ABSTRACT

Introducción: lograr la interacción entre los equipos de salud y la educación, es fundamental para generar futuras generaciones con conocimientos y destrezas que les permitan cuidar su salud, la de sus familias y comunidades. Durante la edad escolar se desarrollan gran parte de las preferencias, costumbres y estilos personales. Objetivo: conocer los hábitos, conductas y prácticas de las niñas, niños y adolescentes de quinto y sexto año de tres instituciones educativas públicas y tres privadas de Montevideo para realizar un diagnóstico de situación que permita planificar una intervención posterior. Material y método: estudio descriptivo, observacional y transversal entre octubre y diciembre 2017. Se aplicó una encuesta anónima a escolares de quinto y sexto año de tres instituciones públicas y tres privadas de los barrios Paso de la Arena, Prado y Colón. Se solicitó consentimiento informado y autorización al comité de investigación institucional. Se utilizaron frecuencias absolutas y porcentajes. Resultados: participaron 331 escolares, 73,1% del sector público y el 26,9% del privado. En la merienda escolar, 46% consume merienda casera y 75% comprada. El 53% no consume alimentos UP en el recreo. En el hogar un 50% come frutas y un 35% come verduras todos los días, un 64,3% consume carne UP hasta 3 veces por semana. Si bien un 48,3% refiere correr todos los días, casi cuatro de cada diez nunca bailan, patinan o andan en bicicleta y dos de cada diez nunca practican deportes. El 65% destina más de 2 horas a las pantallas, 2 de cada 10 duermen menos de 6 horas y más del 50% usan el celular o miran televisión antes de dormir. Se encontraron diferencias entre el sector público y privado en la merienda casera, consumo de UP, carne y agua. Conclusiones: se realizó un diagnóstico de los hábitos, conductas y prácticas de los escolares de esas 3 zonas que permitió elegir los temas prioritarios de salud para trabajar con esas escuelas. La situación es inquietante y debe trabajarse con celeridad a nivel interinstitucional generando cambios en los hábitos de vida de los escolares, sus familias y la comunidad. Se determinó un punto de partida para poder evaluar y medir el impacto de las acciones.


Introduction: promoting interaction between health and educational teams is essential to build the necessary skills and knowledge in future generations that would enable them to take care of their health, their families' and their communities'. Most preferences, habits and personal styles are developed at school age. Objective: to get to know the habits, behaviors and practices of children and adolescents of fifth and sixth grade attending three public and three private educational institutions in Montevideo and make a diagnosis of the situation to able to plan a subsequent intervention. Material and Methods: descriptive, observational and crosssectional study between October and December 2017. An anonymous survey was applied to fifth and sixth grade students from three public and three private institutions in the Paso de la Arena, Prado and Colón neighborhoods. Informed consent and authorization were obtained from the institutional research committee. Absolute frequencies and percentages were used. Results: 331 school children participated, 73.1% from the public sector and 26.9% from the private sector. Regarding school snacks, 46% of them consume homemade snacks and 75% consume processed snacks. 53% do not consume food during recess. At home 50% eat fruits and 35% eat vegetables every day, 64.3% consume UP meat up to 3 times a week. While 48.3% report running every day, almost four out of ten have never danced, skated or ridden a bike and two out of ten have never played sports. 65% spend more than 2 hours watching screens, 2 out of 10 sleep less than 6 hours and more than 50% use the cell phone or watch television before bed. We found significant differences between the public and private sectors regarding homemade snacking, meat and water consumption. Conclusions: we carried out a diagnosis of the habits, behaviors and practices of schoolchildren in these 3 areas, which enabled us to choose priority health topics to work with these schools. The situation is disturbing and it must be addressed quickly at interinstitutional level in order to generate changes in the schoolchildren habits, their families and their communities. We have set up a starting point in order be able to evaluate and measure the impact of actions taken.


Introdução: alcançar a interação entre as equipes de saúde e de educação é essencial para gerar conhecimentos e habilidades nas gerações futuras que lhes permitam cuidar de sua saúde, a de sua família e a de suas comunidades. A maior parte das preferências, costumes e estilos pessoais são desenvolvidos durante a idade escolar. Objetivo: conhecer os hábitos, comportamentos e práticas de crianças e adolescentes do quinto e sexto ano de ensino fundamental de três instituições de ensino público e três de ensino privado de Montevidéu para fazer um diagnóstico da situação que permita planejar uma intervenção posterior. Material e Métodos: estudo descritivo, observacional e transversal entre outubro e dezembro de 2017. Uma pesquisa anónima foi aplicada a alunos do quinto e sexto ano do ensino fundamental de três instituições públicas e três privadas dos bairros Paso de la Arena, Prado e Colón. Consentimento informado e autorização foram solicitados ao comitê de pesquisa da instituição. Foram utilizadas frequências absolutas e porcentagens. Resultados: participaram 331 escolares, sendo 73,1% do setor público e 26,9% do setor privado. Na merenda escolar, 46% consomem lanche caseiro e 75% compram. 53% não consomem alimentos UP no recreio. Em casa 50% comem frutas e 35% comem vegetais todos os dias, 64,3% consomem carne UP até 3 vezes por semana. Enquanto 48,3% relatam correr todos os dias, quase quatro em cada dez nunca dançam, patinam ou andam de bicicleta e dois em cada dez nunca praticam esportes. 65% passam mais de 2 horas assistindo a telas de computador ou telefones, 2 em cada 10 dormem menos de 6 horas e mais de 50% usam o celular ou assistem à televisão antes de dormir. Foram encontradas diferenças entre os setores público e privado no consumo de lanches caseiros, UP, carne e água. Conclusões: um diagnóstico dos hábitos, comportamentos e práticas dos escolares das 3 zonas que permitiram escolher os temas prioritários de saúde para trabalhar com estas escolas. A situação é preocupante e deve ser trabalhada rapidamente no nível interinstitucional, com o fim de gerar mudanças nos hábitos de vida dos escolares, de suas famílias e da comunidade. Determinouse um ponto de partida para poder avaliar e mensurar o impacto das ações realizadas.

