Abstract Exercise and sport scientists are increasingly faced with the need to demonstrate that their work is based on a sound evidence base and has an impact on professional practice and policy. This evidence is often derived from systematic reviews of rigorously designed studies such as randomized controlled trials. This paper addresses some of the limitations of the exclusive reliance on such trials and highlights the importance of addressing issues of effectiveness and practical concerns when synthesizing research evidence. The “Better Practices” model is then described in the context of a current project examining exercise and smoking cessation. This model provides one framework for integrating critical reviews of empirical evidence with contextual and practical considerations relevant to organizations interested in the translation of the synthesis into practice. Strengths and weaknesses of the model are discussed regarding its potential consideration and application by exercise and sport scientists. 相似文献

Open-boat sailing boomed in Sydney, Australia, during the 1890s, as a number of new sailing clubs emerged in the city's working waterfront suburbs. Open boats have since been remembered as ‘typically Australian’, radically opposed to the forms and ceremonies of the yachting establishment, and even as sharing the characteristics of the bushman, an archetype of Australian national identity. This article traces the rise of open-boat sailing as a working-class spectator sport and the associated image of an ‘open boat legend’. It argues that open-boat sailing remained a Sydney legend in the 1890s. However, links to working traditions and place have made it possible for popular histories of sailing and yachting to present the open boats and sailors of the period with identifiably Australian characteristics. 相似文献

The aim of this paper was to critically review existing literature relating to, and critically analyse current conceptualisations of, ‘coaching philosophy’. The review reveals a bewildering approach to definitions, terms and frameworks that have limited explanation and reveal a lack of conceptual clarity. It is argued that rather than provide clarification and understanding the existing literature conflates coaching rhetoric and ideology with coaching philosophy and serves to reproduce existing coaching discourse rather than explain coaching practice. The paper problematises the unquestioned assumptions currently underpinning ‘coaching philosophy’; namely the overemphasis of coaches' agency and reflexivity, the downplaying of the significance of social structure on coaches' dispositions and the acceptance that coaching practice is an entirely conscious activity. The paper argues for an alternative philosophy of coaching that uses philosophic thinking to help coaches question existing ideology, and critically evaluate the assumptions and beliefs underpinning their practice. 相似文献

Abstract We explored sport performers’ cognitive appraisals of organisational stressors. The relevant demands and transactional alternatives that athletes experience in relation to the situational properties were identified. Thirteen national standard swimmers completed semi-structured, interval-contingent daily diaries for a 28-day period. A combination of inductive and deductive content analysis was used to organise and analyse the diary entries with a focus on the following areas: organisational stressors, their underlying situational properties, and the swimmers’ transactional alternatives. One hundred and thirty-one of the organisational stressors were appraised as threat, 41 as challenge, and 83 as harm/loss. Support was found for the majority of Lazarus and Folkman's (1984) situational properties with the only exception being temporal uncertainty. Imminence was associated with the greatest number of threat appraisals (47), novelty was associated with the greatest number of challenge appraisals (17), and duration was associated with the greatest number of harm/loss appraisals (22). It is concluded that appraisal plays a pivotal role in sport performers’ experiences of their organisational environment. Swimmers’ transactional alternatives are influenced by the situational properties of the stressors encountered. 相似文献

In this article, I will identify two key normative principles at the core of Robert L. Simon’s mutualist theory of sport, namely, the respect-for-the-opponent principle and the idea that sport is a practice aimed at pursuing excellence. The former is a Kantian principle grounded in human beings’ rationality, and the latter is an Aristotelian principle related to the development of excellences as a means to human flourishing. After having presented and analyzed both principles, I will critically evaluate Simon’s attempt to combine them within his mutualist approach. To conclude, I will highlight the challenges that mutualism should face to complete such a combination more successfully.Abbreviation: Categorical imperative (CI) 相似文献

