Full textAbstract:
In recent years has been a rapidly growing increase in the popularity of extreme sports. Whilst the root of the exact reasons that extreme sports have grown so dras;cally as an industry is not en;rely clear, there are many theories and sugges;ons which can create a narra;ve to the evolu;on of the sports. Not only have the sports become more popular, but the varie;es of the sports and the varie;es of the par;cipants have also increased, crea;ng more diversity and the evolu;on of a extreme sports culture. This has coincided, inten;onally or un-inten;onally, with the glamorisa;on and commodifica;on of extreme sports lifestyles and the technological advancements of the twenty-first century. In line with the above, the purpose of this study, and the photographic project which accompanies it, is to examine; • What are the factors that contribute to the popularity of extreme sports • Who takes part in extreme sports • Why do people take part • What is the future for extreme sports and it’s par;cipants The photographic project comprises of four photographs of each par;cipants, two of which are portraits and two of which are supplied by the par;cipants themselves. The inten;on of the photographs is to give insight into both who the par;cipants are as individuals and as athletes and how they view themselves within these roles. Interviews were also conducted alongside which are referenced throughout the paper. The paper combines the research and theories of other scholars, against the findings of my own study and how the photographic project represents this, to try and draw answers to the above state ques;ons. The results were varied and did not offer full answers but rather sugges;ons into where more research could be done to further this study and future studies. Most notably; Extreme sports and femininity, Extreme sports and diversity, Extreme sports and classism and Extreme sports and environmentalism.

Full textAbstract:
In the past two decades, the popularity of Extreme Sport (X-Sport) has rapidly increased in Hong Kong. “Exploration of Excitement” would be the main reason why teenagers and young adults would like to play X-Sport. Unlike other sports, X-Sport does not require any rules, restrictions or physical requirements for its players, which provides more freedom and creativity. However, the general public does not agree with this particular interest group due to their misunderstanding with limited knowledge of the X-Sport. Also, there are only few existing X-Sport park and related facilities in Hong Kong and most of them are located at unwanted spaces with poor environmental and facilities qualities, which leads X-Sport player would play at local parks and unused space in their neighbourhood. Damages on landscape feature are normally appeared in these local parks recreational spaces. Due to the lack of societal supports and deficiencies in government, there are only six existing X-Sport park in Hong Kong, where they are all inaccessible and far apart. This thesis aims to promote X-Sport by using an X-Sport park as a median to integrate both young and old generations in physical and social aspects, not just exists as a functional space for X-Sport players. A roundabout site, Chai Wan Roundabout Garden, in major transport interchange in Hong Kong Island is selected for the development of this concept. Three stages design process has been incorporated. The first design stage has developed based on the primary site-observation and comprehensive site analysis. The second design stage is to conduct a special study of a landscape technique with both local and international case studies. The third design stage is to combine both first and second stages development and formulate the final design solution. Comments from first and second juries has been addressed and amended accordingly.published_or_final_version

Gieseler, Carly Michelle. "Performances of Gender and Sexuality in Extreme Sports Culture." Scholar Commons, 2012. http://scholarcommons.usf.edu/etd/4049.
Full textAbstract:
The purpose of this study is to expose the strategies through which extreme sports constitute gender through exaggeration, parody, queering, resistance, and transcendence of normative gendered binaries. I interrogate how extreme sports operate on the margins of sport, gender, media, and lived experience to better understand the processes and performances that retain, reinforce, and resist our notions of normative gender, bodies, and sexuality. Starting with the claim that performance is constitutive of gender and culture, I will focus on how extreme sporting performances create significant commentaries on mainstream assumptions surrounding sporting gender, sexuality, and corporeality.
These commentaries function in extreme sports' spaces: to critique how extreme sports reclaim oppressive language of gendered binaries; to give voice to sexual silences in performances that lampoon, retrofit, and transcend those assumptions; and, for athletes to reclaim corporeality through strategies of parody, resistance, and elision. Taking up the transcendent possibilities for gender, body, and sexuality in extreme sports, I suggest that these are also places to reimagine a phallocentric combat myth, revisit issues of class and performance, and speak of the invisibility of racial difference.
Using critical analysis, interviews, and personal narrative, I explore performances of gender, sexuality, and the body in mediated and live extreme events beginning with the revival of the roller derby phenomenon exemplified in the 2007 documentary Hell on Wheels, the 2006 A&E series Rollergirls, and the multiple websites, leagues, and fictional representations such as 2009's Whip It. I then turn to MTV's pranktainment playground of Jackass, Viva la Bam and Nitro Circus as well as the traveling motocross spectacle Nuclear Cowboyz. Finally, I attend to the extreme bodies of ultradistance running through multiple texts and conversations with runners as well as my own participation in the 2011 Keys100 in the Florida Keys.
My study will not repeat the many questions, critiques, or concerns of foundational or traditional scholarship on sports, media, or risk. Instead, I focus on several key issues across the chapters: how sport is housed as always already a masculine realm, how mainstream and extreme sports do gender corporeally, and the ways extreme sports challenge our mainstream notions of sexualities.

Sparks, Jacob Ray. "Extreme Sports: A Study of Free-Solo Rock Climbers." BYU ScholarsArchive, 2016. https://scholarsarchive.byu.edu/etd/6136.
Full textAbstract:
Extreme sport participation has traditionally been conceptualized as a psychological disorder and something to be avoided (Cashmore, 2002). Viewed in this way, these individuals are thought to be enacting an unhealthy psychology (Ogilvie, 1997; Slanger & Rudestam, 1997). Other research has described participants in extreme sports as sensation seekers under-stimulated by their normal surroundings and out of control (Zuckerman, 1979). Using Brymer's (2005) focused definition of extreme sports, "activities where a mismanaged mistake or accident would most likely result in death, as opposed to injury" (p. 5), this study utilized a phenomenological method to analyze semi-structured interviews with 16 free-solo climbers (n =16). The participants described their motivations in terms of overwhelming enjoyment, heightened focus, and personal progress. These results support more recent research describing extreme sport experiences as opportunities for positive transformation with outcomes including gains in courage, humility, eco-centrism, and emotional engagement (Brymer, 2009; Willig, 2008). These findings challenge the traditional, stereotypical notions of extreme sports participants as young and male (Wheaton & Beal, 2003), sensation-seeking (Zuckerman, 1979), and psychologically unwell (Ogilvie, 1997; Slanger & Rudestam, 1997). Answering Brymer's (2005) call to investigate all extreme sports individually, this study focused on the specific extreme sport of free-solo climbing and found the experience of the free-solo climber is a powerful undertaking enjoyed by young, old, male, and female.

Full textAbstract:
This paper is a study of the aspects that are important to consider when designing an unobtrusive interaction for wearable devices in the area of extreme sports. The work is based on an analytical study of seemly-unrelated areas with the common facet that they all call for an unobtrusive interaction in their devices. The findings of the analysis conclude that it is necessary a change of direction in the design because it is not possible to design an unobtrusive interaction that relies on active manipulation. Activity theory and affective computing present theoretical principles with the potential to be used as a framework for HCI and solve the mentioned issues. Finally, I design the user interface of a specific case in the areas of mountain biking and skiing to use it as design-oriented research. An essential aspect of this case is the use of expert feedback and video simulations to drive the design process. Another important point is the definition of the situations and variables that will be observed by the system to adapt itself so it is able to continue being unobtrusive and helpful through the changes.

