At exercise intensities of 25, 45, 65 and 85% VO2peak, no sex-based differences in free fatty acid oxidation during exercise were observed.
“At various exercise intensities (25, 45, 65 and 85% VO 2 peak ), no sex-based differences in FFA oxidation during exercise were observed (Burguera et al. 2000;Romijn et al. 2000).”

The Abstract reports exercise at 45% of peak oxygen consumption, and Exercise responses reports no significant sex difference in systemic respiratory quotient during exercise. The paper does not establish the claimed result at 25%, 65%, or 85% VO2peak, and its direct FFA measurements concern uptake and release rather than oxidation.

“Similarly, in women, the ovarian hormones alter substrate partitioning in favor of greater fat utilization at any given relative exercise intensity (8,24) and may suppress hepatic glucose production (10) compared with men.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-11.
Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-11.
Cited sources are checked by gpt-6-sol.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
