Overall, the literature indicates that participation in
sports and exercise is lower among pregnant women than
non-pregnant women [7, 10–15], but little information is
available on factors associated with continuing exercise
during pregnancy. Only a few studies have compared levels
of sports and exercise before pregnancy with sports and
exercise levels during pregnancy, and identified the determinants of continuing (or stopping) these activities during
pregnancy [13–15]. High BMI has been associated with
both increased [14, 15] and decreased level of sports and
exercise during pregnancy [13], compared to pre-pregnancy levels. Other factors might influence the level of
physical activity during pregnancy. For instance, women
who perceive physical activity during pregnancy as risky to
maternal or fetal health would have a higher propensity to
discontinue exercise activity [16]. Also, early pregnancy
symptoms, such as nausea and fatigue, might be expected
to negatively impact physical activity, although this is not
always the case [7]. Moreover, other aspects of physical
activity, such as household and care-giving activity have
received little attention [17]. More research is needed to
quantify and understand the reasons for changes in physical
activity levels during pregnancy, compared to pre-pregnancy, among healthy pregnant women, particularly with respect to modifiable factors.

Secara keseluruhan, literatur menunjukkan bahwa partisipasi dalamolah raga dan latihan yang lebih rendah antara para wanita hamil daripadaBebas-hamil [7, 10-15], tetapi sedikit informasitersedia pada faktor-faktor yang berhubungan dengan melanjutkan latihanselama kehamilan. Hanya beberapa studi telah membandingkan tingkatolahraga dan latihan sebelum kehamilan dengan olahraga danlatihan tingkat selama kehamilan, dan identified faktor penentu melanjutkan (atau menghentikan) kegiatan selamakehamilan [13 – 15]. BMI tinggi telah dikaitkan dengankeduanya meningkat [14, 15] dan penurunan tingkat olahraga danlatihan selama kehamilan [13], dibandingkan dengan tingkat pra-kehamilan. Faktor-faktor lain mungkin influence tingkataktivitas fisik selama kehamilan. Misalnya, wanitayang memandang aktivitas fisik selama kehamilan sebagai berisiko untukkesehatan ibu atau janin akan memiliki kecenderungan tinggi untukmenghentikan kegiatan olahraga [16]. Juga, awal kehamilangejala, seperti mual dan kelelahan, dapat diharapkanberdampak negatif terhadap aktivitas fisik, meskipun hal ini tidakselalu kasus [7]. Selain itu, aspek-aspek lain dari fisikaktivitas, seperti rumah tangga dan perawatan-memberikan memilikimenerima sedikit perhatian [17]. Penelitian lebih lanjut diperlukan untukmengukur dan memahami alasan-alasan untuk perubahan fisiktingkat aktivitas selama kehamilan, dibandingkan dengan pra-kehamilan, antara para wanita hamil yang sehat, khususnya sehubungan dengan faktor-faktor modifiable.
