Key result
Calculated maximal lactate steady-state (cMLSS) showed good agreement with the reverse lactate test (ICC 0.806, p=0.268) but differed significantly from the second ventilatory threshold (p=0.012).
Why the study?
Calculated maximal lactate steady-state (cMLSS) is practical and time-efficient, but its agreement with traditional approaches to distinguish the heavy from severe exercise intensity domains required evaluation.
Population
15 triathletes (3 women, 12 men)
Comparison
cMLSS vs traditional approaches (VT2 and RLT)
Design
Cross-sectional physiological study

RLT may align better with cMLSS than VT2 for threshold estimation in athletes; leaves open prospective validation before guiding training.
Cross-Sectional (n=15)
Effect estimate: ICC 0.806 (RLT vs cMLSS)
p-value: p=0.268
Calculated maximal lactate steady-state (cMLSS) shows good agreement with the reverse lactate test and may provide a practical method for physiological threshold determination in athletes.
Siemers et al. (2026) conducted a cross-sectional in Recreational triathletes and cyclists (n=15). Calculated maximal lactate steady-state (cMLSS) vs. Traditional approaches (VT2, RLT) was evaluated on Power at experimental thresholds (VT2, RLT) compared to cMLSS (ICC 0.806 (RLT vs cMLSS), p=0.268). Calculated maximal lactate steady-state (cMLSS) showed good agreement with the reverse lactate test (ICC 0.806, p=0.268) but differed significantly from the second ventilatory threshold (p=0.012).