ABSTRACT

Resumo Petroni de Senzi Barreira, C., da Silva Musa, V. e Pereira Morato, M. (2021). Eficácia dos sistemas defensivos em superioridade e igualdade numérica no handebol: panorama de uma competição europeia. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 19(2), 1-13. As ações e escolhas realizadas durante a fase defensiva no handebol podem ser determinantes para os resultados das partidas. Análises abordando essa fase do jogo vêm sendo realizadas para identificar aspectos determinantes e que possam auxiliar no planejamento e treinamentos das equipes. Este estudo teve como objetivo analisar a influência das relações numéricas nos sistemas defensivos fechados e abertos no handebol de alto nível. Para isso foram analisados 12 jogos do campeonato europeu de handebol de clubes, cujo instrumento de análise permitiu identificar a relação numérica do jogo (superioridade ou igualdade numérica defensiva) e quantificar os resultados (GO: gol; NG: não-gol; PP: perda de posse da bola) e os locais em que se encerraram as ações ofensivas. Foi utilizado o teste qui-quadrado para análise dos dados. Os resultados apontaram semelhanças para a conclusão do ataque mediante situações de igualdade com a utilização dos sistemas fechados (GO = 47.3%; NG = 33.6%; PP = 19.1%) e dos sistemas abertos (GO = 46.0%; NG = 34.3%; PP = 19.7%). Para essa situação, demonstrou-se que a utilização dos sistemas fechados provoca o encerramento da posse mais distante do gol (9m- = 56.9%; 9m+ = 43.1%), quando comparado à utilização dos sistemas abertos (9m- = 64.5%; 9m+ = 35.5%). Em situações de superioridade numérica defensiva a utilização dos sistemas abertos (GO = 28.6%; NG = 53.6%; PP = 17.9%), quando comparados aos sistemas fechados (GO = 49.3%; NG = 29.6%; PP = 21.1%), apresentou maior eficácia nos resultados das ações. Além disso, as sequências se encerraram mais distantes do gol quando foram utilizados sistemas abertos (9m- = 42.9%; 9m+ = 57.1%) em comparação aos sistemas fechados (9m- = 68.3%; 9m+ = 31.7%). Conclui-se que a escolha do sistema defensivo deve ser pautada no modelo de jogo da equipe e nas relações recorrentes do jogo, nos momentos de igualdade numérica (mais frequentes). Porém, em momentos de vantagem numérica defensiva limitar o espaço e o tempo para que os atacantes tomem decisões mostra-se como uma estratégia eficaz.


Abstract Petroni de Senzi Barreira, C., da Silva Musa, V. & Pereira Morato, M. (2021). Efficiency of handball defensive systems in numerical equality and superiority: panorama of a european competition. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 19(2), 1-13. Actions taken during the defensive phase in handball can determine match results; therefore, analyzing this phase helps identify key aspects that can assist in team training and planning. The aim of this paper was to analyze the influence of numerical relations on closed and open defense systems in top level handball matches. Twelve matches of the European handball club championship were analyzed, which allowed us to identify the numerical relationship of the game (defensive superiority or equality) and quantify results (GO: goal; NG: non-goal; PP: loss of ball possession) and the sections of the court where offensive actions ended up. A chi-squared test was used for data analysis. Results showed similarities in terms of the attack's conclusion in numerical equality situations, when defense used closed systems (GO = 47.3%; NG = 33.6%; PP = 19.1%) and open systems (GO = 46.0%; NG = 34.3%; PP = 19.7%). For this situation, using closed systems results in losing ball possession further from the goal (9m- = 56.9%; 9m+ = 43.1%), when compared to open systems (9m- = 64.5%; 9m+ = 35.5%). In defensive numerical superiority, using open systems (GO = 28.6%; NG = 53.6%; PP = 17.9%), compared to closed systems (GO = 49.3%; NG = 29.6%; PP = 21.1%) gives more efficient results. In addition, sequences end further from the goal when open systems were used (9m- = 42.9%; 9m+ = 57.1%), compared to closed systems (9m- = 68.3%; 9m+ = 31.7%). It was concluded that the selection of the defensive system should be based on the team's game model and game relationships, especially in situations of numerical equality (more frequent). However, when in defensive numerical advantage, limiting the space and time for attackers to make decisions seems to be an effective strategy.


