Abstract
Abstract Study aim : Maximal oxygen uptake (VO 2max ) is the greatest rate at which the body can use oxygen and is an indicator of aerobic power. Although aerobic fitness is such a valuable determinant of health, there is limited research with established normative values for a healthy young adult Canadian population. The purpose of the study was to develop normative reference values for a Canadian young-adult population. Material and methods : 550 undergraduate student (280 male and 270 female) participants, with a mean body mass (BM) of 72.08 ± 15.05 kg, mean age of 21.16 ± 1.26 years old and mean height of 171.95 ± 10.25 cm completed a VO 2max test using the Bruce treadmill protocol. Male and female classifications were established for the total exercise time in minutes and for the measured VO 2max using percentiles and a seven-category classification system. Results : There were statistically significant differences between the sexes for VO 2max values (p < 0.001). The measured assessment for the healthy young Canadian adults showed a mean VO 2max value of 40.90 ± 7.50 mL/kg/min for females and 49.89 ± 9.20 mL/kg/min for males. Females were able to withstand the exercise protocol for a mean of 11.92 ± 1.97 minutes, while males exercised for an average of 14.33 ± 2.40 minutes before the test was terminated. Conclusions : This study provides specific normative values for the aerobic fitness of a university aged Canadian population which can be used as reference values for cardiovascular health and fitness assessments.

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
