Neuroexcitatory, metabolic, cardiovascular and even inflammatory responses may become hyperreactive to these situations, increasing the chances of diverse physiological dysfunctions, especially cardiovascular ones. It has been shown that a single exercise session performed prior to stress situations may be useful in attenuating blood pressure hyperreactivity to stress. Among the methods applied to evaluate cardiovascular reactivity to stress, is the cold pressure test (CPT). However, heart rate variability (HRV) responses to CPT have been poorly investigated. Although there is evidence that a higher level of physical fitness is related to a lower reactivity to stress, the relationship between muscle strength levels and cardiovascular reactivity to CPT has not been investigated yet. The aim of this study was to investigate the autonomic and cardiovascular responses to CPT in individuals with different levels of manual grip strength. This is a study where the use of questionnaire techniques, anthropometric measurements, hemodynamic measurements, neuromuscular evaluation, cardiovascular and autonomic reactivity to an induced stress test were used. A total of 57 male subjects aged 18 to 30 years participated in the study. After this evaluation and general procedures, volunteers were divided into tertiles by their relative manual grip strength level. The lower strength group (BF) presented higher values of body mass, body mass index (BMI), body fat and waist-to-height ratio compared to the mean strength (MS) and high strength (HS) groups. Regarding the cardiovascular reactivity to CPT, the three groups presented similar variation of blood pressure (BP), with systolic blood pressure (SBP) increasing significantly during CPT and decreasing during recovery until the third minute. Mean arterial pressure (Dampney et al.) showed higher values during CPT and lower in the third minute of recovery, which was also lower than the resting values for the FB group. Autonomic reactivity, as measured by HRV, demonstrated a discrepant behavior between the groups. During the CPT, subjects with lower manual grip relative strength had an BP response similar to the medium and high manual grip relative strength groups, but with greater sympathetic activation. / A sociedade moderna tem sido cada vez mais exposta a situa????es de estresse di??rias. As respostas neuroexcitat??rias, metab??licas, cardiovasculares e mesmo inflamat??rias podem se tornar hiper-reativas a essas situa????es, aumentando as chances de disfun????es fisiol??gicas diversas, em especial cardiovasculares. Tem sido demonstrado que uma ??nica sess??o de exerc??cio realizada antes das situa????es de estresse pode ser ??til para atenuar a hiperreatividade da press??o arterial ao estresse. Entre os m??todos aplicados para avaliar a reatividade cardiovascular ao estresse, esta o cold pressor test (CPT). No entanto, as respostas da variabilidade da frequ??ncia card??aca (VFC) ao CPT t??m sido pouco investigadas. Embora existam evid??ncias de que um maior n??vel de aptid??o f??sica esteja relacionado a uma menor reatividade ao estresse, a rela????o entre os n??veis de for??a muscular e a reatividade cardiovascular ao CPT ainda n??o foi investigada. O estudo teve como objetivo investigar as respostas auton??micas e cardiovasculares ao CPT em indiv??duos com diferentes n??veis de for??a de preens??o manual. Trata-se de um estudo onde se utilizou de t??cnicas de aplica????o de question??rios, tomada de medidas antropom??tricas, hemodin??micas, avalia????o neuromuscular, reatividade cardiovascular e auton??mica a um teste de estresse induzido. Participaram do estudo 57 sujeitos do sexo masculino com idades entre 18 a 30 anos. Ap??s esta avalia????o e os procedimentos gerais, os volunt??rios foram divididos em tercis pelo seu n??vel de for??a relativa de preens??o manual. O grupo baixa for??a (FB) apresentou valores mais elevados de massa corporal, ??ndice de massa corporal (IMC), gordura corporal e rela????o cintura-estatura em compara????o com os grupos m??dia for??a (FM) e elevada for??a (FE). Quanto ?? reatividade cardiovascular ao CPT, os tr??s grupos apresentaram varia????o similar da press??o arterial (PA), com valores de press??o arterial sist??lica (PAS) aumentando significativamente durante o CPT e diminuindo durante a recupera????o at?? o terceiro minuto. A press??o arterial m??dia (PAM) demonstrou valores mais altos durante o CPT e inferior no terceiro minuto de recupera????o, o que tamb??m foi menor do que os valores de repouso para o grupo FB. A reatividade auton??mica, medida pela VFC, demonstrou um comportamento discrepante entre os grupos. Durante o CPT os indiv??duos com for??a relativa de preens??o manual inferior apresentaram resposta PA semelhantes aos grupos de for??a relativa de preens??o manual m??dia e alta, mas com maior ativa????o simp??tica.

