Objectives: To determine the effect of two resistance training intensities on resting blood pressure and the effect of resistance training on functional capacity in elderly women with systemic arterial hypertension, analyzing these variables before and after eight weeks of intervention. Methods: Patients underwent eight weeks of resistance training, with a frequency of three times per week on alternate days, in the afternoon. The exercises performed were: leg press, bench press, knee extension, lat pull-down, knee flexion, shoulder abduction, standing cable hip abduction and biceps curl. Results: It was found that patients who underwent training with moderate resistance, showed a reduction on resting values of diastolic blood pressure (DBP) p<0.03 and of mean arterial pressure (MAP) p<0.03. Patients who underwent mild resistance training showed reduction in resting values of MAP (p<0.03) and a tendency to decrease in DBP (p<0.06). With regard to functional capacity, the results showed significant increase in the strength of arms and legs, agility and aerobic endurance (p<0.001) and maintaining flexibility (p>0.05). Conclusion: The data indicated that both mild and moderate resistance training, even when started in old age, promoted cardiovascular benefits and also improve the functional capacity of hypertensive older women. / Os resultados dos estudos sobre a intensidade ideal do treinamento resistido para redu??o dos n?veis press?ricos de repouso, assim como, desse tipo de treinamento sobre o aumento da capacidade funcional de idosas hipertensas ainda s?o obscuros, uma vez que as poucas investiga??es realizadas geralmente analisam indiv?duos jovens normotensos, sendo a literatura carente de informa??o precisa em sujeitos idosos hipertensos. Objetivos: Verificar a repercuss?o de duas intensidades de treinamento resistido sobre a press?o arterial de repouso al?m do efeito do treinamento resistido na capacidade funcional de idosas portadoras da HAS (hipertens?o arterial sist?mica) analisando estas vari?veis antes e ap?s oito semanas de interven??o. M?todos: As pacientes realizaram oito semanas de treinamento resistido, com freq??ncia de tr?s vezes por semana em dias alternados, no per?odo vespertino. Os exerc?cios realizados foram respectivamente: leg press, supino reto, extens?o de joelhos puxada frontal, flex?o de joelhos, abdu??o de membros superiores, abdu??o unilateral de quadril e rosca direta com barra. Resultados: Verificou-se que as pacientes que realizaram treinamento com resist?ncia moderada, apresentaram redu??o tanto nos valores de repouso da press?o arterial diast?lica (PAD) p<0,03 como na press?o arterial m?dia (PAM) p<0,03. As pacientes que realizaram treinamento leve apresentaram redu??o nos valores de repouso da PAM (p<0,03) e tend?ncia ? redu??o na PAD (p<0,06). Quanto ? capacidade funcional, os resultados mostraram aumento significativo da for?a de membros superiores e inferiores, agilidade e endurance aer?bica (p<0,001) e manuten??o da flexibilidade (p>0,05). Conclus?o: Os dados mostraram que tanto o treinamento resistido moderado quanto o leve, mesmo quando iniciados na terceira idade, promoveram benef?cios cardiovasculares e tamb?m na capacidade funcional de idosas hipertensas.

The chronic Chagas cardiomyopathy (CCC) has some peculiarities such as arrhythmias and, especially heart failure (HF) and is potentially lethal due to left ventricular dysfunction. How respiratory disorders, patients get progressive loss of functional capacity, which contributes to a poor quality of life related to disease. Measurements of lung volume by the movement of the chest wall surface are an alternative evaluation of lung function and kinematics of complex thoracoabdominal for these patients. OBJECTIVE: evaluate the kinematics of the thoracoabdominal complex through the regional pulmonary volumes and to correlate with functional evaluation of the cardiorrespiratory system in patients with Chagas disease at rest. MATERIALS AND METHODS: a cross-section study with 42 subjects had been divided in 3 groups, 15 composed for patients with CCC, 12 patients with HF of different etiologies and 15 healthful presented control group. An optoelectronic plethysmography (POE), Minnesota questionnaire, six minute walk test, spirometer and manovacuometer was used. RESULTS: It was observed in the 6MWT where group CRL presented greater distance 464,93?44,63m versus Group HF with 399,58? 