Resumen Petroni de Senzi Barreira, C., da Silva Musa, V. y Pereira Morato, M. (2021). Eficacia de los sistemas defensivos en superioridad e igualdad numérica en balonmano: panorama de una competición europea. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 19(2), 1-13. Las acciones realizadas durante la fase defensiva en balonmano pueden ser determinantes para los resultados de los partidos, y los análisis en esta fase permiten identificar aspectos clave que pueden ayudar en la planificación y entrenamiento de los equipos. El objetivo de este trabajo fue analizar la influencia de las relaciones numéricas en sistemas defensivos cerrados y abiertos en partidos de balonmano de alto nivel. Se analizaron doce partidos del Campeonato de Europa de clubes de Balonmano, cuyo instrumento de análisis permitió identificar la relación numérica del juego (superioridad defensiva o igualdad) y cuantificar los resultados (GO: gol; NG: sin gol; PP: perdida del balón) y regiones de la cancha en las que terminaron las acciones ofensivas. Se utilizó la chi-cuadrado para el análisis de datos. Los resultados mostraron similitudes para la realización del ataque a través de situaciones de igualdad con el uso de sistemas cerrados (GO = 47.3%; NG = 33.6%; PP = 19.1%) y sistemas abiertos (GO = 46.0%; NG = 34.3%; PP = 19.7%). Para esta situación, se demostró que el uso de sistemas cerrados provoca la pérdida del balón más lejos de la portería (9m- = 56.9%; 9m + = 43.1%), cuando se compara con el uso de sistemas abiertos (9m- = 64.5%; 9m + = 35.5%). En superioridad numérica defensiva, el uso de sistemas abiertos (GO = 28.6%; NG = 53.6%; PP = 17.9%), en comparación con sistemas cerrados (GO = 49.3%; NG = 29.6%; PP = 21.1 %), mostró mayor efectividad en los resultados de las acciones. Además, las secuencias terminaron más lejos del objetivo cuando se utilizaron sistemas abiertos (9m- = 42.9%; 9m+ = 57.1%), en comparación con sistemas cerrados (9m- = 68.3%; 9m+ = 31.7%). Se concluyó que la elección del sistema defensivo debe basarse en el modelo de juego del equipo y en las relaciones recurrentes del juego, especialmente en situaciones de igualdad numérica (más frecuentes). Sin embargo, cuando se tiene una ventaja numérica defensiva, limitar el espacio y el tiempo para que los atacantes tomen decisiones parece ser una estrategia eficaz.

ABSTRACT

ABSTRACT Among the possible languages of contemporary social media, the ubiquity of images has heightened the sense of on-line communication, and has been used to shape both personal identities and institutions'recognition. Such visual content is not only an artefact of social media isolated and individual, but surrounds itself with debates and discussions that involve political, legal, economic, technological and sociocultural ideologies. Based on Instagram Image and use of Cohen's kappa for reliability and validity of data, this study analyzed 2679 photos that were posted on Instagram of the Brazilian Gymnastics Federation (CBG). As a result, we noticed the prevalence of artistic gymnastics (54,1%), followed by rhythmic gymnastics (31%), both within elite level focus (97%) specially on international events (59,6%) with greater appearance of athletes (66%). These findings reflect the need to review the use of social media in order to contemplate the broad actions of CBG, such as the diffusion of all gymnastics disciplines, as well as their different events at various levels of practice, giving visibility to all sports persons.


RESUMO Dentre as possíveis linguagens das mídias sociais contemporânea, a onipresença das imagens elevou o sentido da comunicação on-line, e tem sido utilizada para moldar tanto identidades pessoais como de diversas instituições. Tais conteúdos visuais não são apenas artefatos de mídias sociais isolados e individuais, mas se cercam de debates e discussões que envolvem ideologias políticas, legais, dimensões econômicas, tecnológicas e socioculturais. Baseados na Análise de Imagem do Instagram e utilização do Cohen's kappa para confiabilidade e validade dos dados, esta pesquisa analisou 2679 fotos postadas no Instagram da Confederação Brasileira de Ginástica (CBG). Como resultados, notamos a prevalência de postagens sobre ginástica artística (54,1%), seguida pela ginástica rítmica (31%), com foco na prática do alto rendimento (97%), divulgação de campeonatos internacionais (59,6%) e, cujo atleta (66%) foi protagonista. Esses achados apontam a necessidade de revisar o uso das mídias sociais no intuito de contemplar as amplas ações da instituição, como a difusão de todas as modalidades ginásticas e seus diferentes eventos; nos diversos níveis de prática, sejam de alto rendimento ou de formação, assim como dando visibilidade a todos os atores do esporte.

ABSTRACT

Resumo: Introdução: Diante da pandemia da Covid-19, os(as) estudantes de Medicina tornaram-se ainda mais fragilizados(as) e vulnerabilizados(as) pelo contexto de isolamento social, uma vez que tiveram suas rotinas alteradas. Assim, a Associação Atlética Acadêmica Marcel Resende Davi (AAAMRD), visando cumprir com a sua responsabilidade social de promoção da saúde, buscou incentivar a prática desportiva ao valorizar esse hábito em prol do bem-estar físico e mental dos(as) estudantes. Desse modo, este artigo objetiva relatar a experiência da atlética com a realização de um desafio esportivo virtual entre suas equipes. Relato de experiência: O desafio foi elaborado e executado remotamente para 112 atletas de 14 equipes esportivas. Nos grupos de WhatsApp®, particulares de cada time, os(as) atletas deveriam enviar mídias dos exercícios físicos realizados e contabilizá-los em uma lista. Ressalta-se que foram disponibilizados treinos nas redes sociais da atlética, em parceria com profissional capacitado, como forma de proporcionar treinos seguros. Ao final das 11 semanas de desafio, as três melhores equipes foram premiadas. Aplicou-se também um formulário de feedback para verificar a efetividade da ação. Discussão: A tecnologia, importante aliada na organização do desafio, permitiu que a promoção da saúde ocorresse remotamente, respeitando o distanciamento social. Ao estimular a constância de treinos, a atlética contribuiu para a manutenção de parte da rotina dos(as) graduandos(as), prejudicada pelo contexto pandêmico. Além disso, o espírito de coletividade e a interação entre os(as) atletas dentro dos grupos contribuíram para que esse distanciamento não fosse total, formando uma rede de apoio ao compartilharem também seus medos, inseguranças e saudades. Conclusão: Os resultados alcançados com o desafio e os feedbacks positivos confirmaram a efetividade da promoção da saúde proposta pela AAAMRD. Ademais, em conformidade com as Diretrizes Curriculares Nacionais e apesar do momento adverso, a instituição mostrou-se presente na formação pessoal e profissional dos(as) estudantes.


