Sandbakk and Solli 2022, sex differences in VO2max and endurance performance

Review of sex differences in VO2max and their effect on endurance performance. A roughly 10–12% performance gap persists across distance events, driven mainly by higher haemoglobin, larger heart and lower body-fat in men, which raise VO2max even when expressed per kilogram. Moderate as a narrative review of a consistent body of work.
