ABSTRACT:
The aim of this study was to assess the sensitivity of the lactate minimum speed test to changes in endurance fitness resulting from a 6 week training intervention. Sixteen participants (mean +/- s: age 23 +/- 4 years; body mass 69.7 +/- 9.1 kg) completed 6 weeks of endurance training. Another eight participants (age 23 +/- 4 years; body mass 72.7 =/- 12.5 kg) acted as non-training controls. Before and after the training intervention, all participants completed: (1) a standard multi-stage treadmill test for the assessment of VO2max, running speed at the lactate threshold and running speed at a reference blood lactate concentration of 3 mmol.l-1; and (2) the lactate minimum speed test, which involved two supramaximal exercise bouts and an 8 m in walking recovery period to increase blood lactate concentration before the completion of an incremental treadmill test. Additionally, a subgroup of eight participants from the training intervention completed a series of constant-speed runs for determination of running speed at the maximal lactate steady state. The test protocols were identical before and after the 6 week intervention. The control group showed no significant changes in VO2max, running speed at the lactate threshold, running speed at a blood lactate concentration of 3 mmol.1-1 or the lactate minimum speed. In the training group, there was a significant increase in VO2max (from 47.9 +/- 8.4 to 52.2 +/- 2.7 ml.kg-1.min-1), running speed at the maximal lactate steady state (from 13.3 +/- 1.7 to 13.9 +/- 1.6 km.h-1), running speed at the lactate thresholds (from 11.2 +/- 1.8 to 11.9 +/- 1/9 km.h-1) and running speed at a blood lactate concentration of 3 mmol.1-1 (from 12.5 +/- 2.2 to 13.2 +/- 2.1 km.h-1) (all P < 0.05). Despite these clear improvements in aerobic fitness, there was no significant difference in lactate minimum speed after the training intervention (from 11.0 +/- 0.7 to 10.9 +/- 1.7 km.h-1). The results demonstrate that the lactate minimum speed, when assessed using the same exercise protocol before and after 6 weeks of aerobic exercise training, is not sensitive to changes in endurance capacity.