Gipson, Christina Marie. "Extreme volunteering : a holistic perspective on international women sport volunteers." Thesis, Brunel University, 2012. http://bura.brunel.ac.uk/handle/2438/6566.
Full textAbstract:
This thesis explores the lives of a group of fifteen exceptional women who were dedicated to the cause of advancing girls and women in sport and physical activity. Over several decades, they worked in a voluntary capacity to transform women in sport through practice and policy development. Moreover, they aligned such unpaid work with personal and local experiences of volunteering that eventually led to their participation in international sport circles and policies. The key settings for their voluntary service came from their roles in the emergence and maintenance of two international women‘s sport organisations – International Association of Physical Education and Sport for Girls and Women (IAPESGW) and WomenSport International (WSI). In addition, their voluntary roles were so substantial that they were inextricably interwoven within all aspects of their lives. Therefore, the purpose of this thesis is to explore the participants‘ relationships with sport volunteering, in the particular settings of IAPESGW and WSI, whilst analysing the role of volunteering in their lives. The study utilised a holistic framework to gain an in-depth understanding about the women‘s commitment to the cause and how volunteering fits into their lifestyle. As there were no models from the sport volunteering field that were appropriate for this study, the research drew upon and developed Hustinx and Lammertyn‘s (2003) non-sport model called the Collective and Reflexive Styles of Volunteering (SOV). The SOV was valuable because it offered a multi-dimensional approach to explain how, why, and when the participants got involved with advancing women‘s sport and physical activity, and how their involvement related to and influenced their wider lifestyles. A critical realist and social constructionist philosophy was employed to have a greater understanding of the women‘s realities, and life history interviews were conducted to gain a greater understanding about how they constructed their knowledge about themselves, sport, and the world around them. The study illustrated the complexity of the women‘s volunteer participation. The findings suggested that their sport passion and identity guided many of their actions and activities throughout their life, such as choices for higher education and within professional work. In addition, the findings showed that it was their personal experiences and gained knowledge about gender disadvantages in sport that initially stimulated and then repeatedly reinforced their interests and commitment. Although these had strong impacts on the women‘s entrance into and commitment to the cause, the findings highlighted that the women had to identify the conditions of their relationships, family, and types of paid work to be compatible with levels of volunteering. The study concluded that sport researchers can benefit from examining volunteers from a holistic perspective to gain a better understanding of the conditions under which individuals make such an extreme, voluntary contribution to sport.

Full textAbstract:
Free sports are the phenomena that have rapidly developed from lifestyle activities to professional competitive sports over the last several decades. Known for distinctive counter-culture values, many popular free sports, such as snowboarding or BMX, have recently become largely commercialized and experienced significant organizational change. The main research question of this study is how free sports have organizationally evolved over time. This thesis focuses on patterns and mechanisms of structural change and evolution of values of these sports. The research utilized a multiple case qualitative methodology and is presented as a cross-case study of three international sports: competitive snowboarding, competitive skateboarding, and sport climbing. A review of existing literature identified the theory of new institutionalism as being particularly relevant to this study and thus, supplemented by resource-dependence theory, this forms the theoretical framework for this research. This study found that as a result of organizational evolution, informal organizational arrangements, which were historically typical for free sports, have not been uniformly replaced by formalized structural arrangements of mainstream sports. In addition, the organizational fields of these free sports are found to have adopted multiple logics, such as commercial, competitive, and traditional free sport logics. The notion of cultural legitimacy of international sport organizations appears to be central to explaining organizational evolution of free sports. As conflicts revolving over the “ownership” of international sports and the practice of “umbrella” governance are found to be of great concern in free sports, it is the relationship between cultural and regulatory legitimacy that these issues are addressed through. Finally, it is found that multiple power/dependence relationships existing in organizational fields of free sports are largely underpinned by commercial interests and strategies of the Olympic movement. In terms of contribution to theoretical knowledge, this study extends previous applications of institutional and resource-dependence theories to free sports and reveals that the process of institutionalization of sports does not necessarily lead to change of values in macro perspective. However, it can facilitate and foster a separation between two different “versions” of the same sports: competitive sports and traditional sports. This study contributes to wider practical sport management knowledge by raising a question of sustainability of culturally legitimate but unconventional international sport organizations in the global sport business. Another implication of this study is challenging the IOC as a source of regulatory legitimacy for sports and questioning the belief that all sports strive for the Olympic Games, which is taken for granted as the ultimate goal of evolution of sports in a global context. This is a major call of this study to both academics and practitioners, as governance of international sports is expected to remain the topic of a great debate in academic literature and popular media.

Participants in extreme sports have usually been studied from a risk perspective. The present study seeks to move away from this preconception and aims to study the emotional subjective experience. A qualitative methodology with phenomenological-hermeneutic design was used taking as a tool conversational systems. The informants were 8 extreme athletes belonging to the same group. Extreme sports included were: Mountain climbing, rappelling, bungee jumping, and mountaineering. The results indicate that fear is a generator of freedom, it can be useful, it is rewarding and it is also a promoter of personal transformations. This research gives theoretical value to the reason for involvement in extreme sports.

Full textAbstract:
Marketing in social media has been studied extensively in recent years, but not specifically for extreme-sport oriented companies. Even though most of the extreme-oriented companies are using social media for marketing, only a few pay special attention to its risks and possibilities. The purpose of this study is to identify extreme-sport oriented companies' practices to use social media as a marketing tool. I interviewed eight extreme- oriented companies and athletes. In addition to interviews, I also performed a four weeks observation in social media, mostly in Facebook and Twitter, and made notions about companies' practices in using social media for marketing. Almost all interviewed companies (88 %) were using social media. They usually posted updates about once a week and did not have a marketing strategy. However, it is possible that larger companies, which were not directly interviewed in this study, have a clear strategy for marketing in social media. Interviewed companies used social media in an improvised and unplanned manner. However, through trial and error, extreme-sport oriented companies have found their way to use social media effectively. Writing posts in social media about new products, upcoming events, offers, extreme-sport pictures or films and up-to-date information about the company seemed to be a good way to use social media for marketing. Most of the extreme-sport oriented companies can find social media a very useful marketing tool, but only if they have resources and time to invest to be active on social media.

Full textAbstract:
Snowboard media producers attempt to create subculturally relevant videos that connect with the audience. Videos provide the opportunity to report and document snowboarding activity, highlight new developments and provide visibility to prominent participants and associated businesses. Being a well-known and esteemed snowboarding participant is advantageous to being a producer, as it provides an identifiable cultural capital and implies a trustworthy ‘by-riders-for-riders’ philosophy. Connecting with the viewers is vital, as the audience plays a role in the distribution of videos by sharing and endorsing them through their social networks. Motivating factors in audience media sharing, also known as media spreading, include status seeking, improving credibility, personal satisfaction and personal expression.
Snowboarding was founded on anti-mainstream and anti-commercialism beliefs, which means that incorporating advertising and promotional messaging could negatively impact on audience connection. Yet, filming and producing snowboarding videos is difficult and expensive. Advertising represents an opportunity to attract funding and support to assist with production costs and, ultimately, provide profit. In order to accommodate advertising into their videos, producers are sometimes required to compromise their standards. This compromise represents a threat to audience connection. Producers believe that high quality, innovative snowboarding action footage provides the best opportunity to wow the audience. Various forms of advertising, including stealth marketing, sponsored journalism, and hybrid messaging, are often displayed in the moments between action footage shots, but advertising compromise can also affect action footage, particularly on client-funded projects. How advertising is incorporated can also depend on the industry the advertiser operates in. Alcohol brand advertising is identified as highly restrictive due to legal implications and public perceptions. Advertisers from businesses strongly related to the snowboarding subculture are more aware of their competitors’ presence in videos, which can cause conflict. Ski field support can be varied, despite high levels of visibility in the videos.

