Construção e validação do instrumento de avaliação do desempenho técnico-tático no voleibol Construction and validation of a technical-tactical performance evaluation instrument in volleyball
O objetivo deste estudo foi construir e validar de forma preliminar um instrumento de avaliação do desempenho técnico-tático individual nas categorias de formação do basquetebol (IAD-BB). A elaboração dos indicadores baseou-se na literatura e em instrumentos de avaliação de desempenho. O processo de validação de conteúdo foi efetivado por 10 profissionais de Educação Física, especialistas da área dos esportes coletivos. A fidedignidade intra-avaliador e interavaliadores foi testada a partir da observação das ações de jogo desempenhadas por duas atletas. A análise dos dados ocorreu por meio de percentual, coeficientes de correlação (Spearman, intraclasse) e índices de concordância (Kappa). Os resultados apresentaram elevados percentuais de aceitação entre os avaliadores, tanto nos indicadores das ações quanto nas componentes técnico-táticos. Os dados de fidedignidade intra e interavaliadores evidenciaram índices de correlação e concordância considerados satisfatórios. Conclui-se que o IAD-BB revelou-se um instrumento cientificamente válido e útil como técnica de avaliação dentro dos estudos da análise do jogo.
Background: Physical activity is a positive component of human health. Its effects are associated with improvement in physical, psychological and social aspects of quality of life. Physical activity is therefore an important factor in the rehabilitation of amputees. Objective: To analyse the relationship between physical activity and quality of life for amputees in southern Brazil. Study Design: Descriptive, cross-sectional design with nonrandomized sample. Methods: A total of 40 questionnaire instruments were distributed to subjects who met the inclusion criteria, with a response rate of 55% (22 individuals, n = 15 males, n = 7 females). Outcome measurements were obtained through the International Physical Activity Questionnaire and World Health Organization Quality of Life-Bref. Results: The sample was characterized by physically active adult male prosthetic users with positive quality of life, and amputation below the right knee caused by mechanical trauma related to traffic accidents with motorcycles. Significant correlations were identified between all domains of quality of life and between level of physical activity and psychological quality of life. No correlation was identified between gender and quality of life variables or physical activity levels. Conclusions: This study showed that in very active amputees of both genders, level of physical activity is not associated with quality of life except for the psychological domain. Clinical relevanceThis paper contributes to understanding of the importance of physical activity for the quality of life of amputees, principally of active individuals with lower limb amputations. It provides evidence for the relevance of physical mobility in the process amputee rehabilitation, mainly for psychological domain of quality of life.
Resumo: O presente ensaio procurou caracterizar e discutir os contextos e situações de aprendizagem de treinadores esportivos, estabelecendo uma trajetória a partir de episódios significativos neste processo. A literatura específica indica que os treinadores têm valorizado diversas fontes de conhecimento, destacadamente as experiências de prática como atleta, a observação de seus pares, o compartilhamento de informações e a reflexão sobre sua prática. A aprendizagem profissional do treinador pode ser entendida como um processo de socialização esportiva que inicia na infância e se prolonga ao longo da vida, em que prepondera a participação do treinador em situações de aprendizagem em contexto informal.Abstract: This essay sought to characterize and discuss sport coaches' learning contexts and situations, establishing a trajectory after significant episodes in that process. Specific literature indicates that coaches have emphasized different sources of knowledge, notably practice experiences as athletes, observing their peers, sharing information, and reflecting on their practice. Coaches' professional learning can be understood as a process of sports socialization that begins in childhood and continues throughout life, where their participation focuses on learning situations in informal contexts.Resumen: Este ensayo intenta caracterizar y discutir los contextos y situaciones de aprendizaje de entrenadores deportivos, estableciendo una trayectoria a partir de episodios significativos en este proceso. La literatura específica indica que los entrenadores han valorado diversas fuentes de conocimiento, en particular las experiencias prácticas como atleta, la observación de sus pares, el intercambio de información y la reflexión sobre su práctica. El aprendizaje profesional del entrenador puede ser entendido como un proceso de socialización deportiva que empieza en la infancia y sigue durante toda la vida, en el que predomina la participación del entrenador en situaciones de aprendizaje en un contexto informal.
