ABSTRACT

Introducción: el judo es un deporte de combate cuya clasificación competitiva depende del peso corporal, lo cual está destinado a promover competencias parejas y equitativas en cuanto a capacidades físicas se refiere. El avance de las ciencias del entrenamiento y de la nutrición deportiva generó una mejora de la composición corporal en los deportistas, redundando en un aumento de los valores de masa muscular y en una disminución de la masa adiposa. El objetivo del estudio fue estimar la composición corporal de las personas que practican Judo participantes del campeonato nacional argentino del año 2021. Materiales y métodos: se realizó un estudio transversal descriptivo a los/as participantes del campeonato nacional de judo del año 2021. Fueron evaluados un total de 183 judocas (51 mujeres y 132 varones), según el protocolo de medición de la ISAK. Para la determinación de la composición corporal se utilizó el método de fraccionamiento anatómico de cinco componentes de Kerry Ross. Resultados: el promedio de las judocas fue de 30,5% para la masa adiposa y de 44,5% para la masa muscular; no se encontraron diferencias estadísticamente significativas en los distintos grupos de edad. Los varones obtuvieron un valor promedio de 22,4% para la masa adiposa y 49,1%para la masa muscular; en este caso se encontraron diferencias significativas entre los distintos grupos de edad, tanto para la masa adiposa como para la muscular y la masa ósea. Discusión: se necesitan más estudios con grupos estratificados en función de la división de peso corporal para poder establecer patrones de referencia específicos para el trabajo en ciencias del ejercicio y la nutrición. Conclusión: la optimización de la composición corporal de las personas que practican Judo redunda positivamente en la mejora de las capacidades físicas específicas. Los datos presentados constituyen una referencia específica de utilidad para la evaluación y seguimiento de las personas que practican Judo. La estratificación por grupos etarios y división de peso corporal permitirá delimitar mejor aún los valores de cada categoría de edad. Se considera relevante vincular la composición corporal con las pruebas físicas y los resultados deportivos, a fin de establecer un mejor perfil del judoca argentino. (AU)


Introduction: judo is a combat sport whose competitive classification depends on body weight, intended to promote even and equitable compe-titions in terms of physical abilities. Advances in the sciences of training and sports nutrition have led to an improvement in the body composition of athletes, resulting in an increase in muscle mass and a decrease in adipose mass. This study aimed to estimate the body composition of judo fighters participating in the 2021 Argentine National Championship. Materials and methods: we conducted a descriptive cross-sectional study of participants of the 2021 national judo championship. We evaluated 183 judokas (51 women and 132 men) applying the ISAK measurement protocol. We used the Kerry Ross five-component fractional anatomic method to determine body composition. Results: the average for female judo players was 30.5% for adipose mass and 44.5% for muscle mass; we found no statistically significant diffe-rences in the different age groups. The average value for males was 22.4% for adipose mass and 49.1% for muscle mass; in this case, we found significant differences between the different age groups for adipose mass and muscle and bone mass. Discussion: there is a need for more studies with stratified groups according to body weight division to establish specific reference standards for the work in exercise science and nutrition. Conclusion: the optimization of the body composition of female and male judo players has a positive effect on the improvement of specific physical capacities. The data presented constitute a relevant reference for the evaluation and follow-up of judokas. The stratification by age groups and body weight division will allow a better delimitation of the values of each age category. Linking body composition with physical tests and results is considered relevant to obtain a better profile of the Argentinian judo player. (AU)

