That way alternatives which promote practice that increase level of scientific Literacy is a challenge (deal) for educators. Inclusion of practice that involve Astronomy is a strategy which can collaborate in this process, and having support Significant Learning theories. Following this idea, this project promote a diffusion of this manner of learning though practise in Physical class and Basic Education Science, as well practice of experiments involving basic astronomical tools, observation of astronomical phenomena, planetarium sections, presentations, participations in Astronomy and Astronautic Brazilian Olympiad, science fairs and confection of didactic material for Teaching Astronomy are some activities include on this project. The report of all activities realized in the classes of Physics was through knowledges brought by students after researches, elaboration of experiment and presentation in classroom, promotes interest and improves understanding about the studied phenomena. As Educational Product, was created a homepage containing all material developed in this work, such as script of the experiments and descriptions of the practical activities and observations realized, which will serve as methodological handle in diverse Learning contexts in Science. / A Alfabetiza??o Cient?fica ? um dos grandes desafios da contemporaneidade. Criar alternativas para a promo??o de pr?ticas que elevem o patamar do letramento cient?fico ? um desafio para os educadores. A inclus?o de atividades pr?ticas envolvendo a Astronomia ? uma estrat?gia que pode colaborar neste processo, tendo como base a Teoria da Aprendizagem Significativa. Neste sentido, este trabalho promoveu a difus?o desta pr?tica nas aulas de F?sica e Ci?ncias na educa??o b?sica, bem como a pr?tica de experimentos envolvendo a constru??o de instrumentos astron?micos b?sicos, observa??o de fen?menos astron?micos, exposi??es de planet?rio, semin?rios, participa??o na Olimp?ada Brasileira de Astronomia e Astron?utica e confec??o de material did?tico para o ensino de Astronomia. O relato das atividades realizadas nas aulas de F?sica a partir dos conhecimentos trazidos pelos estudantes ap?s pesquisa, elabora??o de experimento e apresenta??o em sala de aula, promove o interesse, e melhora a compreens?o dos fen?menos estudados. Como produto educacional foi constru?da uma homepage contendo o material desenvolvido neste trabalho, bem como o roteiro dos experimentos e descri??o das atividades pr?ticas e observacionais realizadas, para que possam servir como suporte metodol?gico em diversos contextos de aprendizagem em ci?ncias.

Faced with the essential need to have an informal teaching environment for the areas of physics, chemistry and science, the simulator is comparable to a desert mirage where the various areas of research can be explored synchronically using the various technological and scientific tools to stimulate the curiosity of young people to take an interest in science and from there, to develop a meaningful learning in relation to those who do not use informal environments. The moon trip simulator is the necessary instrument to fill these gaps, adding to the possibility of insertion of young people trained in simulators like this, to be integrated into the short and medium duration space travel crew, undoing all the frontiers of Science, in especially, Astrophysics. The simulator is composed of diverse environments that resemble those found in real spacecraft, equipped with materials necessary for the execution of didactic-pedagogical, physical and other experimental activities included in this study. The formation of a multiprofessional team is crucial for the planning and execution of the Project as well as obtaining the positive results. / VIAGEM ?

Historically, the enphasis on the body had been related to inferior and less valorized topics while intelectual subjects had been considered superior. With the Lei de Diretrizes e Bases da Educa??o Nacional , from 1996, people can see an educational advance for the physical education, which is now considered a curricular component, as the other subjects, it s not seen as an extracurricular subject anymore. Inside this new conception, the phisical education has been through important changes which have influenced the pedagogical practices and the way teachers see the area ant its practice. This is a qualitative research, with field investigation, interviewing four public physical education teachers who have different years of experience in the area. Dates were colected through interviews, evolving a great interaction among researcher and teachers. This procedure is based on some steps, recurrent interviews and transcriptions and the categorization of the dates after each of them. The subjects participate completing, changing and explaining information. The results allowed us to realize that the changes occurred in the physical education area, in the view of the interviewed teachers, can influence students in their initial formation, going through the workplace conditions and the way pedagogical practice is organized, as well as that they can influence the valorization of the subject and its teacher. / Esta pesquisa tem como quest?o central investigar de que maneira as mudan?as ocorridas na ?rea da educa??o f?sica v?m marcando a concep??o do professor e a sua pr?tica pedag?gica.

