Orientador: Orival Andries Júnior / Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Educação Física / Made available in DSpace on 2018-08-22T22:03:57Z (GMT). No. of bitstreams: 1 Lima_CarolinaMartins_M.pdf: 1429127 bytes, checksum: 645e26f53455ecb88a9e0f3771a1876b (MD5) Previous issue date: 2013 / Resumo: A Hipermobilidade Articular Generalizada é uma disfunção que dá ao indivíduo capacidade de realizar movimentos articulares exagerados, e na natação é necessário grande amplitude para uma performance eficiente. Sendo assim, o estudo teve como objetivo, verificar a influência da hipermobilidade articular, na performance e no índice de lesões de atletas voluntários na natação. Para isso, foram avaliados 20 atletas do estado de São Paulo, de ambos os sexos, de 15 a 20 anos de idade, e separados em três grupos, atletas com HAG (grupo 1), atletas sem HAG (grupo 2) e todos os atletas (grupo 3). Os dados foram obtidos através dos critérios de Carter e Wilkinson, parcialmente modificados por Beighton e Horan para diagnosticar HAG e flexiteste nas articulações de ombro e tornozelo para complementar o estudo. O Inquérito de Morbidade Referida adaptado foi utilizado para análise da incidência de lesão. Ainda, realizou-se filmagem em campo aberto de um estimulo máximo de 50 metros no nado crawl para avaliação da performance, sendo analisados tempo e frequência de braçadas. Observou-se que os atletas que apresentaram HAG consequentemente tiveram maior flexíndice. Quando analisado o desempenho, o grupo 1 apresentou menor frequência de braçadas, maior comprimento de braçadas e maior velocidade. Além do que, o tempo para execução do nado foi menor para o grupo 1, corroborando a hipótese de a HAG melhorar a performance do atleta de natação, apesar de não apresentar significância estatística. Com relação à incidência de lesão, o grupo 1 apresentou maior incidência de lesões osteoarticulares, percebidas no treino aquático, e principalmente no joelho, ombro e tornozelo, e o grupo 2 apresentou menor incidência de lesão, acometendo mais lesões do tipo musculares, percebidas na musculação e principalmente no ombro. Sendo assim, pôde-se concluir que os atletas com HAG apresentaram maior incidência de lesão e melhor performance que os atletas de natação sem HAG / Abstract: The Generalized Joint Hypermobility (GJH) is a disorder which gives the individual the ability to perform joint exacerbated movements, and the swimming uses movements of large amplitude for efficient performance. Thus, the study aims to verify the influence of GJH in the occurrence of injuries and overall performance of swimmers volunteers, since little has been reported on the influence of hypermobility and swimming. To do so, we evaluated 20 athletes in the state of São Paulo,, of both sexes, 15-20 years, and separated into three groups, athletes with GJH (group 1), GJH athletes without (group 2) and all athletes (group 3). The data has been obtained using the criteria of Carter and Wilkinson, partially modified by Beighton and Horan to diagnose and GJH flexitest in joints of shoulder and ankle. The Morbidity Survey adapted was used for analysis of injury incidence. More filming in the open for a stimulus of 50 meters freestyle at full speed for performance analysis, and analysis time and stroke rate. It has been observed that the incidence of GJH is provided above and Flexindex increases when there are GJH. When analyzing the performance, it was noted that the stroke rate, stroke length and speed were higher in the group 1. In addition to the time for running the swimming was lower for the group 1, corroborating the hypothesis that the GJH improve athletic performance swimming, despite not being statistically significant. Regarding the incidence of injury, the group 1 showed more osteoarticular lesions, seen in the water training, and especially in the knee, shoulder and ankle, and the group 2 showed a lower incidence of injury, most common injuries like muscle, and mainly perceived in bodybuilding and particularly the shoulder. To sum up, it is possible to conclude that athletes with GJH have had a higher incidence of injury and better performance than the swimmers without GJH / Mestrado / Biodinamica do Movimento e Esporte / Mestre em Educação Física

