Protocolos de natação em modelos experimentais com ratos

Exercise physiology has attempted to reproduce the experimental exercise in the laboratory using mainly rats. The swimming exercise has emerged as one of the leading research in these type ergometers. Thus, this research consisted of a literature review addressing the key issues which involve the exercise of swimming in the model rats. Training of aerobic and anaerobic swimming, evaluation models and models of periodization were the topics suggested in this research. In several studies, models of aerobic and anaerobic training have been proposed with the aim of studying their effect on normal and abnormal physiological parameters. However, earlier studies lacked methods of analysis aiming to determine the exercise intensity in the animal model. For this reason, in the last decade, assessment models have been adapted for humans to animals, especially rats. The maximal lactate steady state (MLSS) and lactate minimum (LM) are among the various techniques used to measure the amount of effort produced by swimming exercise in rats. Thereafter, based on biochemical parameters such as lactate, swimming exercise in rats has become the highest-rated, ie, using as reference the anaerobic threshold (AT). In another aspect, an entirely new line of research has tried to understand and promising swimming training in a periodized and its effects on some biochemical parameters. But this is an area little researched so far. Thus, the experimental model of swimming has proved an important resource of exercise physiology. From this model, it becomes possible to study the exercise, especially swimming, in more accurate, based on invasive and incisive analysis of the rat

Efeito da utilização do coringa no treinamento em campo reduzido em jogadores de futebol universitário

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

O nível de esforço físico durante o treinamento coletivo no Futsal na categoria Sub 13

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...

A pedagogia do jogo no contexto escolar

As the ludic taking the second place at school environment, on account of logical and rational activities and the excessive charge of a professional achievement of children by society and, also, the own family, the school doesn't become a pleasant ambient of frequenting. This study wants to understand, in a better way, the utilization of ludic activities as a pedagogic support into the learning and the development of the cognitive, emotional and creative potentiality of children in different education system (public and private) of Ibitinga-SP. It also investigates the docent attitude and practice during the ludic activities and its repercussion in the students' performances when introduced. The bibliographic researches present that the utilization of games, as a pedagogic resource, contributes to the learning process and to the human development of the students from the first cycle of the Elementary School. The School has to rescue the desire of learning, which is playing, the most natural way. The research's target audience are teachers from the Ciclo I of the elementary school and the focus is the utilization of the ludic into the different areas of teaching, considering the context that the schools are embedded. The reality observation, which enables a straight contact with the researcher and the study object, helped out with the issue comprehension. It was possible to identify that the utilization of ludic activities as a pedagogic strategy does not happen just because of knowledge absent, but also because of the submission to many goals imposed by the education system and/or by the didactic materials used, which don't have any worry to valorize the period of develop that the students are living, filtering out some characteristics from the phase that contributed to the learning. The responsibility to create a new signification to their social function is from the education system and the school that works with it. To the...

A influência da música nas atividades físicas e sua impressão no corpo e nos estados de ânimo

Numerous studies in physical education and music's area have been conducted to improve the quality of life and health of people, all of them under physiological, psychological and social fields. Thus, when properly analyzed, both Areas are connected, because the movement itself, main subject of physical education, has a close proximity to the rhythm, an essential element of music. That's why it is important to discover the benefits of this relationship, because, in many of its practices, physical education makes use of music, for example, in aerobic gymnastic and dance classes. As a consequence, this study aims to investigate, through literature, the influence of music in physical activities and its imprinting in the states of mind and body of practitioners, as well as clarify the criteria for choice of songs that are used in such practice. This research occurred under literary explore, done through theoretical analysis of the thematic. At first place, a contextualization of the auditory system and its relationship with the music and the perception of sound were made, then the main theme was explored. The music, even before generate and influence motor and psychic movements in the human body, is already moving in space, because it is formed through vibrations of molecules. It is decoded first as a movement from the ears, and then decoded as sound, when in the brain. It is important to worry about sounds at high intensities and also with those which are outside the hearing thresholds within physical activities involving music, because they may be harmful to health and also to states of mind. As far as music and movement is concerned, they are closely linked, and the human being has an instinctive sense of rhythm that can be seen when listening to music, because the motor cortex is also activated. Therefore, it is important to work the sound and body movement together, because in practice they are inseparable and they contribute greatly to...

