of photobiomodulation therapy (PBMT) immediately after a standardized warm-up (WU + PBMT) or traditional PBMT (no pre-warming) would influence performance in intermittent testing and intensity variables. In a counterbalanced randomized crossover design, twelve female futsal players (mean age: 23.9 ± 3.8 years) attended four sessions. Each session involved either a standardized warm-up or maintaining seated rest for five minutes. Subsequently, PBMT or placebo (with the PBMT device turned off) was applied, followed by the YoYo Intermittent Recovery Level 1 test (YYIR1) during which we assessed heart rate, rating of perceived exertion, and blood lactate levels. The performance in YYIIR1 was superior (p = 0.02) in the WU + PBMT condition (440.0 ± 59.0 m) compared to the WU + Placebo (353.3 ± 94.7 m), and placebo alone (no warm-up) (325.0 ± 67.2 m). We conclude that a combination of a specific warm-up before PBMT application improves high-intensity intermittent performance in amateur female futsal players without affecting intensity variables.

RESUMEN

Soccer players' ability to make efficient and quick decisions has gained more importance due to the increase in game speed in the last few years. Therefore, this study aimed to examine the relationship between the engagement in previous developmental activities in soccer and futsal with the quality and speed of decision-making skills in different phases of sport development of elite female soccer players. The sample comprised 77 elite Brazilian professional female soccer players. Players' decision-making skills were assessed based on an objective video-based test - TacticUP®. We used a retrospective questionnaire to collect information about previous participation in different developmental activities. The results showed that engagement in deliberate practice in soccer and futsal, especially during childhood and early adolescence, is related to a better quality of offensive decision-making skills, although showing small to medium effect sizes. We highlight that deliberate practice in futsal is associated only with offensive decision-making skills with the ball and near the ball. In turn, engaging in deliberate play in soccer, mainly in childhood and early adolescence, is related to quicker offensive and defensive decision-making skills, showing mostly medium effect sizes. To the best of our knowledge, it was the first study to measure the relationship of decision-making speed with developmental activities in soccer. It is concluded that deliberate practice in soccer and deliberate play in soccer are associated with different dimensions of decision-making skills.

RESUMEN

Os árbitros são agentes esportivos que contribuem para a promoção do fair play. Esse estudo tem por objetivo categorizar as classes de comportamentos que compõem a classe geral "manejar comportamentos antiesportivos e de fair play em atletas de Futsal". Empregou-se como fonte de informação o Código de Ética da Confederação Brasileira de Futsal e o Livro Nacional de Regras do Futsal. O procedimento foi composto pelas seguintes etapas: selecionar e registrar trechos das obras; identificar, destacar e registrar nos trechos selecionados as partes que contenham componentes das classes de comportamento; derivar e registrar componentes das classes de comportamentos; avaliar a linguagem dos componentes identificados; nomear as classes de comportamento; avaliar a linguagem; organizar e categorizar as classes de comportamento. Os resultados apontaram um total de 132 classes de comportamento categorizadas em: dever do árbitro e proibido ao árbitro. Descrever as classes de comportamentos aumenta a probabilidade de desenvolver intervenções mais eficientes e efetivas que capacitem os árbitros a manejarem comportamentos antiesportivos e de fair play nos jogos de futsal.

Referees are sports agents who contribute to the promotion of fair play. This study aims to categorize the classes of behaviors that make up the general class "Managing unsportsmanlike behavior and fair play in Futsal athletes". The Code of Ethics of the Brazilian Futsal Confederation and the National Futsal Norms Book were used as sources of information. The procedure consisted of the following steps: Select and record excerpts from the works; Identify, highlight and record in the selected sections the parts that contain components of the behavior classes; Derive and register components of behavior classes; Evaluate the language of the identified components; Naming the behavior classes; Assess language; Organize and Categorize Behavior Classes. The results showed a total of 132 behavior classes, which were categorized into: Referee's Duty and Referee's Prohibition. Describing behavior classes increases the likelihood of developing more efficient and effective interventions that allow referees to manage unsportsmanlike and fair play behavior in Futsal games.

