Abstract
The purpose of this study was to determine the reliability of short-term power output, heart rate (HR) response during and after a treadmill test, and time to complete a 25-m dash in healthy preschool children. Thirty-two 3- to 5-year-old boys and girls completed two sessions approximately one week apart. Intraclass correlation coefficient (ICC) and coefficient of variation (CV) were calculated to evaluate reliability. Power output was found to be reliable with ICCs ranging from 0.83 to 0.93 and CVs from 8.1 to 9.7%. Time to complete the 25-m dash was highly reliable (ICC = 0.91, CV = 3.7%). Reliability for HR at submaximal exercise (ICC = 0.28, CV = 18.8%) and HR recovery (ICC = 0.42, CV = 14.0%) was not as strong. These findings should assist in determining appropriate fitness tests for preschoolers.

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
