AB  - 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(-1)of 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 < 0.001) and CHO-PRO-PEP (p < 0.001). 
      Additionally, mean heart rate for the CHO condition was significantly lower than 
      that for CHO-PRO (p = 0.021). Time-to-complete the 5 km TT was not significantly 
      different between conditions (m +/- SD: 456 +/- 16, 456 +/- 18 and 455 +/- 21 sec for 
      CHO, CHO-PRO and CHO-PRO-PEP respectively, p = 0.98). Although the addition of 
      hydrolyzed marine peptides appeared to influence metabolism during endurance 
      exercise in the current study, it did not provide an ergogenic benefit as 
      assessed by 5 km TT performance.
