Research Supports Cyclist Benefits From PeptoPro(R)

Recent studies in the USA have revealed that cyclists who consumed beverages enriched with PeptoPro® during time trials clocked faster times and had reduced muscle soreness post-activity compared with those drinking traditional, carbohydrate-only sports drinks. This study once again highlights the advantages of this innovative protein-hydrolysate from DSM Food Specialties in sports applications.

Conducted in the Human Performance Laboratory at James Madison University, Virginia, USA, subjects completed two 60 kilometer (km) cycling time trials. Each trial consisted of three simulated laps of a 20 km cycling loop, a 407 meter vertical climb, followed by a final five km climb. Throughout the trial, participants consumed 200 ml of a sports beverage, either PeptoPro enriched (CHO+PRO) or carbohydrate-only (CHO) every five km, plus an additional 500ml immediately after completion.

“We are delighted with the outcome of this trial.” comments Stefan Siebrecht, Business Development Director, PeptoPro. “As consumers increasingly value scientific evidence to support health claims, this study shows our commitment to demonstrating the effectiveness of PeptoPro and meeting these demands.

Offering tangible benefits which really matter to the athlete, PeptoPro is a strong proposition for manufacturers looking to create the ultimate sports drink.”

Performance times for the entire trial, the last 20 km loop and the final five km climb were recorded. Results indicated that over the 60 km time trial, cyclists who consumed the drink containing PeptoPro (CHO+PRO) rode, on average, 49 seconds faster compared to their counterparts drinking the carbohydrate-only beverage. All differences in performance between the two sets of cyclists occurred over the final 20 km, with the majority present in the final five km.
Analysis revealed that athletes drinking PeptoPro rode 3% faster and produced 5% more power during the final kilometres of the race – a significant advantage for athletes looking to gain a competitive edge.

In addition to testing performance times, plasma creatine phosphokinase (CK) and muscle soreness ratings were monitored before and after activity. Researchers again concluded that the beverage containing PeptoPro offered benefits to the cyclists by preventing significant increases in post-exercise CK and muscle soreness.

PeptoPro from DSM Food Specialties is a peptide based on natural milk protein. Due to its small size (chains of di- and tri-peptides), it can be fully and rapidly absorbed by the body without adversely affecting the digestive system. Its amino acids are therefore made available to the muscles considerably faster than if conventional sources of protein are consumed.
