CLINICAL STUDIES ON COLLAGEN FOR SPORT HEALTH
CONCLUSION: Collagen hydrolysate ingestion inhibits bone collagen breakdown
The first clinical investigation of the effects of calcitonin (a drug used to treat disorders of bone metabolism, such as osteoporosis) alone or in combination with a collagen hydrolysate-rich diet on bone metabolism suggested that a daily ingestion of 10g of collagen hydrolysate plus calcitonin twice a week for 24 weeks had a greater effect in inhibiting bone collagen breakdown than calcitonin alone, as characterized by a fall in levels of urinary pyrinoline cross-links . Moreover, oral administration of collagen hydrolysate enhanced and prolonged the effect of calcitonin .
CONCLUSION: Collagen hydrolysate consumption can reduce parameter that have a negative impact on athletic performance
Research on the effectiveness of collagen hydrolysate in athletes with activity-related joint pain has also been performed. In a 24-week study conducted in 2008, 147 subjects who compete as part of a varsity team or club sport were recruited and randomly assigned to two groups: one group received a liquid with 10g of collagen hydrolysate, and the other received a placebo. Six parameters showed statistically significant changes with the dietary joint pain supplement collagen hydrolysate as compared with the placebo. The results of this study have implications for the use of collagen hydrolysate to support joint health and possibly reduce the risk of joint deterioration in a high-risk group. Despite the study’s size and limitations, the results suggest that athletes consuming collagen hydrolysate can reduce parameters that have a negative impact on athletic performance .