Abstract: Introduction: In the face of the COVID-19 pandemic, medical students have become even more fragile and vulnerable due to social isolation, since their routines have been altered. Thus, the Marcel Resende Davi Academic Athletic Association (AAAMRD), fulfilling its social responsibility to promote health, sought to encourage the practice of sports, highlighting the benefit of this habit for students' physical and mental well-being. This article aims to report the institution's experience of organising a virtual sports challenge among its teams. Experience report: The challenge was designed and executed remotely for 112 athletes from 14 sports teams. In Whatsapp® groups, private to each team, athletes were asked to send media of the physical exercises they performed and count them in a list. It is noteworthy that training was made available on the AAAMRD social networks, in partnership with a trained professional, as a way to provide safe training. At the end of the 11-week challenge, the top three teams were awarded. A feedback form was also applied to verify the effectiveness of the action. Discussion: Technology, an important ally in organizing the challenge, allowed health promotion to take place remotely, respecting social distance. By encouraging constant training, the AAAMRD helped maintain part of the undergraduate students' routine, hampered by the pandemic. Moreover, the collective spirit and interaction between athletes, within their respective groups, corroborated to reduce the distance between them, forming a support network in which they could also share their fears and insecurities. Conclusion: The results achieved through the challenge and the positive feedback confirmed the effectiveness of the health promotion proposed by AAAMRD. Furthermore, in accordance with the Brazilian National Guidelines for Undergraduate Medical Education and, despite the adverse moment, the institution remained present in the students' personal and professional development.

ABSTRACT

BACKGROUND@#Among former Olympic-level athletes, engagement in different sport disciplines has been associated with mortality risk in subsequent years. However, limited evidence is available on whether engagement in different sport disciplines at a young age is associated with locomotive syndrome (LS) risk later in life. This study examined the relationship between engagement in different sport disciplines during university years and LS risk in older age among former university athletes.@*METHODS@#Participants were 274 middle-aged and 294 older men alumni who graduated from a school of physical education in Japan. LS risk was defined as answering "yes" to any of the Loco-check questions. Data on university sports club membership were collected using questionnaires. University clubs were classified into three groups of cardiovascular intensity (low, moderate, high), following the classification system of sport disciplines by the American College of Cardiology. This classification considers the static and dynamic components of an activity, which correspond to the estimated percent of maximal voluntary contraction reached and maximal oxygen uptake achieved, respectively. University clubs were grouped based on the risk of bodily collision (no, yes) and extent of physical contact (low, moderate, high). Relationships between engagement in different sport disciplines and LS risk were analyzed using Cox proportional hazards models, and adjusted for age, height, weight, joint disease, habitual exercise, and smoking and drinking status.@*RESULTS@#Adjusted hazard ratios and 95% confidence intervals associated with the low, moderate, and high cardiovascular intensity sports were 1.00 (reference), 0.48 (0.22-1.06, P = 0.070), and 0.44 (0.20-0.97, P = 0.042) in older men, respectively; however, there was no significant association between these parameters among middle-aged men. Engagement in sports associated with physical contact and collision did not affect LS risk in either group.@*CONCLUSIONS@#Engagement in sports associated with high cardiovascular intensity during university years may reduce the risk of LS in later life. Encouraging young people to participate in such activities might help reduce LS prevalence among older populations.

ABSTRACT

RESUMO Objetivamos explorar a interpretação de imagens de lutadoras de artes marciais mistas (MMA) postadas no Instagram. Nos apoiamos nos debates pós-estruturalistas, especialmente aqueles que tratam do corpo e gênero. Para a coleta de dados, utilizamos dois grupos focais com estudantes universitários(as), um constituído por mulheres e outro por homens. A partir de uma análise de conteúdo, quatro categorias discursivas emergiram das interações grupais. Evidenciamos a permanência de estereótipos usuais sobre a participação da mulher no esporte, com o olhar dos homens tendencioso para a objetivação do corpo das lutadoras. As mulheres mostraram-se mais sensíveis às feminilidades plurais. A tendência de comparação entre atletas masculinos e femininos foi observada em ambos os grupos. Constata-se que a autoapresentação das lutadoras negocia, em certa medida, com a inconformidade de uma feminilidade hegemônica no espaço do Ultimate Fighting Championship (UFC).


ABSTRACT We aim to explore the interpretation of images of mixed martial arts fighters (MMA) posted on Instagram. We rely on poststructuralist debates, especially those dealing with body and gender. For data collection, we used two focus groups with college students, one made up of women and the other of men. From a content analysis, four discursive categories emerged from group interactions. We highlighted the permanence of the usual stereotypes about women's participation in sport, looking at how men have biases due to the objectification of the fighters' bodies. Women were more sensitive to plural femininities. The trend of comparison between male and female athletes was observed in both groups. The debate about the plural femininity was accepted, to some extent by the groups but other opinions also existed showing some resistance to the self-representation of the fighters regarding the non-conformity of hegemonic femininity in the UFC space.

ABSTRACT

RESUMO O objetivo deste estudo foi comparar a carga de treinamento em três tipos de treinamentos de uma equipe de voleibol profissional.. Participaram do estudo 28 jogadores (26,6 ± 4,7 anos; 91,5 ± 8,5 Kg; 194,1 ± 6,0 cm). Foi realizada uma análise descritiva de 29 sessões de treino técnico, 84 tecnico-tático e 75 de musculação e isoladamente das variáveis que compõem a carga de treinamento, PSE e o tempo de duração da sessão, posteriormente sendo reunidos em média e desvio padrão de acordo com tipo de treino. Para análise dos dados foi adotado o teste de Shapiro-Wilk e em seguida aplicou-se o teste Anova Two-Way com o Post Hoc de Tamhane e também foi utilizado o tamanho do efeito para análise das comparações. Os resultados demonstraram respostas significativas e grande tamanho de efeitos quando comparados técnico e técnico-tático com a musculação na carga interna de treinamento TxM (TE=1,2: grande; p= 0,002); TTxM (TE=1,3: grande; p= 0,001) e no tempo de duração da sessão TxM (TE=1,7: grande; p= 0,001); TTxM (TE=2,0: grande; p= 0,001), já a PSE da sessão apresentou apenas uma diferença sigifcativa TTxM (TE= 0,8: moderado; p= 0,001). Os estímulos de treinamentos específicos de quadra como técnico e técnico-tático promoveram maior carga interna nos atletas do que o treino de força, através principalmente pela influencia da variável tempo de duração da sessão que refletiu a carga externa.