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.

Foram avaliados 172 adolescentes (n=60???; n=112???), alunos do ensino m??dio do Col??gio T??cnico de Campinas-SP, com idades variando entre 14 e 18 anos, os quais foram classificados em: filhos de normotensos (FN; n=38???; n=48???) e filhos de hipertensos (FH; n=22???; n=64???), subdivididos em ativos e sedent??rios. Todos os procedimentos seguiram as exig??ncias ??ticas da resolu????o 466/12 do conselho nacional de sa??de. Os resultados demonstraram diferen??as significativas entre FN vs. FH em diversos par??metros de aptid??o f??sica, componentes hemodin??micos e no nitrito salivar. Portanto, este estudo demonstrou que adolescentes FH j?? apresentam uma influ??ncia negativa de vari??veis antropom??tricas, cardiovasculares e n??vel de atividade f??sica na biodisponibilidade de oxido n??trico salivar em filhos de hipertensos.

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??? (docentes X discentes). Obtiveram-se, dessa forma, converg??ncias e diverg??ncias entre os discursos dos pesquisados, particularmente sobre as quest??es ligadas ?? educa????o intercultural e aos aspectos socioculturais na condu????o da disciplina Educa????o F??sica em regi??o de fronteira. Os dados analisados indicam existir potencialidades da ??rea para colaborar na supera????o dos poss??veis processos discriminat??rios entre os alunos, projetando tamb??m novas quest??es-preocupa????es educativas para os professores de Educa????o F??sica e aos demais cursos de forma????o superior em licenciatura, especialmente para os que pretendem considerar o tema da educa????o intercultural em regi??es com integra????o fronteiri??a internacional.

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.

In order to achieve such goals, a psycho-sociological approach as well as Social Representations and Central Nucleus theories were used. It was concluded with the collection of nuclear and peripheral structural elements, and with the realization of the anchorage of the social representation under study. Ninety volunteer health professionals who work in Teaching and Health Institutions in the Federal District were interviewed. Two research instruments were used. The first one was a questionnaire in order to collect data regarding the multidisciplinary health teams which exist at the researched institutions themselves. The second one was an interview in which the free association technique was used. The inducing term was ???the Physical Education professional???. The data collected was processed by the Evoc (Ensemble de Programmes Permettant l'Analyse des ??vocations) software and later analyzed by the researcher. As a result, it was identified that the images of ???healthy??? and ???physical conditioning??? naturally appeared in the social representations of the Physical Education professional built by health professionals. It was clearly identified that health, physical conditioning, and physical activities are socially as well as historically linked with the Physical Education professional. Those associations with a positive aspect probably will lead to favorable attitudes, not making it difficult for the Physical Education professional to have access to multidisciplinary health teams. / O presente estudo teve como objetivo identificar as representa????es sociais do profissional de educa????o f??sica constru??das por profissionais de sa??de a fim de determinar suas concep????es e inferir suas pr??ticas.

Foram entrevistados noventa profissionais de sa??de, volunt??rios, que atuam nas Institui????es de Ensino e de Sa??de do Distrito Federal. Foram utilizados dois instrumentos de pesquisa, sendo o primeiro um question??rio para captar informa????es a respeito das equipes multidisciplinares de sa??de existentes nas pr??prias institui????es pesquisadas e o segundo uma entrevista na qual se utilizou a t??cnica livre, tendo como termo indutor ???o profissional de educa????o f??sica???. O dados colhidos foram processados pelo software Evoc (Ensemble de Programmes Permettant l'Analyse des ??vocations) e analisados posteriormente pelo pesquisador. Como resultado, identificou-se que as imagens de ???sa??de??? e ???condicionamento f??sico??? surgiram espontaneamente nas representa????es sociais do profissional de educa????o f??sica, elaboradas pelos profissionais de sa??de. Identificou-se claramente que a sa??de, o condicionamento f??sico e as atividades f??sicas est??o social e historicamente associadas ao profissional de educa????o f??sica. Essas associa????es de aspectos positivos provavelmente conduzir??o a atitudes favor??veis, n??o dificultando o acesso do profissional de educa????o f??sica ??s equipes multidisciplinares de sa??de.

