Abstract
PURPOSE To examine the efficacy of a ten-week physical activity program on the health-related components of physical fitness of children in grades 4 and 5. METHODS Twelve boys (10.3±0.57 yrs) and 16 girls (10.0±0.65 yrs) participated at least 3 days per week in a low organizational games program offered every day after school for 10 weeks. With supervision, the children walked 25 minutes to the one-hour physical activity program which emphasized inclusive and continuous participation rather than elimination or competition. Pre and post-program testing included assessments of cardiorespiratory endurance, muscular strength and endurance, flexibility, and body composition. Aerobic power and heart rate were directly assessed in a submaximal treadmill test that involved walking at 5 km.hr−1 with a 2% increase in grade every 2 minutes for up to 16 minutes. Following CSEP standardized protocols, muscular strength and endurance were assessed using push-ups and curl-ups and the sit and reach test was performed to measure flexibility. Body fat was assessed indirectly from the sum of eight skinfolds. RESULTS Indicative of improved cardiorespiratory endurance, submaximal exercising heart rate and recovery heart rate were lower during post-intervention testing, with significant differences (p < .05) noted at minutes 7, 9, and 11 of the treadmill test and 3 minutes of recovery. No significant changes were found in aerobic power. The number of curl-ups performed increased significantly (p = .000) from 11.6±9.5 to 16.6±12.1. The number of push-ups performed increased significantly (p = .000) from 7.7±5.7 to 11.6±6.5. Flexibility increased significantly (p = .000) from 256.3±58.0 mm to 287.9±58.4 mm. The average sum of skinfolds decreased significantly (p = 0.008) from150.6±61.3 mm to 142.3±59.9 mm. CONCLUSION The results from this study showed that children participating at least 3 times per week in a low organizational games program for 10 weeks significantly improved their cardiorespiratory endurance, muscular strength and endurance, and flexibility while decreasing their sum of skinfolds. *Supported by St. Francis Xavier University

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
