A pesquisa sobre o futebol no Brasil: análise dos grupos de pesquisa e da produção científica recente / La investigación sobre el fútbol en Brasil: análisis de los grupos de investigación y de la producción científica reciente / Football research in Brazil: analysis of scientific research groups and recent scientific production

Este estudo teve como objetivo identificar, mapear e analisar os grupos de pesquisa (GP) sobre futebol no Brasil, a quantidade e a qualidade da produção científica dos pesquisadores líderes. Trata-se de um estudo sistemático, descritivo, realizado na base de dados do Diretório de Grupos de Pesquisa no Brasil do Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq). Analisou-se a produção científica recente (2016 e 2022) disponível no currículo Lattes dos líderes. Identificaram-se 46 GP, a maioria deles localizados nas regiões Sudeste e Sul do Brasil (n=22/47,8%). O primeiro GP não específico surgiu em 1984 e em 2006 foi cadastrado o primeiro GP específico. Nos últimos anos, foram 409 publicações sobre futebol. Conclui-se que houve um aumento de GP recentemente, com tendência de estabilidade nas publicações, melhora na qualidade dos artigos em periódicos com melhor estratificação Qualis e fator de impacto, indicando avanços nas pesquisas sobre futebol no Brasil.

This study aimed to identify, map, and analyze the research groups (RG) on football in Brazil, through the quantity and quality of the scientific production of research leaders. This is a systematic and descriptive study carried out in the database of the Directory of Research Groups of Brazil of the National Council for Scientific and Technological Development (CNPq). We analyzed the scientific production (2016 and 2022) of the Lattes of the leader's curriculum. In total, 46 groups were identified, the majority located in the Southeast and South regions of Brazil (n=22/47.8%). The first non-specific RG appeared in 1984 and the first specific RG was registered in 2006. In recent years, these RGs have been responsible for 409 publications about football. It is concluded that there has recently been an increase in RGs, with a trend towards stability in publications, indicating advances in research on football in Brazil. (AU)

Effect of practice exergames on the mood states and self-esteem of elementary school boys and girls during physical education classes: A cluster-randomized controlled natural experiment.

Reduced physical exercise can impact children's mental health. Use of active electronic games can help promote psychological health. Physical education (PE class) uses different resources, methods, and contents to promote student health. We investigated the effect of exergames on the mood and self-esteem of children and compare it that of with traditional PE classes. From a sample of 213 children (7-11 years old), 140 from 10 classes of the fourth and fifth grades of elementary school (59 boys, 81 girls; mean age 9.41±0.48 years), allocated to an experimental group (EG; n = 68; five clusters) and a PE group (PE; n = 72; five clusters), participated in this experimental controlled study. The EG practiced exergames during three 40-minute classes, and the PE group held three routine curricular PE classes. Brunel's Mood Scale and Rosenberg's Self-Esteem Scale were applied. Repeated measures ANOVA identified differences between sexes and groups. The main results of the EG demonstrated reduced tension in girls (p <0.05; ES: 0.62; 95% CI: 0.17-1.05). Regarding sex comparisons, anger was lower in girls (F: 4.57; p <0.05; ES: 0.61; 95% CI: 0.11-1.11) in the EG. Vigor was higher in girls in the EG than in those in the PE group (F: 5.46; p <0.05; ES: 0.56; 95% CI: 0.12-1.01). The main results of the PE group indicated increased self-esteem in boys (p <0.05; ES: 0.58; 95% CI: 0.08-1.07) and reduction of girls' mental confusion (p <0.05; ES 0.58; 95% CI 0.15-1.06). Thus, exergames impact boys' and girls' self-esteem and mood, as well as traditional physical education classes. Further study on exergames in schools is essential, with long-term effects on physical and mental health. Exergames bring interesting, varied content, technology, and innovation that can increase the attractiveness of physical education.

Acute Effect of Exergames on Children's Mood States During Physical Education Classes.

Objective: We aimed to confirm whether the practice of exergames produces an effect on children's mood states during school physical education (PE) classes. Materials and Methods: The children were allocated to experimental group (EG) and control group (CG). The EG performed exergames during PE classes, and the CG attended regular school PE classes. The Brunel Mood Scale, which evaluates six mood dimensions (tension, mental confusion, anger, vigor, depression, and fatigue), was used to assess the children's moods before (pre) and immediately after the third lesson (acute effect). Results: The practice of exergames during PE classes produced an acute effect on children's moods. The results indicated that playing exergames helped to increase vigor (P < 0.01; effect size [ES]: 0.50; confidence interval [CI]: 0.16-0.84) and fatigue (P < 0.01; ES: 0.50; CI: 0.16-0.84). Conclusion: Three exergame sessions produced an acute effect and improved children's moods during school PE classes. More research is needed to evaluate the long-term effect of exergames on children and adolescents.
