The Cost Of Ethanol Synthesis During Recovery From Exhaustive Exercise In Grass Carp (Ctenopharyngodon Idella), Simon A. Bradford

Electronic Thesis and Dissertation Repository

Grass carp (Ctenopharyngodon idella) reduce white muscle glycogen (~14 µmol glucosyl units/g wet tissue) in response to exhaustive exercise. This reduction results in a small increase in muscle lactate (~9 µmol/g wet tissue) and a larger increase in muscle ethanol (~30 µmol/g wet tissue). Tissue-specific and whole-body measures of glycogen, ethanol and lactate confirm that ethanol is the major “anaerobic” glycolytic end-product. Additionally, while peak muscle and blood ethanol levels occur immediately post-exercise, the excretion of ethanol to the environment is delayed, occurring over a 30-minute period beginning ~105 minutes following exercise. As the total amount of ethanol …