Sendo, o Balanço Hídrico um componente importante nos estudos aplicados na gestão de bacias hidrográficas. Entretanto, um problema encontrado no cálculo deste balanço é a estimativa da evapotranspiração de referência (ETo), um dos mais importantes componentes do balanço hídrico e, ao mesmo tempo, uma das variáveis mais complexas de quantificar. Isto se deve, dentre outros fatores, ao fato das medições serem escassas e dispendiosas. Este trabalho busca estimar a evapotranspiração diária na microbacia hidrográfica do riacho Gameleira, inserida na sub-bacia do rio Tapacurá, localizada na parte Nordeste da Mesoregião Geográfica do Agreste do Estado de Pernambuco. Os dados utilizados na pesquisa são da estação climatológica localizada na Escola Agrotécnica Federal de Vitória de Santo Antão – PE. O período escolhido para simulação foi de 2004 a 2008. Para preencher as falhas existentes na série foram utilizados dados da estação do Laboratório de Meteorologia de Pernambuco (LAMEPE) de Recife, validados por análises estatísticas. E para o cálculo da ETo aplicou-se o modelo SWIM com o método de Penman-Monteith (FAO56), da Food and Agriculture Organization – FAO, e o método modificado de Turc-Ivanov. Como resultados da pesquisa tem-se a calibração do modelo SWIM para estimar a ETo, destacando-se o bom desempenho do método modificado de Turc-Ivanov comparado com o método recomendado pela FAO. Ao final, foi possível estimar a ETo por um método, que requer apenas as seguintes variáveis climatológicas: radiação solar e temperatura do ar. Indicando que métodos mais simples podem apresentar bons resultados na estimativa da Eto, e assim, auxiliar na gestão de bacias hidrográficas.

All kids out of the pool!: brand identity, television animations, and adult audience of Cartoon Network's Adult Swim

Lee, Hye Jin 01 May 2013 (has links)
This dissertation examines Adult Swim, Cartoon Network's late-night programming block, which has developed into one of the most popular entertainment brands for adults. Expressing and shaping adult sensibilities of the time Adult Swim has been able to become the most popular cable network for (male) adults 18 to 34 years old. Launched in 2001, Adult Swim emerged at a moment in the U.S. when technological developments were changing the television landscape and the meaning of adulthood was fervently being discussed in the media as assumptions and realities of adult life continued to be in conflict. The goal of this dissertation is to understand the contemporary society and media culture as well as the defining characteristics and tensions of contemporary adulthood, adult taste, and adult culture by investigating Adult Swim's rise to a popular entertainment brand among young adults. Through a contextualized critical analysis of selected Adult Swim television texts, representation of Adult Swim in the mainstream press, and Adult Swim fans' online discussions in Adult Swim's official message boards this dissertation interrogates what branding/programming strategies it uses to appeal to its "adult" viewers, how it constructs and understands its "adult" viewers, and how it establishes its brand identity. With its low-budget, Do-It-Yourself (DIY) style of cartoon and live comedy series that are full of ironic, pop culture references and absurd, surreal humor, Adult Swim has established a unique sensibility that resonates with many young adults and built itself as a "different" and "creative" network brand. However, this dissertation demonstrates that Adult Swim's "unconventional," "edgy" brand identity relies on its male-centric programming strategies that either render women invisible or make use of blatantly sexist jokes for its "adult" appeal. In addition, this dissertation explains that despite featuring many queer characters Adult Swim appropriates queer identity and politics to advance itself as a "subversive," "non-mainstream" and "different" network (a brand identity that greatly appeals to young adults) rather than to subvert heteronormativity and promote LGBT rights. Furthermore, this dissertation interrogates how Adult Swim uses interactive media to invite its viewers to participate in shaping and maintaining its brand identity as a network that "listens to" its viewers and to form sensibility and feelings of conand to construct o form an affective relationship with the Adult Swim brand and to establish itself as a brand that "listens to" and understands the sensibility, affect, and feelings of contemporary young adults who comprise the Adult Swim audience.