Prevalência de hipertensão arterial em adolescentes escolares em Ibitinga: importância do histórico familiar

Hypertension (H) affects approximately 1,2 billion of people in the world. Among the main risk factors are weight excess, sedentary lifestyle, socio economic condition and family history of H. The main aim of this study was to assess the prevalence of hypertension in teenager scholars in Ibitinga, finding the role of family history of H and to correlates these results with nutritional condition, anthropometric variables and socio economic condition. This research analyzed 150 participants (50 teenager students and their parents) in public and private schools. All the volunteers had their weight (kg) and height (m) measured to calculate the body mass index (BMI). The students were classifieds from table of percentile of obesity (Centers for Disease Control and Prevention, CDC). The blood pressure (BP) was evaluated according to V Arterial Hypertension Brazilian Guidelines (VAHBG, 2006). The high values considered of BP were: ≥140x90 mmHg for adults and percentile >95 for teenagers. The socio economic condition was categorized from IBGE. Among the students, 36% had high BP and 20% borderline. The percentage of high BP were bigger in the public (44%) than private schools (28%), showing a negative correlation between socio economic condition and systolic BP (SBP, r=0.2857) and diastolic BP (DBP, r=0,0165). The prevalence of elevated BP was higher in the girls of public schools (47% vs 40% boys) and in the boys at the private schools (33% v s23%). Weight excess was present in 42% of children (12% obesity and 30% overweight). Again, public schools had prevalence of obesity (52% vs 3% in the private) which was not correlated with socio economic condition. Percentage of overweight and obesity were bigger in the girls of both public (54% vs 50% boys) and private (38% vs 25%) schools. Among the students with H, 67% were overweight. Elevated BP was found in 54% of the fathers and 32% of the mothers. With respect to nutritional condition, 56% of the...

A complexidade de tarefas de controle postural afeta a sensibilidade háptica proporcionada pelo toque leve?

A utilização de pistas hápticas para a estabilização da postura através do toque vem sendo apontada como uma eficiente fonte de informação sensorial que conecta o indivíduo ao meio. Dessa forma, o paradigma do toque leve (i.e., tocar uma superfície com força inferior a 1 Newton) é uma das possibilidades de, através do contato com determinada superfície, atenuar as oscilações do indivíduo. Sendo assim, o objetivo deste estudo foi verificar a eficiência do toque leve em tarefas de alta complexidade ao equilíbrio e, concomitantemente, analisar a relação entre percepção háptica e controle da postura. Para isso, 15 adultos jovens saudáveis participaram deste estudo, permanecendo em pé na posição tandem sobre uma plataforma de força e-nas condições pertinentes-sobre uma trave de equilíbrio. As condições deste estudo variaram entre a utilização ou não do toque, a utilização ou não da visão, e ainda, permanecer em pé sobre uma superfície de altura normal (0 cm) ou uma superfície com elevação (20 cm). Através da análise estatística avaliamos as variáveis amplitude média de oscilação (ântero-posterior e mediolateral), velocidade média (ântero-posterior e medio-lateral) e a trajetória total. Nossos resultados demonstraram, como já era esperado, um aumento significativo da oscilação corporal nas condições sem toque e sem a utilização da visão, e ainda maior quando houve elevação da superfície de apoio dos pés. Entretanto, quando o toque leve foi utilizado nessas mesmas condições houve uma redução significativa da oscilação postural dos indivíduos. Dessa forma, concluímos que mesmo em tarefas de alta instabilidade ao equilíbrio, o toque leve continua auxiliando no controle da postura

According to the literature studied approach the position of women within football, recall some historical facts as well as girls are seen within football in the school environment, where we can cite the difficulties that teachers still have mixed classes when they are given within physical education, making seek alternatives to the practice of team sports, focusing on football practice

As novas tecnologias de informação e comunicação como um recurso para a produção de material didático voltado ao ensino do atletismo

