Background:

Musculoskeletal injuries are the most common complaint in active populations. More than 50% of all injuries in sports can be classified as sprains, strains, ruptures, or breaks of musculoskeletal tissues. Nutritional and/or exercise interventions that increase collagen synthesis and strengthen these tissues could have an important effect on injury rates.

Objective:

This study was designed to determine whether gelatin supplementation could increase collagen synthesis.

Design:

Eight healthy male subjects completed a randomized, double-blinded, crossover-design study in which they consumed either 5 or 15 g of vitamin C–enriched gelatin or a placebo control. After the initial drink, blood was taken every 30 min to determine amino acid content in the blood. A larger blood sample was taken before and 1 h after consumption of gelatin for treatment of engineered ligaments. One hour after the initial supplement, the subjects completed 6 min of rope-skipping to stimulate collagen synthesis. This pattern of supplementation was repeated 3 times/d with ≥6 h between exercise bouts for 3 d. Blood was drawn before and 4, 24, 48, and 72 h after the first exercise bout for determination of amino-terminal propeptide of collagen I content.

Results:

Supplementation with increasing amounts of gelatin increased circulating glycine, proline, hydroxyproline, and hydroxylysine, peaking 1 h after the supplement was given. Engineered ligaments treated for 6 d with serum from samples collected before or 1 h after subjects consumed a placebo or 5 or 15 g gelatin showed increased collagen content and improved mechanics. Subjects who took 15 g gelatin 1 h before exercise showed double the amino-terminal propeptide of collagen I in their blood, indicating increased collagen synthesis.

Conclusion:

These data suggest that adding gelatin to an intermittent exercise program improves collagen synthesis and could play a beneficial role in injury prevention and tissue repair.

Varför "vitamin C–enriched gelatin"?

Ska bli intressant att se om de går vidare och jämför gelatin med något i träningssammanhang vanligt förekommande helt protein.

Har vi alltså hittat ett bruk för Pandy?

Är nyopererad sedan några veckor och kör 10 gram gelatinblad lösta i vatten + c-vitamin två ggr om dagen. Intressant att se att det faktiskt finns studier som ev. backar upp experimentet.

8 Oct 2015– Whey, gelatin, and Vit C improve tendon collagen protein synthesis
– 40 load cycles and 6h to recover is all your bone can handle to make collagen; intermittent load best! (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1474228/)
– Rapa use blocks protein’s effects in collagen protein synthesis
– Whey still useful for tendon repair!
