Collagen Peptides for Sports Nutrition,
Backed by Science
Nutrition plays a key role as athletes’ prepare to reach optimum performance levels and the essential role of proteins is also well known to recreational athletes and active consumers. Proteins deliver numerous health benefits and specific bioactive proteins, collagen peptides in particular, can offer benefits beyond muscle building. These include improving athletic performance, protecting connective tissues, supporting healthy joint maintenance and helping to reduce the risk of injury.
Collagen peptides deliver numerous health and nutritional benefits to athletes both during and after exercise.
Collagenx hydrolysed collagen contains 18 amino acids, the building blocks of our tissues and the primary component of proteins. Glycine, proline and hydroxyproline represent around 50% of Collagenx hydrolysed collagen total amino acid content; the glycine and proline concentration in our hydrolysed collagen is 10 to 20 times higher than in other proteins. As a result, Collagenx hydrolysed collagen offers health benefits that cannot be found in other protein sources.
A recent double-blind, randomised, placebo-controlled clinical study published in the journal "Amino Acids"2 performed with Newcastle University in the UK demonstrated that the subjects who were supplemented with CollagenX hydrolysed collagen experienced
- 20% less muscle soreness at all time points after intense exercise, compared with those who received a placebo dose
- An increase in sports performance. Performance was maintained at 24h post exercise and increased at 48h post exercise. Meanwhile, the performance of the placebo group progressively declined.
Restoring Protein Content of Muscles
During and after long periods of exercise, protein loss can occur in the muscles as their structural integrity is compromised by oxidation, membrane microlesions and inflammatory reactions. A high protein sports nutrition diet just after exercise may enhance muscle anabolism, replacing lost proteins and helping to maintain and restore the protein content of the muscles.
Aiding Muscular Contraction
Muscular function is dependent on the energy produced by the breakdown of a compound called adenosine triphosphate (ATP) in cells. Creatine is a molecule consisting of three amino acids – glycine, arginine and methionine – that can aid muscular contraction during periods of high intensity exercise and also helps to replace depleted ATP levels. Collagenx hydrolysed collagen, which consists of 20% glycine and 8% arginine, can support the synthesis of creatine in the body to improve performance during short bursts of exercise and help athletes to increase their body mass.3
Providing Energy for Performance
Oral arginine supplements may also have a beneficial effect on athletic performance, even at a low dose.4 A daily recommended dose of 10g of Collagenx hydrolysed collagen produces almost 1g of arginine per day. A study showed that by ingesting 1g supplements of arginine and ornithine taken five days per week for five weeks for sports nutrition can increase strength.5 Studies suggest that arginine stimulates the release of growth hormone from the pituitary gland, which may explain performance improvement6.
Supporting Connective Tissues and Preventing Injuries
Collagenx hydrolysed collagen can support joint health by regenerating cartilage and reducing joint inflammation, as demonstrated in a recent in-vivo study7. Collagenx hydrolysed collagen can increase the production of cartilage matrix, aggrecan and type II collagen8. An in vivo study also demonstrated a significant increase in collagen fibril diameter of the Achilles tendon after collagen peptides supplementation for 8 weeks9.
In a large-scale study of different categories of athletes, those taking a mix of collagen peptides, BCAA and arginine over a period of two years experienced a decreased tendon, ligament, joint and muscle injury rate10.
Collagen peptides may help protect the joint matrix and help to reduce joint discomfort11. A clinical study has shown that Collagenx hydrolysed collagen can help reduce joint stiffness12. A smaller, placebo controlled study13 confirmed that consuming a collagen supplement with vitamin C, followed by a burst of intensive exercise, can help build ligaments, tendons and bones, and likely play a beneficial role in injury prevention and tissue repair. Additional clinical evidence for injury prevention are reported on athletes by Baar, 201514, and Ribas-Fernandez, 199815.
Weight Management with Sports Nutrition
Known to be among the most satiating macronutrients, proteins can prevent cravings and help people reach their fitness and weight goals. Collagenx hydrolysed collagen collagen peptides are particularly renowned for their ability to help individuals lose or maintain weight when incorporated in weight management formulations. An in vivo study conducted in 2006 by the Laboratory of Physiology and Ingestive Behavior, INRA-AgroParis Tech (Paris, France), showed that Collagenx hydrolysed collagen is more effective than a standard dairy protein in weight management.
A 2009 study demonstrated the improved satiating effect of collagen peptides on humans, in comparison to other proteins. 16
