O handebol caracteriza-se por transições rápidas entre ações ofensivas e defensivas durante o jogo com objetivo de marcar gols. O nível de conhecimento tático declarativo (CTD) e de aptidão física (APF) do atleta pode influenciar o desempenho. Este estudo objetivou-se em analisar a correlação entre o nível de CTD e de APF de atletas de handebol. A população amostra envolveu 16 atletas, com idade entre 16.69 (±0.60) anos, sexo masculino, escolhidos por conveniência. Utilizamos os protocolos do Projeto Esporte Brasil e CTD. O índice de massa corporal do grupo analisado apresentou média de 24.05 (± 5,71) apontando eutrofia e a relação cintura e estatura a média foi 0.82 (± 0,13), zona saudável. Em relação a APF dos atletas, identificamos níveis fraco para agilidade (100%), muito bom para flexibilidade (62.5%), bom para força de membros inferiores, (62.5%) muito bom para força de membros superiores (50%), bom para resistência cardiorrespiratória (68.8%), razoável para resistência muscular localizada (37.5%) e fraco para velocidade (100%). O nível de CTD apresentou nível fraco e em evolução com média de 2,50 (± 1,03). Os componentes da APF e CTD não apresentaram correlações significativas. Ademais, os resultados foram promissores, porém, estão aquém dos padrões de excelência, necessitando melhorias.

O objetivo foi comparar o estado de humor de jovens atletas de voleibol de praia em função do resultado do jogo. Participaram do estudo 16 atletas (idade = 17 ±2,44 anos). Todos foram submetidos a uma competição simulada, seguindo as regras oficiais. Previamente, os atletas respondiam (30 minutos antes de jogar), ao Perfil de Estados de Humor (POMS), divididos nas dimensões tensão, depressão, raiva, vigor, fadiga e confusão. Os dados foram comparados utilizando o teste U de Mann-Whitney, de acordo com o desempenho (vencedor e perdedor). Além disso, calculou-se o coeficiente de correlação bisserial por ponto (Tau de Kendall) e determinação (т-quadrado), para as variáveis com diferença significante, adotando significância 5%. Independentemente do desempenho o perfil de humor observado foi “iceberg”. Além disso, verificou-se diferença significante na dimensão “confusão” (Vencedor= 2,00 Vs. Perdedor= 5,50; U= 13,00; p= 0,043; d= 1,151). Adicionalmente, o coeficiente de correlação e determinação foi т= 0,457 (p= 0,043) e т2= 0,208, respectivamente. Independente do resultado, o perfil de humor 30 minutos antes do jogo foi “iceberg”. Para mais, a subescala “confusão” foi o principal indicador de desempenho psicológico identificado, explicando ~20% a variação entre vencer e perder.

This study aims to investigate the aftereffect of a six-week virtual reality environment training on dynamic and static postural stability in athletes participating in random intermittent dynamic type sports. The pretest and posttest study designs were chosen to conduct this study. Twenty-four male athletes were selected for the study. Participants participated in a six-week virtual reality environment training program three times a week for a session of forty-five minutes. The virtual reality environment was created using CAREN's integrated virtual reality system with Motek's D-flow application. The postural stability was assessed using a stadiometer. Assessments were performed before and after six weeks of training. A paired sample t-test was used to determine differences between pretest and posttest outcome measures. The improvement can be seen as an effect of virtual reality environment training intervention. Statistically significant differences were observed between pretest and posttest for dynamic and static anteroposterior and mediolateral postural stability at 20 and 40 levels of difficulty. The virtual reality environment training helps to improve performance by assessing and optimizing the training load in the process of improving the performance of athletes participating in random intermittent dynamic type sports.

