The research is characterized as descriptive exploratory, having 30 rowers of the male sex with age between 15 and 28 years old as participants. The data was collected using the Board of balance, developed by Soares (2004), constituted of a convex inferior surface, which possess 5 concentric rings divided and isolated in 8 parts, arranged in a total diameter of 76 mm (± 0,01). The analysis of the data was preceded starting from Shapiro-Wilk's Normality test, followed by the Wilcoxon and Kruskal-Wallis tests. Through the results it was noticed that the visual information influenced in the maintenance of the balance when the rowers were with two feet in contact with the soil. It was verified a heterogeneity in the characteristics of the log balance for each group related to the visual information, when the rowers were with the support of the dominant foot in contact with the soil. When the rowers were with the support of the foot non dominant in contact with the soil, with and without visual information, the results showed that there was probably compensation among the sensorial systems and that the visual information seemed to influence in the maintenance of the equilibrium. The results indicated that with the support of the two feet in contact with the soil with visual information there are differences in the oscillations among the rowers' groups, and among the rowers' groups just Team and PreTeam didn't show difference in the performance. When was analyzed the support of the two feet and of the dominant foot in contact with the soil with visual information, it was observed that just in the group of the rowers' Team didn't happen significant differences in the acting of the task, however it wasn't noticed differences in the acting of the tasks when the support of the foot in the soil was made with the dominant and with the no dominant foot. The results regarding the characteristics of the balance of rowers' log, in the seated position, with different supports of the feet in contact with the soil, without visual information, showed that there weren't significant differences among the acting of the equilibrium of the rowers' log, in the three different supports of the feet. It is conclude that this study brought subsidies to affirm the hypothesis that the log balance in the seated position is directly related to the concepts of the control of the balance in the stand position, being able to this way come to contribute for the subject that involve the development, the performance of the human balance, as well as for the aspects of the rowers' technical training, being necessary a continuity in the investigations, for to have others information that will make possible a better understanding regarding the trunk balance, in the seated position for different populations. / O objetivo deste estudo foi avaliar as características do equilíbrio de tronco de remadores, na posição sentada. A pesquisa é caracterizada como descritivo exploratória, tendo 30 remadores do sexo masculino com idade entre 15 e 28 anos como participantes. Os dados foram coletados usando uma prancha de equilíbrio, desenvolvida por Soares (2004), constituída de uma superfície inferior convexa, que possui 5 anéis concêntricos divididos e isolados em 8 partes, dispostos num diâmetro total de 76 mm (± 0,01). A análise dos dados procedeu-se a partir do teste de Normalidade Shapiro-Wilk, seguido dos testes Wilcoxon e Kruskal-Wallis. Através dos resultados percebeu-se que a informação visual influenciou na manutenção do equilíbrio quando os remadores estavam com os dois pés em contato com o solo. Verificou-se uma heterogeneidade nas características do equilíbrio de tronco para cada grupo relacionado à informação visual, quando os remadores estavam com o apoio do pé dominante em contato com o solo. Quando os remadores estavam com o apoio do pé não dominante em contato com o solo, com e sem informação visual, os resultados mostraram que provavelmente houve uma compensação entre os sistemas sensoriais e que a informação visual pareceu influenciar na manutenção do equilíbrio. Os resultados indicaram que com o apoio dos dois pés em contato com o solo, com informação visual, há diferenças nas oscilações dentro dos grupos de remadores, e entre os grupos de remadores apenas Equipe e Pré ¿ Equipe não mostraram diferença no desempenho. Quando se analisou o apoio dos dois pés e do pé dominante em contato com o solo com informação visual, observou que apenas no grupo de remadores da Equipe não ocorreram diferenças significativas no desempenho da tarefa, porém não se notou diferenças no desempenho das tarefas quando o apoio do pé no solo era feito com o dominante e com o não dominante. Os resultados referentes às características do equilíbrio de tronco de remadores, na posição sentada, com diferentes apoios dos pés em contato com o solo, sem informação visual, mostraram que não houve diferenças significativas entre o desempenho do equilíbrio de tronco dos remadores, nos três diferentes apoios dos pés. Conclui-se que este estudo trouxe subsídios para afirmar a hipótese de que o equilíbrio de tronco na posição sentada está diretamente relacionada aos conceitos do controle do equilíbrio na posição em pé, podendo deste modo vir a contribuir para as questões que envolvem o desenvolvimento, o desempenho do equilíbrio humano, bem como para os aspectos do treinamento técnico dos remadores, sendo necessária uma continuidade nas investigações, para ter outras informações que possibilitarão um melhor entendimento a respeito do equilíbrio de tronco, na posição sentada para diferentes populações.

