Effects of Menstrual Cycle Phase on Fat Oxidation During Exercise in Naturally Menstruating Women: A Systematic Review and Meta-Analysis

This systematic review will examine whether fat oxidation during exercise differs across menstrual cycle phases in naturally menstruating women. It will include studies comparing the early follicular, peri-ovulatory, and mid-luteal phases. Where possible, the findings will be combined in a meta-analysis. The review will also consider differences in exercise protocols, participant characteristics, such as the training level, and methods used to identify menstrual cycle phases.
