This phase of the project aims to analyze the interaction between physical exercise and the phases of the menstrual cycle, evaluating its impact on fatigue, functional capacity, and exercise perception in women with and without Multiple Sclerosis. To achieve this, a controlled, single-blind, prospective, 2x3 crossover, randomized clinical trial will be conducted, involving women with Multiple Sclerosis (MS), matched by age, lifestyle habits (smoking, physical activity), and geographic location with a group of women without MS. This study, aligned with previous findings, seeks to deepen the understanding of the role of exercise in managing Multiple Sclerosis symptoms and to promote greater adherence to personalized physical activity programs adapted to the phases of the menstrual cycle.
