Using the Stress Level Glance
The stress level glance displays your current stress level and a graph of your stress level for the last several
hours. It can also guide you through a breathing activity to help you relax (
).
1 While you are sitting or inactive, press UP or DOWN to view the stress level glance.
2 Press START.
3 Select an option:
• Press DOWN to view additional details.
TIP: Blue bars indicate periods of rest. Orange bars indicate periods of stress. Gray bars indicate times
when you were too active to determine your stress level.
• Press START to start a Breathwork activity.
Performance Measurements
These performance measurements are estimates that can help you track and understand your training activities
and race performances. The measurements require a few activities using wrist-based heart rate or a compatible
chest heart rate monitor. Cycling performance measurements require a heart rate monitor and a power meter.
These estimates are provided and supported by Firstbeat Analytics

.
NOTE: The estimates may seem inaccurate at first. The watch requires you to complete a few activities to learn
about your performance.
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 (
About VO2 Max. Estimates, page 21
).
Predicted race times: The watch uses the VO2 max. estimate and your training history to provide a target race
time based on your current state of fitness (
Viewing Your Predicted Race Times, page 22
).
HRV status: The watch analyzes your wrist heart rate readings while you are sleeping to determine your heart
rate variability (HRV) status based on your personal, long-term HRV averages (
Heart Rate Variability Status,
).
Performance condition: Your performance condition is a real-time assessment after 6 to 20 minutes of activity.
It can be added as a data field so you can view your performance condition during the rest of your activity. It
compares your real-time condition to your average fitness level (
Performance Condition, page 24
).
Lactate threshold: Lactate threshold requires a chest heart rate monitor. Lactate threshold is the point where
your muscles start to rapidly fatigue. Your watch measures your lactate threshold level using heart rate data
and pace (
).
Power curve (cycling): The power curve displays your sustained power output over time. You can view your
power curve for the previous month, three months, or twelve months (
Viewing Your Power Curve, page 25
).