Lead users are proposed as a valuable resource for marketers in terms of the (1)
development, (2) adoption, and (3) diffusion of new products. We present the first consumer study
to provide evidence that the latter two suggestions are justified. First, we find that lead users
demonstrate stronger domain-specific innovativeness than more "ordinary" users. Second, lead
users perceive new technologies as less "complex" and might therefore be better prepared to adopt
them. Third, we find that lead users demonstrate stronger opinion leadership and weaker opinion
seeking tendencies. Finally, we discuss the implications of our findings for the marketing of new
products. (authors' abstract)

Full textAbstract:
The physicality of sports and outdoor life offers great opportunities for intensive experiences – participants ”feel” the happening in their bodies. As well as looking upon physical activity mainly as something instrumental, as for example in competitive sports and exercise culture, other aspects can also be central, for instance the pure joy of movement. The existential or expressive side of physical activity is examined in this doctoral thesis. In order to study such experiential quality more thoroughly, the author’s attention turns to adventure sports participants, as they appear to have a capacity for becoming highly involved and seeking very intense experiences. Who is involved in adventure sports? Why are they engaged in a sport that demands such great hardships and risk-taking? What do they get out of it? The overall objective of the thesis is to shed light on adventure sports as a practice and to discuss the educational significance of flow and other experiential qualities in adventure sports and in schools. The analyses are based on three empirical sub-studies. The first began with a questionnaire that 161 adventure sports participants responded to. This was followed by an interview study of eleven men and three women, all of whom had extensive experience in adventure sports. The categories of sport were evenly divided between climbing, off-piste skiing and hang gliding. In the second sub-study a detailed investigation of climbing was carried out. A notable sportification has brought about a very clear and interesting change in parts of this activity. Six traditional/adventure climbers and six sport climbers were interviewed, of which half were men and half women. All the climbers were experienced and very much involved in their sport. The aim of the third sub-study was to seek an answer as to whether pupils have experiences in their daily school life that are similar to those of adventure sports participants. An ESM (Experience Sampling Method) investigation was carried out with 60 pupils in compulsory school year nine (corresponding to UK schools’ year eleven) from four different schools. The pupils’ parents answered a special parent questionnaire including questions about academic and professional backgrounds, living conditions, habits, interests, attitudes and leisure time activities. The results were analysed taking into consideration the phenomenological perspective and structuralistic or more correctly expressed the cultural sociological perspective. Mihály Csikszentmihályi’s theoretical argument on optimal experiences, which in turn is based on the flow concept, constitutes the phenomenological foundation. Pierre Bourdieu’s concept apparatus and theories were used to closely examine the participants’ backgrounds, life histories and current living situations. The study shows that a preference for adventure sports is clearly linked to the participants’ backgrounds and earlier life experiences. A behavioural pattern is incorporated and developed into an embodied capacity to master a practice, a result of a long learning process. Participants were clearly concordant in these respects. Participants emphasise the abundant opportunities for intensive experiences that arise from adventure sports. It is a matter of something multidimentional: the active body, outdoor life in natural surroundings, exacting and clear goals, total focus, and about exercising control. This approach presents a model for identification of content qualities, which together create the dynamics that form the meaningful rewards that result from participation in adventure sports. The dimensions include flow experiences, but also go beyond them. The deep sense of presence, the physical involvement, the fact that they can choose the path and increase the degree of difficulty themselves – and simultaneously counter this new challenge with increased capacity so that they are engaged at the ”right level” – also provide favourable conditions for a stimulating and successful learning experience. The observation was made that it was primarily in the practical and aesthetic subjects that school pupils had the same deep feeling of presence together with a meaningful and pleasurable holistic experience as the adventure sports participants had. Here they were actively involved with their hands or with their whole bodies, and they could make their own choices and be in control of the activity, which for most pupils led to a strong feeling of satisfaction.

Full textAbstract:
The turn of the millennium has heralded an explosion in the popularity of adventure sports often also referred to as alternative lifestyle sports or extreme sports. These are offering both new avenues and potential challenges to the traditional ways of conceptualising and practicing sport. This thesis analyses the development of adventure sports, in particular climbing and kayaking, as a subculture. It delivers a socio-economic history of climbing, analyses the role of the media in its development, its participation and its lived experience. Further it investigates the impact of globalisation, commercialisation and consumerism on adventure sports, and considers to what extent they are being brought into the mainstream as a result. The economic impact of participation in adventure sports is reviewed along with a study of how the make up of its participants has changed as the activities have become more accessible. Particular focus is placed on the analysis of the gender order, specifically looking at the experiences of women in adventure sports. For this purpose the sports culture found in climbing and kayaking is examined and the implications for the reconstruction of gender relations are considered. This study employs an ethnographic approach including both semi-structured and structured interviews with both adventure sports experts and participants, document and media analysis, participant observation and the more recent nethnography approach. One of the significant contributions of this thesis has been to provide a comprehensive review and analysis of the social, cultural and media environment of arguably one of the most popular lifestyle sports in the UK. It has also shown the strong interrelationship that exists between the media and adventure sports, and has demonstrated how the increased commercialisation and commodification of the activity has resulted in economic development particularly in some remoter parts of the UK through the packaging and provision of the climbing experience. At the same time some participants see this is ‘selling out’. This research has demonstrated how women’s participation in adventure sports has been subject to marginalisation, sexualisation and trivialisation similar to other mainstream sports. However, this work has also highlighted that there is room for optimism as new discourses of femininity contrary to the traditional male hegemony are emerging. Further research opportunities have been identified concerning issues of ethnicity and participation; the social, cultural and economic relationships between adventure sportspeople and rural communities. Emerging feminist discourses also warrant further investigation.

Full textAbstract:
The purpose of this study was to discover what impact, if any, personal social networks have on an individual’s snowboarding skill progression, and whether any differences emerge based on gender, class, race, or age. Interviews with 10 demographically diverse snowboarders in Washington State, USA, were conducted and analyzed. The study revealed that personal social networks are highly important to snowboarding skill progression, with nine progression benefits noted. It was also found that the type of relationship was important, with the roles of gatekeepers, “godfathers,” and crews as the most critical for progression. Lastly, respondents indicated a variety of methods to access social networks, including social media, events, organizations, industry employment and through existing social networks. To further analyze the findings, an intersectional feminist reading of Castells networking theory was applied, with investigations into gender, race, class, and age patterns. The analysis revealed two overlapping values systems, one based on snowboarding ability and commitment, and one based on alignment of demographics with those who are most valued in the snowboarding world--mainly young, white, middle class men. The research closes with potential solution ideas to improve equitability and inclusion, which can be applied from the grassroots level to large-scale implementation.

