Abstract
To investigate splenic erythrocyte volume after exercise and the effect on hematocrit- and hemoglobin-based plasma volume equations, nine men cycled at an intensity of 60% maximal O(2) uptake for 5-, 10-, or 15-min duration, followed by an incremental ride to exhaustion. The reduction in spleen volume, calculated using (99m)Tc-labeled erythrocytes, was not significantly different among the three submaximal rides (5 min = 28%, 10 min = 30%, 15 min = 36%; P = 0.26). The incremental ride to exhaustion resulted in a 56% reduction in spleen volume, which recovered to baseline levels within 20 min. Plasma catecholamines were inversely related to spleen volume after exercise (r = 0.70-0.84; P < 0.0001). There were no differences in red cell or total blood volume pre- to postexercise; however, a significant reduction in plasma volume was observed (18.9%; P < 0.01). There was no difference between the iodinated albumin and the hematocrit and hemoglobin methods of assessing plasma volume changes. These results suggest that the spleen regulates its volume in response to an intensity-dependent signal, and plasma catecholamines appear partially responsible. Splenic release of erythrocytes has no effect on indirect measures of plasma volume.

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 it