Research problems were jointly constructed between actors and social and directed to answer the following questions authors: what are the phenomena that influence or influenced the construction of the conception of sport stakeholders and social actors involved in the PEAC? As the PEAC in its relations involving their intervention (action research), takes a critical-reflexive appropriation of knowledge and experience of the body in culture / with sports? There PEAC contribution in sports training and civic education of the students enrolled in the School of Sport this program? A significant contribution of the PEAC, in order to allow for social change in reality in the context where the program was implemented? To answers these questions, the study proposed a critical perspective, however, without making epistemic entrenchments, using contributions of theoretical frameworks in the field of Physical Education to discuss about physical culture and sport, in addition to the discussion of university extension. The analysis of data extracted from statements made by the subjects involved in the actions of the program (families, students, teachers and scholars of the program) were tabulated, organized and described using the technique of the Collective Subject Discourse. The main results of this Action Research highlights are proposing to reorganize the teaching (and learning as a result of) the sport in higher education and in social projects, a critical perspective, using various bodily expressive possibilities in an integrative action capable of initiating paradigm shifts in educational arenas, proposing social change in reality where social actors and authors are entered and recognizing the limitations regarding the extent of the changes. Furthermore, experiments with the PEAC, especially the Sports School project , which brought elements propose disruptions and contributions in micro dimensions ( sport , physical education and his theories) and macrostructural (model of society, public policy and extension), both permanently interconnected . / Este estudo foi uma Pesquisa-A??o que envolveu uma a??o de extens?o, o Programa Encaminhar: A??o Cidad?

Os problemas de investiga??o foram constru?dos conjuntamente entre os atores e autores sociais e direcionados a responder os seguintes questionamentos: quais os fen?menos que influenciam ou influenciaram a constru??o da concep??o de esporte dos atores e autores sociais envolvidos no PEAC? Como o PEAC, em suas rela??es que envolveram a sua interven??o (pesquisa e a??o), prop?e uma viv?ncia e apropria??o cr?tica-reflexiva dos saberes da cultura corporal no/com o esporte? Qual a contribui??o do PEAC na forma??o esportiva e cidad? dos alunos matriculados na Escola de Esporte deste programa? Existe contribui??o significativa do PEAC, no sentido de possibilitar para a transforma??o social na realidade no contexto onde foi implementado o Programa? Para as respostas estas quest?es o estudo prop?s, numa perspectiva cr?tica, contudo, sem fazer entrincheiramentos epistemol?gicos, utilizar contribui??es de referenciais te?ricos da ?rea da Educa??o F?sica que discuti sobre cultura corporal e esporte, al?m da discuss?o sobre a extens?o universit?ria. A an?lise dos dados extra?dos de depoimentos produzidos pelos sujeitos envolvidos nas a??es do programa (familiares, alunos, professores e bolsistas do programa) foram tabulados, organizados e descritos utilizando a t?cnica do Discurso do Sujeito Coletivo. Como principais resultados desta Pesquisa-A??o destacam-se a proposi??o em reorganizar o ensino (e como consequ?ncia o aprendizado) do esporte no ensino superior e em projetos sociais, numa perspectiva cr?tica, utilizando diversas possibilidades corporais expressivas, em uma a??o integradora capaz de iniciar mudan?as de paradigmas em espa?os de forma??o, propondo transforma??o social na realidade onde os atores e autores sociais est?o inseridos e reconhecendo as limita??es no que diz respeito a amplitude das mudan?as. Al?m disto, as experi?ncias com o PEAC, especialmente o projeto Escola de Esportes, trouxeram elementos que prop?em rupturas e contribui??es em dimens?es micro (conceitos sobre o esporte e suas rela??es com as teorias e pr?ticas da Educa??o F?sica) e macroestruturais (modelo de sociedade, pol?tica p?blica e a extens?o), ambas, permanentemente interconectadas.

In a parallel discussion, computerized psychological instruments, for a hand, reflects the development of information technology and your applicability to other areas, but also shows little advance for Psychological Assessment. In this perspective, this study aims to adapt the Exercise Dependence Scale (EDS-R) in two formats (paper-and-pencil and computerized) and evaluate evidence of factorial and convergent validity, and reliability of each version and compare them with each other. It is also proposed to observe the relationship of some bio-demographic (Sex, age, frequency, duration and intensity of practice exercise) and the exercise dependence (DEF). For this purpose, 709 regular physical activity practitioners, selected by procedures non-probabilistic sampling, responded a adapted version of EDS-R, Muscle Appearance Satisfaction Scale (MASS), Body Modification Scale (BMS) and a demographic questionnaire, analyzed through Exploratory Factor Analysis, Cronbach's Alpha and not parametric tests. Both the traditional version and the computer showed a seven factors structure, explaining 57 and 62% of the variance, respectively, and Cronbach's alphas of 0.83 and 0.89. Factors were: (1) intentionality, (2) continuity, (3) tolerance, (4) reduction of other activities, (5) lack of control, (6) abstinence