Pregnancy and Postpartum

Special Interest Group

Mission: To provide a forum for scientific and clinical communication regarding the maternal and fetal response to acute and chronic exercise during pregnancy, as well as the long-term implications for mother and child.

Our Purpose:

  • To provide a means by which members with a common interest in pregnancy (including pre-conception) and postpartum physical activity/exercise/sport, nutrition education, research, and clinical care for mother and infant may meet, confer, and promote these interests.

SIG of the Month

GSSI Pre-Conference

The Physiology of Hydration: More Than Water Alone

This session explores the physiology of hydration through an integrated lens—examining how carbohydrate, sodium, flavor, and fluid interact to influence intake, absorption, retention, and performance. We’ll review current research on fluid balance, osmotic drivers, and palatability, highlighting mechanisms that underpin voluntary intake and thermoregulation. Attendees will gain insight into individualized strategies, including sweat profiling and timing approaches, to optimize euhydration and mitigate performance decrements associated with >2% body-mass loss. Practical applications will be linked to laboratory- and field-based research, ensuring translation from bench to field. This pre-conference equips you with evidence-based tools to support athlete hydration across diverse environments and sporting contexts.