32,1m (p=0,005) and group CCC 404?68,24m (p=0,015), both the groups presented difference statistics with regard to Group CRL. In the manovacuometer 54,59?19,98; of the group CCC and 42,11?13,52 of group IC found group CRL presented 81,31?15,25 of the predicted versus, presenting in relation to group CRL. In the POE it observed a major contribution in abdominal compartment in patients with IC if compared like CCC and control groups. On the basis of the questionnaire of quality of life of Minessota, verified a low one groups CCC and IC 43,2?15,2 and 44,4?13,1, respectively (p<0,05) when compared with the control group (19,6?17,31). CONCLUSION: it seems that the patients with CCC possess same functional and respiratory characteristics, observed for the POE, 6MWT, manovacuometer and spirometer to the patients of group HF, being able to consider similar interventions for this complementary group as therapeutical of this neglected disease / INTRODU??O: As manifesta??es pulmonares e card?acas da Doen?a de Chagas (DC) afetam entre 20 a 30% dos indiv?duos infectados. A Cardiomiopatia Chag?sica Cr?nica (CCC) possui algumas particularidades tais como arritmias e, principalmente a Insufici?ncia Card?aca (IC), sendo potencialmente letal devido a disfun??o ventricular esquerda. Como altera??es respirat?rias, os pacientes adquirem progressivo preju?zo da capacidade funcional, o que contribui para uma pobre qualidade de vida relacionada ? doen?a. As medidas dos volumes pulmonares atrav?s do movimento da superf?cie caixa tor?cica surgem como alternativa de avalia??o da fun??o pulmonar e da cinem?tica do complexo t?raco-abdominal para estes pacientes. OBJETIVO: analisar a cinem?tica do complexo t?raco-abdominal atrav?s dos volumes pulmonares regionais e correlacionar com avalia??o funcional do sistema cardiorrespirat?rio em pacientes com Doen?a de Chagas durante o repouso. MATERIAIS E M?TODOS: estudo transversal com 42 sujeitos que foram alocados em 3 grupos, sendo 15 composta por pacientes com CCC, 12 pacientes com IC de diferentes etiologias e 15 idosos saud?veis. Foi utilizado um pletism?grafo opto eletr?nico (POE), question?rio de Minessota, teste de caminhada 6 minutos, espirometria e manovacuometria. RESULTADOS: Observou-se no TC6min onde o grupo idosos apresentou maior dist?ncia percorrida 464,93?44,63m vs Grupo IC com 399,58? 32,1m (p=0,005) e grupo CCC 404?68,24m (p=0,015), ambos os grupos apresentam diferen?a estat?stica com rela??o ao Grupo Idosos. Na manovacuometria o grupo idosos apresentou 81,31%?15,25 do predito vs 54,59%?19,98 do grupo CCC e 42,11%?13,52 do grupo IC, apresentando (p<0,05) em rela??o ao grupo Idosos. Na POE observou-se uma maior contribui??o do compartimento abdominal no grupo IC o que n?o aconteceu com os grupos CCC e controle. Com base no question?rio de qualidade de vida de Minessota, verificou-se um baixo escore nos grupos CCC e IC 43,2?15,2 e 44,4?13,1, respectivamente (p<0,05) quando comparados ao grupo controle (19,6?17,31). CONCLUS?O: os dados sugerem que os pacientes com CCC possuem mesmas caracter?sticas funcionais e respirat?rias, observadas pela POE, TC6min, manovacuometria e espirometria aos pacientes do grupo IC, a capacidade funcional apresentou-se diminu?da, podendo considerar interven??es semelhantes para esse grupo como terap?utica complementar dessa doen?a negligenciada

Methods: Eighty-nine volunteers of both genders, healthy and physically active, with a mean age of 22.52 ? 2.6 years and mean BMI 23.86 ? 3.2 kg/m? were randomized into 4 groups: Control Group (CG) made only one Protocol Exercise (PE) without performing the stretching, the Experimental Group 1 (EG1) did stretching before PE; EG2 did the stretching after PE and EG3 did stretching before and after PE. The volunteers were evaluated on the following variables: Range of motion (ROM), soreness, dynamometric variables concentric and eccentric, Neuromuscular Latency Time (NLT) and electromyographic. In the data analysis was assigned a significance level of 5%. Results: ADM and TLNM reported significant reduction in CG, but remained unchanged in GE with p<0,05 and p<0,01, respectively. As for the soreness, no differences between the groups. The electromyographic activity of the BF and ST, in the concentric phase, showed a significant decrease in all groups (p<0,01). However, in the eccentric phase, ST revealed reduction in all groups (p <0.01), except for the CG, while the BF remained unchanged in all groups. The PT showed significant reduction in both conditions (concentric and eccentric) for all groups, with no difference between them (p<0,01). Conclusion: The results of this study do not favor the use of static stretching, even of short duration, before physical activity. However, after exercise or at times unrelated to the sport, he should be given with the aim of avoiding muscle shortening / Objetivo: Avaliar os efeitos agudos do alongamento est?tico, antes e ap?s exerc?cio isocin?tico, nas propriedades neuromusculares e biomec?nicas dos m?sculos B?ceps Femoral (BF) e Semitend?neo (ST). Metodologia: Oitenta e nove volunt?rios de ambos os g?neros, saud?veis e fisicamente ativos, com idade m?dia de 22,52 ? 