The purpose of this study was to investigate the relationship of six selected volleyball skill tests to actual volleyball game performance. The six skill test items were administered to 64 subjects, who were all members of a college level introductory volleyball course. Based on the ratings of a panel of experts, subjects were rated during game play as good, average, or poor performers. The stepwise discriminant analysis was used to analyze the relationship between skill tests and game performance. Four of the six skill tests were identified as significantly contributing to group membership. These tests, in order of the magnitude of their standardized discriminant function coefficients were: 1. Brumbach Serve Test, 2. AAHPER Wall Volley test, 3. AAHPERD Wall Spike Test, and 4. AAHPERD Serve Test. It was concluded that a volleyball skill test battery consisting of these four items would objectively measure volleyball playing ability and discriminate between players of various skill levels. The results of this test battery could be used for classification, diagnosis, motivational purposes, and grading.

O objetivo desse trabalho foi observar a evolução do modelo de jogo entre as categorias de base do voleibol feminino, analisando como cada categoria conquista o ponto e a como as variantes das ações de jogo que antecedem o ataque influenciam no seu desempenho no complexo I. Foram analisados três jogos das quatro melhores equipes classificadas da categoria infantil, infanto-juvenil e juvenil feminino, participantes do quadrangular final do Campeonato Metropolitano de São Paulo em 2009 organizado pela FPV. A coleta de dados foi realizada pelo sistema de vídeo. A análise dos dados comportou a estatística descritiva, pela obtenção de frequências e porcentagens, e a estatística inferencial pelo recurso ao Qui-quadrado e ao Phi de Cramer, no sentido de verificar a possível relação de dependência entre as vaiáveis do estudo. Através da análise descritiva observamos que a categoria infantil conquista mais pontos com o erro do adversário e as categorias infanto-juvenil e juvenil conquistam mais pontos com a ação de ataque. Com o avanço de categoria observamos uma tendência de aumento na recepção perfeita, na utilização do levantamento com toque em suspensão, do ataque contra um bloqueio duplo quebrado, na realização do ataque pela zona 2 bem como, um aumento na ocorrência dos ataques de 1º e 2º tempo e do ataque ponto. Assim como, uma diminuição na utilização do toque sem salto para o levantamento, dos ataques contra um bloqueio duplo compacto, da utilização dos ataques de 3º tempo e dos ataques que proporcionam a continuação do rally. Pela análise inferencial observamos uma relação de dependência estatisticamente significante do resultado do ataque com o resultado da recepção, a zona de levantamento, a técnica de levantamento, o resultado do levantamento, bem como com a zona de ataque, o tempo de ataque e tipo de ataque para todas as categorias / The main purpose of this study was to determine game model evolution on female volleyball under-age divisions. It was analyzed how each category wins the point and how the game actions that occur before the attack affects the performance on complex I. We analyzed three games of the four best ranked female teams in infantil, infanto-juvenil and juvenil divisions, participants of the city of São Paulo Championship in 2009. The data base was captured using video system. Data analysis included descriptive statistics, by obtaining frequencies and percentages, and inferential statistics by using chi- square and Phi Cramer, in order to verify the possible relationship of dependency between the study variables. Descriptive analysis revealed that the infantil division obtain more points with the errors of the opponent and the infanto-juvenil and juvenil divisions obtain more points with the attack. As players advance through the age divisions, there is a trend toward increasing the occurrence of perfect receptions, the use of jump sets, the attack against a broken double block, the attack in zone 2 as well as an increase in the occurrence of attacks of 1st and 2nd tempo and the attack point. Moreover, we observed a decrease in the use of overhead set without jump, attack against a compact double block, the use of 3rd tempo attack and attack that provide continued rally. For the inferential analysis we observed a statistically significant relationship of dependency between attack result and the serve reception result, the set zone, set technique, the result of the set, as well as the attack zone, the attack tempo and type of attack for all categories

