Abstract-The present study investigated the correlation between Transition I with victory in volleyball matches. The 2002 South-American Youth Men's Championship was recorded and the Transition I was analyzed and classified as negative, null or positive. Results of the efficiency in Transition I was calculated using t test for independent samples and compared to the efficiency between teams during each set and matches. Spearman correlation assessed the relationship between efficiency in each set and results of the matches with the final ranking in the championship. The results showed that the winning teams exhibited higher efficiency in Transition I, as well as a positive relationship of higher efficiency in Transition I with all of their results. The higher efficiency in Transition I is related to victory in volleyball matches. Keywords: sport, volleyball, transitions, skills, efficiencyResumo-"Eficiência de Transição I e vitória em partidas de vôlei." O presente estudo investigou a correlação entre Transição I com a vitória em jogos de voleibol. O Campeonato Masculino Sul-Americano da Juventude 2002 foi gravado para analisar e classificar Transição I como negativa, nula ou positiva. Os resultados da eficiência na Transição I foram calculados por meio do teste t para amostras independentes para comparação com a eficiência entre as equipes durante cada set das partidas. A correlação de Spearman avaliou a relação entre a eficiência em cada set e os resultados das partidas com a classificação final do campeonato. Os resultados mostraram que as equipes vencedoras exibiram maior eficiência na Transição I, bem como uma relação positiva de maior eficiência na Transição I com todos os seus resultados. A maior eficiência na Transição I está relacionada à vitória em partidas de vôlei.

La mayor eficiencia en la Transición I se relaciona con la victoria en las partidas de voleibol.

Purpose. In this study, we investigated the effects of the distribution of practice (distributed vs. massed) on the learning of a coincident timing task by young and older adults. Methods. Sixteen young adults and sixteen older adults were subdivided into distributed and massed practice groups. The participants completed a coincident timing task that consisted in touching five sensors in sequence under a time constraint in two learning phases: acquisition and transfer. Results. There were no performance differences between the groups in the acquisition phase. However, older adults in the massed practice group featured the poorest performance in the transfer test. No differences were found among the other groups. Conclusions. Older adults are more receptive to distribution practice as massed practice was found to lead to poorer learning. comparisons of learning effectiveness between young and older adults are dependent on the adopted intra-session intervals. In addition, the conflicting results on distribution of practice may be related to subject-task interactions.

The aim of this study was to investigate the short and long-term effects of the bandwidth KR in learning of the absolute and relative dimensions of a motor skill. Twenty-two undergraduate students divided into two groups: G15 who received KR when the relative error exceeded 15%; and G0, with KR after every trial. The study consisted of an acquisition phase, and the volunteers practiced 100 trials with a target time of 850 ms and relative of 22.2%, 44.4% and 33.3% between the first and second, second and third, third and fourth keys, respectively. This phase, KR related to relative time (relative error) was provided according to the group. KR of total target time was available to both groups after all trials. Three retention tests with ten trials were conducted 10 minutes, 24 hours and one week after the acquisition phase. The results showed that G15 had a smaller relative error than G0. This study allows concluding that bandwidth KR in relation relative time error showed its effects in the consistency of relative time. These effects persisted even after seven days after the acquisition phase in a delayed retention test.

Trotes acadêmicos são tradicionalmente constituídos por ações de constrangimento,humilhação e dominação dos veteranos nas universidades. Para mudar essapercepção negativa e objetivando a inserção e a integração dos alunos ingressantes,surge o Projeto de Extensão Trote Solidário no IFC – Campus São Bento do Sul.Discentes calouros dos cursos de Engenharia de Controle e Automação eEngenharia de Computação, com demais colegas e servidores, realizam ações decunho social na região além de outras atividades criativas. O projeto também buscaestimular e sustentar a prática do voluntariado como uma rotina dentro do IFC, pormeio de parcerias com ONG’s.
