Lactate Threshold
Lactate threshold is the exercise intensity at which lactate (lactic acid) starts to accumulate in the bloodstream.
In running, this intensity level is estimated in terms of pace, heart rate, or power. When a runner exceeds the
threshold, fatigue starts to increase at an accelerating rate. For experienced runners, the threshold occurs at
approximately 90% of their maximum heart rate and between 10 km and half-marathon race pace. For average
runners, the lactate threshold often occurs well below 90% of maximum heart rate. Knowing your lactate
threshold can help you determine how hard to train or when to push yourself during a race.
If you already know your lactate threshold heart rate value, you can enter it in your user profile settings
Your Heart Rate Zones, page 73). You can turn on the Auto Detection feature to automatically record your
lactate threshold during an activity.
Training Status
These measurements are estimates that can help you track and understand your training activities. The
measurements require you to complete activities for two weeks using wrist-based heart rate or a compatible
chest heart rate monitor. Cycling performance measurements require a heart rate monitor and a power meter.
The measurements may seem inaccurate at first when the watch is still learning about your performance.
These estimates are provided and supported by Firstbeat Analytics. For more information, go to

Training status: Training status shows you how your training affects your fitness and performance. Your
training status is based on changes to your VO2 max., acute load, and HRV status over an extended time
period.
VO2 max.: VO2 max. is the maximum volume of oxygen (in milliliters) you can consume per minute per kilogram
of body weight at your maximum performance
heat and altitude corrected VO2 max. values when you are acclimating to high heat environments or high
altitude (Heat and Altitude Performance Acclimation,
HRV: HRV is your heart rate variability status over the last seven days
Acute load: Acute load is a weighted sum of your recent exercise load scores including exercise duration and
intensity. (Acute Load,
Recovery time: The recovery time displays how much time remains before you are fully recovered and ready for
the next hard workout