Full textAbstract:
Projeto de Pós-Graduação/Dissertação apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Medicina DentáriaIntrodução: Estudos epidemiológicos indicam que o traumatismo dentário é um problema significativo em jovens 8-15 anos e que a sua incidência em determinadas faixas etárias pode ultrapassa o da cárie dentária e da doença periodontal. Deste modo, o traumatismo dentário é sinónimo de um problema de saude pública em que o seu aumento se deve sobretudo aos acidentes de viação, prática de desporto radical e até violência doméstica. Bem como os fatores etiológicos mais evidentes destacam a projeção labial e o overject aumentado. Objetivo: Pretende-se realizar uma revisão bibliográfica abordando os vários traumatismos dentários existentes, adquirir informações sobre etiologia, prevalências, relação de género e idade, factores associados, planos de tratamento emergente e contínuo, possíveis sequelas, prognósticos e prevenção. Materiais e Métodos: Pesquisou-se em duas bases de dados a literatura relevante quanto à temática proposta, com limite temporal dos últimos 7 anos (2007-2014) e com as seguintes palavras-chave: “dental trauma”, “tooth injuries”, “permanent teeth”, “prevalence”, “tooth avulsion”, “extreme sports”, “treatment”, “aesthetics”, “primary care”, “urgent care” em bases electrónicas de referência Medline, PubMed, SciELO e B-on. Completou-se com livros da especialidade existentes na Biblioteca da Faculdade de Ciências da Saúde da Universidade Fernando Pessoa e sites nacionais e internacionais de renome conceituado. Conclusões: O traumatismo dentário adquire um caráter especial pois está entre os principais problemas de saúde pública em todo o mundo. O traumatismo dentário pode ocasionar perdas dentárias irreparáveis em alguns casos, tanto no momento do acidente como no decorrer do tratamento ou até no futuro. Assim, esta condição pode gerar sérios danos psicológicos, sociais além de produzir custos significativos para o paciente. Uma abordagem de tratamento adequado permite um prognóstico favorável a longo prazo e prevenção evita o aumento do número de lesões. Introduction: Epidemiological studies show that dental trauma is a significant problem in young people between the ages of 8-15 years and its incidence in certain age groups even exceeds tooth decay and periodontal incidence disease. Thus, dental trauma is revealed as a public health problem, in which its increase is mainly due to traffic accidents, practice of extreme sports and even domestic violence. Of the most evident etiologic factors include the lip projection and increased overjet. Objective: It is intended to perform a bibliographic review addressing the diverse dental trauma, acquiring not only knowledge about the etiology, prevalence, relation to gender and age, as well as associated factors, emergency and ongoing treatment plans, possible complications, prognosis and prevention. Materials and Methods: A research was made in two databases of relevant literature concerning the proposed subject with time restriction of the last seven years (2007-2014) and the keywords "dental trauma", "tooth injuries", "permanent teeth", "prevalence" "tooth avulsion", "extreme sports", "treatment", "aesthetic", "primary care", "urgent care", in electronic databases such as Medline, PubMed, SciELO and B-on. The research was completed with specialty books in the Library of the Faculty of Health Sciences, Fernando Pessoa University and sites of national and international of health reputation. Conclusions: The dental trauma, to be considered a major public health problem, acquires a special importance. It can cause irreversible dental losses in some cases, both during the accident, as in the course of treatment, or even in the future. Thus, this condition can cause serious aesthetic, functional, psychological and social damages, in addition to producing significant cost to the patient. An approach with a proper treatment allows a more favorable long-term prognosis; but also emphasizes the importance of effective prevention, to avoid increasing the number of dental traumatic injuries.

Full textAbstract:
This study explored the psychological and sociological motivations of adult female and male obstacle course racers. A qualitative case study approach was used to explore the views, experiences, and motivations of obstacle course racing (OCR) participants. Descriptive statistics and cross tabulation was used to interpret responses to the 297 online questionnaires. A content analysis approach was used to analyze the qualitative data gathered from three focus groups with a total of 20 obstacle course racers. Three theories formed the basis of the study: Self-Determination Theory (SDT), Achievement Goal Theory (AGT), and Social Leaning Theory (SLT). Overall, findings supported previous research regarding motivations to participate in adventure racing and extreme sports. Individuals were guided more by intrinsic motives than extrinsic motives. Important motivations for obstacle course racers included the camaraderie among participants, connecting and socializing with other like-minded people, having fun, and having a physical challenge that allowed them to progress and keep on track with their health goals. Obstacle course racing was perceived as positively impacting participants’ health, mental wellness and their confidence in their physical abilities as well as in other areas of their lives. Findings from this study may inform future interventions to increase participation in OCR or to increase overall physical activity among adults by building on camaraderie, social connection, enjoyment, and self-efficacy.

Sujet médiatique récent, le phénomène des changements climatiques est devenu en ce début de XXIe siècle une préoccupation récurrente. Nous nous sommes alors interrogés non pas sur les mécanismes de ces dérèglements et les modélisations de leurs manifestations mais sur leurs représentations sociales auprès des acteurs touristiques territorialisés et travaillant dans un domaine soumis à l'aléa climatique : les sports d'hiver. Nous avons voulu connaître ainsi de quelle manière se traduisent sur un territoire donné et pour une activité ciblée les connaissances scientifiques actuelles en lien avec les changements climatiques. Au travers des méthodes d'enquête et d'analyse utilisées en psychologie sociale et en sociologie, que la géographie s'est appropriées, nous avons identifié les représentations sociales de la clientèle et des opérateurs touristiques des stations de sports d'hiver des Pyrénées-Orientales. Nous avons également identifié les comportements et les stratégies managériales induits par ces représentations.

Full textAbstract:
”Longboards” är ett examensarbete utfört av Leo Ekbom och Sammy-Sebastian Tawakkoli för innovations- och designingejörsprogrammet vid fakulteten för teknik och naturvetenskap på Karlstads Universitet. Uppdragsgivaren är Space Production AB, projektägare är Dan Edanius, art director och projektledare på företaget. Ett av företagets projekt var våren 2008 att producera Slalom Skateboarding VM och med anknytning till detta växte ett examensarbete fram.
Space Production AB började som ett montersnickeri men har idag utvecklats till ett företag som driver fullständiga utställnings- och eventprojekt. Företaget tillhandahåller allt från idéskiss till montering och servning även då huvudsysslan ligger i att producera, installera och lagra utformning från annan part.
Uppgiften var att ta fram en produktserie innehållande tre modeller av longbaords med bred spridning. Produkterna skulle vara unika och nischade men ändå säljbara och tillhöra ett övre segment av marknaden. Därtill gavs lite friare händer i att ta fram en rad vilda koncept som idébank för senare projekt.
Genom en djupgående researchfas, där information rörande materialkunskap, marknad, målgrupper och kultur, mynnade projektet ut i en kreativ designprocess. Målgruppsanalysen lade grunden till en rad referenskunder vars behov inspirerade och analyserades. Två skilda idegenereringstillfällen lade grunden till en kategorisering där åtta starka koncept presenterades för en sammansatt styrgrupp.
Arbetet resulterade i tre längre utvecklade koncept vilka har potential att bredda den befintliga marknaden för longboard försäljning samt en idébank för framtida utveckling av produkter.
”Longboards” is a degree project in the Innovations- and design engineering program at Karlstad University. The job requestor is Space Production AB with Dan Edanius, Art director and senior project manager, as the project owner.
Space Production AB started out as a showcase carpentry company but has today evolved into a company that operates complete exhibitions and events. The company’s main business is to produce, install and store branded environments designed by another party but also supplies everything from idea sketches to assemblage and service. One of Space projects spring 2008 was the production of Slalom Skateboarding World Championships and it was through this a degree project was created.
The task was to create a diverse product line containing three models of longboards. The products would be unique and aimed at a niche market but yet be sellable and appeal to the upper segment buyer. Further the opportunity to create more wild concepts that could be used in future projects was given.
An extensive research on materials, market, target group and culture, resulted in a creative design process. Through a target group analysis a number of reference consumers were created. Their needs worked as inspiration and was analysed. Two separate sessions of idea generating were the fundament of a categorization that eventually resulted in eight strong concepts that was presented to the management group.
The project has resulted in three developed concepts that could potentially broaden the existing longboard market as well as a band of ideas that could be used for inspiration of future projects.

