Analysis of repeated high-intensity running performance in professional soccer

Abstract

The aims of this study were twofold: (1) to characterize repeated high-intensity movement activity profiles of a professional soccer team in official match-play; and (2) to inform and verify the construct validity of tests commonly used to determine repeated-sprint ability in soccer by investigating the relationship between the results from a test of repeated-sprint ability and repeated high-intensity performance in competition. High-intensity running performance (movement at velocities >19.8 km · h^?1 for a minimum of 1 s duration) was measured in 20 players using computerized time–motion analysis. Performance in 80 French League 1 matches was analysed. In addition, 12 of the 20 players performed a repeated-sprint test on a non-motorized treadmill consisting of six consecutive 6 s sprints separated by 20 s passive recovery intervals. In all players, most consecutive high-intensity actions in competition were performed after recovery durations ≥61 s, recovery activity separating these efforts was generally active in nature with the major part of this spent walking, and players performed 1.1 ± 1.1 repeated high-intensity bouts (a minimum of three consecutive high-intensity bouts with a mean recovery time ≤20 s separating efforts) per game. Players reporting lowest performance decrements in the repeated-sprint ability test performed more high-intensity actions interspersed by short recovery times (≤20 s, P < 0.01 and ≤30 s, P < 0.05) compared with those with higher decrements. Across positional roles, central-midfielders performed more high-intensity actions separated by short recovery times (≤20 s) and spent a larger proportion of time running at higher intensities during recovery periods, while fullbacks performed the most repeated high-intensity bouts (statistical differences across positional roles from P < 0.05 to P < 0.001). These findings have implications for repeated high-intensity testing and physical conditioning regimens.     

Including students with disabilities in Education for All: lessons from Ethiopia

This article addresses the inclusion of students with disabilities into the Education for All and Sustainable Development Goals agenda through a case study of Ethiopia, a country aiming to promote inclusive education amidst rapidly rising school enrolments. The article begins with a review of debates concerning inclusive education in the Global South and the strategy taken by Ethiopia. It then examines how inclusive education is currently being implemented drawing on recent fieldwork at rural and urban schools in Tigray province. Through interviews, participant observation, and focus groups, we found that teachers and school administrators are generally in favour of mainstreaming children with disabilities into ‘normal’ schools. However, insufficient training of teachers and itinerant teachers along with shortages of teaching materials and resources present major challenges to addressing special education needs.

THE FINANCIAL PARTICIPATION OF ENTERPRISES IN THE FUNCTIONING OF FRENCH HIGHER EDUCATION INSTITUTIONS

The article discusses and tries to reconcile two phenomena; that, on one hand, in France, higher education is seriously underfunded, and that, on the other hand, public and private sector enterprises are experiencing shortages in the availability of highly qualified senior staff. At the same time, the need to obtain funding for higher education from sources other than the public authorities is recognized. Ways in which business may contribute to the funding of higher education are discussed, stress being laid on the use of the so‐called apprenticeship tax collected from enterprises and used to support higher education in given areas of training. The functioning and the receipts of this tax are analysed from a neo‐liberal perspective in terms of regional economic development, the types of institutions and programmes which receive subsidies from it, and amount per student. One obvious conclusion is that enterprises are loathe to contribute to the financing of initial education. On the other hand, since they are increasingly willing to finance specific and specialized training, universities, as distinct from other types of higher educations institutions in France, but having the necessary facilities and teaching staff, have been able to seize opportunities offered them to create special further training courses of use to enterprises. Hence, universities receive the largest share of the receipts of the apprenticeship tax.     

Do handball throws always exhibit a proximal-to-distal segmental sequence?

