Lactate accumulation during exercise - the influence of body fluid shifts
Castleman., Barbara, Ann
During graded exercise, an intensity is reached where a subjects ability to remove lactate lags behind the rate of lactate production. The influence of body fluid shifts, during exercise of increasing intensity, on the pattern of the blood lactate response was studied. The maximal oxygen uptake (V02 max) was measured using a treadmill, on eleven subjects. Subsequently, lactate accumulation in venous blood was measured, in triplicate, up to an oxygen consumption greater than 90% V02max. During all exercise, oxygen consumption was measured using an online system. In addition, the blood samples at each workload were used to determine haematocrit (Hct) and haemoglobin (Hb) levels.
