Abstract
OBJECTIVE: The prevalence of obesity and related comorbidities has dramatically increased in the pediatric population in recent years, and youth from ethnic minorities appear to be disproportionately affected. Although several factors play a role in these ethnic health disparities, evidence suggests fitness may also be an important mediator of disease risk in children. Therefore, the purpose of the present investigation was to compare aerobic fitness (VO2peak) in healthy Caucasian (C), African-American (AA), and Latino (L) youth and to evaluate differences after controlling for gender, maturational stage, and body composition. MEASURES: Seventy-three healthy boys and girls [C (n=18), AA (n=19), and L (n=36)] aged 7-14 years participated in the study. VO2peak was evaluated using an all-out, progressive treadmill protocol, total body composition was estimated via dual-energy x-ray absorptiometry, and ethnicity was determined via parental questionnaire. RESULTS: VO2peak relative to total body mass (mL/kg/min) was significantly lower in Latinos compared to either Caucasian or African-American children. Further, after controlling for gender, maturational stage, and body composition, L (1.68 +/- 0.05 L/min) and AA (1.57 +/- 0.05 L/min) youth had significantly lower VO2peak compared to C (1.84 +/- 0.04 L/ min; P<.05) children. CONCLUSION: These results suggest that Latino and African-American children have lower aerobic fitness levels than Caucasian children and this effect is independent of gender, maturation, and body composition.

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
