Optimizing Training Zones Using Metabolic Shift
Heart rate zones are not accurate for everyone due to individual variations and standard deviations. Lactate meter and other systems may not work effectively either. The most reliable way to determine training zones is by identifying the metabolic shift using the rate of respiration. Conducting a zone two test, also known as a VT one test, involves gradually increasing pace and monitoring respiration until reaching the point where speaking a 15 to 20 word sentence without interruption is no longer possible, indicating the inflection point of increased respiration and change in blood pH.
