The aim of the present study was to compare the anaerobic threshold and the maximal lactate steady state (MLSS) in rowers. The investigated athletes consisted of the elite Polish junior and senior male (n=14) and female (n=5) rowers. Each subject performed two tests on the Concept II rowing ergometer: one incremental exercise to determine the anaerobic threshold at 4 mmol•l-1 lactate concentration (AT4) and one 30-min exercise at a constant, submaximal intensity to estimate MLSS. The latter parameter was defined as the highest blood lactate level that within the last 20 min of exercising at the constant intensity increased by no more than 1.0 mmol•l-1. The estimated MLSS levels equalled to 3.66±0.93 mmol•l-1 and to 2.72±0.54 mmol•l-1 in the male and female rowers, respectively. In both groups of the athletes the obtained MLSS values markedly varied ranging from 1.83 to 5.93 mmol•l-1. Significant differences between the power output at AT4 and the power output at MLSS were noted both in the male (307±41 vs. 278±35 W) and the female (219±15 vs. 192±14 W) rowers. The ratios of the power output at MLSS to the power output at AT4 equalled to 91±4% and 88±2% in the male and female athletes, respectively. The obtained results indicate that in order to optimally select the intensity of the aerobic capacity-shaping training of both male and female rowers the power output at AT4 should be lowered by approximately 10%.
