Creatine for Recovery and Thinking in Mothers (CREATE-MOM)

26. august 2026 opdateret af: University of North Carolina, Chapel Hill

Creatine for Recovery, Executive Function, Activity, Thinking & Energy in Mothers (CREATE-MOM)

The purpose of this randomized, double-blind, parallel-group trial is to compare the effects of two doses of creatine monohydrate (5 g/day versus 10 g/day) administered for four weeks in postpartum women. The study will evaluate exercise performance, post-exercise recovery, cognitive function, and brain creatine concentrations in a sub-sample.

Detaljeret beskrivelse

Postpartum women frequently experience changes in physical performance, recovery, cognition, sleep quality, and mood. Creatine supplementation may enhance energy availability in skeletal muscle and brain tissue, potentially improving exercise performance, recovery, and cognitive function. This study will enroll 40 postpartum women and randomly assign participants in a 1:1 ratio to receive either 5 g/day or 10 g/day of creatine monohydrate for four weeks in a double-blind fashion. Assessments will be conducted before and after supplementation and will include repeated sprint ability testing, skeletal muscle oxygen recovery, and cognitive testing. A subsample of 20 participants will undergo magnetic resonance spectroscopy to assess brain creatine stores.
