Maternal Exercise

Very Low Risk for breastfeeding

Safe. Compatible.
Minimal risk for breastfeeding and infant.

Moderate exercise has a benefit for health and it is entirely suitable while breastfeeding. It does not affect composition of milk nor diminishes the amount produced, instead, it may be increased (Be'er 2020, CML 2012, HWA 2009).
Maternal exercise does not cause weight loss in the infant (Daley 2012, Su 2007, Dewey 1994).
Resistance and aerobic exercise may slow bone loss during lactation (Lovelady 2009).

Exhaustive exercise could decrease IgA and lactose secretion, and, increase lactic acid and protein content, which can alter milk flavor though well tolerated by the child (CML 2012, HWA 2009, Wright 2002, Quinn 1999, Carey 1997).

A continuos and intensive exercise would be advisable only for women who have undergone previous training, e.g. professional sport women.

Suggestions made at e-lactancia are done by APILAM´s pediatricians and pharmacists, and are based on updated scientific publications.