2,6 anos e IMC m?dio de 23,86 ? 3,2 kg/m2 foram distribu?dos aleatoriamente em um dos 4 grupos: o Grupo Controle (GC) fez apenas um Protocolo de Exerc?cio (PE) sem a realiza??o do alongamento; o Grupo Experimental 1 (GE1) fez alongamento antes do PE; o GE2 fez alongamento ap?s o PE e o GE3 fez alongamento antes e ap?s o PE. Os volunt?rios foram avaliados quanto ?s seguintes vari?veis: Amplitude de Movimento Articular (ADM), sensa??o dolorosa, vari?veis dinamometricas conc?ntricas e exc?ntricas, Tempo de Lat?ncia Neuromuscular (TLNM) e atividade eletromiogr?fica. Na an?lise dos dados foi atribu?do um n?vel de signific?ncia de 5%. Resultados: A ADM e o TLNM apresentaram significativa redu??o no GC, mas permaneceram inalterados nos GE com p<0,05 e p<0,01, respectivamente. Quanto ? sensa??o dolorosa n?o houve diferen?as entre os grupos. A atividade eletromiogr?fica do BF e ST, na fase conc?ntrica, apresentou uma diminui??o significativa em todos os grupos (p<0,01). Por?m, na fase exc?ntrica, o ST revelou redu??o para todos os grupos (p<0,01), exceto para o GC, enquanto o BF permaneceu sem altera??o em todos os grupos. O PT apresentou redu??o significativa nas duas condi??es (conc?ntrica e exc?ntrica) para todos os grupos, sem diferen?a entre eles (p<0,01). Conclus?o: Os resultados encontrados neste estudo n?o favorecem a utiliza??o do alongamento est?tico, mesmo que de curta dura??o, antes da atividade f?sica.

This is a clinical trial, controlled, randomized, blinded, attended by 80 volunteers of both genders, healthy, with ages between 18 to 28 years. Initially the volunteers performed an initial evaluation (EV1) using electromyography in the biceps muscle, associated with assessment in isokinetic dynamometry with 5 concentric contractions (60 ?/s) for elbow flexion. The subjects were randomly allocated into 4 groups: G1 (control, n = 20), G2 (placebo, n = 20), G3 (pre-fatigue laser, n = 20), and G4 (post fatigue laser, n = 20). The muscular fatigue protocol had 30 concentric isokinetic contractions (120 ?/s). We used a 808 nm laser, power of 100 mW, applied at the belly of the biceps muscle. After the speeches the volunteers performed a final evaluation (EV2). Test was applied to two-way ANOVA with post hoc Turkey, with a significance level of 5%. There was no significant difference in electromyographic evaluation. In dynamometric evaluation showed a drop in peak torque, peak torque normalized to body weight (p <0.001) and average power (p <0, 05) between the initial and final evaluations in control. Among the groups there was a significant difference between the control and the other groups in relation to peak torque (p <0.05), peak torque to body weight (p <0.001) and average power (p <0.05). Therefore, the low intensity laser therapy does not alter the immediate neuromuscular performance after fatigue / O objetivo desse estudo foi investigar os efeitos imediatos da laserterapia sobre o desempenho neuromuscular em sujeitos saud?veis, ap?s um protocolo de fadiga muscular. Trata-se de um ensaio cl?nico, controlado, randomizado e cego, no qual participaram 80 volunt?rios de ambos os g?neros, ativos, com faixa et?ria entre 18 ? 28 anos. Inicialmente os volunt?rios realizaram uma avalia??o inicial (AV1), utilizando a eletromiografia do b?ceps braquial, associado ? avalia??o por dinamometria isocin?tica, com 5 contra??es conc?ntricas (60?/s) para flex?o de cotovelo. Os sujeitos foram alocados randomicamente em 4 grupos: o G1 (n=20), controle, G2 (n=20), placebo, o G3 (n=20), laser pr?-fadiga e o G4 (n=20), laser p?s-fadiga. O protocolo de fadiga muscular possu?a incluiu 30 contra??es isocin?ticas conc?ntricas (120?/s). Foi utilizado um laser de 808 nm, pot?ncia de 100 mW, energia total de 20 J, aplicado no ventre do m?sculo b?ceps braquial. Ap?s as interven??es os volunt?rios realizaram uma avalia??o final (AV2). Foi aplicado o teste de Anova two-way, com post-hoc de Turkey, com n?vel de signific?ncia de 5%. N?o existiu diferen?a significativa na avalia??o eletromiogr?fica. Na avalia??o dinamom?trica observou-se uma queda do Pico de Torque, Pico de torque normalizado pelo peso corporal (p<0,001) e Pot?ncia m?dia (p<0,05), entre as avalia??es inicial e final no grupo controle. Observou-se diferen?a significativa entre o controle e os demais grupos, em rela??o ao pico de torque (p<0,05), pico de torque pelo peso corporal (p<0,001) e pot?ncia m?dia (p<0,05). Assim, a laserterapia de baixa intensidade n?o alterou o desempenho neuromuscular ap?s a fadiga nesses sujeitos

