This study was conducted to determine the effects of inspiratory muscle training (IMT) on respiratory and peripheral muscles oxygenation during a maximal exercise tolerance test and on repeated-sprint ability (RSA) performance in professional women football players. Eighteen athletes were randomly assigned to one of the following groups: SHAM (n = 8) or IMT (n = 10). After a maximal incremental exercise test, all participants performed (on a different day) a time-to-exhaustion (Tlim) test. Peripheral and respiratory muscles oxygenation by near-infrared spectroscopy, breath-by-breath ventilatory and metabolic variables, and blood lactate concentration were measured. The RSA test was performed on a grass field. After a 6 week intervention, all athletes were reevaluated. Both groups showed increases in inspiratory muscles strength, exercise tolerance and RSA performance, however only the IMT group presented lower deoxyhemoglobin and total hemoglobin blood concentrations on intercostal muscles concomitantly to an increased oxyhemoglobin and total hemoglobin blood concentrations on vastus lateralis muscle during Tlim. In conclusion, these results may indicate the potential role of IMT to attenuate inspiratory muscles metaboreflex and consequently improve oxygen and blood supply to limb muscles during high-intensity exercise, with a potential impact on inspiratory muscle strength, exercise tolerance and sprints performance in professional women football players.  相似文献

Is passive drag dependent on the interaction of kayak design and paddler weight in flat-water kayaking?

Abstract

Drag is one of the major factors that influences kayaking performance. To focus on the drag of the kayak’s hull shape and the paddlers’ weight per se, the passive drag (D_p) was measured on a flat-water sprint course for one paddler with added weights. D_p was measured by an electromechanical towing device using a load cell, at incremental and constant velocities from 2.78 to 5.56 m/s. Three kayaks of different sizes and shapes (Nelo® K1 Quattro-M, ML, and L) were used and the paddlers’ body weight was adjusted with weights so the total paddler weight in the kayak was 65, 75, and 85 kg. The mean D_p increased by the power function of D = kvⁿ (mean R² = .990; SD .006). The D_p went from 21.37?±?1.29 N at 2.78 m/s to 89.32?±?6.43 N at 5.56 m/s. For the two lighter weighted kayaks (65 and 75 kg), the lowest D_p was observed with different kayak sizes (M, ML, or L) depending on the target velocity. The manufacturers suggest that paddlers should select a kayak size according to their body weight to minimise drag; however, the results of this study suggest that target velocities, and thus competition distance should also be factored into kayak selection.  相似文献

Rethinking library service to distance education students: analyzing the embedded librarian model     

Sullo E  Harrod T  Butera G  Gomes A 《Medical reference services quarterly》2012,31(1):25-33

Since fall 2009, reference librarians at The George Washington University's Himmelfarb Health Sciences Library have been embedded in online classes through Blackboard within the School of Nursing and School of Medicine and Health Sciences. The authors sought to determine the types of questions asked of the librarian, with the goal of informing future interactions with distance education classes to help develop a standard "protocol" for working with this population of students. Eighty-two questions were categorized and qualitatively analyzed. The findings have prompted librarians to explore tools such as Elluminate Live!, a tool that allows librarians to provide synchronous instruction within the Blackboard environment.  相似文献   

The social condition of higher education: globalisation and (beyond) regionalisation in Latin America     

Alfredo M. Gomes  Susan L. Robertson  Roger Dale 《Globalisation, Societies & Education》2012,10(2):221-245

This article aims to discuss the relationship between higher education (HE), globalisation and regionalism projects focusing on HE in Latin America and Brazil. It is claimed that HE has predominantly taken the diverse, yet concerted and co-ordinated routes of globalisation and regionalisation and, by doing so, been profoundly transformed. The first section considers a set of theoretical categories in relation to the phenomena of globalisation and regionalisation. The second section analyses the global and regional dimensions of HE in Latin America, exploring: (1) the Common Market of the South (MERCOSUR), along with the processes and mechanisms put into place to settle MERCOSUR's Educative Sector. It is argued that despite the political relevance of this regional project, its major developments are still harbouring important but preliminary preparations for future regional positioning and empowerment; (2) it is argued that the commodification, privatisation and ‘marketisation’ of HE, having occupied the centre stage in determined nations of the world, have become the founding conditions of a global market in HE; and (3) the Brazilian HE policies are examined in order to develop an argument about the decisive role played by national government in promoting and adjusting the process of globalisation and the regionalism project for HE.  相似文献   

Expanding Our Roles: Embedded in Curriculum Design     

Gisela Butera  Alexandra W. Gomes  Seema Kakar 《Medical reference services quarterly》2013,32(3):292-301

This article describes how librarians became involved as members of an interdisciplinary curricular team in a problem-based learning course for first- and second-year medical students. The experience illustrates how librarians can become part of a team, collaborating with medical faculty to assist in revising curricula, incorporating innovative teaching techniques, and creating effective simulated patient case scenarios. Working within an interdisciplinary collaborative team on curriculum development allows librarians to move beyond the traditional role of instruction and can lead to additional opportunities, including research and ongoing involvement in curricular changes.  相似文献