RESUMEN

Introduction: Self-efficacy is considered a component of mental toughness, but there are few studies investigating the relationship of sport self-efficacy with mental toughness in performance athletes, especially in team sports. Objective: The objective was to examine the impact of sport self-efficacy mediated by mental toughness on the sport performance of Brazilian futsal athletes. Methods: The sample was composed of five adult male teams participating in the National Futsal League 2020, totaling 77 athletes. As instruments, we used: athlete identification sheet, Perceived Self-Efficacy Scale in Sports (PSES), Mental Toughness Index (MTI) questionnaire and the performance data from the National Futsal League 2020 (NFL). The data were analyzed using the Kolmogorov-Smirnov test, Mann-Whitney "U" test, Spearman's correlation, network analysis (LASSO), with the indicators of centrality: strength, proximity and degree of intermediation (p < 0.05). Results: The results showed that the investigated sample presented high levels of Perceived Self-Efficacy Scale in Sports (PSES) (Md = 4.66) and mental toughness (MT) (Md = 6.44). PSES presented a positive relationship with the number of wins, and negative relationships with the number of red cards and wrong passes (r = -0.08). MT indirectly influenced these variables through its connection with PSES (r = 0.30). The best ranked teams presented higher amounts of goals for, fouls, shots on goal, tackles, assists, and wins. The time of practice revealed an inverse relationship with the number of defeats, while age was positively related to the number of wrong passes (r = 0.09). The centrality indicators showed that the number of games stood out as the most central variable in the network, due to its degree of strength, proximity and intermediation. Moreover, the high degree of proximity and intermediation of the tackles made presented a connection with the number of assists (γ = 0.25; n = 77). Conclusion: We can conclude that sport self-efficacy and mental toughness are intervening factors in the sport performance of Brazilian futsal athletes.

RESUMEN

Os futebóis ainda não se constituem como uma prática integrante na dinâmica de vida de muitas mulheres no Brasil. Para buscar entender as relações e os motivos que as fazem não vivenciar estas determinadas modalidades, este artigo aborda as experiências de mulheres menos habilidosas com as aulas de futebol/futsal na Educação Física escolar. A partir do aporte teórico/metodológico da História Oral foram realizadas dezoito entrevistas com mulheres adultas que tiveram contato com a modalidade na escola, mas que hoje não possuem ligação com estes esportes. Através dos relatos, conclui-se que o desinteresse pelo futebol/futsal por parte das meninas menos habilidosas e a resistência dos meninos em jogar com as meninas, são resultado de tecnologias de gênero que constituem não só os alunos e alunas, mas também os professores/as que acabam sendo agentes que contribuem para as normas sociais de gênero estabelecidas.

Football is not yet an integral practice in the life dynamics of many women in Brazil. In order to seek to understand the relationships and the reasons that make them not experience these certain modalities, this article addresses the experiences of less skilled women with soccer/futsal classes in school Physical Education. From the theoretical/methodological contribution of Oral History, eighteen interviews were carried out with adult women who had contact with the modality at school, but who today have no connection with these sports. Through the reports, it is concluded that the lack of interest in soccer/futsal on the part of the less skilled girls and the resistance of the boys to play with the girls, are the result of gender technologies that constitute not only the students, but also the teachers. who end up being agents that contribute to established social gender norms.

El fútbol aún no es una práctica integral en la dinámica de vida de muchas mujeres en Brasil. Con el fin de buscar comprender las relaciones y las razones que hacen que no experimenten estas determinadas modalidades, este artículo aborda las experiencias de mujeres menos hábiles con las clases de fútbol/fútsal en la Educación Física. A partir del aporte teórico/metodológico de la Historia Oral, se realizaron dieciocho entrevistas a mujeres adultas que tuvieron contacto con la modalidad en la escuela, pero que hoy no tienen vinculación con estos deportes. A través de los informes se concluye que el desinterés por el fútbol/fútbol sala por parte de las niñas menos habilidosas y la resistencia de los niños a jugar con las niñas, son resultado de tecnologías de género que constituyen no solo a los estudiantes, sino también los docentes, quienes terminan siendo agentes que contribuyen a las normas sociales de género establecidas.

