Objective: Design a clinical study to assess the efficacy of body suspension with tilting exercises on functional and quality of life outcomes in PD. Design, Setting, and Participants: This is an assessor-blinded, randomized and controlled clinical trial. A total of 48 subjects with moderate PD were recruited from the Neurological Service of S?o Lucas Hospital, PUCRS, Brazil. Recruitment took place between September 2015 and May 2016. The entire protocol study lasted 16 weeks, with 8 weeks of exercise protocol and 8 weeks of follow-up. Interventions: Subjects were randomly assigned to either body suspension with tilting exercises (intervention group) or stretching exercises (control group). Main Outcomes and Measures: The primary outcome was the Timed Up and Go test at the 8th week. Secondary outcomes were Berg Balance Scale (BBS); Functional Reach Test (FRT); Unified Parkinson?s Disease Rating Scale (UPDRS) and Parkinson?s Disease Questionnaire (PDQ-39). These measures were assessed at baseline (before trial entry) and then at the 8th (end of exercise protocols) and 16th weeks (8 weeks of follow-up) after randomization. Results: Of the 48 subjects randomized in the study 20 received the intervention (71.3?6.3 years old) and 20 were controls (66.7?6.4 years old). Eight of them were lost during the trial (four per group). Analysis of co-variance, with adjustment for baseline measurement, revealed a between-group difference in the Timed Up and Go test at 8th week [CI95% difference of -4.90 (-5.80 a -4.00), p<0.0001] and in the follow-up [CI95% difference of -4.94 sec (-5.82 to -4.06), p<0.0001], which was our primary outcome. Significant between-groups differences were also found for all secondary outcomes (BBS, UPDRS-III, FRT, and PDQ-39) at 8th week and follow-up (16th week) assessments. Conclusions and relevance: We suggest the body suspension with tilting exercises protocol (the Chordata Method) improves functionality and quality of life in subjects with moderate PD. This evidence supports the Chordata method appears to be a new effective therapeutic option to treat Parkinson-related mobility and balance dysfunctions. / Import?ncia: A efic?cia da utiliza??o de exerc?cios de suspens?o e pendula??o corporal (m?todo Chordata) para o tratamento de sujeitos com a Doen?a de Parkinson ainda n?o foi testada. Objetivo: Realizar um estudo cl?nico para avaliar a efic?cia de um programa de exerc?cios de suspens?o e pendula??o corporal sobre a funcionalidade e qualidade de vida de sujeitos portadores da doen?a de Parkinson. Delineamento, M?todo e Participantes: Trata-se de um ensaio cl?nico, controlado e randomizado, com avaliador de desfecho alheio aos grupos experimentais. Um total de 48 sujeitos com diagn?stico m?dico de doen?a de Parkinson, de est?gio leve ? moderado, foram recrutados a partir do Servi?o de Neurologia do Hospital S?o Lucas da PUCRS, Brasil. O recrutamento ocorreu entre Setembro de 2015 e Maio de 2016. O protocol do estudo teve a dura??o de 16 semanas, sendo 8 semanas de pr?tica dos exerc?cios propostos, com iguais 8 semanas de seguimento (follow-up). Interven??o: Os sujeitos foram randomizados nos grupos interven??o (suspens?o e pendula??o corporal) e controle (alongamentos de grandes grupos musculares). Desfechos principais e medidas: O desfecho prim?rio do presente estudo foi o teste do Timed Up and Go ao final do protocolo de treinamento (8 semanas). Os desfechos secund?rios foram a Escala de Equil?brio de Berg (EEB); o teste do Alcance Funcional (TAF); a Escala Unificada da Doen?a de Parkinson, sess?o III (UPDRS-III) e o Question?rio de Qualidade de Vida na Doen?a de Parkinson (PDQ-39). Estes desfechos foram avalaidos nos momentos pr?-interven??o, ap?s, ao t?rmino do protocol de exerc?cios (8 semanas) e no per?odo de seguimento (16 semanas ap?s a randomiza??o). Resultados: De um total de 48 sujeitos randomizados, 20 participaram do grupo interven??o (71,3?6,3 anos de idade) e 20 do grupo controle (66,7?6,4 anos de idade). Oito sujeitos foram perdidos durante a execu??o do estudo (quarto em cada um dos grupos). A An?lise de co-vari?ncia, com ajuste para os dados basais, revelou uma diferen?a entre-grupos no teste do Timed Up and Go ao t?rmino do protocolo de exerc?cios (8 semanas) [diferen?a IC95%: -4,90 (-5,80 a -4,00), p<0,0001] e na avalia??o de seguimento [diferen?a IC95%: -4.94 sec (-5,82 to -4,06), p<0.0001], teste este estabelecido como o desfecho prim?rio. Diferen?as significativas tamb?m foram encontradas para todos os desfechos secund?rios (EEB, UPDRS-III, TAF e PDQ-39) em ambas as avalia??es p?s-interven??o (8 e 16 semanas ap?s a randimiza??o). Conclus?es e relev?ncia: Nossos resultados sugerem que os exerc?cios de suspens?o e pendula??o corporal s?o capazes de melhorar a funcionalidade e a qualidade de vida de sujeitos com a doen?a de Parkinson, em est?gio moderado. Esta evid?ncia suporta que o m?todo Chordata parece ser uma nova e efetiva interven??o terap?utica para o tratamento das desordens de mobilidade e equil?brio associadas ? doen?a de Parkinson.