Wistar rats were divided in 4 groups: sedentary control (SC), trained control (TC), sedentary diabetic (SD) and trained diabetic (TD). T1D was induced by streptozotocin (45 mg/kg). The training program consisted of 4 weeks running on a treadmill (13 m/min, 60 min/day, 5 days/week). At the end of the experiments, hearts were collected for analysis of morphology and transcriptional profile of LV, by focusing on its remodeling. Deaths were recorded during the 4-week period. We verified high mortality among animals of DS group, whereas it was significantly reduced in DT group. DS group also showed an increase in cross-sectional area of cardiomyocytes and fibrosis. TD group exhibited reduction in measures of cardiac trophism, but with respect to collagen content, it was similar to CS group. Analysis of gene expression related to cardiac remodeling revealed decreased expression of collagen I and III, as well as low expression of MMP-2 in DS group. TD group showed decreased levels of mRNA for MMP-9, and unchanged gene expression of MMP-2 when compared with the CS group. The expression of MMP-2 and TGF-&#61538;1 were increased in CT group. The ratio between gene expression of collagen I and III was increased in the CT group and decreased in diabetic groups. These results establish early changes of the structure and transcriptional profile of LV myocardium. Moreover, they indicate that aerobic exercise training plays specific protection against mechanisms responsible for cardiac damage observed in T1D / Nosso objetivo foi investigar os efeitos de um programa de treinamento aer?bio sobre o remodelamento adverso e precoce do ventr?culo esquerdo (VE), utilizando modelo experimental de curto prazo de diabetes tipo 1 (DM1). Ratos Wistar foram divididos em 4 grupos: controle sedent?rio (CS), controle treinado (CT), diab?tico sedent?rio (DS) e diab?tico treinado (DT). O DM1 foi induzido por estreptozotocina (45 mg/kg). O programa de treinamento consistiu em 4 semanas de corrida em esteira (13 m/min, 60 min/dia, 5 dias/semana). Ao fim dos experimentos, os cora??es foram coletados para analise da morfologia e do perfil transcricional do VE, com foco em seu remodelamento. Os ?bitos foram registrados durante as 4 semanas. Verificamos alta mortalidade entre os animais do grupo DS, enquanto que esta foi significativamente reduzida no grupo DT. O grupo DS apresentou aumento na ?rea de sec??o transversa dos cardiomi?citos e fibrose. O grupo DT exibiu redu??o das medidas de trofismo card?aco, mas com rela??o ao conte?do col?geno, foi similar ao grupo CS. As an?lises de express?o de genes ligados ao remodelamento card?aco revelaram redu??o na express?o dos col?genos I e III, al?m de baixa express?o da MMP-2, no grupo DS. O grupo DT apresentou diminui??o dos n?veis de mRNA para MMP-9, e express?o g?nica de MMP-2 inalterada, se comparado ao grupo CS. As express?es da MMP-2 e do TGF-&#61538;1 foram aumentadas no grupo CT. A raz?o entre express?o g?nica dos col?genos I e III mostrou-se elevada no grupo CT e reduzida nos grupos diab?ticos. Esses resultados estabelecem altera??es precoces da estrutura e do perfil transcricional do VE. Ainda, indicam que o treinamento aer?bio exerce prote??o espec?fica contra mecanismos respons?veis pelo dano card?aco observado no DM1

Nossa an?lise fundamenta-se no m?todo cr?tico-dial?tico, com a utiliza??o da pesquisa bibliogr?fica, documental e de campo, com abordagem de natureza essencialmente qualitativa, tendo como sujeitos de pesquisa 08 (oito) assistentes sociais que atuam diretamente na pol?tica de assist?ncia estudantil nas IFES do Estado, localizadas nas 04 (quatro) mesorregi?es do RN. Para a coleta de dados foram utilizados question?rios de pesquisa, encaminhados por meio eletr?nico ?s participantes contendo quest?es abertas e fechadas, que foram analisadas a partir da t?cnica de an?lise de conte?do. As an?lises realizadas revelaram que a dimens?o educativa do exerc?cio profissional est? presente no cotidiano profissional das participantes de maneira muito t?mida. O impedimento para a realiza??o de atividades educativas pode estar relacionado aos fatores de precariza??o das rela??es de trabalho nas IFES, decorrentes da sobrecarga de trabalho ou da dificuldade de atribuir ? pr?tica profissional o reverso da compet?ncia burocr?tica, determinada pela compet?ncia cr?tica da atua??o profissional. / This work is about the professional practice of social worker in higher education with a view to demarcating the particularity of the educational dimension in student assistance policy carried out in the framework of Federal Institutions of Higher Education (IFES) in Rio Grande do Norte. The seizure and analysis of this object is constituted as the general objective of this dissertation, in order to understand the peculiarity of the educational dimension that sociocupacional space, from the pedagogical-interpretative actions materialized in the context of service to students. Therefore, we mapped and characterized the RN IFES and locate the inclusion of social services in their technical and professional