ABSTRACT

El estudio de la función pulmonar en los deportistas de alto rendimiento es importante para el correcto manejo del entrenamiento y así evitar la frecuencia de la fatiga muscular respiratoria. Lo anterior reviste mayor importancia en el fútbol, debido al elevado esfuerzo desplegado por los deportistas en sus diferentes posiciones. Determinar el efecto del entrenamiento deportivo sobre la función pulmonar en deportistas de fútbol de la división sub-20 de un equipo deportivo local de la ciudad de Pereira. Se realizó un estudio descriptivo con 40 deportistas del equipo de fútbol de la división sub-20 de la ciudad de Pereira, Colombia. A todos se les realizó la prueba de espirometría, donde se identificó su función pulmonar teniendo relevancia en la relación VEF1/CVF. Los resultados encontrados refieren que la posición más frecuente en la población estudiada es la de volante, los parámetros recolectados de la relación VEF1/CVF muestran normalidad de su función pulmonar. Los deportistas de alto rendimiento realizan la ventilación a grandes volúmenes de aire corriente y menor frecuencia respiratoria, debido, al constante estímulo a que someten el centro respiratorio y al desarrollo de los músculos respiratorios aumentando la elasticidad tóraco-pulmonar mejorando la mecánica ventilatoria, favoreciendo por tanto la ventilación alveolar, por tal razón es importante incluir dentro del entrenamiento físico y de acondicionamiento, los ejercicios respiratorios.


The study of lung function in high-performance athletes is important for the correct management of training and thus avoiding the frequency of respiratory muscle fatigue. This is more important in soccer, due to the high effort deployed by athletes in their different positions. To determine the effect of sports training on lung function in soccer athletes from the U20 division of a local sports team in the city of Pereira. A descriptive study was carried out with 40 athletes from the soccer team of the sub20 division of the city of Pereira, Colombia. All of them underwent the spirometry test, where their lung function was identified, having relevance in the FEV1 / CVF relationship. The results found refer that the most frequent position in the study population is that of a steering wheel, the parameters collected from the FEV1 / FVC ratio show normal lung function. High-performance athletes perform ventilation with large volumes of running air and a lower respiratory rate, due to the constant stimulation of the respiratory center and the development of the respiratory muscles, increasing thoracopulmonary elasticity, improving ventilatory mechanics, favoring Both alveolar ventilation, for this reason it is important to include breathing exercises within physical training and conditioning.

ABSTRACT

ABSTRACT This study compared the frequency, number of goals and attack efficiency in temporal numerical superiority among winning and losing teams and among balanced and unbalanced matches in a junior men's water polo competition. Another analysed relationship was that between a balanced or unbalanced final score and the efficiency at scoring goals in numerical superiority in the winning teams' games. A total of 56 matches from the Pan-American Junior Men's Water Polo championship was analysed. The teams were categorised as losers or winners and the match results were classified as balanced or unbalanced. The chi-squared and Mann-Whitney tests were used for statistical treatment. There is no significant difference in the occurrence of numerical superiority between winners and losers (p = 0.25) despite the winners scoring more goals (p = 0.002) and being more efficient (p < 0.001). There is no significant difference in the occurrence of numerical superiority (p = 0.81) and goals (p = 0.03) in balanced and unbalanced matches. However, there tends to be a higher shot efficiency (p = 0.01) in unbalanced matches. A significant relationship exists (p = 0.04) between the winning teams' efficiency at scoring goals in a situation of numerical superiority and an unbalanced score.


RESUMO Esse estudo teve por objetivo comparar a frequência, a quantidade de gols e a eficiência do ataque em superioridade numérica temporal entre equipes vencedoras e perdedoras e entre partidas equilibradas e desequilibradas em competição júnior de polo aquático masculino. Também foi testada a relação entre a ocorrência do placar equilibrado ou desequilibrado com a eficiência em realizar gols em superioridade numérica nos jogos das equipes vencedoras. Foram analisadas 56 partidas do Campeonato Pan Americano Júnior de Polo Aquático Masculino. As equipes foram classificadas como perdedoras ou vencedoras e o resultado da partida como equilibrado ou desequilibrado. Teste Mann-Whitney e o qui-quadrado foram utilizados. Não há diferença significativa na ocorrência de superioridade numérica entre vencedores e perdedores (p = 0,25) apesar dos vencedores fazerem mais gols (p = 0,002) e serem mais eficientes (p < 0,001). Não há diferença significativa na ocorrência de superioridade numérica (p = 0,81) e de gols (p = 0,03) nas partidas equilibradas e desequilibradas. Entretanto, nas partidas desequilibradas encontrou-se maior eficiência no arremesso (p = 0,01). Foi encontrado relação significativa (p = 0,04) entre a eficácia das equipes vencedoras em realizar gol em superioridade numérica com o placar desequilibrado.

