ABSTRACT

Safe and measurable physical activity plays a crucial role in maintaining
maternal cardiovascular health, blood circulation, and oxygen stability
during pregnancy. One natural form of light physical activity routinely
performed by Muslim women is salat (Islamic prayer), which involves a
series of movements such as standing, bowing, prostrating, and sitting.
Each position exerts distinct physiological effects on the cardiovascular and
respiratory systems. This study aims to evaluate the physiological changes
experienced by pregnant women during salat movements using a
smartwatch and to analyze the device’s effectiveness as a digital health
monitoring tool. This research employed a quasi-experimental method
with a one-group pretest-posttest design. The study population consisted of
second-trimester pregnant women residing in East Jakarta. A total of 30
participants were selected through purposive sampling based on normal
health conditions. Physiological parameters—heart rate, blood oxygen
saturation (SpO₂), and activity level—were recorded in real time using a
smartwatch equipped with Photoplethysmography (PPG) and
accelerometer sensors. The results revealed significant yet physiologically
normal changes during salat performance. The average heart rate
increased from 84.6 bpm while standing to 92.5 bpm during prostration,
while SpO₂ remained stable within the 97–98% range. Homogeneity tests
indicated significance values above 0.05, showing uniform data distribution.
The paired sample t-test revealed statistically significant differences
between postures (p < 0.05), with the most pronounced change observed
between standing and prostration (p = 0.000). The N-Gain value of 0.46
indicated a moderate improvement in physiological efficiency. These
findings demonstrate that salat provides a mild physiological stimulus that
is safe and beneficial for pregnant women. The movements enhance blood
circulation, improve cardiovascular efficiency, and maintain stable
oxygenation levels without causing physical strain. The smartwatch proved
to be an effective, non-invasive, and accurate monitoring tool for tracking
physiological responses in real time. Therefore, integrating wearable
technology into religious physical activities such as salat holds potential for
supporting maternal health monitoring in a practical and spiritually
meaningful way.
