    The heart rate-based lactate minimum test is a highly reproducible exercise test. However, the relation between lactate minimum determined by this test and maximal lactate steady state in running and cycling is still unclear. Twelve endurance-trained men performed this test in running and cycling. Exercise intensity at maximal lactate steady state was determined by performing several constant heart rate endurance tests for both exercise modes. Heart rate, power output, lactate concentration, oxygen uptake and rating of perceived exertion at lactate minimum, maximal lactate steady state and maximal performance were analysed. All parameters were significantly higher at maximal lactate steady state compared to lactate minimum for running and cycling. Significant correlations (p<0.05) between maximal lactate steady state and lactate minimum data were found. Peak heart rate and peak oxygen uptake were significantly higher for running versus cycling. Nevertheless, the exercise mode had no influence on relative (in percentage of maximal values) heart rate at lactate minimum (p=0.099) in contrast to relative power output (p=0.002). In conclusion, all measured parameters at lactate minimum were significantly lower but highly correlated with values at maximal lactate steady state in running and cycling, which allows to roughly estimate exercise intensity at maximal lactate steady state with one single exercise test.

    The determination of the maximal lactate steady state (MLSS) requires at least two constant load tests. Therefore, different testing procedures to indirectly determine MLSS based on one single test have been developed. One such method is the application of the lactate minimum tests (LMT), where workload and heart rate-based protocols exist. The latter showed significant correlations between parameters at lactate minimum (LM) and MLSS for running and cycling. However, LM clearly underestimated MLSS. Therefore, the aim of this study was to optimize the already existing test protocol in terms of an improved agreement between LM and MLSS. Fourteen healthy endurance-trained male athletes (age: 39.7±8.2 y; height: 180.9±6.2 cm; body mass: 78.6±7.1 kg) performed four different heart rate-based LMT protocols, the original and three new protocols. Additionally, they performed several constant heart rate endurance tests for assessing MLSS exercise intensity. Heart rate, blood lactate concentration, oxygen uptake and power at LM of two of our new test protocols with an increased start intensity were closer to and no longer different from MLSS data. We conclude that these two new test protocols can be used in practice to estimate heart rate-based MLSS by means of one single exercise test.
