Abstract
This study examined the unique contribution of acute exercise to perceptions of pain in 32 older, overweight, or obese adults with knee osteoarthritis (OA), statistically controlling for the effect of diurnal variation, supplemental medication intake, and stress. Using an ecological momentary assessment method, 964 pain appraisals were recorded and coded into experience samplings that occurred either on a nonexercise day or before or following scheduled activity on an exercise day. Univariate and multivariate multilevel modeling analyses controlling for supplemental medication intake and stress revealed a quadratic trend in diurnal pain variations with the peak occurring mid-afternoon. Although pain was significantly elevated following exercise in comparison with the predicted diurnal pattern, pain reports later in the day following exercise were significantly lower than immediately following exercise. We conclude that the pain associated with acute exercise by older, overweight, or obese adults who have knee OA is transient. Findings are discussed in terms of the implications of exercise therapy for patients with knee OA.

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
