Purpose: To conduct a systematic review of the evidence regarding the efficacy of exercise training in the management of cystic fibrosis (CF).Methods: Articles were found by searching PEDRO, MEDLINE, and CINAHL databases. Included articles involved exercise-related interventions for long-term adaptations (ie, not acute effects of exercise). Articles were excluded if the language was other than English or if other non-exercise interventions were used. Date of publication was not a factor for exclusion. Two independent reviewers evaluated the included articles using Sackett''s levels of evidence and select scoring criteria.Results: Twelve articles were eligible for inclusion. Interventions studied included various aspects of exercise training: anaerobic, aerobic, or resistance training. Study end-points included pulmonary function, aerobic capacity, strength, and health-related quality of life (HRQL).Conclusions: Exercise training in individuals with CF is beneficial, with aerobic and resistance training having the greatest support in the literature for improved aerobic capacity and strength, respectively. Exercise training does not appear to have an effect of improving pulmonary function, but may have a preservation effect. Strong conclusions about improvement in HQRL from exercise training cannot be made. However, greater consistency in measuring this outcome is needed in future trials. There is a paucity of evidence regarding the role of exercise training in reducing hospitalization and health care utilization, and questions raised by this review should be considered in the design of future trials.Key Words: cystic fibrosis, aerobic exercise, review 相似文献

Recent trends indicate a move away from self-contained classrooms and toward content-focused departmentalization in elementary schools. This study takes a snapshot of the existing organizational structures used in elementary schools in one district and explores administrators’ beliefs and practices regarding this phenomenon. Our findings suggest administrators base their decisions to organize grade levels on various factors, including their own experiences, contextual dynamics, and personal perceptions of outcomes for students and teachers. 相似文献

This article examines Slovak early years teachers’ concerns with conceptions of teacher professionalism. It suggests that there is a mismatch between understandings of professionalism, policy aspirations and the attitudes of teachers to their own professionalism, and that this mismatch fuels early years teachers’ sense of agency. These tensions between conceptions of professionalism, teaching practice and actual working conditions have led to a ground-up approach to self-governance within the early years teacher workforce. We analyse teachers’ discussions in an early years online forum of 12,500 members that was started and remains governed by the teachers themselves. It represents in itself a very particular attitude and response to the need to determine what it means to be a professional teacher. This analysis examines intersections of policy, quality and professionalism, and highlights considerations of power and voice, and the complexities of uncertainty and change. The article concludes with the suggestion that teacher attitudes, power and agency are impacted in unpredictable ways by the policy landscape. 相似文献

冯梦龙编纂的<新列国志>在学术界至今尚未引起应有的重视,即使面世的几篇文章都以<东周列国志>为题,这对代表一个时代的文学大师是极不公平的.实际上,<新列国志>既能佐以历史,又能在史实的框架内任意虚构,驰骋想象,塑造了一大批栩栩如生的人物形象,结构错综复杂又井然有序,语言通俗而简练流畅,取得了使原作无可比拟的艺术成就. 相似文献