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. [ABSTRACT FROM AUTHOR]

Introdução e objetivo: A pré-temporada é importante para o desenvolvimento das capacidades físicas dos atletas, sobretudo a potência aeróbia. Contudo, nem sempre se avaliam os resultados das intervenções realizadas neste período. Nosso objetivo foi avaliar o efeito da pré-temporada na potência aeróbia, analisada pelo pico de velocidade (PV) obtido em um teste incremental de campo. Materiais e métodos: Doze atletas homens (idade: 21,8 ± 3,3 anos; estatura: 178,5 ± 7,1 cm; massa corporal: 70,1 ± 5,9 kg; Índice de Massa Corporal: 22,0 ± 1,8 kg/m2) da categoria profissional (Segunda divisão brasiliense) realizaram um teste progressivo intermitente (Teste de Carminatti) no início e no final da pré-temporada, para mensuração do PV. Os dados descritos em termos de média ± desvio-padrão, o PV inicial e final foi comparado utilizando o Teste t pareado e o tamanho de efeito (TE) - d de Cohen. A menor diferença importante foi utilizada para analisar a melhora individual dos atletas. Resultados: Observou-se um aumento significativo do PV no final da pré-temporada, quando comparada ao início (15,3 ± 1,0 km/h vs 14,7 ± 0,8 km/h; p=0,002; TE: 0,7). Individualmente, 25,0% dos atletas tiveram uma melhora considerada grande (>0,91 km/h), 16,7% tiveram uma melhora moderada (>0,45 km/h), 33,3% tiveram uma pequena melhora (>0,15 km/h) e 25,0% tiveram alterações pequenas demais para serem consideradas importantes (≤0,15 km/h). Conclusão: Ao final da pré-temporada o PV do time aumentou significativamente, contudo, houve muita heterogeneidade nas respostas. Uma parte dos atletas alcançaram melhoras expressivas, enquanto outros tiveram alterações insignificantes.

A penalidade máxima no futebol é um momento importante do jogo, e frequentemente torna-se alvo de polêmicas no contexto esportivo. Por outro lado, a crescente tecnológica e as análises de desempenho têm favorecido as tomadas de decisão por parte da comissão técnica e dos atletas. Desta forma, o objetivo desta pesquisa foi analisar o desempenho dos jogadores nas penalidades máximas ocorridas ao longo das nove últimas edições do campeonato brasileiro de futebol. No total foram analisados 3.420 jogos, com 875 cobranças de penalidades máximas. Na análise descritiva os dados foram resumidos em frequências relativas e absolutas, e para o comportamento das variáveis foi utilizado o coeficiente de correlação de Pearson. Todas as análises foram realizadas no programa Graph Pad Prism. Os resultados mostram um maior volume de cobranças para os times mandantes, sendo que em seis temporadas os visitantes converteram mais as oportunidades em gols. Ao longo das edições analisadas houve pouca variação nas cobranças convertidas, defendidas e desperdiçadas, com moderada redução (r=-0,59) nas penalidades desperdiçadas pelas equipes mandantes.

Introdução e objetivo: A alta intensidade incluída no futebol, exige demandas elevadas dos componentes físicos e motores do indivíduo que o pratica. Para identificar indicadores de aptidão aeróbia, como o limiar de lactato, limiar anaeróbio, lactato mínimo e a máxima fase estável de lactato, tem se avaliado os índices de resposta da concentração de lactato sanguíneo sobre o exercício. O estudo objetivou analisar a concentração de lactato sanguíneo e a percepção subjetiva de esforço de atletas amadores de futebol. Materiais e métodos: Fizeram parte do estudo, atletas jovens de 19 a 27 anos praticantes de futebol amador. A amostra foi composta por 7 atletas que, em média, possuíam 13 anos de prática esportiva. As coletas sanguíneas, para determinação da concentração de lactato, foram realizadas em diferentes etapas da partida, e foram utilizadas as escalas de PSE 6-20 e PSE 0-10. Resultados: Um achado interessante deste estudo foi a forte correlação de 0,78 (p=0,03) encontrada entre a média da tabela de Borg 6-20 aplicada no final imediato da primeira e segunda etapa, com a tabela de Borg 0-10 aplicada 15 minutos após o final da partida. Discussão: Embora o resultado sobre a concentração de lactato não tenha sido significativo, houve diminuição deste parâmetro, do fim da primeira para o fim da segunda etapa. Conclusão: Diante dos resultados encontrados, o estudo afirma que tanto a PSE 0-10 quanto a PSE 6-20, podem ser utilizadas como instrumento de análise da intensidade de exercício em praticantes de futebol amador.