staff, identifying the objective and subjective conditions of work as well as the actions undertaken by social workers with a view to apprehending the pedagogical- actions interpretative that particularize the educational dimension developed in the professional practice of social workers in student assistance. Our analysis is based on the critical-dialectical method, with the use of literature, documentary and field, with essentially qualitative approach, having as research subjects eight (08) social workers who work directly in the student assistance policy in IFES State, located in 04 (four) RN mesoregions. For data collection survey questionnaires were used, forwarded electronically to participants with open and closed questions, which were analyzed from the content analysis technique. The analyzes revealed that the educational dimension of professional practice is present in the daily work of participants in a very shy way. The impediment to the realization of educational activities may be related to factors precariousness of labor relations in IFES, resulting from work overload or difficult to assign to professional practice the reverse of bureaucratic competence, determined by the critical competence of professional practice.

M?todos: Trata-se de um ensaio cl?nico randomizado e duplo-cego composto por 22 mulheres divididas em dois grupos de forma aleat?ria em blocos: grupo placebo (n=11) que foi submetido a um programa de exerc?cios funcionais associado a TLBI placebo; e o grupo laser (n=11) que foi submetido ao mesmo programa de exerc?cios associado a TLBI ativa. O programa de exerc?cio teve dura??o de dois meses e frequ?ncia de tr?s vezes semanais. A TLBI (808nm; 100mW; 4J e 142,85 J/cm2 por ponto) foi aplicada imediatamente ap?s cada sess?o de exerc?cio em diferentes pontos dos m?sculos quadr?ceps (8), isquiotibiais (6) e tr?ceps sural (3), bilateralmente. Todos os indiv?duos foram submetidos a avalia??es pr? e p?s interven??o quanto a: dor (locais, intensidade e limiar), desempenho funcional (equil?brio, testes funcionais), desempenho muscular (flexibilidade e vari?veis isocin?ticas), depress?o e qualidade de vida. A an?lise estat?stica foi realizada por meio do SPSS 20.0 adotando um intervalo de confian?a de 95%. Resultados: Pode-se observar que houve uma redu??o da dor e melhora do desempenho funcional e muscular, da depress?o e qualidade de vida em ambos os grupos (p<0,05), por?m, sem diferen?as significativas entre eles (p>0,05). Conclus?o: O programa de exerc?cio funcional foi eficaz na melhora da dor, desempenho funcional e qualidade de vida de indiv?duos com fibromialgia. No entanto, a TLBI n?o promoveu um incremento nos efeitos positivos proporcionados pelo exerc?cio. / Background: Fibromyalgia is a disease that presents chronic and diffuse musculoskeletal pain associated with fatigue, sleep disturbance, cognitive problems and low levels of physical conditioning. Recent studies have shown good results both with the practice of functional exercises or with the use of low-level laser therapy (LLLT) to reduce the symptoms of this population. However, no evidence was found associating both forms of therapy in the treatment of fibromyalgia. Objective: To investigate the effects of a LLLT associated with an exercise program on pain, functional capacity and quality of life of individuals with fibromyalgia. Methods: It was performed a randomized, double-blind clinical trial with 22 women randomly divided into two blocked groups: placebo group (n = 11) who went through a functional exercise program associated with placebo LLLT and the laser group (n = 11), who underwent the same functional exercise program associated with active TLBI. The exercise program occurred in two months and three times a week. The LLLT (808nm; 100mW; 4J e 142,85 J/cm2 per point) was applied right after each exercise program session in different points of quadriceps (8), hamstrings (6) and sural tr?ceps (3), bilaterally. Both groups were submitted to an evaluation of pain (sites, intensity and threshold), functional capacity (balance, functional tests), muscle performance (flexibility and isokinetic variables), depression and quality of life, before and after the intervention. Statistical analysis was performed using SPSS 20.0 adopting a 95% confidence interval. Results: It was observed that there was a reduction of pain and depression levels and an improvement of functional capacity, muscular performance and quality of life in both groups (p<0.05), but with no significant differences among them (p>0.05). Conclusion: The functional exercise program was effective on pain relief, better functional capacity and quality of life of individuals with fibromyalgia. However, LLLT did not promote an increase on the positive effects caused by the exercise.