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

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

Objetivo: descrever a prevalência e os conhecimentos sobre o uso de protetores bucais personalizados (PBP) por atletas e professores. Métodos: estudo transversal descritivo realizado em 2016 no município de Piratini, RS. Os participantes eram atletas e professores de escolas e centros de treinamento. Foram coletados dados socioeconômicos, sobre conhecimentos, práticas, experiências e uso de PBP. Os dados foram analisados de forma descritiva com o programa EpiData Analysis, V2.2.3.187. Resultados: a amostra foi composta por 40 atletas e 7 professores, com idades entre 17 e 45 anos. A prevalência do uso de PBP entre os atletas foi de 32,5% (13) e 55% (22) não tinham conhecimento sobre PBP. Além disso, 77,5% (31) dos atletas e 100% (7) dos professores não saberiam indicar um profissional para confeccioná-los. Conclusão: o conhecimento sobre o uso de PBP é escasso, mas, contudo, há uma parcela de atletas que faz uso para a prática de esportes. Destaca-se a importância da necessidade de se investir em políticas de educação em saúde sobre protetores bucais em escolas, academias e centros de treinamento esportivo.(AU)


Objective: to describe the prevalence and knowledge about the use of personalized mouth protectors (PMP) by athletes and teachers. Methods: cross-sectional descriptive study carried out in 2016 in the Piratini/RS city. Participants were athletes and teachers from school and training centers. Socioeconomic data, knowledge, practices, experiences and use of PMP were collected. Data were analyzed in a descriptive with the EpiData Analysis program V2.2.3.187. Results: the sample consisted of 40 athletes and 7 teachers, aged between 17 and 45 years. The prevalence of PMP use among athletes was 32.5% (13) and 55% (22) were not knowledge of PMP. In addition, 77.5% (31) of the athletes and 100% (7) of the teachers did not know to indicate a professional to make them. Conclusion: the knowledge about the use of PMP is scarce and on the other hand, there is a portion of athletes that makes use for the practice of sports. It is important to emphasize the need to invest in health education policies on mouth protectors in schools, gyms and sports training centers.(AU)

ABSTRACT

ABSTRACT Differences in chronological age within an age group are known as Relative Age (RA), and their consequences to athletic performance are referred to as Relative Age Effect (RAE). The RAE among athletes is believed to affect their competitive success in several ways, even in adulthood. Thus, the objective of the present study was to investigate the RAE on all judo fighters competing nationally in 2013, by age category and competitive performance. A total of 862 male and 637 female athletes participated in this research. The chi-squared test was used for comparing observed and expected values among quartiles, adopting p < 0.05 as significance. A Bonferroni post hoc analysis was employed to identify where significant differences were (adjusted p < 0.00417). Results showed significant differences in the male under-15 category (Q2 in G1: OV = 17; EV = 9.7; p = 0.001) and male under-23 category (Q1 in G3: OV = 37; VE = 10.1; p < 0.0001). In conclusion, RAE was identified only in male athletes. However, there were major discrepancies between athletes born in the first semester and those born in the second semester.


RESUMO A diferença da idade cronológica em uma faixa etária é chamada de Idade Relativa (IR) e suas consequências no desempenho de atletas é chamada de Efeito da Idade Relativa (EIR). Acredita-se que o EIR entre atletas pode afetar o sucesso competitivo de diversas maneiras, até mesmo na idade adulta. Dessa forma, o objetivo do presente estudo foi investigar o EIR em todos os competidores de judô das competições nacionais do ano de 2013, fazendo-se a diferenciação por categorias etárias e o desempenho competitivo. Fizeram parte da presente investigação 862 atletas do sexo masculino e 637 do sexo feminino. O qui-quadrado foi empregado para comparar os valores observados e esperados entre quartis, adotando-se significância como p < 0,05. Uma análise post hoc de Bonferroni foi utilizada para identificar onde estavam as diferenças significativas (p ajustado < 0,00417). Os resultados mostraram diferença significativa nas categorias sub-15 masculino (Q2 em G1: VO = 17; VE = 9,7; p = 0,001) e sub-23 masculino (Q1 em G3: VO = 37; VE = 10,1; p < 0,0001). Em conclusão, o EIR foi identificado apenas em atletas do sexo masculino. Contudo, houve grande discrepância entre atletas nascidos no primeiro semestre e atletas nascidos no segundo semestre.

