During the last nearly 50 years, the blood lactate curve and lactate thresholds (LTs) have become important in the diagnosis of endurance performance. [] Key MethodA total of 25 different LT concepts were located. All concepts were divided into three categories. Several authors use fixed bLa during incremental exercise to assess endurance performance (category 1). Other LT concepts aim at detecting the first rise in bLa above baseline levels (category 2).
Blood lactate diagnostics in exercise testing and training.
TLDR
High-performance endurance athletes combining very high training volume with high aerobic power dedicate 70 to 90% of their training to intensity domain 1 (Intensity < Threshold) in order to keep glycogen homeostasis within sustainable limits.
Repeatability and predictive value of lactate threshold concepts in endurance sports
TLDR
One concept had both the highest repeatability and the highest predictability of cycling performance, and is therefore recommended to be used: the Dmax modified method.
Comparison of maximal lactate steady state with anaerobic threshold determined by various methods based on graded exercise test with 3-minute stages in elite cyclists
TLDR
The AT determined by D max and IAT methods based on the cycling GXT with 3-min stages provides a high agreement with the MLSS in elite cyclists, despite the high correlation with MLSS and low mean difference.
A novel device for detecting anaerobic threshold using sweat lactate during exercise.
TLDR
Continuous monitoring of lactate concentrations during exercise can provide additional information for detecting the VT1 and investigate the relationship between the lactate threshold (LT1) and ventilatory threshold (VT1).
Manipulating graded exercise test variables affects the validity of the lactate threshold and V˙O2peak
TLDR
It is apparent that V˙O2max and LT cannot be determined in a single GXT, even with the inclusion of a VEB, and a newly developed Modified Dmax method derived from GXT4 provided the most valid estimate of the MLSS.
A “Blood Relationship” Between the Overlooked Minimum Lactate Equivalent and Maximal Lactate Steady State in Trained Runners. Back to the Old Days?
TLDR
LEmin, an objective submaximal overlooked and underused BLRT, is found to be one of the best single MLSS predictors in endurance trained runners and is advocated to be shared, at least partly, with those controlling MLSS.
Lactate Equivalent for Maximal Lactate Steady State Determination in Soccer
TLDR
This study is the sole study providing specific operational regression equations to estimate the impractical gold standard MLSSV in soccer players by means of a BLT measured during a submaximal single-session test and results support LEmin to be one of the best single predictors of MLSS.
Lactate threshold by muscle electrical impedance in professional rowers.
TLDR
The utilization of the proposed method based on BIS parameters for estimating noninvasively the lactate threshold in rowing supports the utilization of its proposed method through bioelectrical impedance spectroscopy.
Comparison of maximal lactate steady state with V2, V4, individual anaerobic threshold and lactate minimum speed in horses
TLDR
This study corroborates the use of these tests, but reveals that adjustments in the protocols are necessary to obtain a better concordance between the tests and the MLSS.
The maximal metabolic steady state: redefining the ‘gold standard’
TLDR
Evidence is presented consistent with the contrary conclusion that as presently defined, MLSS naturally underestimates the actual maximal metabolic steady state; and that CP alone represents the boundary between discrete exercise intensity domains within which the dynamic cardiorespiratory and muscle metabolic responses to exercise differ profoundly.

42 Years Ago — Development of the Concepts of Ventilatory and Lactate Threshold
TLDR
The findings were interpreted as follows: during lower grades of performance the oxygen demand in the working muscle cells was saturated, whereas in the case of increasing exercise intensity an additional anaerobic metabolism was necessary.
Relationships of anaerobic threshold and onset of blood lactate accumulation with endurance performance
TLDR
It is suggested that variables related to an abrupt increase in blood lactate, together with several gas exchange responses, could explain endurance performance in a shorter distance to a greater extent than variablesrelated to a rigid threshold of 4 mmol·l−1.

The anaerobic threshold (AnT) is defined as the highest sustained intensity of exercise for which measurement of oxygen uptake can account for the entire energy requirement. At the AnT, the rate at
Ventilatory, lactate-derived and catecholamine thresholds during incremental treadmill running: relationship and reproducibility.
TLDR
In the present exercise protocol, there are systematic differences between the lactate-derived and ventilatory thresholds, in spite of a close relationship, and these must be taken into account in recommendations derived for training.
Dependence of the maximal lactate steady state on the motor pattern of exercise
TLDR
In rowing and cycling, the MLSS but not MLSS workload and MLSS intensity intraindividually depends on the motor pattern of exercise, indicating that task specific levels of MLSS occur at distinct levels of power output per unit of primarily engaged muscle mass.
Individual anaerobic threshold and maximum lactate steady state.
TLDR
The aim of the study was to investigate the validity of the IAT as a measure for the maximum lactate steady state (max Lass) and the monitoring of endurance training.
The reliability of lactate measurements during exercise.
TLDR
The results support the reliability of LT(VEL), LT(VO2), and LT(HR) measurement, which were established across days of testing.
Does anaerobic threshold correlate with maximal lactate steady-state?
TLDR
The present results demonstrate that AnT correlates with BLaSsmax, and the three hypotheses tested in this study were confirmed and could be explained by the subjects' age, the percentage of slow-twitch fibres and BLa levels at rest.
A simple method for individual anaerobic threshold as predictor of max lactate steady state.
TLDR
This protocol can be useful for practical use because: 1) the method of choosing the anaerobic threshold is easy to apply; 2) it does not require to reach the maximal effort; and 3) although in some cases the IATa could probably underestimate the workload of max Lass, theIATa can be regarded as guideline to define the intensity of endurance training.
Anaerobic threshold and lactate turnpoint
TLDR
Results lend a measure of support to the hypothesis of a positive relationship between the AT, LTP, and a pattern of recruitment of motor units with different enzyme profiles.
