The article assesses differences in ratings of perceived exertion (RPE) and oxygen uptake behavior during water and land-based exercise performed in exercise intensity of first ventilatory threshold between pregnant and non-pregnant women. RPE is reportedly the relative tension occurring in the mascular, nervous and cardiovascular systems during physical activity. Results showed no significant difference between RPE or oxygen uptake when comparing water with land-based exercise.

Introduction C-reactive protein (CRP) during pregnancy has been associated with adverse maternal outcomes such as preeclampsia and gestational diabetes mellitus. Increased physical activity and exercise training have shown to decrease circulating levels of CRP. The association between maternal exercise and CRP has not been adequately investigated. Objective To review the literature to investigate the maternal exercise effects on CRP responses during pregnancy. Methods This systematic review was designed according to PRISMA (PROSPERO registration CRD42016039618). Eligible studies were identified from MEDLINE, EMBASE, Web of Science, Scopus, COCHRANE CENTRAL, Scielo and SportDiscus up to May 2016 without year of publication and language limitations. The main MeSH terms were the following: “exercise”, “motor activity”, “physical activity”, “pregnancy”, “gestational”, “maternal” and “C-reactive protein”. Inclusion criteria were studies conducted in pregnant women who were engaged in any type of exercise or physical activity and report CRP values. The extraction and risk of bias assessment were carried out by two independent reviewers. A total of 344 studies were found, 147 of which were excluded as duplicates, and 191 studies were excluded based on title, abstract and full-text. Six studies met the inclusion criteria and were included in the present systematic review. Results Across six studies, 1276 pregnant women were included. The maternal exercise intensity ranged from light to vigorous. Out of six studies, two were randomized controlled trials that reported decrease in maternal CRP concentrations after an exercise intervention. Four studies were prospective observational studies that reported no difference in maternal CRP values with exercise (one study) or decrease in maternal CRP values when the exercise was added to the prenatal standard care. Conclusion In conclusion, the majority of the studies found in the present systematic review reported a decrease in CRP concentrations after an exercise intervention before or during pregnancy. These responses indicate a trend towards a protective effect of exercise and physical activity on inflammation during pregnancy. Disclosure of interest None declared. [ABSTRACT FROM AUTHOR]

Objectives To verify the behavior of glycosylated hemoglobin (HbA1c) and homeostasis model assessment (HOMA), which assesses insulin resistance from insulin and fasting glucose levels in pregnant women with GDM after an aerobic training on a cycle ergometer. Methods Randomized clinical trial where mothers with GDM are randomly allocated to the intervention group (IG), which is part of a program of regular aerobic exercise with 50-min sessions, three times a week for 10 weeks, or the control group (CG), which makes stretching and relaxation sessions with 50 min once a week for 10 week. The groups are selected from prenatal clinics in the Hospital de Clinicas de Porto Alegre. Results At this moment, six patients completed the proposed trainings, two in the intervention group and four in the control group. We will only describe the data, since the present study is still in progress, under recruitment of pregnant women. The average age of IG is 30.5 ± 9.2 years and in CG 27.5 ± 8.7 years. Four are primiparous and two are pregnant for the fourth time. At baseline, the overall mean HbA1c is 5.2 ± 0.5 and 6.1 ± 2.0 HOMA. After the intervention of 10 weeks, the overall mean HbA1c is 5.5 ± 0.4 and 6.3 ± 4.0 HOMA. The mean gestational age at IG and CG is the same, 38 weeks and 5 days ± 1 day. Weight and height of the newborn IG was 3620.0 ± 714.2 g and 49.5 ± 2.1 cm, respectively, and in controls was 4037.5 ± 180.5 g and 50.8 ± 2.2 cm, respectively. Conclusions After 10 weeks of training we noticed an increase in mean HbA1c and HOMA, compared to baseline, and that the intervention group delivered lighter and smaller babies. Disclosures J.G.
