摘要

Objectives: To evaluate physical efficiency and activity energy expenditure (AEE) in term pregnancy females during cardiopulmonary exercise tests with a supine cycle ergometer.Material and methods: The study comprised 22 healthy full-term pregnancy women with uncomplicated pregnancies hospitalized in the Department of Gynecology and Obstetrics, Specialist Teaching Hospital in Tychy, Poland. All subjects underwent cardiopulmonary exercise tests (CPET) on a supine cycle ergometer. The 12-min, three-stage, progressive, symptom-limited submaximal test protocol (up to 80% HRmax) was used. Pulsometry was used to record HR on a beat-to-beat analysis and to calculate AEE. Respiratory responses were measured by ergospirometer and a computer system on a breath-by-breath basis at rest, during exercise and at restitution.Results: In the studied population, VO2max was established at the level of 2.190.33L/min in ergospirometry and 2.04 +/- 025L/min in pulsometry. Physical efficiency calculated for sub-maximal exercise by use of the Davis equation was 30.52 +/- 0.12%. AEE, based on VO2 in various phases of the CPET, was 0.47, 0.71 and 0.88L/min for phases 25, 50 and 75 W. Based on ergospirometer readouts, AEE was 10.60, 16.11 and 20.94kJ/min for phases 25, 50 and 75 W. Overall mean AEE (determined by pulsometry) was 10.59 kJ/min. CPET testing did not have any negative effect upon the health or life of the neonates involved in the study.Conclusions: Submaximal CPET up to 80% HRmax with a supine cycle ergometer is a safe and precise method for assessing work efficiency in term pregnancy women.
