What Is Lactate Threshold?

Lactate threshold (or anaerobic threshold) is a good predictor of athletic endurance performance. The lactate threshold is a point during physical activity where blood lactate builds up faster than your body can remove it.

With proper training, athletes can increase their lactate threshold and can tolerate higher intensity exercise for longer amounts of time.

Knowing your lactate threshold can help you determine a training regimen to improve your athletic performance.
