Previous studies have reported that regular practice of a device-guided slow breathing (DGB) exercise decreases resting blood pressure (BP) in hypertensive patients. The performance of DGB is associated with acute decreases in sympathetic vascular tone, and it has been suggested that the decreases in resting BP produced by regular practice of DGB over periods of weeks is due to chronic decreases in sympathetic nervous system activity. However, the kidneys respond to sympathetically-mediated changes in BP by readjusting blood volume levels within a few days. Thus, the mechanism by which DGB could produce long-term BP changes remains to be clarified. Previous research with laboratory animals and human subjects has shown that slow, shallow breathing that increases pCO2 potentiates blood pressure sensitivity to high sodium intake. These findings raise the possibility that deeper breathing during DGB that decreases BP might involve opposite changes in pCO2. The present study tested the hypothesis that performance of DGB acutely decreases a marker of pCO2, end tidal CO2 (PetCO2). Breathing rate, tidal volume, and PetCO2 were monitored before, during, and after a 15 min session of DGB by patients with elevated blood pressure. Blood pressure, heart rate, and heart rate variability (HRV) were also measured under these conditions. A control group was also studied before, during, and after a 15 min session of spontaneous breathing (SB). The DGB group, but not the SB group, showed progressive and substantial increases in tidal volume and low frequency HRV, and decreases in PetCO2 and systolic blood pressure. The PetCO2 effects persisted into the post-task, rest period. The findings are consistent with the hypothesis that habitual changes in breathing patterns of the kind observed during DGB could potentiate an antihypertensive adaptation via effects on pCO2 and its role in cardiovascular homeostasis.

“…Importante ressaltar que o GRF não realizou os exercícios respiratórios para que fosse visualizado de forma independente o efeito do protocolo empregado. Isso porque, segundo a literatura, os exercícios respiratórios podem melhorar a função vascular e diminuir os valores pressóricos 13 . Outro dado relevante é que nenhuma medicação anti-hipertensiva especí-fica foi administrada na população estudada.…”

Exercícios funcionais e neuromusculares são importantes ferramentas em centros de reabilitação, porém são pouco explorados em protocolos hospitalares. objetivo: Verificar se exercícios funcionais e neuromusculares são mais eficazes na redução do tempo de internamento e controle da pressão arterial (PA) dos indivíduos hospitalizados do que a fisioterapia hospitalar de rotina. Métodos: Foram incluídos pacientes hospitalizados por enfermidades não cardiológicas e sem hipertensão arterial sistêmica, sendo estes randomizados para grupo controle (GC), que realizou exercícios respiratórios, exercícios ativo-livres para membros superiores/ inferiores e caminhada no corredor, ou grupo de reabilitação funcional (GRF), submetido a exercícios neuromusculares para membros superiores/inferiores, cicloergômetro e treino de subir/descer degraus. Ambos os grupos receberam intervenção 2x/dia. A PA foi aferida na admissão, durante o internamento e na alta hospitalar. O tratamento estatístico foi realizado adotando-se intervalo de confiança de 95% e nível de significância de 5%. resultados: Avaliados 42 voluntários, dos quais 26 atenderam aos critérios de elegibilidade. Porém, seis foram excluídos, quatro por permanência hospitalar inferior a três dias e dois por não completarem o protocolo de tratamento. A média de idade no GC foi de 72±11 versus 73±8 no GRF. Não houve diferenças estatísticas da PA na admissão. Evidenciou-se redução da PA apenas no GRF durante o internamento (p<0,01), assim como na alta hospitalar (p<0,01). O GC apresentou maior tempo (dias) de internação 7,2±1,8 versus 5,5±1,3 do GRF (p<0,05). Conclusão: Exercícios funcionais e neuromusculares parecem mais eficazes na redução do tempo de internamento e controle da PA dos indivíduos hospitalizados do que a fisioterapia hospitalar de rotina.Palavras-chave: serviço hospitalar de fisioterapia; pressão arterial; terapia por exercício; medicina física e reabilitação; tempo de internação. ABStrACt introduction:Functional and neuromuscular exercises are important tools in rehabilitation centers, however they are little explored in hospital protocols. objective: To determine whether functional and neuromuscular exercises are more effective in reducing hospital stay and controlling blood pressure (BP) of hospitalized individuals than routine hospital physiotherapy. Methods: Hospitalized patients for non-cardiac illnesses and without hypertension were included, which were randomized to the control group (CG), who performed breathing exercises, active-free exercises for upper/lower limbs and walk in the hallway, or to functional rehabilitation group (FRG), which underwent neuromuscular exercises for upper/lower limbs, cycle ergometer and up/down stairs training. Both groups received intervention 2x/day. BP was measured at admission, during hospitalization and at discharge. Statistical analysis was performed by adopting a confidence interval of 95% and a 5% significance level. results: Forty-two volunteers were evaluated, of which 26 met the eligibility criteria.

This study evaluated the effects of the relaxation and breathing training for hypertensive patients on the index, levels and symptoms of stress and blood pressure among hypertensive patients suffering from stress. Nineteen patients from a hypertension and diabetes program in Rio de Janeiro participated in the study that which used, as instruments, Lipp's inventory of stress symptoms for adults, the psychological interview for hypertensive patients, the relaxation and breathing training for hypertensive patients protocol, weekly registration form and blood pressure monitors. The experimental group received the relaxation and breathing training for hypertensive patients in 13 sessions of 60 minutes and had blood pressure monitored before and after each session. The control group had blood pressure monitored weekly. It was observed that the relaxation and breathing training for hypertensive patients reduced the stress index and symptoms in the experimental group in isolation, except when compared to the control group. However, it did not reduce the levels of blood pressure in the experimental group in comparison to the control group. The results report that, besides the relaxation and breathing training for hypertensive patients, other strategies are necessary to control stress and hypertension.
