Abstract Researchers have postulated that hope may be an important factor associated with burnout. Consistent with hope theory contentions, low-hope individuals may be susceptible to burnout because they are prone to experience goal blockage, frustration, and negative affect, all of which likely increase the risk of burnout. We examined the relationship between hope and athlete burnout among 178 competitive athletes (63 females and 115 males) aged 15–20 years. Hope was significantly and negatively correlated with all three burnout subscales: emotional/physical exhaustion, a reduced sense of accomplishment, and sport devaluation. Moreover, results of a multivariate analysis of variance showed that low-hope athletes scored significantly higher than medium- and high-hope athletes on all three burnout dimensions. Finally, results revealed that agency thinking was a significant predictor of all burnout dimensions. Frustration over unmet goals and a perceived lack of agency, a characteristic of low-hope athletes, might pose a risk factor in athlete burnout, whereas being able to maintain hope appears to be associated with health and well-being. 相似文献

AbstractThis study compared the use of sand and grass training surfaces throughout an 8-week conditioning programme in well-trained female team sport athletes (n = 24). Performance testing was conducted pre- and post-training and included measures of leg strength and balance, vertical jump, agility, 20 m speed, repeat speed (8 × 20 m every 20 s), as well as running economy and maximal oxygen consumption (VO2max). Heart rate (HR), training load (rating of perceived exertion (RPE) × duration), movement patterns and perceptual measures were monitored throughout each training session. Participants completed 2 × 1 h conditioning sessions per week on sand (SAND) or grass (GRASS) surfaces, incorporating interval training, sprint and agility drills, and small-sided games. Results showed a significantly higher (P < 0.05) HR and training load in the SAND versus GRASS group throughout each week of training, plus some moderate effect sizes to suggest lower perceptual ratings of soreness and fatigue on SAND. Significantly greater (P < 0.05) improvements in VO2max were measured for SAND compared to GRASS. These results suggest that substituting sand for grass training surfaces throughout an 8-week conditioning programme can significantly increase the relative exercise intensity and training load, subsequently leading to superior improvements in aerobic fitness. 相似文献

AbstractIn solo offshore sailing races like those of the Solitaire du Figaro, sleep must be obtained in multiple short bouts to maintain competitive performance and safety. Little is known about the amount of sleep restriction experienced at sea and the effects that fatigue from sleep loss have on sailors’ performance. Therefore, we assessed sleep in sailors of yachts in the Figaro 2 Beneteau class during races and compared response times on a serial simple reaction-time test before and after races. Twelve men (professional sailors) recorded their sleep and measured their response times during one of the three single-handed races of 150, 300 and 350 nautical miles (nominally 24–50 h in duration). Total estimated sleep duration at sea indicated considerable sleep insufficiency. Response times were slower after races than before. The results suggest that professional sailors incur severe sleep loss and demonstrate marked performance impairment when competing in one- to two-day solo sailing races. Competitive performance could be improved by actively managing sleep during solo offshore sailing races. 相似文献

AbstractBased upon predictions derived from the Developmental Model of Sports Participation, we tested whether hours in domain-specific play (self-led activities) and practice (coach-led activities) during childhood (~5–12 year) in an elite group of youth soccer players from the UK (N = 144) were related to motivation. Independent analysis of three different age groups (Under 13, 15 and 17 year) did not show relations between play and practice activities during childhood and global measures of motivation. However, secondary analysis showed that when controlling for years in soccer, years in the UK Academy system were negatively related to global indices of self-determined motivation (SDI) and positively related to controlled motivation for the oldest players. Despite predictions, there was no evidence that play during childhood was positively related to more SDI. Prospective research is recommended to enable more robust conclusions about the role of early developmental practice activities, especially early specialisation in a high-performance system, on both skill and psychosocial development. 相似文献

Grounded in the conceptual framework of the Sport Commitment Model and previous empirical studies conducted in Western countries, this study was designed to (a) test and validate a Thai version of the Athlete Opinion Survey to assess components of the Sport Commitment Model in Thai youth athletes and (b) examine structural relationships among various constructs of the Sport Commitment Model as assessed by the Thai version of the Athlete Opinion Survey. Survey data were collected from 1,704 Thai youth athletes and analyzed via structural equation modeling methodologies to establish evidence for validity and measurement reliability. Results from various analyses indicated adequate support for the hypothesized factorial structure and acceptable reliability estimates of the Thai version of the Athlete Opinion Survey subscales. Moreover, modeling analyses showed empirical support for the hypothesized structural relationships underlying the Sport Commitment Model in the Thai youth athlete population. The findings from this study have implications for a better understanding of sport commitment in different cultural settings. 相似文献

