In face of this reality, daily dance practice is responsible for a number of benefits in everyday life, such as improved balance, motor coordination and blood pressure (BP) reduction. However, little is known about the acute effects of a playful dance session in the elderly. The objectives of the present study were to analyze the behavior of PA and HR during and after an acute ludic dance session in hypertensive elderly women; To verify the contribution of the dance of playful character as hypotensive agent of the Blood Pressure; Check the regulation of CF, through an acute dance session of a playful character; To demonstrate the dance of playful character as a propulsive tool to obtain the health of hypertensive elderly women. Ten elderly women (65 ?? 3, years) of a Group of Coexistence of Sector O, Ceil??ndia - DF were recruited. They performed a dance session of a playful character with an average duration of 60 minutes, which is divided into 5 ', 10', 40 'and 4' back. PA was measured at rest, at the end and post-exercise: 0 ', 5' and 10 'by the oscillometric method (BPA 100, Microlife, Switzerland). Repeated measures ANOVA was used for statistical analysis (Prism 6.0, USA). As a result, systolic blood pressure (SBP) increased immediately after the session (p <0.01). However, there was a significant reduction of SBP (p <0.05) in the recovery period at 5 'and 10' post-exercise, there was no change in diastolic BP (Table 1). This study demonstrated the cardiovascular safety of this modality of physical activity, and the potential benefit of dance in post-exercise hypotension in hypertensive elderly women. It is possible that this hypotensive effect may last for more than 10 'after the session. In the future the studies could analyze the cardiovascular parameters induced by the dance by a greater post-exercise period. / A hipertens??o arterial (HA) aumenta com o passar dos anos, acometendo principalmente as pessoas com mais de 60 anos. Diante dessa realidade, a pr??tica di??ria da dan??a ?? respons??vel por uma s??rie de benef??cios na vida cotidiana, como melhora do equil??brio, coordena????o motora e redu????o da press??o arterial (PA). No entanto, pouco se sabe dos efeitos agudos de uma sess??o de dan??a de car??ter l??dica em idosas. Para tanto os objetivos do presente estudo foi Analisar o comportamento da PA e FC durante e ap??s uma sess??o aguda de dan??a de car??ter l??dico em idosas hipertensas; Verificar a contribui????o da dan??a de car??ter l??dico como agente hipotensor da Press??o Arterial; Verificar a regula????o da FC, por meio de uma sess??o aguda da dan??a de car??ter l??dico; Demonstrar a dan??a de car??ter l??dico como uma ferramenta propulsora para obten????o de sa??de de idosas hipertensas. Foram recrutadas 10 mulheres idosas (65??3, anos) de um Grupo de Conviv??ncia do Setor O, Ceil??ndia ??? DF. Elas realizaram uma sess??o de dan??a de car??ter l??dica com dura????o m??dia de 60 minutos, sendo esta dividida em alongamento (5???), aquecimento (10???), parte principal (40???) e volta ?? calma (5???). A PA foi mensurada em repouso, final e p??s-exerc??cio: 0???, 5??? e 10???, pelo m??todo oscilom??trico (BPA 100, Microlife, Su????a). Foi usado ANOVA de medidas repetidas para an??lise estat??stica (Prism 6.0, USA). Como resultados a press??o arterial sist??lica (PAS) aumentou imediatamente ap??s a sess??o (p <0,01). No entanto, houve uma redu????o significativa da PAS (p <0,05) no per??odo de recupera????o aos 5??e 10??p??s- exerc??cio, n??o houve altera????o na PA diast??lica (Tabela 1). Este estudo demonstrou a seguran??a cardiovascular desta modalidade de atividade f??sica, e o potencial benef??cio da dan??a na hipotens??o p??s-exerc??cio em idosas hipertensas. ?? poss??vel que este efeito hipotensor possa perdurar por mais de 10??? ap??s a sess??o. No futuro os estudos poderiam analisar os par??metros cardiovasculares induzidos pela dan??a por um maior per??odo p??s-exerc??cio.

The sample comprised 41 children and adolescents from both gender, aged between 9 and 19 years old, being 26 with DS from ???Espa??o ConViv??ncias??? Project and 15 volunteers without DS rated as control group (CG). Anthropometric measurements of height, weight, waist circumference and hip, BMI (Body Mass Index) and skinfold thickness were made, and to calculate the the body fat %G it was used four protocols and DEXA. Blood samples were taken for biochemical analysis also applying if you recall 24 hours food intake and the isometric strength test. It was observed that 40% of the control group showed overweight and obesity while in the DS group was detected the rate of overweight and obesity was 50%. The caloric intake in both groups was according to the daily recommendations, but protein intake was above recommended on both groups. The stature, strength and reason force had a significant difference P <0.05 corroborating previous studies where people with Down syndrome have a lower height and strength when compared to the general population. In biochemical analyzes significant changes were shown (P <0.05) to triiodothyronine (T3) between the GC and SD. It was observed that in the DS group in Jackson and Pollock protocol ICC (0.83), r (0.82) and R?? (0.86) and Slaugter ICC protocol (0.74), r (0.79) R2 (0.62) wherein the linear regression analysis indicated that most explanatory power with equation was followed by Jackson and Pollock et al Slaugter. The group with DS showed lower isometric strength when compared to the CG and predisposition to being overweight and even obesity, a problem that can be worsened by poor eating habits. It was concluded that the equations of Slaughter et al would be the most appropriate to determine the %G in children and teenagers with DS by requiring less knowledge from appraiser to perform it, because of the amount folds to be analyzed, requiring less time for implementation and readiness access to the folds. It was noticed, finally, that because this is the first Brazilian study on this subject, there is a need for further studies related to the prediction of body composition in children and teenagers with DS that could promote the development of a specific equation for this audience. / O objetivo desse trabalho foi avaliar o estado nutricional e fazer uma correla????o do uso dos diferentes protocolos de avalia????o da composi????o corporal mais utilizados, comparados com a absometria de raio-X de dupla energia ??? DEXA, em crian??as e adolescentes com S??ndrome de Down (SD). A amostra foi constitu??da 41 crian??as e adolescentes de ambos os sexos, com idade entre 9 e 19 anos, sendo 26 (com SD do Projeto Espa??o Com-Viv??ncias e 15 volunt??rios sem SD classificados como grupo controle (GC). Foram feitas medidas antropom??tricas de estatura, peso, circunfer??ncia de cintura e de quadril, IMC, dobras cut??neas e, para calcular o %G utilizou-se quatro protocolos e o DEXA. Foram realizadas coletas de sangue para an??lises bioqu??micas, aplicando-se ainda o recordat??rio de consumo alimentar de 24 horas e o teste de for??a isom??trica. Foi observado que 40% do GC apresentaram sobrepeso e obesidade enquanto no grupo com SD a taxa de sobrepeso e obesidade foi de 50%. A ingesta cal??rica nos dois grupos esteve de acordo com as recomenda????es di??rias, por??m o consumo de prote??nas esteve acima do recomendado para ambos os grupos. A estatura, for??a e raz??o for??a tiveram uma diferen??a significativa P<0,05 corroborando com estudos anteriores onde pessoas com SD apresentam menor estatura e for??a quando comparadas ?? popula????o em geral. Nas an??lises bioqu??micas foram apresentadas altera????es significativas (P<0,05) para triiodotironina (T3) entre o GC e SD. Foi observado que no grupo SD no protocolo de Jackson e Pollock ICC(0,83), r(0,82) e R??