Apesar da importância do atletismo, ainda são vários os problemas enfrentados por aqueles que se dedicam a ensiná-lo. Procurando estratégias que contribuam para sanar algumas dessas dificuldades, essa pesquisa teve como objetivo identificar as Novas Tecnologias de Informação e Comunicação (NTIC), em especial, a internet, como forma de subsidiar o ensino do atletismo em aulas de Educação Física. Para atingirmos o objetivo proposto, nos pautamos no desenvolvimento de quatro etapas, a saber: 1ª Etapa - pesquisa bibliográfica, em livros, artigos e websites, visando coletar materiais didáticos relacionados ao atletismo; 2ª Etapa - análise e divisão dos conteúdos da internet, em especial, dos vídeos do Youtube, por possuírem diversos conteúdos relacionados ao atletismo; 3ª Etapa - organização do banco de dados, no formato de material didático, com base nos vídeos do Youtube, capaz de subsidiar o trabalho do professor de Educação Física na escola, com sugestões de atividades a fim de tornar as aulas sobre atletismo mais dinâmicas e numa linguagem cada vez mais frequente no dia a dia dos alunos

Aspectos psicopedagógicos da competição esportiva escolar

A escola é uma instituição qual a competição esta instalada intrinsecamente, e esta pedagogia se tornou atualmente muito controversa, pois esta gera diversas dúvidas para sua prática bem aplicada, e acaba, portanto, sendo simplesmente negada por diversos educadores. O fato é que a competição, como elemento fundamental do esporte, e, por sua vez, caracterizado dentro da cultura corporal, a faz elemento fundamental a ser executado dentro das aulas de Educação Física. Esta que passou historicamente por diferentes visões e vertentes, desde o militarismo até a utilização dos PCNs como principal ferramenta norteadora das aulas, tem estas mudanças temporalmente abruptas contribuintes para com a polarização veemente de opiniões acerca da competição esportiva na escola. O que acontece atualmente, seja por falta de preparo do professor, estudos sobre o assunto ou mesmo sobre essa constante negatória competitiva, faz com que ela seja erroneamente utilizada dentro das aulas de Educação Física e, uma ferramenta como esta, mal utilizada, acaba meramente espelhando os desportos perfomances de alto nível, onde se tem a vitória como principal foco ativo, o que acaba levando à exclusão de certos alunos menos habilidosos. Temos então de estudar esta potente ferramenta pedagógica que é a competição esportiva escolar, para que possamos utilizá-la de maneira correta, focando o processo educativo qual empreende esta competição e o desporto, se pautando em objetivos claros para que seja possível se obter uma competição com faces educativas fortes. Seria muito cômodo para nós educadores simplesmente ignorar esta face competitiva inerente à escola, inviabilizando, por conseguinte, um elemento rico e vasto de conteúdos e pedagogias em nossa área. Temos então de aceitar essa competição como um desafio, onde se estudam formas para recriá-la da melhor maneira pedagógica possível, se maximizando os efeitos benéficos desta...

Avaliação das variáveis técnicas no contexto esportivo

Assessment is a theme explored in various areas of human performance, particularly for the analysis of an athlete performance and/or all team members in game situation. Assessment requires different tests and models to quantify strengthens and weaknesses of an athlete and of the team. With that in hand, it is possible to develop an intervention program, with consequent improvement of techniques and tactics play systems. The present study aimed to identify, in the literature, the athlete's performance ratings and of the team in game situation for team sport. Based on the literature review, we propose a set of variables to include in an instrument for basketball performance assessment. The methodology for the present study involved a collection of materials, including scientific articles, books, websites, academic papers. The present research comprises the concepts and definitions related to: team sport; the relevance of game analysis and its development; the advantages and disadvantages of different assessment techniques, particularly in team sports; and lastly, the instruments used for assessment in the context of team sport athletes. From the literature review we propose a set of variables that may be useful to consider in an assessment instrument for basketball performance

