Narrative: Case study 27.8 summary
Moderate aerobic exercise has no adverse effects on the quantity or quality of breast milk produced by nursing mothers, and can significantly improve the mothers' cardiovascular fitness, researchers say.The study monitored 33 women for 12 weeks, beginning 6-8 weeks after the births of their children.All were exclusively breast-feeding their babies, and had not previously been exercising.18 women were randomly assigned to the exercise group and 15 to the non-exercise group.The women in the exercise group participated in individual exercise programs, including rapid walking, jogging or bicycling for 45 minutes per day, five days per week.The researchers found that: 1) women in both groups experienced the same amount of weight loss; 2) there was an important improvement in the aerobic fitness of the exercising mothers; and 3) there was no significant difference between the groups in terms of infant breast-milk intake, energy output in the milk, or infant weight gain.
