Abstract
This article looks retrospectively at lessons learned from the Trois-Rivières physical education study. A brief review of the experimental design shows 546 students assigned by class cohort to either an additional 5 hours of quality physical education per week in grades 1 through 6, or a control treatment (minimal physical education by the homeroom teacher). Strengths of the study include a quasi-experimental design, a prolonged and well-defined intervention, assessment of compensation for the program, continuation of observations into middle age, collection of data in urban and rural environments, consistency of teaching staff and technical personnel, documentation of changes in academic achievement, assessment of bone maturation, a carefully constructed database, and control for cross-contamination. Limitations include some secular change, limited information on pubertal stages, difficulty in generalizing findings to an English-speaking environment, and some rigidity in the statistical design. The study demonstrates that cardiorespiratory function, muscle strength, and field performance can all be enhanced in primary school with no negative impact on academic work. Further, attitudes, behavior, and function are favorably influenced in adults. Future studies should seek out stable populations, define interventions closely, contract with participants for a long-term follow-up, and assess the immediate and long-term impact on health and function. Above all, there is a need for a dedicated principal investigator who will devote his or her entire career to the longitudinal study.

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
