“…In this study the orally measured temperature decreased or remained unaffected immediately after exercise. The data on this issue are somewhat conflicting; in some previous studies body temperature did not increase during submaximal exercise and none of the pregnant women even approached a harmful body temperature [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] in pregnant women during aerobic exercise and resistance exercise. There were significant differences between the types of exercise after 15 and 30 min of exercise, p = 0.02 and p = 0.001, respectively.…”

“…Previous research on maternal hemodynamic response [HR, systolic and diastolic blood pressure (BP)] to a single exercise session is sparse. Amorim et al (9) concluded that maternal BP levels were slightly increased during aerobic exercise, followed by a substantial hypotensive effect hours after the exercise session. Recently, Bgeginski et al (10) showed that BP response to resistance exercise is unaffected by pregnancy and this has been demonstrated to remain within safe margins during exercise.…”

“…Data on maternal and fetal hemodynamic responses regarding maternal heart rate (HR), fetal heart rate (FHR), and maternal systolic and diastolic blood pressure is also scarce, and conflicting, and almost non‐existent for women affected by GDM. Previous research has shown that maternal blood pressure levels slightly increased during aerobic and resistance exercise, but remained within safe limits . It is also suggested that prolonged exercise lasting in excess of 45 minutes can lead to hypoglycemia with previous trials confirming a decline in blood glucose levels in women with GDM after exercise .…”

Research on the acute responses to exercise in pregnancy is scarce, especially for women affected by gestational diabetes mellitus (GDM). The aim of this study was to investigate responses to a single bout of exercise performed multiple times throughout the pregnancy in women diagnosed with GDM. Data from 18 pregnant women (aged: 32.8 ± 3.8) diagnosed with GDM, treated with diet only, were analyzed. Participants' pre-pregnancy body mass index was 24.4 ± 4.9 kg/m , 50% of them were nulliparous, and 50% of the sample regularly exercised before the pregnancy. The exercise intervention consisted of an individual structured aerobic and resistance exercise program performed twice per week from the time of diagnosis until at least the 36th week of pregnancy. The exercise program included 20 minutes of aerobic exercise, 20-25 minutes of resistance exercise, and 10 minutes of cool down. Maternal heart rate, systolic and diastolic blood pressure, temperature and fetal heart rate were measured at every exercise session, along with blood glucose on 3 occasions. In total, 365 exercise sessions were analyzed (85 in the second trimester and 280 in the third trimester), on average 20.3 ± 7.7 per participant. Heart rate and fetal heart rate were elevated during both the aerobic and resistance parts of the exercise session (P < .01) in comparison with the baseline while systolic and diastolic blood pressure did not change in the total sample. There was a slight elevation in tympanic membrane temperature during the aerobic part of the session (P < .01). All parameters returned to baseline levels by the end of the session. Glucose levels dropped from the baseline, from 4.7 ± 0.6 to 3.9 ± 0.4 mmol/L (P < .01). There were no differences in responses to exercise between the second and third trimesters, nor between pre-pregnancy exercisers and non-exercisers. The combination of aerobic and resistance exercise for women diagnosed with GDM does not have harmful short-term effects if performed according to guidelines. Likewise, exercise can be considered useful for controlling hyperglycemia in pregnancy for women affected by GDM.

The innate immune system plays a significant role in onset of parturition. Maternal antenatal physical activity can influence immune function and timing of labor. We examined physical activity patterns and concentration of 19 cytokines at 16 and 27 weeks gestational age (GA), in peripheral plasma of 28 asymptomatic women who later had spontaneous preterm labor (SPTL, <37 weeks GA) and 52 women who later delivered at term (TL; ≥37 weeks GA). This nested case-control study used data from the Ontario Birth Study cohort. Exercise was assessed using the International Physical Activity Questionnaire, and cytokines were analyzed using Luminex assays. There was no significant difference in exercise patterns between SPTL and TL subjects. Plasma concentration of interleukin(IL)-10) was significantly higher in SPTL women at 16 and 27 weeks; while TNFα, IL-8, and MCP1 concentrations were increased at 27 weeks GA (p<0.05). Concentration of IL-10 was negatively correlated with the amount of reported walking (ρ=-0.264, p=0.03). Women should be encouraged to partake in low-intensity exercise throughout pregnancy, as it may confer a protective effect against SPTL through IL10-mediated pathways. Additionally, plasma cytokine analysis at 27 weeks GA may be useful for predicting SPTL in asymptomatic women. Novelty bullets: 1. In women that delivered preterm, plasma levels of anti-inflammatory cytokine IL-10 were significantly elevated at 16 and 27 weeks of gestation,; 2. Plasma levels of IL-10 was negatively correlated with the amount of reported walking; 3. Concentration of IL-8, MCP-1 and TNFa were increased in plasma of asymptomatic women that subsequently deliver preterm.
