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.

Nutritional intervention program in elite athletes: single case design research with one professional basketball player

The American College of Sports Medicine argues that sports performance is improved with optimal nutrition (ACSM position stand, MSSE 2009, Mar; 41(3):709-31). However, scientific evidence shows that professional athletes do not achieve nutritional recommendations (Farajian et al, IJSNEM 2004 Oct; 14(5):574-85; Shroeder et al EJSS 2004 Jun 4 (2):1; Nogueira & Da Costa, IJSNEM 2004; 14:684-697) Objectives: a) describe the nutritional practices of one professional basketball player b) carry out a long term nutritional intervention to adapt his diet to current recommendations.

Wearing Eye Tracking Technology During Batting Practice: Assessing the Experiences of Professional Baseball Athletes

Utilizing wearable technology in sport allows for the collection of motor behavior data during task engagement. This data can be assessed in real-time or retrospectively. Although enriching the scope of performance data, the consequences of wearable technology on the athlete-user, specifically the cognitive effects, has not been fully investigated, hence the purpose of this study. This qualitative study examines the cognitions of 57 professional baseball players who wore eye tracking technology whilst engaged in batting practice. Their verbal self-reports were framed by temporal context: before-during-after task. Three themes emerged during the pre-task segment: social appearance anxiety, claimed self-handicapping, and curiosity. During the task of batting, verbal behavior contained motivational and instructional overt self-talk while claimed self-handicapping was sustained. The final, post-performance segment was marked by the re-emergence of curiosity from the pre-task period as well as self-evaluation/appraisal. Given the participants were professional athletes, their performance has greater career implications than amateur competitors. Nonetheless, the verbal behavior elicited while wearing eye tracking technology indicates an awareness of the equipment by the user. This study found cognitive effects from wearable technology; more research is required to under-stand the scope and nature of those effects on cognitive and motor behaviors.

The sources of stress experienced by professional Australian footballers

Previous studies looking at the sources of stress in sport have generally overlooked the unique experiences of professional athletes participating in team sports. This paper describes the results of a qualitative study aimed at identifying the sources of stress experienced by a cross-section of professional Australian footballers. Players from two Australian Football League clubs took part in the study involving in-depth, one-to-one interviews and focus group discussions. The results revealed that players identified sources of stress that went beyond those associated with the competitive event (such as poor performances) and included a lack of feedback, difficulty balancing football and study commitments, and job insecurity. The influence of both competition and non-competition sources of stress parallels previous research involving non-professional athletes and indicates that the entire sporting experience needs to be taken into account when developing stress management strategies.

Sports training, science and class among British amateur athletes in the mid to late nineteenth century

Organised amateur sports emerged in the second half of the nineteenth century. This paper, an exercise in historical sociology, analyses how a new system of sports training was devised by the amateurs to meet their particular needs. The data comes from contemporary British training manuals and the analysis is informed by the theories of Bourdieu and Foucault. That amateurs came from the higher social classes was highly
significant: it meant that they could not adopt existing training practices because these were associated with plebeian professional athletes. For amateurs to have followed the preparation of the professionals would have placed their bodies under the control of a social inferior and promoted a somatic shape more in keeping with the lower than with
the higher social orders. Mirroring the social distance between them, amateurs came to stridently reject professional training practices. Instead, they devised new training techniques which were justified through recourse to contemporary bio-medical knowledge. It is argued that amateur training originated for social reasons, with the proponents’ class positions and social capital facilitating the evocation of scientific knowledge as a legitimating ideology.

Train without strain : health and amateur athletes

An exercise in historical sociology, this paper investigates the association between training and health made by amateur athletes between about 1860 and WWI. It examines the idea that while exercise benefited a person’s health and well-being, excessive exertion caused potentially life-threatening ‘strain’. The paper sets out the interpretation of contemporary scientific knowledge about the body–which the author terms the ‘physiology of strain’–that underpinned the advice given to those undergoing a training program for amateur competition. The point is made that the imputed effects of exercise on health were deduced from this scientific knowledge; it did not derive from bio-medical investigations specifically addressing these issues. Amateur athletes included people drawn from the professionally educated elite and medical practitioners figured significantly among them. Using insights from Bourdieu and Foucault, it is argued that their social power and professional connections served to legitimate their interpretation of the physiological effects of exercise (denying the value of the training practices of working class professional athletes) and cemented the physiology of strain as a ‘factual’ statement about exercise and health until well into the twentieth century. The data for the paper comes from training manuals, medical journals and other contemporary publications.