Previous studies on overarm throwing have described a proximal-to-distal segmental sequence. The proximal segments reached their maximal linear velocities before the distal ones. In handball, no study has demonstrated this sequence from the upper torso to the wrist, although a recent study did present a different organization. The aim of this study was to analyse the throwing arm segmental organization during handball throwing. We found that the maximal linear velocity of the shoulder occurred after the maximal linear velocity of the elbow. Moreover, the maximal angular velocity of the upper torso occurred later than that of the elbow. Hence, contrary to other disciplines, the rotation of the upper torso was not suddenly stopped just after the forward arm motion was initiated. These results may apply to handball in general or be specific to the population of handball players studied. It may be advisable in future studies to include international players.     

Challenging the concept of ethical literacy within Education for Sustainable Development (ESD): storytelling as a method within sustainability didactics

Ethical literacy seems to be used, within Education for Sustainable Development (ESD), in various ways, some more general and others morally specific, emphasising individuals’ responsibility. The overarching aim of this paper is to present some prerequisites for the development of narrative methods that focus on the vision of a good society without compromising individual integrity. Is it possible to develop ESD in a ways that highlight global challenges with a focus on justice and equity without either, as within post-political romanticism, pretending that social sustainability is a non-controversial ethical goal, or, as within liberal individualistic approaches, claiming that no one may escape from the demands of action competence, which, it is claimed, paves the way for making social sustainability a reality? With reference to some threads in narrative theory and by an analysis of six children’s books, this paper critically and constructively examines storytelling as one method to inspire young people to reflect upon what a good society and a good world might be, to catch sight of visions of a sustainable world and of the differences between how things are and how things could be – a method that may also preserve respect for individuals’ integrity.     

The Role of Patriotism in Explaining the TV Audience of National Team Games—Evidence From Four International Tournaments

In the literature addressing the determinants of TV audiences in sports, both the absolute and relative playing strength of the opponents play a prominent role. Regarding national team competitions, however, this study conjectures that patriotism matters as well. Analyzing the Swiss TV audience at 2 World Cups and 2 European Football Championships, this study finds strong evidence that TV ratings are highly affected by the sizes of the groups of foreign residents affiliated with the teams playing on the field.     

Performance and acceptance when using tablets as a multiple document learning tool: do application and guidance matter?

This study addressed whether an application adapted to working with multiple documents implemented in an iPad Pro tablet would promote students’ multiple document comprehension and acceptance of tablets as a multiple document learning tool relative to controls who used a traditional application adapted to sequential reading of single documents. Results indicated that students using the multiple document reading application outperformed the control students in terms of comprehension and also worked more efficiently on the assigned multiple document task, but only if given explicit guidance in selecting, organizing, and integrating information by utilizing the functions of the application. Still, after task completion, the more effective and efficient students guided in using the functions of the multiple document reading application displayed much less acceptance of tablets as a multiple document learning tool than did the control students. We discuss possible explanations for this intriguing performance-acceptance paradox and suggest some avenues for future research in this area.

     

Digitalizing consumer society: equipment and devices of digital consumption

ABSTRACT

This special issue of the Journal of Cultural Economy focuses on the digitalization of consumption and its social, cultural, ethical, political, and gendered implications. It thus answers the call for more research on how digital devices spread from the purely personal domain to multiple sociocultural domains. Through their use, new cultural practices have emerged between consumers and these devices, and devices and markets, that lead to change, in terms of consumer demand, consumption norms, and issues of ethics, culture, and power. Closely examining the role that devices play in consumption behavior enables us to address the supposed manipulative power of hi-tech companies, infrastructures, and systems at the global level, and the view ordinary market actors hold of digital appliances as empowering tools at the local level. The papers in this volume bridge ‘actor network theory' and ‘consumer culture theory' from the perspective of market ‘agencements.’ Ruckenstein-Granroth and Beauvisage-Mellet, and Arriagada-Concha focus on the device-mediated relationship between large digital market infrastructures and consumer behavior; Petersson McIntyre and Licoppe unveil the societal and cultural underpinnings of digitalized markets. Last but not least, Sörum and Soujtis address the political dimensions and implications of our new digital consumer equipment and society.
