BackgroundDuring pregnancy, a sedentary lifestyle may have negative consequences on maternal and foetal health status. The main objective of this project is to assess the effects of an exercise intervention in overweight and grade I obese pregnant on maternal and foetal health markers.Methods/designThe present study aims to recruit 60 overweight and grade I obese women interested in participating in an exercise intervention program from the 17th gestational week until delivery. Women will be randomized to either an exercise (three 60-min sessions/week of combined aerobic and strength training and pelvic floor exercises), or usual care (control) group (30 women per group). The primary outcome measures are maternal weight gain, and maternal and neonatal glycaemic profile. Secondary outcome measures are: i) perinatal obstetric records; i) body composition; iii) dietary patterns; iv) physical fitness; v) low-back pain; vi) objectively measured physical activity and sedentary behaviour; vii) haematology and biochemical analyses; viii) oxidative stress; ix) pro- and anti-inflammatory markers; x) bone health biomarkers; xi) sleep quality; xii) mental health, quality of life and positive health.DiscussionThe findings of this project will help to identify strategies for primary prevention and health promotion based on this exercise-based intervention program among overweight and grade I obese pregnant women.Trial registration NCT02582567; Date of registration: 20/10/2015
The aim of the present study was to analyze the influence of a supervised concurrent exercise-training program, from the 17th gestational week until delivery, on cytokines in maternal (at 17th and 35th gestational week, and at delivery) and arterial and venous cord serum. Fifty-eight Caucasian pregnant women (age: 33.5 ± 4.7 years old, body mass index: 23.6 ± 4.1kg/m2) from the GESTAFIT Project (exercise (n = 37) and control (n = 21) groups) participated in this quasi-experimental study (per-protocol basis). The exercise group followed a 60-min 3 days/week concurrent (aerobic-resistance) exercise-training from the 17th gestational week to delivery. Maternal and arterial and venous cord serum cytokines (fractalkine, interleukin (IL)–1β, IL-6, IL-8, IL-10, interferon (IFN)–γ, and tumor necrosis factor (TNF)–α) were assessed using Luminex xMAP technology. In maternal serum (after adjusting for the baseline values of cytokines), the exercise group decreased TNF-α (from baseline to 35th week, p = 0.02), and increased less IL-1β (from baseline to delivery, p = 0.03) concentrations than controls. When adjusting for other potential confounders, these differences became non-significant. In cord blood, the exercise group showed reduced arterial IL-6 and venous TNF-α (p = 0.03 and p = 0.001, respectively) and higher concentrations of arterial IL-1β (p = 0.03) compared to controls. The application of concurrent exercise-training programs could be a strategy to modulate immune responses in pregnant women and their fetuses. However, future research is needed to better understand the origin and clearance of these cytokines, their role in the maternal-placental-fetus crosstalk, and the influence of exercise interventions on them.
AimTo analyse i) the association of physical fitness during early second trimester and late pregnancy with maternal and neonatal outcomes; and ii) to investigate whether physical fitness is associated with the type of birth (vaginal or caesarean section). MethodsPregnant women from the GESTAFIT Project (n = 159) participated in this longitudinal study. Maternal physical fitness including upper-and lower-body strength, cardiorespiratory fitness (CRF) and flexibility were measured through objective physical fitness tests at the 16 th and 34 th gestational weeks. Maternal and neonatal outcomes were collected from obstetric medical records. Umbilical arterial and venous blood gas pH and partial pressure of carbon dioxide (PCO 2 ) and oxygen (PO 2 ), were assessed.

Resilience and catastrophizing, through distress, are related to fibromyalgia severity. Active lifestyle, directly and through fitness and fatigue, is related to fibromyalgia severity. Declarative memory (objectively measured) is not related to fibromyalgia severity. Subjective and objective assessments of fitness provide complementary information in fibromyalgia.
