Incidence of exercise‐induced arterial hypoxemia in prepubescent females
Bibliographic record
Abstract
Due to the recent discovery of exercise-induced arterial hypoxemia (EIAH) in healthy active women with normal levels of peak oxygen uptake (V'(O(2)peak), this study examined the incidence of EIAH in prepubescent females. Nineteen healthy, active, prepubescent females (X +/- SD: age = 11.1 +/- 1.6 years; height = 145.8 +/- 9.1 cm; weight = 35.6 +/- 7.0 kg) performed a progressive maximal exercise test on an electronically braked cycle ergometer starting at 0 W and increasing power by 15 W. min(-1). During this test, expired gases, heart rate (HR), and percent arterial oxyhemoglobin saturation (%SaO(2)) were measured. Results for physiological variables at maximal exercise were as follows: V'(O(2)peak) = 43.7 +/- 7.0 ml x kg(-1) x min(-1); HR(max) = 199 +/- 5 beats x min(-1); %SaO(2) = 96.6 +/- 1.2%. For nearly all subjects, the %SaO(2) at maximal exercise was above levels that would reduce V'(O(2)peak). Therefore, in comparison to previous reports of EIAH in adult women with similar V'(O(2)peak), EIAH does not appear to occur in the prepubescent female population.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
