Collagen ingestion to stimulate skeletal muscle growth

CONSTRUCT (COllagen iNgeSTion foR mUscle Connective Tissue)

In this collaborative project between Maastricht University Medical Centre+ (MUMC+) and Gelita AG, firstly it will be determined what is the optimal ration between whey and collagen protein that should be ingested during recovery from exercise to provide ample essential amino acids without compromising post-prandial plasma glycine and proline availability. Secondly, one of the proposed combinations of whey and collagen protein drinks will be applied to determine post-prandial myofibrillar and collagen tissue protein synthesis rates in vivo in muscle at rest and during recovery from a single resistance type exercise session in healthy, young men.

This project contributes to the knowledge on the impact of food ingredients on muscle mass and metabolism in young adults. The novel information generated through the current projects enables true translation of findings that the combined ingestion of whey and collagen protein stimulate myofibrillar and collagen protein synthesis rates, both considered to be critical to muscle reconditioning. This work will impact the view on nutrition to support post-exercise muscle remodeling and may change the guidelines on sports nutrition to support post-exercise recovery.

Furthermore, it may provide new leads towards new nutritional concepts in terms of prevention; i.e., prevention of functional decline and loss of independence through maintenance of skeletal muscle strength and function with aging, thereby supporting ‘healthy aging’ of our society. Additionally, translation towards clinically compromised and/or institutionalised populations (i.e., supporting muscle rehabilitation within a clinical setting), represents another important application of the combined ingestion of whey plus collagen.

Deliverables :

1. definition of an optimal ratio of whey and collagen protein that should be ingested during post-exercise recovery to provide ample essential amino acids without compromising post-prandial plasma glycine and proline availability in vivo in humans.

2. Evidence to show that whey plus collagen protein ingestion increases both myofibrillar and collagen tissue protein synthesis rates in muscle tissue at rest and during recovery from exercise in vivo in humans.
