Early repolarization, left ventricular diastolic function, and left atrial size in professional soccer players

Recent data have suggested a relation among long-term endurance sport practice, left atrial remodeling, and atrial fibrillation. We investigated the influence of an increased vagal tone, represented by the early repolarization (ER) pattern, on diastolic function and left atrial size in professional soccer players. Fifty-four consecutive athletes underwent electrocardiography, echocardiography, and exercise testing as part of their preparticipation screening. Athletes were divided into 2 groups according to presence or absence of an ER pattern, defined as a ST-segment elevation at the J-point (STE) > or =0.1 mm in 2 leads. For linear comparisons average STE was calculated. Mean age was 24 +/- 4 years. Twenty-five athletes (46%) showed an ER pattern. Athletes with an ER pattern had a significant lower heart rate (54 +/- 9 vs 62 +/- 11 beats/min, p = 0.024), an increased E/e' ratio (6.1 +/- 1.2 vs 5.1 +/- 1.0, p = 0.002), and larger volumes of the left atrium (25.6 +/- 7.3 vs 21.8 +/- 5.0 ml/m(2), p = 0.031) compared to athletes without an ER pattern. There were no significant differences concerning maximum workload, left ventricular dimensions, and systolic function. Univariate regression analysis revealed significant correlations among age, STE, and left atrial volume. In a stepwise multivariate regression analysis age, STE and e' contributed independently to left atrial size (r = 0.659, p <0.001). In conclusion, athletes with an ER pattern had an increased E/e' ratio, reflecting a higher left atrial filling pressure, contributing to left atrial remodeling over time.

Orofacial/cerebral injuries and the use of mouthguards by professional athletes in Switzerland

The objective of the present study was to measure the occurrence of orofacial and cerebral injuries in different sports and to survey the awareness of athletes and officials concerning the use of mouthguards during sport activities. Two hundred and sixty-seven professional athletes and 63 officials participating in soccer, handball, basketball and ice hockey were interviewed. The frequency of orofacial and cerebral trauma during sport practice was recorded and the reason for using and not using mouthguards was assessed. A great difference in orofacial and cerebral injuries was found when comparing the different kinds of sports and comparing athletes with or without mouthguards. 45% of the players had suffered injuries when not wearing mouthguards. Most injuries were found in ice hockey, (59%), whereas only 24% of the soccer players suffered injuries when not wearing mouthguards. Sixty-eight percentage of the players wearing mouthguards had never suffered any orofacial and cerebral injuries. Two hundred and twenty-four athletes (84%) did not use a mouthguard despite general acceptance by 150 athletes (56%). Although the awareness of mouthguards among officials was very high (59%), only 25% of them would support the funding of mouthguards and 5% would enforce regulations. Athletes as well as coaches should be informed about the high risk of oral injuries when performing contact sports. Doctors and dentists need to recommend a more intensive education of students in sports medicine and sports dentistry, and to increase their willingness to become a team dentist.

Sport psychology: Needs and perspectives for research, education and application

Sport psychology has shown an increasing development in the past 25 years. A first focus is laid on the growth of research output as indicated by the number of publications. A more detailed analysis shows that some mainstream topics are very dominant in the international research literature whereas other themes are completely lacking. Possible biases are discussed as well as consequences for the body of knowledge in sport psychology. The need for a sound training in sport psychology is discussed in relation with the progress in sport psychology research. Different concepts of education in sport psychology with their respective background are compared and their impact on the development of sport psychology is discussed. The field of application, mainly in top level sport, is presented with a focus on professional standards and deontological codes. Conclusions are drawn with the aim to open new perspectives for research, education, and application of sport psychology.

Beta-alanine supplementation improves jumping power and affects severe-intensity performance in professional alpine skiers.