ABSTRACT

ABSTRACT The aims of the current study were: (a) to construct a reference table for burnout in soccer athletes of the U-20 category and (b) to verify the individual oscillations in the perception of these athletes in relation to burnout over three periods of the sports season. In total, 53 U-20 soccer athletes participated. The Athlete Burnout Questionnaire, Brazilian version, was applied to athletes during training, competition, and vacation periods of the sports season. A reference table was built for under-20 soccer athletes for each assessment period. Fluctuations were observed in the mean values of the total burnout frequency of the athletes during the 3 periods: training ( X ¯=1.35 ± 0.13 and X ¯=2.11 ± 0.19), competition ( X ¯=1.26 ± 0.13 and X ¯=2.27 ± 0.24), and vacation ( X ¯=1.27 ± 0.14 and X ¯= 2.18 ± 0.28). Based on this table and the individual classification of each athlete, it was observed that 32 athletes presented fluctuations in the perception of burnout during the sports season and 21 athletes did not present fluctuations in feelings of burnout during the three evaluation periods. The period with the highest number of athletes (n = 17) with a high level of burnout was the training period. It is concluded that it is not possible to establish a single and collective behavior regarding the fluctuations in burnout levels in athletes of the U-20 category during a sports season, and that the category reference table contributes to greater accuracy of the burnout evaluation in each period in the season.


RESUMO Os objetivos deste estudo foram (a) construir uma tabela de referência para o burnout em atletas de futebol da categoria sub-20 e (b) verificar as oscilações individuais na percepção destes atletas em relação ao burnout ao longo de três períodos da temporada esportiva. Participaram 53 atletas de futebol da categoria sub-20. Foi utilizado o Questionário de Burnout para Atleta nos períodos de treinamento, competição e férias durante uma temporada esportiva. Foi construída uma tabela de referência do burnout para atletas de futebol da categoria sub-20 para cada período avaliado. Foram encontradas oscilações nos valores médios da frequência do burnout total dos atletas durante os 3 períodos: treinamento( X ¯=1,35±0,13 e X ¯=2,11±0,19), competição ( X ¯=1,26±0,13 e X ¯=2,27±0,24) e férias ( X ¯=1,27±0,14 e X ¯=2,18±0,28).Baseado na tabela de referência e na classificação individual de cada atleta observou-se que 32 atletas apresentaram oscilações na percepção de burnout durante a temporada esportiva e 21 atletas não apresentaram oscilações nos sentimentos de burnout ao longo dos 3 períodos de avaliação. O período que teve o maior número de atletas (n=17) com alto nível de burnout foi o de treinamento. Conclui-se que não é possível estabelecer um comportamento único e coletivo a respeito das oscilações dos níveis de burnout em atletas da categoria sub-20 durante uma temporada esportiva e que a tabela de referência da categoria contribui para uma maior acertibilidade da avaliação do burnout em cada período da temporada.

