Although much research has examined the relationship between exercise and affect, few studies have considered the effects of exercise bouts of different durations and few researchers have questioned the longer term effects that might be associated with acute exercise. The aim of this study was to compare the effects of the standard health recommended exercise duration of 30?min with a shorter (15?min) bout of exercise upon individuals' affect scores both during and after exercise. Twenty-three (mean age 22.4 years) physically active participants engaged in two counterbalanced cycle ergometer exercise conditions for 15?min (short bout) and 30?min (moderate bout). The participants completed the Subjective Exercise Experience Scale before, during, 5?min, 30 mins, 1?h and 2?h after both exercise conditions. A series of 2 × 6 within-participant repeated-measures analyses of variance for positive well-being (P?<0.01), psychological distress (P?<0.01) and fatigue (P?<0.01) scores revealed significant time main effects, with improved scores over time. No significant differences were noted between the 15-min and 30-min exercise bouts. These results indicate that positive affective responses are experienced by exercisers after relatively short bouts of acute exercise and these effects can still be evident some time later. 相似文献

Establishing a requirement for, justifying public spending on, and evaluating the effectiveness of anti-doping policies all accentuate the need for reliable estimates of doping prevalence in sport. To date, despite considerable effort and much empirical research, this critical information is still not available. Methodological concerns that make doping epidemiology research difficult have been noted, and to some degree addressed in relation to under-reporting bias. In this paper, we use a simple game model to outline a potential responding behaviour among self-reporting athletes on the use of doping that could potentially invalidate any prevalence estimation arising from self-reports. We show a paradoxical situation in which a potential strategic behaviour inevitably leads to a game where the ‘lying’ is a dominant strategy for both doping users and non-users. A slightly more advanced look at the situation might possibly alter this seemingly absurd conclusion, however not in a direction offering any easy solutions for empirical doping research. Although we acknowledge that the proportions of respondents engaging in false telling are likely to vary across samples and differ between doping users and clean athletes, our simple model effectively draws attention to a neglected side of evasive responding in surveys. The response bias that potentially could lead to under- and over-reporting should be considered when self-reported prevalence rates are used to inform anti-doping prevention and intervention policies. Survey methodologies that are able to account for potential distortions would make a considerable contribution to doping research. 相似文献

This essay explores the evolution of modern sporting goods retailing through the development of Gamage's (A.W. Gamage Holborn Ltd.) before the First World War. The essay examines how Gamage's exploited new models of fashionable consumerism to create a unique retail environment that directly targeted young male consumers enjoying modern forms of sporting and recreational activities. By the end of the nineteenth century, the so-called ‘People's Popular Emporium’ purported to be the ‘world's largest sport and athletic outfitter’. The essay considers Gamage's rise to prominence in a crucial period in the development of commodity culture. It examines the changing cultural form of shops and shopping in relation to the desires of a burgeoning mass market that sought to express and visibly display its economic, sporting, and social status. 相似文献

The purpose of this investigation was twofold: (a) to explore and describe the relationships between different facets of motivation, involvement, and commitment to running, and (b) to test whether recreational coached runners differ from non-coached runners in their motivation, involvement, and commitment to running. Drawing on the psychological continuum model (PCM), a model was proposed to test relationships among motives, attitudinal and behavioral involvement, and commitment to running as a leisure activity. Results showed that two (enjoyment and health) out of five motives were significant indicators of attitudinal involvement. Attitudinal involvement was a significant predictor of behavioral involvement, which in turn was a significant predictor of commitment. Coached runners differed from non-coached runners in all tested variables. The structural relationships among the variables varied based on the tested group. Implications for theory and practice are presented. 相似文献

AbstractBulgaria was one of the leading sport nations of the second half of the twentieth century; however, the Bulgarian national anthem has not been played at Olympic Games since 2008. In the current article, historical records on planning are compared to the results of athletes to determine the factors behind the remarkable rise and decline of Bulgarian sport during the last six decades. Historical geographical information systems (GISs) are used to analyze the spatial distribution of Olympic medals in each of the successfully developed sports. The data reveal that often the central Bulgarian planners failed to achieve the goals set in the ambitious programme of the totalitarian communist state. In spite of the efforts for diversification, Bulgaria’s success came from only seven sports mainly: less than any other of the leading sport nations during the 1970s and the 1980s. At the same time, the victories of Bulgarian athletes had little impact on the sport activity of the common Bulgarian. 相似文献

