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.

Design
Randomized controlled trial
Year
2022
Sample size
40
Population
healthy young men, no diagnosed tendinopathy
Intervention
5 g/day specific collagen peptides vs placebo, with 14 weeks of resistance training
Outcome
Achilles tendon cross-sectional area, stiffness, strength
