Abstract
This study was conducted to determine the response of milk production to aerobic exercise in women suffering from low milk production during lactation. This study was carried out on forty healthy primiparous mothers, aged from 20 to 35 years old, and their body mass index (BMI) was 25-30 Kg/m2. They were randomly distributed into two equal groups: Control group received advices about the right way of lactation, mother’s nutrition and fluid intake, as well as breast massage; and study group received the same advices and engaged in a program of moderate aerobic exercise at 60 to 70 % of the maximum heart rate for 45 minutes, 3 days/week, for 8 weeks. Evaluation of all mothers were done pre and post treatment course through assessing milk content (fat, protein and lactose), the serum prolactin level, weight of the baby, and degree of improvement in the flow of milk. The results revealed that the control group showed a statistically no significant difference (p>0.05) in the fat, protein and lactose contents of milk, the serum prolactin level and degree of improvement in the flow of milk post treatment, while weight of the baby showed a statistically highly significant increase (p=0.0001). While the study group showed a statistically highly significant increase (P=0.0001) in the fat, protein and lactose contents of milk, the serum prolactin level, weight of the baby and the degree of improvement in the flow of milk. Compared to the control group, the study group showed a significant increase in the fat content (P=0.01) and a highly significant increase (P=0.0001) in the protein and lactose contents of milk, the serum prolactin level and the degree of improvement in the flow of milk, as well as, weight of the baby (P=0.004) post treatment. Therefore, it can be concluded that moderate intensity aerobic exercise can be used effectively to improve both the milk quantity and quality, which leads to normal weight gain of the newly born babies
