Researchers in Germany have published new study results suggesting collagen peptides may help reduce discomfort in athletes with functional knee problems. Subjects consuming the bioactive collagen peptides demonstrated statistically significant improvements in activity-related pain intensity, as well as reduction in the use of additional treatment options.
Writing in Applied Physiology, Nutrition, and Metabolism, researchers studied 139 adult ahtletes who consumed either 5 g of collage peptides or a placebo per day for 12 weeks. Researchers assessed the effect of the supplementation by measuring change in pain intensity during activity using a visual analogue scale, as well as pain intensity under resting conditions, range of motion (ROM) of the knee joint, and use of additional therapeutic options.
Statistically significant changes were observed in the collagen group for improvements to activity-related pain intensity and reductions to the use of additional therapeutic treatment options, compared to the placebo group. Pain under resting conditions also improved in the experimental group, although the effect was not significant compared to placebo. No significant changes to joint mobility were found.
“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 paint,” researchers concluded.
