Mental Preparation Strategies of Olympic Archers During Competition: an exploratory investigation     

Claudio Robazza  Laura Bortoli 《High Ability Studies》1998,9(2):219-235

Extensive interviews were conducted with all eight members of the 1996 Italian Olympic archery team regarding psychological factors associated with excellence and mental preparation strategies adopted during competition. Hierarchical inductive analysis revealed that positive expectations, concentration, facilitating emotions, body awareness and technical preparation were the mental aspects described by archers necessary for effective performance. Furthermore, the archers outlined a variety of mental preparation strategies including (a) autonomic control (emotion control, somatic control, internal dialogue, and focus on shooting), (b) imagery (visualization, self‐talk), (c) task‐focused concentration (body and action control, thought control) and (d) reaction to mistake (focus on correct execution, mistake disregard, shooting analysis). The idiosyncratic nature of the athlete's competition strategies highlights the need of gaining information about the particular demands of the sport and the mental procedures spontaneously developed by the performer, to provide suitable counselling or psychological intervention.  相似文献   

The geometric curvature of the spine during the sirshasana,the yoga’s headstand     

Mário Hebling Campos  Nayane Martins Giraldi  Paulo Gentil  Claudio Andre Barbosa de Lira  Carlos A. Vieira  Marcelo Costa de Paula 《Journal of sports sciences》2017,35(12):1134-1141

This study analysed the behaviour of the geometric curvature of the spine during sirshasana. The position of dorsal retroreflective markers was computed via stereophotogrammetric analysis in six males and five females (29.4 ± 8.8 years, 63.0 ± 11.4 kg, 1.66 ± 0.08 m [average ± standard deviation]). The spinal points were projected onto the sagittal and frontal planes of the trunk, a polynomial was fitted to the data and the two-dimensional geometric curvature was quantified. The inferior lumbar lordosis decreased compared to the orthostatic position and gait, which may favour the posterior protrusion of the lumbar spinal nucleus pulposus in people with posterior herniation. The lateral deviation at the middle of the thoracic spine increases during sirshasana, which may reflect increased difficulties for postural control and spinal loads. It could be useful for promoting positive spinal structural and functional chronic adaptations for healthy participants, if the yoga programme is carefully planned and the spinal alignment is carefully monitored during a headstand. However, it may aggravate some spinal diseases, especially scoliosis.  相似文献   

Predicting athletes’ functional and dysfunctional emotions: The role of the motivational climate and motivation regulations     

Montse C. Ruiz  Saara Haapanen  Asko Tolvanen  Claudio Robazza  Joan L. Duda 《Journal of sports sciences》2017,35(16):1598-1606

This study examined the relationships between perceptions of the motivational climate, motivation regulations, and the intensity and functionality levels of athletes’ pleasant and unpleasant emotional states. Specifically, we examined the hypothesised mediational role of motivation regulations in the climate–emotion relationship. We also tested a sequence in which emotions were assumed to be predicted by the motivational climate dimensions and then served as antecedents to variability in motivation regulations. Participants (N = 494) completed a multi-section questionnaire assessing targeted variables. Structural equation modelling (SEM) revealed that a perceived task-involving climate was a positive predictor of autonomous motivation and of the impact of functional anger, and a negative predictor of the intensity of anxiety and dysfunctional anger. Autonomous motivation was a partial mediator of perceptions of a task-involving climate and the impact of functional anger. An ego-involving climate was a positive predictor of controlled motivation, and of the intensity and impact of functional anger and the intensity of dysfunctional anger. Controlled motivation partially mediated the relationship between an ego-involving climate and the intensity of dysfunctional anger. Good fit to the data also emerged for the motivational climate, emotional states, and motivation regulations sequence. Findings provide support for the consideration of hedonic tone and functionality distinctions in the assessment of athletes’ emotional states.  相似文献

The social-cognitive mechanisms regulating adolescents' use of doping substances     

Lucidi F  Zelli A  Mallia L  Grano C  Russo PM  Violani C 《Journal of sports sciences》2008,26(5):447-456

