Abstract

OBJECTIVE

To evaluate the acute effects of maternal and fetal hemodynamic responses in pregnant women submitted to fetal Doppler and an aerobic physical exercise test according to the degree of effort during the activity and the impact on the well-being.

METHODS

Transversal study with low risk pregnant women, obtained by convenience sample with gestational age between 26 to 34 weeks. The participants carry out a progressive exercise test.

RESULTS

After the exercise session, reduced resistance (p=0.02) and pulsatility indices (p=0.01) were identified in the umbilical artery; however, other Doppler parameters analyzed, in addition to cardiotocography and fetal biophysical profile did not achieve significant change. Maternal parameters obtained linear growth with activity, but it was not possible to establish a standard with the Borg scale, and oxygen saturation remained stable.

CONCLUSION

A short submaximal exercise had little effect on placental blood flow after exercise in pregnancies without complications, corroborating that healthy fetus maintains homeostasis even in situations that alter maternal hemodynamics.

OBJETIVO

Avaliar os efeitos agudos de respostas hemodinâmicas maternas e fetais em gestantes submetidas a Doppler fetal e a um teste de exercício físico aeróbio, de acordo com o grau de esforço durante a atividade e o impacto sobre o bem-estar.

MÉTODOS: Estudo transversal desenvolvido com gestantes de baixo risco, por amostra de conveniência com idade gestacional entre 26 e 34 semanas. As participantes realizam um teste de esforço progressivo.

RESULTADOS

Na artéria umbilical, após sessão de exercício físico, identificou-se a redução do índice de resistência (p=0,02) e do índice de pulsatilidade (p=0,01), mas os demais parâmetros Doppler analisados, além da cardiotocografia e do perfil biofísico fetal, não obtiveram alteração significativa. Os parâmetros maternos obtiveram crescimento linear com a atividade, mas não foi possível estabelecer padrão com a escala de Borg, e a saturação de oxigênio se manteve estável.

CONCLUSÃO: O esforço submáximo curto teve pouco efeito sobre o fluxo de sangue da placenta após o exercício em gestações sem complicações, corroborando que o feto hígido mantém a homeostase mesmo em situações que alterem a hemodinâmica materna.

摘要

目的

根据活动期间的努力程度及对幸福感的影响,评估接受胎儿多普勒检查及有氧体育锻炼测试的孕妇的母体和胎儿血流动力学反应的急性效应。

方法

采用横断面研究,对低风险孕妇进行便利抽样,孕周在26至34周之间。参与者进行渐进性运动测试。

结果

运动后,脐动脉阻力指数(p = 0.02)和搏动指数(p = 0.01)降低;然而,除了胎心监护和胎儿生物物理评分外,其他分析的多普勒参数未出现显著变化。母体参数随活动呈线性增长,但无法用Borg量表建立标准,且血氧饱和度保持稳定。

结论

在无并发症的妊娠中,短时间的次最大运动对运动后胎盘血流影响较小,这证实即使在改变母体血流动力学的情况下,健康胎儿仍能维持体内平衡。