Despite the diversity of goals and propositions, these studies show that psychologists have been significantly inserted into the social policies field, implying changes in the profession. Since the 1980s, researches in Rio Grande do Norte corroborate the results of national studies. The aim of this paper is to study the insertion and professional career of psychologists in the social policies field in Rio Grande do Norte. In order to accomplish the final results of this paper, it was developed an exploratory research, with the use of a questionnaire, comprised of four parts: general data, academic graduation, complementary graduation and professional experience. The results show three groups of information: characterization, insertion and professional performance. It has been verified expressive insertion of psychologists into the social policies field (41%). The socio-demographic and graduation characteristics are not different from those shown by literature: women, young, from families with an average of 7 to 15 minimum wages. Most of them graduated from public institutions and with post-graduation studies in clinical area. The professionals studied seem to be in worse working conditions compared to the rest of the category, which are also in unfavorable conditions, especially the psychologists who work in social assistance institutions, which present greater problems in its structure. The activities developed do not show anything new, reserving conservative practices instead of effective innovations, emphasizing the discussion on the profession for not considering demands presented to the psychologists in the social policies field. With unique scenario, the eproduction of liberal values corroborates classic performance standards; an unpolitical and uncritical practice is diffused. It is then reconsidered the importance of critical studies that organize goals to the category, with the aim of political transformation concerning the current scenario. / Desde os primeiros anos da regulamenta??o da profiss?o de psic?logo no Brasil, t?m-se realizado estudos que versam sobre forma??o, pr?tica, locais de atua??o e compromisso social da categoria. Apesar da diversidade de objetivos e propostas, esses estudos constatam que psic?logos t?m se inserido significativamente no campo das pol?ticas sociais, implicando mudan?as na profiss?o. Desde a d?cada de 1980, pesquisas no Rio Grande do Norte corroboram resultados de estudos nacionais. O objetivo deste trabalho ? estudar a inser??o e a atua??o profissional do psic?logo no campo das pol?ticas sociais no Rio Grande do Norte. Para consecu??o deste, desenvolveu-se pesquisa explorat?ria, com uso de question?rio, composto por quatro partes: dados gerais, forma??o acad?mica, forma??o complementar e exerc?cio profissional. Os resultados apontam tr?s grupos de informa??es: caracteriza??o, inser??o e atua??o profissionais. Constatou-se inser??o significativa do psic?logo no campo das pol?ticas sociais (41%). Suas caracter?sticas s?cio-demogr?ficas e de forma??o n?o diferem das apresentadas pela literatura: mulheres, jovens, advindas de fam?lia entre 7 e 15 Sal?rios-M?nimos. Maior parte ? graduada em institui??o p?blica e faz especializa??o na ?rea cl?nica. Os profissionais estudados aparentam estar em piores condi??es de trabalho, se comparado ao resto da categoria, que j? apresenta condi??es desfavor?veis, com destaque para os psic?logos que atuam em institui??es de Assist?ncia Social, com maior precariza??o. As atividades desenvolvidas n?o apresentam novidade, com consolida??o de pr?ticas conservadoras, ao inv?s de inova??es efetivas, enfatizando o questionamento ? profiss?o, por n?o contemplar demandas apresentadas ao profissional de Psicologia no campo das pol?ticas sociais. Com este cen?rio ?nico, de reprodu??o de valores liberais, corroboram-se padr?es cl?ssicos de atua??o, propaga-se e difunde-se uma pr?tica apol?tica e acr?tica. Reitera-se a import?ncia de estudos cr?ticos, que organize metas para a categoria, com intuito de transforma??es pol?ticas que contemplem o cen?rio atual

