Cardiorespiratory Fitness and Performance Adaptations to High-Intensity Interval Training: Are There Differences Between Men and Women? A Systematic Review with Meta-Analyses.

Background: It is important to consider biological sex as a variable that might influence exercise adaptation in order to optimize exercise prescription for men and women.

Objective: The aim of this study was to quantify the impact of biological sex on maximal oxygen uptake ([Formula: see text]O) and performance outcomes after high-intensity interval training (HIIT).

Methods: A systematic search and review was conducted by two independent reviewers up to 8 September 2022 using MEDLINE, SPORTDiscus, and Sports Medicine & Education Index in ProQuest.