(0,86) e no protocolo de Slaugter ICC(0,74), r(0,79), R2(0,62) sendo que a an??lise de regress??o linear indicou que a equa????o com maior poder explicativo foi a Jackson e Pollock seguida de Slaugter et al. O grupo com SD apresentou menor for??a isom??trica quando comparado ao GC e predisposi????o a ter peso excessivo e at?? mesmo obesidade, problema que pode ser agravado pelos h??bitos alimentares inadequados. Concluiu-se que as equa????es de Slaughter et al seria a mais adequada para determinar o %G em crian??as e adolescentes com SD, por exigir uma menor capacita????o do avaliador para executa-la, pela quantidade menor de dobras a serem analisadas, demandando menor tempo para execu????o e facilidade de acesso as dobras. Percebeu-se, por fim, que por este ser o primeiro estudo brasileiro sobre este tema, h?? necessidade de novos estudos relacionados ?? predi????o de composi????o corporal de crian??as e adolescentes com SD que poderiam promover o desenvolvimento de uma equa????o espec??fica para este p??blico.

However, few studies have analyzed and associated the combination of family history, physical activity level, anthropometric profile and physical fitness on blood pressure reactivity and nitric oxide bioavailability in adolescents submitted to the Shuttle Run 20 meters, Cold Pressor Test and palmar grip strength. A total of 172 adolescents (n = 60???, n = 112???), high school students of the Technical College of Campinas-SP, aged 14 to 18 years, were classified into: normotensive children (FN; = 38???, n = 48???) and hypertensive children (FH; n = 22???; n = 64???), subdivided into active and sedentary. All procedures followed the ethical requirements of resolution 466/12 of the National Health Council. The results showed significant differences between FN vs. FH in several parameters of physical fitness, hemodynamic components and in salivary nitrite. Therefore, this study demonstrated that FH adolescents already present a negative influence of anthropometric, cardiovascular and physical activity levels on the bioavailability of salivary nitric oxide in children of hypertensive patients. / A hipertens??o arterial sist??mica ?? um problema mundial de sa??de, afetando inclusive a popula????o adolescente, nessa faixa et??ria, a predisposi????o gen??tica e as modifica????es biopsicossociais s??o importantes fatores no que tangem ao desenvolvimento da HAS.

In this place there is the permanent presence of different ethnicities that transit and perpass that territory. Before this reality and its complex frontier nuances (Brazil-Bolivia), the School Physical Education is discussed in this thesis, linked to the themes such as education, cultural diversity, interculturality, ethnicity, ethnocentrism, sport and body. It should be emphasized that the region studied is influenced by the various events (macro and micro) of the social, cultural, political and economic fields, creating a mosaic of approximations, exchanges, difficulties, frictions and constraints that permeate human relations at the border, which tend to be valued, stressed and/or shared by the people who live in that place. Thus, the present study seek to understand the School Physical Education in a frontier territory, that undergoes diverse influences of its own context, resulting from national and international laws, cultural, political/diplomatic, economic, social, ethnic factors. Considering processes of approximations and prejudices existing in the region, the general objective was to examine the ethnic aspects that permeate the pedagogical actions of the School Physical Education discipline, especially observing how teachers and students describe ??? the latter from different ethnicities and identities (in some cases hybrids) ??? on corporal practices in a border school. In methodological terms the research had as background the ethnography, especially considering the complexity of articulation between the Physical Education area and the different aspects of the frontier under study. We interviewed seven teachers and 20 students (Brazilian-Bolivians) from a municipal public school (CAIC), particularly close to the border (Brazil-Bolivia) and with a greater number of students living in Bolivia who do the pendulum movement to study in Brazil. Field survey data were collected through interviews that were previously structured (script) and analyzed qualitatively (discourse analysis). Subsequently, with the information of all interviewees, it was possible to compare intragroup data (teacher X teacher / student X student) and also between groups (teachers X students). We obtained, from this, the convergences and divergences between the discourses of the respondents, particularly on the issues related to intercultural education and the sociocultural aspects in the conduction of the Physical Education discipline in the frontier region. The data analyzed indicate that there is potential in the area to collaborate in overcoming possible discriminatory processes among students, also projecting new educational issues/concerns for Physical Education teachers and other undergraduate courses, especially for those who want to consider the intercultural education in regions with international border integration. / O presente trabalho foi desenvolvido na cidade de Corumb??, no estado de Mato Grosso do Sul (Brasil), um local fronteiri??o que faz intera????o particular com a Bol??via. Neste local, existe a presen??a permanente de diferentes etnias que transitam e perpassam aquele territ??rio. ?? diante desta realidade e suas complexas nuances fronteiri??as (Brasil-Bol??via) que a Educa????o F??sica escolar ?? discutida nesta tese, vinculada a temas como educa????o, diversidade cultural, interculturalidade, etnicidade, etnocentrismo, esporte e corpo. Ressalta-se que a regi??o estudada ?? influenciada pelos diversos acontecimentos (macro e micro) dos campos social, cultural, pol??tico e econ??mico, criando um mosaico de aproxima????es, trocas, dificuldades, fric????es e constrangimentos que permeiam as rela????es humanas na fronteira, as quais tendem a ser valoradas, tensionadas e/ou compartilhadas pelas pessoas que convivem naquele local. Assim, o