Upper body strength and endurance and its relationship with freestyle swim performance in elite swimmers

Storck, Natalie January 2017 (has links)
Background: Strength is considered an important part in swimming and is usually included in training programs for swimmers. However, studies assessing the relationship between muscle strength, muscle endurance and swim performance are not many and have showed different results. Aim: The aim of this study was to assess the correlation between bench press, pull-up and 400 meter freestyle swim performance in elite swimmers. Method: The subjects (n=15, age 16-20) performed a one repetition maximum (1RM) bench press test to measure maximal muscle strength and to measure muscle endurance the subjects performed as many pull-up repetitions as possible during 30 seconds. A velocity four (V4) speed test was performed to assess swim performance by measuring time over covered distance and blood lactate levels. Results: The results of this study showed a moderate correlation (r=-0.54) between one repetition maximum in bench press and 400 meter freestyle swim performance. It showed a strong correlation (r=-0.63) between number of pull-ups repetitions during 30 seconds and 400 meter freestyle swim performance. Conclusion: These results suggest that upper body strength contributes to swim performance over 400 meter. The stronger correlation between pull-ups and swimming may indicate that muscle endurance of m. latissimus dorsi and the back muscles may be important to incorporate in a training program since it has shown to have a strong correlation with swim performance at 400 meters. / Bakgrund: Styrka anses vara en viktig del i simning och är ofta inkluderat i träningsprogram för simmare. Dock har endast ett mindre antal studier undersökt relationen mellan muskelstyrka, muskel uthållighet och simprestation och de som har gjort det visar olika resultat. Syfte: Syftet med denna studie var att utvärdera korrelationen mellan bänkpress, pull-ups och 400m simprestation hos elitsimmare. Metod: Deltagarna (n=15, ålder 16-20) utförde ett en repetition maximum (1RM) i bänkpress för att mäta maximal muskel styrka och för att mäta muskeluthållighet utförde deltagarna så många pull-ups repetitioner som möjligt under 30 sekunder. Ett velocity four (V4) hastighets test utfördes för att utvärdera simprestation genom att mäta tid över simmad distans och blod laktat värden. Resultat: Resultatet i denna studie visade på en moderat korrelation (r=-0,54) mellan en repetition maximum i bänkpress och 400 meter fristil simprestation. Den visade på en stark korrelation (r=-0,63) mellan antalet pull-ups repetitioner under 30 sekunder och 400 meter fristil simprestation. Konklusion: Dessa resultat tyder på att överkroppsstyrka bidrar till simprestation över 400 meter. Den starkare korrelationen mellan pull-ups och simning kan indikera att muskeluthållighet hos m. latisimus dorsi och ryggmusklerna kan vara viktigt att lägga in i ett träningsprogram då det visat på en stark korrelation till simprestation på distansen 400 meter.

Resisted Sprint Training in Swimming : A Quasi-Experimental Study on Swedish National Level Swimmers

Lutula, Antonio January 2019 (has links)
Aim The aim of this study was to ascertain the effect of resisted sprint training in swimming on maximal swimming velocity and performance characteristics. The aim was also to examine how maximal swimming velocity is related to maximal swim power and maximal dry-land power. Method Eighteen competitive national level swimmers (9 male and 9 female; age: 18.3 ± 2.3 years, body mass: 72 ± 8.3 kg, height: 177.2 ± 4.6 cm, mean ± SD) were recruited to this study. Subjects were assigned to either resisted sprint training (RST) or unresisted sprint training (UST). Sprint training was performed two times per week during 6 weeks as 8x15m with a 2min send-off interval. RST performed sprint training using individualized load corresponding 10% of maximum drag load (L10), UST performed sprint training with no added resistance. A test-battery including dry-land strength assessment; maximal strength (MxS) and explosive strength (ExS), a timed 25m front-crawl swim and in-water force-velocity profiling was performed prior and following the training intervention. Maximal swim power (Pmax), maximum drag load (F0), theoretical maximum velocity (v0) and slope of force-velocity curve (SFv) was computed though force-velocity profiling. Results No significant within group differences occurred in neither RST nor UST following the 6-week intervention period in: swimming velocity, MxS, ExS, Pmax, F0, v0, and SFv. Strong correlations were found between swimming velocity and MxS (r = 0.75), ExS (r =0.82) and Pmax (r = 0.92). Conclusion Resisted sprint training in swimming using L10 did in the present study not elicit any improvements in maximal swimming velocity or examined performance characteristics. Resisted sprint training does not appear to be a superior method of improving swimming performance compared to unresisted sprint training. MxS, ExS and Pmax can be used as robust predictors of swim performance, however only Pmax was found to be casually related to swimming velocity.

