My name is Sarah O'Connell and I am a nursing student at the University of North Dakota College of Nursing. I have a client who is expecting and very anxious to breastfeed who raised the question of exercise and breastfeeding. I searched the archives and researched the topic and still would appreciate your thoughts on the issue and any other comments or questions you may have. Lovelady (1990) noted that exercise has little effect on milk production. According to Wallace (1992), his research found the milk expressed after-exercise to be higher in lactic acid. He also compared the babies' acceptance of the before-exercise milk with the milk expressed after their mothers exercised and found the babies to be less accepting of the after-exercise milk. One limitation of this study was the fact that these babies were fed with medicine droppers, a new feeding method for them. In Dewey and McCrory's (1994) study, they found that exercise during breastfeeding is safe for most women. Taking this information into consideration, I am interested to know if anyone has noticed in their practice a great incidence of exercise and problems with babies' acceptance of after-exercise milk or if anyone has any new information. It would be greatly appreciated. Thank You, Sarah O'Connell, College of Nursing student (University of North Dakota). Lovelady, C. (1990). Lactation performance of exercising women.
