Menstrual Cycle Hormonal Changes and Energy Substrate Metabolism in Exercising Women: A Perspective

This article discusses the research supporting that the hormonal changes across the menstrual cycle phases affect a woman's physiology during exercise, specifically addressing aspects of energy substrate metabolism and macro-nutrient utilization and oxidation. The overarching aim is to provide a perspective on what are the limitations of earlier research studies that have concluded such hormonal changes do not affect energy metabolism. Furthermore, suggestions are made concerning research approaches in future studies to increase the likelihood of providing evidence-based data in support of the perspective that menstrual cycle hormonal changes do affect energy metabolism in exercising women.
