#77 - Exercise and pregnancy with Professor Margie Davenport
Inside Exercise
Muscle biopsy study and dietary considerations for pregnant athletes
Discussion on a muscle biopsy study revealing that older individuals, especially females, tend to complain less about biopsies, potentially due to the influence of past experiences such as difficult pregnancies or childbirth.
Dr Glenn McConell chats with Professor Margie Davenport from the University of Alberta, Canada. She is an expert on exercise and pregnancy. We discussed the effect of pregnancy on the health (including pre-eclampsia and gestational diabetes) and exercise performance of the mother and on the health of the fetus during pregnancy and the offspring after pregnancy. It became very clear that there needs to be more focus on the beneficial effects of exercise before and during pregnancy on both the mother and the fetus/offspring. A very interesting chat.