ABSTRACT The aim of this study was to compare the training load in three types of training of a professional volleyball team. Participants were 28 players (26.6 ± 4.7 years, 91.5 ± 8.5 kg; 194.1 ± 6.0 cm). A descriptive analysis of 29 technical training sessions, 84 technical-tactical training sessions and 75 training sessions, and of the variables that compose the training load, PSE and the duration of the session were performed, and were then collected on average and standard deviation according to with type of training. To analyze the data, the Shapiro-Wilk test was adopted, and then the Anova Two-Way test was applied with Tamhane's Post Hoc and the effect size was also used for analysis of the comparisons. The results demonstrated significant responses and a large effect size when compared to technical and tactical-to- strength training (T = 1.2: large; p = 0.002); TTxM (TE = 1.3: large, p = 0.001) and the duration of the session / external load in the TxM training (TE = 1.7: large; p = 0.001); TTxM (TE = 2.0: large, p = 0.001), whereas the PSE of the session showed only a sigifcant difference TTxM (TE = 0.8: moderate; p = 0.001). The stimuli of specific training of court as technician and technician-tactician promoted greater internal load in the athletes than the strength training, mainly through the influence of the variable time of the session that reflected to external load.

ABSTRACT

ABSTRACT The aim of the present study was to identify the most used techniques by medalists and defeated athletes during the Brazilian Shotokan Karate Championship of 2017. Eleven fights involving thirteen athletes (28.5±3.7yrs.) who competed in the category "up to 65 Kg 1st KYU" were investigated. Analysis were conducted by six specialists through the observation and register technique using the tactical and technical spreadsheet Scout Karate. The Anova test was used to compare actions and techniques mostly used. The Chi-square test for independent samples was used to verify the existence of significant differences among the techniques used by the winning and defeated athletes (p<0.05). Results show that the most frequent attack during fights was the "Mawashi geri", 26.3±1.5 times, followed by "Gyaku zuki" with 19.5±2.0 times (p<0.01). The most visualized tactical action during combats was the attack with 47.5±5.5 times (p<0.01). "Mawashi geri" was the mostly used attack (p=0.01) performed by winners (71.4%) when compared with the defeated athletes (28.6%). The results indicate that the "Mawashi geri" attack was the most assertive decision used in the category "up to 65 Kg 1st KYU".


RESUMO O objetivo do presente estudo foi identificar as técnicas mais utilizadas por medalhistas e atletas derrotados durante o Campeonato Brasileiro de Karatê Shotokan de 2017. Onze lutas envolvendo treze atletas com 28.5 ± 3.7 anos que disputaram a categoria 1º. KYU até 65 kg foram investigados. A análise foi realizada por seis especialistas por meio da observação e registro de técnicas utilizando planilha tática e técnica de Scout de Karatê. O teste Anova foi utilizado para comparar as ações e técnicas mais utilizadas. O teste do qui-quadrado para amostras independentes foi utilizado para verificar a existência de diferenças significativas entre as técnicas utilizadas pelos atletas vencedores e derrotados (p<0.05). Os resultados mostram que o ataque mais frequente durante as lutas foi "Mawashi geri", 26.3 ± 1.5 vezes, seguido de "Gyaku zuki" com 19.5 ± 2.0 vezes (p<0.01). A ação tática mais visualizada durante os combates foi o ataque com 47.5 ± 5.5 vezes (p<0.01). "Mawashi geri" foi o ataque mais usado (p=0.01) pelos vencedores 71.4% quando comparado com os atletas derrotados 28.6%. Em conclusão o ataque "Mawashi geri" foi a decisão mais assertiva usada na categoria até 65 Kg.

ABSTRACT

SUMMARY OBJECTIVES: To analyze the association between physical activity during life and cardiovascular risk factors among adults. DESIGN: The sample was composed of 101 adults (59 men) between 30 and 50 years old, who were recruited from different gyms and from a University in Brasil. Participants were divided according to their engagement in sports in early life (self-reported) and current physical activity (pedometer) (sports participation during childhood/adolescence and currently active [n=26], sports participation during childhood/adolescence and currently inactive [n=26], and control [n=49]). Cardiovascular risk factors were measured, such as body fat (through DXA), HDL-C, triglycerides, HOMA index, systolic blood pressure, diastolic blood pressure, and C-reactive protein. We adopted the covariates of chronological age, sex, alcohol consumption, tobacco, and body mass index. General estimating equations were used, with p<0.05. RESULTS: After the adjustments of the final model, individuals engaged in sports during childhood and adolescence and inactive during adulthood presented lower body fat, when compared to participants persistently inactive (p<0.001). Participants persistently active presented lower body fat (p<0.001) and lower c-reactive protein (p=0.010) when compared to the control group. CONCLUSION: Early sports participation was associated with reduced body fat, and being physically active throughout life was associated with reduced body fat and C-reactive protein.