O seu tratamento se baseia em alcan?ar e manter um bom controle da doen?a. No entanto, na ?vida real?, o controle sub?timo da asma ? frequente. Nesse sentido, o treinamento muscular inspirat?rio (TMI) pode ser uma boa alternativa para complementar a tradicional terapia medicamentosa. Objetivo: Avaliar a efetividade e seguran?a do TMI em indiv?duos com asma. M?todos: Trata-se de ensaio cl?nico randomizado, duplo-cego. A amostra foi composta por 29 indiv?duos asm?ticos divididos em dois grupos: 14 participantes do grupo com carga leve (C15%) e 15 no grupo de treinamento com carga moderada (C50%). O TMI foi realizado 5 dias por semana, durante 6 semanas, com aparelho POWERbreathe?. As sess?es consistiram de 30 repeti??es duas vezes por dia. Os indiv?duos do C15% treinaram com carga de 15% da press?o inspirat?ria m?xima (PIm?x), enquanto o C50% treinou com 50% da PIm?x. Inicialmente, os participantes foram submetidos a avalia??es da fun??o pulmonar. Em seguida, foram aplicados o Asthma Quality of Life Questionnaire (AQLQ, Question?rio de Qualidade de Vida em Asma) e Asthma Control Questionnaire (ACQ, Question?rio de Controle da Asma). A for?a muscular respirat?ria foi obtida pela PIm?x e pela press?o expirat?ria m?xima (PEm?x). Foram avaliados ainda o n?vel de dispneia antes e ap?s o teste da caminhada de 6 minutos (TC6), atrav?s da escala de Borg CR10, e a capacidade funcional pela dist?ncia percorrida no TC6 (DTC6). Por fim, um di?rio de treinamento foi utilizado para registro de eventos adversos e ades?o as sess?es de TMI. As avalia??es foram realizadas no in?cio do estudo, ap?s 6 semanas de treinamento e seis semanas ap?s a cessa??o do treinamento. Resultados: Ap?s 6 semanas de TMI, a PIm?x aumentou 20,7 cmH2O e 33,1 cmH2O nos grupos C15% e C50%, respectivamente. A PEm?x mostrou um ganho de 10,4 cmH2O no grupo C50% e 8,1 cmH2O no grupo C15%. No AQLQ, foi observada uma prov?vel melhora cl?nica (acima de 0,5) em dois dom?nios (limita??o de atividade e fun??o emocional) no grupo C15% e em todos os dom?nios no grupo C50%. No grupo C50%, houve ainda uma potencial redu??o de 1,13 e 1,42 pontos na escala de Borg CR10 antes e ap?s o TC6, respectivamente. Ao final do TMI, n?o houve diferen?a no controle da asma, DTC6 e fun??o pulmonar para ambos os grupos. Durante o per?odo de treinamento, nenhum volunt?rio foi hospitalizado ou admitido em um servi?o de emerg?ncia, nem houve relato de crise asm?tica devido ao TMI. A ades?o ao TMI n?o foi analisada, uma vez que a grande maioria dos participantes n?o registraram as sess?es realizadas no di?rio de treinamento. Seis semanas ap?s a cessa??o do TMI, apenas 31% dos participantes retornaram para a avalia??o. Assim, n?o foi poss?vel incluir os efeitos da reversibilidade do treinamento em nossos resultados. Conclus?es: Em indiv?duos com asma, o TMI domiciliar com carga leve e moderada mostrou-se seguro e eficaz para aumentar a for?a dos m?sculos respirat?rios e melhorar a qualidade de vida. Al?m disso, o treinamento com carga moderada reduziu o n?vel de dispneia. / Background: Asthma is one of the most prevalent chronic diseases in the world and is considered a serious public health problem. Asthma treatment is based on achieving and maintaining adequate disease control. However, in "real life", suboptimal control of asthma is frequent. In this sense, inspiratory muscle training (IMT) may be a good alternative to complement traditional drug therapy. Objective: To evaluate the effectiveness and safety of the IMT in people with asthma. Methods: This was a double-blind randomized controlled trial. The sample consisted of 29 people with asthma divided into two groups: 14 participants in the low load group (L15%) and 15 in the moderate load group (L50%). IMT was performed 5 days a week for 6 weeks with POWERbreathe? device. The sessions consisted of 30 repetitions twice a day. The L15% group trained with a load of 15% of maximal inspiratory pressure (MIP), while L50% group trained with 50% of MIP. Initially, the participants were submitted to pulmonary function assessments. Then, the Asthma Quality of Life Questionnaire (AQLQ) and Asthma Control Questionnaire (ACQ) were applied. Respiratory muscle strength was obtained by MIP and by maximal expiratory pressure (MEP). The Borg CR10 scale and the distance walked in six-minute walk test (6MWD) were used to assess degree of dyspnea and functional capacity, respectively. Finally, a training diary was used to