The object of this study was to determine the relationship of three measures of running velocity at lactate threshold (LT) with 10-km running velocity. The methods used to determine LT velocity (m.s(-1)) during submaximal treadmill running were: 1) LT(1), the velocity preceding two consecutive increases in blood lactate > or = 1 mmol.L(-1); 2) LT(D), the velocity associated with the maximum perpendicular distance between the nonlinear regression line and the straight line formed by the two end data points of the blood lactate profile; and 3) LT(4), the velocity corresponding to a blood lactate concentration of 4 mmol.L(-1).