A desordem temporomadibular em atletas da modalidade do remo é uma temática ainda pouco abordada na literatura, muito embora se tenha conhecimento que a biomecânica do gesto esportivo possa provocar dores lombares, fratura de costela devido ao estresse, além de dores cervicais provenientes do desprendimento de força, para atingir grande velocidade e manutendo o equilíbrio por um longo tempo. O presente estudo tem como objetivo analisar, por meio da baropodometria dinâmica, a ação da placa oclusal estabilizadora associada ao exercício terapêutico de movimento mandibular em atletas remadores diagnosticados como portadores de desordem temporomandibular (DTM). Estudos prévios demonstram que um dispositivo intraoclusal (placa oclusal estabilizadora) tem ação significante sobre o sistema de manutenção do equilíbrio corporal na postura estática. Trinta indivíduos remadores apresentaram-se como voluntários com queixa de dor, sendo 10 deles (40% homens e 60% mulheres), com idade entre 24 e 35 anos foram diagnosticados com DTM por meio do preenchimento do questionário RDC/TMD e de exame clínico. O presente estudo piloto foi caracterizado por ser um ensaio clínico, randomizado, controlado, prospectivo e de intervenção. Imediatamente após aplicação do questionário e do exame clínico, todos os indivíduos realizaram testes de baropodometria estática e dinâmica. Após esta etapa, realizou-se a randomização dos grupos por meio de software online gratuito (www.random.org) que determinou os integrantes do grupo controle, denomindado de Grupo Exercício (GE) e grupo teste denominado de Grupo Placa (GP). Ambos os grupos receberam orientação para a realização do exercício terapeutico de movimento mandibular. Definidos os integrantes do GP, foram realizados agendamento para a realização da etapa de confecção da placa oclusal. Os grupos foram monitorados por 12 semanas e após este período foram reavaliados segundo os mesmos parâmetros da etapa inicial. A análise estatísitca foi realizada utilizando o modelo ANOVA (normalidade e homoscedasticiodade),teste T-Student e teste não paramétrico de Wilcoxon. Os resultados apresentaram significância estatística na redução da dor e aumento da amplitude articular da articulação temporomandibular (ATM) no GP (p<0,05). Não foi observada significância estatísitica na análise da pressão plantar dinâmica, justificado pelo fato da insuficiência do número de invidíduos da amostra. Concluiu-se que o uso da placa oclusal foi eficaz no tratamento da DTM pela redução do quadro doloroso, entretanto, uma amostragem maior se faz necessária pra a verificação da integração entre sistema estomatognático e postural na dinâmica da marcha. / Temporomadibular joint disorder (TMJD) in rower athletes has still few studies over this theme, where the biomechanics of athletic gesture points can produce low back pain, rib stress fractures and cervical pain as resulting from power requirement to obtain high speed and body balance for repeatedly long period exercises. The aim of this study was to analyze through dynamic plantar pressure the effects of occlusal splint and therapeutic exercise of mandibular movement in rowers diagnosed as suffering from TMJD. Previous studies have shown that the occlusal splint has significant action to keep the system of body balance in standing position. 30 rower athletes came as volunteers with pain symptoms, and 10 individuals, 40% men ande 60% women, aged between 24 and 35 years, were diagnosed with TMJD through completion of the RDC/TMD questionnaire and clinical examination. The research was performed by a randomized controlled prospective clinical study besides intervention. Immediately after the questionnaire application and clinical examination, all individuals performed tests of static and dynamic baropodometry. After this procedure, the groups were randomized by using a free online software (www.random.org) which determined the members of control group, named Exercise Group (EG) and test group called Oclusal Splint Group (OSG). Both groups received guidance for performing only therapeutic exercise of mandibular movement. The OSG were scheduled for the completion of preparation stage for occlusal splint. All groups were monitored for 12 weeks and after this period were evaluated according to the same parameters of the initial step. Statistic analysis was performed by using ANOVA model (normal and homoscedasticity), t-Student test and Wilcoxon nonparametric test. The results showed statistical significance to pain relief and increase of amplitude range of jaw joint in OSG (p < 0.05). No statistical significance was observed in the analysis of dynamic plantar pressure, justified by insufficient statistic population. In conclusion the use of occlusal splint was effective in the treatment of TMJD to pain relief, however, a larger sampling is necessary to verify the integration among stomatognatic system, posture and and gait dynamics analyzes.

