Organized sport and physical activity participation and free play in children and youth: A test of the over-scheduling hypothesis using longitudinal data
Bibliographic record
Abstract
The relationship between organized sport participation and positive youth development is well established in current literature. However, too much involvement in sport has been identified as having a potentially negative impact. Over-scheduling and its impact on free play is one concern, given the importance of the latter to overall health and development. At present, it is not known if higher participation in organized sport has a positive or negative effect on discretionary play in youth. The Physical Health and Activity Study Team (PHAST) study is a six-year, longitudinal cohort study investigating organized and discretionary physical activity, motor competence, aerobic fitness and anthropometry in 2278 consented fourth grade children (ages 9 to 10) enrolled in public school in Southern Ontario. Using mixed effects modeling, we found that higher participation in organized sport was associated with increased participation in free play over time (Coef = 0.16, p

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.