RESUMEN

Resumo O foco de investigação deste artigo está no contexto extracurricular de aulas de futsal em escolas particulares de Porto Alegre. O objetivo do estudo foi analisar a percepção dos professores da modalidade sobre a sua prática pedagógica em situação de participação de equipes escolares em competições. As atividades de cunho competitivo se mostram presentes nas escolas e impactam no aprendizado dos alunos e alunas. Os sete professores participantes da pesquisa foram entrevistados por meio de uma entrevista semiestruturada. As entrevistas, gravadas e transcritas, foram analisadas por meio da análise temática. Na prática pedagógica, a utilização de competições esportivas entre escolas parece ser central. As percepções dos professores entrevistados indicam as competições como algo que está presente e intimamente ligado à razão de existir da atividade; muitas vezes, acabam sendo utilizadas como um fim e não como um meio de aprendizado pedagogicamente estruturado.

RESUMEN

Oxidative stress is associated with playing soccer. The objective of the present report was to study the influence of different polyphenolic antioxidant-rich beverages in five-a-side/futsal players. The study was performed with a no supplemented control group (CG) and two supplemented groups with an almond-based beverage (AB) and the same beverage fortified with Lippia citriodora extract (AB + LE). At day 22, participants played a friendly futsal game. Blood extractions were performed at the beginning of intervention (day 1), before and after match (day 22) to determine oxidative stress markers and antioxidant enzyme activities in plasma, neutrophils and peripheral blood mononuclear cells (PBMCs). Malondialdehyde increased significantly in controls after the match in neutrophils, PBMCs and plasma compared to pre-match. Protein carbonyls also increased after the match in plasma in CG. In addition, malondialdehyde levels in neutrophils were significantly lower in the supplemented groups compared to controls. Post-match samples showed significant increases in neutrophil antioxidant activities in CG. Supplemented groups displayed variable results regarding neutrophil antioxidant activities, with superoxide dismutase activity significantly lower than in controls. Finally, post-match myeloperoxidase activity increased significantly in controls compared to pre-match and supplemented groups. In conclusion, polyphenolic antioxidant and anti-inflammatory supplements could be instrumental for optimal recovery after high intensity futsal games.

RESUMEN

Objective: No study has analyzed the effects of caffeine ingestion on performance during a multidirectional high-intensity intermittent exercise. Thus, we aimed to investigate the effects of caffeine ingestion during a novel repeated agility test in futsal athletes.Methods: Using a double-blind, counterbalanced, and repeated-measures design, ten athletes (mass 71.2 ± 8.7 kg, height 1.77 ± 0.05 m, body mass index 22.7 ± 1.9 km/m2, body fat percentage 10.2 ± 3.7%) performed a novel repeated-bout agility test 60 min after ingesting 6 mg · kg-1 of caffeine or cellulose (placebo).Results: Performance time decreased progressively throughout the trial in both conditions (P = 0.01; ηp2 = 0.66), with a significant interaction effect (P = 0.01; ηp2 = 0.35) showing a potential beneficial effect of caffeine at the beginning, followed by a decrease at the end of the test. Furthermore, magnitude of decrease in performance was more pronounced in caffeine (-9.0 ± 5.7%) compared with placebo (-4.7 ± 3.9%, P = 0.01; d = 0.88). Interestingly, magnitude-based inferences revealed a possible benefit (70%) of caffeine at the beginning, followed by likely (93%) to very likely (96%) impairments in performance during the last third of the test. Heart rate and rating of perceived effort increased in both conditions over the time (P < 0.05), with similar values between experimental conditions (P > 0.05).Conclusion: Caffeine seems to have a potential beneficial effect at the beginning, with an impaired performance during the final third of a new multidirectional high-intensity intermittent exercise in futsal athletes.