Surveillance, Governance and Professional Sport

The surveillance capacities of professional sports clubs and Leagues are directly related to their modes of governance. This paper identifies how private sports clubs enact surveillance through processes of inclusion and exclusion. Using three examples to demonstrate these processes, we argue that the surveillance mechanisms associated with sports governance at times replicate, at other times contradict, and at other times influence those associated with broader law enforcement and security developments. These examples also suggest potential increases in surveillance activities that emerge in club governance often flow from external concerns regarding allegations of crime, national security breaches and corruption. These context-specific case studies (Flyvbjerg 2001) demonstrate how surveillance and identity authentication are closely tied to the complex, multi-tiered governance structures and practices in three distinct sports. We then explore how these patterns can be interpreted as either connected to or distinct from equivalent developments involving the surveillance surge (Murakami Wood 2009) and concepts of inclusion and exclusion under the criminal law. We conclude by discussing how both internal and external regulatory forces can shape interrelated facets of surveillance, governance and exclusion in elite sports.

Evolution of session RPE and fatigue during a long term nutritional intervention in one professional basketball player

Some evidence shows that the rate of perceived exertion of one session (RPE-S) and fatigue (Fat) of athletes can be decreased by the intake of carbohydrates (HCO) during exercise. However, it is well known that professional athletes do not meet nutritional recommendations (NR) but a long term nutritional intervention (NI) can improve their dietary intake (DI). What is not known is whether these long-term changes in DI can influence RPE-S and Fat of training. Our aim was to conduct a long term NI to adapt the DI of one professional basketball player to current NR and evaluate the influence of these changes on long-term RPE and Fat.

Urinary biomolecular indicators of exercise-induced over exertion injury

Poor health and injury represent major obstacles to the future economic security of Australia. The national economic cost of work-related injury is estimated at $57.5 billion p/a. Since exposure to high physical demands is a major risk factor for musculoskeletal injury, monitoring and managing such physical activity levels in workers is a potentially important injury prevention strategy. Current injury monitoring practices are inadequate for the provision of clinically valuable information about the tissue specific responses to physical exertion. Injury of various soft tissue structures can manifest over time through accumulation of micro-trauma. Such micro-trauma has a propensity to increase the risk of acute injuries to soft-tissue structures such as muscle or tendon. As such, the capacity to monitor biomarkers that result from the disruption of these tissues offers a means of assisting the pre-emptive management of subclinical injury prior to acute failure or for evaluation of recovery processes. Here we have adopted an in-vivo exercise induced muscle damage model allowing the application of laboratory controlled conditions to assist in uncovering biochemical indicators associated with soft-tissue trauma and recovery. Importantly, urine was utilised as the diagnostic medium since it is non-invasive to collect, more acceptable to workers and less costly to employers. Moreover, it is our hypothesis that exercise induced tissue degradation products enter the circulation and are subsequently filtered by the kidney and pass through to the urine. To test this hypothesis a range of metabolomic and proteomic discovery-phase techniques were used, along with targeted approaches. Several small molecules relating to tissue damage were identified along with a series of skeletal muscle-specific protein fragments resulting from exercise induced soft-tissue damage. Each of the potential biomolecular markers appeared to be temporally present within urine. Moreover, the regulation of abundance seemed to be associated with functional recovery following the injury. This discovery may have important clinical applications for monitoring of a variety of inflammatory myopathies as well as novel applications in monitoring of the musculoskeletal health status of workers, professional athletes and/or military personnel to reduce the onset of potentially debilitating musculoskeletal injuries within these professions.

Les effets d’une commotion cérébrale d’origine sportive sur le fonctionnement cognitif de l’enfant évalués à l’aide de potentiels évoqués cognitifs et de tests neuropsychologiques

Les commotions cérébrales d’origine sportive sont fréquentes chez les athlètes professionnels et semblent l’être tout autant chez les jeunes sportifs. Chez l’adulte, les symptômes se résorbent dans la majorité des cas assez rapidement (7-10 jours), mais la récupération peut s’avérer différente chez les jeunes. Plusieurs études utilisant les potentiels évoqués cognitifs ont découvert des anomalies cérébrales en l’absence de symptômes cliniques observables chez l'adulte. Toutefois, peu de données scientifiques sont disponibles sur les répercussions d’un tel impact sur le cerveau en développement. Le but de l’étude était de déterminer s’il existe une relation entre l’âge de survenue au moment de la commotion et la gravité des déficits. Cette étude transversale a évalué le fonctionnement cognitif de sportifs par des tests neuropsychologiques ainsi que les mécanismes neuronaux de l’orientation de l’attention (P3a) et de mise à jour de l’information en mémoire de travail (P3b) à l’aide de potentiels évoqués cognitifs. Les athlètes étaient répartis selon trois groupes d’âge [9-12 ans (n=32); 13-16 ans (n=34); adultes (n=30)], la moitié ayant subi une commotion dans la dernière année. Les comparaisons entre les groupes ont été effectuées par une série d’ANOVAs. Comparativement au groupe contrôle, les adolescents commotionnés présentaient des déficits de mémoire de travail. Les athlètes commotionnés démontraient une réduction de l’amplitude de la P3b comparativement aux non-commotionnés. Les résultats illustrent la présence de déficits neurophysiologiques persistants et ce, au moins six mois suivant l’impact. Les enfants semblent aussi sensibles que les adultes aux effets délétères d’une commotion cérébrale et les conséquences s’avèrent plus sévères chez l’adolescent.

