Gucký, Lukáš January 2016 (has links)
Title: Analysis of the influence of beach volleyball training to young indoor volleyball players. Aim: The aim of this diploma thesis is to find out expert opinions of coaches who operate in Czech volleyball, about influence of beach volleyball training to young indoor volleyball players. Furthermore, this thesis should bring information about if coaches would recommend to using beach volleyball training for young indoor volleyball players development. Secondary aim of this thesis is to find out opinions of coaches operating in USA universities about the same topic. Method: I've used method of questioning by nonstandardized questionnaire with closed and opened questions to fulfill the objective. The data obtained from the questionnaire was analyzed by the sum of the number of probands and their answers. The results were processed by conventional statistical methods, expressed in words, graphs and tabulated. Results: The results of this study have illustrated opinions of coaches, about the issue of influence of beach volleyball training to young indoor volleyball players. Keywords: Volleyball Beach Volleyball Infuence of beach volleyball training Development of young players

Do ponto de vista técnico-tático, a capacidade de executar passes adequadamente pode contribuir para o êxito competitivo. No entanto, poucos estudos investigaram os efeitos de diferentes sessões de treino nesta habilidade técnica específica. Com isso, o objetivo geral do trabalho foi investigar o efeito agudo de sessões de treino gerais e específicas sobre a habilidade técnica de passe em jovens jogadores de futebol. Para isso, duas etapas foram desenvolvidas, sendo uma observacional, orrespondendo ao período de recrutamento, caracterização das sessões de treino e reprodutibilidade do protocolo de avaliação, e outra experimental, na qual foram aplicados os testes, pré e pós-intervenções, compostas por sessões de treinos gerais e específicas. Os resultados apontam que o teste é reprodutível em superfície de campo gramado, mais específica à prática do futebol. Além disso, poucas são as diferenças em variáveis de análise de tempo emovimento, fisiológicas e de percepção de esforço entre jovens da categoria sub-15 e sub-17 nas sessões propostas neste estudo. Ademais, na análise pré e pós-treino de sprints repetidos, com mudança de direção a cada 10 metros, houve diminuição do rendimento dos atletas da sub-17, o que não foi verificado na sessão com trocas a cada 20 metros, jogos em espaços reduzidos de 2 vs. 2 e 4 vs. 4. Já na comparação entre os tipos de treinos de sprints repetidos (10m vs. 20m) e jogos em espaços reduzidos (4 vs. 8 jogadores), as trocas a cada 10 metros e o 2 vs. 2 provocaram aumento no tempo de penalidades, respectivamente. Dessa forma, há indicação de que treinos com menor demanda psicofísica, tanto gerais, quanto específicos, possam induzir maior queda de rendimento na habilidade de executar sequência aleatória de passes em jovens futebolistas. Esses achados auxiliam no planejamento e aplicação de treinos dentro da modalidade, considerando que os conteúdos possam ser distribuídos de forma a otimizar o aprimoramento do desempenho dos atletas. / Football success is multifaceted and the training process in the modality makes use of general and pecific exercises. From the technical-tactical point of view, the ability to execute passes properly can contribute to competitive success. However, few studies have investigated the effects of different training sessions on this specific technical skill. Thus, the overall objective of the study was to investigate the acute effect of eneral and specific training sessions on the technical pass ability of young soccer players. To that end, two stages were developed, one observational, corresponding to the recruitment period, characterization of the training and reproducibility sessions of the evaluation protocol, and another one, in which the tests were applied, pre- and post-intervention, Composed of general and specific training sessions. The results indicate that the test is reproducible on grassy field surface, more specific to soccer practice. In addition, there are few differences in time-varying physiological, physiological, and effort-perception variables among sub-15 and sub-17 youth in the sessions proposed in this study. In addition, in the pre and post-training analysis of repeated sprints, with a change of direction every 10 meters, there was a decrease in the performance of the sub-17 athletes, which was not verified in the session with changes every 20 meters, games in spaces Reduced from 2 vs. 2 and 4 vs. 4. In the comparison between types of repetitive sprints (10m vs. 20m) and games in tight spaces (4 vs. 8 players), changes every 10 meters and 2 vs. 2 caused an increase in the time of penalties, respectively. In this way, there is indication of That training with lower psychophysical demands, both general and specific, may induce a greater drop in performance in the ability to execute random sequence of passes in young soccer players. These findings help in the planning and application of training in the modality, considering that the contents can be distributed in order to optimize the performance improvement of the athletes.