This article presents extensive new material in ‘the origins of football debate’ by using the British Library's digitisation project of nineteenth-century newspapers. In so doing, it responds to claims from Graham Curry and Eric Dunning that previous works of the ‘revisionist historians’ John Goulstone, Adrian Harvey and Peter Swain are misleading and have led to hasty conclusions. It evidences a football culture beyond the domain of the public schools and highlights the shift in the locus of games from urban areas to paddocks and fields complying with the Highways and Police Acts. This compliance reduced the number of prosecutions covered in newspaper reports of the day but other games, in which misdemeanours took place, are recorded, suggesting that a broad football culture did still exist in this period. The article rejects Curry and Dunning's thesis surrounding a mid-century ‘civilising spurt’ in sport in favour of explanations surrounding the structural changes taking place in the nineteenth century, including increasing industrialisation, urbanisation, population growth, and migrationary movements. It also emphasises the emergence of a horizontally stratified class-based society and an attack on football games from an emerging social and industrial elite who were looking after their property and commercial interests. 相似文献

The article uses an episode from the television series ‘The Sopranos’ to illustrate how embodied experiences of sporting practices such as high-school football involve both conscious and unconscious dynamics. It outlines how cultural practices such as masculinist sport are psychically incorporated into the body through the process of identification. The article uses Freud's concept of identification to explain how fantasy and representation are involved in the formation of embodied subjectivity. Contemporary queer theories about identification provide insights into how psychic dynamics both reinforce and undermine the illusory cultural promise of heteronormative whiteness offered by high-school sport and physical education. 相似文献

The Coach–Athlete Relationship Questionnaire was developed to effectively measure affective, cognitive, and behavioral aspects, represented by the interpersonal constructs of closeness, commitment, and complementarity, of the quality of the relationship within the context of sport coaching. The current study sought to determine the internal reliability and factorial validity of the long (the 29-item Long Version Coach–Athlete Relationship Questionnaire) and short (11-item Coach–Athlete Relationship Questionnaire and 13-item Greek Coach–Athlete Relationship Questionnaire) versions of the Coach–Athlete Relationship Questionnaire with a sample of 800 Chinese coaches and athletes. Results supported the internal reliability across all Coach–Athlete Relationship Questionnaire versions examined, while confirmatory factor analyses (CFA) only supported the factorial validity of the three-factor first-order model of the 11-item Coach–Athlete Relationship Questionnaire. The results are discussed in terms of their implications for theory, research, and practice. 相似文献

The aim of this study was to assess the effect of the hand’s acceleration on the propulsive forces and the relative contribution of the drag and lift on their resultant force in the separate phases of the front crawl underwater arm stroke. Ten female swimmers swam one trial of all-out 25-m front crawl. The underwater motion of each swimmer’s right hand was recorded using four camcorders and four periscope systems. Anatomical landmarks were digitised, and the propulsive forces generated by the swimmer’s hand were estimated from the kinematic data in conjunction with hydrodynamic coefficients. When the hand’s acceleration was taken into account, the magnitude of the propulsive forces was greater, with the exception of the mean drag force during the final part of the underwater arm stroke. The mean drag force was greater than the mean lift force in the middle part, while the mean lift force was greater than the mean drag force in the final part of the underwater arm stroke. Thus, swimmers should accelerate their hands from the beginning of their backward motion, press the water with large pitch angles during the middle part and sweep with small pitch angles during the final part of their underwater arm stroke. 相似文献

AbstractExamining the use of sport by totalitarian regimes during the interbellum period reveals that politicians saw the potential of sport not only for patriotic expression and international exhibition but also as a means to exert control over youth. Francoism participated in such uses of sport, imitating German and Italian organizations’ development of a youth sport structure. The Franco regime emphasized sport in universities to the extent that it made physical education a required subject to obtain a degree. This study’s primary objective is to reconstruct the doctrinal genesis of Francoist university sport, tracing it to the years before the Spanish Civil War, specifically noting the international influences that sustained it and the draft regulations that gave it legal standing despite resistance from both university youth and from sport. To this end, documentary sources are analyzed, including archival material, printed sources (legal decrees written during the period examined in this study and historical accounts of the subject), publications of Falange and related organizations, and speeches and proclamations from Falange and the Sindicato Español Universitario (SEU). 相似文献