RESUMO OBJETIVO: Analisar a associação entre atividade física durante a vida e fatores de risco cardiovasculares entre adultos. DESIGN: A amostra foi composta por 101 adultos (59 homens) entre 30 e 50 anos, os quais foram recrutados em diferentes academias de ginástica e uma universidade brasileira. Os participantes foram divididos de acordo com o engajamento prévio (autorrelatado) e atual de atividade física (mensurada por pedômetro) (participação esportiva durante a infância/adolescência e prática atual [n=26], participação esportiva durante a infância/adolescência e ausência de prática atual [n=26] e controle [n=49]). Como fatores de risco cardiovasculares foram mensurados gordura corporal (por meio de DXA), HDL, triglicérides, índice Homa, pressão arterial sistólica e diastólica, além da proteína c-reativa. Foram adotadas como covariáveis: idade cronológica, sexo, consumo de álcool e índice de massa corporal. Equações gerais de estimativa foram utilizadas adotando p<0,05. RESULTADOS: Após os ajustes no modelo final, indivíduos engajados em esporte durante a infância e adolescência e inativos durante a idade adulta apresentaram menor gordura corporal quando comparados com participantes persistentemente inativos (p<0,001). Participantes persistentemente ativos apresentaram menor gordura corporal (p<0,001) e proteína c-reativa (p=0,010) quando comparados ao grupo controle. CONCLUSÃO: Prática esportiva prévia (durante infância e adolescência) foi associada com redução da gordura corporal e ser fisicamente ativo ao longo da vida foi associado à redução da gordura corporal e proteína c-reativa.

ABSTRACT

ABSTRACT BACKGROUND: Although the benefits of physical activity are clear, adherence to physical activity programs is a challenge, especially during transitional phases of life. OBJECTIVE: We aimed to identify adolescents who were more likely to drop out from physical activity and sports participation, from childhood to adolescence. DESIGN AND SETTING: This was a cross-sectional study on retrospective data regarding childhood activity among 803 Brazilian adolescents. The study was conducted at public schools in Londrina, Paraná, in 2011. METHODS: Habitual physical activity, sports participation during childhood, parental physical activity, socioeconomic status and perception of social relationships were self-reported. Cardiorespiratory fitness was estimated via a 20-m shuttle-run test and somatic maturation was estimated from the age at peak height velocity. RESULTS: Our results provided evidence that girls (physical activity: odds ratio, OR: 4.37 [95% confidence interval, CI: 1.86-10.3]; sports: OR: 2.65 [95% CI: 1.39-5.05]) and adolescents with low cardiorespiratory fitness (physical activity: OR: 1.77 [95% CI: 1.13-2.78]; sports: OR: 1.62 [95% CI: 1.15-2.26]) were more likely to drop out from active behaviors. Children with inactive mothers and inactive fathers (OR: 3.55 [95% CI: 1.12-11.3]) also showed a higher dropout rate from physical activity. Adolescents with negative perceptions of friendships (OR: 2.33 [95% CI: 1.21-4.47]) were more likely to drop out from sports. CONCLUSIONS: Higher dropout rates from active lifestyles during childhood were observed among girls and adolescents with low cardiorespiratory fitness. Parental inactivity and negative perceptions of friendships were also potential risk factors for discontinuation of childhood physical activity and sports.

ABSTRACT

Abstract Background: Cardiovascular disease (CVD) is the leading cause of death worldwide. Physical activity (PA) and appropriate diet, if adopted in childhood and adolescence, may reduce the CVD burden in later life. The Olympic Experimental Gymnasium (OEG) project was implemented to increase the PA levels of students by means of regular physical exercise and healthy eating habits. Objectives: To estimate and compare the prevalence of CVD risk factors in OEG schools versus regular schools (RSch) and to examine associations between the school environment and CVD risk factors. Methods: In this cross-sectional study with a comparator group, adolescents aged 12-13 years attending three OEG schools (n = 719) and three RSch (n = 394) were evaluated after one year of the ongoing program to estimate the prevalence of overweight, pre-hypertension/hypertension, altered glycemia, and lipid profile. An α level of 0.05 was set for statistical analysis. Results: RSch students had higher odds to have high blood pressure (OR 1.86, 1.36-2.54) and to be overweight (OR 1.49, 1.13-1.98) than OEG students. Glucose levels were not altered in most cases regardless of school type, and no differences were found in lipid profile. In the sensitivity analysis stratified by gender, girls from RSch were more likely to have high body mass index than boys. Conclusions: Exposure of adolescents to the OEG policies was positively associated with an important reduction in CVD risk factors, including high blood pressure and overweight.


Resumo Fundamento: A doença cardiovascular (DCV) é a principal causa de morte em todo o mundo. A atividade física (AF) e uma dieta adequada, quando adotadas na infância e na adolescência, podem reduzir a carga da DCV na fase adulta. O projeto "Ginásio Experimental Olímpico (GEO)" foi implementado para aumentar os níveis de AF dos estudantes por meio de AF regular e hábitos alimentares saudáveis. Objetivos: estimar e comparar a prevalência dos fatores de risco para DCV em GEOs versus escolas regulares (ERs), e avaliar associações entre o meio escolar e os fatores de risco cardiovascular. Métodos: Neste estudo transversal que incluiu um grupo de comparação, estudantes com idade entre 12 e 13 anos de três GEOs (n = 719) e três ERs (n = 394) foram avaliados após um ano de participação no programa para estimar a prevalência de sobrepeso, pré-hipertensão/hipertensão, e de glicemia e perfil lipídico alterados. Um α de 0,05 foi usado para inferências estatísticas. Resultados: Estudantes de ERs apresentaram maior chance de serem hipertensos (OR 1,86; 1,36-2,54) e apresentarem sobrepeso (OR 1,49; 1,13-1,98) que estudantes de GEOs. A glicemia não estava alterada na maioria dos casos, independentemente do tipo da escola, e não houve diferenças quanto ao perfil lipídico. Na análise de sensibilidade estratificada por gênero, estudantes do sexo feminino das ERs apresentaram maior probabilidade de apresentarem índice de massa corporal elevado que os do sexo masculino. Conclusão: A exposição dos adolescentes às políticas adotadas pelos GEOs associou-se positivamente com uma importante redução nos fatores de risco para DCV, incluindo hipertensão e sobrepeso.

