Resumo: | Blood pressure control occurs through the interaction between the autonomic nervous system and substances secreted by different cell types, including endothelial cells, causing changes in any of these mechanisms, leading to the development of arterial hypertension. The practice of physical exercises is shown as a non-pharmacological treatment capable of significantly reducing both systolic and diastolic blood pressure, attenuating blood pressure reactivity and increasing the bioavailability of nitric oxide. The objective of the present study was to observe blood pressure, heart rate and vasoactive (nitric oxide) response after an interval aerobic exercise session in hypertensive women. Two protocols were used: one exercise interval (sequence alternating 30 sec/ 90% and 90 sec/ 60% maximal aerobic velocity) and one control session (without exercise). As a result, it was observed that the pressure and heart rate behavior in the post-exercise were similar to the control session, and no attenuation of pressure reactivity after stress test (CPT) was observed when systolic blood pressure was observed in relation to rest: CPT: 160.9 ± 32.27 mmHg x Rest: 122.4 ± 18.58 mmHg and after 60 minutes recovery: CPT: 160.9 ± 32.27 mmHg x 60 min: 121.4 ± 13.87 mmHg. As well as were not observed in relation to the diastolic blood pressure (CPT 99.3 ± 16.19 mmHg x Rest 75.4 ± 15.17 mmHg, moment immediately after exercise: 82.5 ± 9.42 mmHg, and after 60 Min of recovery: 76.3 ± 13.18 mmHg. Regarding the heart rate, no reactivity was noted in the post-exercise period, showing elevation, only when the moment immediately after exercise was observed. Similarly, no differences were observed between the pre and post values related to the bioavailability of nitric oxide, in both protocols. It is concluded that, in the intensity and volume evaluated, physical exercise is not able to attenuate vascular reactivity, nor does it influence nitric oxide concentrations. |

A prática de exercícios físicos se mostra como um tratamento não-farmacológico capaz de reduzir significativamente tanto a pressão arterial sistólica como a diastólica, atenuar a reatividade pressórica e aumentar a biodisponibilidade de óxido nítrico. O objetivo do presente estudo foi observar a resposta pressórica, da frequência cardíaca e de substância vasoativa (óxido nítrico) após uma sessão de exercício aeróbio intervalado em mulheres hipertensas. Para tanto foram realizados dois protocolos, sendo um de exercício intervalado (sequência alternando 30 seg/ 90% e 90 seg/ 60% da velocidade aeróbia máxima) e uma sessão controle (sem exercício). Como resultado, observou-se que o comportamento pressórico e da frequência cardíaca no pós-exercício mostraram-se semelhantes à sessão controle, não sendo evidenciada atenuação da reatividade pressórica pós teste de estresse (CPT) quando observadas a pressão arterial sistólica com relação ao repouso: CPT:160,9 ± 32,27 mmHg x Repouso: 122,4 ± 18,58 mmHg e após 60 minutos de recuperação: CPT:160,9 ± 32,27 mmHg x 60 min: 121,4 ± 13,87 mmHg. Bem como não foram observadas em relação à pressão arterial diastólica (CPT 99,3 ± 16,19 mmHg x Repouso 75,4± 15,17 mmHg; momento imediatamente após o exercício: 82,5± 9,42 mmHg; e, após 60 min de recuperação: 76,3± 13,18 mmHg. Com relação à frequência cardíaca, não foi apontada reatividade no pós exercício, tendo apresentado elevação, apenas, quando observado o momento imediatamente após o exercício. De igual modo, não foram observadas diferenças entre os valores pré e pós relacionados à biodisponibilidade do óxido nítrico, em ambos os protocolos. Conclui-se que, na intensidade e volume avaliados, o exercício físico não é capaz de atenuar a reatividade vascular, assim como não influencia nas concentrações de óxido nítrico.São Cristóvão, SEporHipertensão arterialReatividade pressóricaReatividade vascularÓxido nítricoExercício físicoExercício intervaladoHypertensionPressure reactivityVascular reactivityNitric oxidePhysical exerciseInterval exerciseCIENCIAS DA SAUDE::EDUCACAO FISICAEfeito do exercício intervalado na reatividade pressórica e biodisponibilidade do óxido nítricoinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisPós-Graduação em Educação FísicaUniversidade Federal de Sergipereponame:Repositório Institucional da UFSinstname:Universidade Federal de Sergipe (UFS)instacron:UFSinfo:eu-repo/semantics/openAccessTEXTMARCELA_ESTEVAO_SANTOS.pdf.txtMARCELA_ESTEVAO_SANTOS.pdf.txtExtracted texttext/plain115810https://ri.ufs.br/jspui/bitstream/riufs/8662/3/MARCELA_ESTEVAO_SANTOS.pdf.txt945d2224c38b39b0c37f2b0606793fa2MD53THUMBNAILMARCELA_ESTEVAO_SANTOS.pdf.jpgMARCELA_ESTEVAO_SANTOS.pdf.jpgGenerated Thumbnailimage/jpeg1326https://ri.ufs.br/jspui/bitstream/riufs/8662/4/MARCELA_ESTEVAO_SANTOS.pdf.jpg9718bc1c1719d0f9e73f56d13492d0aeMD54ORIGINALMARCELA_ESTEVAO_SANTOS.pdfMARCELA_ESTEVAO_SANTOS.pdfapplication/pdf881691https://ri.ufs.br/jspui/bitstream/riufs/8662/2/MARCELA_ESTEVAO_SANTOS.pdfb30ea1dfa11b0c652cdf9abaccbff658MD52LICENSElicense.txtlicense.txttext/plain; charset=utf-81475https://ri.ufs.br/jspui/bitstream/riufs/8662/1/license.txt098cbbf65c2c15e1fb2e49c5d306a44cMD51riufs/86622018-08-03 20:02:33.081oai:ufs.br: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Repositório InstitucionalPUBhttps://ri.ufs.br/oai/requestrepositorio@academico.ufs.bropendoar:2018-08-03T23:02:33Repositório Institucional da UFS - Universidade Federal de Sergipe (UFS)false |