Although the exact moment when men started dancing isn???t known, by investigating the dance world in its different moments and spaces, it is possible to realise that their presence in this bodily practice is as old as the emergency of the practice in human history. Several are the affirmatives concerning men who dance, which opens a complex and almost unlimited field of research and analysis regarding the experiences lived by them. The prejudice, recognized as a an autonomous scientific field studied by the social psychology, is constant in the daily routine of these individuals, thus, a holistic view upon this subject must be built, therefore, the comprehension of the prejudice origins is necessary because only from there it will be possible to identify the propagation patterns on a social level, the contributing psychocognitive factors, and elaborate coherent and consistent interventions. With the objective of comprehending the social representations referring to the male participation in the dance universe, as well as identifying the stereotypes, prejudices, labels and discrimination reported by them, in order to amplify and solidify a holistic and informed view about the experience in this diverse artistic language under the perspective of the men who dance, this study - through a Quali quantitative Approach, of Applied Nature, Explanatory and Descriptive Features, based on Social Representation Research - investigates ballet male dancers working in Brasilia/DF and, by using content analysis and the IRAMUTEQ software, proposes reflections about the social dynamics lived by these dancers. It was concluded, under the perspective of ballet male dancers about the social representations surrounding this theme, the existence of representative words freely associated to them: ???Gay/Sensitive??? are negative stereotypes frequently attributed to them; in the other hand, ???Artist/Delivery??? even when not fully understood, present positive significance; and ???Brave/Strong??? can be classified as neutral stereotypes, however, in the dancers speech, these words are used to refer to behaviours of confrontation against the discrimination experienced by them. It was also noted that the main motivation to dance, described by the interviewed ballet male dancers, was the feeling of freedom that comes from the opportunity of detaching themselves from a reality often full of prejudices that invalidates the free movimentation and expression and that promotes behavioural patterns to several groups, turning any deviation in a motive for disapproval and, consequently, discrimination. / A cortina se abre expondo um grande espet??culo, no qual as diversas esferas de trabalho confluem para a realiza????o da apresenta????o, e no qual s??o estabelecidas percep????es e din??micas diferentes em cada um de seus ambientes - plateia, palco, coxias e bastidores -. Apesar de n??o se saber ao certo quando o homem come??ou a dan??ar, ao investigar o mundo da dan??a em diferentes momentos e espa??os, percebe-se que o seu aparecimento nessa pr??tica corporal ?? t??o antigo quanto o surgimento da pr??tica no in??cio da hist??ria da humanidade. Diversas s??o as afirmativas referentes aos homens que dan??am, sendo esse um assunto complexo e de propor????es quase ilimitadas por possibilitar diversos campos de an??lise acerca das experi??ncias por eles vivenciadas. O preconceito, reconhecido como conhecimento cient??fico aut??nomo estudado pela psicologia social, se faz uma constante no cotidiano desses indiv??duos, portanto, para que se tenha uma vis??o hol??stica sobre preconceito, ?? necess??rio que se compreenda sua origem, pois apenas a partir dela pode-se identificar os padr??es de propaga????o a n??vel social e os aspectos psico-cognitivos contribuintes, e ent??o elaborar interven????es coerentes e consistentes. Objetivando, ent??o, identificar os estere??tipos, preconceitos e discrimina????es referentes a participa????o masculina no universo da dan??a, sob a perspectiva dos bailarinos, no intuito de compreender as representa????es sociais de uma espec??fica companhia de dan??a profissional de Bras??lia/DF, esse estudo - atrav??s de uma abordagem qualiquantitativa, de natureza aplicada, car??ter explorat??ria e descritiva, pautada na pesquisa de representa????o Social, dentro de um estudo de caso - investiga bailarinos atuantes em Bras??lia/DF e, utilizando-se da an??lise de conte??dos e do software IRAMUTEQ, prop??e reflex??es acerca da din??mica social por eles vivenciada. Conclui-se, sob a perspectiva dos homens que dan??am acerca das representa????es sociais em torno desse tema, que pode-se constatar a exist??ncia de palavras associadas livremente aos bailarinos: ???Viado, Sens??vel??? s??o estere??tipos mais frequentemente associados negativamente a eles; por outro lado, ???Artista, Entrega???, mesmo que com entendimentos distorcidos, t??m car??ter mais positivo; e ???Corajoso, Forte??? podem ser classificadas como neutras, entretanto, no discurso dos bailarinos, serem implementadas como atitudes de enfrentamento ??s discrimina????es por eles vivenciadas. Notase, tamb??m, que o principal motivo para dan??ar, relatado pelos bailarinos pesquisados, ?? a sensa????o de liberdade de poder se desvencilhar de uma realidade muitas vezes marcada por preconceitos que inviabilizam a livre movimenta????o/express??o e que incitam padr??es de comportamentos para diversificados grupos, tornando quaisquer desvios motivo para desaprova????o e, consequentemente, discrimina????o.