The purpose of this study was to explore the learning pathways of five Brazilian surf coach developers, in order to understand how they became coach developers. A case study was conducted with five surf coach developers working in the sport participation context, and linked to a legally organized Brazilian surf federation. Three main research topics guided the semi-structured interviews: participants' experiences as a surfer, as a surf coach, and as a coach developer. Data were analyzed using thematic analysis to explore the participants' perceptions of the experiences around becoming a surf coach developer. The study revealed a pattern of formative experiences for the participants, across their lives and careers. Their experiences as a surfer and as a surf coach, as well as their exposure to the surfing environment and their contact with significant others, influenced in their engagement in surfing and in the surf coach context; leading them eventually to the desire to share knowledge with others. Becoming a surf coach developer in this study corresponded to a mutual socialization process across a lifetime. This process was marked by situated socio-cultural aspects of different life phases, strongly influenced by the social relations established in immediate contexts (family) and with other specific groups (surfers, coaches, and developers).
RESUMOEste estudo analisa as fontes de autoeficácia docente de universitários em Educação Física. Foram empregados procedimentos de pesquisa qualitativa de caráter descritivo-diagnóstico. Os dados foram obtidos através de entrevista semiestruturada, baseada nos instrumentos: escala de autoeficácia docente e escala de fontes de autoeficácia docente, com 7 universitários da última fase do curso de licenciatura em Educação Física de uma universidade pública no Estado de Santa Catarina. Para a análise dos casos múltiplos, utilizou-se a técnica de análise de conteúdo, que consiste, primeiramente, na transcrição e descrição de cada caso individualmente, seguida do cruzamento e confronto das informações dos casos. Os resultados mostraram que as fontes de autoeficácia, referentes ao manejo de classe, foram: experiência de domínio (6), persuasão social (5) e vicária (4). Sobre a intencionalidade docente, as fontes mais citadas foram: experiências vicárias (7), persuasão social (7) e domínio (6). Especificamente sobre a intencionalidade docente, os universitários mencionaram uma maior diversidade de situações de autoeficácia frente ao manejo de classe. Conclui-se que a observação e a persuasão social foram as fontes de autoeficácia consensualmente valorizadas pelos universitários. Essas situações foram proporcionadas pela universidade nos estágios obrigatórios, observando e recebendo orientações dos professores da universidade e dos professores da escola. Palavras-chave: Autoeficácia. Educação Física. Universitários. ABSTRACTThe aim of this study was to analyze the sources of self-efficacy of pre-service teachers in physical education. Were employed qualitative research procedures and the data were collected through semistructured interview with 7 pre-service teachers in Physical Education from a public university. For the analysis of multiple cases was used the content analysis technique, which consists, first, in transcription and description of each case individually, then crossing and confrontation of information for all cases. The results showed that the sources of self-efficacy for the class management were the mastery experiences (6), social persuasion (5) and vicarious (4). About the teaching intentionality, the most cited sources were the vicarious experiences (7), social persuasion (7) and the mastery experiences (6). Specifically on teaching intentionality, the pre-service teachers mentioned more variety of situations of self-efficacy when compared to the management class. The observation and social persuasion were the sources of self-efficacy commonly valued by students. These situations were provided in the required stages, watching and getting supervision from teachers at the University and teachers from school. Keywords: Self-efficacy. Physical Education. Students. IntroduçãoNo contexto do ensino, as crenças podem ser definidas como atitudes, julgamentos, axiomas, opiniões, ideologias, percepções particulares de cada indivíduo 1 , ou então, como um entendimento tácito de verdades pessoais, sociais ou profis...