This paper explores the awareness of the young German and Norwegian participants in the Youth Olympic Games (YOG) of the additional educational mission of this new event, implemented by the International Olympic Committee. Among the questions considered are whether the nature of the event contradicts its claimed intention to focus on both competition and education. Data were collected through a set of interviews with young German and Norwegian athletes at the Singapore YOG in the summer of 2010 and the Innsbruck YOG in the winter of 2012. The findings revealed (1) a focus on elite sport by athletes and their coaches, while the educational aims were considered secondary; (2) that it was problematic for the young participants to focus on education in a high-performance event. The overall conclusion was that the YOG have had only limited success in achieving the educational ambitions of the Olympic Movement. 相似文献

This study examined the effects of different work?–?rest durations during 40?min intermittent treadmill exercise and subsequent running performance. Eight males (mean?±?s: age 24.3?±?2.0 years, body mass 79.4?±?7.0?kg, height 1.77?±?0.05?m) undertook intermittent exercise involving repeated sprints at 120% of the speed at which maximal oxygen uptake (v-[Vdot]O2max) was attained with passive recovery between each one. The work?–?rest ratio was constant at 1:1.5 with trials involving short (6:9?s), medium (12:18?s) or long (24:36?s) work?–?rest durations. Each trial was followed by a performance run to volitional exhaustion at 150% v-[Vdot]O2max. After 40?min, mean exercise intensity was greater during the long (68.4?±?9.3%) than the short work?–?rest trial (54.9?±?8.1% [Vdot]O2max; P?<?0.05). Blood lactate concentration at 10?min was higher in the long and medium than in the short work?–?rest trial (6.1?±?0.8, 5.2?±?0.9, 4.5?±?1.3?mmol?·?l?1, respectively; P?<?0.05). The respiratory exchange ratio was consistently higher during the long than during the medium and short work?–?rest trials (P <?0.05). Plasma glucose concentration was higher in the long and medium than in the short work?–?rest trial after 40?min of exercise (5.6?±?0.1, 6.6?±?0.2 and 5.3?±?0.5?mmol?·?l?1, respectively; P?<?0.05). No differences were observed between trials for performance time (72.7?±?14.9, 63.2?±?13.2, 57.6?±?13.5?s for the short, medium and long work?–?rest trial, respectively; P = 0.17), although a relationship between performance time and 40?min plasma glucose was observed (P?<?0.05). The results show that 40?min of intermittent exercise involving long and medium work?–?rest durations elicits greater physiological strain and carbohydrate utilization than the same amount of intermittent exercise undertaken with a short work?–?rest duration. 相似文献

The centenary of the death of Albert Craig is an appropriate moment for a retrospect of his contribution to the popular sporting poetry of the time. Occasional brief personal reminiscences or short appreciations of Craig have surfaced after his death. This article attempts to remedy the previous lack of a full-length study of a remarkable figure who entertained huge numbers of sporting spectators with his compositions and his conversation. Craig's progress through an unrivalled career is followed chronologically and thematically. It is supported by contemporary reports and by collecting together some 500 surviving examples of his work culled from sources previously unconsidered. 相似文献

This historical study will examine the rise of a hegemonic group of sports officials in Israel during the period between 1948 and 1996. The formation of this group is a unique phenomenon of the Israeli sport society. The main argument of the study is that officials of rival sport centres, ‘Hapoel’ and ‘Maccabi’, founded a joint elite group as a side effect of the ‘fifty-fifty’ agreement, signed in 1951. The agreement stated that the Israeli Sport Association, the National Olympic Committee and the Israeli Football Association would be mutually led by officials of both organizations. The members of this elite group, who enjoyed access to economic resources and other benefits, adopted a hedonistic lifestyle, in contrast to the social ethos of Israeli society in the first and second decades of the State. Three events dismantled the group in the middle of the 1990s. The first one was the establishment of the Elite Sport Department in 1984. The second was the establishment of independent Federations by Yadin Machnes. The third was the Maliniak Commission Report. These three events led to the collapse of the Israeli Sport Association in 1996 and to the fall of the Israeli hegemonic group. 相似文献