In this study, we assessed the longitudinal effects of social-cognitive mechanisms on the self-reported use of doping substances and supplements among Italian high school students. In total, 1232 students completed questionnaires measuring various psychological factors hypothesized to influence students' intention to use substances. Three months later, 762 of the students completed the same questionnaires a second time and also reported their use of substances during the time between assessments. Overall, the percentages of students using doping substances (2.1%) or supplements (14.4%) were consistent with values reported in the literature. Analysis of the data showed that adolescents' intention to use doping substances increased with stronger attitudes about doping, stronger beliefs that significant others would approve of their use, a stronger conviction that doping use can be justified, and a lowered capacity to resist situational pressure or personal desires. In turn, stronger intentions and moral disengagement contributed to a greater use of doping substances during the previous 3 months. Doping use was also correlated significantly to supplementation. In conclusion, our results provide novel information about some of the psychological processes possibly regulating adolescents' use of doping substances and supplements. The results also highlight possible areas for future study and intervention, focusing on the prevention of adolescents' substance use.  相似文献   

Measuring systematic long-term trajectories of school effectiveness improvement     

Juan Pablo Valenzuela  Cristián Bellei  Claudio Allende 《School Effectiveness & School Improvement》2016,27(4):473-491

The objective of this study was to identify trajectories of school improvement experienced by Chilean elementary schools over the last decade. Using econometric analysis and controlling for potential confounding factors, we created an index of school performance combining outcome indicators focused on different school dimensions, and estimated the 2002/2010 evolution of school improvement for all Chilean schools with available data. Broadly, we estimated an average increase in the school performance of about 0.19 SD; nevertheless, while 41% of the schools increased their educational performance by at least 0.1 SD, 25% of the schools decreased it during the same period; we also found that improving school effectiveness was more probable among schools with lower student socioeconomic status (SES). Finally, we found that the observed school improvement trajectories tended to be non-linear; thus, we estimated that only 13.4% of the schools improved their performance in a systematic way during the entire decade.  相似文献

The impact of social media on informal learning in museums     

Angelina Russo  Jerry Watkins  Susan Groundwater‐Smith 《Educational Media International》2013,50(2):153-166

This paper posits that social networking can take a central role in learning in informal environments such as museums, libraries and galleries. It argues that social media offers young people agency previously unavailable in informal learning environments in order to explore complex responses to and participation with cultural content. The paper will consider transformations in digital literacy and the processes by which young learners can connect with knowledge in informal learning environments to become active cultural participants.

Die Wirkung sozialer Medien auf informelle Bildung in Museen

Dieses Papier postuliert, dass soziale Vernetzung eine zentrale Rolle im Lernen in informellen Umgebungen wie Museen, Bibliotheken und Galerien annehmen kann. Es behauptet, dass soziale Medien jungen Leuten als Agentur in informellen Lernumgebungen dienen können, die zuvor nicht verfügbar sind, um komplexe Antworten zu erkunden und Beteiligung mit kulturellem Inhalt zu erkennen. Die Autoren betrachten Transformationen in digitalen Fähigkeiten und den Prozessen, durch die junge Anfänger sich mit Wissen in anderen informellen Bildungsumgebungen verbinden können, um aktive kulturelle Teilnehmer zu werden.

L’impact des medias “sociaux” sur l’apprentissage informel dans les musées

Le présent article affirme que la mise en réseau humain peut jouer un rôle central pour l’apprentissage dans des environnements informels comme les musées,les bibliothèques et les galeries. Il avance que les medias “sociaux” offrent aux jeunes des moyens qui n’existaient pas auparavant dans les environnemetns d’apprentissage informels pour permettre d’explorer des réactions complexes et d’interagir avec le contexte culturel. Les auteurs examinent les mutations de la compétence numérique et les processus par lesquels les jeunes apprenants peuvent se brancher sur la connaissance dans des environnements d’apprentissage informels pour devenir des acteurs culturels dynamiques.

El impacto de los medios colectivos sobre el aprendizaje informal en los museos

Esta artículo postula que la creación de redes humanas puede desempeñar un papel central para el aprendizaje en entornos informales como los museos, las bibliotecas y las galerías. Apunta que los medios sociales ofrecen a los jovenes capacidades que antes no estaban asequibles dentro de los entornos de aprendizaje informal para explorar las respuestas complejas y interagir con el contexto cultural. Los autores consideran las transformaciones en el alfabetismo digital y los procesos a través de los cuales los jovenes alumnos pueden conectarse con los conocimientos dentro de esos entornos informales de aprendizaje para convertirse en actores culturales dinámicos.  相似文献
