A study published in the British Journal of Nutrition shows that consuming collagen peptides in combination with resistance training may help fight sarcopenia.
A steady loss of lean muscle mass along with fat mass increase, a condition known as sarcopenia, is one of the hallmarks of aging and means a loss of strength and mobility.
In a double-blind, placebo controlled study, the researchers investigated the effects of collagen peptides on the body composition and muscle strength of 60 men, aged 65 and older, with sarcopenia. The participants were divided into two groups. During the 12 weeks of the study, both groups underwent the same guided resistance training program, with three sessions per week. One group was daily supplemented with placebo, the other with collagen peptides (BodyBalance by Gelita): 15 g given in powder form dissolved in 250 mL water. The participants drank the solution within one hour after the training.
The researchers found that the collagen peptides further increased the benefits of the resistance training in elderly people with sarcopenia. Compared with placebo, participants in the collagen-supplemented group showed a significant increase in fat-free mass and muscle strength, as well as a statistically significant reduction in fat mass.