The objectives of this study were to describe the volleyball spiking actions used by players in top‐level competition, and also to examine the interrelationships between upper limb, lower limb and whole body kinematic variables, and post‐impact ball speed in the spiking technique. Two Photosonics Biomechanics 500 cine‐cameras operating at a nominal frame rate of 100 Hz were used to film the spiking actions of 10 male senior international volleyball players at the XVI Universiade (1991 World Student Games). Three‐dimensional object space co‐ordinates of digitized image co‐ordinates were obtained using a DLT algorithm and an array of calibration points in the filmed volume. Relationships between lower limb angular kinematics at take‐off, centre of mass vertical velocity at take‐off and centre of mass vertical displacement (jump height) were examined. Relationships between angular kinematics of the hitting arm and post‐impact ball speed were also determined. The mean (± S.E.) centre of mass vertical velocity at take‐off was 3.59 ± 0.05 m s‐1 and the mean height jumped was 0.62 ± 0.02 m. As expected, a significant correlation was found between the square of the centre of mass vertical velocity at take‐off and jump height (r = 0.78; P <0.01). No significant correlations were found between lower limb angular kinematics and centre of mass vertical velocity at take‐off or jump height. The mean post‐impact ball speed was 27.0 ± 0.9 m s‐1, and this was significantly correlated to maximum right humerus angular velocity (r=0.75; P< 0.01). Trunk rotation angular kinematics and right elbow angular velocity did not correlate significantly with post‐impact ball speed. It was also noted that the majority of players filmed did not fit into any of the spiking categories identified in earlier studies. 相似文献

Modelling itself on the organizational structure and the physical fitness culture of Catholic scouting, the xaveri movement in Rwanda developed within a climate which was highly susceptible to the development of deep racial and political divisions. Between 1954 and 1964, this Catholic youth organization was influential in the gestation of a Christian democratic culture which was one of the essential elements of the ideology behind the ‘Hutu revolution’. Covering the colonial to the postcolonial period and from the angle of the rise of the xaveri movement, this paper shows how the ‘Hutu revolution’ was a consequence of a liberation struggle from an imagined oppressor. This is in reference to colonial privileges attributed (until the end of the 1940s) to the Tutsi minority. However, and still from the perspective of the organization explored here, it seems that the model of the ‘civilised Tutsi’ targeted by the revolutionary Hutu movement was the essential referent of the more subconscious invention by republican leaders. 相似文献

In this study, we examined aspects of the 4 2 100 m relay that are amenable to mathematical analysis. We looked at factors that affect the time required to complete the relay, focusing on the performance of elite male athletes. Factors over which the individual athletes, and the team coach, can exercise some control are: the starting positions of the runners on legs 2, 3 and 4, the positions at which baton exchanges occur, the free distances at the baton exchanges and the running order of the athletes. The lane draw is shown to have an important influence on the relay time, although it is outside the control of the team coach. Teams drawn in the outside lanes benefit from the inverse relation between bend radius of curvature and running speed. For teams composed of athletes with different times over 100 m, we show that the fastest relay times are achieved with the fastest athlete taking the first leg, with the slowest two runners allocated to the final two legs. 相似文献

It is widely assumed that there is an eccentric hamstring muscle fibre action during the swing phase of high-speed running. However, animal and modelling studies in humans show that the increasing distance between musculotendinous attachment points during forward swing is primarily due to passive lengthening associated with the take-up of muscle slack. Later in the swing phase, the contractile element (CE) maintains a near isometric action while the series elastic (tendinous) element first stretches as the knee extends, and then recoils causing the swing leg to forcefully retract prior to ground contact. Although modelling studies showed some active lengthening of the contractile (muscular) element during the mid-swing phase of high-speed running, we argue that the increasing distance between the attachment points should not be interpreted as an eccentric action of the CE due to the effects of muscle slack. Therefore, there may actually be no significant eccentric, but rather predominantly an isometric action of the hamstrings CE during the swing phase of high-speed running when the attachment points of the hamstrings are moving apart. Based on this, we propose that isometric rather than eccentric exercises are a more specific way of conditioning the hamstrings for high-speed running. 相似文献

This paper addresses issues raised in Paul Ward's essay ‘Last man picked’, focusing on methodological and discipline-refining questions to call for a more open dialogue between sports historians and others in the discipline. The argument includes a call on the wider discipline to both recognise the need for and participation in sub-discipline specific debates. 相似文献

Abstract An investigation was undertaken to determine possible age and race difference between Black and Caucasian girls ages 6, 7, and 8 years. Ninety female subjects were administered 28 test items measuring speed, muscular power, agility, flexibility, balance, muscular endurance, and cardiorespiratory endurance. Few significant differences were observed between adjacent ages but 8-year-old females were significantly superior to the 6-year-old subjects on most motor performance variables utilized. For race comparisons, no significant differences were noted for measures of flexibility, muscular endurance, cardiorespiratory endurance, speed, balance, or muscular power. The Black subjects were significantly superior on two measures of agility while the Caucasian subjects performed significantly better on the time-limit shuttle run and grip strength. 相似文献