and (7) time spent on exercise. Relationships were observed between the Exercise Dependence and the variables: age, diets, consumption of food supplements and medicines for weight change, desire to do plastic surgery and body satisfaction. We observed also a positive correlation between the DEF and the frequency, duration and intensity of exercise, and the factor "Dependence on exercising" from MASS, indicating convergent validity of the EDS-R. Finally, comparisons between the two formats were equivalent, with few changes: computerized version achieved higher DEF scores. Based on these results, it can be concluded that the EDS-R has factorial and convergent validity, reliability, to measure exerceise dependence on traditional e computerized formats. DEF is related to actions used to body modification and behaviors toward exercise. Finally, it was found equivalence between the formats, especially in psychometric parameters, thus suggesting feasibility of a computerized assessment. However, it was observed that the computerized data has sample recruiting strategies more limited / Embora traga benef?cios f?sicos e psicol?gicos, a pr?tica excessiva de atividade f?sica poderia ser ou desencadear um comportamento compulsivo, tornando o indiv?duo dependente deste. Em uma discuss?o paralela, cita-se a informatiza??o de instrumentos de medida em Psicologia, que se, por um lado, reflete o pleno desenvolvimento da inform?tica e aplicabilidade desta para outras ?reas, por outro evidencia tamb?m paradoxalmente pouco avan?o da mesma no campo da Avalia??o Psicol?gica. Nesta perspectiva, o presente estudo visa adaptar para o contexto nacional a Escala de Depend?ncia de Exerc?cio (EDS-R), em duas vers?es (papel-e-l?pis e informatizada), bem como verificar evid?ncias de validade fatorial, convergente e consist?ncia interna de cada vers?o e compar?-las entre si. Prop?e-se, ainda, a observar a rela??o de algumas vari?veis bio-demogr?ficas (g?nero, idade, frequ?ncia, dura??o e intensidade com que pratica exerc?cio) na depend?ncia de exerc?cio f?sico (DEF). Para tanto, 709 praticantes de atividade f?sica regular, selecionados por procedimentos de amostragem n?o-probabil?stica e acidental, responderam a vers?o adaptada da EDS-R, a Escala de Satisfa??o com a Apar?ncia Muscular (MASS), a Escala de Modifica??o Corporal (BMS) e question?rio s?cio-bio-demogr?fico, analisados por meio de An?lise Fatorial Explorat?ria, c?lculo do Alfa de Cronbach e testes inferenciais n?o param?tricos. Tanto a vers?o tradicional como a informatizada apresentaram uma estrutura de sete fatores, explicando 57 e 62% da vari?ncia compartilhada, respectivamente, assim como Alfas de Cronbach de 0,83 e 0,89. Os fatores foram: (1) intencionalidade, (2) continuidade, (3) toler?ncia, (4) redu??o de outras atividades, (5) falta de controle, (6) abstin?ncia e (7) tempo gasto em exerc?cio. Foram observadas rela??es positivas entre a Depend?ncia de Exerc?cio e as vari?veis idade, pr?tica de dietas, consumo de suplementos alimentares e medicamentos para altera??o de massa corporal, desejo de fazer cirurgia pl?stica e satisfa??o corporal. Observou-se, ainda, uma correla??o positiva entre a DEF e a frequ?ncia, dura??o e intensidade com que se pratica exerc?cio, bem como com o fator Depend?ncia em malhar da MASS, indicando, assim, validade convergente da EDS-R. Por fim, quanto ?s compara??es entre as duas vers?es de coleta, estas foram equivalentes, com poucas altera??es, tendo a vers?o informatizada atingido escores mais elevados de DEF. Com base em tais resultados, pode-se concluir que a EDS-R apresenta evid?ncias de validade fatorial, convergente e consist?ncia interna para identifica??o da Depend?ncia de exerc?cio f?sico nas vers?es tradicional e informatizada, bem como est? relacionada a a??es empregadas para modifica??o corporal e comportamentos voltados para o exerc?cio. Por fim, constatou-se uma equival?ncia entre as vers?es tradicional e informatizada, sobretudo nos par?metros psicom?tricos estrutura fatorial e ?ndices de consist?ncia interna, sugerindo, portanto, uma viabilidade de avalia??es informatizadas. No entanto, observou-se que a coleta informatizada possui estrat?gias de recrutamento um pouco mais limitadas

To perform these investigations, we followed a theoretical foundation supported by theories of transformative education in society, understanding the school as a mediating body, which through its pedagogical action could establish relations of reciprocity between individuals and society, discuss the reality and work social contradictions in order to modify them. Participated in this study 65 students and 03 teachers from the "Instituto Federal Fluminense - Campus Bom Jesus" and "Col?gio Estadual Rei Alberto I". We aimed as an object of this study the analysis of Physical Education practice in the institutions of vocational agricultural high school in the State of Rio de Janeiro from the perspective of a transformative education. We used a methodology with a qualitative approach with an exploratory, seeking an understanding of the society reality. Data were collected through questionnaires with closed questions, because this instrument allows to reach quickly and simultaneously more people; to ease some of the same disadvantages, we used an opening question. By applying the questionnaires, we had as a goal get information that raised some questions in theoretical foundation, which was worked on content in physical education classes, the perception of the body, the activities worked in the classroom, the teacher's role and the perception of physical education in relation to other disciplines present in the school