record adverse events and IMT adherence. Assessments were performed at baseline, after 6 weeks of training and six weeks after cessation of training. Results: After 6 weeks of IMT, MIP increased 20.7 cmH2O and 33.1 cmH2O in the L15% and L50% groups, respectively. MEP showed a gain of 10.4 cmH2O in the L50% group and 8.1 cmH2O in the L15% group. AQLQ showed a probable clinical improvement (above 0.5) in two domains (limitation of activity and emotional function) in the L15% group and in all domains in the L50% group. In the L50% group, there was a potential reduction of 1.13 and 1.42 points on the Borg CR10 scale before and after the 6MWT, respectively. At the end of the IMT, there was no difference in asthma control, 6MWD and pulmonary function for both groups. During the training period, no volunteers were hospitalized or admitted to an emergency department, nor was there an asthmatic crisis due to IMT. Adherence to IMT was not analyzed, since the majority of participants did not record the sessions performed in the training diary. Six weeks after cessation of IMT, only 31% of participants returned for evaluation. Thus, it was not possible to include the effects of training reversibility on our results. Conclusions: In individuals with asthma, home IMT with a low and moderate load proved to be safe and effective in increasing respiratory muscle strength and improving quality of life. In addition, moderate-load training reduced the level of dyspnea.

In this way it is fundamental not only to understand how the different risk and resilience factors to different stressors influence the response to stress, but also to develop strategies that can prevent or minimize the deleterious effects of stress. In this sense, acupuncture is an ancient technique of Traditional Chinese Medicine that has been used in the treatment and prevention of stress-related diseases. The present study proposed the use of two models of stress: one physical (physical exercise) and another psychological (startle model) to verify the reactivity to the stress of athletes horses. In addition, it was also evaluated if horses of different sporting modalities present different psychological stress responses and if acupuncture can alter the responses to physical stress. In the experiment 1, 16 Thoroughbred race horses were submitted to a exercise in the field of high intensity and short duration (12 m / s, 4 min). The RR intervals for analysis of the Heart Rate Variability were acquired through the Polar Equine ? heart rate monitor and blood samples were collected before and immediately after 2h, 4h, 6h, and 24h after exercise. The exercise promoted autonomic alterations in the sympatho-vagal balance since it significantly increased the low frequency component (LF), the heart rate and the LF / HF ratio, and decreased the high frequency component (HF) (p <0.01). There was an increase in hematocrit, plasma proteins, glucose and plasma lactate immediately after exercise (p <0.001). There was an increase (p <0.01) in serum cortisol values after 30 minutes, returning to baseline values after 60 min. However, no significant difference was observed in plasma cytokines IL-1? and IL-6 between moments after exercise and baseline. In experiment 2, horses of the experimental group 1 after exercise were randomly divided into two groups: CTL (C2): Control (without manipulation) and ACUP (C2)): animals submitted to weekly sessions of acupuncture at points VG1, C7, VG20 and B52 for 10 weeks. After the treatment period the animals repeated the same exercise and the same parameters were analyzed. Acupuncture reduced the LF / HF ratio, promoting a faster recovery of the animals, showing no influence on the other parameters analyzed. In the experiment 3, 24 equines were used, from three equestrian modes: Polo (PSI) (n = 9), Dressage (Brazilian Horse Riding) (n = 6) and Endurance (n=6) were subjected to the experimental model of startling through the abrupt opening of an umbrella. The results showed that endurance horses presented a significantly less intense startle-induced autonomic response than Polo and Dressage horses (lower LF / HF ratio at the time of the jump), paradoxically Enduro horses have cortisol levels in response in response to the startle than Polo horses. However, there was no difference between the modalities in the behavioral response after the startle, and Polo horses had significantly higher baseline levels of cortisol