Role of Lactic Acidosis in the Ventilatory Response to Heavy Exercise
Bibliographic record
Abstract
The purpose of this study was to determine the role of lactic acidosis in the ventilatory response to heavy exercise above anaerobic threshold. Seven subjects ingested either NaHCO3 or CaCO3 at a dose of 300 mg/kg body weight and ran on a motor-driven treadmill at a work load corresponding to 90% of VO2max and above anaerobic threshold for a period of 5 min while minute ventilation and PETCO2 were recorded breath by breath. A total of 10 runs, 5 with CaCO3 and 5 with NaHCO3 in a randomized and blind order, were done in each subject. Statistical analyses of the effects of the chemicals on minute ventilation during the 15 s between min 4.75 and 5 of exercise showed that the differences in ventilation did not reach statistical significance (p greater than 0.05) in 5 of the 7 subjects. Venous pH measurements at the end of exercise revealed a significant increase with NaHCO3 (p much less than 0.05). It is concluded that lactic acidosis is not an essential determinant of ventilatory response to heavy exercise above anaerobic threshold in the majority of the subjects.

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.