RESUMO Este estudo teve como objetivos analisar a trajetória de vida de árbitras de futsal da região Nordeste e refletir sobre como suas representações de "ser mulher árbitra" se articulam à sua identificação enquanto "mulher nordestina". Baseamo-nos nos campos da História Oral, História Cultural e nos Estudos de Gênero. Foram analisadas 13 entrevistas e documentos de acervos pessoais e institucionais. Nossas análises revelam que as interlocutoras se deparam com limitações às quais respondem recorrendo a variadas referências de gênero que, por sua vez, expõem as complexidades da categoria "mulher". Destacamos, aqui, o lugar de uma "identidade regional" ao qual elas frequentemente se referem ao tratarem das formas encontradas para questionarem e enfrentarem os preconceitos que atravessam suas trajetórias.

ABSTRACT This study aimed to analyze the life trajectory of referees from futsal in the northeastern region and reflect on how their representations of "being a referee woman" are linked to their identification as a "northeastern woman". We are based on Oral History, Cultural History and Gender Studies. Thirteen interviews and documents from personal and institutional collections were analyzed. Our analyzes reveal the interlocutors are faced with limitations and difficulties to which they respond by resorting to various references of gender and behavior that, in turn, expose the complexities of the "woman" category. We highlight the place of a "regional identity" that they often refer to when dealing with the ways found to question and face the prejudices that cross their trajectories.

Nuestros análisis revelan que los interlocutores enfrentan limitaciones a las que responden recurriendo a diversas referencias de género que, a su vez, exponen las complejidades de la categoría "mujer". Aquí, destacamos el lugar de una "identidad regional" a la que suelen referirse cuando se trata de las formas que encuentran para cuestionar y enfrentar los prejuicios.

RESUMEN

Abstract Aim: Prejudice against women's futsal players is reported in the literature. The perception of prejudice in university futsal may be lower due to the higher educational level of the players and a more open-minded context. This study aimed to describe the experience of young women university futsal players and to explore their perspective on gender prejudice in that sports practice. Methods: Ten women university futsal players (aged 18 to 30 years old) were interviewed. Data were produced and analyzed following a grounded theory approach. Results: The results showed that the athletes perceived they suffered gender prejudice for playing futsal, however, in the university context this was attenuated. The participants experienced diversified practice before specializing in futsal and felt that the support of male family members and friends was important to their engagement in futsal and soccer in childhood and adolescence. However, they also suffered from prejudice against their futsal practice coming from family and friends, struggling with the constant association between futsal practice and hegemonic masculinity. Conclusion: The participants of this study perceived less prejudice in university women's futsal in comparison to other sports contexts. Thus, the university context may have the potential to boost the practice of futsal among women.

RESUMEN

Abstract Introduction: The relative age effect is prevalent in different elite team sports. However, little is known about this phenomenon in high-level adult male futsal players. Aim: The present study aimed to investigate the prevalence of relative age effect in Brazilian male elite futsal players, and its relationship with playing position and goals scored on Brazil National Futsal Leagues (BNFL) from 2016 to 2020. Methods: The distribution of birth dates, playing positions, and goals scored by male participants of the Brazil National Futsal Leagues were analyzed. Chi-squared tests were used to analyze the birth dates distribution based on quarters and semesters of the year, according to playing position (defender, winger, pivot, and goalkeeper) and scoring performance (high and low). Results: The overall analysis indicated that the relative age effect is prevalent on the pool of athletes analyzed. However, this effect was position-dependent, since relatively older athletes were overrepresented only in wingers and defenders playing positions. On the other hand, scoring performance was not associated with the relative age effect, since this effect was found in both performance levels. Conclusion: Relative age effects are prevalent in Brazilian male elite futsal athletes, especially for defenders and wingers. Considering the high level of competitiveness for spots in elite futsal teams, coaches and sports administrators must be educated about the prevalence of the relative age effect in this sporting context. This is necessary in order to reduce the inequalities generated by age categories based on arbitrary cut-off dates, which may reduce potential talent loss.

