Resumo Introdução: O metaborreflexo, ativado pelo acúmulo de metabólitos durante o exercício, ocasiona vasoconstrição periférica, resultando em elevação da pressão arterial. Indivíduos obesos apresentam redução da endurance muscular inspiratória, sugerindo um acúmulo precoce de metabólitos e, consequentemente, alterações no metaborreflexo inspiratório. Objetivo: Comparar as respostas hemodinâmicas mediadas pelo metaborreflexo inspiratório em indivíduos obesos e em eutróficos. Método: Participaram do estudo vinte indivíduos obesos (31 ± 6 anos, dez homens, 37,5 ± 4,7 kg/m 2 ) e vinte eutróficos (29 ± 8 anos, dez homens, 23,2 ± 1,5 kg/m 2 ) submetidos a avaliação da força muscular respiratória através de manovacuometria. O metaborreflexo inspiratório foi induzido através de exercício resistido a 60% da pressão inspiratória máxima mantido até a exaustão. O protocolo controle consistiu na respiração sem resistência inspiratória (zero cmH 2 O) mantida durante 30 minutos. A pressão arterial e a frequência cardíaca foram mensuradas ao longo dos protocolos, realizados em dias distintos e em ordem randomizada. Resultados: O protocolo de indução do metaborreflexo inspiratório induziu aumento das pressões arteriais sistólica, diastólica e média, bem como da frequência cardíaca semelhante em indivíduos obesos e eutróficos. Conforme esperado, no protocolo controle as variáveis hemodinâmicas permaneceram inalteradas. Conclusão: A força muscular inspiratória não variou (p = 0,814) entre indivíduos obesos e eutróficos. Este estudo sugere que indivíduos obesos apresentam respostas hemodinâmicas, induzidas pelo metaborreflexo inspiratório, semelhantes aos indivíduos eutróficos.
Pregnancy can be defined as a period of approximately 40 weeks, in which physiological and mechanic adaptations occur, along with strong psychological modifications. Being a moment of vulnerability, it can be negatively influenced by factors such as urinary incontinence (UI), high-risk pregnancy or even a negative body image. Thus, the aim of this study was to compare body image and the occurrence of urinary incontinence in high-risk and usual risk pregnant women. An observational study with a quantitative and cross-sectional approach was conducted to evaluate the occurrence of urinary incontinence and body image of pregnant women. The sample was divided into two groups: high-risk (n=34) and usual risk (n=31) pregnant women. For the data collection, an identification file was applied, collecting data such as obstetric history, followed by the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF), and the Body Image Measurement Scale (BIMS). It was observed that both groups were dissatisfied with body image, and urinary incontinence occurrence was moderately above to what is found in literature. No relationship between urinary incontinence and body satisfaction was observed in either group. There was no relationship between urinary incontinence and body image. The pregnant women from both groups presented dissatisfaction regarding body image, and the occurrence of urinary incontinence was slightly higher than that observed in literature (50% of occurrence according to national estimates, especially during pregnancy and puerperium).