curriculum. The results we got were that the prospects of education that most often appear in the speeches of the subjects included in the survey are linked to liberal education theories, that act to enhance and / or maintaining the existing society. We also identified that when we cross the information from questionnaire responses of teachers with the students, there are some variations, showing that not always the goals of teachers are perceived and affected the way they plan. The prospect of Physical Education Transforming appeared only in the speeches of teachers, showing that there is an attempt by them to develop an awareness of further work by the students, making them more involved in the exercise of a social practice conscious and less alienating. Regarding the perception of physical education in relation to other disciplines present in the school curriculum, the view of survey is positive, understanding the physical education as a discipline that conveys relevant content and contributes to the formation of critical students. We conclude our survey, with the certainty that investigating this issue goes beyond that, explaining that we did not intend just to answer questions that deserve a constant critical review, but we seek to indicate some ways, that in the future deserve to be taken up in other studies / Esta pesquisa procurou investigar a contribui??o da Educa??o F?sica Escolar para o ensino profissional agr?cola de n?vel m?dio. Para realizarmos essas investiga??es, buscamos uma fundamenta??o te?rica sustentada pelas teorias da educa??o transformadoras da sociedade, entendendo a escola como uma inst?ncia mediadora, que por meio de sua a??o pedag?gica pode estabelecer rela??es de reciprocidade entre os indiv?duos e a sociedade, podendo problematizar a realidade e trabalhar as contradi??es sociais, para modific?-las. Participaram dessa pesquisa 65 estudantes e 03 docentes, do Instituto Federal Fluminense ? Campus Bom Jesus e do Col?gio Estadual Rei Alberto I. Tivemos como objetivo desse estudo analisar a pr?tica da disciplina Educa??o F?sica nas institui??es de ensino profissional agr?cola de n?vel m?dio do Estado do Rio de Janeiro sob a ?tica de uma educa??o transformadora. Para isso, utilizamos uma metodologia com abordagem qualitativa, com uma pesquisa explorat?ria, buscando uma compreens?o da realidade vivida socialmente. Os dados foram coletados por meio de question?rios com perguntas fechadas, pelo fato desse instrumento permitir alcan?ar de forma r?pida e simult?nea mais pessoas; para amenizar algumas desvantagens do mesmo, utilizamos uma pergunta aberta. Ao aplicarmos os question?rios, tivemos como meta, levantar informa??es de alguns questionamentos que levantamos na fundamenta??o te?rica, que foi sobre os conte?dos trabalhados nas aulas de Educa??o F?sica; a percep??o sobre o corpo; as atividades trabalhadas na sala de aula; o papel do professor e a percep??o da Educa??o F?sica em rela??o ?s outras disciplinas presentes no curr?culo escolar. Os resultados que chegamos foram que as perspectivas de educa??o que mais aparecem nos discursos dos sujeitos inclu?dos na pesquisa, s?o as ligadas ?s teorias liberais da educa??o, que atuam de forma a aprimorar e/ou manter a sociedade vigente. Identificamos tamb?m que quando cruzamos as informa??es das respostas dos question?rios dos docentes com as dos discentes, h? algumas varia??es, mostrando que nem sempre os objetivos dos professores s?o percebidos e atingidos da maneira que eles planejam. A perspectiva de Educa??o F?sica Transformadora apareceu apenas nos discursos dos professores, mostrando que h? uma tentativa por parte deles de desenvolverem um trabalho de aprofundamento das consci?ncias dos estudantes, tornando-os mais participativos no exerc?cio de uma pr?tica social consciente e menos alienante. Quanto ? percep??o da Educa??o F?sica em rela??o ?s demais disciplinas presentes no curr?culo escolar, a vis?o dos participantes da pesquisa ? positiva, entendendo a Educa??o F?sica como uma disciplina que transmite conte?dos relevantes e contribui para a forma??o cr?tica dos estudantes. Conclu?mos nossa pesquisa, com a certeza de que essa tem?tica investigada n?o se esgota aqui, esclarecendo que n?o tivemos a pretens?o de responder quest?es que merecem uma constante revis?o cr?tica; apenas, buscamos indicar alguns caminhos, que futuramente mere?am ser retomados em outras pesquisas

Thus, this study aimed to evaluate the effect of an interdisciplinary intervention with a motivational approach on exercise capacity and habitual physical activity levels in overweight and obese adolescents. This is a randomized controlled trial with single blinding of individuals. Adolescents aged 15 to 18 years and body mass index (BMI) compatible with overweight or obesity (? 85th percentile and ?99.9th percentile) were included. The present study was approved by the Research Ethics Committee of the University (CAAE: 36209814.6.0000.5336) and all parents and/or guardians signed the informed consent form (ICF) and the students signed the assent form (AF). After the initial interest, individuals were invited by telephone to participate in a screening and then randomized through the Random Allocation Software (version 2.0) to participate in one of the following two groups: traditional approach (control) or motivational interview (intervention) aiming at the modification of lifestyle. In the control group (GC) the focus was the development of skills through educational health actions using the transmission pedagogy. In the intervention group (GI) the Transtheoric Model of Change was used along with the Motivational Interview to try to develop skills