Garmin 920XT Manuel Du Propriétaire

The running dynamics screen displays a color gauge for the primary metric. You can display cadence, vertical oscillation, or ground 

contact time as the primary metric. The color gauge shows you how your running dynamics data compares to those of other 

runners. The color zones are based on percentiles.
Garmin has researched many runners of all different levels. The data values in the red or orange zones are typical for less 

experienced or slower runners. The data values in the green, blue, or purple zones are typical for more experienced or faster 

runners. Less experienced runners tend to exhibit longer ground contact times, higher vertical oscillation, and lower cadence than 

more experienced runners. However, taller runners typically have slightly slower cadences and slightly higher vertical oscillation. Go 

to 

 for more information on running dynamics. For additional theories and interpretations of running dynamics data, 

you can search reputable running publications and websites.

If running dynamics data does not appear, you can try these 

tips.
• Make sure you have the HRM-Run accessory.

The HRM-Run accessory has   on the front of the module.

• Pair the HRM-Run accessory with your Forerunner again, 

according to the instructions.

• If the running dynamics data display zeros, make sure the 

HRM-Run module is worn right-side up.
NOTE: Ground contact time appears only while running. It 

cannot be calculated while walking.

If the heart rate data is erratic or does not appear, you can try 

these tips.
• Reapply moisture to the electrodes and contact patches.
• Tighten the strap on your chest.
• Warm up for 5–10 minutes.
• Wash the strap after every seven uses (

).

• Wear a cotton shirt or wet your shirt if suitable for your 

activity.
Synthetic fabrics that rub or flap against the heart rate 

monitor can create static electricity that interferes with heart 

rate signals.

• Move away from sources that can interfere with your heart 

rate monitor.
Sources of interference may include strong electromagnetic 

fields, some 2.4 GHz wireless sensors, high-voltage power 

lines, electric motors, ovens, microwave ovens, 2.4 GHz 

cordless phones, and wireless LAN access points.

VO2 max. is the maximum volume of oxygen (in mililiters) you 

can consume per minute per kilogram of body weight at your 

maximum performance. In simple terms, VO2 max. is an 

indication of athletic performance and should increase as your 

level of fitness improves. VO2 max. estimates are provided and 

supported by Firstbeat® Technologies Ltd. The Forerunner 

device has separate VO2 max. estimates for running and 

cycling. You can use your Garmin device paired with a 

compatible heart rate monitor and power meter to display your 

cycling VO2 max. estimate. You can use your Garmin device 

paired with a compatible heart rate monitor to display your 

running VO2 max. estimate.

Before you can view your VO2 max. estimate, you must put on 

the heart rate monitor and pair it with your device (

). If your Forerunner device was packaged with a 

heart rate monitor, the devices are already paired. For the most 

accurate estimate, complete the user profile setup (

), and set your maximum heart rate (

).

NOTE: The estimate may seem inaccurate at first. The device 

requires a few runs to learn about your running performance.

Run for at least 10 minutes outdoors.

After your run, select Save.
