Collagen Peptide Supplement Shown To Improve Chronic Ankle Instability
Chronic ankle instability is a condition characterized by a
recurring giving way of the outer (lateral) side of the ankle. This condition
often develops after repeated ankle sprains. According to a recent study,
supplementation with collagen peptide may help improve ankle stability in
people with chronic ankle instability.
Fifty male and female athletes with chronic ankle instability
participated in the study. The participants were given 5 grams of collagen
peptide supplement or a placebo daily for six months. The Cumberland Ankle
Instability Tool and the German version of the Foot and Ankle Ability Measure
were used to measure the subjective perceived function of the ankle. Mechanical
stability was assessed by measuring ankle stiffness with an ankle arthrometer.
Participants in the supplement group had improvements in
subjective ankle stability compared to the placebo group. They also had
significant improvements in ankle stability function. A three month follow up
showed a significant decline in the number of ankle joint injuries in the
supplement group compared to the placebo group.
The study was conducted by researchers from the University of
Freiburg. It was presented at The International Society of Sports Nutrition
conference held the week of June 13, 2019.