through educational actions in health that provided the development of autonomy and empowerment for behavior change, based on interdisciplinary motivational strategies. Subsequently, the initial evaluations, including the cardiopulmonary exercise test (CPET) and the levels of physical activity were assessed using a short questionnaire and an objective measure (pedometer). The evaluations were performed in two moments for both groups, at time zero (time of inclusion in the study) and after three months (end of intervention). Of a total of 43 overweight and obese adolescents, 05 were excluded, resulting in a sample of 37 participants, 18 in the GC and 19 in the GI. The mean age was around 17 years, with a predominance of females. The mean BMI (z score) was about 2, with 17 being overweight and 20 being obese. There were no significant differences in the baseline demographic, anthropometric and physical activity characteristics between groups. The motivational intervention did not cause significant differences (p>0.05) in the comparison of the variables of exercise capacity and habitual physical activity (questionnaire and pedometer) between GC and GI. The mean VO2max (mL/kg/min) at peak exercise was about 26.0, while the VO2max (mL/kg/min) at the anaerobic threshold (LA) was close to 22.0. All cardiovascular, metabolic, ventilatory and subjective variables at peak exercise were similar in both groups, except for Vmax that was significantly higher (p=0.001) in GI compared to GC. When we tested the effect of the motivational interview on nutritional status (weight and BMI) and physical fitness assessed by CPET (VEmax, VO2max, VO2max in AT and ventilatory equivalents) again no significant changes were observed. The results allow us to conclude that the intervention with a motivational approach did not alter physical fitness and habitual physical activity levels in overweight and obese adolescents. / A obesidade ? uma doen?a cr?nica crescente mundialmente e, em decorr?ncia da sua abrang?ncia, vem configurando-se quase como uma epidemia e tornando-se um dos problemas mais relevantes de sa?de p?blica na atualidade, uma vez que ? um fator de risco que pode desencadear diversas doen?as. Assim, este estudo teve como objetivo avaliar o efeito da interven??o interdisciplinar com abordagem motivacional sobre a capacidade de exerc?cio e o n?vel de atividade f?sica di?ria em adolescentes com sobrepeso e obesidade. Este estudo trata-se de um ensaio cl?nico controlado, randomizado, com cegamento ?nico dos indiv?duos. Foram inclu?dos adolescentes com idade entre 15 e 18 anos e ?ndice de massa corporal (IMC) compat?vel com sobrepeso ou obesidade (? percentil 85 e ? percentil 99,9). O presente estudo foi aprovado pelo Comit? de ?tica em Pesquisa da Universidade (CAAE: 36209814.6.0000.5336) e todos os pais e/ou respons?veis assinaram o termo de consentimento livre e esclarecido (TCLE) e os escolares o termo de assentimento (TA). Ap?s o interesse inicial, os indiv?duos foram convidados por telefone para participar de uma triagem e ap?s randomizados atrav?s do software Random Allocation Software (vers?o 2.0) para participar de um dos dois grupos a seguir: abordagem tradicional (controle) ou entrevista motivacional (interven??o) visando ? modifica??o do estilo de vida. No grupo controle (GC) o foco foi o desenvolvimento de habilidades por meio de a??es educativas em sa?de utilizando a pedagogia da transmiss?o. No grupo interven??o (GI) foi utilizado o Modelo Transte?rico de Mudan?a juntamente com a Entrevista Motivacional para tentar desenvolver habilidades por meio de a??es educativas em sa?de que proporcionassem o desenvolvimento da autonomia e do empoderamento para a mudan?a de comportamento, com base em estrat?gias motivacionais interdisciplinares. Posteriormente, foram agendadas as avalia??es iniciais que inclu?ram o teste de exerc?cio cardiopulmonar (TECP) e a aferi??o do n?vel de atividade f?sica habitual por meio de um question?rio curto e de uma medida objetiva (ped?metro). As avalia??es foram realizadas em dois momentos para ambos os grupos, no tempo zero (momento da inclus?o no estudo) e ap?s tr?s meses (t?rmino da interven??o). De um total de 43 adolescentes com sobrepeso e obesidade, 05 foram exclu?dos, resultando em uma amostra de 37 participantes, sendo 18 no GC e 19 no GI. A m?dia de idade foi em torno de 17 anos, com predom?nio do sexo feminino. A m?dia do IMC (escore-z) foi cerca de 2, sendo 17 classificados com sobrepeso e 20 com obesidade. N?o houve diferen?as significativas nos dados basais de caracter?sticas demogr?ficas, antropom?tricas e de atividade f?sica habitual entre os grupos. A interven??o motivacional n?o provocou diferen?as significativas (p>0,05) na compara??o das vari?veis de capacidade de exerc?cio e atividade f?sica habitual (question?rio e ped?metro) entre o GC e o GI. A m?dia do VO2m?x (mL/kg/min) no pico do exerc?cio foi cerca de 26,0, enquanto o VO2m?x (mL/kg/min) no limiar anaer?bico (LA) foi perto de 22,0. Todas as vari?veis cardiovasculares, metab?licas, ventilat?rias e subjetivas no pico do exerc?cio foram semelhantes em ambos os grupos, com exce??o da VEm?x que foi significativamente maior (p=0,001) no GI em compara??o ao GC. Quando se testou o efeito da entrevista motivacional sobre o estado nutricional (peso e IMC) e a aptid?o f?sica avaliada pelo TECP (VEm?x, VO2m?x, VO2m?x no LA e os equivalentes ventilat?rios) novamente n?o foram observadas altera??es significativas. Os resultados permitem concluir que a interven??o com abordagem motivacional n?o alterou a aptid?o f?sica e os n?veis de atividade f?sica habituais em adolescentes com sobrepeso e obesidade.

