The present study aimed to investigate the effect of stage duration in incremental protocols on lactate threshold (LT), determined by different methods. Sixteen semi-professional soccer-players performed a 4-min stage incremental discontinuous (DP) and two maximal incremental running continuous (1 km h −1 · min −1 , CP1; and 1 km h −1 ·2 min −1 CP2) protocols. Blood-lactate concentration [La − ] was measured at baseline and during the protocols. LT was determined using D MAX , D MAX-MOD , 4-mM⋅L −1 , Δ1-mM⋅L −1 and Log-Log methods. Log-Log showed no difference in LT between CP1, CP2 and DP. Conversely, LT was determined at higher velocity in CP1 than CP2 for D MAX (15.2 ± 0.5 vs 14.4 ± 1.2 km⋅h −1 , P = 0.002), D MAX-MOD (16.0 ± 0.5 vs 14.7 ± 1.3 km⋅h −1 , P < 0.001), 4-mM⋅L −1 (15.5 ± 1.4 vs 14.4 ± 1.2 km⋅h −1 , P < 0.001), Δ1-mM⋅L −1 (15.5 ± 1.3 vs 14.4 ± 1.2 km⋅h −1 , P < 0.001). Higher LT in CP1 than DP for D MAX (15.2 ± 0.5 vs 13.0 ± 1.0 km⋅h −1 , P < 0.001) and D MAX-MOD (16.0 ± 0.5 vs 13.6 ± 1.6 km⋅h −1 , P < 0.001) was found (P < 0.001). Log-Log resulted in shorter but accurate protocols to determine LT. [ABSTRACT FROM AUTHOR]
