Hydrolysed Collagen Supplementation Enhances Patellar Tendon Adaptations to 12 Weeks' Resistance Training in Middle-Aged Men.

ABSTRACT: Resistance exercise (RE) with hydrolysed collagen (HC) supplementation increases collagen synthesis in young and middle-aged populations, and further enhances tendon adaptations to chronic RE in young athletes. However, it is unknown if middle-aged tendon can benefit from chronic RE with HC supplementation. We investigated the effects of 12-weeks' RE, combined with HC supplementation, on changes in patellar tendon (PT) properties in middle-aged men. In a double-blind design, 20 recreationally active men (age, 47 ± 5 years) were randomly assigned to a placebo (PLA, n = 11) or collagen (COL, n = 9) group. Both cohorts completed progressive lower-limb RE twice weekly for 12 weeks and were supplemented post-RE with COL (30 g HC and 50 mg vitamin C) or PLA (30.5 g maltodextrin and 50 mg vitamin