Numerous events have provided evidence that the cultural values and assumptions of intercollegiate athletic departments are often incongruent with those of their host institutions. This discrepancy has even been evident in Christian institutions which seek to integrate faith into the learning experience. Using the organizational culture perspective, this study sought to determine how religion influenced the culture of one intercollegiate athletics department. The study took place at a highly selective evangelical Christian college with a nationally competitive athletic department. Data were collected through interviews with 19 campus leaders, observation of cultural events and document analysis. Analysis occurred qualitatively through a process of theorizing. The results indicate that evangelical Christianity played a significant role in the athletic department's culture by constraining its membership, influencing its pedagogy and guiding department decisions. As a result, its values and assumptions were consistent with those of the overall campus culture. The reasons underlying this cultural integration offer coaches and administrators of all institutional affiliations the possibility that the organizational culture perspective can be used to create athletic programs that are more consistent with institutional values. 相似文献

This paper identifies ‘quality’ as an internationally relevant concept to be problematised in contemporary debates about physical education (PE). Drawing on the conceptualisation of curriculum by B. Bernstein in 1977, pedagogy and assessment as three inter-related message systems of schooling, the paper presents and explores curriculum, pedagogy and assessment as three fundamental dimensions of ‘quality PE’. Discussion addresses what quality in each dimension may mean in PE, and demand in practice. Contemporary initiatives in Australia and New Zealand provide a reference point for exploring the prospective application of quality conceptualised in terms of the three inter-related dimensions. Attention is drawn to frameworks in mainstream education that may be utilised in endeavours to critically review current practices, and inform developments directed towards achieving quality in PE. It is argued that achieving quality in PE requires that quality is pursued and demonstrated within and across curriculum, pedagogy and assessment, and that meanings of quality always need to be contextualised in cultural, social and institutional terms. 相似文献

This paper represents the views of two scholars in the USA with respect to the scholar lecture presented by David Kirk at the 2012 BERA – Physical Education and Sport Pedagogy (PESP) Special Interest Group meeting. We discuss how two unique features of the American universities have an impact on both the corporate nature of our work and our scholarship. These features are described as ‘the notion of outreach scholarship’ and the ‘nature of giving.’ In addition, we discuss our different situations and how they affect our ability to do the best academic work. We can, and by consequence, give our best efforts to resist the hegemony of corporatization. 相似文献

The purposes of this study were (1) to compare the force application point (FAP) calculated by a portable force plate system and the center of pressure (COP) calculated by a pressure insole system during alpine skiing, and (2) to assess whether any statistical differences between FAP/COP characteristics were influenced by the skiing modes, skiers’ skill levels, or pitch of the slope. Seven expert and eight intermediate skiers performed 20 double turns with two different skiing techniques. Similarities between the time characteristics of both systems and repeated measures ANOVA were used for the statistical analysis. Time characteristics of both systems in the y direction (anterior–posterior) were highly comparable. The mean FAP and COP in the x direction (medial–lateral) were different in all skiing modes for the outer ski and for the inner ski for the expert skiers. The ranges of the FAP in both directions were greater than the COP in almost all conditions. 相似文献

Quality assurance in Higher Education: Fit for the new millennium or simply year 2000 compliant? 总被引:1,自引:0,他引:1
The current focus on quality assuranceprocedures emphasises compliance andaccountability. Drawing upon experience, mainlyfrom the UK, the article argues that whilstthis approach is understandable given thecircumstances of the 1990s, it has led to aninstitutional culture that is in danger ofalienating academic staff to the detriment ofthe system as a whole. If quality assurancesystems are to recognise the increasinglydiverse nature of higher education institutionsin the new millennium, compliance will need tobe balanced by a greater emphasis onencouraging innovation and self-improvement onthe part of individual members of staff. Bothquality assurance agencies and institutionsthemselves will need to adapt their policies,procedures and culture if higher educationsystems are to respond positively to thechallenges of the new millennium. 相似文献