than the other modalities and did not change their cortisol levels in response to stress. Thus, we can conclude that 1) the exercise in the field of high intensity and short duration promoted adaptive changes characteristic of stress, being able to be used in studies of reactivity to stress in race horses; 2) acupuncture has a modulating effect on the stress-induced autonomic response in athletic horses, and 3) the equestrian modalities of Dressage, Polo and Endurance present different stress reactivity / O cavalo tem uma predisposi??o natural para o esporte, no entanto, o seu uso em competi??es pode resultar em problemas relacionados ao estresse que prejudicam seu desempenho esportivo e principalmente a sua sa?de. Desta forma ? fundamental n?o apenas entender como os diferentes fatores de risco e de resili?ncia a diferentes estressores influenciam a resposta ao estresse, como tamb?m desenvolver estrat?gias que possam prevenir ou minimizar os efeitos delet?rios do estresse. Neste sentido a acupuntura ? uma t?cnica milenar da Medicina Tradicional Chinesa que tem sido utilizada no tratamento e preven??es de doen?as relacionadas ao estresse. O presente estudo prop?s o uso de dois modelos de estresse: um f?sico (exerc?cio f?sico) e outro psicol?gico (modelo de sobressalto) para verificar a reatividade ao estresse de cavalos atletas. Al?m disso, tamb?m foi avaliado se cavalos de diferentes modalidades esportivas apresentam respostas ao estresse de psicol?gico distintas e se acupuntura pode alterar as respostas ao estresse f?sico. No experimento 1, 16 equinos de corrida da ra?a Puro Sangue Ingl?s foram submetidos ao exerc?cio a campo de alta intensidade e curta dura??o (12 m/s, 4min). Os intervalos RR para an?lise da Variabilidade da Frequencia Card?aca foram adquiridos atrav?s do frequenc?metro card?aco Polar Equine? e as amostras de sangue foram coletadas antes e, imediatamente, 2h, 4h, 6h, e 24h ap?s o exerc?cio. O exerc?cio promoveu altera??es auton?micas no balan?o simpato-vagal uma vez que aumentou significativamente o componente de baixa frequ?ncia (LF), a frequ?ncia card?aca e a raz?o LF/HF e diminuiu o componente de alta frequ?ncia (HF) (p < 0.01). Houve aumento do hemat?crito, das prote?nas plasm?ticas, glicose e lactato plasm?tico imediatamente ap?s o exerc?cio (p < 0.001). Houve aumento (p<0.01) nos valores s?ricos de cortisol ap?s 30 minutos, retornando aos valores basais ap?s 60min. No entanto, n?o foi observado diferen?a significativa nas citocinas plasm?ticas IL-1? e IL-6 entre os momentos ap?s exerc?cio e o momento basal. No experimento 2: os equinos do experimento 1 ap?s o exerc?cio foram aleatoriamente divididos em dois grupos: CTL (C2): Controle (sem manipula??o) e ACUP (C2)ACUP (C2): animais submetidos a sess?es semanais de acupuntura nos pontos VG1, C7, VG20 e B52 durante 10 semanas. Ap?s o per?odo de tratamento os animais repetiram o mesmo exerc?cio e foram analisados os mesmos par?metros. A acupuntura reduziu a raz?o LF/HF, promovendo uma recupera??o mais r?pida dos animais n?o apresentando influ?ncia nos demais par?metros analisados. No experimento 3, foram utilizados 24 equinos, pertencentes a tr?s modalidades equetres: P?lo (ra?a PSI) (n=9), Adestramento (ra?a Brasileiro de Hipismo) (n=6) e Enduro (Puro Sangue ?rabe) (n=9) submetidos ao modelo experimental de sobressalto atrav?s da abertura abrupta de um guarda-chuva. Os resultados mostraram que cavalos de enduro apresentaram resposta auton?mica induzida pelo sobressalto significativamente menos intensa que cavalos de Polo e Adestramento (menor raz?o LF/HF no momento do sobressalto), paradoxalmente cavalos de Enduro possuem n?veis de cortisol em resposta ao sobressalto mais altos que cavalos de Polo. N?o houve diferen?a entre as modalidades na resposta comportamental ap?s o sobressalto, no entanto cavalos de P?lo apresentam n?veis basais de cortisol significativamente mais altos que as demais modalidades e n?o variaram seus n?veis de cortisol em resposta ao estresse. Dessa forma, podemos concluir que 1) o exerc?cio a campo de alta intensidade e curta dura??o promoveu altera??es adaptativas caracter?stica de estresse, podendo ser utilizado em estudos de reatividade ao estresse em cavalos de corrida; 2) a acupuntura tem um efeito modulador da resposta auton?mica induzida pelo estresse em cavalos atletas e 3) as modalidades equestres de Adestramento, Polo e enduro apresentam reatividade ao estresse distintas
