Clinical Trial 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.
