Abstract

The purpose was to evaluate muscle deoxygenation (Δ[HHb]), oxygen uptake (VO2), ventilation (VE), and arterialized blood lactate [La-] throughout exhaustive incremental (RAMP) and severe-intensity exercise (SI) during follicular (FOL) and luteal (LUT) menstrual phases. During RAMP, Δ[HHb]/VO2 was 65% lower in LUT below gas exchange threshold (p0.05). During SI,Δ[HHb]/VO2 was 18% lower in LUT during the kinetic phase (p0.05). No FOL/LUT differences in RAMP-performance (FOL: 218 ± 35 W; LUT: 221 ± 29 W) or SI-endurance (FOL: 99 ± 20 s; LUT: 96 ± 15 s) (p>0.05) were found. These data demonstrate that physiological differences between menstrual phases exist, however, performance is unaffected.
