The purpose of this article is to contribute to the understanding of the emergence and change in institutional logics by analyzing the theorization (e.g., Greenwood, Suddaby, & Hinings, 2002) of a new and distinctly “different” practice in Swedish voluntary sport: drive-in sport. The article builds on data from 29 interviews with key actors involved in the organizing of drive-in sport in four municipalities. The findings show that two problems were constructed to legitimize drive-in sport: norm-breaking behavior displayed by youth during weekend nights, and organized sport's failure to live up to a sport-for-all ideal. The findings also show that it is perceived that in order for drive-in sport to be the solution to both these problems, the activities need to be arranged in a particular way. The findings are discussed in relation to recent developments in Swedish organized sport as an institutional context. Additionally, the discussion puts forth the value of the theorization concept in terms of furthering our understanding of the social-constructionist interpretive processes that underpin the broader processes of change documented in previous sport-related studies of change in institutional logics.  相似文献

It is clear that the cause of fatigue is complex, influenced by events occurring in both the periphery and the central nervous system. Work conducted over the last 20 years has focused on the role of brain serotonin and catecholamines in the development of fatigue, and the possibility that manipulation of neurotransmitter precursors may delay the onset of fatigue. While there is some evidence that branched-chain amino acid and tyrosine ingestion can influence perceived exertion and some measures of mental performance, the results of several apparently well-controlled laboratory studies have not demonstrated a positive effect on exercise capacity or performance under temperate conditions. As football is highly reliant upon the successful execution of motor skills and tactics, the possibility that amino acid ingestion may help to attenuate a loss in cognitive function during the later stages of a game would be desirable, even in the absence of no apparent benefit to physical performance. There are several reports of enhanced performance of high-intensity intermittent exercise with carbohydrate ingestion, but at present it is difficult to separate the peripheral effects from any potential impact on the central nervous system. The possibility that changes in central neurotransmission play a role in the aetiology of fatigue when exercise is performed in high ambient temperatures has recently been examined, although the significance of this in relation to the pattern of activity associated with football has yet to be determined.  相似文献

We aimed to analyse the handgrip positioning and the wedge effects on the backstroke start performance and technique. Ten swimmers completed randomly eight 15 m backstroke starts (four with hands on highest horizontal and four on vertical handgrip) performed with and without wedge. One surface and one underwater camera recorded kinematic data. Standardised mean difference (SMD) and 95% confidence intervals (CI) were used. Handgrip positioning did not affect kinematics with and without wedge use. Handgrips horizontally positioned and feet over wedge displayed greater knee angular velocity than without it (SMD = ?0.82; 95% CI: ?1.56, ?0.08). Hands vertically positioned and feet over wedge presented greater take-off angle (SMD = ?0.81; 95% CI: ?1.55, ?0.07), centre of mass (CM) vertical positioning at first water contact (SMD = ?0.97; 95% CI: ?1.87, ?0.07) and CM vertical velocity at CM immersion (SMD = 1.03; 95% CI: 0.08, 1.98) when comparing without wedge use. Swimmers extended the hip previous to the knee and ankle joints, except for the variant with hands vertically positioned without wedge (SMD = 0.75; 95% CI: ?0.03, 1.53). Swimmers should preserve biomechanical advantages achieved during flight with variant with hands vertically positioned and wedge throughout entry and underwater phase.  相似文献

Background: The latest curriculum reform in Norway is one example of an education reform with a highly emphasised assessment for learning (AfL) agenda. Acknowledging that there is a lack of empirical research on AfL in physical education (PE), and that AfL potentially can have an important role to play in development of PE pedagogy, this paper set out to examine the extent to which the emphasis on AfL from educational authorities has led to change in assessment practice in PE.

Purpose and research question: The purpose of this paper is to examine the implementation of AfL in PE at upper secondary level in Norway, and discuss possible implications. More specifically we ask ‘How do students’ and teachers' perspectives of assessment practices in PE reflect AfL key principles?'

Methods: A mixed-method design has been applied in this study. Quantitative data, collected through a questionnaire answered by 1486 students from six upper secondary schools (15–19 years), were combined and compared with qualitative data from focus groups of a total of 23 PE teachers at the same schools. Data were analysed in relation to four key principles of AfL.

Findings: For the majority of the students in the study, their reports of assessment practice in PE did not reflect the four key principles of AfL. This result was supported by the fact that their PE teachers conveyed very varied understandings and enactments of AfL. The study revealed some difference between teacher and student perspectives regarding AfL key principles, in particular regarding feedback that moves learners forward.