Athletes re usually mantain bodyweight above the limit of category and pratice rapid wight loss for the weight-in moment, with subsequent weight regain until the moment of the combat. Therefore, the aim of this study was to investigate hidration status, immue parameters, and isometric strenght in professional MMA fighters who underwent smaller (group 1, n = 6) or greater (group 2, n = 6 ) rapid weight loss in two momwnts: at weigh-in and immediately prior to the competition. We used blood tests to quantify the total and differential leukocyte count,, handgrip strength test and verified variation among the usual weight and weight at the time of the fight. Groups were divided establishing percentile 50%, considering delta perceptual of weight loss from the usual weight and weigh-in weight. Even after verify normality of the sample distributionby the Shapiro-Wilk test, we decided to use non-parametric statistical analysis, given the fact the sample size. We used Mann-Whitney test to verify thedifference between groups and Wilcoxon test to verify the difference between moments. . Values are expressed as median, mean ?? standard deviation. The median and the average percentage of weight loss delta are statistically different between the groups (p???0,05). Group 1: median = 5.54, mean = 6.45 ?? 3.98%, and Group 2: median = 12, 99, mean = 14.23 ?? 2.52%. The groups are homogeneous in the following variables: age (Group 1: median = 22, mean = 26.5 ?? 11.30 years; Group 2: median = 27, mean = 27.5 ?? 2.35 years); height (Group 1: median 174.5, mean = 176.8 ?? 0.06 cm; Group 2: median = 176, mean = 177.2 ?? 0.04 cm); BMI (Group 1: median = 25.17, mean = 25.23 ?? 2.71 kg / m 2, Group 2: median = 25, 06, mean = 25.54 ?? 1.26 kg / m2) body weight (Group 1: median 78.5, mean = 78.67 ?? 6.15 kg; Group 2: median 79.0, mean = 80.17 ?? 4,83kg). Between groups, we observed total leukocytes decreased in Group 1 (median = 8850, 11450 = maximum value, minimum value = 4850, mean = 8408.44 ?? 2585.6 mm3) compared to Group 2 ( median = 8300, maximum = 17400, minimum value = 4200, mean = 9208.3 ?? 4732.1 mm3) at the of weigh-in, with statistically significant difference (p <0.05).No significant differences between groups and moments were found for neutrophils, lymphocytes and neutrophil/lymphocyte ratio. Furthermore, no significant differences were observed on absolute and relative isometric handgrip strength between groups and moments. In conclusion, greater rapid wight loss can transiently downregulate immune parameters. We elucidate the needin of rules to determinate maximum values of weight loss and regain prior to championships. / As competi????es de MMA s??o delimitadas por categorias de peso. Grande parte dos atletas costuma manter seu peso corporal usual acima do limite da categoria que lutam, perdendo grande quantidade de peso para a pesagem, com subsequente recupera????o do peso perdido at?? o momento da luta. Portanto, o objetivo do presente estudo foi verificar, no momento da pesagem e imediatamente anterior ?? competi????o, a hidrata????o, par??metros imunes, e desempenho em lutadores profissionais de MMA que realizaram perda de peso r??pida pr??-competitiva, em menor (Grupo 1, n = 6) ou maior (Grupo 2, n = 6) escala, por meio de an??lises sangu??neas para quantifica????o total e diferencial de leuc??citos, for??a de preens??o palmar e varia????o entre o peso usual e peso no momento da luta. A divis??o dos grupos foi feita estabelecendo percentil 50%, considerando o delta percentual de perda de peso entre o peso usual e peso de pesagem. Mesmo ap??s verifica????o da normalidade da distribui????o da amostra por meio do teste Shapiro Wilk optou-se por utilizar an??lise estat??stica n??o param??trica U de Mann-Whitney para verificar a diferen??a de m??dias entre os grupos e teste de Wilcoxon para verificar a diferen??a entre momentos, haja visto o tamanho da amostra. Os valores est??o expressos em mediana, m??dia ?? desvio padr??o. As medianas e as m??dias do delta percentual de perda de peso foram estatisticamente diferentes (p???0,05) entre os grupos, sendo que no Grupo 1: mediana = 5,54, m??dia = 6,45 ?? 3,98% e no Grupo 2: mediana = 12,99, m??dia = 14,23 ?? 2,52%. Os grupos apresentam valores homog??neos nas seguintes vari??veis: idade (Grupo 1: mediana = 22, m??dia = 26,5 ?? 11,30 anos; Grupo 2: mediana = 27, m??dia = 27,5 ?? 2,35 anos); estatura (Grupo 1: mediana = 174,5, m??dia = 176,8 ?? 0,06 cm; Grupo 2: mediana = 176, m??dia = 177,2 ?? 0,04 cm); IMC (Grupo 1: mediana = 25,17, m??dia = 25,23 ?? 2,71 kg/m2; Grupo 2: mediana = 25, 06, m??dia = 25,54 ?? 1,26 kg/m2), peso corporal usual (Grupo 1:mediana = 78,5, m??dia = 78,67 ?? 6,15 kg; Grupo 2:mediana = 79,0, m??dia = 80,17 ?? 4,83kg). Em compara????o entre os dois grupos, observou-se valores de leuc??citos totais diminu??dos no Grupo 1 (mediana = 8850, valor m??ximo = 11450, valor m??nimo = 4850, m??dia = 8408,44 ?? 2585,6 mm3) em rela????o ao Grupo 2 (mediana = 8300, valor m??ximo = 17400, valor m??nimo = 4200, m??dia = 9208,3 ?? 4732,1 mm3), no momento da pesagem, com diferen??a estatisticamente significativa (p<0,05) para os testes n??o param??tricos. Nos neutr??filos, linf??citos e raz??o neutr??filo/linf??cito n??o foram observadas diferen??as significativas entre os grupos e momentos. N??o foram observadas diferen??as significativas na for??a de preens??o palmar absoluta e relativa no dia da pesagem e luta entre os grupos nos momentos. Conclui-se que a perda de peso r??pida pode influenciar par??metros imunes de forma transit??ria. Salienta-se a import??ncia de regras que determinem valores m??ximos de perda e recupera????o de peso nos campeonatos.