In spite of this, only a few studies elucidate the effect sleep deprivation has on the thyroid function, as well as studies on any role exercise might have in the prevention of such alterations. The objective of this study is to assess the protective effect of the strength exercise on the thyroid function in rats that went through paradoxical sleep deprivation for 24 and 96 hours, as well as a rebound sleep for 24 hours. For this study male and female Wistar rats were used (200-250g), submitted to sleep deprivation using the modified multiple platforms, and the isometric exercise was offered by the inverted box proposed by Lac & Cavalie (1999). The animals were distributed in 6 groups: Control (C, males n=8, females = 13); Trained (T, males n=8; females n=13), Trained, with Sleep Deprivation of the paradoxical sleep for 24 and 96 hours (respectively TPSP24 e TPSP96 males n=10; females n=13); Trained with Sleep Deprivation for 24 and 96 hours, plus a rebound sleep for 24 hours (TPSP24R e TPSP96R males n=10; females n=13). All animals went through and adaptation to the strength exercise for 5 days, enduring 5 series of 30 seconds of strength with rest periods of 25 seconds between each series. After adaptation, an extra weight was added to the animal's tail. All animals were killed on the same day and their blood was collected for analysis of T3 (ng/dL), T4 (ug/dL), e TSH (ng/mL) using the radioimmunoassay technique. Ethics committee approval was granted by number UFRRJ N?003/2015. After the statistical analysis we observed a significant body weight loss, both in females and males, and a relative loss in hypophysis weight in males from group T. On the other hand, the relative weight of the adrenal was reduced in the T group of males, and increased in both the T and TP24 groups of females. In males, seric TSH levels have risen with the exercise, normalizing after the deprivation of 24 and 96 hours, and the rebound in the PS96 group. The PSP was able to induce a raise in the T3 level in the groups TP24 and TP96 in males ? no significant alterations were observed in females. As for the seric T4 in males, there was no alteration, although in females the 24 hours PSP was able to rise those values. This study indicates a protective effect by the isometric exercise, preventing TSH and seric T4 and T3 alterations induced by deprivation of the paradoxical sleep. As such more studies are necessary to clarify the mechanisms involved in such protection / A vida moderna tem diminu?do o tempo de sono da maioria da popula??o e as consequ?ncias dessa redu??o t?m sido estudadas em humanos e modelos animais. J? o papel da tire?ide na priva??o de sono associada com exerc?cios de for?a n?o est? bem estabelecido, pois n?o tem sido estudado. Este estudo, no entanto, tem como objetivo avaliar o efeito protetor do exerc?cio de for?a sobre a fun??o tireoidiana em ratos ap?s a priva??o de sono paradoxal (PSP) por 24 e 96 horas assim como o sono rebote de 24 horas. Para a realiza??o deste trabalho, foram utilizados ratos machos e f?meas Wistar (200-250g) submetidos a priva??o de sono pela metodologia das plataformas m?ltiplas modificadas e o exerc?cio isom?trico foi feito pela metodologia da caixa invertida proposta por Lac & Cavalie (1999). Os animais machos foram distribu?dos em 6 grupos: Controle (C n=8 machos; f?meas, n=13); Treinado (T=8 machos; f?meas, n=13); Treinado com Priva??o de sono paradoxal por 24 horas e 96 horas (TPSP24 e TPSP96 n=10, machos; f?meas, n=13); Treinado com Priva??o de sono paradoxal por 24 horas e 96 horas mais per?odo de sono rebote por 24 horas (TPSP24R e TPSP96R n=10, machos; f?meas, n=13). Os animais foram adaptados ao exerc?cio de for?a por 5 dias, onde era constitu?do por 5 s?ries de 30 segundos de for?a com intervalos de descanso por 25 segundos entre as s?ries. Ap?s a adapta??o, foi adicionado um peso extra na cauda desses animais. Todos os animais foram eutanasiados no mesmo dia, o sangue coletado para an?lise de T3 ng/dL, T4 ?g/dL, e TSH ng/mL pela t?cnica de Radioimunoensaio. Aprova??o pelo comit? de ?tica da UFRRJ N?003/2015. Ap?s an?lise, observamos perda do peso corporal tanto nas f?meas quanto nos machos e uma diminui??o no peso relativo da hip?fise apenas nos machos do grupo T. Por outro lado, o peso relativo da adrenal se manteve reduzido no grupo T dos machos e aumentado no grupo T e TP24 das f?meas. Os n?veis s?ricos de TSH nos machos aumentaram com o exerc?cio nos grupos T, normalizando com a priva??o de 24 horas e retornando ao aumento no grupo TP24R. A PSP foi capaz de provocar um aumento nos n?veis de T3 nos grupos TP24 e TP96 dos machos, e nas f?meas n?o foi observado altera??es significativas. Quanto aos valores de T4 nos machos, n?o foi constatado altera??es significativas e nas f?meas a PSP foi capaz de elevar tais valores. Sugerimos que o exerc?cio de for?a esteja contribuindo para a prote??o dos impactos agressivos causados pela priva??o de sono paradoxal na fisiologia end?crina tanto em machos quanto em f?meas.

