Alterations in lactate metabolism as a consequence of EIMD have not been reported consistently, with some studies
reporting no change in blood lactate ([La]) concentration during submaximal exercise and others reporting an
increase.
Elevated [La] responses may reflect an increased metabolic demand on undamaged fibers during exercise or that damage may occur to type II muscle fibers during eccentric exercise,resulting in an increased activation
of nondamaged type II fibers to enable the same level of force production. However, as is the case with the equivocal V_ O2 responses observed following muscle-damaging exercise, the different methods used to evoke symptoms of EIMD, and the subsequent endurance exercise adopted make comparisons between such studies problematic