Objectives:To analyze the association of sedentary time and physical activity (PA) intensity levels with immunometabolic markers during early pregnancy; and to examine if meeting the PA recommendations is associated with the immunometabolic profile of pregnant women. Methods: Fifty Caucasian pregnant women (age: 32.8 ± 4.7 years old, body mass index: 24.2 ± 4.1kg/m 2 , gestational age: 17 ± 1.5weeks) participated in this crosssectional study (from September 2015 through May 2016). Sedentary time and PA intensity levels were objectively measured with triaxial accelerometer (seven consecutive valid days). Fasting serum glucose, total cholesterol, phospholipids, and triglycerides were assessed with standard methods. Serum pro-inflammatory and anti-inflammatory cytokines (fractalkine, interleukin-1β, interleukin-6, interleukin-8, interleukin-10, interferon-γ, and tumor necrosis factor-α) were measured using Luminex xMAP technology. Results: Sedentary time and PA were not correlated with any glycemic or lipid marker (P > .05). After adjusting for the potential confounders, vigorous PA showed a positive non-significant association with interleukin-6 (P = .06), and bouts of moderatevigorous PA was inversely associated with interleukin-1β and interferon-γ (P = .02 and P = .04, respectively). Meeting the PA guidelines was inversely associated with interleukin-1β and positively associated with interleukin-8 (P = .01 and P = .04, respectively). These associations disappeared after controlling for multiplicity. | 149ACOSTA-MANZANO eT Al. | 157ACOSTA-MANZANO eT Al.Víctor Segura-Jiménez https://orcid.
Aim: (a) To analyse the association of objectively measured sedentary time (ST) and physical activity (PA) during early second trimester of pregnancy with maternal and neonatal birth outcomes; (b) to explore if ST and PA differ between women with vaginal or caesarean section deliveries. Methods: Ninety-four Caucasian pregnant women (32.9 ± 4.6 years old) participated in this prospective longitudinal study. Triaxial accelerometers were used to assess ST and PA intensity levels for seven consecutive days during second trimester of pregnancy. Birth data were collected from the obstetric medical records. Umbilical cord arterial and venous blood gas (pH, partial pressure of carbon dioxide and oxygen, and oxygen saturation) were analysed after birth. Results: After adjusting for potential confounders, greater ST was associated with higher arterial and venous cord blood partial pressure of carbon dioxide and more acidic arterial and venous pH (all, P < 0.01). Moderate PA, moderate-to-vigorous PA (MVPA), total PA and steps per day were positively associated with arterial cord blood oxygen saturation (all P < 0.05). Steps per day were inversely associated with gestational age at birth (P < 0.01), and duration of first stage of labor (P < 0.05).Total and light PA were associated with a more alkaline pH in umbilical vein (all, P < 0.01). Vigorous PA was inversely associated with the Apgar score (P < 0.01). No significant differences were observed in ST and PA levels between women with vaginal and women with caesarean section deliveries (all, P > 0.10). Conclusion: Increasing PA and decreasing ST during pregnancy might promote better maternal and neonatal birth markers.

Highlights Greater moderate-to-vigorous physical activity is modestly associated with decreased symptoms of depression in pregnancy. Higher levels of sedentary time were negatively associated with positive affect in pregnancy. Enhanced upper-body flexibility is modestly associated with better emotional regulation in pregnancy. Additional experimental research is warranted to confirm or refute these findings.
Aims To explore the association of self‐reported physical fitness with bodily, lumbar and sciatic pain, and pain disability during pregnancy. Methods The present study sample comprised 159 pregnant women (32.9 ± 4.7 years old). Self‐reported physical fitness was assessed with the International Fitness Scale (IFIS), where higher scores indicate greater physical fitness. Bodily pain was assessed with the 36‐Item Short Form Health Survey (SF‐36), where higher scores indicate lower pain. Lumbar and sciatic pain were measured with a visual analogue scale (VAS). The Oswestry Disability Index (ODI) questionnaire was employed to assess the disability resulting from pain. Measures were assessed at 16th and 34th gestational weeks (g. w.). Results Pregnant women showed low‐moderate pain during pregnancy course. Most of them showed medium self‐reported overall physical fitness. At 16th g. w., greater self‐reported overall physical fitness and cardiorespiratory fitness were associated with less bodily and lumbar pain, and pain disability (all, P < 0.05). Greater muscular strength was associated with less bodily pain and pain disability (both, P < 0.05). Greater speed‐agility was associated with less bodily pain (P < 0.01) and less pain disability (P < 0.05). Self‐reported flexibility was not associated with any outcome (P > 0.05). At 34th g. w., greater overall physical fitness and its components were associated with less bodily and sciatic pain (all, P < 0.05). Conclusion Greater self‐reported overall physical fitness and its components are associated with less bodily, lumbar and sciatic pain, and reduced pain disability during pregnancy. Future studies are needed to explore whether increasing physical fitness before and during pregnancy could decrease pain in this relevant stage.