Aiming to answer how the advisory and consulting processes are being operationalized in the training and professional practice of social workers in Rio Grande do Sul, the objective was to analyze the aspects related to the training and professional practice of social workers in the advisory and discussing challenges and possibilities. This is a qualitative study, guided by the dialectical-critical method, based on documental, bibliographical and empirical research, totalizing a sample of twenty-three (23) documents for documentary research, thirty-two (32) research productions and twenty-five (25) subjects participating in the empirical research (coordinators, teachers and students of the Bachelor's degree in Social Work). For the treatment and analysis of the data, the content analysis based on Pag?s (2006) was used. It is concluded that there are contradictions in the recognition of the importance of teaching the advisory and consulting processes now being denied, sometimes being placed in the background, during training, as well as in the way in which it is being addressed by UFAS. This reality reflects and may explain the incipient manifestation of professional practice in these processes. From the data, it is pointed out the importance of the work of social workers in these processes, and the subjects surveyed stressed the need for Social Work to reorganize itself to expand its work in these spaces, to strengthen the formation process and the materialization of the ethical- political, since these processes are in line with it. Finally, propositions are presented to contribute to overcoming the limits and materialization of the possibilities of acting in these processes. / O presente estudo aborda os processos de assessoria e consultoria, debatendo o ensino e o exerc?cio profissional dos assistentes sociais, considerando que estes processos s?o atribui??es privativas e compet?ncias profissionais, no entanto, s?o espa?os pouco ocupados pela categoria profissional, em que a produ??o do conhecimento se manifesta de forma incipiente. Visando responder como os processos de assessoria e consultoria est?o sendo operacionalizados na forma??o e no exerc?cio profissional dos assistentes sociais do Rio Grande do Sul, elencou-se como objetivo analisar os aspectos relacionados ? forma??o e ao exerc?cio profissional dos assistentes sociais nos processos de assessoria e consultoria, debatendo sobre desafios e possibilidades. Trata-se de um estudo qualitativo, orientado pelo m?todo dial?tico-cr?tico, que se amparou em pesquisa documental, bibliogr?fica e emp?rica, totalizando uma amostra de vinte e tr?s (23) documentos para pesquisa documental, trinta e duas (32) produ??es para pesquisa bibliogr?fica e vinte e cinco (25) sujeitos participantes da pesquisa emp?rica (coordenadores, docentes e alunos dos cursos de Bacharelado em Servi?o Social). Para o tratamento e an?lise dos dados, foi utilizada a an?lise de conte?do baseada em Pag?s (2006). Conclui-se que, h? contradi??es no reconhecimento da import?ncia do ensino dos processos de assessoria e consultoria ora sendo negado, ora sendo colocado num segundo plano, durante a forma??o, bem como na forma como o mesmo est? sendo abordado pelas UFAS. Esta realidade reflete e pode explicar a manifesta??o incipiente do exerc?cio profissional nestes processos. A partir dos dados, aponta-se para a import?ncia do trabalho dos assistentes sociais nestes processos, tendo os sujeitos pesquisados salientado a necessidade do Servi?o Social se reorganizar para ampliar sua atua??o nestes espa?os, fortalecer o processo de forma??o e a materializa??o do projeto ?tico-pol?tico, posto que esses processos est?o alinhados com o mesmo. Por fim, s?o apresentadas proposi??es para contribuir na supera??o dos limites e materializa??o das possibilidades de atua??o nesses processos.