presente estudo buscou compreender a Educa????o F??sica escolar em um territ??rio fronteiri??o, que sofre diversas influ??ncias do seu pr??prio contexto, decorrentes das leis nacionais e internacionais, de fatores culturais, pol??ticos/diplom??ticos, econ??micos, sociais e ??tnicos. Considerando os processos de aproxima????es e preconceitos existentes na regi??o, o objetivo geral foi examinar os aspectos ??tnicos que permeiam as a????es pedag??gicas da disciplina Educa????o F??sica escolar, especialmente observando como descrevem professores e alunos ??? estes de etnias e identidades distintas (em alguns casos h??bridas) ??? sobre as pr??ticas corporais numa escola fronteiri??a. Em termos metodol??gicos, a pesquisa teve como pano de fundo a etnografia, sobretudo considerando a complexidade de articula????o entre a ??rea de Educa????o F??sica e os diferentes aspectos da fronteira em estudo. Foram entrevistados sete professores e 20 alunos (brasileiros-bolivianos) de uma escola p??blica municipal (CAIC), particularmente pr??xima ?? fronteira (Brasil-Bol??via) e com maior n??mero de discentes residentes na Bol??via, que fazem o movimento pendular para estudar no Brasil. Os dados da pesquisa de campo foram coletados atrav??s de entrevistas previamente estruturadas (roteiro) e analisadas qualitativamente (an??lise de discurso). Posteriormente, com as informa????es de todos os entrevistados, foi poss??vel comparar os dados ???intragrupos??? (docente X docente / discente X discente) e tamb??m ???intergrupos???

However stressors present in air travel cause autonomic changes occur, requiring the body an ability to deal with these factors. Therefore preventive and/or mitigating strategies of these effects need to be understood. The study aims to evaluate the autonomic and cardiovascular responses that occur in flight and its relationship to physical fitness. The research was done through two studies, where healthy men had the components of physical fitness: aerobic capacity, muscular strength and body fat previously evaluated; and the registration of heart rate variability (HRV) performed in a control day and a flight day. The first study 11 fighter pilots reported 3h HRV and had the level of dehydration during a test flight measured by hematocrit change. The flight lasted 1 hour and all underwent the same operating procedures. The second study, 22 passengers of commercial aviation, recorded 24h HRV and blood pressure simultaneously. The results of the study show that a supersonic flight caused a reduction in most HRV parameters during flight when compared with the control day. There is no autonomic anticipation. Entropy correlated with aerobic capacity and body fat. Dehydration generated by the flight changed HRV (RMSSD and SD1). The second study demonstrates that the commercial flight caused a reduction in most HRV parameters during flight (RMSSD; SD1; SampEn; LnHF; 1), and in 24h when compared with control day (FC; LnHF; 2). There was autonomic anticipation. The blood pressure and Rate-Pressure Product were significantly higher on the flight, with the largest increases two hours before the flight and staying elevated for up to two hours. The lower the body fat percentage and BMI, the greater the HRV during the flight day (RMSSD; LF; HF; SD1). Already the aerobic capacity the higher, the greater the HRV during the flight (LnLF; LnHF). Conclusions: The flight, in both situations and people, demanded the body autonomic responses generating significant vagal withdrawal, an increase in heart rate. The body fat and aerobic capacity, indicators of physical fitness, correlated with HRV, however differently in the two populations and situations: fighter pilots (SampEn) and passengers of commercial aviation (RMSSD; LF; HF; SD1). Dehydration generated by supersonic flight influence on HRV. The blood pressure (SBP, DBP, MAP) is influenced by virtue of flight in comparison of 24h. The autonomic changes relating correlate with aerobic capacity and body fat differently in pilots of supersonic jets and passenger commercial aircraft undergoing flight. The relative strength was not correlated with HRV parameters in any of the populations studied. / A avia????o ?? o meio de transporte mais eficaz que existe na atualidade, atendendo a bilh??es de pessoas a cada ano. Contudo, os fatores estressantes presentes nos deslocamentos a??reos fazem que altera????es auton??micas e cardiovasculares ocorram, exigindo do organismo uma capacidade de lidar com estes fatores. Por isto estrat??gias preventivas e/ou minimizadoras desses efeitos precisam ser entendidas. O estudo buscou verificar as respostas auton??micas e cardiovasculares que ocorrem em voo e sua rela????o com a aptid??o f??sica. A pesquisa deu-se por meio de dois estudos, em que homens saud??veis tiveram os componentes da aptid??o f??sica (capacidade aer??bia, for??a muscular e gordura corporal) previamente avaliadas; e o registro da variabilidade da frequ??ncia card??aca (VFC) realizado em um dia controle e em um dia de voo. No primeiro estudo 11 pilotos de ca??a registraram 3h de VFC e tiveram o n??vel de desidrata????o mensurado durante um voo de teste avaliado pela mudan??a do hemat??crito. O voo durou 1h e todos realizaram os mesmos procedimentos operacionais. No segundo estudo, 22 passageiros da avia????o comercial registraram 24h de VFC e simultaneamente ?? press??o arterial. Os resultados do estudo 1 demonstra que o voo induziu uma redu????o na maioria dos par??metros da VFC durante o voo quando comparado com o dia controle, n??o havendo antecipa????o auton??mica. A entropia amostral da FC correlacionou-se com a capacidade aer??bia e a gordura corporal. A desidrata????o gerada pelo voo alterou a VFC. O estudo 2 demonstrou que o voo comercial induziu a uma redu????o na maioria dos par??metros da VFC durante o voo, e em alguns par??metros nas 24h quando comparado com o dia controle. Houve antecipa????o auton??mica uma hora antes do voo. A press??o arterial e duplo produto foram significativamente maiores no dia do voo, tendo os maiores incrementos duas horas antes do voo e mantendo-se elevados por at?? duas horas ap??s. Quanto menor o percentual de gordura e IMC, maior a VFC durante o dia do voo. Quanto mais elevada a capacidade aer??bia, maior a VFC durante o voo. Conclus??es: o voo, em ambas as situa????es e popula????es, exigiu do organismo respostas auton??micas gerando significativa retirada vagal, com incremento da frequ??ncia card??aca. A gordura corporal e a capacidade aer??bia, indicadores da aptid??o f??sica, correlacionaram-se com a VFC, contudo de forma diferente nas duas popula????es e situa????es. A desidrata????o gerada pelo voo militar influenciou na VFC. A press??o arterial (PAS; PAD; PAM) sofre interfer??ncia em virtude do voo na compara????o das 24h. As altera????es auton??micas se correlacionam com a capacidade aer??bia e gordura corporal de forma diferenciada em pilotos militares e passageiros da avia????o comercial submetidos ao voo.