O efeito da potencialização pós-ativação (PPA) tem sido estudado, mas a sua aplicação no desempenho de atletas é muito controversa. Estudos descrevem a possibilidade de que a PPA possa compensar o mecanismo de fadiga, aumentando a taxa de desenvolvimento de força e melhorando a potência muscular. O objetivo deste estudo foi avaliar os efeitos agudos e crônicos de um treinamento pliométrico com e sem indução da PPA na potência muscular de membros inferiores em atletas de voleibol. A amostra foi composta por 16 atletas de voleibol masculino participantes da Superliga Nacional, divididos em grupo pliométrico (GPLIO) e grupo PPA (GPPA). O grupo pliométrico foi submetido a um treinamento de pliometria e o grupo PPA acrescentou ao treinamento pliométrico uma rotina de treinos que estimularam o mecanismo de PPA. O período de treinamento foi de 4 semanas com 2 sessões semanais. Durante a avaliação do pré e pós-treinamento para a determinação dos efeitos crônicos, foi mensurada a potência muscular dos membros inferiores através do salto vertical counter movement jump (CMJ), conforme protocolo sugerido por Bosco (1994), em uma plataforma de força, e contração voluntária máxima para a musculatura da articulação do joelho em um equipamento isocinético. Na avaliação pré e pós-teste para a determinação do efeito agudo, foi utilizado um tapete de contato para obtenção da altura de salto vertical CMJ. Para análise estatística foi utilizado o teste de equações de estimação generalizadas (GEE) no fator tempo e no fator grupo para determinar os efeitos do treinamento em cada grupo (GPLIO e GPPA). Os resultados referente aos efeitos agudos indicam a interação grupo*tempo para o grupo PPA significativa de p<0,001 (38,26 cms / 44,51 cms) do período pré-treinamento para o período de treinamento e de p=0,002 (38,26 cms /44,07 cms) do período pré para o pós treinamento. Ainda observamos que o grupo PPA obteve altura de salto significativamente melhor ao grupo PLIO, tanto no período de treinamento (44,51 cms/35,38cms) como no pós-treinamento pliométrico (44,07cms / 39,32 cms). Quanto aos efeitos crônicos, os resultados demonstraram não haver diferença significativa para as variáveis de torque isocinético. No que diz respeito à altura e potência de salto após o treinamento crônico foi observada diferença significativa nos dois grupos do período pré para o pós-treinamento, não havendo diferença entre os grupos. Concluímos que o treinamento pliométrico com indução de PPA melhora os efeitos agudos do salto vertical, tanto durante o treinamento como até 80 minutos após o treinamento pliométrico. Já no que diz respeito aos efeitos crônicos da indução ou não de PPA no treinamento pliométrico, os resultados indicam não haver diferença significativa no torque isocinético dos músculos extensores do joelho, porém na altura de salto CMJ e potência os resultados indicam que os dois modelos de treinamento têm uma resposta semelhante. / The effect of post-activation potentiation (PPA) has been studied, but its application in the performance of athletes is very controversial. Studies have described the possibility that PPP can compensate for the fatigue mechanism, increasing the rate of strength development and improving muscle power. The objective of this study was to evaluate the acute and chronic effects of a plyometric training with and without PPA induction on lower limb muscle power in volleyball athletes. The sample consisted of 16 male volleyball players participating in the National Superliga, divided into plyometric group (GPLIO) and PPA group (GPPA). The plyometric group underwent a plyometrics training and the PPA group added to the plyometric training a routine of training that stimulated the PPA mechanism. The training period was 4 weeks with 2 weekly sessions. During the pre and post-training evaluation for the determination of the chronic effects, the muscular power of the lower limbs was measured through the vertical jump movement movement (CMJ), according to a protocol suggested by Bosco (1994), on a force platform, And maximal voluntary contraction for the musculature of the knee joint in an isokinetic equipment. In the pre and post-test evaluation for the determination of the acute effect, a contact mat was used to obtain the vertical jump height CMJ. For statistical analysis, the test of generalized estimation equations (GEE) in the time factor and in the group factor was used to determine the effects of the training in each group (GPLIO and GPPA). The results for the acute effects indicate the group*time interaction for the PPA group significant of p<0.001 (38.26 cms / 44.51 cms) of the pre-training period for the training period and p=0.002 (38, 26 cm / 44.07 cm) from the pre and post training period. We also observed that the PPA group had a significantly better jump height in the PLIO group, both in the training period (44.51 cm / 35.38 cm) and in the plyometric training (44.07 cm / 39.32 cm). Regarding the chronic effects, the results showed no significant difference for the isokinetic torque variables. Regarding the height and jumping power after the chronic training, a significant difference was observed in the two groups from the pre-post-training period, with no difference between the groups. We conclude that plyometric training with PPA induction improves the acute effects of vertical jump, both during training and up to 80 minutes after plyometric training. Regarding the chronic effects of PPA or non-PPA induction in plyometric training, the results indicate that there is no significant difference in the isokinetic torque of the knee extensor muscles, but at the height of the CMJ and power jump the results indicate that the two models of Have a similar response.

As equipes brasileiras de voleibol sempre tiveram os melhores levantadores, no cenário mundial, tais como: William, Jaqueline, Maurício, Fernanda Venturini, entre outros. Esta posição é considerada como a função mais importante. Isto nos leva a acreditar na importância das características físicas, técnicas, táticas e psicológicas de um levantador. Para o estudo foram entrevistados técnicos e atletas de equipes na categoria adulta (masculinas e femininas) participantes da Superliga atual campeonato nacional. Como método utilizou-se uma entrevista sem iestruturada com estes técnicos e atletas. Para análise qualitativa foi aplicada a metodologia do DSC (Discurso do Sujeito Coletivo). Trata-se de uma técnica de pesquisa qualitativa que está sendo desenvolvida no campo da saúde desde 1997, mas que tem utilidade em todo tipo de abordagem da temática que envolva o pensamento, o sentimento, as crenças, as atitudes, os valores, as representações sociais, expressados sob a forma de discursos verbais. O procedimento da categorização das respostas (O Pensamento Coletivo como Soma Qualitativa) foi aplicado nessa fase. Consistiu em agrupar as respostas de sentido equivalente \"assim como sua força - freqüência com que uma dada Idéia Central apareceu no campo pesquisado. Das diversas questões abordadas nesta entrevista, evidenciou-se para esta pesquisa a seguinte: \"Para você, quais seriam as variáveis que um levantador deve ter para ser um atleta de alto rendimento e chegar a uma seleção nacional?\" / Brazilian volleyball teams always had the best setters worldwide, such as William, Mauricio, Jaqueline, Fernanda Venturini among others. This position is considered the most important in the team, reason why we may conclude that physical, technical, tactical and psychological characteristics are very important in a setter. The sample was composed of adult teams (male and female) coaches and athletes from \"SUPERLlGA\" - Brazilian National Championship. The methodology used was a semi structured interview. For the qualitative analysis was used the CSS (Collective Subject Speech) , a qualitative technical research that is being developed in the Health Area since 1997 and that is helpful for any study involving thinking, altitude, feeling, social representation, beliefs, expressed by verbal speech. The answers computing (collective thinking as qualitative addition) was applied at this time, and consists of joining the same sense answers as well as the incidence of the central idea occurrence in the study. Among all the questions made in this presentation one carne up: 11 What would be the most important characteristics (physical, technical, tactical and psychological) that a setter must have to acquire a high performance profile and reach a National team? \"