A análise da concentração de metabólitos no sangue pode refletir o comportamento metabólico durante o exercício físico. O presente estudo teve por objetivo analisar o comportamento eletroquímico e do distúrbio ácido-básico de praticantes de Parkour, durante a realização de um percurso que utilizou movimentos fundamentais desta modalidade. Foram avaliados 23 praticantes de Parkour do sexo masculino, com idade média de 21,4±2,7 anos, com no mínimo dois anos de experiência na modalidade. Foram realizadas cinco coletas de sangue capilar da polpa digital dos dedos da mão, em diferentes momentos: (1) repouso, (2) após aquecimento, (3) logo após o esforço, (4) após cinco minutos e (5) após dez minutos. Foi realizado um percurso usando movimentos fundamentais da modalidade para caracterizar o esforço. A amostra foi analisada utilizando o aparelho de gasometria GEM Premier 3000, utilizando os parâmetros pH, Na+, K+, pH, lactato e HCO3−. Os valores de pH, lactato e HCO3− apresentaram diferença significativa (p<0,05) na maioria dos momentos analisados. Os valores de Ca2+, Na+, K+ apresentaram diferença significativa após o esforço, e uma rápida recuperação após cinco e dez minutos, quando comparados com os valores de referência. Os resultados obtidos demonstraram uma adaptação fisiológica dos eletrólitos, com rápida recuperação aos valores de referência. As alterações dos valores do pH, lactato e HCO3− identificam a utilização de vias anaeróbias para a produção de energia, assim como uma evidente acidose metabólica após o esforço. Os valores obtidos são similares a atletas de alto rendimento, principalmente de modalidades de força e velocidade. O presente estudo contribuiu para o entendimento do comportamento eletroquímico e do equilíbrio ácido-básico da modalidade Parkour, preenchendo assim uma lacuna na literatura.The analysis of the blood metabolites can show the metabolic behavior during physical exercises. This study aimed to analyze the electrochemical and acid base disorders behavior in Parkour athlets, during an exercise routine that used basic movements of this particular sport. Twenty three male athletes (average of 21,4±2,7 years old) with a minimum of two years of experience in Parkour were evaluated. The capillary blood was collected through the fingers in five diferent moments: (1) rest, (2) after warm-up, (3) after exercise, (4) five minutes later and (5) ten minutes later. A course using basic Parkour movements was used as reference. The samples were analyzed by the gasometric equipment GEM Premier 3000. The variables pH, sodium (Na+), potassium (K+), calcium (Ca2+), lactate and bicarbonate (HCO3−) were used. The pH, lactate and HCO3− showed significant variation (p<0,05) in most of the analyzed moments. Ca2+, Na+ and K+ values showed significant difference right after the exercise and a fast recovery after five and ten minutes when compared to the reference values. Results showed a physiological adaptation of electrolytes with a fast recovery back to the reference values. The values of pH, lactate e HCO3− present an anaerobic system usage, as well as a clear metabolic acidosis post exercise. The values obtained in this study are similar to high performance athletes values, mostly in strength and speed modalities. This study contributes to the understanding of the eletrochemical and acid-basic disorders behavior of Parkour athletes, filling a gap in the literature.

Full textAbstract:
La problématique de la performance des marins en navigation extrême, n’a été que très peu étudiée avec des méthodes scientifiques rigoureuses de façon systématique et sous un angle de vue global en conditions écologiques. Nos travaux se sont attachés à évaluer le comportement humain en conditions écologiques avec une approche environnementaliste et transactionnelle. L’objectif principal de cette thèse a été de comprendre quel est l’impact des facteurs environnementaux tels que la force du vent et la quantité de sommeil ainsi que d’une stimulation cognitive à l’aide d’un vidéo self-modeling sur la perception de l’anxiété, de la fatigue et la tolérance à l’effort à vitesse maximale aérobie. Les résultats de la première étude, en condition écologique, où l’influence du vent et de la privation du sommeil ont été modélisées grâce à l’outil des fonctions transferts, a permis de comprendre que le marin opère une régulation liée temporellement à son engagement et aux efforts ou privations comme par exemple celle du sommeil. Cette régulation est liée à la perception de l’anxiété et l’intensité de l’effort perçu et est influencée par les facteurs environnementaux comme le vent ou la privation de sommeil. Cette étude a aussi montré qu’il existe une relation entre la durée de l’engagement, mesurée par le nombre de jours passés en mer, et la quantité de sommeil nécessaire, permettant ainsi de résister aux conditions environnementales. Une seconde étude en milieu extrême, cette fois en équipage de deux personnes, en utilisant le même protocole a confirmé que la quantité de sommeil était le meilleur activateur pouvant agir sur l’anxiété et permettre au mieux sa régulation. Une troisième étude nous a permis de montrer que la tolérance à un effort, mesuré par la perception de l’effort, n’était pas couplée exclusivement à une réponse physiologique mais aussi à des facteurs cognitifs. Le résultat principal de cette étude pilote a été de montrer que l’utilisation du feedback vidéo comme stimulation cognitive diminue significativement la perception de l’effort à partir 50% de la durée de l’épreuve. Contrairement à ce qui aurait pu être attendu, aucun effet n’a été observé sur la fréquence cardiaque. L’ensemble de ces résultats tend à montrer l’importance de l’interaction environnement – individu en milieu extrême, ainsi que lors d’une épreuve menée jusqu’aux limites de l’épuisement. Ces résultats ouvrent des perspectives intéressantes dans les domaines de l’entraînement sportif et de la rééducationThe problem of performance in extreme sailing navigation has been very little studied using rigorous scientific methods consistently and at an angle of view in global environmental conditions. Our work sought to evaluate human behavior in ecological conditions with environmentalist and transactional approach. The main objective of this thesis was to understand what the impact of environmental factors such as wind strength and the amount of sleep as well as cognitive stimulation using a video self-modeling on perception of anxiety, fatigue and exercise tolerance in maximal aerobic speed. The results of the first study, ecological condition, where the influence of wind and sleep deprivation were modeled using the tool transfers functions, has to understand that the sailor makes a time- dependent regulation of its commitment and efforts and hardships such as that of sleep. This regulation is related to the perception of anxiety and intensity of perceived fatigue and is influenced by environmental factors such as wind or sleep deprivation. This study also showed that there is a relationship between the duration of the engagement, as measured by the number of days at sea, and the amount of sleep needed, allowing withstand environmental conditions. A second study in extreme conditions, this time with a crew of two people using the same protocol confirmed that the amount of sleep was the best activator can act on anxiety and allow its better regulation. A third study, we showed that the tolerance to stress, as measured by perceived exertion, was not exclusively coupled to a physiological response but also cognitive factors. The main result of this pilot study was to show that the use of video feedback as cognitive stimulation significantly reduces the perception of effort from 50 % of the duration of the event. Contrary to what might be expected, no effect was observed on heart rate. All of these results suggest the importance of the interaction environment - individual in extreme environments, and in a test conducted to the limits of exhaustion. These results open interesting perspectives in the fields of sports training and rehabilitation

Full textAbstract:
L'objectif était de développer un outil individuel de management de la fatigue. Cet outil, dénommé Scextan®, a été conçu sous la forme d'une application informatique. Pour cela, plusieurs étapes de développement et de validation ont été franchies. Dans un premier temps, nous avons choisi d'observer le sommeil des navigateurs à la voile en solitaire qui doivent gérer une forte privation de sommeil. Les résultats ont montré que ces marins sont soumis aux mêmes principes de régulation de sommeil que l'adulte sain. Nous avons retenu ces sujets comme population expérimentale. Dans un deuxième temps, nous avons validé le logiciel Scextan® pour la mesure du rythme veille-sommeil qui s'est révélée plus précise qu'avec un agenda de sommeil manuscrit. Puis, nous avons évalué la pertinence de l'implémentation d'un modèle de prédiction mathématique de performances dans Scextan®. Chez des marins en course, le modèle a su prédire 70% de la variance des mesures. Dans un dernier temps, Scextan® a été proposé aux skippers de la course transatlantique "Route du Rhum". Seul le vainqueur de la course a utilisé de façon quasi systématique le logiciel Scextan® pour gérer son état de forme. L'agenda de Sommeil Interactif Scextan® est toujours en cours de développement, mais a déjà démontré qu'il pouvait être un outil de recherche à part entière, et qu'il tendrait rapidement à devenir un outil pédagogiqueThe goal of the thesis was to develop an individual fatigue management tool called Scextan® and designed as a software application. The development of this system involved several research and validation steps. We first describe sleep patterns of single-handed sailors, who have to manage severe sleep deprivation. Results suggested that single-handed sailors are subject to the same principles of sleep regulation as healthy adults and we choose these subjects as our mains test population. In a second step, we developed and validated the Scextan® software application. Results revealed that Scextan® is more accurate than a paper-based sleep diary. The third study was to measure fatigue in single-handed ocean race and compare the results with a mathematical prediction model of performances, which was able to predict 67% of the measured fatigue. Lastly, skippers of the 2010 "Route du Rhum" single-handed transatlantic race were offered use of Scextan®. The race winner was the only sailor to use it intensively to manage and rationallyanticipate his state of alertness. Although Scextan® is still being improved, it has already proved itself to be a valuable research tool and is on the way to becoming an individual management tool

