The purpose of this study was to determine the effect of exercise during pregnancy in sedentary women with obesity on longitudinal changes in long-chain acylcarnitine (LC-AC) concentrations. We hypothesized that exercise training would significantly decrease circulating LC-ACs throughout gestation compared to a non-exercise control group. Pregnant women with obesity considered otherwise healthy [n=80, mean ± SD; body mass index (BMI): 36.9±5.7 kg/m2] were randomized into an exercise (n=40, aerobic/resistance 3x/week, ~13th gestation week until birth) or a non-exercise control (n=40) group. At gestation week 12.2 ± 0.5 and 36.0 ± 0.4, a submaximal exercise test was conducted, and indirect calorimetry was used to measure relative resting energy expenditure (REE), as well as respiratory exchange ratio (RER) at rest. Fasting blood samples were collected and analyzed for LC-AC concentrations. Fitness improved with prenatal exercise training; however, exercise training did not affect circulating LC-AC. When groups were collapsed, LC-ACs decreased during gestation (combined groups, P < 0.001), whereas REE (kcal·kg-1·d-1, P = 0.008) increased. However, average REE relative to FFM (kcal·kgFFM-1·d-1) and RER did not change. There was an inverse relationship between the change in RER and all LC-ACs (except C18:2) throughout gestation (C14: r = -0.26, P = 0.04; C16: r = -0.27, P = 0.03; C18:1: r = -0.28, P = 0.02). In summary, a moderate intensity exercise intervention during pregnancy in women with obesity did not alter LC-ACs concentrations versus control, indicating that the balance between LCFA availability and oxidation neither improved nor worsened with an exercise intervention.

ABSTRAKSelama kehamilan pikiran dan tubuh ibu hamil mengalami berbagai perubahan. Perubahan fisik yang muncul mengakibatkan ibu mengalami beberapa keluhan nyeri pada punggung bagian belakang, badan terasa lebih lemas, dan mudah lelah. Prenatal gentle yoga dan relaksasi dapat dilakukan selama kehamilan dapat membantu meningkatkan kesejahteraan ibu. Berdasarkan wawancara dengan kader kesehatan di Wilayah  kelurahan Gunung Lingkas Tarakan ibu hamil sering mengeluhkan badan terasa pegal – pegal, nyeri punggung dan kaku, selain itu ibu hamil di wilayah ini belum pernah mengikuti senam selama hamil.  Kegiatan ini berlangsung di kelurahan Gunung Lingkas Tarakan. Latihan prenatal gentle  yoga dan relaksasi dapat mengurangi keluhan keluhan yang muncul pada kehamilan, serta dapat membantu membuat ibu lebih tenang dan rileks selama kehamilan, serta membantu mempersiapkan ibu dalam menghadapi persalinanya menjadi lebih tenang, mudah dan lancar. Kata kunci: prenatal gentle yoga; rileksasi. ABSTRACTDuring pregnancy, the mind and body of a pregnant woman undergo various changes. The physical changes that appear cause the mother to experience several complaints of pain in the back, the body feels weaker, and gets tired easily. Prenatal gentle yoga and relaxation can be done during pregnancy can help improve the well-being of the mother. Based on interviews with health cadres in the Gunung Lingkas sub-district, Tarakan, pregnant women often complain of body aches, back pain and stiffness, besides that pregnant women in this area have never participated in exercise during pregnancy. This activity took place in the village of Gunung Lingkas, Tarakan. Gentle yoga and relaxation prenatal exercises can reduce complaints that arise in pregnancy, and can help make mothers calmer and more relaxed during pregnancy, and help prepare mothers to face childbirth to be calmer, easier and smoother. Keywords: prenatal gentle yoga; relaxation

