“…Exercise training followed in this study consisted mainly of light resistance and toning exercises, whereas earlier exercise intervention trials in pregnant women focused mainly on aerobic exercises such as stationary cycling, [46][47][48][49][50][51] walking, [52][53][54] or other exercise modalities such as stretching, 53 and only one non-randomised study included weight lifting and strength conditioning. 55 There is compelling evidence that improved muscular strength has beneficial effects in the prevention of chronic diseases, as well as in the ability to cope with daily living activities in both healthy and diseased people.…”

Objective: We examined the effect of light intensity resistance exercise training performed during the second and third trimester of pregnancy on the newborn's birth size. We also studied the association between maternal body weight prior to pregnancy and newborn's birth size. Design: Randomised controlled trial. Subjects: We randomly assigned 160 sedentary gravidae to either a training (n ¼ 80) or a control (n ¼ 80) group. The training programme focused on light resistance and toning exercises (three times per week, 35-40 min per session). We recorded the Apgar score, birth weight, birth length, and head circumference of the newborn, as well as gestational age at time of delivery from hospital perinatal records. We also measured maternal weight and height before parity and gestational weight gain. Results: Maternal characteristics neither differed between groups (all P40.1) nor newborn characteristics (all P40.1). Maternal body weight was positively and significantly associated with newborn's birth weight and length only in the control group (b ¼ 19.20 and 0.065, respectively, Po0.01). Conclusion: Light intensity resistance training performed over the second and third trimester of pregnancy does not have a negative impact on the newborn's body size or overall health. Exercise interventions might attenuate the adverse consequences of maternal body weight before pregnancy on the newborn's birth size.

“…Jackson and colleagues 3 showed villi, steam villi and total peripheral villi increase among women who continued moderate exercise training through pregnancy. Others also showed interesting placental morphology adjustments both trained and sedentary pregnant women [4][5][6] . However, many methodological issues such as few patients' number, gestational age at beginning and others might influence outcomes.…”

Physical exercise has been demonstrated a positive effect on many pregnancy outcomes. Placental components are important for exchanging oxygen and nutrients between mother and fetus. This study aimed to systematic review and meta-analysis whether physical exercise could induce a morphological adjustment on placenta components. We systematically searched PubMed database until October 30 th , 2014. We included randomized and non-randomized studies with control group, which aimed to investigate the effect of the physical exercise (water, aerobic and resistance) on placental components (placental weight and volume, villous volume and vascular volume, intervillous space and stem villi). Initially, we identified 222 articles, of which 9 articles were used for full text analysis. Finally, four articles were included in the systematic review and meta-analysis. Meta-analysis demonstrated that exercise appeared to affect placental weight (95% CI, [4.25-7.75]). Apparently, physical exercise has a positive effect on placental components. However, this conclusion is based on a limited number of studies. Clearly, it stands the necessity of larger samples and better methodology quality.Keywords: placenta, chorionic villi, physical exertion, pregnancy.

Componentes da placenta são importantes para a troca de oxigênio e nutrientes entre mãe e feto. O objetivo deste estudo foi revisar de forma sistemática e realizar uma meta-análise para verificar se o exercício físico pode induzir um ajuste morfológico nos componentes da placenta. A pesquisa foi feita sistematicamente no banco de dados PubMed até 30 de outubro de 2014. Foram incluídos estudos randomizados e não-randomizados com grupo controle, que tiveram como objetivo investigar o efeito do exercício físico

“…Unlike our findings, a study conducted with pregnant women who exercised during pregnancy showed that their children were born weighing more than the children of sedentary mothers. 18 Likewise, Clapp et al 19 highlighted that adequate physical exercise throughout the whole human pregnancy, or part of it, may contribute to the increase in fat percentage, weight, and head circumference of children. However, the physical training protocol used in the study by Clapp et al 19 differs from that used in the present study: the maximum aerobic capacity corresponded from 55 to 60%, the physical training lasted for 20 min, from three to five times a week, and the physical exercise included the use ladder or stool.…”

Objective: To evaluate the effects of physical training of mother rats during pregnancy associated with a low-protein diet offered during pregnancy and lactation on the development and growth of the femur of their offspring.Methods: Forty 90-day old male Wistar rats were divided into four groups: pups of sedentary nourished mothers, pups of sedentary malnourished mothers, pups of trained nourished mothers, and pups of trained malnourished mothers; all groups included 10 rats. Physical training on a treadmill for 8 weeks, 5 weeks before conception and 3 weeks in the gestational period for mother rats of pups of trained nourished mothers and pups of trained malnourished mothers. Induction of low-protein diet to the mother rats during pregnancy and lactation for the groups of pups of sedentary malnourished mothers and trained malnourished mothers. After the pups were sacrificed, on the 90th day of life, we analyzed weight, length, and femoral bone mineral content.Results: Decreased body weight, femur weight, and femur length (p < 0.05) were observed for the groups of pups of sedentary malnourished mothers and trained malnourished mothers in comparison with to the groups of pups of sedentary nourished mothers and trained nourished mothers, respectively. There was no difference in bone mineral content of the femur in either of the groups. Conclusion:Mild physical training on the treadmill during pregnancy does not interfere with bone development and growth of the offspring. However, protein malnutrition during this period and during lactation promotes permanent damage to the bone structure of the offspring.
