Popis: | Background The purpose of this study was to examine the efficacy of introducing a fish protein hydrolysate (PEP) concurrently with carbohydrate (CHO) and whey protein (PRO) on endurance exercise metabolism and performance. Methods In a randomised, double blind crossover design, 12 male volunteers completed an initial familiarisation followed by three experimental trials. The trials consisted of a 90 min cycle task corresponding to 50% of predetermined maximum power output, followed by a 5 km time trial (TT). At 15 min intervals during the 90 min cycle task, participants consumed 180 ml of CHO (67 g.hr-1 of maltodextrin), CHO-PRO (53.1 g.hr of CHO, 13.6 g.hr-1 of whey protein) or CHO-PRO-PEP (53.1 g.hr-1 of CHO, 11 g.hr-1 of whey protein and 2.4 g.hr-1of hydrolyzed marine peptides). Results and conclusions During the 90 min cycle task, the respiratory exchange ratio (RER) in the CHO-PRO condition was significantly higher than CHO (p |
