Key result
Swimming resulted in a 9% lower peak O2 uptake compared with cycling, but peak O2 uptake was not significantly affected by pregnancy in either exercise modality.
Why the study?
Does swimming compared to cycling affect peak O2 uptake in pregnant and postpartum women?
Population
11 women studied at 30-34 weeks gestation and 8-12 weeks postpartum
Comparison
Swimming vs Cycling
Design
Cohort
Follow-up
from 30-34 weeks gestation to 8-12 weeks postpartum

Supports aerobic capacity maintenance in pregnancy for both modalities; hypothesis-generating and should not yet change exercise testing practice.

Does swimming compared to cycling affect peak O2 uptake in pregnant and postpartum women?
Effect estimate: 9% lower
Pregnancy does not affect peak oxygen uptake during cycling or swimming, though swimming elicits a lower peak oxygen uptake than cycling.
Spinnewijn et al. (1996) conducted an observational in Pregnancy (n=11). Swimming vs. Cycling was evaluated on Peak O2 uptake (VO2peak) (9% lower). Swimming resulted in a 9% lower peak O2 uptake compared with cycling, but peak O2 uptake was not significantly affected by pregnancy in either exercise modality.