At the same time, losses occur in the autonomic nervous system. It is unknown how the autonomic function is related to these losses and whether a walking program can modify the heart rate variability (HRV) in this population. The aim of this study was to assess HRV in patients with PD and its relationship with anxiety and depression symptons, functional performance and severity of disease, and also the effect of a walking program in autonomic modulation and functional capacity. In cross- sectional phase were evaluated 26 patients (16 men / 10 women, 57.4 ?? 9.2 years) using the scales of anxiety, depression (HADS-A and HADS-D) and disease severity (UPDRS motorexamination and Hoehn and Yahrd scales). Functional performance was evaluated by the Timed Up and Go test (TUG) and three tests from the Senior Fitness Tests. These results were correlated with HRV indexes of time (RMSSD, SDNN) and frequency domain (HF, LF, LF / HF, TP, HF / TP, LF / TP) and nonlinear analysis (SampEn and DFA1) measured in sitting and standing position. The HRV variation from sitting to standing position (??? analysis) was also considered. In longitudinal phase a walking group (WG, n = 13) and a control group (CG n = 6) were formed through a randomized controlled trial. The home-based walking program had a duration of six weeks. The patients in the WG group were reassessed after 12 weeks of training. Were observed high levels of anxiety (30.7%) and depression (34.6%) in the patients evaluated. Depressive symptoms were associated to the parasympathetic activity: RMSSD (r = - 0.382; p ??? 0.05), as the activity in the both sympathetic and parasympathetic branches: LFseated (r = -0383; p ??? 0.05), LFstanding (r = -0.411; p ??? 0.05), TPstanding (r = -0, 504, p ??? 0.05) and ??? SampEn (r = -0384, p ??? 0.05). The severity and duration of illness also were negatively associated with autonomic function. RMSSDseated (r = -0.438; p ??? 0.05), SDNNseated (r = -0.452; p ??? 0.05) SDNNstanding (r = -0.602, p ??? 0.01); LFstanding (r = -0.603; p ??? 0.01); TPstanding (r = -0.504; p ??? 0.05) and LF/ TPstanding (r = -0.504; p ??? 0.05) were negatively associated with time to perform the TUG test. Other significant correlations (p ??? 0.05) of physical and functional tests and age HRV were observed . The six-weeks walking program have promoted significant changes in SampEn index (which measures the irregularity of HR data) in WG group compared to the CG group (20.47 vs -22.81%; CA and CO, respectively; p = 0.033) as well as ???SampEn measure (-22.83% vs. 18.46; WG and CG, respectively; p = 0.022), suggesting positive changes in autonomic function. At week 12, the WG group patients exhibited increased ratios of HF/TPstanding (7.0%; p = 0.017) and SampEn-standing (20.5%; p = 0.008; respectively), and reduction of the LF/HFstanding index (-10.65%; p = 0.012 ) compared to the first week, suggesting improvements in autonomic balance. There was an increase in sit-to-stand repetitions (10.50 ?? 1.93 to 13.25 ?? 1.58 repetitions; p = 0.021) and reduced time to perform the TUG test (7.34"?? 0.67 to 6.91" ?? 0.83, p = 0.002). Several HRV indices measured before walking program (SDNN, RMSSD, LF, HF, LF / TP) have shown correlations with the functional gain (r2 ranging from 0.62 to 0.81), suggesting a role of autonomic function in neuromuscular adaptation to training. It follows that HRV may work as an integrative measure and also as a peripheral marker of body's adaptability and its self-regulatory capacity, besides a practical and sensitive tool e to the disease progression. The home-based walking program have improved autonomic function of participants, often hampered by the disease. This is particularly interesting in that many bodily functions impaired in PD are mediated by autonomic function. / A redu????o da produ????o de dopamina na Doen??a de Parkinson (DP) afeta substancialmente a motricidade e outras fun????es org??nicas primordiais, como humor