Efeitos da música nos estados de ânimo durante a prática de ginástica laboral

O estilo de vida é a forma com que cada indivíduo conduz a suas atividades diárias, as quais refletirão diretamente na sua saúde. Dessa forma, a prática da ginastica laboral busca oferecer um novo espaço de qualidade de vida, saúde e lazer para o trabalhador. A música nas atividades físicas é utilizada no sentido de motivar a continuidade dos exercícios físicos ou de distrair o praticante de estímulos não prazerosos como cansaço, dor ou até tensão psicológica. Estudos afirmam que os estados de animo melhoram em consequência da atividade física. Sendo assim, o objetivo do trabalho será analisar os efeitos da música nos estados de ânimo de trabalhadores durante aulas de um programa de ginástica laboral. Para isso, este estudo contou com 20 participantes, de ambos os gêneros, funcionários da UNESP - diversos setores, localizada na Av. 24A, nº1515, Bela Vista, Rio Claro/SP, que realizam funções semelhantes em cada ambiente de trabalho. Como forma de avaliação foi utilizado um questionário de dados cadastrais, um questionário relacionado à preferência musical e uma lista referente aos estados de ânimo. Obtivemos como resultado que a prática de ginástica laboral pode ser significativa para os estados de ânimo de seus praticantes em situação sem música e ainda mais com a presença de música da preferencia dos participantes. Verificamos que só com a audição de músicas não trouxe alterações significativas nos estados de ânimo. Verificou-se que a união da música preferida com a atividade física é a situação que mais traz benefícios ao estado de ânimo do trabalhador. Portanto, concluímos que a música, quando do gosto do praticante, aliada a atividade física pode trazer benefícios emocionais significativos à prática de ginástica laboral no ambiente de trabalho

Grupo Ginástico UNESP: contribuições da Ginástica para Todos na formação de seus participantes

Gymnastics for all or General Gymnastics is a gymnastic body practice without competitive purposes, demonstrative character that combines the basics of gymnastics with different forms of body language. It is a pleasurable physical activity and inclusive, within the gymnastic possibilities offers great opportunities for participation of people, creativity, cooperation and human values experiences (AYOUB, 2003). Within this proposal is, in 2011, the Gymnastic Group UNESP, under the guidance and coordination of teachers Laurita Marconi Schiavon e Silvia Deustch as a project of university extension of the Department of Physical Education, Biosciences Institute of the São Paulo State University / Campus Rio Claro - SP. His working method and choreographic composition based on the proposal of the Gymnastic Group Unicamp, reference in this body practice in Brazil, and their course is in two parts: one for the exploration of all the resources that the teaching materials can provide and the other focused on social interaction of its participants. Therefore the research developed in this study aimed to verify contributions of the participation of members in Gymnastic Group Unesp vocational training thereof, and to verify the relationship and the approach of the members with Gym. The methodological approach adopted for this qualitative research is descriptive, and quantitative and qualitative data collected through questionnaires. The participants were 32 students from different courses at the University, and members of Gymnastic Unesp Group from 2011 to 2013, with the inclusion criteria: 1. minimum of one year of participation in Gymnastic Group Unesp; 2. Minimum of two performances of choreography in events with that group. Quantitative data are processed using descriptive statistics and qualitative analyzed by content analysis technique proposed by Laville and Dionne (1999). According to the results obtained over 41% of the participants had no...

Influência da violência no esporte sobre espectadores de MMA: análise de percepções e comportamentos

Modern society lives daily with groups of human beings who have high rates of aggression and violence. Scholars in the field point to the influence of certain environmental condition for the development of aggressive behavior. Among such circumstances, we can quote various aspects including the influence of media, and more specifically, the MMA (Mixed Martial Arts). The MMA is now one of the world's most popular sport, having international visibility through your largest organization, the UFC® (Ultimate Fighting Championship). The sport's global coverage is surely source of influence for our children and adolescents, who without the correct direction, can take the scenes seen in the sport as common facts of everyday life, making aggression and violence acceptable behaviors in their lives. Many studies show behavioral changes related to violent practices in virtue of exposure of individuals to aggression scenes by media. Works provide some interesting theoretical models to explain the observational learning. Under such aspects, the determined reality brings a need for in-depth studies on the subject addressed, looking for a better understanding of relations between the sport's violence and your influences on social behavior of individuals in this context, and then, look for possible solutions to deal with the problem pre supposed