Komparativ analys av HTTP och AMQP i System Wide Information Management / Comparative analysis of HTTP and AMQP in System Wide Information Management

Håkansson, Anna January 2024 (has links)
Med en ökande tillväxt inom flygtrafikbranschen behöver de bakomliggande flygtrafikledningssystemen uppgraderas för att möta den växande komplexiteten i syfte att säkerställa en ordnad flygtrafik. Här anses det arkitekturella konceptet System Wide Information Management (SWIM) för distribuerade flygledningssystem vara lösningen för att bygga system som är lättare att underhålla och enklare kan kan samverka med varandra. År 2021 fastslog Europeiska unionen att samtliga operativa intressenter inom det aeronautiska informationsutbytet i EU skall tillhandahålla och kunna konsumera SWIM-tjänster och erbjöd då en uppsättning tjänstegränssnittsbindningar för intressenter att hävda foglighet med för att efterfölja de nya regleringarna. Bland dessa finner vi AMQP Messaging och WS Light som utiliserar AMQP respektive HTTP som meddelandeprotokoll. Tidigare forskning har visat att AMQP presterar bättre än HTTP inom de flesta områden, men denna studie undersöker om någon av de två lämpar sig bättre som meddelandeprotokoll för en europabaserad SWIM-implementation genom att analysera resultatet i en SWIM-kontext. Med hjälp av en komparativ analys och kvantitativ dataanalys jämförs de två meddelandeprotokollen i denna studie för att identifiera liknande och åtskiljande karaktärsdrag samt för att svara på om någon av de två lämpar sig bättre för ändamålet. De punkter protokollen jämförs på är struktur, overhead och effektivitet, interoperabilitet och kompabilitet, tillförlitlighet och feltolerans samt förekomster i Eurocontrols SWIM Registry. Studiens resultat visar att AMQP är den lämpligaste kandidaten av de två sett till implementationstrender och prestanda, men att det är bör göras en avvägning innan en intressent väljer vilket gränssnitt denne skall implementera. / With an increasing growth within the aviation industry, the underlying air traffic control systems needs to be upgraded to meet the growing complexity for ensuring an organized air traffic. This is where the architectural concept System Wide Information Management (SWIM) for distributed air traffic control systems is believed to be the solution for building systems that are easier to maintain and can cooperate with ease. In the year 2021, the European Union decided that all operative stakeholders within the aeronautical information exchange in EU shall provide and be able to consume SWIM services, and provided a set of service interface bindings for stakeholders to claim conformance to in order to follow the new regulations. Among these we find AMQP Messaging and WS Light that utilizes AMQP and HTTP, respectively, as messaging protocols. Previous research has shown that AMQP performs better than HTTP in most areas, but this study analyses the result in a SWIM context to see if any of the two is a more suitable messaging protocol in a Europe based SWIM implementation. Through a comparative analysis and a quantitative data analysis the two messaging protocols are compared in this study to identify similar and distinctive characteristics to answer whether one of the two is a better candidate for the purpose. The protocols are compared on their structure, overhead and efficiency, interoperability and fault tolerance, and their occurances in Eurocontrol's SWIM Registry. The result of the study shows that AMQP is the more suitable candidate of the two, in regards to trends in current implementations as well as performance metrics, but a stakeholder should make a trade-off before choosing what service interface binding to implement.

