Physiological response during exercise is preserved in children exposed to a suboptimal gestational environment
Authors' conclusion
Children exposed to investigated SGFs display a similar physiological response regarding ME and substrate oxidation during rest and exercise compared to nonexposed children. Future studies should confirm these novel results and continue investigating other research avenues to explain the higher risk of obesity in this population.
Study context
- Population
- Children aged 8 to 10 years, Quebec Adiposity and Lifestyle Investigation in Youth cohort; incremental maximal cycling test with indirect calorimetry
- Participants
- 68 / 49 / 77 / 370
- Exposure
- Children exposed to suboptimal gestational factors (SGFs) vs nonexposed children
- GDMn = 68
- Hypertensive disordersn = 49
- Maternal smokingn = 77
- Nonexposedn = 370reference
- Outcome
- Mechanical efficiency (ME) and substrate oxidation during rest and exercise
Main finding
As reported in the abstract
- Mechanical efficiency (ME) during submaximal effort; no difference
- F[3,540] 0.46; P = 0.713
- ME during maximal effort; no difference
- F[3,545] 0.86; P = 0.463
- % contribution of lipids and carbohydrates at rest; did not differ
- F[3,545] 1.68; P = 0.169
- % contribution of lipids and carbohydrates during submaximal exercise; did not differ
- F[3,544] 0.31; P = 0.534
Observational data: associations, not effects.