ABSTRACT

El sedentarismo está aumentando en la Ciudad Autónoma de Buenos Aires (CABA). Es importante estudiar el ambiente construido que promueve la realización de actividad física (AF). Nuestro objetivo fue analizar la distribución del espacio verde (EV) apto para realizar AF, así como la oferta estatal de actividades deportivas gratuitas en la ciudad. Se realizó un estudio ecológico analizando y mapeando datos según fuentes e informes oficiales de CABA para 2015. Hicimos un análisis por número absoluto, superficie, densidad poblacional y valor promedio del metro cuadrado construido por comuna. Además, realizamos un análisis cualitativo según imágenes satelitales de la ciudad. La mediana de espacio verde apto para AF era de 2,6 m2/habitante (rango intercuartílico de 1,0 a 4,6). La menor cantidad estuvo en las comunas céntricas, más densamente pobladas, así como en la mayoría de las de menor valor del terreno (una de estas tenía buena cantidad de EV, pero con un ambiente construido que podría limitar la realización de AF). En cambio, en cuanto a las actividades deportivas gratuitas, a menor valor del terreno había mayor oferta. Estos resultados deben analizarse junto con condiciones ambientales y de seguridad para la planificación integral de la ciudad. (AU)


Sedentary lifestyle is increasing in Buenos Aires City (CABA). It is important to study the built environment that promotes physical activity (PA). Our objective was to analyze the distribution of the green spaces or urban open spaces (GS) suitable for PA, as well as the state offer of free sports activities in the city. We did an ecological study, analyzing and mapping data according to sources and official reports of CABA for 2015. We performed analyses by absolute number, area, population density and average value of the built squared meter for each district (comuna). In addition, we did a qualitative analysis according to satellite images of the city. The median of green space suitable for PA was 2.6 m2 / inhabitant (interquartile range 1.0 to 4.6). The smallest amount was in the central districts, more densely populated, as well as in most of the lower landvalue ones (one of these had a good amount of GS, but with a built environment that could limit the practice of PA). In contrast, regarding free sports activities, the lower the value of the land, the greater the state offer. These results must be analyzed along with environmental and safety conditions for an integral planning of the city. (AU)

ABSTRACT

Aim: To analyze the prevalence of sports practice patterns from childhood to adolescence, and to verify the association between sports practice and demographic factors (sex, age, and skin color), economic factors (maternal education and economic level) and current affinity for physical activities. Methods: A cross-sectional study was carried out with 1,112 adolescents (14-19 years) from southern Brazil. Sports practice patterns were composed of four combinations of sports practice from childhood to adolescence: (1) Practiced in both childhood and in adolescence; (2) Practiced in childhood but not in adolescence; (3) Did not practice in childhood but practices in adolescence; (4) Practice neither childhood nor in adolescence. Demographic, economic variables and current affinity for physical activities were evaluated by questionnaire. Multinomial logistic regression was used. Results: Of adolescents who practiced sports in childhood, 45.8% maintained the practice during adolescence (higher prevalence in males) and 14.1% gave up (higher prevalence in females). Of adolescents who did not practice sports in childhood, 27.6% started during adolescence (higher prevalence in males) and 12.5% maintained their childhood behavior (higher prevalence in females). Adolescents with low economic status who did not practice sports were more likely of not practicing this in both periods. Those who reported not enjoying physical activities were more likely of giving up sports in adolescence. Conclusion: Economic level and affinity for physical activities during adolescence are associated with sports practice patterns. Skin color, age, and maternal schooling are not associated with sports practice.(AU)

ABSTRACT

OBJECTIVES: In athletes, isolated electrocardiogram high voltage criteria are widely used to evaluate left ventricular hypertrophy, but positive findings are thought to represent normal electrocardiogram alterations. However, which electrocardiogram criterion can best detect left ventricular hypertrophy in athletes of various sport modalities remains unknown. METHODS: Five electrocardiogram criteria used to detect left ventricular hypertrophy were tested in 180 male athletes grouped according to their sport modality: 67% low-static and high-dynamic components and 33% high-static and high-dynamic components of exercise. The following echocardiogram parameters are the gold standard for diagnosing left ventricular hypertrophy: left ventricular mass index ≥134 g.m-2, relative wall thickness ≥0.42 mm, left ventricular diastolic diameter index ≥32 mm.m-2, septum wall thickness ≥13 mm, and posterior wall thickness ≥13 mm. Results for the various criteria were compared using the kappa coefficient. Significance was established at p<0.05. RESULTS: Fifty athletes (28%) presented with left ventricular hypertrophy according to electrocardiogram findings, with the following sensitivities and specificities, respectively: 38-53% and 79-83% (Perugia), 22-40% and 89-91% (Cornell), 24-29% and 90% (Romhilt-Estes), 68-87% and 20-23% (Sokolow-Lyon), and 0% and 99% (Gubner). The Perugia and Cornell criteria had higher negative predictive values for the low-static and high-dynamic subgroup. Kappa coefficients were higher for Romhilt-Estes, Cornell and Perugia criteria than for Sokolow-Lyon and Gubner criteria. CONCLUSION: All five evaluated criteria are inadequate for detecting left ventricular hypertrophy, but the Perugia, Cornell and Romhilt-Estes criteria are useful for excluding its presence. The Perugia and Cornell criteria were more effective at excluding left ventricular hypertrophy in athletes involved in a sport modality with low-static and high-dynamic component predominance.

