Heart Rate Training Zones Calculator. Zone 4 @Z4, LACTATE THRESHOLD. Intensity: 89-94% of your max HR. Also known as the anaerobic threshold, this type of training increases maximum performance capacity enhances lung capacity, and improves high-speed endurance. That said, this type of training is very challenging - it's not an effort
However, in this article, threshold 1 (T1) (e.g., first lactate, ventilatory or gas exchange, and heart rate variability (HRV) thresholds) lies between the moderate and heavy domains [2,3,4] and threshold 2 (T2) (e.g., second lactate threshold, second ventilatory threshold, or respiratory compensation point) lies between the heavy and severe
Defining Cycling Power Zones. Power at lactate threshold (LT) is the most important physiological determinant of endurance cycling performance, since it integrates VO2max, the percentage of VO2max that can be sustained for a given duration, and cycling efficiency. As such, it is more logical to define training zones relative to an athlete's
Heart rate was continuously monitored (RS400, Polar, Finland), gas exchange was recorded breath by breath using indirect calorimetry and capillary blood samples were obtained and analyzed every 2 min (i.e., each 50 W increments). Lactate Threshold (LT) was determined by examining the lactate concentration-workload relationship ([Lact] blood

In untrained individuals, the lactate threshold occurs at ~50-60% of VO2 max - equivalent to ~55-65% of maximum heart rate. Among well-trained athletes , this increases to between 75 and 85% VO2max (~80-90% maximum heart rate)
