Currently in the sports world, one of the prerequisites imposed by the organizers of sports sieves (selection of athletes) is the height, it becomes increasingly essential to play in clubs and teams worldwide. We noticed that teams base categories also suffer greatly from this height limitation. The objective of this research is to investigate the opinion of coaches, former coaches, players and former players and basketball players and volleyball on that possibility, or what to think about creating sub 1.80 m championships in men's tournaments. . This is a study of the qualitative and descriptive conducted with athletes and coaches volleyball and basketball courts, 6 volleyball players, six basketball players, volleyball players and a coach second technical basketball. We had the result of this work three main parameters: If athletes and coaches are in favor or not the creation of leagues, if there is any form of prejudice with the low in basketball and volleyball and opinions about the players lower in basketball and volleyball. Small players adhered to the idea of creating the league, high players were divided in high response and the coaches agreed saying that it grows with the Sports. Next step is the implementation, planning for these championships to assess the real possibilities of success of this initiative.

Voleyball is a sport that has gained an important contingent of public, achieving a growing visibility especially in recent years. Despite being a very democratic sport, as it is practiced by both men and women, it can be observed that there are differences when the analysis refers to who is in charge of the teams. So the purpose of this study was to analyze the presence of women in the country volleyball (coaches) from base categories to the professional adult, through a documental research. Data were collected from electronic documents, official websites and websites of federations teams. The results indicated that the number of women coaching volleyball athletes is minimal, revealing the difference between the professional treatment given to male and female genders. Therefore, it became clear that certain discrepancies are caused not only by lack of professionalism, but also by the cultural characteristics that still consider the place of women as domestic and not in the command of field sports

O contexto esportivo tem sido marcado por um numero crescente de torcedores, sendo esses algumas vezes apaixonados por esporte, ou meros curiosos que acompanham matérias jornalísticas, os mesmos torcedores que vibram nos momentos de vitória e vaiam nos momentos de derrota. Podemos dizer que essa torcida poderá desequilibrar o atleta a ponto de interferir em seu desempenho e levá-lo a uma ansiedade capaz de gerar outras fortes tensões, perdendo totalmente o controle da situação pela qual está passando. As equipes desportivas devem dar uma importância maior para a preparação psicológica dos atletas em função do modo como os fatores psicológicos, os agentes causadores de estresse e a baixa alto-estima causam interferência no cotidiano de um atleta. E essa preparação é sempre colocada em segundo plano quando comparada a preparação física, técnica e tática. Este estudo tem como objetivo analisar qualitativamente qual a influência que a torcida pode exercer sobre o desempenho de atletas de voleibol durante uma partida, seja ela disputada com a torcida incentivando ou tentando atrapalhar os jogadores. Em pesquisa documental (uma entrevista feita em 1997), cujos dados encontram-se armazenados no LEPESPE, Laboratório de Estudos e Pesquisas em Psicologia do Esporte, IB/UNESP, sob código DEF/UNESP/MCZ/97, coletados em campeonatos esportivos, no estado de São Paulo, incluindo jogos oficiais da Secretaria de Esportes e Campeonatos Esportivos Universitários por equipe de pesquisadores do laboratório, percebeu-se que tanto em turmas de treinamento, como em jogos entre classes ou entre escolas é que uma primeira preocupação fica mesmo por conta do jogar para ganhar, seguida da intenção de se fazer um bom papel, uma bela figura. Os depoimentos citados mostram que os alunos são breves espelhos de seus professores, quando são bem motivados com...(Resumo completo, clicar acesso eletrônico abaixo)

