The aims of this study were to analyse perceptions regarding the sporting events held in the Madrid Sports Palace and to analyse whether those perceptions vary by age or gender. One hundred and ninetyfive residents answered the Ntloko and Swart (2008) questionnaire. The dimensions most highly rated were economic benefits (3.9±0.8), the event as a regional showcase (3.6±0.7), and the event as entertainment (3.4±0.6). However, the respondents did not agree with the negative environmental impact (2.0±0.8). Men rated the use of public money (z=2.4; pmenor que.05) and the regional showcase (z=2.0 pmenor que.05) more positively than women. Finally, women rated the increase in prices (z=2.0; pmenor que.05) more highly than men. The age groups differed significantly only regarding the promotion of community pride. Seniors and middle-aged adults rated it more positively than young adults (?2(2)=9.9; pmenor que.01). The fact that in an urban sports facility regular sporting events take place on a regular basis means that there are diverse perceptions, though mainly positive, and those perceptions differ from the perceptions about mega events that take place once in a life time at temporary sports facilities.

Twitter has become a dependable microblogging tool for real time information dissemination and newsworthy events broadcast. Its users sometimes break news on the network faster than traditional newsagents due to their presence at ongoing real life events at most times. Different topic detection methods are currently used to match Twitter posts to real life news of mainstream media. In this paper, we analyse tweets relating to the English FA Cup finals 2012 by applying our novel method named TRCM to extract association rules present in hash tag keywords of tweets in different time-slots. Our system identify evolving hash tag keywords with strong association rules in each time-slot. We then map the identified hash tag keywords to event highlights of the game as reported in the ground truth of the main stream media. The performance effectiveness measure of our experiments show that our method perform well as a Topic Detection and Tracking approach.

Public referenda have gained momentum as a democratic tool to legitimize public mega projects such as hosting the Olympic Games. Interest groups in favour of hosting the Olympics therefore try to influence voters through public campaigns that primarily focus on economic benefits. However, recent studies find no or hardly any economic impact of hosting the Olympics, instead providing evidence for a positive social impact. This raises the question whether citizens consider economic or social factors when deciding on hosting the Olympics. Based on representative survey data from 12 countries, our results suggest that economic factors can influence voting behaviour, although the influence of social factors is stronger.

Este trabalho tem como escopo analisar as influências das normas e das decisões jusdesportivas internacionais no ordenamento jurídico brasileiro. Para isso, alinharam-se as predileções do autor por Esporte, Direito Internacional e Relações Internacionais, assim como por outras ciências, como Geografia. Indubitável a importância do tema para a conjuntura atual, sendo o Brasil sede dos dois principais megaeventos esportivos em 2014 e 2016, a Copa do Mundo Fifa e os Jogos da XXXI Olimpíadas, os Jogos Olímpicos. Essa dissertação foi dividida em quatro capítulos. O primeiro trata da relação entre Esporte, Globalização e Geopolítica, e o segundo capítulo versa sobre o Esporte sob a perspectiva dos Direitos Humanos. Após estudar o Esporte sob a perspectiva do Estado e do Homem, analisam-se as fontes do Direito Desportivo Internacional e o ordenamento jusdesportivo. Os Estados não são os únicos produtores de normas jurídicas. Entidades privadas são capazes de produzir normas, em cooperação ou em conflito com o Estado. Admite-se, portanto, pluralidade de produção normativa. No caso do Direito Desportivo Internacional, optou-se por abordar quatro organizações esportivas internacionais: COI, Wada, Fifa e TAS/CAS, tema do derradeiro capítulo. A influência de seus regulamentos e de seus estatutos se mostrará não apenas nos estatutos e nos regulamentos de suas afiliadas, mas também na legislação nacional. Essas organizações não governamentais de alcance transnacional/internacional têm sua natureza jurídica de acordo com seus estatutos constitutivos. A tentativa de unificação de sistemas jurídicos deve ser abandonada, dando lugar à concepção de harmonização. A dificuldade de harmonização é causada pela pluralidade de Estados e de atores privados que tentam normatizar as relações jurídicas que envolvem o esporte. Desse modo, as influências dessas normas internacionais de caráter privado são marcantes no ordenamento jurídico pátrio. Analisa-se como ocorrem essas influências e de que forma cada produtor de norma jurídica poderia atuar para que prevaleça a cooperação entre eles no âmbito jusdesportivo.

Demonstrating socially responsible behaviour has become increasingly important for corporations. Using the Psychological Continuum Model (PCM) as its theoretical framework, this paper examines the meditational role of corporate social responsibility (CSR) on the relationship between sport participation motivation, event attachment and purchase intent of a sport event’s sponsors’ products. A questionnaire was distributed to a sample of sport event participants (N=689) to measure sport participation motivation (recreation and charity), attachment to the event, CSR, and purchase intent of sponsors’ products. Results reveal that CSR fully mediates the link between purchase intent and sport participation motivation and partially mediates the influence of attachment on purchase intent. The authors propose that corporations strategically align with sport events in which participants are attached to allow for CSR and the meaning elicited by the event to work jointly.