The Swedish government’s objective regarding information technology is to be world-leading in using the possibilities that digitization provides. In some aspects this has already been done, but in some areas much is yet to be accomplished. Although sports and recreational fitness activities are amongst the fastest growing areas of personal and consumer-oriented cloud computing-based technologies around the globe, there are areas within the genre that’s not evolving as quickly. In Sweden, football is the biggest sport but it lacks in the use of technology. Related research shows that usable technology exists, but the using of it is hampered by its accessibility. Meanwhile, Urban Computing is an growing, interdisciplinary field which pertains to the study and application of computing technology in urban areas. This made us raise the question whether the technology used in Urban Computing can influence the field of Sport-IT and provide valuable insight in designing the next generation football coaching tool. The purpose of this study is therefore to examine the outcome of integrating IT-solutions from Urban Computing into environments suited for team sports and combining them with the individualized technologies that already exists in Sport-IT. We also explore what technology requirements football coaches have and how the weather and the climate effects designing the next generation coaching tool. The result of the study indicates that the needs of football coaches, as of today, is not met and that Urban Computing very well may influence the development of the next generation coaching tool.

Full textAbstract:
Véritable phénomène de société, le mixed martial arts ou MMA est l'un des sports qui connaît actuellement le plus grand essor. Dans la traduction française, le terme d'arts martiaux mixtes revient fréquemment. Sport contemporain par excellence, le MMA est né et s'est développé au cours du XXème siècle où il est resté très marginalisé, pour connaître son aspect formalisé et médiatisé seulement dans les années 1990. Cette discipline qui a connu un processus de sportivisation inversée, est marquée par une réception difficile de la part des autorités, des fédérations sportives olympiques et de l'opinion publique : la cage qui accueille les combats, le sang et les frappes sur un homme au sol posent des problèmes d'acceptation. Ces éléments négatifs se retrouvent dans les représentations sociales et individuelles, chez les réponses des enquêtés qu'ils soient initiés ou non-initiés aux pratiques de combat hybride. En France, la compétition de MMA n'est pas autorisée alors que les clubs l'enseignent auprès de pratiquants de plus en plus nombreux. Les arts martiaux mixtes réunissent les contraires : une altérité fondée sur l'utilisation de l'agression instrumentale potentiellement destructrice, une réciprocité violente, mais socialisatrice et un sport « viril » capitaliste qui se nourrit du libéralisme et du débridement du pouvoir étatique. Pris dans un contexte post-moral, l'extériorisation d'une violence dans le MMA est à contre-courant du processus de pacification que la société connaît, associé à la quête de sécurité. Enfin, l'engagement corporel intense de ce sport ne correspond pas au culte du corps en bonne santé qui prédomine désormais. De ce fait, cette discipline questionne sur la place des sports-spectacles violents au sein d'une société pacifiéeNowadays MMA is truly a phenomenon of society, it is among the fastest-growing sports of our time. The French translation frequently uses the words: arts martiaux mixtes. Contemporary sport par excellence, MMA was born and expanded during the late 20th century where it remained very marginalized. Its expansion came in the 1990s thanks to media coverage. This sport experienced an inversed process of sportivization. It is characterized by a hesitant reception from authorities, Olympic sport federations and public opinion: the cage, blood and hitting a grounded opponent pose problems for many observers. These negative aspects may be found in the social and individual representations in the answers of surveyed individuals, both initiated and non-initiated to hybrid combat sports. Mixed Martial Arts competition is not allowed in France, while athletes are more and more numerous within French MMA academies and gyms. This sport combines opposing concepts: otherness based on the utilization of instrumental, potentially destructive aggression, a violent but socializing reciprocity and a manly, capitalist sport which is based on liberalism and a stripping of state power. Taken in a post-moral context, the violence acts out against the process of pacification. This process is associated with a search for security and peace. Finally, the intensive bodily engagement of MMA does not correspond with the healthy body cult which predominates nowadays. Therefore, this practice questions the role of sport entertainment within a peaceful society

Full textAbstract:
Dans les métiers de l'investissement financier, le risque est un outil de travail quotidien et reconnu. Tout individu est ainsi amené à déterminer quels risques valent la peine d'être pris, ou quelle perte vaut la peine d'être risquée. Plus le risque pris est important, plus grands seront les bénéfices - ou pertes - encourus. Ces caractéristiques, le monde de l'investissement financier les partage avec les sports à hauts risques, ou sports extrêmes. Malgré cette similitude, la littérature scientifique issue de chacun des ces domaines adopte une perspective qui lui est propre afin d'expliquer le risque et la prise de risques. Alors que la recherche en finance s'attarde avant tout à la quantification des risques, la littérature sportive s'intéresse davantage à la personnalité des pratiquants de sports extrêmes, répondant donc aux questions : Qui prend des risques ? Pourquoi ? De récentes études ont avancé que les traits de personnalité du narcissisme et de l'alexithymie contribuent significativement à expliquer la tendance à la prise de risques dans le sport. Par le biais de six études successives et complémentaires, ce travail de thèse a pour objectif d'élargir ces résultats par la mise en évidence des relations entre les traits narcissiques et alexithymiques, et la prise de risques financiers

Full textAbstract:
Gender is a constantly debated subject, especially within the world of sports. The representation of athletes in the media is dominated by the males. It is often that the athletes are portrayed on the basis of their sex and gender. With the extreme skiing being a new and modern sport, should it not be autonomous from gender? This study aims to examine whether and if so how the cover design differ between female and male extreme skiing athletes and how it affects the professional skiers. A semiotic analysis was used on the covers of the Swedish skier’s magazine Åka Skidor and interviews were held with some of Sweden’s professional extreme skiers using a hermeneutic approach. The theoretical framework used for this study was poststructuralism, poststructuralist feminism and gender theory. The semiotic analysis showed that there is in fact a difference in both representation and how the skiers are portrayed on the covers of Åka Skidor. The interviews that were held resulted in three themes to answer the aim of this study. They were; the climate of extreme skiing, extreme skiing in media and the future of extreme skiing. The skiers had acknowledged that there is a difference between females and males when it comes to media representation and how they are portrayed. Although the explanation for this differs between the skiers they all mentioned the power of sponsors and sponsorship. However; the issue with athletes being portrayed and represented different based on their gender is not important enough to debate within the world of extreme skiing today. Therefore, it can be concluded that extreme skiing will probably not be autonomous from gender in the near future.

