Sampling sports during adolescence, exercise behaviour in adulthood, and the mediating role of perceived variety in exercise
Bibliographic record
Abstract
Objective: Physical activity levels decline from adolescence to adulthood, but participation in a variety of sports during childhood and adolescence (i.e., sampling) may increase physical activity behaviour during adulthood. We examined the association between sampling sports during adolescence and moderate-vigorous exercise behaviour in adulthood, and we assessed whether this relationship is mediated by perceived variety in exercise. Design: Study 1- prospective longitudinal; Study 2- cross-sectional. Our main outcome was exercise behaviour. Results: In study 1 (n = 775), sampling more sports during adolescence (b = .25, p < .01; 95% CI [.12, .39]) predicted increased frequency of exercise behaviour in young adulthood. In study 2 (n = 108), sampling more sports in adolescence (β = .08, p = .03; 95% CI [.03, .17]) was indirectly associated with exercise behaviour in adulthood through perceived variety in exercise. Conclusion: These findings add to the evidence that sampling sports during adolescence is positively associated with moderate-vigorous exercise during adulthood, and the experience of variety may, in part, explain this relationship. This research generates new hypotheses regarding a potential psycho-social mediator (perceived variety in exercise) of the sampling-exercise behaviour relationship.

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.