Conclusions: The study demonstrates limited implementation of AfL principles in PE and we conclude that the educational authorities' emphasis of AfL has not proven productive in PE. However, most of the teachers acknowledged the need to change teaching and assessment practices in PE, and all schools in the study are observed to be in an area of changing assessment. Considering the findings on different AfL key principles, this study highlights engaging student more directly in assessment processes as an important development area.  相似文献

Background: Research in sport coaching and sport pedagogy including studies published in this special issue bring to the fore the relationship between learning and culture in contexts of high-performance sport. This paper acknowledged that how learning, culture and their relationship are conceptualised is a crucial issue for researchers and professionals in high-performance sport.

Purpose and approach: This paper arises from a theoretical analysis of the research studies presented in this special issue. The analysis undertaken focused on the understanding and representation of the concepts of learning and culture and critically examined the methodological application of particular conceptualisations. The intention was to extend insight into both theoretical and methodological issues associated with understanding and researching athlete and coach learning, and high-performance sport settings.

Findings and discussion: This paper identifies tendencies for separatist and reductionist thinking about learning and culture in high-performance sport settings. A relational perspective is identified as critical to extending research and professional practice that is directed towards learning and/or culture. Researchers are urged to avoid identifying either athlete or coach learning (only) with specific events or experiences, and similarly avoid positioning culture as something that sits apart from athletes’ and coaches’ participation and learning in elite sport settings. The dual notions of ‘learning practices as cultural practice’ and ‘cultural practice as pedagogical practice’ are proposed as a basis for holistic thinking about learning and culture in high-performance sport settings. The extent to which such thinking is reflected in the various contributions to the special issue is considered. Attention is then directed to the methodological challenges that researchers face if they are to reflect a conceptualisation of learning as both embedded and embodied in cultural practices. Challenging and extending the underlying vision of learning that researchers, coaches and athletes have is revealed as a critical consideration in regard to research design, data collection and ways in which participants are variously positioned, represented and ‘involved’ in research. Embodied perspectives are identified as particularly worthy of greater attention in contemporary research that seeks to extend understanding of athlete and/or coaches’ learning and lived experiences within and amidst elite sporting cultures. Recent scholarship focusing on the body and lived experience is identified as providing theoretical and methodological insights that can extend future research and practice.

Conclusions: Foregrounding a relational perspective is fundamental to extending the understanding of learning and culture in high-performance sport. Future research also needs to clearly embrace the methodological challenges presented by new conceptualisations.  相似文献

This paper interrogates the media articulation of football/soccer to New Zealand national consciousness during the 2010 FIFA World Cup. 541 articles from national and regional newspapers and Internet news sites were gathered and analysed using a critically discursive approach. I argue that the press re-framed football within the national sporting imagination in the context of a narcissistic nationalism. Coverage was underpinned by several interlocking themes. First, falsely positing football as ethnically inclusive by emphasizing Māori players’ presence in the national team. Second, the entrenchment of archetypes and caricatures of both others and the national self. This included the evocation of a mythic New Zealand masculinity, with specific individuals lionized as key embodiments of the fictive national character. Third, the caricaturing of other nationalities is also used to bolster the national self – in particular the Italians and Australians. Such framings resonate with long-standing themes in the selective construction of a settler-informed New Zealand nationalism. Coverage, however, ignores the complexity of how individuals are flexibly and ambiguously articulated to the nation, particularly in the context of the global football labour market.  相似文献

Media provides a material site for girls' identity formation and presents conflicting images of femininity, which challenge young women's self-expression and physicality development. The ‘problem’ with girls' physicality has not been resolved, but rather complicated by discourses of new femininities in sport, fitness and health promoted by the new economies. Girls' conscious and unconscious consumption of messages of new powerful femininities might be troubling for some girls, especially ‘Other’ girls and/or girls ‘at risk,’ whose physicality collides with the emerging image of the new girls. Therefore, in this paper, I contend that an investment in the third-wave feminist agenda is still necessary to engage scholars, educators and girls in critical conversations about media, genders, the body and identity. To this end, first I discuss the feminist reappraisal of Foucault's analysis of the body as an emancipatory socio-educational and political project for (en)gendering research on the feminine ‘docile body’ in society. Second, I highlight emerging contemporary monocultural discourses of the ‘Alpha Girl’ and the ‘Future Girl,’ powerful sporty, fit and healthy femininities that contradict discourses of the traditional feminine docile body, and I analyze the ways these new images subsume race, class, religion and disability. Finally, I conclude this article by advocating the adoption of critical media pedagogies as a potential strategy for schooling girls' hybrid bodies.  相似文献