Full textAbstract:
Notre recherche consiste à identifier les déterminants psychobiologiques et émotionnels des activités physiques à risque : rallye, lifestyle sport, équitation et cirque (N= 507). Nous avons comparé le tempérament et le caractère de jeunes cavaliers et golfeurs en Tunisie et en France. Ensuite, nous avons comparé la dominance télique en fonction de différents sports. Nous avons aussi testé les variations des états émotionnels, la dimension névrosisme et les variables fuite et alexithymie en lien avec l’imprudence et la prise de risque. Enfin, nous avons identifié le profil de personnalité, et plus précisément la dominance télique et la recherche de sensations ainsi que le stress perçu, de circassiens. Nous avons suivi l’évolution du taux du cortisol pendant l’entrainement et le spectacle. Les résultats montrent que les cavaliers et les golfeurs ont un score élevé sur les dimensions persistance et évitement du danger. Les sports mécaniques seraient plus risqués que les lifestyle sports. Le rallye permettrait à ses adeptes de diminuer leurs affects négatifs. Le névrosisme et l’alexithymie contribuent à l’adoption de comportements imprudents et de prise de risque. Les circassiens étudiés sont tous paratéliques, chercheurs de sensations, et perçoivent peu le stress ; leur niveau de cortisol est plus élevé le jour du spectacle que lors de l’entrainement. Ainsi, nous avons pu identifier les différences individuelles qui favoriseraient l’engagement dans certaines activités physiques à risque, tout en relevant le rôle des variables motivationnelles, émotionnelles, biologiques, ainsi que les facteurs de personnalité dans la compréhension d’un tel engagementRisk-taking behaviors constitute a growing domain, yet not well known. Our research’s goal aimed at identifying the psychobiological and emotional determinants of risky physical activities: rally, lifestyle sports, horse riding, golf players and circus artists (N = 507). We compared the temperament and character of young horse riders and young golfers, both in Tunisia and in France. We then compared the telic dominance of participants in different kinds of sports. We also tested changes in emotional states, neuroticism, escape and alexithymia related to risk-taking. Finally, we identified the personality profiles, specifically the telic dominance and sensation seeking and the perceived stress among circus artists. We have followed the evolution of their cortisol level while training and during a show. The results show that the horse riders and golfers have a high score on persistence and harm avoidance. Motor sports imply more risk-taking than lifestyle sports. The rally context allows its followers to decrease their level of negative affect, neuroticism and alexithymia, which contributes to the adoption of reckless behaviors. Circus artists are paratelic, sensation seekers, and perceive a low level of stress; their cortisol level is higher during the show than on a training day. Overall, we could identify the individual differences that would promote involvement in physical activities at risk, while noting the role of motivational, emotional, biological variables and personality factors in the understanding of such a commitment

Man has always in one way or another had to take risks in order to survive, but in today's society, voluntary risks increased markedly. It is about both physical and financial risks. The aim of this essay is to problematize what it is for properties that drive people to extreme sports and adventure travel. We want to see how extreme sports performers own picture looks compared to how the media presents them. We have in this essay interviewed two long sailors, a BASE jumper and an ex-mountain climber to see how the performers own picture of reality looks. We examined how the media presents different extreme sports in the form of news magazines and lifestyle magazine. We have concluded that there is a huge gap between the self images of their sport compared to how the media presents them. News Magazines often deals with risks and dangers of extreme sports and put them in different contexts in their articles and that the sport is to demonstrate its capacity, to reach goals, triumph and prestige. Also Sunday supplement that are not news-oriented have the same main focus. Lifestyle magazines image of extreme sports performers is more consistent with the addition to the participants own image in which the actual experience and lifestyle is important and not the risk-seeking.

Participants were 15 professional sailors, ranging in age from 23-49 years (M age = 35.9 years; SD = 7.4), who competed in the 2005/06 VOR. After receiving approval from the Temple University Institutional Review Board, the researcher recruited participants who were subsequently required to provide informed consent to participate in the study. Using a semi-structured interview format, face-to-face interviews were completed with three sailors in Miami, FL, and with nine sailors in Valencia, Spain (three interviews with individual participants, one interview with two participants, and a focus group with four participants). Three interviews were completed via telephone. All interviews were transcribed verbatim. Each transcript was then analysed through an inductive open coding process. Data analysis revealed nine major themes (Background, Skiffs on Steroids, Boat Breakdowns, Managing Self, Pressure, Tragedy, Extreme, Team, and Reflecting) with associated subthemes, and three dimensions (Resonance, Edgework, and Performance Capacities) with associated subdimensions. A framework for understanding the experiences of the sailors was conceived in the form of a model depicting the dimensions of resonance (a passion for adventure and the VOR in particular), edgework (a desire and ability to perform in high-risk, life threatening situations), and performance capacities (team, individual, and boat). The model suggests an interplay between the dimensions of edgework and resonance, against which is set the performance dimension. This study is the first to take a glimpse inside the experiences of professional ocean racing sailors who compete in fully crewed around-the-world races. Findings confirm the widely held belief that the VOR is an extreme and unique event in the world of sport.

Full textAbstract:
The full exploitation of bacterial whole-cell biosensing systems in field applications requires the survival of bacterial cells and long term-preservation of their sensing ability during transportation and on-site storage of such analytical systems. Specifically, there is a need for rapid, simple and inexpensive biosensing systems for monitoring human health and the environment in remote areas which often suffer from harsh atmospheric conditions and inadequate commercial distribution and storage facilities. Our laboratory has previously reported the successful use of bacterial spores as vehicles for the long-term preservation and storage of whole-cell biosensing systems at room temperature.
In the present research, we have accomplished a year-long study to investigate the effect of extreme climatic conditions on the stability of spores-based whole-cell biosensing systems. The spores were stored in laboratory conditions that simulated those found in real harsh environments and germination ability and analytical performance of the spore-based sensing systems upon storage in such conditions was monitored. Our results proved that the intrinsic resistance of spores to harsh environmental conditions helped maintain the integrity of the sensor bacteria. The revived active cells actually retained their analytical performance during the course of the twelve-month storage study.

Full textAbstract:
Sammanfattning Syfte och frågeställningar Det övergripande syftet med studien är att undersöka hur brottare upplever bantning. Studien kommer att undersöka seniorbrottare och genomföras i Stockholm. Följande frågeställningar är i fokus vid denna studie: Hur upplever brottare i studien att bantningsprocessen kommer att påverkas av det nya invägningssystemet? Hur upplever brottare i studien att det nya invägningssystemet påverkar deras inställning inför bantning? Metod I denna studie kommer vi att använda oss av den kvalitativa metoden hermeneutik. Eftersom studien följer en hermeneutisk ansats och har som mål att skapa förståelse av upplevelser är det fördelaktigt med intervjuer då vi kan få djupare svar. Intervjuerna utformades utifrån en semistrukturerad mall. Urvalet var strategiskt och bestod av sex seniorbrottare i Stockholm. Analysmetoden grundar sig i ett hermeneutiskt förhållningssätt till vår data. Resultat Sammanfattningsvis visar resultaten att brottarna i studien upplever att bantningsprocessen inte kommer att påverkas av det nya invägningssystemet vad gäller förekomsten av bantning, bantningsmetoderna och bantningsprocessen. Däremot upplever brottarna att det nya invägningssystemet har påverkat hur stor andel av sin kroppsvikt brottarna kan banta. Resultaten tyder även på att brottarna överlag har blivit mer negativt inställda inför bantning efter införandet av det nya invägningssystemet. Slutsats Brottarna i studien upplever att bantningsprocessen inte kommer att påverkas av det nya invägningssystemet vilket verkar bero på att bantning är djupt inrotad i brottningskulturen. Däremot verkar det nya invägningssystemet leda till att brottare kommer banta en mindre andel av sin kroppsvikt, vilket främst beror på den minskade återhämtningstiden mellan invägning och tävling. Det nya invägningssystemet verkar dessutom ha påverkat brottares inställning inför bantning. Flera brottare upplever att de nya reglerna gör att bantningsprocessen har blivit psykiskt jobbigare och mer ohälsosam.Specialidrott, LS4A

