OBLA

OBLA – onset of blood lactate accumulation

• there is a certain point at which the aerobic system cannot supply energy quickly enough and our body has to switch to anaerobic processes.

• OBLA is the point during progressive exercise when blood lactate concentration suddenly increases.

• During aerobic work the blood lactate level is 1-2mmol per litre of blood.

• As intensity increases blood lactate increases.

• Above 4mmol there is a rapid increase in blood lactate. This is the anaerobic threshold (OBLA) point

• The OBLA depends on the aerobic fitness of the performer. in an untrained individual this…