Traumatisme craniocérébral, services de santé mentale et suicide de l'enfance à l'âge adulte : une étude épidémiologique et qualitative de la situation québécoise (1987 à 2013)

Introduction et recension des écrits : Récemment, les suicides de vétérans et d’athlètes professionnels ont attiré l’attention sur l’association entre le TCC et le suicide. Les lignes directrices concernant la prise en charge en santé mentale dans cette population demeurent fragmentaires. Les objectifs de cette thèse sont de 1) déterminer si une association existe entre le TCC subi dans l’enfance et le suicide futur, 2) explorer si les personnes qui se sont suicidées ont consulté un psychiatre dans l’année précédant le suicide et évaluer si cela diffère selon que la personne ait eu un TCC ou non, 3) décrire et qualifier l’offre québécoise de santé mentale offerte en réadaptation aux enfants et aux adultes ayant subi un TCC. Méthodologie : Le volet épidémiologique consiste en une étude de cohorte rétrospective sur un échantillon de 135 703 enfants ayant reçu des services médicaux au Québec en 1987 et suivis jusqu’en 2008. Le volet qualitatif comprend un sondage auprès des gestionnaires des programmes de réadaptation TCC du Québec, des groupes de discussion avec des cliniciens et des entrevues avec des survivants de TCC et leurs proches. Résultats : Notre étude épidémiologique confirme une association significative entre le TCC subi dans l’enfance (HR 1,49 IC95% 1,04- 2,14), dans l’adolescence (HR 1,57, IC 95% 1,09-2,26) et à l’âge adulte (HR 2,53, IC95% 1,79-3,59) et le suicide. Malgré un risque de suicide plus élevé, les personnes avec un TCC et qui se sont suicidées n’ont pas consulté de psychiatre plus fréquemment que les personnes sans TCC (OR 1,29, IC 95% 0,75- 2,24). Par ailleurs, notre étude qualitative révèle que les forces du système actuel incluent une bonne qualité des services, mais qu’il existe des faiblesses au niveau de l’accès aux médecins spécialisés, du dépistage systématique et de l’accès aux services à long terme. Nos recommandations incluent le développement d’une approche coordonnée en santé mentale, l’implication automatique d’un gestionnaire de cas et l’amélioration des mécanismes d’accès après le congé.

Made which to measure? Nineteenth century science and sporting bodies

The modification of bodies to enhance performance for competitive sporting purposes originated in the mid eighteenth century. Since then, ‘science’ has informed the discourses of sports training practices, but its influence has changed significantly, now being directive rather than merely being addressed in the ethos of training. Today, sports training practices often are associated with scientific research focussed on understanding the biological processes underpinning physical achievements. However, in the first two centuries of modern sport, science, rather than directing practice, was used as a legitimating, justifying discourse that served to empower training practices.

This paper, an exercise in historical anthropology, replaces conventional ethnographic data with the texts of sports training manuals, sports periodicals and medical journals to examine how these discourses represented the influence of science on the preparation of the body for competition. The focus on the nineteenth century is instructive because, first, physiological models at the century’s start were influenced by Galenic theory, but were underpinned by modern empirical science at its end. Second, from the 1860s, amateurism inspired a major rethinking of training; the ensuing contrast with the preparation of professional athletes illustrates how science was deployed in the making of nineteenth century sporting bodies.

Managing sport in drought-new stakeholders and new governance issues : a case study

Globally, almost every nation is facing some form of water crisis (World Commission on Water 2000). In Australia, the sport and recreation industry is one of the highest consumers of water. Other high water consuming industries (such as agriculture and farming) have been forced to adhere to strict managerial and governance reform due to the water crisis, yet in the sport and recreation industry, such changes are yet to be implemented and fully realised across the sector.

This research examines the impacts of drought and sustainable water management for sport and recreation. Specifically, it provides a case study of sport and recreation provision in a municipality that has already undergone considerable reform due to long-term drought. Sport and recreation use water for purposes such as irrigation of playing fields/pitches, filling swimming pools, stadium amenities and facilities, kitchens, maintenance and cleaning, and clubhouse amenities.