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

RESUMO Esse estudo, de caráter documental, teve como objetivo investigar o volume e a aplicação de recursos públicos federais da CBHb no período entre 2008 e 2016, em relação as funções estabelecidas às entidades de administração do esporte, pelo Sistema Brasileiro do Desporto. Identificou-se as principais receitas da entidade e coletou-se documentos e prestações de contas (e.g. e-SIC, ME e COB) contendo os valores dos repasses e suas aplicações. Considerou-se apenas os valores executados pela entidade. No período, a CBHb executou R$ 129,6 milhões, que, embora segmentados, teve como a principal fonte os repasses de empresas estatais (41%). Em sua maioria, os recursos apresentaram interrupções e expressivas variações, mas que ao longo do período sofreram um aumento expressivo, justificado pela necessidade de impulsionar a preparação olímpica. Os dados apontaram para uma sobreposição no uso das políticas de financiamento quanto sua aplicação no esporte de elite e suas áreas de atuação. Identificou-se a ausência de uma política estruturada que garanta a oferta de atividades esportivas nas esferas educacionais e de participação que, consequentemente, alimentam o esporte de elite. Além disso, as políticas desenvolvidas se caracterizaram como ações que embora retardem o abandono do esporte, tendem a não estimular a renovação esportiva.


ABSTRACT The purpose of this documentary study was to investigate the amount and allocation of public funding directed to the CBHb in the period between 2008 and 2016, in relation to the functions established to sports federations, by the Brazilian System of Sports. The main revenues of the entity were identified, and documents and accounts (e.g. e-SIC, ME e BOC) that contained the amounts of the onlendings were collected. Were considered only the values executed by the entity. In the period, CBHb executed R $ 129.6 million, which, although segmented, had as its main source the resources coming from state-owned companies (41%). For the most part, resources presented interruptions and significant variations in their onlendings, however, over the period, they suffered a significant increase, justified by the need to boost the Olympic preparation. The data pointed to an overlap in the use of financing policies regarding its application in elite sport and its areas of activity. It was identified the absence of a structured policy that guarantees the provision of sports activities in other spheres that, consequently, feed the elite sport. The policies developed have been characterized as actions that, although delaying the abandonment of sports, tend not to stimulate sports renewal.

ABSTRACT

ABSTRACT The relative age effect (RAE) is a phenomenon that provides participation and performance advantages to athletes born in the first months of the year compared to other athletes within the same age category. The aim of the study was to investigate the effects of relative age in the in the major leagues of Brazilian basketball: Liga de Desevolvimento do Basquete (LDB), Liga de Basquetebol Feminino (LBF) and the Novo Basquete Brasil (NBB) considering the geographic region, the final classification of the teams, and the career period. The sample consisted of 831 athletes from the main leagues of Brazilian basketball during the 2014-2015 season. Information for the survey was obtained from the Brazilian Basketball Confederation website (www.cbb.com.br) and the National Basketball League website (www.lnb.com.br). The RAE was found in the Southeast and South LDB teams and in the Southeast NBB teams, and was not related to the teams' final classification. In addition, the RAE was reversed in the career consolidation phases of NBB athletes. We conclude that the RAE is present in LDB and NBB basketball players. An inverse RAE is observed in athletes aged 25-34 years, and there is an absence of this phenomenon in athletes who are at the final phase of their career.


RESUMO O efeito da idade relativa (EIR) refere-se a um fenômeno que proporciona vantagens de participação e desempenho aos atletas nascidos nos primeiros meses do ano, em relação aos demais atletas dentro de uma mesma categoria etária. O objetivo do estudo foi investigar o efeito da idade relativa na Liga de Desenvolvimento do Basquete (LDB), Liga de Basquete Feminino (LBF) e Novo Basquete Brasil (NBB), considerando a região geográfica, a classificação final das equipes e o período da carreira. A amostra foi constituída por 831 atletas das principais ligas do basquetebol brasileiro, temporada 2014-2015. As informações para a pesquisa foram obtidas através do site da Confederação Brasileira de Basketball (www.cbb.com.br) e do site da Liga Nacional de Basquete (www.lnb.com.br). O EIR foi encontrado nas equipes das regiões Sudeste e Sul da LDB, nas equipes do Sudeste do NBB e não apresentou relação com a classificação final das equipes. Além disso, o EIR mostrou-se invertido nas fases de consolidação da carreira nos atletas do NBB. Conclui-se que o EIR está presente nos basquetebolistas da LDB e NBB, sendo observado um EIR inverso nos atletas de 25 a 34 anos e ausência deste fenômeno naqueles que se encontram na fase final da carreira.

