Discussion This is the first study to compare the effects

of ingesting supplements of protein and hydrolyzed protein on physical endurance performance. The results show that, with the current protocol, there was no mean effect on 5-min mean-power performance of ingesting the marine hydrolyzed protein-supplement Nutripeptin™ (Np) together with protein and carbohydrate during the preceding 120 min of submaximal cycling. Importantly, however, ingestion of the NpPROCHO-beverage resulted in an interesting correlation between performance in the 5-min mean-power test and athletic performance level

measured as a performance factor calculated from Wmax, VO2max and familiarization test 5-min mean-power performance. Although there are unavoidable uncertainties associated with analyzing data from a limited number of biological replicates, the confidence interval why analysis suggested a high level of credibility. The data thus indicates that for cyclists with a lower performance level, herein those showing VO2max values in the lower part of the participant cohort (decreasing towards 60 ml·kg-1·min-1), the Np-supplement may have had an ergogenic effect on 5-min mean-power performance compared to CHO alone. Indeed, when the cyclists were divided into two equally sized groups based on athletic performance level, NpPROCHO improved 5-min mean-power output-performance relative to CHO in the lesser performing athletes but not in the superior performing athletes. The ergogenic effect in the lesser performing cyclists was associated with a large effect size.