O presente estudo, tem como objetivo analisar o desempenho tático de jogadores de futebol da categoria sub 17 nas diferentes fases do jogo. A pesquisa foi realizada com 24 jovens atletas da categoria sub 17 de um clube de futebol amador de uma cidade da fronteira oeste do Rio Grande do Sul. O estudo caracterizou-se como descritivo de caráter quantitativo. Como instrumento para análise de dados do desempenho tático processual utilizou-se o sistema FUT-SAT, empregou-se na análise do desempenho tático processual a estatística descritiva (frequência, percentual, média e desvio padrão) e a inferencial (teste Qui-quadrado), com nível de significância de 5%. Para a realização destas análises recorreu ao software Statistical Package for Social Science (SPSS). Com base nos dados encontrados, concluiu-se que os atletas meio-campistas têm maiores ações dos princípios táticos ofensivos, assim como, os defensores nos princípios táticos defensivos. Pode se inferir também, que os principais princípios táticos ofensivos desenvolvidos foram a Penetração pelos atacantes e os defensivos a Contenção pelos defensores.

Introdução: Dentre os esportes mais praticados e com exímio destaque em todo o mundo, o futebol é um deles. Nesse sentido, realizar análises de desempenho dos fatores técnicos, auxilia um melhor desenvolvimento da leitura de jogo, melhorando os pontos fracos da equipe para alcançar resultados mais expressivos. O time vencedor pode conquistar a vitória simples ou com goleada. Não existem muitos estudos que realizam a análise de desempenho comparativa entre essas situações. Objetivo: O objetivo do estudo foi comparar as variáveis técnicas de finalizações, posse de bola, passes certos, passes errados e faltas das equipes que venceram por goleada e das equipes que venceram por diferença inferior a quatro gols. Materiais e Métodos: Em meio as inúmeras competições de futebol realizadas, optou-se analisar a Champions League, por ser um dos campeonatos de melhor nível técnico e grande visibilidade no mundo. Foram analisados 125 jogos da temporada 2015/2016 deste campeonato, considerando-se apenas as partidas em que houve vencedor. Resultado: Após a análise de todas as variáveis técnicas, constatou-se que as equipes vencedoras por goleada realizaram mais finalizações, faltas, passes certos e tiveram maior posse de bola do que o time adversário. Conclusão: Portanto, concluiu-se que as equipes que venceram por goleada apresentaram melhores resultados nos indicadores técnicos comparado às equipes que venceram seus jogos sem goleadas.

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. [ABSTRACT FROM AUTHOR]

This study aims to investigate the aftereffect of a six-week virtual reality environment training on dynamic and static postural stability in athletes participating in random intermittent dynamic type sports. The pretest and posttest study designs were chosen to conduct this study. Twenty-four male athletes were selected for the study. Participants participated in a six-week virtual reality environment training program three times a week for a session of forty-five minutes. The virtual reality environment was created using CAREN's integrated virtual reality system with Motek's D-flow application. The postural stability was assessed using a stadiometer. Assessments were performed before and after six weeks of training. A paired sample t-test was used to determine differences between pretest and posttest outcome measures. The improvement can be seen as an effect of virtual reality environment training intervention. Statistically significant differences were observed between pretest and posttest for dynamic and static anteroposterior and mediolateral postural stability at 20 and 40 levels of difficulty. The virtual reality environment training helps to improve performance by assessing and optimizing the training load in the process of improving the performance of athletes participating in random intermittent dynamic type sports.
