Revista Brasileira de Cineantropometria e Desempenho Humano , 2007,
Abstract: A capacidade do atleta em detectar as rea es de ativa o que lhe s o mais significativas e descobrir o estado ideal de execu o, é uma das competências psicológicas mais determinantes para uma atua o efi caz no esporte de alto rendimento. O presente estudo foi realizado com uma equipe campe olímpica no v lei de praia masculino e visou analisar as técnicas ou estratégias psicológicas utilizadas pelos atletas para regular os seus níveis de ativa o diante das situa es competitivas durante as partidas. Os dados foram coletados durante seis etapas do circuito mundial que antecederam os Jogos Olímpicos de Atenas, por meio de um segmento específi co do instrumento feedback de execu o, destinado a registrar o nível de ativa o percebido em cada partida e as técnicas ou estratégias psicológicas utilizadas para a regula o da sua ativa o em diferentes situa es do jogo. O registro dessas informa es foi feito pelos próprios atletas (auto-preenchimento) 30 min. após o término de cada jogo. Os resultados encontrados, a partir da técnica de análise de conteúdo, sugerem que os campe es olímpicos do v lei de praia mantiveram um ótimo nível de ativa o na maioria dos jogos disputados, independentemente das situa es vivenciadas durante as partidas. As técnicas psicológicas mais empregadas para regular seus níveis de ativa o foram técnicas cognitivas, que se baseiam na modifi ca o ou ajuste dos principais determinantes do comportamento (pensamento, percep o, memória, linguagem) e compreenderam o autoinforme, a focaliza o da aten o e a imagina o. ABSTRACT The ability of athletes to detect the activation reactions that are most signifi cant to them and to discover the ideal performance state is one of the psychological competencies that is most determinant of an effective outcome in high performance sport. The present study was carried out with an Olympic Champion male beach volleyball team and aimed to analyze techniques or psychological strategies used by the athletes to regulate their activation levels during competitive situations during the game. Data were collected during six phases of the world beach volleyball tournament that preceded the Olympic Games in Athens, using a specifi c segment of a feedback execution instrument, which is designed to register perceived the activation level in each game and the techniques or psychological strategies used to regulate activation in different game situations. Data were provided by the athletes (self-report) 30 min after the end of each game. The results suggest that the Olympic Beach Volleyball Champions mainta

Abstract: the aim of this study was to evaluate changes in motor imagery ability in response to a specific dart throwing training. twelve subjects (17-22 years) with no previous experience in dart throwing or imagery agreed to participate. changes in imagery ability were assessed using the sports imagery questionnaire before (pretreatment) and after (post-treatment) an imagery training program consisting of 10 sessions. retention (ret) was assessed 2 weeks after training. the program included mental exercises designed to develop vivid images, to control one's own images, and to increase perception about performance. comparison of the imagery training conditions (training alone, training accompanied, observing a colleague, and during assessment) showed no differences between the pretreatment, post-treatment and ret evaluations. although imagery ability did not respond to training, significant differences between imagery domains (visual, auditory, kinesthetic, and animic) were found (p<0.05), except between the visual and animic domains (p=0.58). these differences might be related to subject's domain preference subject during the imagery process and to the nature of the task in which the skill technique used seems to be a relevant aspect.
