A 5 min bout of exhaustive exercise in 2-3 g rainbow trout resulted in a 2.0-2.5 fold increase in oxygen consumption (MO2), a 5-fold increase in whole-body lactate (LAC) levels and a near depletion in whole-body glycogen (GLY), ATP and creatine phosphate (CP) stores; glucose, ADP and AMP did not change. Recovery of MO2 and LAC was complete by 6 h, by which time GLY had stabilized at about 65% resting levels without further recovery through 24 h. Complete recovery of ATP required 1.0-1.5 h… CONTINUE READING