The identification of cardiovascular risk in elderly asymptomatic lacks appropriate tools. From this perspective, brief physical tests have several advantages when compared to long distance and/or that require maximum effort. Although the walking speed test (WS) is a potential candidate, the consolidation of data is needed from multiple studies to determine comparative references. The aim of this study is perform a systematic review of literature examining associations between WST measures with traditional risk markers and cardiovascular events in people aged > 60 years and living on community. The methodology used search in Medline/PubMed and Scopus databases (??? December 2014). We selected 15 studies with population of 29.845 old people, that showed significant associations between WS, the risk (coronary calcification, C-reactive protein, hypertension, diabetes and medium intimal thickening) and cardiovascular events (death, peripheral arterial disease and stroke brain). Approximately 80% of the distance studies adopted ??? 6 meters and WS in the usual rate. High variability was observed in the results from the usual WST (0.8 - 1.3 m/s) and WST max. (1.1 - 1.6 m/s). Growing evidences reinforces the importance of the WST for the evaluation and the monitoring of cardiovascular health in the elderly. However, the variability of results and the diversity of protocols suggests cautious about generalizations of WST thresholds. / A doen??a cardiovascular (DCV) persiste como principal causa de ??bitos nas faixas et??rias mais elevadas. ?? imprescind??vel que novas medidas subcl??nicas possam identificar fatores de risco e predizer eventos cardiovasculares. Nessa perspectiva, breves testes f??sicos apresentam in??meras vantagens quando comparados ??queles de longa dist??ncia e/ou que demandam de esfor??o m??ximo. Embora o teste de velocidade de caminhada (VC) seja candidato potencial, ?? necess??ria a consolida????o de dados a partir de m??ltiplos estudos para a determina????o de refer??ncias comparativas e investigar se h?? a associa????o entre o teste de velocidade de caminhada com tradicionais fatores de risco e eventos cardiovasculares. O presente estudo teve como objetivo realizar uma revis??o sistem??tica de literatura, examinando associa????es entre medidas de VC com tradicionais marcadores de risco e eventos cardiovasculares em popula????es com faixa et??ria > 60 anos e n??o institucionalizados. A metodologia iniciou de pesquisa eletr??nica de estudos publicados nas bases de dados MEDLINE/Pubmed e SCOPUS, at?? Dezembro de 2014. Foram selecionados 15 estudos, com popula????o nos estudos de 29.845 idosos que evidenciaram importantes associa????es entre a VC, o risco (calcifica????o coronariana, prote??na C-reativa, hipertens??o, diabetes e espessamento m??dio intimal) e eventos cardiovasculares (mortalidade, doen??a arterial perif??rica e acidente vascular cerebral). Cerca de 80% dos estudos adotou dist??ncia ??? 6 metros e VC em ritmo usual. Observou-se elevada variabilidade nos resultados da VC usual (0,8 ??? 1,3m/s) e VC m??x. (1,1 ??? 1,6m/s). Crescente corpo de evidencias refor??a a import??ncia do teste de VC como instrumento simples, seguro e de reduzido custo para a avalia????o da sa??de cardiovascular em idosos. Entretanto, a variabilidade dos limiares de velocidade e a diversidade de protocolos entre os estudos sugerem cautela quanto a generaliza????es dos resultados para diferentes popula????es geri??tricas.