However, there are no reports in the literature regarding the energy cost of exercise based on the method, especially when compare mat or equipment use. The aim of this study was to analyze and compare the energy cost, HR and BP in Pilates sessions in the mat and on the equipment. For this, were selected 18 volunteers to perform both Pilates sessions (mat and equipment), in different days. The variables analyzed were VO2 through indirect calorimetry, and subsequent calculation of the energy cost in METs and Kcal/min-1, blood lactate, HR and BP. ANOVA for repeated measures (Split-Plot) with post hoc Bonferroni analysis was used to compare the differences between the conditions and the level of significance was set at p <0.05. The results in the present study on mat condition can be classified as very light exercise with energy cost values of 1.9 ?? 0.2 METs and in the equipment condition with values of 2.6 ?? 0.3 METs. Likewise, have found a value of 1.9 Kcal/min-1 on the mat session, and 2.6 Kcal/min-1 on the equipment session. The VO2 remained elevated after exercise for both sessions, with significant values only for the mat (pre 3.1 ?? 0.8, post 4.3 ?? 0.7). The blood lactate concentration showed no significant increase after the end of the solo sessions and apparatus. HR analysis in this study confirmed the low intensity of Pilates sessions, average HR solo session remained at 53% of maximum heart rate, and the device session 49%. Systolic and diastolic BP did not present higher values in relation to the rest. It is suggested that a training program using this protocol with exercises based on the Pilates method is a choice for the initial stage of intervention in sedentary individuals, the elderly or those with cardiovascular disease. / Os exerc??cios de Pilates t??m ganhado espa??o como uma modalidade de exerc??cio n??o s?? na reabilita????o, mas tamb??m para melhora da sa??de geral. No entanto, n??o h?? relatos na literatura quanto ao custo energ??tico dos exerc??cios baseados no m??todo, em especial quando se utiliza solo ou aparelho. O objetivo do estudo foi analisar e comparar o custo energ??tico, a FC e a PA nas sess??es de Pilates no solo e no aparelho em mulheres saud??veis. Para isso, foram selecionadas 18 volunt??rias que realizaram duas sess??es de Pilates (solo e aparelho), em dias distintos. As vari??veis analisadas foram VO2, por meio da calorimetria indireta, e posterior c??lculo do custo energ??tico em METs e Kcal/min-1, lactato sangu??neo, FC e PA. ANOVA para medidas repetidas (Split-Plot) com an??lise post hoc e Bonferroni foi utilizado para comparar as diferen??as entre as condi????es, e o n??vel de signific??ncia adotado foi p <0,05. A sess??o realizada no presente estudo na condi????o solo pode ser classificada como exerc??cio de intensidade muito leve com valores de custo energ??tico de 1,9 ?? 0,2 METs e a condi????o aparelho como leve, com valores de 2,6 ?? 0,3 METs. Da mesma forma, foi encontrado um valor de custo de energia de 1,9 Kcal/min-1 na sess??o solo e 2,6 Kcal/min-1 na sess??o aparelho. Foi observado que o VO2 permaneceu elevado ap??s o exerc??cio para ambas as sess??es, com valores significativos apenas para o solo (pr?? 3,1 ?? 0,8; p??s 4,3 ?? 0,7). A concentra????o sangu??nea de lactato n??o apresentou aumento significativo ap??s o t??rmino das sess??es solo e aparelho. A an??lise da FC neste estudo reafirmou a baixa intensidade das sess??es de Pilates, a FC m??dia da sess??o solo permaneceu em 53% da FCm??x, e a sess??o aparelho a 49% A PA sist??lica e diast??lica n??o apresentaram maiores valores em rela????o ao repouso. Sugere-se que um programa de treinamento utilizando este protocolo com os exerc??cios baseados no m??todo Pilates seja uma escolha para o est??gio inicial de interven????o em indiv??duos sedent??rios, idosos ou aqueles que apresentam doen??as cardiovasculares.