e a cogni????o, bem como o desempenho funcional. Paralelamente, ocorrem preju??zos no sistema nervoso aut??nomo. N??o se sabe como a fun????o auton??mica se relaciona com estes preju??zos e se um programa de caminhada pode modificar a variabilidade da frequ??ncia card??aca (VFC) desta popula????o. O objetivo deste estudo foi avaliar a VFC de pacientes com DP e a sua rela????o com os sintomas de ansiedade, depress??o, desempenho funcional e gravidade da doen??a, e tamb??m o efeito de um programa de caminhada na modula????o auton??mica e na capacidade funcional. Na etapa transversal foram avaliados 26 pacientes (16 homens/ 10 mulheres; 57,4 ?? 9,2 anos) pelas escalas de ansiedade, depress??o (HADS-A e HADS-D) e gravidade da doen??a (UPDRSexame motor e Hoehn e Yahrd). O desempenho funcional foi avaliado pelos testes Timed up and Go (TUG) e tr??s testes da bateria Senior Fitness Test. Estes resultados foram correlacionados com ??ndices da VFC no dom??nio do tempo (RMSSD, SDNN) e da frequ??ncia (HF, LF, LF/HF, TP, HF/TP, LF/TP), e an??lise n??o linear (SampEn e DFA1) aferidos na posi????o sentado e em p??. A varia????o da VFC da posi????o sentada para em p?? (valores em ??) tamb??m foi considerada. Na etapa longitudinal foram formados um grupo de caminhada (CA; n=13) e um grupo controle (CO; n=6), a partir de um ensaio cl??nico randomizado. O programa de caminhada home-based teve dura????o de seis semanas. Os pacientes do grupo CA foram reavaliados ap??s 12 semanas de treinamento. Foram observados elevados n??veis de ansiedade (30,7%) e depress??o (34,6%) nos pacientes avaliados. Os sintomas depressivos associaram-se tanto ?? atividade parassimp??tica: RMSSD (r= - 0,382; p ??? 0,05), quanto ?? atividade conjunta nos ramos simp??tico e parassimp??tico: LFsent (r= -0.383; p ??? 0,05), LFem p?? (r= -0,411; p ??? 0,05), TPemp?? (r= -0, 504; p ??? 0,05) e ?? SampEn (r= -0.384; p ??? 0,05). A gravidade e tempo da doen??a tamb??m se associaram negativamente ?? fun????o auton??mica. RMSSDsentado (r= -0,438; p ??? 0,05), SDNNsentado (r= -0,452; p ??? 0,05) e SDNNemp?? (r= -0,602; p ??? 0,01); LFemp?? (r= -0,603; p ??? 0,01); TPemp?? (r= -0,504; p ??? 0,05) e LF/TPemp?? (r= -0,504; p ??? 0,05) foram negativamente associados ao tempo no teste TUG. Outras correla????es significativas dos testes f??sico-funcionais e da idade com a VFC foram observadas. O programa de seis semanas de caminhada promoveu varia????es significativas do ??ndice SampEn (que mede a irregularidade dos dados de FC) no grupo CA em rela????o ao grupo CO (20,47 vs ???22,81%; CA e CO, respectivamente; p=0,033), assim como o ??ndice ??SampEn (-22,83 vs 18,46%; CA e CO, respectivamente; p=0,022), sugerindo mudan??as positivas na fun????o auton??mica. Na 12?? semana, os pacientes do grupo CA exibiram aumento dos ??ndices HF/TPemp?? (7,0%; p=0,017) e SampEn-em p?? (20,5%, p= 0,008), respectivamente) e redu????o do ??ndice LF/HFemp?? (-10,65 %; p=0,012) em rela????o ?? 1?? semana, sugerindo melhoras no equil??brio auton??mico. Houve aumento no n??mero de agachamentos (de 10,50 ?? 1,93 para 13,25 ?? 1,58 repeti????es; p= 0,021) e redu????o no tempo para realizar o TUG ( de 7,34??? ?? 0,67 para 6,91 ?? 0,83, p=0,002). V??rios ??ndices de VFC aferidos na tes do programa de caminhada (SDNN, RMSSD, LF, HF, LF/TP) mostraram correla????es com o ganho funcional (r2 variando de 0,62 a 0,81), sugerindo papel da fun????o auton??mica na adapta????o neuromuscular ao treinamento. Conclui-se que a VFC pode funcionar como medida integrativa e marcador perif??rico da adaptabilidade do organismo e da sua capacidade autoregulat??ria, al??m de recurso de avalia????o pr??tico e sens??vel ?? progress??o da doen??a. O programa de caminhada home-based melhorou a fun????o auton??mica dos participantes, frequentemente prejudicada pela doen??a. Isto ?? particularmente interessante na medida em que v??rias fun????es org??nicas debilitadas na DP s??o mediadas pela fun????o auton??mica.