ABSTRACT

AIMS: To advance knowledge of long-term development of basketball players, this study investigated age and sex differences in game-related statistics which discriminate winners from losers in World Basketball Championships held after the 2010 rule change. METHODS: A total of 935 games from six categories (under-17, under-19 and open age for both men and women) were analyzed. All games were classified into three types (balanced, unbalanced and very unbalanced) according to point differential by a k-means cluster analysis. A discriminant analysis was performed to identify game-related statistics which discriminate winners from losers in each game type. An absolute value of a structural coefficient (SC) equal to or above 0.30 was considered relevant for the discrimination. RESULTS: In balanced games, assists discriminated winners from losers in open games (men, -SC- = 0.32; women, -SC- = 0.34), whereas successful free throws did so in under-17 games (men, -SC- = 0.30; women, -SC- = 0.31). Successful 2-point field goals discriminated winners from losers only in women's games (under-19, -SC- = 0.38; open, -SC- = 0.36). CONCLUSION: There were three novel findings in balanced games: 1) successful free throws but not assists discriminated winners from losers in under-17 games; 2) successful 2-point field goals discriminated winners from losers in women's games but not in men's games; and 3) discriminating power of successful 3-point field goals was extremely small in women's games. These results may be related to the new rules for the shot clock and the 3-point distance.(AU)

ABSTRACT

BACKGROUND: Cardiac vagal index (CVI) is supposedly higher in athletes and may differ between sports and/or between field positions. OBJECTIVE: To compare CVI: a) between elite football players vs. non-athletes and b) according to five football positions. METHOD: 242 football players of the first Brazilian/Angolan division were divided in five positions (N): goalkeepers (17), defenders (44), wingers (34), midfielders (87) and forwarders (60) and compared with 303 age-matched healthy non-athletes. CVI was estimated from a 4-second exercise test by quantifying the ratio of two cardiac cycle durations, before and at the end of a fast unloaded cycling exercise. RESULTS: Football players had resting and maximal heart rates of, respectively, 59 and 190 bpm and measured VO2max of 62.2 mL/(kg.min). Players and non-athletes showed similar CVI results (median-[P25-P75]) - 1.63-[1.46-1.84] vs 1.61-[1.41-1.81] (p = 0.22). Wingers tended to have a higher CVI (1.84-[1.60-1.99]), especially when compared to defenders (1.53-[1.41-1.72] (p = 0.01). There was a modest non-physiologically relevant association between VO2max and CVI (r = 0.15). CONCLUSIONS: Football players did not differ from non-athletes in CVI; however, among players, wingers were more often vagotonic, which may represent a hemodynamic advantage for match situations, where rapid heart rate transitions and faster oxygen delivery to muscles are required.


FUNDAMENTOS: O índice vagal cardíaco (IVC) é supostamente maior em atletas e pode diferir entre esportes e dentro do mesmo esporte. OBJETIVO: Comparar o IVC: a) entre futebolistas e não atletas e b) de acordo com cinco posições do futebol. MÉTODO: 242 jogadores da primeira divisão brasileira/angolana foram divididos em cinco posições (N): goleiros (17), zagueiros (44), laterais (34), meio-campistas (87) e atacantes (60) e comparados com 303 não-atletas saudáveis da mesma idade. IVC foi estimado a partir do teste de exercício de 4 segundos, quantificando a relação entre as durações de dois ciclos cardíacos - antes e ao final de uma pedalada rápida e sem carga RESULTADOS: As frequências cardíacas de repouso e máxima dos futebolistas foram, respectivamente, 59 e 190 bpm e o VO2max de 62,2 mL/(kg.min). Futebolistas e não-atletas mostraram resultados semelhantes de IVC (mediana- [P25-P75]) - 1,63- [1,46-1,84] vs 1,61- [1,41-1,81] (p = 0,22). Os laterais tenderam a ter maior IVC (1,84- [1,60-1,99]), especialmente quando comparados aos defensores (1,53- [1,41-1,72] (p = 0,01). Houve uma modesta associação fisiologicamente irrelevante entre VO2max e IVC (r = 0,15). CONCLUSÕES: jogadores da elite do futebol não diferem de não-atletas em IVC; entretanto, entre eles, os alas se mostraram mais frequentemente vagotônicos, o que pode representar uma vantagem hemodinâmica para situações de jogo, onde são necessárias transições rápidas da frequência cardíaca e um aporte mais rápido de oxigênio para os músculos ativos.