The sample consisted of 60 individuals , divided randomly into control group , experimental group to the experimental group and moderate exercise to intense exercise aged 7 to 14 years . Initial tests to characterize the sample and spirometry for verification and determination of VO2max values for exercise intensity were applied . And the second time were applied cognitive tests ( Flanker and oddball paradigm ) moderate or intense physical exercise , with the reapplication of cognitive tests after acute exercise . It was observed that held moderate and intense aerobic exercise differ statistically from the control group in the executive function testing and procurement of P300. In testing the intense attention the only group differed significantly from the control group mind. In both tests the intensive group achieved better results compared to the other groups. The neuroelectrical frontoparietal network was established for the Flanker paradigm and frontoparietal network and the temporal to the oddball paradigm. We conclude that the results point to a favorable direction of physical activity in the school of moderate and intense in general. / Essa pesquisa teve como objetivo analisar o perfil das respostas da fun????o executiva e as ativa????es neuroel??tricas a partir do componente P300 de escolares sob est??mulos agudos de exerc??cio f??sico em diferentes intensidades.

Evid?ncias recentes sugerem que o exerc?cio de alta intensidade pode induzir altera??es fisiol?gicas que diminuem o apetite, contribuindo para redu??o da ingest?o cal?rica, fen?meno conhecido como anorexia induzida pelo exerc?cio (AIE). Objetivo: comparar o efeito agudo do exerc?cio intervalado de alta intensidade (EIAI) e exerc?cio cont?nuo de intensidade moderada (ECMI) sobre o consumo energ?tico e percep??o do apetite em homens com obesidade. M?todos: A pesquisa caracterizou-se como um ensaio cl?nico randomizado com delineamento cruzado. Quinze volunt?rios (31,0 ? 6,1 anos, 31,0 ? 6,0 kg/m?, 40,1 ? 2,2% de gordura corporal) foram submetidos a tr?s sess?es experimentais, separadas por sete dias: I) EIAI (10 x 1 min a 90% da frequ?ncia card?aca m?xima [FCm?x] + 1 min recupera??o ativa), II) ECMI (20 min a 70% da FCm?x) e III) Controle (sem exerc?cio). Uma refei??o padronizada foi oferecida 60 min antes de cada sess?o. A percep??o subjetiva do apetite (fome, saciedade, plenitude e perspectiva de consumo alimentar) foi avaliada por meio de uma escala visual anal?gica (EVA) em tr?s momentos: 1) pr?-sess?o, 2) p?s-sess?o e 3) uma hora ap?s sess?o. O consumo alimentar ad libitum foi analisado uma hora ap?s as sess?es experimentais e controle, por meio de registro pesado e o consumo alimentar ao longo do dia da sess?o (24 h) foi avaliado por meio de um registro alimentar estimado. A ANOVA two-way com medidas repetidas foi utilizada para analisar poss?veis diferen?as entre as condi??es e momentos na percep??o do apetite e uma ANOVA de medidas repetidas para analisar as diferen?as entre as condi??es no consumo alimentar ad libitum e 24 h. Resultados: N?o houve diferen?as significativas na percep??o de fome [F(1,3, 17,5)=0,00, p=0,972], saciedade [F(1,3, 17,5)=0,00, p=0,972], plenitude [F(2, 28)=0,13, p=0,876] e perspectiva de consumo [F(2, 28)=0,76, p=0,476] entre as condi??es, bem como n?o foram identificadas diferen?as significativas no consumo energ?tico na refei??o ad libitum: CON (674,5 ? 252,1), ECMI (666,7? 213,8) e EIAI (689,6? 263,8kcal) [F (2, 28)=0,13, p=0,877] e ao longo do dia da sess?o: CON (2857,6 ? 867,2), ECMI (2608,5? 595) e EIAI (2556,1? 