Furthermore, other have shown that the rate of increase in core temperature may vary according to the exercise mode under consideration; in contrast to self-paced exercise, controled-pace exercise requires greater muscle recruitment, thereby inducing higher increase in core temperature. The aim of this study was to examine the acute effects of cranial-cervical cooling in the rate of increase of core temperature, and physiological and psychological responses during controlled-pace and self-paced exercises performed in hot environment. Methods: Ten cyclists took part in the study, they underwent 3 preliminary sessions under ~21 ??C and 4 experimental sessions in hyperthermia (~33 ??C), that is: self-paced exercise with or without central cooling (ESP33 e ESP33C); and controlled-pace exercise with or without central cooling (ECP33 e ECP33C). In both the exercise modes they completed 20km cycling trial either in a self-paced manner anchored in ratings of perceived exertion (RPE = 16), or in a controlled-pace manner with intensity set at the mean power output recorded during preliminary self-paced exercise session under ~21 ??C. Core and peripheral temperature, cardiopulmonary and perceptive measures were obtained during exercises, while maximal voluntary muscle torque, body mass and urine density were obtained prior and post exercises. Mean responses, as well as the rate of increase in core temperature and RPE along the exercises with or without cooling were compared. Results: The control trials showed that ESP e ECP were submaximal, and affected by the elevation in environment temperature (21 ??C vs 33??C). Regarding the responses to the cranial-cervical cooling, there were cooling main effects due to reduction in exercise time, increases in power output, reduction in mean core temperature and its rate of increase. Additionally, there was lower RPE and thermal sensation. Only the oxygen uptake showed exercise mode main effects, with greater values in ECP. No exercise mode by cooling interaction effects was observed. Conclusion: The central cooling was effective to increase the motor performance, likely due to the attenuated increase in core temperature and RPE. However, the exercise mode did not determine to these responses. / Introdu????o: Estudos anteriores observaram que o resfriamento central ?? efetivo para atenuar a taxa de eleva????o da temperatura central ao longo do exerc??cio realizado em hipertermia. Demonstram tamb??m, que a taxa de eleva????o da temperatura central pode depender do modelo de exerc??cio praticado; exerc??cios com ritmo controlado, ao contr??rio de exerc??cios com ritmo auto-ajustado, requerem maior recrutamento muscular e, consequentemente, apresentam maior eleva????o da temperatura central. O objetivo deste estudo foi examinar os efeitos agudos do resfriamento cr??nio-cervical sobre a taxa de eleva????o da temperatura central, respostas fisiol??gicas e perceptivas associadas, durante exerc??cios de ritmo auto-ajustado e ritmo controlado, realizados em ambiente quente. M??todos: Participaram do estudo dez ciclistas experientes e aclimatados ao calor, os quais foram submetidos a 4 sess??es preliminares em 21 ??C e 4 sess??es experimentais em hipertermia (33 ??C), a saber: exerc??cio com ritmo auto-ajustado sem e com resfriamento cr??nio-cervical (EAA33 e EAA33R); e exerc??cio com ritmo controlado sem e com resfriamento cr??nio-cervical (ECON33 e ECON33R). Em ambos os modelos, os participantes completaram 20 km; ou com ritmo auto-ajustado, controlado pela percep????o subjetiva de esfor??o (PSE = 16), ou ritmo controlado, em intensidade fixa, correspondente ?? intensidade m??dia gerada na sess??o preliminar de exerc??cio com ritmo auto-ajustado em 21 ??C. Medidas de temperatura central e perif??rica, cardiopulmonares e psicol??gicas foram obtidas durante a realiza????o dos exerc??cios, enquanto medidas do torque muscular volunt??rio m??ximo, massa corp??rea e densidade da urina, foram realizadas antes e ap??s os exerc??cios. Respostas m??dias e a taxa de modifica????o da temperatura retal (TR) e percep????o subjetiva de esfor??o (PSE) ao longo dos diferentes modelos de exerc??cio, sem e com resfriamento, foram comparadas. Resultados: Os testes controle evidenciaram que o EAA e ECON foram de intensidade subm??xima, e foram influenciados pelo aumento da temperatura ambiente (21 ??C vs 33??C). Quanto as respostas frente ao resfriamento cr??nio-cervical, foram verificados efeitos principais, em fun????o da redu????o do tempo total, eleva????o da pot??ncia mec??nica produzida, atenua????o da TR e de sua taxa de eleva????o; al??m da menor PSE (geral e local) e sensa????o t??rmica. Com rela????o aos efeitos principais do modelo de exerc??cio, somente o consumo de oxig??ncio foi modificado com maiores valores em ECON. Efeitos do resfriamento foram detectados sobre a TR e sua taxa de eleva????o, pois foram reduzidas em ambos os modelos de exerc??cio. Nenhum efeito de intera????o foi observado nas vari??veis medidas. Conclus??o: O resfriamento central foi efetivo na eleva????o do desempenho motor, possivelmente mediado por uma atenua????o da eleva????o da temperatura central e altera????o na PSE. Entretanto, o modelo de exerc??cio n??o foi determinante para a observa????o destas respostas.

Moreover, hypertension and diabetes coexist very frequently, as 60-65% of diabetics are hypertensive. The coexistence of hypertension and diabetes can reduce endothelium-mediated vasodilatation, which can be partially explained by a reduced production of nitric oxide (NO) or a decreased response to NO in the vascular smooth muscle. On the other hand, it has been shown that a single session of exercise can promote significant reductions in blood pressure (BP). This occurrence is known as post-exercise hypotension (PEH) and appears to be associated with the activity of the kallikrein-kinin system and release of NO. Although studies have observed PEH in individuais with T2D the molecular mechanisms have not been fully elucidated. ln addition, the prescription of exercise intensities based on lactate threshold (L T) has been suggested for individuais with T2D.Moreover, in spite of previous studies showing that individuais with T2D exhibit PEH when exercising at intensities around LT , There is evidence that subjects with T2D exhibit lower plasma kallikrein activity (PKA) compared to healthy individuais, suggesting that lower NO release and reduced endothelium-dependent vasodilation would be occurring in response to exercise for