Anaerobic threshold

Anaerobic threshold, also known as lactate threshold, is the exercise intensity at which lactate production exceeds lactate clearance. It is an important parameter for endurance athletes, as it marks the transition from predominantly aerobic to anaerobic metabolism. At this threshold, the body is no longer able to rely solely on oxygen to produce energy, and starts to rely on other metabolic pathways that produce lactate as a byproduct.

By training at or near the anaerobic threshold, athletes can improve their ability to tolerate and clear lactate, thus delaying the onset of fatigue and allowing them to sustain a higher intensity for longer periods of time. This can be achieved through various training methods, such as interval training and tempo runs.

It’s important to note that the anaerobic threshold is not a fixed value and can be influenced by various factors such as fitness level, environmental conditions, and individual differences. Therefore, athletes should regularly assess their threshold through lactate testing or other methods to ensure their training is appropriately targeted.