489,5kcal) [F (2, 28) = 1,54, p=0,233]. Conclus?o: Uma sess?o de EIAI e ECMI n?o modificou o apetite e o consumo energ?tico ap?s 60 min e ao longo do dia em homens com obesidade. / Introduction: Physical exercise is considered a fundamental strategy in the treatment of obesity by promoting increase in the caloric deficit. Recent evidence suggests that high-intensity exercise can induce physiological changes that suppress appetite, decreasing caloric intake, a phenomenon known as exercise-induced anorexia (EIA). Objective: compare the acute effect of high intensity interval exercise (HIIE) and continuous moderate intensity exercise (ECM) on energy intake and appetite perception in obese men. Methods: The study was characterized as a randomized clinical trial in cross-over design. Fifteen volunteers (31.0 ? 6.1 years, 31.0 ? 6.0 kg/ m?, 40.1 ? 2.2% body fat) underwent three experimental sessions, seven days apart: I) HIIE ( 10x 1 min at 90% of maximal heart rate [HRmax] + 1 min active recovery), II) ECM (20min to 70% of HRmax) and III) Control (without exercise). A standardized meal was offered 60 min before each session. Appetite perception (hunger, satiety, fullness and perspective food consumption) were evaluated through a visual analogue scale (VAS) in three moments: 1) Pre-session, 2) Post-session and 3) one hour after session. Energy intake was assessed one hour after session with an ad libitum meal and the consumption throughout the day (24hrs) was analyzed with a estimated food record. ANOVA Two-way with repeated measures was used to analyze the differences between conditions and moments on appetite perception and ANOVA with repeated measures to assess the differences between conditions on energy intake in ad libitum and 24hrs. Results: There were no significant differences on hunger [F (1.3, 17.5) = 0.00, p = 0.972], satiety [F (1.3, 17.5) = 0.00, p = 0.972], fullness [F (2, 28) = 0.13, p = 0.876] and prospective food consumption [F (2, 28) = 0.76, p = 0.476] between conditions. As well as no significant differences on energy intake were observed during ad libitum meal: CON (674,5 ? 252,1), ECM (666,7? 213,8) e HIIE (689,6? 263,8kcal) [F (2, 28) = 0.13, p = 0.877] and throughout the day CON (2857,6 ? 867,2), ECM (2608,5? 595) e HIIE (2556,1? 489,5kcal) [F (2, 28) = 1.54, p = 0.233].Conclusion: A single session of HIIE and ECM did not modified appetite and energy intake 60 min after and during the day following exercise in obese man.

Dessa forma, hipertensos poderiam apresentar respostas de dissipa??o de calor aprimoradas, especialmente durante a recupera??o do exerc?cio f?sico moderado realizado sob condi??o de estresse t?rmico. Diante disso, o objetivo do estudo foi avaliar as respostas termorregulat?rias de sujeitos hipertensos durante e na recupera??o de exerc?cio f?sico de intensidade moderada realizado em ambiente quente. Para tanto, oito hipertensos essenciais (H) e oito normotensos (N) (idade: 46,5?1,3 e 45,6?1,4 anos; ?ndice de massa corporal: 25,8?0,8 e 25,6?0,6 kg/m2; press?o arterial m?dia: 98,0?2,8 e 86,0?2,3 mmHg, respectivamente) permaneceram na c?mara ambiental (38?C e 60% umidade relativa do ar) durante 2h e 30 minutos (30 minutos em repouso, 1h de exerc?cio na esteira (50% VO2pico) e 1h em recupera??o do exerc?cio). Temperaturas da pele e corporal interna, frequ?ncia card?aca e press?o arterial foram mensuradas. C?lculos de produ??o de calor, taxa de ac?mulo de calor, temperatura corporal, troca de calor por radia??o, convec??o, e atrav?s do trato respirat?rio e suor evaporado foram realizados a partir das vari?veis coletadas. Como resultados, a press?o arterial m?dia dos hipertensos foi maior do que dos normotensos durante todo o protocolo experimental (p < 0,05). Apesar dos par?metros termorregulat?rios avaliados n?o terem sido diferentes entre grupos hipertensos e normotensos em repouso e durante o exerc?cio f?sico no calor, os hipertensos apresentaram menor quantidade de calor acumulado (H: -24,23 ? 