this population. However, no investigations were made on the integrated responses of PKA, BK, dessArg9-BK and NO and its association to the occurrence of PEH in individuais with or without T2D.Furthermore, to the best of our Knowledge, there is only one study that has investigated the effects of exercise (aerobic and / or resistance) on the 24-hour BP response in individuais with T2D. Not to mention that it is not of our knowledge, studies that have investigated the effects of different aerobic exercise intesities on BP 24 hours in subjects with T2D.Additionally, Several studies have investigated the effects of different exercise modes ( e.g., aerobic vs. resistance ), intensities, and durations on BP responses during the post-exercise recovery period. Studies regarding the effects of different sports modalities, especially martial arts, have also been performed, such as: Tai Chi Chuan, Jiu Jitsu, and Judo. However, until now, no study has explored the BP responses after a single Contact Karate (CK) session. It is worth mentioning that the scientific literature related to combat sports has hardly been explored, especially regarding health-related variables (i.e., post-exercise BP reduction). Most studies have investigated performance-related parameters in athletes, making the evaluation of health-related variables (such as PEH) a scientific gap. Therefore, investigations related to this issue have been strongly encouraged. It should be noted that given the known complications of type 2 diabetes and characteristics of sport (high physical contact of high impact), it is wise to initially investigate the effects of a contact karate session on the blood pressure response after exercise in apparently healthy subjects and then, if possible, in special populations as diabetes and hypertension. With regard to chronic exercise, in particular the resistance exercise, the available literature concerning their effects on the response of NO and, in tum, on BP in individuais with T2D, it is still incipient. To the best of our knowledge, there have been only two randomized clinical trials ofRT's effects on NO concentration and BP levels in T2D patients, only one of which, verified the NO response (along with BP) due to R T. Therefore, there is an apparent lack of evidence on R T' s effects on the responses of NO and BP in T2D patients. Objectives: Study 1) to investigate and compare the responses of PKA, BK, desArg9-BK, NO and BP after a single session of moderate-intensity aerobic exercise in T2D and non-diabetic (ND) individuais; study 2) To verify the effects of different intensities of aerobic exercise on 24-hour ambulatory BP responses in individuais with T2D and prehypertension; study 3) to verify the effects of a Contact Karate (CK) session on BP responses during a post-exercise recovery period in young adults; study 4) to determine the effects of eight weeks RT on the responses of NO and BP in T2D patients and their controls peers. Methods: study l)Ten subjects with T2D and 10 Non-diabetics (ND) underwent three sessions: 1) maximal incremental test on cycle ergometer to determine lactate threshold (L T); 2) 20- min of constant-load exercise on cycle ergometer, at 90% LT and; 3) control session. BP and oxygen uptake were measured at rest and at 15, 30 and 45 min post-exercise. Venous blood samples were collected at 15 and 45 minutes of the recovery period for further analysis of PKA, BK and desArg9-BK. NO was analyzed at 15 minutes post exercise. Study 2) ten individuals with T2D and prehypertension completed three sessions applied in random order: non-exercise control (CON) and exercise at moderate (MOD) and maximal (MAX) intensities. Heart rate (HR), BP, blood lactate concentrations ([Lac ]), oxygen uptake (VO2), and rate of perceived exertion (RPE) were measured at rest, during the experimental sessions, and during the 60 min recovery period. After this period, ambulatory blood pressure was monitored for 24 h. Study 2) ten individuals with T2D and prehypertension completed three sessions applied in random order: non-exercise control (CON) and exercise at moderate (MOD) and maximal (MAX) intensities. Heart rate (HR), BP, blood lactate concentrations ([Lac ]), oxygen uptake (VO2), and rate of perceived exertion (RPE) were measured at rest, during the experimental sessions, and during the 60 min recovery period. After this period, ambulatory blood pressure was monitored for 24 h. Study 3) Thirty-two male CK athletes volunteered and underwent one CK session (50 min) anda control session. BP was measured during rest (before sessions), as well as on the 15th, 30th, 45th, and 60th min of the post-exercise recovery. Study 4) We performed eight-weeks of randomized controlled trial in T2D patients and ND individuals. After initial screening, were randomly allocated into four groups: (1) trained T2D (T2DTRAINED; n = 9), (2) trained ND (NDTRAINED; n = 10), (3) control T2D (T2DCON; n = 8) and (4) control ND (NDCON; n = 7). NO and BP were determined before and after the intervention. Results: study 1) The ND group presented PEH of systolic blood pressure (SBP) and mean arterial pressure (MAP) on the 90% L T session but T2D group did not. Plasma NO increased ~24.4% for ND and ~13.8% for T2D group 15min after the exercise session. Additionally, only ND individuais showed increases in PKA and BK in response to exercise and only T2D group showed increased desArg9-BK production. Study 2) Compared with CON, only MAX elicited post-exercise BP reduction that lasted for 8 h after exercise and during sleep. Study 3) The SBP, diastolic blood pressure, and MAP were significantly lower at the post-exercise period compared to pre-exercise rest (p<.05), with the largest reductions being observed at the 60th min of recovery and at the sarne periods of post-exercise recovery of the control session. Study 4) After eight weeks of RT (three times per week), the T2D and ND experimental groups decreased systolic blood pressure (SBP) by 7.0 and 3.4 mmHg, respectively. However, the control groups showed maintenance (0.24 mmHg for T2D) or elevation (2.2 mmHg for ND) of systolic blood pressure. Although none of these changes were significant (p > .05). As regards the absolute values of BP, T2D subjects who did not undergo the training (T2DCON) tended (p = .057) to have increase SBP and significantly (p = .05) increased MAP. Conclusions: studyl) it was concluded that T2D individuals presented lower PKA, BK and NOx release as well as higher desArg9-BK production and reduced