Business historians have led the way in research into company paternalism and the origins and development of welfare provision. Their work has focused on large-scale enterprises and has generally located welfare (‘sports and social’) within the broader framework of company culture. Whilst much of welfare provision is related to sport and recreation, sports historians have perhaps neglected this area in recent years. This paper will begin to redress this imbalance by examining the origins and development of work-based sport and recreational provision at four major employers – Robinson & Sons (textile & packaging manufacturers, Chesterfield), Raleigh (cycle manufacturers, Nottingham), Lyons, (food processors and caterers based in West London), and the Bank of England. Among business historians the prevailing view is that such provision was a management strategy designed to encourage loyalty to the firm. It will be argued here that it was more of a ‘bottom-up’ process with workers initiating, organising and sustaining clubs and societies, albeit with a good deal of financial and logistical support from their employers.  相似文献

Abstract

The aim of the current study was (1) to investigate whether the number of accelerations is a more precise estimate of performance decline in soccer compared to distances with high-speed running (HSR) and (2) to compare changes in the number of accelerations and HSR distances across playing positions in order to examine whether the match profiles of the physical measures are consistent or demonstrate high interposition variability. The dataset includes domestic home games (N?=?34) over three full seasons (2012–2014) for a team in the Norwegian Elite League. The change in the number of accelerations throughout the match demonstrates a more clear pattern compared to the distance covered by HSR. In numbers of accelerations, a systematic and linear decrease can be observed throughout the match, with 34% less accelerations from the first to the last 5-minute period of the game (6.7 vs. 4.4 accelerations). This pattern of results captures the change in the number of accelerations across all positions. HSR distance had more variability during the match. All five positions investigated displayed a similar trend in accelerations and HSR profiles after the peak periods in each half. In contrast to the absolute number of accelerations, there were major positional differences in the mean HSR distance during the match. Our data suggest a more visible performance decline in the number of accelerations from the start to the end of the game, than the decline in the distance covered by HSR distance.  相似文献

Anticipation is an important performance factor in karate kumite. A new approach analysing anticipation in realistic combat situations by motion capturing with a high temporal resolution is presented. The advantage of this approach is that both karate athletes interacting sports specific can be recorded synchronously; thus, the presented method has the potential to analyse visual information pickup due to coordination pattern of interaction between real athletes. The aim is to demonstrate the usability of the current method for anticipation research and to investigate if the distance between two athletes and their attacking technique play a role in the reaction of the defending athlete. Furthermore, relevant cues lying within each attacking technique and little individual differences are shown. Four male karate athletes took part in this study. Logistic regression indicated that both factors (distance × attacking technique) play a significant role in reaction. However, a correlation between these factors shows that only the attacking technique is a good predictor for reaction. Results show that the attacking technique jabbing punch (jap. Kizami-Zuki) was easier to anticipate than the attacking techniques reverse punch (jap. Gyaku-Zuki) and the round kick (jap. Mawashi-Geri).  相似文献

An increased interest in health, diet, and physical activity exist among young people, in this study termed ‘fitness hype’. Viewing the body and health as commodities can be understood as part of a healthism discourse. In this study, we explored how Swedish high school students perceive and negotiate the trend regarding exercise, diet and body ideals. Semi-structured interviews were conducted with ten high school students, aged 16–18 years, from various educational programs and with varying levels of physical activity. Using qualitative content analysis, we developd one overarching theme navigating life satisfaction in the face of an ‘unhealthy fitness hype’. Four additional, interrelated categories showed how the young people negotiated this developing trend through: (1) the quest for social recognition and value, (2) social media sets the standards, (3) the paradox of strong and skinny as the new standard, and (4) the need for new safety nets. Our results highlight the young people’s perceptions of an excessive and influential focus on health and exercise in contemporary society. They described a fitness hype as exorbitant and unhealthy ideals of body and exercise, and understood this as problematic. Social media was seen as contributing to this hype as a powerful arena for ‘the quest for social recognition and value’. While not all the young people felt negatively affected by the fitness hype, they perceived its influence on their lives. Further, body and fitness ideals were gendered. Teenage girls faced the paradox of shaping themselves as ‘strong and skinny’. Social ties were recognized as an important safety net, particularly classmates, sports mates, and coaches. Knowledge of these problems from the perspective of young people is crucially needed among health professionals and educators. Further research should explore additional support strategies, and young people’s experiences of fitness hype among additional youth groups.  相似文献

Background: This paper is part two of a discussion about a new pedagogical model for adventure in the curriculum. It builds upon part one, the advocacy paper, which considered important theoretical foundations, historical influences and research outcomes of outdoor adventure education (OAE) in the UK.