3,39 W/m?, N: -13,63 ? 2,24 W/m?, p = 0,03), maior varia??o na temperatura corporal (H: -0,62 ? 0,05 ?C, N: -0,35? 0,12 ?C, p = 0,03) e maior quantidade de suor evaporado (H: -106,1 ? 4,59 W/m?, N: -91,15 ? 3,24 W/m?, p = 0,01) no per?odo de recupera??o p?s-exerc?cio. Al?m disso, a quantidade de suor evaporado relacionou-se com calor acumulado (r = 0,82, p < 0,001) e com a varia??o da temperatura corporal durante a recupera??o p?s-exerc?cio f?sico (r = 0,82, p < 0,001). Concluindo, indiv?duos hipertensos essenciais, em uso dos medicamentos iECA e diur?ticos, apresentam dissipa??o de calor acumulado aprimorada, por meio da evapora??o do suor e, consequentemente, maior resfriamento corporal durante a recupera??o de exerc?cio f?sico de intensidade moderado em ambiente quente. Methods: A total of 8 essential hypertensive (H) and 8 normotensive participants (N) (age: 46.5 ? 1.3 and 45.6 ? 1.4 years, BMI: 25.8 ? 0.8 and 25.6 ? 0.6 kg/m2, mean arterial pressure: 98.0 ? 2.8 and 86.0 ? 2.3 mmHg, respectively) remained in the environmental chamber (38 ?C and 60 % relative humidity) for 2 hours and 30 minutes (30 min at rest, 1 h of treadmill exercise at 50 % of VO2max and 1 h at rest during recovery exercise). Skin and core temperatures, heart rate and blood pressure were measured. Calculations of heat production, heat storage, mean body temperature, heat exchange by radiation, convection and evaporated sweat were performed from the collected variables. Results: The mean blood pressure of the hypertensive subjects was higher than of the normotensive participants throughout the experimental protocol (p < 0.05). Although the thermoregulatory parameters evaluated did not differ between groups at rest and during exercise, the hypertensive subjects had lower amounts of heat storage (H: -24.23 ? 3.39 W/m?, N: -13.63 ? 2,2.4 W/m?, p = 0.03), greater variations in body temperature (H: -0.62 ? 0.05 ?C, N: -0.35? 0.12 ?C, p = 0.03), and a greater amount of evaporated sweat (H: -106.1 ? 4.59 W/m?, N: -91.15 ? 3.24 W/m?, p = 0.01) during the recovery period. Furthermore, the amount of evaporated sweat correlated with heat storage (r = -0.82; p < 0.001) and with the variation in mean body temperature during the recovery period (r = -0.82; p < 0.001). Conclusion: Essential hypertensive participants present with improved sweat evaporation and greater heat dissipation and body cooling during recovery from moderate-intensity exercise performed in the heat. / Disserta??o (Mestrado) ?

Thus, it is believed that hypertensive individuals have an enhanced response of heat dissipation, especially during recovery from moderate-intensity exercise performed under heat stress conditions. Thus, the aim of this study was to examine the thermoregulatory responses of hypertensive subjects during and after (recovery period) moderate-intensity exercise performed in the heat. Methods: A total of 8 essential hypertensive (H) and 8 normotensive participants (N) (age: 46.5 ? 1.3 and 45.6 ? 1.4 years, BMI: 25.8 ? 0.8 and 25.6 ? 0.6 kg/m2, mean arterial pressure: 98.0 ? 2.8 and 86.0 ? 2.3 mmHg, respectively) remained in the environmental chamber (38 ?C and 60 % relative humidity) for 2 hours and 30 minutes (30 min at rest, 1 h of treadmill exercise at 50 % of VO2max and 1 h at rest during recovery exercise).

