The purpose of this study is to determine the effects of repeated dosing vitamin C enriched hydrolyzed collagen (HC) over a 24hr period, compared to PrimaColl™ (PC), whey protein (WP) and placebo (PL), with prescribed exercise on collagen synthesis. To achieve this, participants will consume a supplemental dose of HC (20g with 50mg vitamin C), PC (20g with 50mg vitamin C), whey protein (20g whey isolate with 50mg vitamin C) or a placebo (20g maltodextrin with 50mg vitamin C) 1hr prior to an exercise bout (6 minutes of jump rope), this will be repeated three times over a 24h period. The amount of collagen protein synthesized will be indirectly measured by measuring pro-collagen type I N-terminal propeptide (PINP) in the serum before and 4hrs after the last exercise bout.
