Abstract
Since the 1950s there has been a steady accumulation of data from observational studies and clinical trials identifying a lack of physical activity, either in the industrial or leisure setting, as an independent major risk factor for coronary artery disease, with a similar relative risk as smoking, hypercholesterolemia and hypertension. More recently, poor cardiorespiratory fitness has also been shown to increase the risk of cardiovascular mortality significantly. Regular exercise is now known to have beneficial effects on peripheral and central circulation, skeletal muscle and myocardium, as well as lipid and carbohydrate metabolism. Individuals who become active in later life, for example, by way of a moderate intensity walking program, and who make only modest gains in fitness, nevertheless share in many of these health benefits and reduce their coronary artery disease risk. It is estimated that 60% of Canadians are physically inactive, a higher prevalence than for the other major risk factors. Consequently, efforts to encourage a more active lifestyle can have a significant impact on cardiovascular morbidity and mortality, with a marked reduction in costs to the health care system.

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.