Full textAbstract:
Défier ou jouer avec la gravité, explorer les profondeurs et mettre sa résistance ou plus simplement son corps à l’épreuve, se mesurer aux éléments naturels en fréquentant des milieux a priori hostiles : autant de formes d’exposition sportive au danger qui fascinent et intriguent à la fois. Ce travail est une exploration des processus d’engagement et de désengagement corporel, envisagés sous leurs aspects épistémiques et empiriques. Deux grandes questions jalonnent ainsi cette analyse : 1) comment concevoir l’engagement corporel, à travers le dialogue et la complémentarité entre schèmes d'intelligibilité ; 2) plus concrètement, comment devient-on pratiquant de telles activités, et pourquoi, un jour, décide-t-on de « raccrocher » ?L’analyse d’une trentaine de récits de sportifs engagés dans des activités de nature « à risque » met en lumière les dynamiques des processus d’engagement, de maintien et de désengagement. Ainsi, si s’engager est rarement le fruit du hasard, il n’est pas davantage celui d’une pure réflexivité. Parfois, l’engagement naît d’expériences et de rencontres imprévisibles. Ce travail conforte par ailleurs les résultats de nombreuses études consacrées aux motivations de ces pratiquants : recherche de sensations, d’autonomie, de performance, émulation subculturelle, etc. Elle s’en distingue cependant en montrant comment ces motifs d’engagement, loin de s’opposer, s’articulent et se complètent de manière systématique. Enfin, après avoir souligné la place cruciale, aux yeux des interviewés, de l’autonomie et de la responsabilité, érigées au rang de véritable éthique, nous montrons à quel point se désengager est chose difficile. Raccrocher tient d’un processus vécu différemment selon qu’il a ou non été préparé.Comprendre l'engagement corporel requiert finalement un élargissement du regard au corps, à la culture, au risque et à la sécurité, à l’autonomie, et plus largement à la responsabilité. L’engagement corporel constitue ainsi un support en parfaite adéquation avec son époque : il mêle, combine et parfois oppose des dynamiques identitaires portées par des dispositions, la réflexivité et les affectsDefy or play with gravity, exploring the depths and bring their stamina or just their body, compete with the natural elements by frequenting, a priori, hostile environments: as many forms of sport exposure to danger that intrigue and fascinate at a time. This work is an exploration of the process of corporal engagement and disengagement, considered in their epistemic and empirical aspects. Two main questions mark this analysis: 1) how to conceive the corporal engagement in its complexity, through dialogue and complementary patterns of intelligibility; 2) more specifically, how do they become engaged in such activities, and why, suddenly, they decide to “hang up”?The analysis of thirty stories of sportsmen engaged in "at-risk" nature activities highlights the dynamic process of engagement, retention and disengagement. Thus, if commitment is rarely the result of chance, it is more than a mere reflexivity. Sometimes the commitment is born from experiences and unpredictable encounters. This work also confirms the results of many motivations studies of practitioners: search of sensation, autonomy, performance, subcultural emulation, etc. However, it differs from showing how these patterns of engagement, far from opposing, they are articulated and completed in a systematic way. Finally, after stressing the crucial role, in the eyes of the respondents, of the autonomy and the responsibility set up as true ethics, we show how difficult is to disengage. To hang up is a process experienced differently depending on whether the sportsman was prepared or not.To understand physical engagement requires a final enlargement as regards body, culture, risk and security, autonomy, and from a broader perspective, responsibility. Therefore, the body engagement constitutes a support in perfect harmony with its time: it mixes, combines, and sometimes objects the dynamics of identity induced by capacities, reflexivity and emotions

Penin, Nicolas. "Le goût du risque : modes d'engagement et rapports sociaux de sexe dans les pratiques sportives à risque." Paris 11, 2005. http://www.theses.fr/2005PA113001.
Full textAbstract:
Les pratiques sportives à risque cultivent les paradoxes. D’abord parce qu’elles semblent être en totale contradiction avec la préoccupation sécuritaire des sociétés occidentales contemporaines. Ensuite parce qu’elles donnent à voir un déséquilibre entre ce qu’il y a à perdre et ce qu’il y a à gagner. Car dans ces sports, la vie est engagée. La « raison » peine donc à rendre intelligibles ces pratiques. L’engagement dans les sports à risque plus étonnant encore lorsqu’il est celui d’une femme. Beaucoup moins que les hommes, elles investissent ces terrains qui s’apparentent à de véritables « fiefs de la virilité » (Elias et Dunning, 1994). Et même lorsqu’hommes et femmes choisissent des disciplines communes, leurs trajectoires ne se confondent pas. Les modes de production de l’engagement des femmes dans les sports à risque ressemblent peu à ceux que connaissent les hommes. Pas plus d’ailleurs leurs modes de pratiques ne se superposent. En particulier, les prises de risque différencient nettement les façons de faire. Et non seulement le risque produit de la séparation mais il fonctionne également comme un principe classant qui hiérarchise. En ce sens, il façonne largement la production des rapports sociaux de sexe. Attaché à la virilité, le risque participe également à la production des hommes et du masculin ainsi qu’il contribue à asseoir et à légitimer ce qui se donne à voir comme la domination d’un sexe sur l’autre, la domination masculine. Mais cette domination n’est ni totale, ni naturelle, ni immuable. C’est une construction sociale, produite par la rencontre de deux groupes antagonistes. Dès lors les résistances existent et participent à la définition du genreExtreme sports are full of paradoxes. First of all, because they seem to be in contradiction with social preoccupation for security in western societies. Secondly, they show an imbalence between what people can win and what they can loose. In these sports, life is engaged. "Reason" has difficulty to give intelligibility to theses practices. Involvement in extreme sports is even more surprising, when it concerns women. Even less than men, they chose to practive these sports that are quite exclusively masculine. And even when men and women choose the same discipline, their paths are quite differents. The way they practice are not more similars. Particularly, risk taking is generaly different between men and women. And risk not only differentiates men's and women's manners, it also produces a gender hierarchy. That's why we can say that risk shapes the relations between men and women. Attached to masculinity, risk takes part to "males's production" and contributes to build male's domination. But this domination is neither total, nor natural, nor unchanging. It's a social construction, produced by the meeting of two antagonistic groups. Consequently resistances exist and participate to the definition of gender

Full textAbstract:
L'objectif était de développer un outil individuel de management de la fatigue. Cet outil, dénommé Scextan®, a été conçu sous la forme d'une application informatique. Pour cela, plusieurs étapes de développement et de validation ont été franchies. Dans un premier temps, nous avons choisi d'observer le sommeil des navigateurs à la voile en solitaire qui doivent gérer une forte privation de sommeil. Les résultats ont montré que ces marins sont soumis aux mêmes principes de régulation de sommeil que l'adulte sain. Nous avons retenu ces sujets comme population expérimentale. Dans un deuxième temps, nous avons validé le logiciel Scextan® pour la mesure du rythme veille-sommeil qui s'est révélée plus précise qu'avec un agenda de sommeil manuscrit. Puis, nous avons évalué la pertinence de l'implémentation d'un modèle de prédiction mathématique de performances dans Scextan®. Chez des marins en course, le modèle a su prédire 70% de la variance des mesures. Dans un dernier temps, Scextan® a été proposé aux skippers de la course transatlantique "Route du Rhum". Seul le vainqueur de la course a utilisé de façon quasi systématique le logiciel Scextan® pour gérer son état de forme. L'agenda de Sommeil Interactif Scextan® est toujours en cours de développement, mais a déjà démontré qu'il pouvait être un outil de recherche à part entière, et qu'il tendrait rapidement à devenir un outil pédagogique.