ABSTRACT

La muerte súbita de un atleta o deportista siempre es un hecho trágico de gran exposición mediática, que genera gran impacto social. Afortunadamente es un hecho extremadamente raro que tiene una incidencia entre 1:80 000 y 1:200 000 atletas/año. Sus causas son distintas de acuerdo con la edad del atleta o deportista. En aquellos menores de 35 años predominan las miocardiopatías y las anomalías congénitas de las arterias coronarias; en los mayores de 35 años, la principal causa es la enfermedad coronaria aterosclerótica adquirida. Es común para ambos grupos la muerte súbita arrítmica con corazón estructuralmente normal. La tarea del equipo de salud que asiste a esta población reside en conocer y detectar las potenciales causas para restringir la participación en el deporte de los atletas en riesgo (prevención primaria). Pero también debemos estar preparados para asistir las muertes súbitas de los atletas en el campo de juego con programas de asistencia para emergencias cardiovasculares que incluyan desfibriladores externos automáticos (prevención secundaria). (AU)


The sudden death of an athlete is always a tragic event that leads to a great media exposure that generates great social impact. Fortunately, it is an extremely rare event with an incidence of 1: 80,000 to 1: 200,000 athletes per year. The causes vary according to the age of the athlete. In those < 35 years old, predominantly cardiomyopathies, and congenital anomalies of the coronary arteries. Whereas in the > 35 years, the main cause is generally acquired atherosclerotic coronary disease. In both groups, it is common to experience arrhythmic sudden death despite having a structurally normal heart. It is the task of the health teams that treat this population to know and detect potential causes to restrict participation in sport for the athletes at risk (primary prevention). But we must also be prepared to attend sudden deaths of athletes in the field with assistance programs for cardiovascular emergencies including automated external defibrillators (secondary prevention).

ABSTRACT

Dissection of cervical arteries constitutes a medical emergency. Although relatively rarely, activities classified as sports and recreation may be a cause of arterial dissection independently of neck or head trauma. The purpose of the present paper was to present a series of cases of cerebrum-cervical arterial dissection in individuals during or soon after the practice of these sports activities. Methods Retrospective data on patients with arterial dissection related to sports and recreation. Results Forty-one cases were identified. The most frequently affected vessel was the vertebral artery. A large variety of activities had a temporal relationship to arterial dissection, and jogging was the most frequent of these. This is the largest case series in the literature. Conclusion Arterial dissection may be a complication from practicing sports.


A dissecção das artérias cervicais é uma emergência médica. Embora de forma relativamente rara, certas atividades descritas como esportes e recreação podem ser a causa de dissecção arterial independentemente de trauma de crânio ou cervical. O propósito do presente estudo é apresentar uma série de casos de dissecção de artérias cérebro-cervicais em indivíduos durante ou logo após a prática destas atividades desportivas. Métodos Dados retrospectivos de pacientes com dissecção arterial relacionada à prática de esportes e recreação. Resultados Quarenta e um casos foram identificados. A artéria mais frequentemente afetada foi a vertebral. Uma grande variedade de atividades teve relação temporal com a dissecção arterial, sendo a corrida a mais frequente delas. Esta é a maior série de casos da literatura. Conclusão Dissecção arterial pode ser uma complicação da prática de esportes.

ABSTRACT

Objective: To examine the relationship between alcohol and tobacco use and sports in a national sample of secondary students. Methods: This cross-sectional study enrolled a representative sample of secondary students from public and private schools from all 27 Brazilian state capitals. Students were assessed in 2010 by a self-report questionnaire including questions on drug use and sport activity in the last month (n=13,872). Results: Subjects who played sports exhibited a higher frequency of alcohol use and heavy episodic drinking than their peers who did not play sports. Practices that were associated with higher odds of heavy episodic drinking in the last month included gym, weight training (adjusted odds ratio [aOR]: 2.0, 95% confidence interval [95%CI] 1.6-2.4), and soccer (aOR: 1.3, 95%CI 1.1-1.5). Fighting, martial arts, or capoeira were associated with smoking (aOR: 1.9, 95%CI 1.2-3.2). Conclusion: These results suggest a relationship between some sports preferences and a higher risk of alcohol or tobacco use among Brazilian secondary students. This relationship should be considered in preventive programs. .

ABSTRACT

Realizamos um mapeamento e uma breve descrição da produção sobre a temática "megaeventos esportivos" no XVIII Congresso Brasileiro de Ciências do Esporte. Utilizamos como fontes os anais e as transcrições das palestras proferidas no evento. Observamos que a palestra de abertura e as mesas enfatizaram mais questões relacionadas com os aspectos sociais, econômicos e culturais dos megaeventos do que questões relacionadas com o esporte em si. No caso das comunicações orais e pôsteres, a produção sobre a temática foi ínfima, considerando o número de trabalhos apresentados. Ressaltamos a necessidade de um maior investimento, por parte do corpo de pesquisadores do Colégio Brasileiro de Ciências do Esporte, no sentido de gerar conhecimentos que possam subsidiar a construção de legados esportivos para o país face à realização dos megaeventos que sediamos e estaremos sediando em breve.


We conducted a mapping and a brief description of the production on the theme "sports mega-events" at the XVIII Brazilian Congress of Sport Science in 2013. We used as sources the proceedings of the event and the transcripts of the lectures given at the occasion. We observed that the opening keynote and tables emphasized more issues related to social, economic and cultural aspects of mega-events than issues related to sport itself. In the case of oral communications and posters, the production on the subject was small, considering the number of presentations. We stress the need for greater investment on the part of the body of researchers from the Brazilian College of Sport Science, in order to generate knowledge that can help to construct a sporting legacy for the country, considering that it has hosted and will be hosting sport mega-events.
