Psychophysiological Responses to High-Intensity Interval Training Exercise over Menstrual Cycle Phases: An Exploratory Study.

Introduction: Although there is potential for the menstrual cycle to impact psychophysiological responses to exercise, there has been a paucity of studies investigating this aspect, specifically in the context of high-intensity interval training (HIIT).

Purpose: This exploratory study aimed to examine the psychophysiological responses to HIIT over the menstrual cycle.

Methods: Twenty-three healthy and physically active young women were recruited.
