Effects of specific collagen peptide supplementation combined with resistance training on Achilles tendon properties
What it found
Collagen peptides plus loading increased Achilles tendon cross-sectional area more than placebo (+11.0% vs +4.7%); this measures tendon structure, not clinical tendinopathy pain.
