Purpose: The purpose of this investigation was to examine the effects of a submaximal running warm-up on running performance in male endurance athletes (n = 16, Mage = 21 ± 2 years, MVO2max = 69.3 ± 5.1 mL/kg/min). Method: Endurance performance was determined by a 30-min distance trial after control and submaximal running warm-up conditions in a randomized crossover fashion. The warm-up began with 5 min of quiet sitting, followed by 6 min of submaximal running split into 2-min intervals at speeds corresponding to 45%, 55%, and 65% maximal oxygen consumption (VO2max). A 2-min walk at 3.2 km/hr concluded the 13-min warm-up protocol. For the control condition, participants sat quietly for 13 min. VO2 and heart rate (HR) were determined at Minutes 0, 5, and 13 of the pre-exercise protocol in each condition. Results: At the end of 13 min prior to the distance trial, mean VO2 (warm-up = 14.1 ± 2.2 mL/kg/min vs. control = 5.5 ± 1.7 mL/kg/min) and mean HR (warm-up = 105 ± 11 bpm vs. control = 67 ± 11 bpm) were statistically greater (p < .001) in the warm-up condition compared with the control condition. The distance run did not statistically differ (p = .37) between the warm-up (7.8 ± 0.5 km) and control (7.7 ± 0.6 km) conditions; however, effect size calculation revealed a small effect (d = 0.2) in favor of the warm-up condition. Thus, the warm-up employed may have important and practical implications to determine placing among high-level athletes in close races. Conclusions: These findings suggest a submaximal running warm-up may have a small but critical effect on a 30-min distance trial in competitive endurance athletes. Further, the warm-up elicited increases in physiological variables VO2 and HR prior to performance; thus, a submaximal specific warm-up should warrant consideration. 相似文献

Although many environmental and science educators have explored students’ conceptual understandings, misconceptions, and knowledge of the greenhouse effect, global warming, and climate change, few have investigated the ways students conceptualize climate as a system or how components of the system influence climate. Therefore, the purpose of this study was to begin the process of understanding how US students conceptualize a climate system. A total of 42 seventh grade students (ages 12–13) from the Midwest completed an open-response task. From the inductive analysis of student written responses, 22 codes emerged that reflected students’ conceptions of the climate system. From these codes, three path diagrams were constructed that illustrate these students’ conceptions about how a climate system influences climate and how greenhouse gases and global warming impact the climate system. A generalized model of students’ conception of a climate system was generated. Students in this study conceptualized a climate system in a unidirectional, linear, cause and effect relationship that emphasized the atmospheric component of the climate system. 相似文献

HILJ readers may have encountered the phrase library 2.0 which has polarised librarians, with some sceptical whether library 2.0 offers anything new. Others are confident that the convergence of service goals and ideas with emerging Web 2.0 technologies will lead to a new generation of library services. Andrew Tattersall's article, 'How the Web was Won', belongs in the latter camp. His thesis is that Web 2.0 and Library 2.0 have opened up a whole new world for exploration by information and library professionals. Although the Web has created problems for the modern day explorer, potentially there is a bright future for information professionals if they are to succeed in deploying the resources. 相似文献

ABSTRACTThis article reprises and reflects on 30 years of the author’s work on teacher collaboration. The distinctive nature of this work has not been in making a case for teacher collaboration in terms of its benefits for students, teachers, or educational change. These arguments are widely available elsewhere. Rather it has examined ways of collaborating that are available to teachers, how formal or informal collaboration should be, how collaborative efforts can be misused or misdirected, and what factors must be considered when deliberately designing teacher collaboration so it will have the most beneficial effects. The article discusses the explanatory and strategic power of three concepts in particular—contrived collegiality, professional capital, and collaborative professionalism. Conclusions are drawn about next steps for educational research in terms of establishing clear typologies of teacher collaboration in relation to their impact and appropriateness in different circumstances. 相似文献

Over the last 25 years many educators have stressed the need for students to learn about global issues and have often taken this to be a relatively unproblematic area of pedagogy. An important Canadian study on the impact of teaching about such issues, however, suggests that the learning process may be much more complex than was previously assumed. This article reports on a pilot research project in the UK which monitored student responses to learning about global futures and found much more going on beneath the surface than meets the eye. It would seem that strong cognitive, affective and existential responses need to be recognised and acknowledged as part of any journey towards personal and political change. 相似文献

University spin-out companies and venture capital 总被引:1,自引:0,他引:1
The creation of university spin-out companies that create wealth is a major policy objective of governments and universities. Finance is a catalyst of this wealth creation yet access to venture capital is a major impediment faced by these companies. In this article we adopt a finance pecking order perspective to examine the problems faced by those university spin-out companies seeking to access venture capital. We triangulate evidence from spin-out companies, university technology transfer offices and venture capital firms in the UK and Continental Europe to identify the problems and to suggest policy developments for these parties as well as government. We compare perceptions of high-tech venture capital firms that invest in spin-outs with those that do not, and also consider VCs’ views on spin-outs versus other high-tech firms. Our evidence identifies a mismatch between the demand and supply side of the market. In line with the pecking order theory, venture capitalists prefer to invest after the seed stage. However, in contrast to the pecking order theory, TTOs see venture capital as more important than internal funds early on. We develop policy implications for universities, technology transfer offices, academic entrepreneurs, venture capital firms and government and suggest areas for further research. 相似文献
