Summary

Previous work has shown that gelatin supplementation could increase collagen synthesis in humans. In this study subjects consume placebo, 5 or 15 g of gelatin with a standard amount of vitamin C (48 mg) 1 hour before 6 minutes of jump rope exercise. The feeding and exercise intervention was repeated every 6 hours while the subjects were awake for three days and the amount of the amino terminal procollagen I peptide (PINP) was determined; a marker of collagen synthesis, in the blood. Consistent with the hypothesis that gelatin increases collagen synthesis in humans; the amount of PINP in the 15 g gelatin group was significantly higher than either the placebo or the 5 g groups. These data conclusively demonstrate that gelatin supplementation can increase exercise-induced collagen synthesis in humans. Hydrolyzed collagen has a similar amino acid profile, in particular with high concentrations of glycine, proline, hydroxyproline, and arginine. Thus, the current study aims to determine is the same dose of gelatin, hydrolyzed collagen and a gelatin/collagen mix, all with a standard dose of vitamin C effect PINP levels similarly.

gelatin, collagen, gummy dose

The study is aimed at determining if the same dose of gelatin, hydrolyzed collagen (administered in a beverage form) or a mixture gelatin/hydrolyzed collagen (administered in a gummy form) with a standard dose of vitamin C (50 mg) has a similar effect a marker of collagen synthesis (PINP). In a randomized, crossover design subjects consume 3 different nutritional supplements: (a) 15 of gelatin, (b) 15 hydrolyzed collagen (administered in a beverage form) or (c) 15 g of gelatin/hydrolyzed collagen mixture all with a standard dose of vitamin C (50 mg) 1 hour prior to exercise stimulus (6 minutes of jump rope). A baseline assessment with only the jump rope and no intervention will also be conducted prior to the interventions. Each intervention will be separated by a \>24 hr washout. Following completion of exercise, subjects will remain in the lab in a rested state for the subsequent 4 hours. After 4 hours blood samples will be collected. Blood samples will be used for PINP analysis.