For sports that are heavy users of water for the maintenance of playing fields (such as soccer, Australian Rules football, rugby league, rugby union, grass and clay tennis courts to name a few) the impacts of drought and water restrictions have been severe. Some sports have reported an increase in the risk of injury to participants because of the condition of un-watered playing fields (Sport and Recreation Victoria 2007). Others have been forced to delay or shorten their seasons (Sleeman 2007), or worse still, cancel training and organised competition completely (Connolly and Bell 2007). While the impact of water restrictions has been profound on most sports, there are some sports that are not heavy water users and the impact of drought and water restrictions has been minimal. This problem creates issues and apparent inequities raising the need to further examine water consumption in sport and recreation. The potential outcome that arises is that the future of those sports that cannot conduct their competitions may be disadvantaged, while other sports that do not have such problems may be able to flourish.

Water, and those who control the supply of it, then defines which sports are able to flourish and sustain sport development pathways, compared to those whose survival may be in jeopardy. This research explores the stakeholder management and governance issues that have resulted for sport and recreation in the City of Greater Geelong (CoGG) located in Victoria, Australia--a region in long-term water crisis. The supply of sport and recreation facilities in the CoGG (like most municipalities in Australia) is largely the responsibility of the municipal council. The corporation responsible for the supply of water to the municipality is Barwon Water.

Although other sport and recreation facilities exist in the CoGG, the municipal council of CoGG owns and maintains over 120 sporting ovals (including the stadium used by its professional Australian Football League (AFL) team, the Cats), six swimming pools, and three golf courses. The CoGG host their professional AFL team, a range of local, national and international sport events, and provide a wide range of sport and recreation facilities for the community residents.

Eight interviews were conducted in total. Interviews were conducted with representatives from CoGG municipal council (who are responsible for the delivery of sport and recreation services and facilities in Geelong), and representatives from Barwon Water (who are responsible for the ongoing provision and maintenance of sport and recreation services and facilities) through the provision of water. Results show that the ten highest users of water in the municipality are sport and recreation facilitieswhich between them use almost one-third of the city's total water consumption (City of Greater Geelong 2006).

The municipal council is under considerable pressure to find ways to continue to provide sport and recreation opportunities for community members, as well as professional athletes and teams who use these facilities despite water restrictions. After all, these facilities provide benefit to spectators and participants, as well as businesses that rely on visitors to Geelong for sport and recreation events.

Due to such pressures, from 2007, the CoGG and Barwon Water agreed to provide the sport and recreation sector with water allocations rather than to be denied of all water under the water restriction regimes in place in the municipality. During 2007 summer sport season, this allowed the CoGG to keep 16 of its 120 sporting ovals open for participation through allocating all available water to these fields in order to keep them safe and playable. However, CoGG and Barwon Water were required to devise a rating scale to determine which sports (and sport facilities) were to share the allocated water, and which were not. These decisions also had knock on effects through sports. In order to ensure the safety of the playing surfaces, the CoGG and Barwon Water also restricted use of fields to competition only, therefore sport participants were forced to train on local beaches and other parkland areas-transferring issues of safety and public liability to other locations and facilities in the community. Further, it was reported that scheduling of competition seasons and individual matches; as well as the allocation of "home ground" gate receipts and concessions profits were required to be governed by the CoGG and Barwon Water as the competing sports were unable to agree. Perhaps more importantly, the rating scale developed for water allocation also resulted in some sports being rated as ineligible for water and as a result were unable to stage their entire competitions.

Clearly, the water allocation rating scale, and approach taken in this municipality to the continued delivery of sport and recreation has provided a workable solution. However, this study also signals that new stakeholders have entered the arena for the governance of sport. Governance structures in sport and recreation are being impacted as a result of the water crisis.

Those making decisions about which sport and recreation activities and/or facilities will be assisted with water resources are being made by local councils and water corporations. Sport managers are being required to understand existing areas of knowledge (such as turf management) in different ways, to gain knowledge in new areas (such as sustainable water management), and to lobby new stakeholder groups (such as water corporations) in order to secure their futures. The continued existence of some sports is no longer in the hands of governing bodies, but in the hands of local councils, and water corporations.

Clearly, any of the solutions implemented as discussed above, require multiple stakeholders to interact, and to reach agreement in order to assist in sustainable management of water in sport and recreation. In this sense, the management of water in sport (and all other industries) is more than a rational decision about policy, legislation, restrictions and resource allocations. It is a social and political process requiring scholarly attention for practical solutions.

Body image, drive for muscularity, and social comparisons in men

The results of this thesis indicated that males engage in comparisons when evaluating their bodies and more frequently use similar others, such as friends and the average male for comparison. The results showed that comparisons to males in the media and professional athletes indicated body dissatisfaction and drive for muscularity.The portfolio presents four eating disorder case studies to illustrate how a therapist can use manual-based CBT techniques in a flexible manner and adapt interventions to the individual needs of clients who have motivational issues or present with complex comorbidity, in order to improve treatment outcomes.
