Contexto esportivo e as restrições comportamentais: reflexões a luz da psicologia bioecológica

To deal with restrictions takes in them to a boarding that has been studied as perspective theoretician to understand as the practitioners acquire standards of coordination in the chosen sports (ARAUJO, 2005). It is basic for the training that if has a knowledge concerning the restrictions more significant than they act on the human performance of the athletes, because this will make possible one adequate recital in the work proposal of the team staff. The question of the theory application, in the world of the sport, is a tool has very desired and pursued, however, nor always if they apply the theoretical knowledge in experimental research that promotes enough and important alterations, that can favor the real additions to Sport Sciences. This study it is an attempt to collaborate in this intention, in way to locate and to modify beginning usual routines between experts and of the sports, in special to the considered situation sports, as the Volleyball (IVOILOV, 2001). This objective is not fixed only in the relative questions to the teach-learning processes, nor so little to the sportive training, but it advances, also, for the instructions given for the coaches to commanded its, at moments any of the sportive trajectory of these; it innovates when searching to exemplify, directly, in a modality of international domain but with few systematic analyses on the human performances in question.

Efeitos da música no desempenho de uma atividade física

A música está sendo muito utilizada nos dias de hoje. Suas funções variam de diversas formas. No meio esportivo não é diferente. Seja para pedalar, caminhar, correr, fazer ginástica, ou musculação, podemos perceber sua crescente utilização. Muitos estudos mostram os diversos efeitos que a música pode causar no organismo humano. Do mesmo modo, muitas pesquisas evidenciam as melhoras que a atividade física pode proporcionar ao ser. O presente trabalho tem como principal objetivo verificar a influência da música na atividade física através de músicas preferidas e não preferidas pelos atletas. Sua justificativa se dá pelo benefício em diversas áreas da educação física, como auxílio aos profissionais da área para o planejamento, desenvolvimento e adaptação às suas aulas, complementação de pesquisas maiores e mais amplas e o auxílio aos praticantes para uma melhor performance e um melhor resultado durante a prática de exercícios físicos. A hipótese inicial deste trabalho foi de que a audição da música preferida influenciaria positivamente a prática da atividade física. Para a realização do mesmo, três estudos foram realizados com 10 atletas, todos do sexo masculino, com idade entre 18 e 23 anos, alunos do curso de Educação Física, selecionados aleatoriamente. Antes de iniciar a parte prática, os participantes responderam a um questionário para que posteriormente fosse realizado o estudo proposto. Em cada estudo os atletas correram duas voltas ao redor do Campus da UNESP – Rio Claro, num total de quatro quilômetros. No primeiro estudo o percurso seria sem a audição de música. No segundo, com audição de música preferida pelo atleta e no terceiro com audição de musica não preferida pelo mesmo. Em todos os estudos o tempo de percurso foi anotado. Os dados coletados na pesquisa foram cruzados... (Resumo completo, clicar acesso eletrônico abaixo)

Influência da torcida sobre o desempenho de atletas de voleibol

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)

Avaliação das variáveis técnicas no contexto esportivo

Assessment is a theme explored in various areas of human performance, particularly for the analysis of an athlete performance and/or all team members in game situation. Assessment requires different tests and models to quantify strengthens and weaknesses of an athlete and of the team. With that in hand, it is possible to develop an intervention program, with consequent improvement of techniques and tactics play systems. The present study aimed to identify, in the literature, the athlete's performance ratings and of the team in game situation for team sport. Based on the literature review, we propose a set of variables to include in an instrument for basketball performance assessment. The methodology for the present study involved a collection of materials, including scientific articles, books, websites, academic papers. The present research comprises the concepts and definitions related to: team sport; the relevance of game analysis and its development; the advantages and disadvantages of different assessment techniques, particularly in team sports; and lastly, the instruments used for assessment in the context of team sport athletes. From the literature review we propose a set of variables that may be useful to consider in an assessment instrument for basketball performance

