Laktaatläve

Laktaatläve, often referred to as lactate threshold, is a concept in exercise physiology that describes the point at which lactic acid accumulates in the blood faster than it can be cleared. This accumulation leads to a decrease in performance and an increase in perceived exertion. It is typically measured in terms of heart rate or pace during exercise.

Understanding one's lactaatläve is important for athletes and fitness enthusiasts aiming to improve endurance. By training at or slightly below this threshold, individuals can gradually increase their capacity to sustain higher intensities of exercise for longer periods. This is achieved by enhancing the body's ability to produce and utilize energy aerobically and to buffer the resulting acidity.

There are several methods to determine lactaatläve, including laboratory-based tests involving blood lactate sampling and field tests that estimate the threshold based on heart rate and perceived exertion. Training programs often incorporate intervals at or near the lactaatläve to specifically target and improve this physiological marker. As an individual's fitness improves, their lactaatläve generally increases, allowing them to perform at a higher intensity before lactate begins to accumulate significantly.
