Effects of Exercise During Gestation on Maternal and Foetal Health (GESTAFIT)
Effects of Supervised Exercise During Gestation on Maternal and Foetal Health Markers. The GESTAFIT Project
The main objective of this project is to assess the effects of a novel and supervised exercise intervention in overweight pregnant and their newborn.
Methods/Design: The present study is a Randomized Controlled Trial. Sixty overweight pregnant interested in participate in the intervention program will be randomly assigned to either exercise (3 sessions/week), or to usual care (control) group (30 pregnant per group). The primary outcome measures are maternal weight gain, and maternal and neonatal glycaemic profile. Secondary outcomes measure are: i) body composition; ii) dietary patterns; iii) physical fitness; iv) objectively measured physical activity and sedentary behaviour; v) sleep quality; vi) mental health, quality of life and positive health; vii) haematology and biochemical analysis; viii) oxidative stress; ix) pro- and anti-inflammatory markers; x) bone health biomarkers; xi) adiposity-related proteins expression. The data will be analysed on an intention-to-treat basis and per protocol.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Exercise intervention
3 times per week from the 17th week of gestation until delivery
|
The exercise intervention will be performed in two groups so that each group will have 12-13 participants.The groups will train 3 days/week (60min per session) from the 16th week of gestation until delivery.
The exercise intervention group will go through different phases of training: a) Learning phase: which will involve the intervention plan, the goals we want to work, and how we will perform it; b) Movement Learning phase: theoretical and practical sessions with the explanation of movements and ergonomic basic patterns; and c) Physical Fitness Training phase: with training sessions aimed at improving fitness and weight loss, and training sessions focused on a correct pelvic mobilization for the delivery.The intensity will be adapted during the exercise program based on the week of gestation and each pregnant heart rate.
The sessions will consist of a mixed work, composed of circuits where both muscular and cardiovascular conditioning will be implemented.

Moreover, 4 genes highly involved in foetal and postnatal development of adipose tissue have been selected; two are receptors: the Glucocorticoid receptor and the PPAR-γ, and two are metabolic enzymes: beta-11 hydroxysteroid dehydrogenase type I or 11βHSD1, and 11 beta-hydroxysteroid dehydrogenase type II or 11βHSD2. Of great importance are PPAR-γ1 and PPAR-γ2, which are generated from the same gene by alternative promoter usage and mRNA. We will measure such proteins as well as paraoxonase/arylesterase 1 (PON1) concentrations in maternal and umbilical cord plasma by Polymerase Chain Reaction and Western Blot techniques. |
