[en] Introduction. Childbirth is a physiological, dinamic and continous process, influenced by multiple and interconnected factors, which include physical, mental and emotional factors. Yoga, being a practice that includes body and mind, can offer a global approach to these needs during pregnancy. Objective. To compare the effectiveness of a program that includes practicing prenatal yoga together with the common prenatal education, in comparison to isolated prenatal education, in regards to the obstetric and perinatal results in low-risk pregnant women. Methodology. Observational and prospective study of cohorts to be carried between September 2020 and December 2021. A comparison will be made between obstetric results for pregnant women with low obstetric risk in the common prenatal education group at the clinic, which includes practical and theoretical information meetings with relevant information for this stage; and the results of the group that, additionally to these meetings, also goes to the yoga activity for at least eight sessions. The sample size will be n=45 pregnant women per group. From each women, there will a gathering of sociodemographic data, body mass inde, obstetric background and practices of physical exercise before pregnancy, as well as obstetric, maternal and neonatal results. There'll be a comparison of obstetric and perinatal results between both groups, with a bivariate and multivariate analysis through regression models. Limits: the observational nature of the study makes it susceptible of potencial selection bias and confusion. Methods of multivariate analysis will be applied to adjust potential confusion factors that may explain the differences between both study groups. Ethical aspects: the study will require the informated consent of the participants, after the approval of the pertinent ethical committee.

[gl] Introdución. O parto é un proceso fisiolóxico continuo, dinámico e influído por múltiples factores interrelacionados, incluídos factores físicos, mentais e emocionais O ioga, sendo unha práctica que abarca corpo e mente, pode ofrecer un enfoque global das necesidades durante o embarazo. Obxectivo. Comparar a eficacia dun programa que inclúe a práctica do ioga prenatal xunto coa educación materna prenatal habitual, en comparación coa educación materna prenatal illada, en termos de resultados obstétricos e perinatales en mulleres embarazadas de baixo risco. Metodoloxía. Estudo observacional de cohorte prospectivo que se realizará entre setembro de 2020 e decembro de 2021. Os resultados obstétricos compararanse en mulleres embarazadas con baixo risco obstétrico no grupo habitual de educación materna prenatal nun centro de saúde, que inclúe sesións informativas teórico-prácticas de temas de interese durante esta etapa, e os resultados do grupo de mulleres embarazadas que asisten regularmente á educación materna prenatal e tamén á actividade de ioga durante polo menos oito sesións. Incluirase un tamaño de mostra de n=45 mulleres embarazadas por grupo. Recolleranse datos sociodemográficos, índice de masa corporal, historia obstétrica e práctica do exercicio físico antes do embarazo, e resultados obstétricos, maternos e neonatais de cada muller incluída. Compararanse os resultados obstétricos e perinatales entre ambos grupos, realizando unha análise bivariante e multivariante usando modelos de regresión. Limitacións: a natureza observacional do estudo faino susceptible a posibles sesgos de selección e confusión. Utilizaranse técnicas de análise multivariante para axustar por posibles factores de confusión que poidan explicar as diferenzas entre os grupos de estudo. Aspectos éticos: o estudo requirirá o consentimento informado das participantes, coa aprobación previa do comité de ética da investigación pertinente.
