Acute Effects of Endurance Exercise on Breast Milk Composition in Women With Overweight/Obesity
Norway32 participantsStarted 2023-03-01
Plain-language summary
The investigators will determine the acute effect of exercise on breastmilk composition. Participants will come in to the lab on three different days, out of which they will exercise on two of these days and rest in the lab on the third day. The conditions will be randomly allocated to each participant. Breastmilk samples will be obtained in the morning of each test day, as well as immediately after, one hour after and four hours after the exercise/rest condition. Dietary intake will be standardized on the test days.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This study looked at how endurance exercise affects breast milk composition in women who are overweight or obese — since it's now completed, has my doctor seen any of the findings, and do they change any recommendations about exercising while I'm breastfeeding?
2The trial specifically measured metabolites in breast milk after exercise — are there any known substances in breast milk that could be affected by intense workouts, and should I be timing my feeds or pumping sessions around exercise just to be safe?
3Since this was a research study rather than a treatment trial, how does my doctor weigh the emerging evidence about exercise and breast milk against standard breastfeeding guidance for someone at my weight?
4The study focused on women with overweight or obesity — given my own situation, does my doctor think the results would apply to me, and are there any particular changes in milk composition I should watch for if I start a new exercise routine while breastfeeding?
5Are there any practical steps, like pumping before exercising or waiting a certain amount of time after a workout before nursing, that my doctor would suggest while this research is still being reviewed and published?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
