Female metabolism, nutrition and exercise with Prof Abbie Smith-Ryan

*The information in this podcast is intended for Healthcare Practitioners. Nutrition and exercise recommendations are often generic and seldom consider sex differences, let alone the effect of fluctuating sex hormones that occur through ovulatory cycle or reproductive phases. Exercise physiologist and nutrition researcher, Professor Abbie Smith-Ryan, joins the podcast to shed light on the under-recognised effect of sex hormones on women’s metabolism, nutrition and exercise performance. Listen in as Abbie discusses the influence oestrogen and progesterone have on female physiology, such as impacts mitochondrial function, muscle fibre type, bone structure and body composition. Zooming out, Abbie highlights a holistic view and discusses how perimenopausal women can often experience undesirable changes in body composition and performance which can be both a cause and effect of psychological distress during this life stage. Abbie also explores the subtle but meaningful impact fluctuating sex hormones have on macronutrient metabolism and exercise performance in the ovulatory and luteal phase in cyclic women – all of which can have real world impact on the food women eat or how they feel and perform at different stages of their cycle. Finally, in a ‘speed round’, Abbie briefly outlines the lesser-known benefits of several nutrients in the context of women’s health and performance. Links: Smith-Ryan AE, Cabre HE, Moore SR.