ABSTRACT

Abstract: Objectives: To examine both body mass index (BMI) status and waist circunference (WC) in a large international sample of adult Special Olympics participants from Latin America. It also explored the association of age and sex with obesity in this population. Materials and methods: BMI and WC records from a total of 4174 (2683 male and 1491 female) participant records from the Special Olympics International Health Promotion database were examined. Results: The prevalence of overweight and obesity was quite high (i.e. > 40%), but generally lower than studies involving adults with intellectual disabilities from Europe and the USA. Chi-square analyses revealed that both increasing age and being female significantly predicted levels of overweight, obesity, and WC. Conclusions: These results suggest that efforts need to be made to prevent and reduce rates of overweight and obesity among Latin American Special Olympics participants, particularly women.


Resumen: Objetivos: Examinar tanto el estado de índice de masa corporal (IMC) como la circunferencia de cintura (WC) en una muestra significantemente grande de participantes internacionales de Olimpiadas Especiales de América Latina. También este estudio exploró la asociación de la edad y el género con la obesidad en esta población. Material y métodos: Se examinaron los registros de IMC y WC de un total de 4174 (2683 hombres y 1491 mujeres) del banco de datos de la Promoción Internacional de la Salud de Special Olympics (Special Olympics International Health Promotion). Resultados: El predominio de sobrepeso y obesidad fue bastante alta (es decir, > 40%), pero generalmente menor en comparación con los estudios con adultos con discapacidad intelectual de Europa y los Estados Unidos. El análisis Ji cuadrada reveló que tanto el aumento de la edad y ser mujer predijo significativamente los niveles de sobrepeso, obesidad y WC. Conclusiones: Estos resultados sugieren que hay que hacer esfuerzos para prevenir y reducir las tasas de sobrepeso y obesidad entre los participantes de las Olimpiadas Especiales de América Latina, particularmente las mujeres.

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

ABSTRACT Objective: To assess the dietary intake and overall diet quality of female soccer players before the competitive games. Methods: This descriptive and cross-sectional study included 21 women aged 20.8±4.5 years from a professional soccer team. Their nutritional status and dietary adequacy during the training period, before competition season, were assessed. Dietary intake was assessed by three 24-hour recalls, one food frequency questionnaire, and the Healthy Eating Index, an overall diet quality index based on food group intake. Results: The athletes have shown proper nutritional status, but a diet deficient in energy due largely to low carbohydrate intake. On the other hand, the intakes of protein, fatty acids, and sodium were above the recommended intakes, even for athletes. Diet quality assessment by the Healthy Eating Index - 2010 resulted in a mean score of 54.6 points of a maximum of 100, indicating a need of improving the overall diet quality. Conclusion: The study found that the dietary patterns of female football players were both quantitatively and qualitatively inappropriate. A nutritional intervention is indicated to improve diet quality, with the inclusion of various foods, such as whole grains, fruits, vegetables, dairy products, and better protein quality, along with a reduction in saturated fats, sodium, and added sugar.


