The

level above which aerobic
energy
production is supplemented by anaerobic mechanisms during
exercise
, resulting in a sustained increase in
lactate
concentration
and metabolic
acidosis
. The
anaerobic threshold
is affected by factors that modify
oxygen
delivery to the
tissues
; it is low in
patients
with heart
disease
.
Methods
of measurement include direct measure of
lactate
concentration
, direct measurement of bicarbonate
concentration
, and gas exchange
measurements.
