Within the UK, the "Long Term Athlete Development" (LTAD) model has been proposed by a variety of national governing bodies to offer a first step to considering the approach to talent development. The model, which is primarily a physiological perspective, presents an advancement of understanding of developing athletic potential alongside biological growth. It focuses on training to optimize performance longitudinally, and considers sensitive developmental periods known as "windows of opportunity". However, it appears that there are a number of problems with this theoretical model that are not necessarily transparent to coaches. Principally, the model is only one-dimensional, there is a lack of empirical evidence upon which the model is based, and interpretations of the model are restricted because the data on which it is based rely on questionable assumptions and erroneous methodologies. Fundamentally, this is a generic model rather than an individualized plan for athletes. It is crucial that the LTAD model is seen as a "work in progress" and the challenge, particularly for paediatric exercise scientists, is to question, test, and revise the model. It is unlikely that this can be accomplished using classical experimental research methodology but this should not deter practitioners from acquiring valid and reliable evidence. 相似文献
Artificial surfaces are now an established alternative to grass (natural) surfaces in rugby union. Little is known, however, about their potential to reduce injury. This study characterises the spinal kinematics of rugby union hookers during scrummaging on third-generation synthetic (3G) and natural pitches. The spine was sectioned into five segments, with inertial sensors providing three-dimensional kinematic data sampled at 40 Hz/sensor. Twenty-two adult, male community club and university-level hookers were recruited. An equal number were analysed whilst scrummaging on natural or synthetic turf. Players scrummaging on synthetic turf demonstrated less angular velocity in the lower thoracic spine for right and left lateral bending and right rotation. The general reduction in the range of motion and velocities, extrapolated over a prolonged playing career, may mean that the synthetic turf could result in fewer degenerative injuries. It should be noted, however, that this conclusion considers only the scrummaging scenario. 相似文献
The primary purpose of this article is to provide an in-depth understanding of the manner in which surveillance technologies have become readily appropriated and utilised by elite Rugby Union coaches. It is conceded that positions adopted by populist writings commonly categorise the act of coaching as an educational activity that harnesses holistic intentions. Through reflecting upon semi-structured interviews with players located at an Aviva Premiership Rugby Union Club, we provide insight into an elite sporting institution that more accurately depicts coaching as a technocratic activity. The resultant analysis is critical in its review of surveillance mechanisms embedded in institutional practice, extending to the sports coaching setting, which explicate sinister rather than pastoral motives to enforce a disciplinary power that enhances the quantification of athletic performance. The article concludes by emphasising the impact of such practices upon establishing a sense of trust and the construction of self autonomous to the sporting domain. We argue that the emerging and steadfast acceptance of technology in the elite coaching environment is threatening to circumvent the learning potential of players by merely viewing them as functionaries. In adopting this position, we tentatively suggest that future research seeking to inform the practice of coaching and coach education should continue to pursue this critical dialogue to question whether, and to what extent, an overreliance on technology is becoming perceived as the ‘gold standard’ of professional practice amongst the coaching fraternity. 相似文献
Background: In recent years increasing attention has been given to models-based approaches to physical education as a way of promoting standards and particular types of learning through better alignment of teacher planning and delivery with pupil learning and achievement. However, little attention has been given to the specific contribution a pedagogical model for outdoor adventure education (OAE) has to make to pupils learning.
Purpose: This paper is presented in two parts. Part one is an advocacy paper and draws upon the broader discourse around models-based practice to make a case for the development of a pedagogical model for OAE. Drawing upon guidelines for models-based approaches to physical education, this paper considers the theoretical foundation, rationale, review of research findings and major theme that inform the development of a model of OAE.
Conclusions: The selected review of the research suggests that the major impact of OAE is upon the affective domain, particularly in relation to pupils developing a positive self-concept. Learning is also evident in the cognitive and physical domains, but this is secondary to learning in the affective domain. Drawing upon the analysis of the research literature, the major theme for the model is identified as ‘personal growth through adventure’ and ‘OAE’ is suggested as the name of the model. Part two of this paper builds upon these foundations to outline what a pedagogical model for OAE might look like in a secondary school in the UK. 相似文献
Relying on cultural transmission, social identity and self-categorization theories, this study uses an innovative two-part photo-pasting and survey method to investigate quantitatively and qualitatively non-fans’, fans’ and players’ assumptions about what positions black and white players should occupy in American football. Both white and black players and fans showed evidence of being cultural transmitters of racial ideologies associated with the quarterback position in American football. Overall, the respondent choices for quarterback diverged significantly from equality but not significantly from the reality of the National Football League. Players and fan and non-fan participants alike showed evidence of being cultural consumers and transmitters of racial ideologies associated with the quarterback position. Narrative reasons for player choices aligned with past literature about racial stereotypes. On most measures, the findings did not differ greatly among the institutions from which study participants were drawn, their diversity in geography, racial composition, ideology, athletic division and public–private status notwithstanding. 相似文献
We identified the perceptual–cognitive skills and player history variables that differentiate players selected or not selected into an elite youth football (i.e. soccer) programme in Australia. A sample of elite youth male football players (n?=?127) completed an adapted participation history questionnaire and video-based assessments of perceptual–cognitive skills. Following data collection, 22 of these players were offered a full-time scholarship for enrolment at an elite player residential programme. Participants selected for the scholarship programme recorded superior performance on the combined perceptual–cognitive skills tests compared to the non-selected group. There were no significant between group differences on the player history variables. Stepwise discriminant function analysis identified four predictor variables that resulted in the best categorization of selected and non-selected players (i.e. recent match-play performance, region, number of other sports participated, combined perceptual–cognitive performance). The effectiveness of the discriminant function is reflected by 93.7% of players being correctly classified, with the four variables accounting for 57.6% of the variance. Our discriminating model for selection may provide a greater understanding of the factors that influence elite youth talent selection and identification. 相似文献
ABSTRACT The role and importance of peripheral vision have been discussed across various sports. Yet, its functionality remains unclear and the terms employed in the literature to characterize the use of peripheral vision are not well defined. We present a review of 29 studies focusing on the use of peripheral vision in sports. We focus on the methodological approaches employed to study its use and identify the mechanisms that may underlie the effective use of peripheral vision in sport. We define key differences between ‘gaze anchors’ and ‘visual pivots’ and introduce the concept of a ‘foveal spot’. All three gaze behaviors, while being characterized by a consistent, dynamically adjustable gaze location, have different functionalities. A gaze anchor is a cue-optimized position used for the monitoring of peripheral cues and avoiding the negative consequences of saccades (i.e. information suppression), especially under time pressure. A visual pivot is a distance-optimized location between relevant cues which allows athletes to optimally initiate saccades to those cues, especially if the costs of eye-movements are low. A foveal spot is primarily used for information processing via the fovea. Finally, we highlight suggestions for future research to improve our understanding of the functional differences between these gaze behaviors. 相似文献