Pesquisa do Estado da Bahia - FAPEB / Bromelain is an enzyme complex with great therapeutic importance attributed both to it?s proteolytic activity, as the non-proteolytic components in the extract. Thus, the enzyme was extracted from different parts of Ananas comosus var comosus, from two pineapple with different codes: BGA 771 and BGA 772. The proteolytic and specific activities of bromelain from each part (stem, crown, peel, pulp and leaves) were investigated as well as their kinetic characteristics by measuring the optimum temperature and the optimum pH, and finally was studied it?s effect in vitro on murine melanoma B16F10 cells. In BGA 771, the highest proteolytic activity was found in the stem (81.10 mg/mL/min), while the highest specific activity was found in the pulp and peel (1983.44 and 1822.33 UA/mg of bromelain, respectively). In general, the optimum temperature varied between of 50 to 80 ?C and pH between 6 and 8. Bromelain all parts were effective more than 50% in inhibiting the melanoma B16F10 cells proliferation after 48 hours. The most significant inhibition was find on crown bromelain with 72.86%, and a time-dependent effect was observed on crown bromelain. At BGA 772 the higher activity was find in the pulp (35.58 mg/mL/min and 1446.60 UA/mg bromelain). The optimum temperature in the extracts ranged between 40 and 90 ?C, while the pH 6 was the best for all parties, while the leaf bromelain had two great points: 6 and 8. Only the bromelain peel was able to inhibit the melanoma B16F10 proliferation of, being 66.37% after 48 hours of contact, and a dose-dependent activity was observed. / A bromelina ? um complexo enzim?tico de grande import?ncia terap?utica, atribu?da tanto ? sua atividade proteol?tica, como aos componentes n?o proteol?ticos contidos no extrato. Dessa forma, a enzima foi extra?da de diferentes partes de Ananas comosus var comosus, a partir de dois abacaxizeiros com identifica??es distintas: BGA 771 e BGA 772. Foram investigadas as atividades proteol?tica e espec?fica da bromelina de cada parte (caule, coroa, casca, polpa e folha), bem como suas caracter?sticas cin?ticas atrav?s da medida da temperatura e do pH ?timos, investigando-se, por fim, o seu efeito in vitro sobre c?lulas tumorais de melanoma murino B16F10. No BGA 771, a maior atividade proteol?tica foi encontrada no caule (81,10 ?g/mL/min), enquanto a maior atividade espec?fica foi encontrada na polpa e na casca (1983,44 e 1822,33 UA/mg de bromelina, respectivamente). De um modo geral, a temperatura ?tima variou entre as partes de 50 a 80 ?C e o pH ?timo entre 6 e 8. A bromelina de todas as partes foi eficaz em inibir a prolifera??o das c?lulas de melanoma B16F10 ap?s 48 horas em mais de 50%, sendo a da coroa a mais significativa, com 72,86% de inibi??o, tendo sido observada uma atividade tempo-dependente. No BGA 772, as maiores atividade foram encontradas na polpa (35,58 ?g/mL/min e 1446,60 UA/mg de bromelina). A temperatura ?tima nos extratos variou entre 40 e 90?C, enquanto o pH 6 foi o melhor para todas as partes, exceto para a folha que teve dois pontos ?timos: 6 e 8. Somente a bromelina da casca foi capaz de inibir a prolifera??o do melanoma B16F10, sendo de 66,37% ap?s 48 horas de contato, tendo sido observada uma atividade dose-dependente.

