Reduced Oxygen Uptake During Steady State Exercise After 21-Day Mountain Climbing Expedition to 6,194 m
Bibliographic record
Abstract
We investigated the effect of a 21-day climbing expedition to 6,194 m on the oxygen uptake (V022) and leg blood flow (LBF) responses to submaximal exercise in five healthy, fit men during two-leg kicking exercise a 0-W and 50-W. Tests were completed 1 week before and 3 days after altitued acclimatization. The adaptation of VO2 at exercise onset was described by the time to 63% of the new steady state. Steady state VO2 during 50-W exercise was less post-climb (1290+/- 29 mL/min, mean +/- SE) than pre-climb (1413+/- 63 mL/min, P <.05). VO2 adapted more slowly at the onset of 50-W exercise post climb. There were no differences in the steady state LBF during the 50-W exercise, the increase above baseline, or the adaptation post-climb. Respiratory exchange ratio was greater at 50-W post-climb compared to pre-climb. Reduced steady state V02 during exercise after exposure to high altitude is consistent with an increase in metabolic efficiency.

How this classification was reachedexpand
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.
