The effects of a pre-exercise feeding with or without fungal carbohydrases (Carbogen) on blood parameters and exercise performance in elite cyclists: a preliminary study.

The effect of fungal carbohydrases (Carbogen[C]) consumed with a meal replacement bar (MBR) on glucose metabolism and exercise performance was determined in 5 male competitive cyclists. After a 12-hour fast, subjects performed two 60-min cycling bouts at 80% VO2max followed by a time-to-exhaustion (TE) ride at 100% VO2max. One hour prior to each cycling bout, subjects ingested a MRB + 160-mg C or 160-mg CaCO3 placebo (PL) in a double-blind, counterbalanced fashion.