The problem that guided the reflexion and the analysis of the presented topic involves constant worries and reflexions about the process of evaluation of the educational learning, emphasising the learning assessment in higher education: Teaching as an including or excluding practice?. Several discussions were sparked involving the evaluation of the teaching and learning process over the years, both in the educational field and in the Physical Education area as well. This process has undergone several changes due to the structural changes in society, the changes in human behavior, the scientific and technological progress, among other factors. In order to have a more significant assessment form, new meanings were being incorporated to this process, trying , this way to eradicate the traditional evaluation method used before. The methodology assumes a qualitative research.The method used for data collection was a semi-structured questionnaire composed of ten questions, both opened and closed.Data analysis was performed using the content analysis method proposed by Bardin (2011). Nineteen learners of the referred course contributed to this research. The obtained and analyzed data indicate that, for this group of students, the evaluation of learning is an important element of the teaching process and if it is held in a fair and inclusive way, it can contribute to the learning process. Hence, it is concluded that the discussions that involve the theme of this research has been contributing to some teachers to incorporate new concepts and perspectives about assessment, but this does not reflect significant changes in the accomplishment of the evaluative practices, since much of it still reproduces non-inclusive and classificatory assessment forms. / Essa pesquisa se prop?s investigar as pr?ticas avaliativas do processo de ensino-aprendizagem no curso de Licenciatura em Educa??o F?sica da UFRRJ. O problema que norteou a reflex?o e a an?lise da tem?tica apresentada envolve as constantes inquieta??es e reflex?es acerca do processo de avalia??o da aprendizagem educacional, com ?nfase na avalia??o da aprendizagem no ensino superior: a doc?ncia como pr?tica de Inclus?o ou Exclus?o?. No decorrer dos anos foram deflagradas diversas discuss?es envolvendo o processo de avalia??o do ensino aprendizagem, tanto no campo educacional, como na ?rea da Educa??o F?sica. Este processo sofreu diversas modifica??es em decorr?ncia das transforma??es estruturais na sociedade, das mudan?as no comportamento humano, dos avan?os cient?ficos e tecnol?gicos, entre outros fatores. Novos significados foram sendo incorporados a este processo, com o intuito de tornar a avalia??o mais significativa para a aprendizagem, tentando desta forma desenraizar-se daquele m?todo de avalia??o tradicional do qual este processo se originou. A metodologia parte de uma pesquisa qualitativa. O m?todo utilizado para a coleta de dados da foi um question?rio semiestruturado composto por dez perguntas, abertas e fechadas. A an?lise dos dados foi realizada com o m?todo de an?lise de conte?do proposto por Bardin (2011). Contribu?ram, como sujeitos da pesquisa, dezenove discentes do referido curso. Os dados obtidos e analisados apontam que, para esse grupo de discentes, a avalia??o da aprendizagem ? um elemento important?ssimo do processo de ensino e que se realizada de forma justa e inclusiva pode contribuir para o processo de aprendizagem. Assim, conclui-se que as discuss?es que envolvem a tem?tica dessa pesquisa tem contribu?do para que parte dos docentes incorporem novos conceitos e perspectivas sobre a avalia??o, mas isso n?o reflete mudan?as expressivas na realiza??o das pr?ticas avaliativas, tendo em vista que grande parte ainda reproduz formas de avalia??o n?o-inclusivas e classificat?rias.

In the search to make the process more cooperative, that is to say, by having students actively participating in the discussion of themes several techniques have been developed. In this paper, we will discuss some fundamental concepts in Physics ? magnitudes and its measurement units, length, ratio and proportion, area and volume ? in the attempt to investigate how students understand these concepts and how some tangible activities done inside the classroom with students of any school year help them to set more advanced and abstracts Physics concepts. Elaborating simple and concrete material brings many possibilities either for students or for teachers. With the handling and experimentation of these materials, students will understand the basic phenomena associated to it, so teachers could rethink their own lessons, in addition to discuss with the students how they need to go through the concrete ?thought? so they can think of the magnitudes in a more abstract way, which we do, in most cases, in Physics teaching. Thereby this paper exposes a wide-ranging discussion about the need and the importance of the concrete to improve students learning in order to enhance classes, stimulate the students and enable them to be able to appropriate the themes that are presented to them in Physics. / Muitos alunos chegam ao Ensino M?dio com uma grande dificuldade de entender os conte?dos b?sicos de F?sica, justamente por n?o terem aprendido de maneira concreta os conceitos b?sicos, como por exemplos as unidades de medidas, as opera??es b?sicas etc. Isto acaba se tornando um dos maiores desafios enfrentados por n?s, professores, nas salas de aula, que buscamos tornar as aulas atrativas e significativas para a aprendizagem dos alunos. Na busca por tornar o processo mais colaborativo, isto ?, fazendo com que os alunos participem da discuss?o dos temas, muitas t?cnicas t?m sido desenvolvidas. Neste trabalho ser?o discutidos alguns conceitos basilares em F?sica? grandezas e suas unidades de medidas, comprimento, raz?o e propor??o, ?rea e volume - na tentativa de investigar como os alunos compreendem esses conceitos e como algumas atividades concretas realizadas em sala de aula, com alunos de qualquer ano escolar, ajudam a formar conceitos mais avan?ados e abstratos da F?sica. Elaborar materiais concretos simples traz muitas possibilidades, tanto para alunos quanto para os professores. Com a manipula??o e experimenta??o desses, os alunos compreender?o os fen?menos b?sicos envolvidos, j? os professores poder?o repensar suas aulas, al?m de discutir como os alunos necessitam passar pelo ?pensamento? concreto para ent?o conseguir pensar nas grandezas de forma mais abstrata, o que fazemos, na maior parte das vezes, no Ensino de F?sica. Deste modo, pretende-se expor uma ampla discuss?o sobre a necessidade e import?ncia do concreto para melhorar a compreens?o dos alunos, com o intuito de melhorar as aulas, estimular os alunos e fazer com que esses sejam capazes de se apropriar dos temas que s?o apresentados a eles na F?sica.
