Pediatrics: 4/2002

A few months ago, I was asked by a breastfeeding mother whether it was OK for her to breastfeed after exercise.  There was a study done in 1991 that raised some eyebrows about the lactic acid contant in post-exercise milk .. and another study that suggested that  the kids actually seemed to refuse to take the milk.  But there may have been some confounding factors (the milk was expressed and fed to the kids by bottle!) … so this study was done to answer the question with some authority.   "Conclusion: These data support the hypothesis that moderate or even high-intensity exercise during lactation does not impede infant acceptance of breast milk consumed 1 hour postexercise.
