Abstract

Introduction: The quantity and quality of collagen within a tendon determines its mechanical properties, which in turn plays a significant role on the function of the muscle that it is in series with. The aim of this study was to investigate whether nutritional supplementation with Minerva Collagen® supplements can improve muscle and tendon properties, and thereby improve physical performance in young, recreationally active adults. Methods: A total of 46 male and female participants (22.0 (SE 2.94) years) participated in this randomised double-blind placebo-controlled study. All participants received 12-weeks supplementation of either Active Gold Collagen® (4 g/day of fish hydrolysed collagen), ‘’Osteoarthritis’’ collagen (5 g/day of bovine hydrolysed collagen) or non-collagen placebo drink. Before and after supplementation, ultrasound scanning and dynamometry were used to assess Achilles tendon properties (stiffness, Young’s modulus and hysteresis) and muscle structure (size and fascicle architecture) and function (strength, electromechanical delay and rate of moment development). Results: Thirty-seven participants completed the intervention (Osteoarthritis product: n=13, Active Gold Collagen®: n=12, Placebo: n=12). For the completing participants, no significant changes were found within or interactions between any of the groups for any of the tendon or muscle parameters assessed (tendon stiffness group*time interaction P=0.62, tendon Young’s Modulus group*time interaction P=0.29, muscle strength group*time interaction P=0.36, RMD and EMD group*time interaction P= 0.20 and P=0.68 respectively). Conclusion: This study did not find any changes in the mechanical and functional properties of muscle and tendon in young, healthy and recreationally active individuals following 12 weeks of dietary collagen supplementation delivered without the implementation of a training intervention.
