Running velocity from lactate-minimum method did not achieve lactate steady state in trained middle-distance runners, showing variability in blood lactate during a 30-min run.
Does the running velocity derived from the lactate-minimum approach elicit a lactate steady state in male trained middle-distance runners?
The lactate-minimum approach does not reliably elicit a lactate steady state in highly trained male middle-distance runners, highlighting the need for direct MLSS verification.
Despite stable cardiorespiratory and substrate-utilization profiles, the significant variability in blood lactate concentration during the 30-minute constant-load run indicates that the running velocity derived from the lactate-minimum approach did not elicit a lactate steady state in this trained cohort. These findings suggest that physiological responses at the MLaSS-derived intensity may differ from classical steady-state expectations in highly trained endurance runners and highlight the need for direct MLSS verification in future studies.
