“…40 The timing of prenatal MVPA might be important, though both early and late pregnancy MVPA were linked to better BP or BP control in earlier studies. 8,38,39 The similar findings among different trimesters might reflect the tendency to retain similar MVPA patterns throughout pregnancy as we observed in the MoMHealth cohort. 7 These results regarding favorable effects of MVPA on pregnancy BP are important for 2 main reasons.…”

“…Despite the null effect on adverse pregnancy outcomes, the association with maternal BP is important. Other investigations provided mechanistic detail regarding the BP benefits of exercise in pregnancy and concluded that MVPA was associated with better reflex control of BP in late pregnancy 39 and that energy expenditure in early (<16 wk) pregnancy was related to resting BP in late (36 wk) pregnancy. 40 The timing of prenatal MVPA might be important, though both early and late pregnancy MVPA were linked to better BP or BP control in earlier studies.…”

Background: Moderate to vigorous physical activity (MVPA) and sedentary behavior (SED) are associated with blood pressure (BP) and adverse pregnancy outcomes. The authors investigated associations of prenatal MVPA and SED patterns with BP and with placental malperfusion features. Methods: Women enrolled in this prospective cohort study in the first trimester. MVPA, SED, and BP were measured objectively each trimester. MVPA and SED trajectories were constructed. Placental examinations were conducted in a subset. Associations of trajectories with BPs were assessed with linear regression adjusted for age, race, education, prepregnancy body mass index, and gestational age. Associations with placental malperfusion lesions and weight were adjusted for key covariates. Results: One hundred eleven participants were included; placental exams were available in 50. Participants with high (vs low) SED were younger and more likely to have adverse pregnancy outcomes. High SED (vs low) was associated with higher first trimester systolic (β = 5.3; 95% confidence interval, 0.0 to 10.6) and diastolic (β = 5.0; 95% confidence interval, 1.4 to 8.6) and higher second trimester diastolic (β = 4.9; 95% confidence interval, 1.6 to 8.2) BP. Medium and high MVPA groups were associated with lower postpartum diastolic BP. Trajectories were not associated with placental malperfusion. Conclusions: MVPA and SED patterns were differentially associated with prenatal and postpartum BP. Encouraging favorable levels of both might help women achieve lower BP during and after pregnancy.

“…To the best of our knowledge, this is the first study to investigate associations between movement behaviors taking the 24-h continuum into account with body composition and cardiometabolic health in pregnancy. Moreover, few studies have investigated the associations between individual movement behaviors and body composition and metabolic health using objective methods, and these have mainly focused on outcomes in late pregnancy (e.g., [14][15][16][30][31][32]). Nevertheless, our results are consistent with a study by Loprinzi et al (14) (n = 206), which found that women who engaged in higher levels of LPA and MVPA (objectively measured) had lower diastolic blood pressure and higher HDL cholesterol, respectively.…”

PurposeThe aim of this study was to examine the cross-sectional and longitudinal associations of 24-h movement behaviors (sleep, sedentary behavior (SB), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA)) with body composition and cardiometabolic health in i) early and ii) late pregnancy (gestational weeks 14 and 37).MethodsThis observational study utilized cross-sectional (n = 273) and longitudinal data (n = 242) from the HealthyMoms trial. Time spent in movement behaviors over seven consecutive 24-h periods (ActiGraph wGT3x-BT accelerometer), body composition (Bod Pod), and cardiometabolic health indicators (glucose levels, homeostatic model for insulin resistance (HOMA-IR), systolic and diastolic blood pressure, metabolic syndrome (MetS) score) were measured in early and late pregnancy.ResultsIn early pregnancy, reallocating time to MVPA from LPA, SB, and sleep was associated with lower MetS score (adjusted γ = −0.343, P = 0.002). Correspondingly, reallocating time to LPA from SB and sleep in early pregnancy was associated with lower body weight (adjusted γ = −5.959, P = 0.047) and HOMA-IR (adjusted γ = −0.557, P = 0.031) at the same time point. Furthermore, reallocating time to LPA from SB and sleep in early pregnancy was associated with lower fat mass index (adjusted γ = −0.668, P = 0.028), glucose levels (adjusted γ = −0.315, P = 0.006), HOMA-IR (adjusted γ = −0.779, P = 0.004), and MetS score (adjusted γ = −0.470, P = 0.027) in late pregnancy. The changes in behaviors throughout pregnancy were not associated with body weight, body composition, and MetS score in late pregnancy.ConclusionsOur results demonstrated that increasing LPA or MVPA while reducing SB and sleep was associated with lower weight and more favorable cardiometabolic health in early pregnancy. In contrast, LPA in early pregnancy seems to be a stimulus of enough intensity to improve body composition and cardiometabolic health indicators in late pregnancy.

“…Visontai et al (50) attributed the increase in stiffness to the decrease in cardiovagal BRG that they observed during pregnancy; this was based on a correlation between DC and cardiovagal baroreflex sensitivity (which was decreased in TM2 and TM3 compared with the first trimester or postpartum). We have previously shown that cardiovagal baroreflex is positively correlated with both self-reported physical activity and objectively measured physical activity (i.e., accelerometry) in pregnancy (51), suggesting that physical activity measures in pregnancy may correlate with carotid stiffness measures in these women. We were unable to replicate those data here as we do not have physical activity measures that represent the exercise intervention activity levels in TM3.…”

Purpose: Healthy pregnancy is typically associated with favorable vascular adaptations to both structure and function of the peripheral arteries. Exercise is independently associated with improvements in peripheral vascular health; however, the impact of exercise on prenatal adaptations is unclear. Therefore, we hypothesized that a structured aerobic exercise intervention between the second and third trimesters (TM2 and TM3, respectively) of pregnancy would augment the already-positive changes in vascular outcomes. Methods: We recruited 59 inactive pregnant women (<20 wk of gestation) and randomized them into control (standard care; n = 28) or exercise (moderate-intensity aerobic exercise, 3-4 d•wk −1 , 25-40 min, 14 ± 1 wk; n = 31) conditions. Before and after the intervention, all women completed the comprehensive peripheral vascular assessment, which included blood markers of vascular health, carotid distensibility metrics, measures of arterial stiffness (pulse wave velocity), and [superficial] femoral artery reactivity during cold pressor test. Results: Carotid artery diameter increased from 6.5 to 6.9 mm (P < 0.001), and strain (%) decreased from 9.9% to 8.4% (P < 0.001). Carotid artery blood flow, compliance and distensibility coefficients, stiffness (β), distensibility (1/β), and elastic modulus were not different across gestation. Pulse wave velocity was not different across gestation. Superficial femoral artery diameter was increased from 5.4 to 5.6 mm (P = 0.004), whereas blood flow, conductance, and resistance at rest and during the cold pressor test were not different across gestation. None of our measures of vascular health were impacted by exercise. Conclusions: We did not observe an impact of aerobic exercise on altering the changes across pregnancy in blood vessel health. However, the present study was conducted in women who were overall at low risk for developing gestational hypertension and should be interpreted with caution. Future work in high-risk women is needed.