PEH in relation to ND participants after a single exercise session. Study 2) A single session of aerobic exercise resulted in 24 h BP reductions in individuals with T2D, especially while sleeping, and this reduction seems to be dependent on the intensity of the exercise performed. Study 3) a single CK session can promote a decrease in BP for at least 60 min after performing this type of exercise in young adults. Study 4) eight weeks of RT does not increase NO concentrations and, in tum, does not reduce BP in T2D patients-though it prevented its increase. / Introdu????o: o diabetes est?? associado com disfun????o endotelial, bem como com diversas desordens cardiovasculares, como hipertens??o arterial sist??mica (HAS). A HAS e o diabetes coexistem muito frequentemente. Aproximadamente, 60-65% dos diab??ticos s??o hipertensos. A coexist??ncia do diabetes e HAS pode reduzir a vasodilata????o endot??lio-dependente, que pode ser parcialmente explicada por uma reduzida produ????o ou resposta ao ??xido n??trico (ON) na nusculatura vascular lisa. Por outro lado, estudos t??m demonstrado que uma ??nica sess??o de exerc??cio pode promover redu????es significativas na press??o arterial (PA). Esta ocorr??ncia ?? conhecida como hipotens??o p??s-exerc??cio (HPE) e parece estar associada com a atividade do sistema calicre??na-cinina e libera????o do ON. Embora estudos tenham observado HPE em indiv??duos com diabetes tipo 2 (DT2), os mecanismos moleculares relacionados ?? sua ocorr??ncia n??o foram completamente elucidados. Adicionalmente, a prescri????o de intensidades de exerc??cio baseada em cargas relativas ao limiar de lactato (LL) t??m sido sugerida para indiv??duos com DT2. No entanto, apesar de estudos anteriores demonstrarem que os indiv??duos com DT2 apresentam HPE quando submetidos a exerc??cios em intensidades em torno LL . Existe evid??ncia que indiv??duos com DT2 apresentam menor atividade da calicre??na plasm??tica (ACP) em compara????o aos indiv??duos n??o diab??ticos, sugerindo uma menor libera????o de ON e redu????o da vasodilata????o endot??lio-dependente em resposta ao exerc??cio para essa popula????o. Contudo, para o nosso melhor conhecimento, ainda n??o foram realizadas investiga????es sobre as respostas integradas de ACP, bradicinina (BK), des-Arg9-bradicinina, ON e sua associa????o com a ocorr??ncia de HPE em indiv??duos com ou sem DT2. Ademais, salvo melhor ju??zo, existe apenas um estudo que tenha investigado os efeitos do exerc??cio f??sico (aer??bio e/ou resistido) sobre a resposta da PA de 24 horas em indiv??duos com DT2. Sem mencionar que tamb??m n??o ?? do nosso conhecimento, estudos que tenham investigado os efeitos de diferentes intensidades de exerc??cio aer??bio sobre a PA de 24 horas em indiv??duos com DT2. Somando a isso, diversos estudos t??m investigado os efeitos de diferentes modos de exerc??cio (aer??bio vs. resistido), intensidades, e dura????es, sobre as respostas da P A p??s-exerc??cio. Estudos sobre os efeitos de diferentes modalidades esportivas, especialmente artes marciais, tamb??m foram realizados, tais como: Tai Chi Chuan, Jiu Jitsu e Jud??. Contudo, at?? o presente momento, nenhum estudo investigou a resposta da P A ap??s uma ??nica sess??o de Carat?? de contato (CC). Vale ressaltar que a literatura cient??fica relacionada a esportes de combate t??m sido pouco explorada, especialmente em rela????o ??s vari??veis relacionadas com a sa??de ( ou seja, a redu????o da PA p??s-exerc??cio). A maioria dos estudos investigaram os par??metros relacionados com o desempenho em atletas, tornando a avalia????o de vari??veis relacionadas com a sa??de, uma evidente lacuna cient??fica. Portanto, investiga????es relacionadas a este assunto t??m sido fortemente encorajada. Cabe salientar que, dado as conhecidas complica????es do DT2 e as caracter??sticas da modalidade em quest??o ( elevado contato f??sico de alto impacto), torna-se prudente inicialmente investigar os efeitos de uma sess??o de CC sobre a resposta da P A p??s-exerc??cio em indiv??duos aparentemente saud??veis e posteriormente, se poss??vel, em popula????es especiais como diab??ticos e hipertensos. No que se refere ao exerc??cio cr??nico, em particular sobre o exerc??cio de for??a, a literatura dispon??vel a respeito dos seus efeitos sobre a resposta do ON e, por sua vez, sobre a PA em indiv??duos com DT2, ainda ?? muito incipiente. Para o melhor do nosso conhecimento, existem apenas dois ensaios cl??nicos randomizados sobre os efeitos do treinamento resistido (TR) sobre a resposta do ON e P A em pacientes com DT2, dos quais apenas um, verificou a resposta do ON juntamente com a P A frente ao TR. Portanto, h?? uma aparente falta de evid??ncias a respeito dos efeitos do TR sobre as respostas do NO e PA em pacientes com DT2. Objetivos: estudo 1) investigar e comparas as respostas de ACP, BK, desArg9-bradicinina, ON e PA ap??s uma ??nica sess??o de exerc??cio aer??bio realizada em intensidade moderada (90% da carga de LL) em indiv??duos com e sem DT2; estudo 2) verificar e comparar os efeitos de uma ??nica sess??o de exerc??cio aer??bio sobre a resposta da PA de 24 horas e verificar os efeitos da intensidade do exerc??cio aer??bio sobre a resposta da PA 24 h em indiv??duos com DT2 e pr??-hipertensos; estudo 3) avaliar os efeitos de uma ??nica sess??o de CC sobre a resposta da PA p??s-exerc??cio em adultos jovens; estudo 4) investigar os efeitos de oito semanas de TR sobre as respostas de ON e P A em pacientes com DT2 e seus pares controles. M??todos: estudo 1) Dez indiv??duos com e DT2 e 10 n??o diab??ticos (ND) foram submetidos a tr??s sess??es: 1) teste incremental m??ximo em bicicleta ergom??trica para determinar o limiar de lactato (LL); 2) 20 min de exerc??cio de carga constante em cicloerg??metro, em 90% L T e; 3) sess??o controle. PA e consumo de oxig??nio foram mensurados em repouso e aos 15, 30 e 45 min p??s-exerc??cio. Amostras de sangue venoso foram coletadas em 15 e 45 minutos do per??odo de recupera????o para posterior an??lise de ACP, BK e desArg9- bradicinina. ON foi analisado aos 15 minutos ap??s o exerc??cio. Estudo 2) Dez indiv??duos com diabetes tipo 2 e pr??