INTRODUCTION Supplementation with beta-alanine may have positive effects on severe-intensity, intermittent, and isometric strength-endurance performance. These could be advantageous for competitive alpine skiers, whose races last 45 to 150 s, require metabolic power above the aerobic maximum, and involve isometric muscle work. Further, beta-alanine supplementation affects the muscle force-frequency relationship, which could influence explosiveness. We explored the effects of beta-alanine on explosive jump performance, severe exercise energy metabolism, and severe-intensity ski-like performance. METHODS Nine male elite alpine skiers consumed 4.8 g/d beta-alanine or placebo for 5 weeks in a double-blind fashion. Before and after, they performed countermovement jumps (CMJ), a 90-s cycling bout at 110% VO2max (CLT), and a maximal 90-s box jump test (BJ90). RESULTS Beta-alanine improved maximal (+7 ± 3%, d = 0.9) and mean CMJ power (+7 ± 2%, d = 0.7), tended to reduce oxygen deficit (-3 ± 8%, p = .06) and lactate accumulation (-12 ± 31%) and enhance aerobic energy contribution (+1.3 ± 2.9%, p = .07) in the CLT, and improved performance in the last third of BJ90 (+7 ± 4%, p = .02). These effects were not observed with placebo. CONCLUSIONS Beta-alanine supplementation improved explosive and repeated jump performance in elite alpine skiers. Enhanced muscle contractility could possibly explain improved explosive and repeated jump performance. Increased aerobic energy production could possibly help explain repeated jump performance as well.

What does professionalisation mean? Perceptions of professionalisation in swiss sport federations

Introduction: Organisational changes in sports federations are often associated with a drift from a volunteer driven to an increasingly business-like phenomenon (Shilbury & Ferkins, 2011). This process of transfor-mation is be called as “professionalization”. Accordingly, professionalization seems to be an appropriate strategy for sport organisations in order to meet organizational pressure due to challenges of a more complex and dynamic changing environment adequately. Despite the increasing research interest and the attempts for systematization on the phenomenon of professionalization it still remains unclear what does the term professionalization exactly mean (Dowling et al., 2014). Thus, there is a lack of a consistent concept of professionalization that is needed in order to explore different facets and perspectives of this phenomenon more validly. Against this background following question emerged: What is the suitable concept of professionalization for analyzing the actual ongoing processes of change, adaption or transformation in sport federations? Methods: Dealing with this question, following two-step approach was choosen: (1) In a first step a scholar’s perspective at professionalisation of sport organisations will be displayed in order to explore both the common ground as well as divergences and inconsistencies in previous approaches. Therefore, a literature review is indicated. (2) In a second step, and in contrast to previous studies we will consider a practical point of view by a so called second-order observation of experts to gain valuable insights into current thinking and acting towards professionalization in sport federations. In doing so, a hermeneutical approach is used, which is about understanding the meaning of contexts by grasping the everyday world, and draw insight and meaning from it (Shilbury et al., 2013). Accordance with hermeneutics, the explorative interpretive knowledge of expert interviews was used. The interviews were conducted with a sample of six selected experts, who have both dedicated insider knowledge and the overall view of all Swiss sport federations. Results and discussion: The summaries of literature review could be categorized into two research currents. The one defines professionalization as a structural process towards professional status of occupations. The other defines it in a broader sense as an organisational change towards a business-like approach. Whereas the first perspective there is a broad scientific consensus that second isn’t that clear, however. Explorative analysis of interview data reveals different themes in relation to professionalization of sports federation. First theme deals with a changed philosophy as more strategic alignment towards for-profit, efficiency and quality orientation. Second theme refers to paid work associated with more competence orientation and balanced governance between paid and voluntary work. Third theme deals with acting shift towards more rationalization and efficiency by implementation of innovative management and communication tools. Based on findings of both our review of scholar`s perspective as well insights from experts we will provide – in the sense of synthesis – a more clear understanding of what does professionalization mean that can be useful in terms of further studies.

Causes, forms and consequences of the professionalization of international sport federa-tions in Switzerland: Conceptual framework and first results

