“…The strengths of the present study were the prospective approach, use of validated methods and the number of participants who performed the cycle ergometer test in early pregnancy. An additional cycle ergometer test during pregnancy might have added to a small proportion since the difference between the oxygen uptake in early pregnancy and postpartum was small [ 2 ]. Use of a direct method of oxygen uptake would have further increased the accuracy of the physical fitness assessment but this would have been difficult to realise.…”

“…Women who exercise regularly in the non-pregnant state frequently continue to do so during pregnancy [ 1 ], while the proportion of women who exercise declines as pregnancy progresses [ 2 ]. It is recommended that women perform regular exercise during pregnancy [ 3 ], although the impact of physical fitness on duration of gestation or miscarriage is inconsistent.…”

“…assessed in early pregnancy as a measure of physical fitness, in addition to well established, validated assay for serum relaxin analyses, and accurate information about the timing and circumstances of miscarriage and delivery. Estimated absolute peak oxygen uptake is suggested to be an adequate method to be used also in pregnancy as a reliable indicator of physical fitness [ 2 , 22 – 24 ]. The objective of the study was to analyse the impact of physical fitness and relaxin on duration of gestation of the general population.…”

BackgroundWomen are recommended to perform regular exercise during pregnancy but the impact of physical fitness on duration of gestation and miscarriage is inconsistent. In addition, a dose-response relation between the amount of weekly exercise and increased risk of miscarriage in early pregnancy has been observed. Previous studies have mostly used an epidemiologic method. Larger studies using careful measurement of physical fitness are needed. Besides physical fitness, maternal circulating concentrations of the hormone relaxin have been associated with decreased duration of gestation.MethodsA prospective cohort including 20 women with miscarriage and 460 women with spontaneous onset of labour, recruited from maternal health care centres in central Sweden, were examined in early pregnancy regarding estimated absolute peak oxygen uptake (peak, est.) by cycle ergometer test, and maternal circulating serum relaxin concentrations.ResultsWomen with miscarriage displayed the highest level of absolute peak, est. (2.61 l/min) and the lowest serum relaxin concentrations (640 ng/l). Among women with spontaneous onset of labour, the mean absolute peak, est. increased successively from the lowest estimated oxygen uptake of 2.31 l/min among those with preterm birth (n = 28), to an oxygen uptake of 2.49 l/min among women with postterm birth (n = 31). An opposite trend was shown regarding serum relaxin concentrations from women with miscarriage to those with postterm birth. Serum relaxin concentrations, but not absolute peak, est. was significantly and independently associated with duration of gestation in women with miscarriages, and absolute peak, est., age and multiple pregnancy were independently associated with duration of gestation in women with spontaneous onset of labour.ConclusionsPhysical fitness appears to be a protective factor of established pregnancies and not significantly involved in the risk of early miscarriage. Additional studies are needed to more clearly define the role of relaxin in miscarriage.

Bu çalışmada gebe kadınların fiziksel aktivite düzeyleri ve yaşam kalitelerinin incelenmesi amaçlanmıştır. Gereç ve Yöntemler: Kesitsel olarak planlanan bu çalışma, Manisa Celal Bayar Üniversitesi Hafsa Sultan Hastanesi Kadın Hastalıkları ve Doğum Kliniği Gebe Polikliniği'ne başvuran ve son trimesterinde olan 190 gebe ile 1 Ocak-31 Aralık 2018 tarihleri arasında gerçekleştirilmiştir. Araştırma verilerinin toplanmasında gebelerin tanıtıcı özellikleri soru formu, ''Gebelik Fiziksel Aktivite Anketi (GFAA)" ve "SF-36 Yaşam Kalitesi Ölçeği (SF-36)" kullanılmıştır. Bulgular: Gebelerin fiziksel aktivite toplam puan ortancası 110,7 metabolik eşdeğer (MET)-saat/hafta (min=23,7 maks=372,4) bulunmuştur. Kadınlar en çok ev işi/bakım (ortanca: 50,8 MET-saat/hafta) işleri olmak üzere hafif şiddette aktiviteler yaptıklarını (ortanca: 53,13 MET-saat/hafta) ifade etmişlerdir. GFAA toplam puanı ile SF-36 yaşam kalitesi ölçeği fiziksel fonksiyon (p=0,03), emosyonel rol güçlüğü (p=0,005) ve mental sağlık puanı (p=0,046) arasında pozitif yönde istatistiksel olarak anlamlı bir ilişki saptanmıştır. Sonuç: Bu çalışmanın sonuçlarına göre, fiziksel aktivitenin yaşam kalitesini olumlu etkilediği bulunmuş olup sağlıklı kadınların gebelikleri sırasında fiziksel olarak aktif olmalarına yardımcı olacak girişimlerin planlanmasına gereksinim olduğu belirlenmiştir.

“…Among the studies that used %VO 2max , there were different percentages such as 40%[54], 50% [53,59], 60%[52,54], or 70%[178]. Among the studies that used absolute HR as a test termination criterion, the HR for finalizing the tests were set either at 125[86], 150[30,56,66,87], 155 [122], 160[89], or 170[77,78,82,83] beats per minute. Some studies even used the rate perceived exertion as complementary criteria[50,71,78] or peak aerobic power[67].…”

Background: Physical fitness (PF) is a powerful marker of health throughout the lifespan. In pregnant women, higher PF is associated with better maternal and fetal health, better delivery outcomes and earlier postpartum recovery. The assessment of PF during pregnancy requires special considerations to preserve fetal and maternal health; thus, providing a compilation of the most frequently used fitness tests, and assessing their validity, reliability, and association with maternal and neonatal health-related outcomes is of scientific and clinical interest. Objectives: To systematically review studies evaluating one or more components of PF in pregnant women, to answer two research questions: 1) What fitness tests have been previously employed in pregnant women? and 2) What is the validity and reliability of these tests and their relationship with health-related outcomes? Data Sources: PubMed and Web of Science. Methods: Two independent reviewers systematically examined the articles in each database. The information from the included articles was summarized by a single researcher. Results: A total of 149 articles containing a sum of 191 fitness tests were included. Among the 191 fitness tests, 99 (i.e.,52%) assessed cardiorespiratory fitness through 75 different protocols, 28 (15%) assessed muscular fitness through 16 different protocols, 14 (7%) assessed flexibility through 13 different protocols, 45 (24%) assessed balance through 40 different protocols, 2 assessed speed with the same protocol and 3 were multidimensional tests using one protocol. A total of 19 articles with 23 tests (13%) assessed either validity (n=4), reliability (n=6), or the relationship of PF with health-related outcomes (n=16). Conclusion: PF during pregnancy has been assessed through a wide variety of protocols, mostly lacking validity and reliability data.

Moderate impact of full‐term pregnancy on estimated peak oxygen uptake, physical activity and perceived health

Abstract: Pregnancy had a moderate influence on physical fitness and perceived health half a year postpartum despite less regular physical activity during pregnancy. VO(2 peak, est.) in early pregnancy was positively correlated to perceived physical health.
