Table 3 Lactate, blood glucose and Blood Urea Nitrogen (BUN) concentrations in venous blood previous to, during and after 120-min of submaximal cycling at 50% of maximal aerobic power with ingestion of either carbohydrate (CHO), protein + carbohydrate (PROCHO) or Nutripeptin™ + protein + carbohydrate (NpPROCHO).

From: Improved cycling performance with ingestion of hydrolyzed marine protein depends on performance level

  1. Asterixes (*, ** and ***) denote changes in concentrations that occur during the time-course of each particular subset of prolonged cycling (compared to baseline set to 0%). * = P < 0.017, ** = P < 0.003, *** = P < 0.0003. Letters (a and b) denote differences in concentrations that occur between subsets of prolonged cycling. N = 12
