Improvement of activity-related knee joint discomfort following supplementation of specific collagen peptides
Bibliographic record
Abstract
The aim of the study was to evaluate the use of specific collagen peptides in reducing pain in athletes with functional knee problems during sport. Athletic subjects (n = 139) with functional knee pain ingested 5 g of bioactive collagen peptides (BCP) or a placebo per day for 12 weeks. The primary outcome of the study was a change in pain intensity during activity, which was evaluated by the participants and the attending physicians using a visual analogue scale (VAS). As secondary endpoints, pain intensity under resting conditions, the range of motion of the knee joint, and the use of additional therapeutic options were assessed. The results revealed a statistically significant improvement in activity-related pain intensity in the verum group compared with placebo. (ΔVAS BCP = 19.5 ± 2.4; ΔVAS Placebo = 13.9 ± 2.1; p = 0.046). The results were confirmed by the physician’s assessment. (ΔVAS BCP = 16.7 ± 1.8; ΔVAS Placebo = 12.2 ± 1.8; p = 0.021). Pain under resting conditions was also improved, but no significance compared with placebo was detected (ΔVAS BCP = 10.2 ± 18.4; ΔVAS Placebo = 7.4 ± 15.2; p = 0.209). Due to the high joint mobility at baseline, no significant changes of this parameter could be detected. The use of additional treatment options was significantly reduced after BCP intake. The study demonstrated that the supplementation of specific collagen peptides in young adults with functional knee problems led to a statistically significant improvement of activity-related joint pain.

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.
