NCT05427279

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Collagen protein synthesis

    Collagen protein synthesis will be indirectly measured by measuring pro-collagen type I N-terminal propeptide (PINP) in the serum before and 4 hours after the last exercise bout (at 28 hours of the protocol)

    Baseline (0 hour) to 4 hours after last exercise bout (at 28 hour of the protocol)

Secondary Outcomes (2)

  • Ligament collagen content

    Baseline (0 hour) to directly after consumption of supplementation (1 hour)

  • Strength of engineered ligaments

    Baseline (0 hour) to directly after consumption of supplementation (1 hour)

Masking Details
A randomized double-blind crossover design with neither the subjects nor the investigators knowing who is on which treatment. The interventions will be coded using a blinded alphabetical letter code (A, B, C, D). A delegate researcher (independent party not further involved in the study) will randomize all interventions using a computer-generated randomization list. The delegate will hand in the code-breaker to the principal investigator in a sealed envelope. The envelope will be stored in a locked filing cabinet in the principal investigator's office, which will also be locked when unoccupied. The envelope will be opened by the principal investigator after completing the analysis of blood samples.

CROSSOVER
Model Details: Participants will consume a supplemental dose of hydrolyzed collagen (20g with 50mg vitamin C), PrimaColl (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 exercise bouts (6 minutes of jump rope). The type of consumed supplementation will be randomized where neither the participant nor investigator will know which supplement is being consumed. Each participant will repeat the protocol four times.
