Prediction of maximal oxygen uptake in sedentary males from a perceptually regulated, sub-maximal graded exercise test 总被引:2,自引:0,他引:2
The purpose of this study was to assess the validity of predicting the maximal oxygen uptake (VO2(max)) of sedentary men from sub-maximal VO2 values obtained during a perceptually regulated exercise test. Thirteen healthy, sedentary males aged 29-52 years completed five graded exercise tests on a cycle ergometer. The first and fifth test involved a graded exercise test to determine VO2(max). The two maximal graded exercise tests were separated by three sub-maximal graded exercise tests, perceptually regulated at 3-min RPE intensities of 9, 11, 13, 15, and 17 on the Borg ratings of perceived exertion (RPE) scale, in that order. After confirmation that individual linear regression models provided the most appropriate fit to the data, the regression lines for the perceptual ranges 9-17, 9-15, and 11-17 were extrapolated to RPE 20 to predict VO2(max). There were no significant differences between VO2(max) values from the graded exercise tests (mean 43.9 ml x kg(-1) x min(-1), s = 6.3) and predicted VO2(max) values for the perceptual ranges 9-17 (40.7 ml x kg(-1) x min(-1), s = 2.2) and RPE 11-17 (42.5 ml x kg(-1) x min(-1), s = 2.3) across the three trials. The predicted VO2(max) from the perceptual range 9-15 was significantly lower (P < 0.05) (37.7 ml x kg(-1) x min(-1), s = 2.3). The intra-class correlation coefficients between actual and predicted VO2(max) for RPE 9-17 and RPE 11-17 across trials ranged from 0.80 to 0.87. Limits of agreement analysis on actual and predicted VO2 values (bias +/- 1.96 x S(diff)) were 3.4 ml x kg(-1) x min(-1) (+/- 10.7), 2.4 ml x kg(-1) x min(-1) (+/- 9.9), and 3.7 ml x kg(-1) x min(-1) (+/- 12.8) (trials 1, 2, and 3, respectively) of RPE range 9-17. Results suggest that a sub-maximal, perceptually guided graded exercise test provides acceptable estimates of VO2(max) in young to middle-aged sedentary males. 相似文献

This article analyses creative industries policy in the English regions under New Labour (1997–2010). It examines the ideas behind regional creative industries policies (RCIPs) and their implementation. Focusing on the activities of the English regional development agencies, the primary bodies responsible for the implementation of creative industries policy in the British regions, the article places regional cultural policy during the New Labour period within its broader political, social and economic contexts. It explains and evaluates New Labour's RCIPs, arguing that creative industries policy at the regional level changed over the course of New Labour's three terms of office, becoming increasingly economistic at the expense of a more social democratic vision of regional equality and democracy. We identify three issues that were problematic for New Labour's RCIP: a reliance on the idea of “clusters”, commercialisation and shifting regional governance. 相似文献

In the years since Michael Brown’s death, the hashtag #HandsUpDontShoot has been criticized for supposedly misrepresenting forensic evidence as framed by the Department of Justice. However, an expressive pull has kept alive both the hashtag and the sentiment behind it. The images of #HandsUpDontShoot are compelling in that they offer a glimpse into lived experiences that are often dismissed, ignored, or refuted. In this essay, I trace the aesthetic features of the #HandsUpDontShoot images, which foreground shocking juxtapositions between nonviolent protesters and militarized police forces, to the hashtag’s historical analogue: antilynching photography. Antilynching photography often utilized the aesthetic techniques of remediation, recontextualization, and juxtaposition—aesthetic features used prominently in today’s digital and remix cultures. By noting #HandsUpDontShoot’s use of these same techniques, I illuminate the ways in which Twitter’s connective affordances shape the viewer’s encounter with the images to engender ethical witnessing by affectively linking Brown’s death to shared material experiences of racial minorities. Such encounters propel witnesses beyond distanced objectification and toward an embodied reckoning of those experiences. 相似文献

This article draws on findings from my doctoral research to exemplify some of the difficulties I encountered when interviewing 20 female professors1 and subsequently writing about their life histories. In this article, I discuss how I addressed the issues of representing and positioning my participants, and I reflect on the power dynamics present in the research process. The article contends that by drawing on Bourdieu and Wacquant's [An Invitation to Reflexive Sociology. Chicago, IL: University of Chicago Press] understanding of reflexivity and feminist interpretations of their work including McNay [“Gender, Habitus and the Field: Pierre Bourdieu and the Limits of Reflexivity.” Theory Culture Society 16: 95] and Adkins [“Reflexivity Freedom or Habit of Gender?” Theory Culture Society 20: 21], valuable research can be produced, despite the difficulties. A related aim of this paper is to reflect back after four years in an academic post on my position as a novice researcher, and some of the associated issues facing doctoral students, particularly the problems with researching upwards [Walford, G. 2011. “Researching the Powerful. British Educational Research Association On-line Resource.” Accessed March 17, 2014. www.bera.ac.uk/system/files/Researching%20the%20Powerful.pdfWalford 2011]. 相似文献

Robust academic research on the topic of students involved in the sex industry is in its infancy, yet the relationship appears consistent and permanent. This paper draws on findings from the largest study into the stripping industry in the United Kingdom to explore the relationships between students, sex work and consumption. To make sense of the relationship between students and participation in the sex industry, a deeper understanding of other social and cultural processes is needed. In this discussion we argue that the following points are relevant and interlinked: changes to the nature of sexual commerce and sexual consumption as they become part of the marketplace; changes in social attitudes and the rise of ‘respectability’ in sexual commerce; the ‘pleasure dynamic’ amongst students; and changes in the higher education structure that place students as consumers as well as financially fragile. We set out a future research agenda given that this relationship is set to grow as the individual bares the cost of higher education. 相似文献

Three of the most prevalent developmental disorders (DDs) are autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD) and fetal alcohol spectrum disorder (FASD). As part of a study screening for DDs in Greater Manchester, UK, a unique opportunity was taken to explore parents' experiences of receiving reports about their child's previously unrecognised DD. Six parents out of a possible 16 took part in interviews, which were analysed thematically. Findings drawn from parental responses revealed a number of barriers to accessing support for their child's additional needs, including perceived resistance from schools, particularly for quiet, well-behaved girls, and difficulty in accessing assessment or referrals. There needs to be greater awareness of additional needs in children without externalising behaviours, the presence of gender-specific differences in the presentation of DDs, and FASD as a commonly occurring DD. Ultimately, better support for children with DDs would reduce the burden of unmet needs for the children and their families, and for wider services. 相似文献
