This study evaluated the accuracy of a modified-lactate-minimum-test (mLMT), a modified-reverse-lactate-threshold-test (mRLT), in comparison to two established threshold concepts (OBLA & mDmax) to determine power output at maximal-lactate-steady-state (MLSS) in cycling. Nineteen subjects performed an mLMT, an mRLT, a graded-exercise-test (100W start, +20W every 3 min) and 3 or more constant-load tests of 30 minutes to determine power output at MLSS. The mLMT and mRLT both consisted of an initial lactate priming-segment, followed by a short recovery phase. Afterwards, the initial load of the subsequent incremental- or reverse-segment was calculated individually and was increased or decreased by 10W every 90 sec respectively. The mean difference to MLSS was +2 ± 7W (mLMT), +5 ± 10W (mRLT), +9 ± 21W (OBLA) and +6 ± 14W (mDmax). The correlation between power output at MLSS and mLMT was highest (r=0.99), followed by mRLT (r=0.98), mDmax (r=0.95) and OBLA (r=0.90). Due to the higher accuracy of the mLMT and the mRLT to determine MLSS compared to OBLA and mDmax, we suggest both tests as valid and meaningful concepts to estimate power output at MLSS in one single test in moderately up to well-trained athletes. Additionally, our modified tests provide anaerobic data and do not require detailed knowledge of the subjects' training status compared to previous LMT- or RLT-protocols.