Purpose: Wnt pathway is closely related to neurodevelopmental process associated with cognitive function. After administration of valproic acid to the pregnant mice, the effect of swimming exercise of pregnant mice on the memory, neuronal production, and apoptosis of pups was studied in relation with Wnt/β-catenin signaling pathway.Methods: On day 12 of pregnancy, mice were injected subcutaneously with 400-mg/kg valproic acid. The pregnant mice in the control with swimming exercise group and in the valproic acid injection with swimming exercise group were allowed for swimming for 30 minutes one time per a day, repeated 5 days per a week, during 3 weeks. Step-through avoidance task and Morris water maze task for memory function, immunohistochemistry for 5-bromo-2’-deoxyuridine (BrdU)-positive cells and western blot for brain-derived neurotrophic factor (BDNF), Wnt, β-catenin, Bcl-2 related X protein (Bax), B-cell lymphoma 2 (Bcl-2), cleaved caspase-3 were carried out.Results: Maternal swimming exercise during pregnancy improved memory function, increased BDNF expression, and neuronal proliferation in the valproic acid injected pups. Maternal swimming exercise during pregnancy suppressed Wnt expression and phosphorylation of β-catenin in the valproic acid injected pups. Maternal swimming exercise inhibited Bax and cleaved caspase-3 expression and increased Bcl-2 expression in the valproic acid injected pups.Conclusions: Maternal swimming exercise during pregnancy improved memory function by increasing cell proliferation and inhibiting apoptosis through Wnt/β-catenin signaling cascade activation in the valproic acid injected pups. Maternal swimming exercise during pregnancy may have a protective effect on factors that induce autism in the fetus.

For apparently healthy pregnant women, regular physical activity is recommended. The American College of Obstetricians and Gynecologists (ACOG) created recommendations for physical activity and exercise during pregnancy in 1985. At that time, pregnant women were advised to not exceed a heart rate of 140 beats per minute with physical activity. The heart rate recommendation was subsequently removed with the recommendations published in 1994, 2002, and 2015. In 2020, the ACOG updated its recommendations on physical activity for pregnant and postpartum women. The recommendation included exercising at a “fairly light to somewhat hard” perceived intensity and at less than 60–80% of age-predicted maximum heart rate, usually not exceeding a heart rate of 140 beats per minute. Women often seek advice from healthcare providers on physical activity during pregnancy, yet providers report concern about giving appropriate physical activity guidance. This paper summarizes the key scientific literature on monitoring absolute and relative exercise intensity in relation to the current ACOG recommendations, providing background on intensity-related concepts used in the recommendation. This paper also provides practical guidance to assist healthcare providers in relaying this information to pregnant women.

Abstract Background There are limited data on long-term outcomes of children whose mothers have followed exercise interventions during pregnancy. The aim of this paper was to investigate whether regular moderate intensity exercise during pregnancy affected the children’s body mass index (BMI) and physical activity (PA) at 7 years of age, and determine the relationship between children’s and mothers’ BMI and PA. Methods This was a follow-up of a multicentre randomised controlled trial, carried out at St. Olavs Hospital, Trondheim University Hospital, and Stavanger University Hospital, Norway (2007–2009 and 2014–2016). Women were randomised to follow a 12-week structured exercise protocol or standard antenatal care during pregnancy. At the 7-year follow-up, parents reported their child’s height, weight, and PA. The mothers also reported their own weight and PA. Main outcome variables were BMI, frequency and duration of moderate to vigorous PA (MVPA), and intensity of PA. Results A total of 855 women were randomised to exercise (n = 429) or standard antenatal care (n = 426) during pregnancy. At follow-up, 164 (38.2%) children and mothers in the intervention group and 117 (27.5%) in the control group participated. We found no group differences in the children’s iso-BMI or PA. Findings were similar when we performed stratified analyses by sex, except boys in the control group spent more time on electrical devices than boys in the intervention group. Subgroup analyses of children of mothers who adhered to the exercise protocol and sensitivity analyses excluding children born preterm, children admitted to the neonatal intensive care unit, and children with diseases or health problems at the 7-year follow-up, did not change the results. Children’s BMI, weekly leisure time MVPA and intensity of PA correlated with mothers’ BMI, daily exercise, and intensity of exercise. Conclusions Regular moderate intensity exercise during pregnancy did not affect BMI or PA of the children at 7 years. Good maternal health should be encouraged as it may influence the health of the next generation. Trial registration The initial RCT study was registered in ClinicalTrials.govNCT00476567.