Synopsis: Sport organisations are facing multiple challenges originating from an increasingly complex and dynamic environment in general, and from internal changes in particular. Our study seeks to reveal and analyse the causes for professionalization processes in international sport federations, the forms resulting from it, as well as related consequences. Abstract: AIM OF ABSTRACT/PAPER - RESEARCH QUESTION Sport organisations are facing multiple challenges originating from an increasingly complex and dynamic environment in general, and from internal changes in particular. In this context, professionalization seems to have been adopted by sport organisations as an appropriate strategy to respond to pressures such as becoming more “business-like”. The ongoing study seeks to reveal and analyse the internal and external causes for professionalization processes in international sport federations, the forms resulting from it (e.g. organisational, managerial, economic) as well as related consequences on objectives, values, governance methods, performance management or again rationalisation. THEORETICAL BACKGROUND/LITERATURE REVIEW Studies on sport as specific non-profit sector mainly focus on the prospect of the “professionalization of individuals” (Thibault, Slack & Hinings, 1991), often within sport clubs (Thiel, Meier & Cachay, 2006) and national sport federations (Seippel, 2002) or on organisational change (Griginov & Sandanski, 2008; Slack & Hinings, 1987, 1992; Slack, 1985, 2001), thus leaving broader analysis on governance, management and professionalization in sport organisations an unaccomplished task. In order to further current research on above-mentioned topics, our intention is to analyse causes, forms and consequences of professionalisation processes in international sport federations. The social theory of action (Coleman, 1986; Esser, 1993) has been defined as appropriate theoretical framework, deriving in the following a multi-level framework for the analysis of sport organisations (Nagel, 2007). In light of the multi-level framework, sport federations are conceptualised as corporative actors whose objectives are defined and implemented with regard to the interests of member organisations (Heinemann, 2004) and/or other pressure groups. In order to understand social acting and social structures (Giddens 1984) of sport federations, two levels are in the focus of our analysis: the macro level examining the environment at large (political, social, economic systems etc.) and the meso level (Esser, 1999) examining organisational structures, actions and decisions of the federation’s headquarter as well as member organisations. METHODOLOGY, RESEARCH DESIGN AND DATA ANALYSIS The multi-level framework mentioned seeks to gather and analyse information on causes, forms and consequences of professionalization processes in sport federations. It is applied in a twofold approach: first an exploratory study based on nine semi-structured interviews with experts from umbrella sport organisations (IOC, WADA, ASOIF, AIOWF, etc.) as well as the analysis of related documents, relevant reports (IOC report 2000 on governance reform, Agenda 2020, etc.) and important moments of change in the Olympic Movement (Olympic revenue share, IOC evaluation criteria, etc.); and secondly several case studies. Whereas the exploratory study seeks more the causes for professionalization on an external, internal and headquarter level as depicted in the literature, the case studies rather focus on forms and consequences. Applying our conceptual framework, the analysis of forms is built around three dimensions: 1) Individuals (persons and positions), 2) Processes, structures (formalisation, specialisation), 3) Activities (strategic planning). With regard to consequences, we centre our attention on expectations of and relationships with stakeholders (e.g. cooperation with business partners), structure, culture and processes (e.g. governance models, performance), and expectations of and relationships with member organisations (e.g. centralisation vs. regionalisation). For the case studies, a mixed-method approach is applied to collect relevant data: questionnaires for rather quantitative data, interviews for rather qualitative data, as well as document and observatory analysis. RESULTS, DISCUSSION AND IMPLICATIONS/CONCLUSIONS With regard to causes of professionalization processes, we analyse the content of three different levels: 1. the external level, where the main pressure derives from financial resources (stakeholders, benefactors) and important turning points (scandals, media pressure, IOC requirements for Olympic sports); 2. the internal level, where pressure from member organisations turned out to be less decisive than assumed (little involvement of member organisations in decision-making); 3. the headquarter level, where specific economic models (World Cups, other international circuits, World Championships), and organisational structures (decision-making procedures, values, leadership) trigger or hinder a federation’s professionalization process. Based on our first analysis, an outline for an economic model is suggested, distinguishing four categories of IFs: “money-generating IFs” being rather based on commercialisation and strategic alliances; “classical Olympic IFs” being rather reactive and dependent on Olympic revenue; “classical non-Olympic IFs” being rather independent of the Olympic Movement; and “money-receiving IFs” being dependent on benefactors and having strong traditions and values. The results regarding forms and consequences will be outlined in the presentation. The first results from the two pilot studies will allow us to refine our conceptual framework for subsequent case studies, thus extending our data collection and developing fundamental conclusions.

European perspective on sport psychology

This chapter describes the development of sport psychology in Europe. Starting from the early years at the beginning of the 20th century, the contribution of European sport psychology in different cultural traditions to the development of this discipline is highlighted. The foundation of FEPSAC, the European Federation of Sport Psychology, and its role in this development are emphasised. During the first 20 years, Europe was a divided continent and the challenges were to establish a common understanding and possibilities for scientific exchange. After the fall of the Berlin wall and the change of the political landscape in Europe, central aims were to foster scientific exchange despite language difficulties, to develop a common understanding, to help young sport psychologists and to establish sport psychology as a professional field. In the new century, one group of challenges identified refers to unification, for example in education and training, in the services delivery, and in the structure. The second group of challenges relates to diversification, be it in the educational and vocational pathways, the different sports and physical activities, the inclusion of persons with special needs or background, or the publications.
