The MO2 values for exhaustively exercised crabs in water medium or air medium are nearly twice the values found for pre-exercised crabs. The l-lactate concentration in the haemolymph increases from 0,75 � 0,37mmol to 9,63 � 2,1 mmol in P. warreni after air exercise, a value similar to those for other terrestrial and aquatic crabs. The same increase in the l-lactate concentration was found for water-exercised crabs.
