HR = heart rate; La = blood lactate; RS = running speed; RS2.5, RS3.0, RS3.5 and RS4.0 = submaximal running speeds corresponding to fixed blood lactate concentrations of 2.5, 3.0, 3.5 and 4.0 mmol·L-1 respectively
** denote significant difference from trained subjects at p < 0.01
*** denote significant difference from trained subjects at p < 0.001 respectively.