AbstractThe history, milestones and (sluggish) progress towards gender equality within the interconnected movements of sport, international development and human rights are reflective of the broader feminist struggle. In this paper, we shall explore how key stakeholders, such as the United Nations Educational, Scientific and Cultural Organization (UNESCO), the (former) United Nations Office on Sport for Development and Peace (UNOSDP), the International Olympic Committee (IOC) and the International Working Group (IWG) on Women and Sport together with other women and sport organisations have been working to promote gender equality within and beyond sport. Despite decades of parallel or synchronized effort, critics contend that progress is slow and uneven, leaving generations of girls and women marginalized. In this article, we explain the progression towards a renewed initiative to create a UNESCO Global Observatory for Women, Sport, Physical Education and Physical Activity and discuss how the observatory should serve as a nexus of these collective movements by bringing advocacy, research and action together in one platform. 相似文献

There is currently a distinct dearth of research into how sports students' career aspirations are formed during their post-compulsory education. This article, based on an ethnographic study of sport students in tertiary education, draws on data collected from two first-year cohorts (n = 34) on two different courses at a further education college in England. The study draws on ethnographic observations, and semi-structured group interviews, to examine in-depth the contrasting occupational perspectives emergent within these two groups of mainly working-class students, and how specific cultural practices affect students' career aspirations. Utilising a Bourdieusian framework, the paper analyses the internalised, often latent cultural practices that impact upon these students' diverse career aspirations. The hitherto under-researched dimension of inter-habitus interaction and also the application of doxa are outlined. The article reveals how the two student cohorts are situated within a complex field of relations, where struggles for legitimisation, academic accomplishment and numerous forms of lucrative capital become habituated. The study offers salient Bourdieusian-inspired insights into the career aspirations of these predominantly working-class students and the ways in which certain educational practices contribute to the production and reproduction of class inequalities. 相似文献

The Civil War between the Kuomintang (KMT) and Communist Party that ended in 1949 caused a confrontation between the ‘Free China’ in Taiwan claimed by the Republic of China, the KMT that retreated to Taiwan, and the ‘New China’ established by the People’s Republic of China. The sport policies of the ‘Two Chinas’ were based on the respective political positions, which were affected greatly by the Cold War. Taiwan, ruled by the KMT affiliating with the camp of the capitalists led by the USA, was the revival base to connect with Chinese in several East and Southeast Asian countries and to connect with other Asian anti-Communist countries. Political and military policies contributed to Taiwan women’s basketball development during the Cold War in East Asia and the first national team named Liangyou thus emerged. The Liangyou’s life symbolized the beginning and the phased ending of women’s basketball development in Taiwan, and skilful players of noble character practised loyal diplomatic missions and publicized the strong body-mind heroine image of Free China. Their healthy and cheerful character along with a passion for basketball provided new ideas of women’s roles in post-war Taiwan. Trips for overseas competitions let players experience the outside world. 相似文献

The purposes of this study were: (a) to analyze the factors determining the quality of relationships between a novice physical education (PE) teacher and his students’ families and (b) understand the implications of these relationships for his professional identity. The data stemmed from detailed teacher’s diaries written by the participant throughout his first five years of teaching. The data analysis followed several rounds of cyclical inductive-deductive processes in order to identify and classify the patterns related to the aforementioned purposes. The results, presented in two sections, show two distinct sets of factors, which, respectively, had very different implications for the development of the teacher’s professional identity. On the one hand, in the first three years of teaching, there appeared 11 specific ‘struggle factors’ (6 socio-cultural and structural factors and 5 family prejudices toward PE) that threatened the teacher’s initial pedagogical passion and lead to a great deal of hesitation and discouragement on his part; on the other hand, in the fourth and fifth years, due to the teacher’s ongoing commitment and (self-)reflective practice, there emerged eight ‘success factors’ (one from the families and seven from the teacher) that transformed his previous discouragement into hope and self-confidence. Besides the detailed analysis of all these factors and their implications, some additional recommendations for PE teacher education programs and further research are provided. 相似文献
