Conducting An Ftp Test; Lactate Threshold - Garmin FENIX E Owner's Manual

Conducting an FTP Test

Before you can conduct a test to determine your functional threshold power (FTP), you must pair a chest heart
rate monitor and a power meter with your device
your VO2 max. estimate
NOTE: The FTP test is a challenging workout that takes about 30 minutes to complete. Choose a practical and
mostly flat route that allows you to ride at a steadily increasing effort, similar to a time trial.

5 Follow the on-screen instructions.
After you begin your ride, the device displays each step duration, the target, and current power data. A
message appears when the test is complete.
6 After you complete the guided test, complete the cool down, stop the timer, and save the activity.
Your FTP appears as a value measured in watts per kilogram, your power output in watts, and a position on
the color gauge.
7 Select an option:
• Select Accept to save the new FTP.
• Select Decline to keep your current FTP.

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 116). You can turn on the Auto Detection feature to automatically record your
lactate threshold during an activity.