Purpose: This paper outlines how a model for OAE might be implemented in practice in schools in the UK. Four non-negotiable features of a pedagogical model for OAE are identified as essential for pupils to gain maximum benefit from their outdoor adventure experiences. Consideration is also given to other essential features of models-based approaches to physical education that teachers need to consider to underpin the model's authenticity, including pupils’ readiness for learning, teacher expertise and knowledge, and assessment and future model validation.

Conclusions: Four non-negotiable features of a model for OAE are identified as being mainly outdoors, experiential learning, challenge by choice and managed risk. Key concerns arising from the implementation of these non-negotiable features are considered. These include encouraging pupils to take more responsibility for their own learning, developing closer links between school OAE and local opportunities, supporting teachers in making judgements about pupils managing their own risk, developing teachers’ expertise in reviewing and developing assessment tools that measure pupils’ affective learning.  相似文献

Abstract

On April 1, 2018, the new standards of compliance to the code of the World Anti-Doping Agency (WADA) came into force. The new standards impact all sports. An important amendment has been made to an article of the existing code ‘Additional Roles and Responsibility of the Parties’. Now, all international federations and the unions in agreement with WADA are obliged to reject applications for holding all sporting events from countries that do not comply with the WADA code. By then, Russian elite sport remained in isolation because the Russian Anti-Doping Agency (RUSADA) had no license from WADA until a compromise agreement allowed Russia back into international sports in September 2018. The probability of obtaining permanent return to international sport was extremely low. In order to obtain the license, Russian sport authorities were asked to agree with the reports of Professor McLaren and to admit the existence of doping support in the country at the state level, which seemed improbable. In Russia, although the new standards of the World Anti-Doping Agency code have not caused special concerns it directly impact Russian elite sport. Unless certain conditions were met by 2019, there was a high probability that Russia would not be able to attend large international competitions in the near future, including the 2020 Tokyo Olympics. The situation dictates the choice of the new strategy of development for Russian sport and new model for the fight against doping, which can be not dependent on WADA. To date, there have been no real checks on WADA’s authority other than occasional decisions in the Court of Arbitration for Sport. Academics who are critical of WADA’s functions often find themselves marginalized when the purported global doping “crisis” should bring “all hands on deck” to provide a humanistic and scientific approach that is best for athletes past, present and future. The functions of WADA in investigating, charging and punishing athletes do not contribute to sustainable development of sport and the sports industry around the world, and create unipolar environment of influence on sports development. Therefore, in this article, we describe some alternative forms and new order of regulation of the anti-doping relations in sport.  相似文献

Abstract

The purpose of this study was to determine the validity and reliability of a new method for measuring three-dimensional (3D) putting stroke kinematics using the TOMI® device. A putting robot and a high-speed camera were used to simultaneously collect data for the validity evaluation. The TOMI® device, when used in conjunction with standard 3D coordinate data processing techniques, was found to be a valid and reliable method for measuring face angle, stroke path, putter speed, and impact spot at the moment of ball contact. The validity of the TOMI® measurement system was quantified using the 95% limits of agreement method for each aforementioned variable. The practical significance of each validity score was assessed by incorporating the maximum estimated measurement error into the stroke of the putting robot for 10 consecutive putts. All putts were executed from a distance of 4 m on a straight and flat synthetic putting surface. Since all putts were holed successfully, the measurement error for each variable was deemed to be negligible for the purposes of measuring putting stroke kinematics. The influence of key kinematic errors, at impact, on the outcome of a putt was also determined.  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

This study sought to compare the kinetics and kinematics data in a group of habitual shod runners when running in traditional running shoes and newly designed minimalist shoes with lug platform. This novel footwear design claims to simulate barefoot running and reduce energy loss during impact. We compared footstrike angle (FSA), vertical average (VALR) and instantaneous (VILR) loading rates, energy loss and initial vertical stiffness between two shoe conditions. Runners demonstrated a decreased FSA while running in minimalist shoes with lug platform than traditional shoes (= 0.003; Cohen’s = 0.918). However, we did not observe a landing pattern transition. VALR and VILR between two footwear conditions showed no significant difference (= 0.191–0.258; Cohen’s = 0.304–0.460). Initial vertical stiffness (= 0.032; Cohen’s = 0.671) and energy loss (= 0.044; Cohen’s = 0.578) were greater when running in minimalist shoes with lug platform. The results show that minimalist shoes with lug platform reduce the FSA but may not lead to a landing pattern switch or lower vertical loading rates. Interestingly, the new shoe design leads to a greater energy loss than traditional running shoes, which could be explained by a higher initial vertical stiffness.  相似文献
