Exercise increases the level of plasma orexin A in humans
Bibliographic record
Abstract
BACKGROUND: The purpose of this research was to study the effects of exercise on the concentration of plasma orexin A, a peptide regulating several physiological functions. METHODS: Blood samples were collected from participants (men, n=10; age: 24.4±2.93 years) 15, 0 min before the start of exercise, and 30, 45, 60 min after a cycle ergometer exercise at 75 W for 15 min. Also heart rate (HR), galvanic skin response (GSR), and rectal temperature were monitored. RESULTS: The exercise induced a significant increase (p<0.01) in plasmatic orexin A with a peak at 30 min after the exercise bout, in association with an increase of the other three monitored variables: HR (p<0.01), GSR (p<0.05), and rectal temperature (p<0.01). CONCLUSIONS: Our findings indicate that plasmatic orexin A is involved in the reaction to physical activity.

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.