-hipertens??o foram submetidos a tr??s sess??es aplicadas em ordem rand??mica: 1) controle ( CON), sem exerc??cio e exerc??cio em intensidades moderadas (MOD) e m??xima (MAX). A frequ??ncia card??aca (FC), P A, as concentra????es de lactato sangu??neo ([Lac ]), consumo de oxig??nio (V02) e taxa de percep????o de esfor??o (TPE) foram coletados em repouso, durante as sess??es experimentais e durante o per??odo de recupera????o de 60 min. Ap??s esse per??odo, a P A de 24 h foi monitorada. Estudo 3) Trinta e dois atletas CC foram submetidos a uma sess??o de CC (50 min) e uma sess??o CON. A PA foi medida durante o repouso, bem como aos 15, 30, 45 e 60 min da recupera????o p??s-exerc??cio. Estudo 4) Foi realizada oito semanas de estudo randomizado controlado em pacientes DT2 e ND). Ap??s a triagem inicial, foram distribu??dos aleatoriamente em quatro grupos: (1) treinados com DT2 (TREINADODT2; n = 9), (2) treinados ND (TREINADOND; = n 1 O), ( 3) controle DT2 (CON DT2; n = 8) e (4) controle ND (CONND; n = 7). NO e BP foram determinadas antes e ap??s a interven????o. Resultados: estudo 1) somente o grupo n??o diab??tico (ND) apresentou HPE para press??o arterial sist??lica e press??o arterial m??dia na sess??o LT 90%. O ON plasm??tico aumentou ~ 24,4% no grupo ND e ~ 13,8% para o DT2 15 min ap??s a sess??o de exerc??cios. Al??m disso, apenas os indiv??duos ND mostraram aumentos de ACP e BK em resposta ao exerc??cio e somente os DT2 mostraram um aumento da produ????o desArg9-bradicinina. estudo 2) Ademais, comparado com a sess??o CON, somente a sess??o de exerc??cio MAX apresentou HPE, que durou at?? 8 h ap??s o exerc??cio e durante o sono. estudo 3) Em rela????o ao CC, a press??o arterial sist??lica (PAS), diast??lica (PAD) e press??o arterial m??dia (MAP) foi significativamente menor no per??odo p??s-exerc??cio em rela????o ao pr??-exerc??cio repouso, bem como em rela????o a sess??o CON, com as maiores redu????es sendo observadas aos 60 min de recupera????o. estudo 4) Ap??s oito semanas de RT, ambos os grupos experimentais (DT2 e ND), apresentaram diminui????o da PAS em 7,0 e 3,4 mmHg, respectivamente. No entanto, os grupos controle (DT2 e ND) demonstrou manuten????o (0,24 mmHg para DT2) ou eleva????o (2,2 mmHg para ND) da PAS. Embora nenhuma das mudan??as foram significativas (p> 0,05). Conclus??es: estudol) concluiu-se que os indiv??duos comDT2 apresentaram menor libera????o ACP, bradicinina e ON, bem como maior produ????o desArg9-bradicinina e reduzida HPE em rela????o aos participantes do grupo ND ap??s uma ??nica sess??o de exerc??cio. Estudo 2) uma ??nica sess??o de exerc??cio aer??bio resultou em redu????o da PA de 24 h em indiv??duos com DT2, especialmente durante o sono, e esta redu????o parece ser dependente da intensidade do exerc??cio realizado. Estudo 3) uma ??nica sess??o CC pode promover uma diminui????o da PA durante pelo menos 60 minutos depois de realizar este tipo de exerc??cio em adultos jovens. Estudo 4) oito semanas de TR n??o aumenta as concentra????es de ON e, por sua vez, n??o reduz a P A em indiv??duos com DT2, por??m parece impedir o seu aumento.

We aimed to verify and compare the waveform of N450 ERP component in Stroop task between active play, passive play and control sessions in children. 13 girls and boys (9.5??0.8yr; 32.05??5.9kg; 1.38??0.1m; 16.36??4.2%body fat) participated on this study. Firstly, they were performed anthropometric evaluations. Thereafter, three sessions lasting 30min were performed in randomized order: 1) Control ??? seated watching a documentary (92.4??8.9bpm); 2) Active Play ??? games with movement, eg. jumping jacks, running, jumping (152.8??16.31bpm); 3) Passive Play ??? playing games seated, eg. puzzles of colors, animals and numbers (99.6??28.2bpm). Subsequently, they completed a Stroop task (GO/No-go) while brain electrical activity was recorded with EEG. ERPs were recorded and calculated from electrodes at Fz, F3, F4, Fp1 and Fp2. Mean peak amplitude of N450 component were used to compare the electrical brain responses between sessions. The ANOVA of N450 mean amplitudes revealed a significant main effect for interaction of factor frontal anterior in control sessionF(2,36) = 3.63, p = 0.04 (fig 1). The N450 amplitude in the incongruent condition was less negative in active play than in control session in the frontal sites (p=0.11). In the Stroop test, no significant differences in reaction time between sessions were observed (F (1.92) = 0.05, p = 0.94). The control differed in congruent Go responses between the passive and active sessions (p = 0.01), and the results of the active session also differed from the passive (p = 0.04). The comparison of total errors per session also presented a significant difference (p = 0.02) between control and passive (F (1,71) = 8.8, p <0.05). In conclusion, 30 minutes of active play promoted a lesser response conflict in the incongruent stimuli in the Stroop test, in the N450 component, in addition to a greater activation of the prefrontal cortex. / A atividade f??sica e cogni????o s??o ??reas que est??o cada vez mais correlacionadas. O estudo objetivou verificar e comparar os efeitos agudos de brincadeiras ativas, passivas e controle na modula????o da onda N450 em escolares. 13 escolares de ambos os sexos (9,5??0,8anos; 32,05??5,9kg; 1,38??0,1m; 16,36??4,2%G) participaram de tr??s sess??es com dura????o de 30min em ordem randomizada: 1) Controle ??? sentadas assistindo um document??rio (92,4??8,9bpm); 2) Brincadeiras Ativas ??? brincadeiras com saltos, polichinelos e corrida (152,8??16,31bpm); 3) Brincadeira Passiva ??? brincando sentados com jogos pedag??gicos. Ap??s isso, realizaram o teste de Stroop (GO/No-go) enquanto era adquirida a atividade el??trica cerebral atrav??s de um eletroencefalograma (EEG) e registrado o potencial relacionado a evento (PRE), calculado pelos eletrodos Fz, F3, F4, Cz, Fp1 e Fp2. A ANOVA apresentou signific??ncia na m??dia do pico de amplitude da N450, com rela????o a intera????o do fator frontal anterior na sess??o controle F(2,36)= 3,63, p= 0,04. Na condi????o incongruente a amplitude da N450 foi menos negativa nos eletrodos frontais nas brincadeiras ativas comparada com controle (p=0,11). J?? no teste de Stroop, n??o foram observadas diferen??as significativas do tempo de rea????o entre as sess??es (F(1,92)=0,05, p=0,94). O controle diferiu nas respostas congruentes Go entre as sess??es passiva e ativa (p=0,01), e os resultados da sess??o ativa tamb??m diferiram da passiva (p=0,04). A compara????o do total de erros por sess??o tamb??m apresentou diferen??a significativa (p=0,02) entre controle e passiva (F(1,71)=8,8,p<0,05). Em conclus??o, 30 min de brincadeiras ativas promoveram menor conflito de resposta no teste de Stroop, no componente N450, com isso menor conflito de resposta no teste de Stroop nos est??mulos incongruentes, al??m de maior ativa????o do c??rtex pr??-frontal.
