In contrast, at the anaerobic threshold (AnT) the exercise is at an intensity beyond which blood lactate concentration is linearly related to exercise intensity, but increases with both exercise intensity and duration. (wikipedia.org)
The blood lactate concentration at the anaerobic threshold is called the "maximum steady-state lactate concentration" (MLSS). (wikipedia.org)
Several methods are used for estimating the anaerobic threshold (AT) during exercise. (jssm.org)

If a training programme is designed so that exercise occurs in the anaerobic threshold range, it can have a positive impact on the metabolism, increase muscle cell contractions, improve muscle cell repair, increase blood capillaries and improve cardiac function. (ekfdiagnostics.com)

The onset of blood lactate accumulation (OBLA) is often confused with the lactate threshold. (wikipedia.org)
The results from the LT test were used to determine velocity at lactate threshold (vLT), velocity at onset of blood lactate accumulation (vOBLA), maximal oxygen uptake (VO 2max ), and the heart rate-blood lactate profile for calculation of internal TL (individualized training impulse, or iTRIMP). (humankinetics.com)

VO2max is a valued measurement of cardiovascular fitness in the Sport industry due to its ability to indicate cardiovascular fitness, as well as the pulmonary and muscular systems efficiency throughout the duration of the exercise (Brown, Miller and Eason). (bartleby.com)
Once threshold was determined, test speed was increased every minute until volitional exhaustion for assessment of maximal oxygen uptake (Vo2max), maximum heart rate (HRmax), and performance time. (northumbria.ac.uk)

Blood lactate concentration at the end of 4-min stages was assessed to determine lactate threshold. (northumbria.ac.uk)
Up to a certain threshold, the body can clear lactate at a rate at which, although there is an elevated concentration of lactate in the blood, the concentration does not impede muscle function. (ekfdiagnostics.com)

A corresponding threshold for serum folate has not been established. (cdc.gov)
21.0 vs. 40.5 nmol/L). CONCLUSIONS: The estimated serum folate threshold for optimal NTD prevention was similar to previous reports (24.3 vs. 25.6 nmol/L) among participants with sufficient vitamin B(12) status. (cdc.gov)

FTP was conceptualized as a field-based practical method of estimating a threshold phenomena using cycling power meter technology. (georgeron.com)

Knowing your lactate threshold can help you determine how hard to train or when to push yourself during a race. (garmin.com)
It is therefore important to determine the lactate threshold at which training is most effective. (ekfdiagnostics.com)

Body mass, body fat, and girth measurements (except the calf) decreased for both subjects. (tennessee.edu)

Typical error of measurement (TEM) with associated 90% confidence intervals, limits of agreement, paired sample t tests, and least products regression were used to assess the reproducibility of scores. (northumbria.ac.uk)

There are four commonly used field tests for calculating lactate thresholds. (advnture.com)

For instance, let's say we knew that at a particular site the O2 sat breakpoint would occur at below the lactate threshold, but at different site the breakpoint is near the lactate threshold, and a third site has a breakpoint at above the respiratory compensation point. (muscleoxygentraining.com)

Some of the reasons include the determination of tolerance or sustainable threshold. (beagles.org.uk)
