Key result
Aerobic exercise combined with breathing exercises significantly improved blood oxygenation in pregnant women compared to breathing exercises alone (post-treatment mean difference 2.49, p=0.020).
Why the study?
Pregnancy causes physiological changes affecting oxygenation, but the blood oxygenation response to aerobic exercise combined with breathing exercises in pregnant women was unknown.
Does aerobic exercise combined with breathing exercises improve oxygen saturation in pregnant women?
RCT (n=40)
Simple randomization by sealed envelope

Does aerobic exercise combined with breathing exercises improve oxygen saturation in pregnant women?
Aerobic exercise combined with breathing exercises significantly improves blood oxygen saturation in pregnant women during their third trimester.
Combined aerobic plus breathing exercises improves third-trimester SaO2 more than breathing alone; extends RCT evidence supporting moderate exercise in uncomplicated pregnancy.
Background There are many physiological changes occur during pregnancy that affect oxygenation of the pregnant women. It was considered that aerobic and breathing exercises are safe for the mother and the fetus especially moderate intensity exercise during pregnancy. Objective This study was designed to investigate the blood oxygenation response to aerobic exercise combined with breathing exercises in pregnant women. Methodology Forty pregnant women were selected from obstetrics and gynecology outpatient clinic at Kasr El Einy Hospital, Egypt, confidentiality was assured. They were ranged from 25 to 30 years old, with body mass index (BMI) less than 30 kg/m2and at the beginning of 3rdtrimester, this study was conducted from September 2019 to April 2020. They were assigned into two groups: group A performed aerobic exercise in a form of walking for 20 min. On the treadmill at 60–75% of the maximum heart rate (MHR) of each woman, three times per week in addition to deep breathing exercises in form of diaphragmatic and lateral costal breathing; group B who performed deep breathing exercises only in form of diaphragmatic and lateral costal breathing. The program continued for three months, three times per week. The oxygen saturation (SaO2) was measured twice time, firstly, at the beginning of 3rdtrimester of pregnancy then after three months of treatment program. Results The results of this study revealed a statistically significant difference in the oxygen saturation in group A than in group B. Conclusion It could be concluded that there was significant statistical effect of aerobic exercise combined with breathing exercises on blood oxygenation in pregnant women. It improved the oxygen saturation in pregnant women.

Elsisi et al. (2022) conducted an RCT in Pregnancy (n=40). Aerobic exercise combined with breathing exercises vs. Deep breathing exercises only was evaluated on Oxygen saturation (SaO2) post-treatment (MD 2.49, p=0.020). Aerobic exercise combined with breathing exercises significantly improved blood oxygenation in pregnant women compared to breathing exercises alone (post-treatment mean difference 2.49, p=0.020).