Heterogeneidade do desempenho de alunos da Unicamp, do ingresso à conclusão

The aim of this work is to propose a methodology to evaluate the performance of students at Unicamp [São Paulo State University at Campinas] from admission to graduation. The sample consists of all students enrolled in Unicamp from 1997 to 2000, and the population corresponds to the universe of students throughout the existence of the university. The available database was gathered from socio-cultural questionnaires applied by the University Commission on College Entrance Examination at the time of enrollment for the examination (vestibular) and from academic information provided by the Unicamp Academic Studies Board. A methodology is proposed based on the relative gain variable suggested by Dachs and Maia (2006). This new methodology is based on the diversity measures proposed by Rao (1982) and on the use of U-statistics. Homogeneity tests have been proposed to assess whether there is a difference in performance among students from different groups.

Desempenho analítico de laboratórios prestadores de serviço na determinação de metais em águas

Analytical laboratories are expected to produce reliable results. Decision makers are guided in their actions (financial, legal and environmental) using analytical data provided by numerous laboratories. This work aimed to evaluate the analytical performance of Brazilian laboratories on producing trustworthy results. Nineteen laboratories, accredited and non-accredited ones, were contracted to analyze a USGS (United States Geological Survey) certified water sample for 17 chemical elements (mostly metals) without knowing the origin of the sample. Considering all the results produced, only 35% of them were valid. Three laboratories present satisfactory performances, whereas the majority showed a very poor overall performance. The outcomes of this work show the need for a more effective analytical quality program to Brazilian laboratories.

Desempenho físico-mecânico de minipainéis de terra crua tratada com aditivos químicos

The aim of this research was to study the effect of chemical additives (lime and Portland cement) associated with sodium silicate on soil in order to obtain compressed soil bricks. Mini panels were constructed with such bricks being their physical and mechanical characteristics determined in laboratory conditions and their behavior evaluated through the association of destructive and non-destructive methods. For this purpose a sandy soil and a finely divided one were added to Portland cement and lime in the dosage of 6% and 10% taken in dry weight basis in relation to the dry soil. The sodium silicate dosage of 4% was also taken in dry weight basis in relation to the dry soil-cement or to the dry soil-lime. The compressed soil bricks were cured in a humidity chamber for 7; 28; 56 and 91 days. The bricks were laid on the fourteenth day to form prismatic mini panels each one with four layers of bricks. After 28; 56 and 91 days the mini panels were submitted to both; ultrasonic and compressive tests to determine its elastic properties (dynamic modulus) and the compressive resistance. The best results in terms of compressive strength, water absorption capacity or dynamic elastic modulus, were reached by the sandy soil added to 10% of Portland cement or lime associated with sodium silicate.

Efeito de 13 semanas de treinamento físico militar sobre a composição corporal e o desempenho físico dos alunos da escola preparatória de cadetes do exército

INTRODUCTION: Armies from all over the world acknowledge the importance of good physical fitness for the performance of military duties. The Military Exercise Training (MET) attempts to provide assistance to this search for better physical fitness and performance. OBJECTIVE: To verifying the effect on the body composition and physical performance of the students at ESPCEX (Military School for Preparation of Army Cadets) after 13 weeks of MET. METHODS: The sample was formed by 287 male students from the ESPCEX, whose average age was 18.33 ±1.26. Such students accomplished a boarding school routine, having defined schedules, meals and activities from which they were only released during the weekends. The MET was accomplished five days a week and it comprised both aerobic and resistance training. Measurement of body mass, height, skinfold (triceps, abdominal and suprailiac) was accomplished during pre and post training periods, and the following tests were performed: 12-minutes-run, oblique sit up, arm push up and pull up. Fat percentage, fat-free body mass and fat body mass were calculated using the anthropometric data based on the Guedes 3 skinfold protocol. RESULTS: Significant reduction in fat body mass, fat percentage and in triceptal and abdominal skinfold, as well as increase in suprailiac skinfold and fat-free body mass was observed when anthropometric and body composition data were compared, during the initial and the final periods of training. Significant improvement also occurred in all prformed physical tests, in which better performance was achieved. CONCLUSION: The acquired data suggest that performance of MET 5 days a week brought significantly improved body composition as well as physical performance
