O futebol nos dias de hoje representa algo muito maior do que um exercício físico ou uma atividade de descontração. Ele desempenha um papel dentro da sociedade que extrapola as perspectivas do jogo. Reduzir a análise sobre o futebol profissional apenas ao aspecto lúdico do esporte também diminui a concepção sobre o que ele realmente representa. Nos bastidores do espetáculo futebolístico existe um universo de atos políticos que abrangem diversas esferas do poder que por sua vez auxiliam na execução do esporte como um evento esportivo com milhões de espectadores. Uma das razões para que o âmbito político do esporte seja menos conhecido do que as táticas dos técnicos ou dribles dos jogadores é a cobertura feita pelos meios de comunicação. No decorrer de sua existência, o futebol se transformou em um evento globalizado que envolve em sua órbita muito mais do que apenas o aspecto esportivo. Com os anos, o esporte foi se firmando em diversos países como produto cultural e até mesmo ferramenta política. O que se vê contudo é a sobreposição midiática do jogo sobre a sua verdadeira estrutura. O entretenimento trazido pelo esporte ganha as páginas enquanto o jogo político que sustenta a realização do mesmo recebe uma atenção mais discreta das mídias. A proposta deste trabalho é analisar como foi feita a divulgação de notícias referentes à Copa do Mundo de 2014, que será realizada no Brasil, nos jornais Folha de S.Paulo e O Estado de S. Paulo durante o ano de 2012 através dos seus cadernos de esportes. O objetivo é compreender qual é o teor e a intensidade da cobertura sobre os fatos políticos que ajudam a dar forma ao evento mais importante do futebol. Acontecimentos desta proporção exigem preparação do país, o que implica em um trabalho em conjunto entre o Governo Federal e FIFA. Pretende-se analisar a contextualização feita pelos jornais em relação ao esporte ao seu aspecto esportivo, podendo...

O presente trabalho busca trazer um olhar mais humano para a formação de jovens jogadores de futebol. A carreira é uma das mais almejadas pelas crianças em um país onde a educação primária ainda é deficitária. Soma-se isso à cultura enraizada na parte massiva da população de que estudar não é substancial. Deslumbrados pela fama e a importância dos jogadores profissionais, evidenciadas pela mídia esportiva e presentes na sociedade brasileira, estes garotos passam a buscar o mesmo para si, sem saber dos riscos e dificuldades que a carreira pode oferecer. Muitos deles esquecem-se da vida escolar e, caso não tenham sucesso na carreira profissional futebolística - o que acontece com a maioria, correm sérios riscos de ficarem marginalizados perante a sociedade. Este trabalho busca mostrar a visão de jovens que já estiveram envolvidos no universo das categorias de base do futebol e não prosseguiram no esporte, mas souberam priorizar os estudos e ter uma profissão alternativa. Mostra também depoimentos de profissionais que lidam com jovens que ainda alimentam esse sonho. Por último, traz notícias em geral do mundo do futebol de base

Swimming is a sport well suited to any age group, it worked properly when the individual stimuli that provides assist in human development. But water stimulation, is not something that is so easily in physical education in Brazil. Development corresponds to changes that occur throughout life, but that depends on the stimuli provided. Several studies have shown positive effects of swimming in relation to the child. This study aimed to verify if children swimmers and physical education classes have better motor development than those who do not practice the sport. Collection was done with two groups of 10 students between 9 and 11 years. As a group consisting of non-swimmers, and another formed by those that complement the physical education class with the regular practice of swimming. To develop the study was administered a battery of the proposed motor adapted Rosa Neto (2002) in which each child performed tasks corresponding to their chronological age (CA) and were only able to perform the task at a later age, when it was obtained successful in completing the task as originally proposed. At the end of the application of all statistical tests was done getting mean and standard deviation of the old motor (IM), calculated the ratio General Motor (MGQ) for the classification of the child's motor development and application of the t test with p <0.05 to observe the level of significance in the results. The results showed that the group swimmers had better agility tests which resulted in a difference between (IC) and (IM) higher compared with the non-practitioner. They also had higher average (MGQ), but these were not sufficient to classify the group into another level of development, however, by observing isolated cases, two children that practice would be a greater level of development. Through the t test was observed that the group swimmers had significant difference in balance ability. We conclude that the swimming group got positive overall...

