Plasma lactate and plasma volume recovery in adults and children following high-intensity exercises.

Aim: To compare plasma lactate concentration recovery kinetics when measured and corrected for variations in plasma volume between children and adults.

Methods: Nine boys (11.3 +/- 1.

Plasma lactate recovery from maximal exercise with correction for variations in plasma volume.

Background: To compare plasma lactate concentrations and plasma lactate kinetics during recovery, for measured and corrected values for changes in plasma volume, after a maximal aerobic exercise.

Methods: Sixteen male subjects performed an incremental and maximal exercise in order to reach maximal aerobic power. Prior to the exercise, at the end and during recovery (2, 5, 12 and 30 min), blood samples were collected through an antecubital catheter.