RESUMO Objetivo: Avaliar a ingestão alimentar e a qualidade nutricional global da dieta de jogadoras de futebol antes dos jogos competitivos. Métodos: Estudo descritivo transversal realizado com 21 mulheres, de 20,8±4,5 anos de idade, de uma equipe de futebol profissional. Elas foram avaliadas em relação ao seu estado nutricional e adequação da dieta durante o período de treinamento, antes da temporada de competição. A ingestão alimentar foi avaliada por três recordatórios de 24 horas, um questionário de frequência alimentar e pelo Índice de Alimentação Saudável (2010), um índice de qualidade global da dieta baseada no consumo de grupos de alimentos. Resultados: Verificou-se que as atletas apresentavam estado nutricional adequado, mas tinham uma dieta deficiente em energia devido, em grande parte, à ingestão insuficiente de carboidratos. Por outro lado, o consumo de proteínas, ácidos gordos e de sódio estavam acima da recomendação, mesmo para atletas. A avaliação da qualidade da dieta pelo Índice de Alimentação Saudável (2010) mostrou uma pontuação média de 54,6 de 100, exibindo a necessidade de melhoria da qualidade da dieta. Conclusão: O estudo mostrou padrões alimentares inadequados, tanto quantitativa como qualitativamente, em jogadoras de futebol. A intervenção nutricional é indicada para melhorar a qualidade da dieta com a inclusão de vários itens alimentares, como cereais integrais, frutas, legumes, produtos lácteos e melhor qualidade de proteínas, acompanhado de redução de gorduras saturadas, sódio e açúcar.

ABSTRACT

ABSTRACT Objective: To evaluate the impact of an Interdisciplinary Food, Nutrition and Health Education Program on nutrition knowledge, intention to change eating behavior, and body dissatisfaction of adolescent volleyball players. Methods: The sample consisted of 10 female volleyball players from the juvenile category of the city of Santos, São Paulo, Brazil, who participated in a program with eight monthly meetings (one discussion group followed by six educational activities and one final discussion group for evaluation). Results: Nutrition knowledge, body perception, intention to change eating behavior, eating attitudes and practices were investigated using questionnaires and discussion groups before and after the athletes' participation in ludic activities designed to address nutrition strategies for athletic performance and healthy eating, and how to deal with pressure for results and self-image. Nutrition knowledge improved from 57.0%±9.9 to 63.0%±11.8 (p=0.03) of correct answers. The mean body distortion score did not change (70.0±14.9 versus 76.5±22.4, p=0.235). Six athletes advanced in their intention to change eating behavior. Positive food practices were reported during the program and the identified discourses indicated the intention of changing the daily eating habits in the future. Conclusion: The program had a positive impact on nutrition knowledge and intention of changing eating behavior; however, for other issues, especially involving emotional aspects, further interventions should be planned.


RESUMO Objetivo: Avaliar o impacto de um Programa Interdisciplinar de Educação Alimentar, Nutricional e em Saúde sobre o conhecimento nutricional, a intenção de mudança de comportamento alimentar e a insatisfação corporal de jogadoras de voleibol adolescentes. Métodos: A amostra foi composta por 10 atletas de voleibol, jogadoras da categoria juvenil da cidade de Santos, SP, que participaram do programa composto por oito encontros mensais (um grupo de discussão seguido por seis atividades educacionais e um grupo de discussão final para avaliação). Resultados: Conhecimento nutricional, percepção corporal, intenção de mudança de comportamento alimentar, atitudes e práticas alimentares foram investigadas por questionários e grupo de discussão antes e depois da participação das atletas nas atividades lúdicas, as quais abordaram estratégias nutricionais para desempenho esportivo, alimentação saudável, lidar com pressão por resultados e percepção corporal. O conhecimento nutricional aumentou de 57,0% ±9,9 para 63,0% ±11,8 (p=0,03) de acerto. Não houve diferença no escore de distorção corporal (70,0±14,9 versus 76,5±22,4, p=0,235). Seis atletas avançaram na intenção de mudança de comportamento alimentar. Modificações positivas nas práticas alimentares foram relatadas durante as atividades e os discursos identificados apontam intenções de futuras mudanças nos hábitos alimentares diários. Conclusão: O programa teve impacto positivo em aumentar o conhecimento nutricional e mudança de comportamento alimentar; porém, para outros aspectos, principalmente envolvendo questões emocionais, outras intervenções devem ser planejadas.
