Ana Mateos,


This dataset contains records of an experimental research project (BioE6-CEIC 1595) on the energetic cost of walking in pregnant women during the last trimester of gestation. The experimental trials were performed in a sample of 31 urban women, aged 28 to 44 years, in the 28th and 32nd weeks of gestation. The dataset also contains some anthropometrical and body composition data of the females. Metabolic rates were recorded in the different resting and walking tests during the 28th and 32nd weeks of gestation. All the experiments were performed indoors, at the BioEnergy and Motion Lab (LabBioEM) of National Research Center on Human Evolution (CENIEH, Spain), in 2016 and 2017. The description of the recorded variables is included in the data and document files.


Steps to reproduce

Women were required to fast overnight prior to having their metabolic measurements, taken in a post-absorptive state in the morning. The experiments were conducted indoors, at the Bioenergy and Motion Lab (LabBioEM) of the National Research Center on Human Evolution (CENIEH, Burgos, Spain), under standard conditions of temperature (21.5ºC-23ºC) and humidity (29%-31%). Women came to LabBioEM twice, one session at 28th week, and second session, at 32nd week of gestation. The following standardized protocols were applied:  - An Anthropometric Protocol was performed following normalised standards. Height (in cm) was measured to the nearest 0.1 cm with a Harpenden stadiometer (Holtain Limited). Body mass (Weight, in kg) was obtained with a digital scale to the nearest 0.1 kg.  - A Body Composition Protocol was applied, in accordance with the normalised procedure established in the Consensus Conference of the National Institutes of Health (NIH, 1996), with a tetra-polar analyser vector of body impedance, BIA 101 AKERN©, and the software BodyGram Pro© (v2010). The proportion of fat mass (FM), fat-free mass (FFM), and total body water (TBW) was obtained.  - An Indirect Calorimetry Protocol was carried out with an ergospirometer Master Screen-CPX JAEGER® and the LabManager© IntelliSupport 5.72 software application. The resting metabolic rate (RMR) was measured during 30 minutes, with each participant laying back on a stretcher while wearing a breathing mask and a heart rate monitor. Walking tests (W20) were carried out on the treadmill during 20 minutes at a speed of 4 km/h. These metabolic rates were recorded during the 28th and 32nd weeks of gestation of participants (RMR_28, RMR_32, W20_28, W20_32).