No entanto, n?o h? dados publicados sobre o envolvimento do sistema colin?rgico central nestas respostas em modelo experimental que apresenta altera??o da sensibilidade dos barorreceptores e d?ficit termorregulat?rio. Assim, o objetivo do presente estudo foi verificar o envolvimento do sistema colin?rgico central na modula??o das repostas cardiovasculares e termorregulat?rias durante o repouso e exerc?cio f?sico em ratos espontaneamente hipertensos (SHR). Ratos Wistar machos (n = 33) e SHR (n = 33) foram implantados com uma c?nula intracerebroventricular (icv) para inje??es de 2 ?L de fisostigmina (fis) ou solu??o salina (sal). Temperaturas da cauda (Tcauda) e corporal interna (Tint), press?o arterial sist?lica (PAS), frequ?ncia card?aca (FC) e taxa metab?lica foram registradas durante os 60 minutos em que os ratos permaneceram em repouso, bem como durante o exerc?cio f?sico at? a fadiga ap?s inje??es icv randomizadas. Na situa??o repouso, o tratamento com fis iniciou uma sucess?o de respostas cardiovasculares e termorregulat?rias que resultaram em aumento da PAS, redu??o da FC e aumento de Tcauda nos grupos Wistar e SHR. A magnitude da ativa??o desses mecanismos foi mais intensa no SHR, afetando a Tint e melhorando a dissipa??o de calor. Durante o exerc?cio f?sico, o tratamento com fis foi capaz de modular as repostas cardiovasculares promovendo aumento significativo da PAS, seguido de bradicardia reflexa em ratos SHR e Wistar. Estas respostas foram mais intensas nos ratos Wistar. N?o houve diferen?a significativa para a Tcauda e Tint no grupo SHR fis em rela??o ao grupo sal. Entretanto, fis impactou positivamente no desempenho f?sico. Em conjunto, esses resultados fornecem evid?ncias que, durante a situa??o de repouso, a estimula??o colin?rgica central modula as repostas termorregulat?rias por meio de mudan?as no sistema cardiovascular de ratos Wistar e SHR, sendo que essas respostas s?o mais acentuadas em ratos SHR impactando na dissipa??o de calor. Durante o exerc?cio f?sico, a administra??o central de fis promove altera??es no sistema cardiovascular de ratos normotensos e hipertensos. Apesar dessas altera??es n?o terem sido suficientes para ajustar as respostas termorregulat?rias em ratos SHR, impactaram positivamente no desempenho f?sico. / Tese (Doutorado) ? Programa Multic?ntrico de P?s-Gradua??o em Ci?ncias Fisiol?gicas, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2017. / There is evidence that central cholinergic stimulation increases heat dissipation in normotensive rats through changes on the cardiovascular system via modulation of baroreceptors function. However, there is no published data regarding the involvement of the central cholinergic system in cardiovascular and thermoregulatory responses in spontaneously hypertensive rats (SHR), which are animals that possess altered baroreceptor sensitivity and thermoregulatory deficit. Therefore, the aim of this study was to verify the involvement of the central cholinergic system in cardiovascular and thermoregulatory adjustments in SHR. Male Wistar (n = 33) and SHR (n = 33) rats were implanted with an intracerebroventricular (icv) cannula for injections of 2 ?L of physostigmine (phy) or saline (sal) solution. Tail (Ttail) and internal body temperatures (Tint), systolic arterial pressure (SAP), heart rate (HR) and metabolic rate were registered during 60 minutes while the animals remained at rest and during exercise until fatigue after randomly receiving the injections. Phy treatment started a succession of cardiovascular and thermoregulatory responses that resulted in increased SAP, reduced HR and increased Ttail in both Wistar and SHR groups. The magnitude of the activation of these mechanisms seems to be more intense in SHR, even affecting the Tint, and improve heat dissipation. During physical exercise, the phy treatment was able to modulate the cardiovascular responses promoting a significant increase of SAP, followed by reflex bradycardia in SHR and Wistar rats. These responses were more intense in Wistar rats. There was no significant difference for Ttail and Tint in the SHR group, however, phy positively impacted the physical performance. Taken together, these results provide evidence that at rest the central cholinergic stimulation modulates thermoregulatory responses through changes in the cardiovascular system of Wistar and SHR rats, and SHR rats presented greater cardiovascular and thermoregulatory responses than normotensive rats after central cholinergic stimulation. During physical exercise the central administration of phy promotes adjustments in the cardiovascular system of normotensive and hypertensive rats. Although these adjustments were not sufficient to pair the thermoregulatory responses in SHR rats, they had a positive impact on physical performance.