Soccer is the most popular sport in Brazil and one of the most popular in the world. Within this context, the practice of university soccer has increased the number of practitioners. A methodology widely used in the training of high performance teams are games reduced field ( JCR). The objective of this study was to evaluate the intensity of physical effort of football players during a small side game, 4x4, check the correlation between [La], HR PSE and the players and the floater influence on the intensity of the small side game. We analyzed eight players of UNESP in Bauru mean age 21.2+1.5 years, weight 75.8+11.6 kg, height 1.77±8cm, body fat percentage 12.3+5.5%, VO2max 37.1 ml/kg/min. The training was performed in 4 x 6 min with an interval of between one minute for recovery. The [La] and PSE were collected between the second and third time and after the end of training, the HR was measured every five seconds throughout the training through the RS400 heart rate monitor. A training session player floater participation (4x4+1) and the other not (4x4). The results presented showed no correlation with the HR [La] and PSE. HR significantly different, being 157+10 in the game 4x4+1 and 146+13 in the game 4x4. The percentage of HRmax in the game with floater was 81.3% and 75.7% in the game without. The players were most of the time in a higher intensity in the JCR with a floater, 37.8% of playing time over 85% HRmax, and 22.5% of playing time over 85% of HRmax in the JCR without floater, demonstrating that the use of a floater player made the game more intense and efficient to increase the intensity of the game

Futsal is one of the most popular sports in Brazil, played on five continents, in hundreds of countries, but is still a poorly studied sports science. Among the types of training used in the preparation of soccer players, the collective training is one of the most used because it is a simulation game. The application of the training load is often made in large quantities (volume) with exercise duration and intensity greater than what the athlete can handle. Thus, this study aimed to evaluate the intensity of physical exertion of futsal players of basic category during collective training. We evaluated twenty (N=20) soccer players from two teams with different levels of training. There were ten players on a team federated (FED) and ten players on a team for a project extension (EXT). Samples were collected at the respective locations of training. An evaluation of anthropometric and during collective training heart rate was measured and at the end of each training time blood samples were collected for analysis of blood lactate concentration and perceived exertion of the players. There was significant difference between the two teams only in fat percentage (FED=13,4 e EXT=21,2). The average heart rate during training was 174 ± 12.2 bpm, which corresponds to 84% HRmax. There was significant difference between heart rate and the percentage of HRmax in the two parts of training in both teams. The Federated team players remained most of the time in more intense intensity zone (above 85% HRmax), while the EXT players were most of the time zone of moderate intensity (65-85% HRmax). The rating of perceived exertion (FED=3,5 e EXT=3,2) and blood lactate concentration (FED=2.4 mmol/L and EXT=2.9 mmol/L) showed no significant difference between the two teams and between the two times. During training there was a significant correlation (p= 0.71) between heart rate and lactate concentration. The collective training showed an intensity that is supposed to be...

Introduction: physical exercise has been recommended as a non-pharmacological, therapeutic strategy in the treatment of important cardiovascular risk factors. Objective: to analyze the impact of an exercise program, tailored to the reality of the Family Health Units (FHU), on body composition, cardiovascular risk factors and Framingham score in obese postmenopausal. Methods: 70 women between 50 and 79 years, sedentary, obese and without menstruating for at least twelve months, were randomly assigned to a trained group (TG) (n = 35) and an untrained (GnT) (n = 35). The GT took 20 weeks of a physical exercise program with three weekly sessions, consisting of monitoring activities and heating (10 minutes), 25 minutes of exercise flexibility and strength, 50 minute walk with intensity between 50-65% of VO2max and 5-minute cool-down. The GnT was instructed to maintain their normal activities. Results: TG showed significant reductions in body mass index (30,1+3,7 vs. 29,3+3,7; p=0,0001), waist circumference (93,3+10,3 vs. 89,1+10,4; p=0,0001), percentage of fat (54,2+2,9 vs. 53,2+3,3; p=0,0001), systolic blood pressure (128,0+14,6 vs. 119,2+10,3; p=0,0001), triglycerides (148,4+66,1 vs. 122,8+40,7; p=0,006), VLDL cholesterol (29,7+13,2 vs. 24,5+8,0; p=0,005) and Framingham score (13,08+4,0 vs. 11,77+4,1; p=0,010). In the untrained group were observed significant increases in the percentage of fat (55,0+4,0 vs. 57,0+3,8; p=0,0001), systolic blood pressure (128,6+10,5 vs. 133,7+12,0; p=0,001), fasting glucose (95,2+18,4 vs. 113,7+28,8; p=0,001) and Framingham score (12,82+3,2 vs. 13,91+4,0; p=0,043), but also decreases levels of HDL cholesterol (55,1+10,5 vs. 51,7+11,0; p=0,017). Conclusion: the exercise program, adapted to the conditions of FHU, was effective in reducing cardiovascular risk factors in obese postmenopausal women served by the SUS program.

