Moderate and heavy oxygen uptake kinetics in postmenopausal women
Bibliographic record
Abstract
The lack of estrogen in postmenopausal women not using hormone replacement therapy (HRT), compared with those using HRT, may reduce submaximal blood flow during exercise and result in an oxygen delivery limitation constraining oxygen uptake (VO(2) have been changed to V in the abstract, but will appear correctly in the body of the paper.) kinetics. The adaptation of pulmonary VO(2) (VO(2p)) during the transition to exercise in older women was examined in this study. Thirty-one healthy postmenopausal women (mean age, 61 +/- 6 years), 15 not using HRT and 16 using HRT, performed repeated exercise transitions (6 min) on a cycle, to work rates corresponding to 80% of estimated ventilatory threshold (moderate-intensity exercise) and to Delta50 (heavy-intensity exercise). There was no difference in moderate-intensity tauVO(2p) between non-HRT (40 +/- 9 s) and HRT (41 +/- 9 s) women. Similarly, there was no difference in heavy-intensity tauVO(2p) between non-HRT (44 +/- 8 s) and HRT (45 +/- 8 s) women. Thus, HRT did not affect the slowing of VO(2) kinetics of older women.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