This study tested a computer‐aided coaching analysis instrument (CAI) as part of an intervention strategy designed to modify verbal coaching behaviour. Four coaches were observed and analysed over 12 practice sessions. Coaches A, B and C received intervention feedback through CAI data, where selected behaviours were highlighted for discussion, and videotape images were used to illustrate discussion points. Coach D was provided with videotapes of his own performance and told to formulate and implement any of his own recommendations. The CAI data are primarily quantitative, so target values were created for the different dimensions of verbal behaviour. This benefited the coaches in interpreting their effectiveness and provided a reference to evaluate the magnitude of change. Written journals and audiotape recordings were also used to promote insight into the complexity of verbal behaviour and the ‘human factors’ (e.g. relationship with players, attitude to researcher) that affect behaviour modification. Instructional effectiveness was assessed by time‐series analysis. There was evidence from each behaviour dimension that change can occur and be maintained as a result of exposure to the CAI intervention strategy. However, this is clearly contingent upon the coach understanding what is asked of him or her, and remains focused and committed to changing these particular behaviours. The analysis of Coach D's behavioural change suggests there are limitations to the sensitivity of discretionary viewing, as only two dimensions of behaviour were identified for, and resulted in, positive change. The results of this study provide support for Locke's (1984) contention that behaviour modification can occur by using data as direct feedback, as reinforcement and as information in the form of recommendations. However, the study also illuminates several factors that can negate the modification and maintenance of verbal coaching behaviour. 相似文献

This article seeks to add to the growing volume of evidence of a broad, tenacious and visible footballing culture throughout nineteenth-century Britain. It is argued that football persisted among the general population in a variety of forms, none of which required the assistance or involvement of the public schools or public schoolboys to ensure its survival as some historians had previously believed. Indeed, the sheer number of games, evidenced in a variety of forms and a variety of settings, suggests beyond reasonable doubt that most forms of football being played across the country were not formal matches but small-sided games played on church, works' or schools' outings, at rural fetes, galas and celebrations, or as street or casual football, the latter taking place on meadows, fields and greens. Contrary to orthodox historians, these games did survive through mid-century. Importantly, these were predominantly small-sided games and are the ones which are closest to Association football as it was codified in 1863 and hence of most interest to the debate on origins. Common sense then dictates that football can be seen as a cultural continuity, especially as far as the traditions of male youth are concerned, across the nineteenth century. 相似文献

The aim of this study was to investigate the acute effects of prior exercise (warm‐up and stretching) on the electromyographic and force output of mechanically elicited triceps surae reflexes. Fifty male subjects performed eight reflex experiments under each of three successive conditions in one session: (1) no prior exercise, (2) after static stretching of the passive triceps surae (3 min) and (3) after a 10‐min warm‐up run on a treadmill. Tendon tap reflex force was elicited in the triceps surae of the right leg by means of a standardized reflex hammer and measured in a custom‐built fixture. Electromyographic (EMG) signals were recorded with surface electrodes over the medial head of the gastrocnemius (G) and the soleus (S). Low coefficients of variation within subjects contrasted with high between‐subject variations, indicating highly individual reflex characteristics. After stretching, reductions in the peak force (‐5%; P < 0.05), the force rise rate (‐8%; P < 0.01), the half relaxation rate (‐5%; N.S.), the EMG amplitudes (G, ‐16%; S, ‐17%; P < 0.01) and integrals (G, ‐15%; S, ‐18%; P < 0.01), and an increase in EMG latencies (G, +3%; S, +1%; P < 0.01), were found compared with the values obtained without prior exercise. After running, the peak force reached the values obtained without prior exercise (‐2%; N.S.), the force rise rate and half relaxation rate increased by 8 and 12%, respectively (P < 0.01), and the impulse (force‐time integral; ‐12%), EMG amplitudes (G, ‐20%; S, ‐23%; P < 0.01), integrals (G, ‐18%; S, ‐23%; P < 0.01) and latencies (G, ‐1%; S, ‐2%; P < 0.01) decreased significantly. The changes in the force characteristics observed after the stretching treatment indicate improved muscle compliance that might reduce the risk of injury. On the other hand, the changes after the additional warm‐up run had a more pronounced influence with regard to improved force development and a decreased EMG activity, which can be viewed as a performance‐enhancing effect. 相似文献