The purpose of this present study was to assess the feasibility and determine the potential short-term efficacy of implementing a specific 9-week “Yoga for Rowers” (ROWGA) program on male varsity rowers during a competitive training season. Sixteen competitive male varsity rowers (20.6 ± 2.1 years) were recruited to participate, using a single group, pre-test-post-test, quasi-experimental research design. All participants performed two 60 min ROWGA sessions per week for 9 weeks during their fall competitive season. The primary objectives were to test the efficacy of a ROWGA program in a real-world context by evaluating: 1) the feasibility of implementing the program during the training and competitive season as measured by program adherence; 2) its potential effect on strength by evaluating hip muscle strength acting in the sagittal, frontal, and transverse planes as well as on hip muscle strength ratios between the agonist versus antagonist muscle groups; and 3) its potential effect on hip flexion range of motion (ROM). Two pre-test baseline measurements were performed on all participants over 1- week prior to initiating the ROWGA sessions while a single post-test was conducted following the ROWGA intervention. Intraclass correlation coefficients for ROM and strength were used to determine reliability of measurements by taking the two pre-intervention test scores. Outcome measures included hip flexion range of motion, peak isometric hip muscle forces normalized to body weight, including hip flexors, extensors, abductors, adductors, both internal and external rotators as well as peak isometric agonist-antagonist hip muscle strength ratios. Pre and post peak isometric hip strength measurements were calculated for agonist-antagonist muscle groups within each plane by dividing flexors by extensors, adductors by abductors, and internal by external rotators. Feasibility of the ROWGA program was determined from program attendance and adherence rates. The adherence rate was considered high with 89% attending all sessions, after adjusting for compulsory competitions. Significant improvements in peak isometric strength were demonstrated for hip flexors, extensors, abductors, and adductors, and external rotators, while a significant reduction for hip flexion ROM was observed. No significant changes in isometric hip muscle strength agonist-antagonist ratios were demonstrated. The results from this research support the feasibility of the ROWGA program in terms of rower’s acceptance, adherence, and the ability to accommodate the time requirements within their schedule as well as potential strength benefits gained. This research could help provide a platform for future large-scale research related to injury prevention in rowing. / Graduate / 2021-04-06

Title: Kinesiological analysis of the rowing stroke on a single scull and on a rowing ergometer Concept 2 comparison Purposes: The purpose of the present study was to determine a specific structure in timing of selected muscles during two movement patterns - rowing on a single scull and rowing on an ergometer Concept 2. Methods: By surface electromyography we recorded muscular activity, synergies and involvement throughout mean cycle of the rowing stroke. Results: The mutual correlations of mean EMG curves of all measured muscles showed, that there were not found any differences in inter-locomotive synchronization of selected muscles. Established values of correlation (r) showed higher level of dynamic balance (performance similarity between both measured activities. Determination of the muscular activity timing considering onsets and cessations, was in the percentual results explication of the movement cycle inter-locomotive different. Conclusion: Results showed a great similarity in synergies organizing the muscular coordination in between both measured physical activities. But timing of the movement was different in the moments of muscular activity onsets during rowing and during ergometer rowing. This may be attributed to the specificity of on-water locomotion.

In early 2020, many businesses (including gyms) were instructed to shut down for an unspecified period of time as a response to the SARS-CoV-2 virus (Casagrande et al., 2020, p.1; Erskine, M., 2020, para.1; O’Brien, 2020, Gyms and Health Centers section, para.1-16). As a result, many people experienced a change in how much they exercised and the quality and quantity of their sleep (Antunes et al., 2020, pp.3,5; Bigalke et al., 2020, p.7; Cellini et al., 2021, pp.113- 115, 117; Constandt et al., 2020, p.4; Pérez-Carbonell et al., 2020, pp.164, 166; Puccinelli et al., 2021, p.6). There was also an increase in the levels of negative mental states, such as anxiety and depression in various populations (Daly et al., 2020, pp.2-5). This study primarily explored changes in exercise and sleep (quality and quantity) as a result of the pandemic in a highly athletic adult population of rowers and triathletes. The data collected from the study also touched upon the changes in the mental states of the participants. A survey was sent across Canada to rowing and triathlon clubs from SurveyMonkey that had both qualitative and quantitative questions to examine these areas of contention. A majority of participants indicated that their sleep quality had worsened as a result the COVID-19 pandemic. However, there wasn’t enough evidence to indicate that the pandemic affected the length of their sleep. The athletic performance of the athletes, as measured by self-report, decreased during the pandemic in an overwhelming number of participants. Finally, although there were many indications of worsened mental health states (such as reports of increased anxiety), there wasn’t a validated questionnaire used to measure changes in mental health concerns in the population related to the COVID-19 pandemic. Some mental health concerns that were shared by the participants indicated other causes than only the pandemic. Future research should include more objective measures of sleep duration and anxiety and depression scores to better clarify those hypotheses. / Graduate

In Marked Men: Sport and Masculinity in Victorian Popular Culture, 1866-1904 I examine the representation of the figure of the Victorian sportsman in different areas of nineteenth-century popular culture – newspapers, spectacular melodrama, and series detective fiction – and how these depictions register diverse incarnations of this figure, demonstrating a discomfort with, and anxiety about, the way in which the sporting experience after the Industrial Revolution influenced gender ideology, specifically that related to ideas of manliness. Far from simply celebrating the modern experience of sport as one that works to produce manly men, coverage in the Victorian press of sporting events such as the 1869 Oxford-Cambridge Boat Race, spectacular melodramas by Dion Boucicault, and series detective fiction by Arthur Conan Doyle and Arthur Morrison, all recognize that the relationship between men and modern sport is a complex, if fraught one; it produces men who are “marked” in a variety of ways by their sporting experience. This recognition is at the heart of our own understandings of this relationship in the twenty-first century. / Thesis (Ph.D, English) -- Queen's University, 2012-08-01 15:16:09.384