彩色游泳影片中之泳姿分類

劉明哲, Liu, Ming-Je Unknown Date (has links)
本論文的主要目的是建立一套泳姿自動分類系統,利用電腦視覺中影像處理技術,輔以資料分析技術,即時且自動的分析在一段從岸邊水上拍攝,包含單一泳者向著鏡頭方向游泳的彩色影片中,泳者所進行的姿勢。首先我們利用膚色模型分離出影像中屬於游泳者手臂的區域。接下來,我們分析這些區域的特徵,例如長寬比以及斜率、面積等。最後,基於連續影像中每個單一畫面的手臂區域特徵,利用一個評分系統來判斷該泳者目前所進行的是哪一種游泳姿勢,分為蝶式、仰式、蛙式、自由式等四種泳姿。在實驗結果中,我們所提出的方法對於從http://swim.ee網站上下載的50段影片中,四種泳姿的分類達到了百分之百的正確性。 / In this thesis, we present a robust method to classify swimming styles from live color video sequences based on the features extracted from the upper-body of the swimmer. In our approach, potential body parts are first extracted using a simple skin color model. Next, the dominant components in the segmented regions are selected according to quantitative measures such as the aspect ratio and the area. Regression analysis is then performed to calculate the relative position of the constituent body parts. Finally, a scoring system is constructed to carry out the classification of four strokes, including butterfly, backstroke, breast stroke, and freestyle. Experimental results demonstrate the validity and efficiency of our proposed approach.

Consistência e variabilidade do nado crawl em indivíduos habilidosos / Consistency and variability in the crawl swim of skillful individuals

Silva, Caio Graco Simoni da 20 March 2008 (has links)
Ao observar os movimentos de indivíduos habilidosos praticando esporte, supõe-se que estes sejam a repetição de uma série de movimentos idênticos. Mas, o que no comportamento motor habilidoso parece idêntico a partir de uma observação geral, macroscópica, quando observado em detalhes, apresenta variabilidade. O comportamento motor habilidoso apresenta aspectos invariantes que resultam em um padrão característico da habilidade praticada (consistência) e também aspectos variantes, quando fatores microscópicos são focalizados. Assim qualquer tentativa de compreender o comportamento motor habilidoso deve considerar consistência e variabilidade como características complementares. No entanto, os poucos estudos de natação que consideraram estas características tiveram crianças como participantes. O objetivo do presente estudo foi investigar a consistência e a variabilidade da braçada do nado crawl em indivíduos habilidosos. Participaram 16 nadadores, todos voluntários, do sexo masculino, com média de idade de 20 anos. Destes, 8 com índice para disputar campeonatos nacionais e 8 com índice para participarem de campeonatos estaduais. Todos nadaram 2 x 50 metros em cada uma das três condições, ou seja, a 80%, 90% e 100% da velocidade máxima individual. Para fins de análise foram utilizadas medidas antropométricas, de desempenho global e de organização temporal, estas últimas correspondentes a macro e a microestrutura da braçada. Não foram detectadas diferenças entre os nadadores dos grupos Nacional e Estadual nas medidas antropométricas, mas os do grupo Nacional foram mais velozes nas condições 100% e 90%. O grupo Nacional, ao contrário do Estadual, manteve a macroestrutura da braçada nas três condições, e na condição de 80%, apresentou maior variabilidade nas medidas correspondentes a microestrutura que o grupo Estadual. Em conjunto, os resultados permitem concluir que o grupo Nacional é mais habilidoso que o Estadual desempenho e que adaptou seu comportamento a partir da redundância do sistema, enquanto o Estadual o fez a partir da modificação da estrutura / When observing the movements of skillful individuals practicing sport, one might suppose that they are a repetition of a series of identical movements. However, what seems to be identical in a skillful motor behavior from a general macroscopic view, is, in fact, variable when observed in detail. Skillful motor behavior presents invariant aspects that result in a particular pattern of the skill (consistency), but shows variant aspects, when microscopic factors are focused. Thus, any attempt to understand skillful motor behavior should consider consistency and variability as complementary features. However, the few studies of swimming that considered those features had children as participants. The aim of this study was to investigate consistency and variability in the crawl stroke of skillful individuals. Participants were 16 male volunteer swimmers with a mean age of 20 years. Eight with ranking to participate in national championships and eigth with ranking to participate in state championships. All swam 2 x 50 meters in each of three conditions, 80%, 90% and 100% of the individual maximum speed. For analisys purpose, antropometric, performance and temporal organization measures were employed, the last ones in correspondence to strokes macro and microstructures. On the antropometric measures no difference were detected between National and State groups but the National group was faster at 100% and 90% conditions. The National group, contrarily to State group, maintained stroke macrostructure within the three conditions and at the 80% condition, showed more variability on the the microstructure measures than the State group. Summing up, results lead to the conclusion that the National group is more skilled than the State group performance and that adapted his behavior do system redundancy while the State group did it through structure modification