Volleyball is a sport in which the laterality dominant limb shows superior strength and coordination because of its preferential use. Asymmetrical tendencies during the landing after the jump when striking or blocking actions are predominant for most part of game (ARRUDA; EDUARDO, 2008). Adaptations include imbalance of forces in static and dynamic motions at the knee joint, which increases risk for injury. Also, asymmetries in balance control during jumping and landing associate with a general postural instability that can be observed during static balance tasks. The purpose of this study was to investigate relationship between unequal lower limb strength (muscle imbalance) and postural stability levels in volleyball athletes and non-athletes. Nine female volleyball athletes and 10 active non-athletes participated in this study. Four encouters with participants were scheduled: three encounters in the bodybuilding gymnasium to collect anthropometric measures (weight, height for BMI, thigh circumference, which provided an initial diagnosis about asymmetry), and to perform the isometric strength test (i.e., leg press using a load cell and a force transducer to calculate uni an bilateral strength). The last encounter was in the laboratory where a balance test on a force platform was administered under five test conditions, with three repetitions each: baseline (natural standing position), one-leg standing, right side, with full vision (D_CV), and blindfolded (D_SV), one-leg standing, left side, with full vision (E_CV), and blindfolded (E_SV). The stability levels were evaluated using the path length parameters which was based on the total displacement of the center of pressure (DTCP). . Both groups shows asymmetric strength levels between legs, with better performance for the right leg. An ANOVA three way using the DTCP for the CV condition, legs (D x E), trials (3) with repeated measures for the first two factors and with a between (three)...

The present study has for objective been to know the answers of performance indicators between different positions of volleyball and check for possible relationship between subjective perception referred by coach effort of volleyball athletes during training. Eleven athlete of the feminine sex, during eight weeks, 23 carried through sessions of training and eleven games, inferior members (Vertical Jump) and superiors had been evaluated by means of measures of explosive power in (Throw Medicine Ball), at the beginning and end of each week. For the verification of the subjective perceived of exertion it was used scales proposal for Foster (1998), to the end of each session of training. The collected data had been kept in computer file, producing information in the descriptive plan (measured central and dispersion) and the inferencial for the analysis of variance for the model with a factor complemented with the test of multiple comparisons of Tukey and linear correlation of Pearson. The results present as it has detached: i) the exercises specifics as content of bigger frequency in the training; ii) the test of vertical jump presented difference between the positions and, finally, iii) the subjective perceived of exertion between coach and athlete, he points that the trainer overestimates in 9,76% the perceived of the athletes. Such data are argued how much to the contents of the training as well as the load used in the interior of the process of preparation and monitoring of the training.

Este estudo investigou o efeito da interferência contextual (IC) na aquisição do serviço do voleibol em adolescentes com diferentes níveis de habilidade, considerando os testes de transferência imediato e retardado. A amostra foi composta por 56 meninas com idade entre 14 e 16 anos, distribuídas em quatro grupos de prática: aleatório com nível superior de habilidade (GAS), blocos com nível superior de habilidade (GBS), aleatório com nível inferior de habilidade (GAI) e blocos com nível inferior de habilidade (GBI). A tarefa motora consistiu dos serviços por baixo e por cima direcionados a alvos na quadra. Os resultados mostraram que o efeito da IC não foi observado nos grupos GAI e GBI, por outro lado, os grupos GAS e GBS apresentaram melhor desempenho no teste de transferência imediato. A ausência de diferenças significativas no teste de transferência retardado sugere que o efeito da IC pode ser temporário.

Pelo fato de o fracionamento da prática da cortada ser um tema polêmico que tem gerado inconsistências teóricas e práticas, o objetivo do presente estudo foi investigar quais métodos de fracionamento da cortada são utilizados por professores de Educação Física em diferentes fases profissionais no processo ensinoaprendizagem da cortada. Além disso, pretendeuse descrever as justificativas dos professores para a escolha dos métodos. A amostra foi composta por 36 professores de Educação Física com níveis distintos de experiência na área, os quais responderam a um questionário sobre o uso de métodos de ensino relativos ao fracionamento da cortada do voleibol. As maiores frequências de respostas favoráveis ao fracionamento foram fornecidas por professores em estágios iniciais da carreira, os quais alegaram que a complexidade da cortada é o motivo principal para o uso de tal procedimento
