Abstract
Objectives: The aim of this study was to assess the associations of muscle-strengthening exercise (MSE) with academic performance (AP) of different subjects in Chinese school-aged children and adolescents. Methods: Cross-sectional data on 67,281 students were included. Engagement in MSE was assessed using a specific question, and AP was assessed through self-reported grade in Literacy (Chinese), Mathematics, and Language (English). The analysis explored the associations between days of engagement in MSE and AP in Chinese, Mathematics, and English, separately. Results were presented as odds ratios (ORs). Results: There was a generally progressive increase in the likelihood of better AP of Chinese, Mathematics and English with increase in days of MSE. Specifically, one day of MSE per week was associated with an 11 % increase of better AP in Chinese, with a gradual increase up to 4 days per week (OR = 1.42), peaking at 6 days. The odds of enhanced AP related to Mathematics increased with days of MSE, starting with a 9 % increase for 1 day per week (OR = 1.09), and reaching a 39 % increase at 4 days per week. The odds of improved AP in English were 9 % higher for 1 day per week of MSE and continued to a 31 % increase for 4 days per week. Conclusion: This study suggests the potential positive role of MSE in enhancing AP in children and adolescents. Future studies are needed to confirm our findings based on longitudinal or intervention studies.

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