Introduction: skeletal muscles are dynamic tissue that can change their phenotypic characteristics providing a better functional adaptation to different stimuli. L-thyroxine is a hormone produced by the thyroid gland and has been used as an experimental model for stimulation of oxidative stress in skeletal muscle. Coenzyme Q10 (CoQ10) is a fat-soluble provitamin endogenously synthesized and found naturally in foods such red meat, fish, cereals, broccoli and spinach. It has antioxidant properties and potential in the treatment of degenerative and neuromuscular diseases. Objective: to evaluate the protective effect of CoQ10 in the soleus muscle of rats against the oxidative damage caused by L-thyroxine. Methods: the rats were divided in four groups of six animals each: Group 1 (control); Group 2 (coenzyme Q10); Group 3 (L-thyroxine), and Group 4 coenzyme Q10 and L-thyroxine). After euthanasia, blood was collected and serum activity of the enzymes creatine kinase (CK) and aspartate aminotransferase (AST) was analyzed. In the soleus muscle homogenates the factors related to oxidative stress were assessed. Results: CoQ10 protected the soleus muscle against the damage caused by L-thyroxine and favored the maintenance of the antioxidant enzymes glutathione reductase and glutathione peroxidase, the concentration of decreased and oxidized glutathione, and prevented lipid peroxidation. Conclusion: the results indicate that CoQ10 protects rat soleus muscle from oxidative damage caused by L-thyroxine.

The present study has as its main purpose the investigation of teachers'view concerning the teaching and learning of basketball in Physical Education classes in a school setting. The selected teachers who participated in this survey come from public and private institutions in the city of Volta Redonda, RJ, Brazil, teaching 6th-9th grade classes of elementary school. This was a quantitative and qualitative study with content analysis. Data collection included interviewing 60 teachers who provided their opinions on the issue investigated. Development of basketball was investigated not only as a content for the Physical Education classes, but also as a dimension that goes beyond school boundaries, where that sport plays an important role in society. Joint actions to provide the opportunity for basketball to grow as a content for Physical Education classes may represent a way to describe its implementation in all contexts, although the importance of this discipline in the school setting should not be disregarded in favor of obtaining results in sports competitions.

Introduction: The rest interval between bouts is a crucial variable of resistance training to ensure recovery of neuromuscular capacity. Objective: To compare the effect of rest interval between repeated bouts of resistance training on neuromuscular capacity of trained men. Methods: Eight resistance-trained men (21.6 +/- 3.3 years, 75.1 +/- 11.3 kg, 178.2 +/- 6.8 cm) performed two randomized and crossover resistance exercise bouts, repeated with rest interval of 24h or 48h. The bouts consisted of horizontal, inclined and declined bench press performed with five sets of 10 repetitions with an intensity of 70% of one repetition maximum (1RM) for each exercise. Neuromuscular performance post-exercise bout (strength, power and speed), was assessed with an accelerometer (Myotest (R)), with a load of 50% 1RM, in the bench press exercise. Results: Both sessions (24 and 48h) showed significant reduction (P < 0.05) in the neuromuscular capacity (strength, power and speed) post-exercise bout, returning to baseline values within 24h (P> 0.05). Conclusion: The results suggest that the rest interval of 24h is sufficient for recovery of neuromuscular performance in upper limbs of resistance-trained men.

O atletismo, no Brasil, é um esporte pouco divulgado nas aulas de Educação Física. Vários são os motivos apontados para que isso ocorra: falta de material, deficiência de infraestrutura, falta de interesse dos alunos e ausência de um caráter lúdico no ensino das provas. Entretanto, o GEPPA, Grupo de Estudos Pedagógicos e Pesquisa em Atletismo, por meio da pesquisa e extensão universitária, tem se dedicado à difusão e estudo das inúmeras possibilidades de adequação e criação de oportunidades que envolvem seu ensino. Partindo dessa ideia, o grupo desenvolve o Projeto de Extensão Atletismo para Crianças e Jovens na cidade de Rio Claro, que tem, justamente, o intuito de divulgar o atletismo e proporcionar às crianças e jovens da comunidade um contato com essa modalidade esportiva. Constatando-se a eficácia desse Projeto de Extensão, desenvolvido na Unesp-RC, este Trabalho de Conclusão de Curso tem como objetivo: promover a pesquisa em torno do atletismo, a fim de evidenciar o panorama da extensão de atletismo no ambiente universitário brasileiro. Para atingir o objetivo proposto, foi desenvolvida uma revisão de literatura que em um primeiro momento abordará os principais problemas que cercam o ensino do atletismo, apontando o papel do profissional de Educação Física no seu ensino; aspectos relacionados à extensão universitária brasileira e à sua relação com o ensino e à pesquisa. Além disso, será realizada uma pesquisa exploratória na internet, em busca de materiais que poderão evidenciar a existência de projetos de extensão de atletismo oferecidos à comunidade, que serão descritos no trabalho a partir das informações coletadas. Com base nos resultados dessa pesquisa esperamos concentrar informações referentes a projetos destinados ao ensino do atletismo no Brasil, tomando como ponto de partida que esse tipo de trabalho de extensão universitária é importantíssimo para a difusão...
