Lactic Acid Threshold

Lactic acid threshold is the point during exercise when your body starts to produce lactic acid faster than it can be cleared away, leading to a feeling of muscle fatigue or burning. It marks the intensity level at which your muscles switch from primarily using oxygen to produce energy to a process that doesn't need oxygen and generates lactic acid as a byproduct. Recognizing this threshold helps athletes train more effectively, improving endurance and performance by gradually increasing exercise intensity without overloading the muscles.