RESUMEN

A relação entre a ansiedade pré-competitiva e desempenho esportivo ainda se encontra pouco explorada pela literatura científica, principalmente nas modalidades coletivas. Assim o objetivo do estudo foi analisar as respostas de ansiedade pré-competitiva e desempenho percebido em relação ao local de jogo em atletas de futsal. Foram avaliados 14 atletas do sexo masculino (20,64±3,93 anos de idade) pertencentes a uma equipe de futsal, em um jogo dentro e um jogo fora de casa. A ansiedade pré-competitiva foi avaliada pelo questionário Revised Competition State Anxiety Inventory-2(CSAI-2R) antes de cada jogo e o desempenho percebido pela escala Likert (0 a 4) após cada jogo. Utilizou-se o tamanho do efeito (TE) para as diferenças entre os jogos paras as variáveis de ansiedade e o teste de Friedman para o desempenho percebido, considerando P < 0,05. Como principais resultados foram observados um TE moderado e incerto para a ansiedade somática (TE=0,75; LC= -0,19; 1,62) e cognitiva (TE=0,70; LC=-0,23; 1,52), com maiores valores no jogo em casa. Para a autoconfiança um efeito pequeno e incerto (TE=0,20; LC=-0,69;1,70). A percepção de desempenho não diferiu entre os jogos (P=0,564). Conclui-se que o local de jogo afeta moderadamente nas respostas pré-competitivas de ansiedade somática e cognitiva, assim jogar em casa pode ser percebido pelos atletas como uma maior ameaça, porém de maneira incerta. Essa variação nas respostas de ansiedade, entretanto parecem não impactar negativamente nas respostas de percepção de desempenho desses atletas.(AU)

The relationship between precompetitive anxiety and sports performance remains poorly explored in the scientific literature, especially in sports-team. In this study, we aim to analyze the relationship between precompetitive anxiety and perceived performance in futsal athletes, considering the game location. Fourteen male athletes (20.64 ± 3.93 years old) belonging to a futsal team in a home and away game was evaluated. Precompetitive anxiety was assessed by the Revised Competition State Anxiety Inventory-2(CSAI-2R) questionnaire before each game and the performance perceived on the Likert scale (0 to 4) after each game. Effect size (ES) was used to analyze the difference between the games for the anxiety and the Friedman test to analyze the perceived performance, considering P < 0.05. Main results included a moderate and unclear effect of somatic (ES= 0.75, CL = -0.19; 1.62)and cognitive anxiety (ES= 0, 70; CL = -0.23; 1.52) with higher values in the game played at home. Small and unclear effect was found for self-confidence (ES= 0.20; CL = -0.69; 1.70). The perception of performance did not differ between games (P = 0.564). We can conclude that the game location moderately affects the precompetitive responses of somatic and cognitive anxiety, so playing at home can be perceived by the athletes as a major treat, but unclearly. This variation in anxiety-responses does not seem to impact directly on performance perception.(AU)

RESUMEN

Este estudo buscou identificar a presença dos três referenciais do ensino esportivo da Pedagogia do Esporte nas disciplinas de futsal de cursos de Educação Física, discutindo possíveis direcionamentos na formação de professores e treinadores da modalidade. Consideramos apenas cursos presenciais, de universidades públicas, ativos no segundo semestre de 2019. Por meio de uma análise documental, investigamos ementas, programas e objetivos das disciplinas. Ao realizar uma Análise Temática sobre os 110 documentos encontrados, percebemos que estes priorizam os conteúdos voltados ao Referencial Técnico-tático e que existe grande defasagem em relação ao Referencial Socioeducativo. Assim, uma vez evidenciado o desequilíbrio exposto nesta pesquisa, estes resultados podem contribuir em revisões de ementas e currículos, na expectativa de que a importância atribuída aos conteúdos técnico-táticos nas disciplinas de futsal seja estendida aos elementos históricos, culturais, educativos e sociais.

The study aims to identify the presence of the three references of sports learning from Sport Pedagogy in Futsal subjects from Physical Education Degree, discussing possible directions on the development of professors and coaches of this sport. We only considered the presential courses, of public universities, active on the second semester of 2019. Through a documental analysis, we searched syllabus, curriculums, and discipline goals. Performing a Thematic Analysis about the all 110 files founded, we realized that they prioritize the technical-tactical elements and present a huge gap in relation of socio-educational reference. Thus, once the unbalance exposed in this research is evidenced, the results can contribute to syllabus and curriculum revisions, in the expectation that the importance attributed to the technical-tactical elements will be extended to historical, culture, educational and socials elements.