Muscle physiologists often describe fatigue simply as a decline of muscle force and infer this causes an athlete to slow down. In contrast, exercise scientists describe fatigue during sport competition more holistically as an exercise-induced impairment of performance. The aim of this review is to reconcile the different views by evaluating the many performance symptoms/measures and mechanisms of fatigue. We describe how fatigue is assessed with muscle, exercise or competition performance measures. Muscle performance (single muscle test measures) declines due to peripheral fatigue (reduced muscle cell force) and/or central fatigue (reduced motor drive from the CNS). Peak muscle force seldom falls by >30% during sport but is often exacerbated during electrical stimulation and laboratory exercise tasks. Exercise performance (whole-body exercise test measures) reveals impaired physical/technical abilities and subjective fatigue sensations. Exercise intensity is initially sustained by recruitment of new motor units and help from synergistic muscles before it declines. Technique/motor skill execution deviates as exercise proceeds to maintain outcomes before they deteriorate, e.g. reduced accuracy or velocity. The sensation of fatigue incorporates an elevated rating of perceived exertion (RPE) during submaximal tasks, due to a combination of peripheral and higher CNS inputs. Competition performance (sport symptoms) is affected more by decision-making and psychological aspects, since there are opponents and a greater importance on the result. Laboratory based decision making is generally faster or unimpaired. Motivation, self-efficacy and anxiety can change during exercise to modify RPE and, hence, alter physical performance. Symptoms of fatigue during racing, team-game or racquet sports are largely anecdotal, but sometimes assessed with time-motion analysis. Fatigue during brief all-out racing is described biomechanically as a decline of peak velocity, along with altered kinematic components. Longer sport events involve pacing strategies, central and peripheral fatigue contributions and elevated RPE. During match play, the work rate can decline late in a match (or tournament) and/or transiently after intense exercise bursts. Repeated sprint ability, agility and leg strength become slightly impaired. Technique outcomes, such as velocity and accuracy for throwing, passing, hitting and kicking, can deteriorate. Physical and subjective changes are both less severe in real rather than simulated sport activities. Little objective evidence exists to support exercise-induced mental lapses during sport. A model depicting mind-body interactions during sport competition shows that the RPE centre-motor cortex-working muscle sequence drives overall performance levels and, hence, fatigue symptoms. The sporting outputs from this sequence can be modulated by interactions with muscle afferent and circulatory feedback, psychological and decision-making inputs. Importantly, compensatory processes exist at many levels to protect against performance decrements. Small changes of putative fatigue factors can also be protective. We show that individual fatigue factors including diminished carbohydrate availability, elevated serotonin, hypoxia, acidosis, hyperkalaemia, hyperthermia, dehydration and reactive oxygen species, each contribute to several fatigue symptoms. Thus, multiple symptoms of fatigue can occur simultaneously and the underlying mechanisms overlap and interact. Based on this understanding, we reinforce the proposal that fatigue is best described globally as an exercise-induced decline of performance as this is inclusive of all viewpoints.

O objetivo do estudo foi compreender quais as estratégias de preparação de voluntários para a atuação em megaeventos esportivos no Brasil. A pesquisa foi de natureza qualitativa e de cunho exploratório, tendo como técnica para a coleta de dados a entrevista com roteiro de perguntas semiestruturado e o caderno de campo. A entrevista foi realizada com o responsável pelo programa de treinamento dos voluntários do V Jogos Mundiais Militares (2011) sobre a organização realizada. A análise do conteúdo (BARDIN, 2011) foi utilizada para análise das experiências relatadas de acordo com 3 categorias: perfil do voluntariado esportivo e do líder de voluntários; dificuldades em se trabalhar, compreender e valorizar o voluntariado no esporte e modelo de treinamento e de gestão do programa de voluntários esportivos. Os resultados desta pesquisa contribuíram para a literatura nesta temática, bem como ponto de partida para o design e coleta de dados de pesquisas sobre voluntários para os próximos megaeventos esportivos que serão sediados no Brasil, Copa do Mundo de 2014 e Jogos Olímpicos de 2016.

O presente documento apresenta sucintamente os conceitos e definições das geotecnologias, com ênfase em duas ferramentas tecnológicas de suporte a utilização desta metodologia: o geoprocessamento e o sistema de informação geográfica (SIG). A proposta metodológica da utilização da geotecnologias teve como objetivo a observação dos fenômenos dos megaeventos esportivos, que serão sediados na cidade do Rio de Janeiro, a Copa do Mundo de Futebol 2014 e os Jogos Olímpicos e Paralímpicos de 2016, bem como atender as exigências de conclusão da tese de doutorado. Para tal, foram realizados dois artigos que observaram o fenômeno megaeventos esportivos no espaço geográfico da cidade do Rio de Janeiro. O primeiro verificou as mudanças urbanas com as características socioeconômicas ocorridas nas proximidades do parque olímpico, a partir de uma visão temporal da década de 2000. O segundo artigo observou o espaço geográfico da cidade junto aos sítios olímpicos e as mudanças climáticas que vêm ocorrendo nesses locais, através da observação da evolução da temperatura de superfície com a construção de mapas termais, e de dados meteorológicos.

This study examined the operational planning, implementation and execution issues of major sport events, as well as the mitigation and management strategies used to address these issues, with the aim of determining best practices in sport event operational planning. The three Research Questions were: 1) What can previous major sport events provide to guide the operational management of future events? 2) What are the operational issues that arise in the planning and execution of a major sport event, how are they mitigated and what are the strategies used to deal with these issues? 3) What are the best practices for sport event operational planning and how can these practices aid future events? Data collection involved a modified Delphi technique that consisted of one round of in-depth interviews followed by two rounds of questionnaires. Both data collection and analysis were guided by an adaptation of the work of Parent, Rouillard & Leopkey (2011) with a focus on previously established issue and strategy categories. The results provided a list of Top 26 Prominent Issues and Top 17 Prominent Strategies with additional issue-strategy links that can be used to aid event managers producing future major sport events. The following issue categories emerged as having had the highest impact on previous major sport events that participants had managed: timing, funding and knowledge management. In addition, participants used strategies from the following categories most frequently: other, formalized agreements and communication.
