Mothers’ voices are often silent in the sports literature, especially as elite athletes. This research used a symbolic interactionist approach and semi-structured interviews to explore the experiences of nine elite female athletes in New Zealand who were also mothers at the time of competing. The specific objectives were to explore how motherhood impacted on the identity of elite athletes, how they negotiated their multiple identities and roles, and how support systems were utilized to encourage and retain elite athletes as mothers. The women managed their multiple identities and negotiated constraints such as guilt, lack of time and limited organizational support by emphasizing how integral sport was to their sense of self. They highlighted the mutual benefits of motherhood to their sport aspirations and vice versa, by utilizing time/space management strategies, and by creating and accessing strong support networks which sometimes included organizational support. There was a move towards the integration of multiple identities and a focus on how women's choices in leisure and sport were realized for future research and theory development. Sport management practices and policies that create opportunities for mothers to achieve and maintain elite athlete status are also mentioned.  相似文献

The aim of this study was to examine the acute effects of prolonged static stretching (SS) on running economy. Ten male runners (VO2(peak) 60.1 +/- 7.3 ml x kg(-1) x min(-1)) performed 10 min of treadmill running at 70% VO2(peak) before and after SS and no stretching interventions. For the stretching intervention, each leg was stretched unilaterally for 40 s with each of eight different exercises and this was repeated three times. Respiratory gas exchange was measured throughout the running exercise with an automated gas analysis system. On a separate day, participants were tested for sit and reach range of motion, isometric strength and countermovement jump height before and after SS. The oxygen uptake, minute ventilation, energy expenditure, respiratory exchange ratio and heart rate responses to running were unaffected by the stretching intervention. This was despite a significant effect of SS on neuromuscular function (sit and reach range of motion, +2.7 +/- 0.6 cm; isometric strength, -5.6% +/- 3.4%; countermovement jump height -5.5% +/- 3.4%; all P < 0.05). The results suggest that prolonged SS does not influence running economy despite changes in neuromuscular function.  相似文献

Nostalgia and homesickness were well-known eighteenth-century ailments. Undertaking protracted travels, Grand Tourists were potential sufferers, yet these emotional afflictions are absent from the Tour's lengthy lists of hazards. Querying this and applying history of emotions approaches to the histories of the Tour, masculinity and the family, this article examines how Tourists and tutors navigated nostalgia and homesickness as emotions that sat uneasily with the Tour's wider aims of masculine formation. Such investigations offer a means of unpicking the complex, contradictory demands placed on young gentlemen during their emotional formation. Through this, it contributes to wider reconsiderations of eighteenth-century masculinity.  相似文献

Primary objective: Teacher evaluation is being revamped by policy-makers. The marginalized status of physical education has protected this subject area from reform for many decades, but in our current era of system-wide, data-based decision-making, physical education is no longer immune. Standardized and local testing, together with structured observation measures, are swiftly being mandated in the USA as required elements of teacher evaluation systems in an effort to improve school programs and student achievement. The purpose of this investigation was to document how this reform was initiated and the experiences of teachers, students and administrators, from three high school physical education programs, during initiation of this reform. Documenting how physical education programs respond to such reforms develops our understanding of top-down reform efforts and helps to identify conditions under which such reforms have the intended effect on physical education teachers and student learning in physical education.

Theoretical framework: Fullan’s three phases of school change has been used to analyze and guide school change efforts in several subject areas including physical education. The phases are initiation, implementation and institutionalization. This study is situated primarily within the first phase of school change, the initiation phase.

Methods and procedures: This study took place over a 21-month period in 3 suburban school districts in a northeast metropolitan area of the USA. Interviews with district physical education administrators, high school physical education teachers and students were conducted. Field notes of physical education classes, informal interviews and related artifacts including pre- and post-physical education assessments were collected. To ensure trustworthiness, several steps were taken including member checks, triangulation and peer review. The data were analyzed to find common themes and patterns using the constant comparative method.

Results: Several themes emerged: (1) changes in curriculum and assessment; (2) effect on administrators; (3) stakeholder apathy and (4) department collaboration.

Conclusion: Changes, although minor, did take place in the wake of this top-down teacher reform; however, additional research needs to be completed to determine whether or not these changes are meaningful or long lasting.  相似文献
