Home IV Antibiotic Therapy and Exercise Capacity in Children with CF: A Case Series     

Narelle S. Cox  Karen O. McKay  Jennifer M. Follett  Jennifer A. Alison 《Cardiopulmonary Physical Therapy Journal》2011,22(1):16-19

Purpose: This case series describes the effect of home intravenous (IV) antibiotic therapy on spirometry and exercise capacity in a group of children with cystic fibrosis (CF). Methods: Outcomes from 10 children with CF who were prescribed a 14-day course of home IV antibiotics for a respiratory exacerbation are reported. All children performed spirometry and a modified shuttle test (MST) before and after 14-days of home IV therapy. Results: After 14 days, FEV₁ increased by mean (± SE) 12 ± 4 % (p < 0.05) but mean MST did not improve compared to baseline. All children improved or maintained spirometry values with treatment, however, only 5 improved MST distance. Conclusion: After 14 days of home IV antibiotic therapy, a significant improvement in spirometry, but not exercise capacity, was seen in this small series of children with CF. The lack of improvement in exercise capacity for all children following home IV antibiotic therapy suggests factors other than spirometry determine exercise capacity. Identifying and investigating the factors that influence exercise capacity during home IV antibiotic therapy requires further investigation.Key Words: cystic fibrosis, home IV therapy, FEV₁, Modified Shuttle Test  相似文献   

Use of deterministic models in sports and exercise biomechanics research     

Chow JW  Knudson DV 《Sports biomechanics / International Society of Biomechanics in Sports》2011,10(3):219-233

A deterministic model is a modeling paradigm that determines the relationships between a movement outcome measure and the biomechanical factors that produce such a measure. This review provides an overview of the use of deterministic models in biomechanics research, a historical summary of this research, and an analysis of the advantages and disadvantages of using deterministic models. The deterministic model approach has been utilized in technique analysis over the last three decades, especially in swimming, athletics field events, and gymnastics. In addition to their applications in sports and exercise biomechanics, deterministic models have been applied successfully in research on selected motor skills. The advantage of the deterministic model approach is that it helps to avoid selecting performance or injury variables arbitrarily and to provide the necessary theoretical basis for examining the relative importance of various factors that influence the outcome of a movement task. Several disadvantages of deterministic models, such as the use of subjective measures for the performance outcome, were discussed. It is recommended that exercise and sports biomechanics scholars should consider using deterministic models to help identify meaningful dependent variables in their studies.  相似文献   

足球运动员整体训练系统基础     

B.Π古巴  A.B.列克沙科夫 《首都体育学院学报》2011,23(1):1-5

对足球运动员在长期训练过程中身体准备的综合体系进行了分析。长期的研究结果表明,足球运动训练可以被划分为4个方面:1)单纯性身体活动的使用,2)不同目标训练过程的交替使用,3)较小训练周期固定结构的保留并作为训练过程的基础,4)专门性推动能力的有序发展。这4个方面可以有效地解决足球运动员全面身体准备的问题。  相似文献

C·B·苏哈廖夫  B·H·普利德金  姚颂平 《首都体育学院学报》2011,23(2):99-100

为使合格球队的训练和比赛过程更具有现代化,研究人员提出了增加远距离投篮有效性的结构内容模式,并将投篮训练作为运动员技、战术的组成部分。投篮训练是一项专门性训练,要在不同情况下完成不同方式的投篮练习。通过各种不同的训练方式来掌握投篮技术并提高投篮的准确性。该模式是用来为每一名选手选取远距离和超长距离投篮方式,完善投篮技术,选择技、战术行为,制定不同训练周期和阶段个人和全队的投篮训练。结论:提高篮球远距离投篮效果的模式可以达到如下目的:1)队员的有效安排;2)完善投篮技术;3)为每一名选手选择不同的投篮训练模式;4)每一名队员投篮准确性的数据资料可以为全队的战术安排提供参考;5)定性地规划每一名球员和球队的投篮训练并作为球队技、战术训练的主要组成部分。  相似文献   

Visualization of the moving Pareto frontier in DSS     

N. B. Brusnikina  A. V. Lotov 《Scientific and Technical Information Processing》2011,38(5):322-331

A new approach to decision support in a multiobjective problem arising in controlled dynamic system design is described. The approach basically extends the feasible goals method that implies specifying the goal point by visualizing the Pareto frontier that characterizes feasible objective values and objective tradeoffs to dynamic systems. The developed approach helps explore dynamic modifications of the Pareto frontier.  相似文献

Distributed knowledge acquisition for the automatic construction of integrated expert systems     

G. V. Rybina  A. O. Deineko 《Scientific and Technical Information Processing》2011,38(6):428-434

The authors discuss the problem of distributed knowledge acquisition for the construction of complete and consistent databases in integrated expert systems via the sharing of knowledge sources of different topologies (experts, problem-oriented texts, and electronic media in the form of databases). The emphasis is on the models, methods, and algorithms of distributed knowledge acquisition from databases as additional knowledge sources. The authors describe the architecture and basic facilities of distributed knowledge acquisition, which function as a part of the AT-TECHNOLOGY tool complex.  相似文献

Innovation informatization for state financial control bodies   总被引：1，自引：0，他引：1  

A. Ya. Bystryakov  V. V. Mizintseva 《Scientific and Technical Information Processing》2011,38(2):69-77

The lack of a unified system of innovative information support of the activity of state bodies and at the same time the need for quick, qualified, and motivated decisions determine the role of informatization for bodies of state financial control (SFC). The article considers the basic features of information supply to SFC bodies and the requirements imposed on information in the financial sphere; the basic objectives and problems of information supply; risks and problems in the process of informatization in the SFC system; and the ways to deal with the existing problems within the Unified Information Space to be formed in accordance with the Electronic State and the Efficiency of State Governance program (by 2015).  相似文献
