Abstract
Low back pain is one of the leading causes of disability, absenteeism and a major contributor to medical expenses in industrialized countries. Physical activity ranging in intensity, frequency, duration and type, has become a commonly used intervention for ameliorating/eliminating low back disorders. To date, no specific exercise intervention has been shown to be substantially more effective than another. A higher level of physical activity participation may help to lower the incidence of low back pain. However, this is not necessarily the case and an alternative theory is that the relationship between back pain and the level of physical activity follows a U-shaped curve, i.e. that too little or too much activity is equally detrimental to back health. Several researchers have demonstrated that muscular endurance and not muscular strength is more protective when it comes to the low back. Emphasis should be placed on the co-contraction of the back extensors and abdominals through isometric stabilization exercises. There is also considerable evidence that general aerobic exercise such as walking plays a key role in both preventing and treating low back injuries.

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.
