Ground Contact Time Balance Data

Ground contact time balance measures your running symmetry and appears as a percentage of your total ground contact time. For

example, 51.3% with an arrow pointing left indicates the runner is spending more time on the ground when on the left foot. If your

data screen displays both numbers, for example 48–52, 48% is the left foot and 52% is the right foot.

While developing and testing running dynamics, the Garmin team found correlations between injuries and greater imbalances with

certain runners. For many runners, ground contact time balance tends to deviate further from 50–50 when running up or down hills.

Most running coaches agree that a symmetrical running form is good. Elite runners tend to have quick and balanced strides.

You can watch the color gauge or data field during your run or view the summary on your Garmin Connect account after your run.

As with the other running dynamics data, ground contact time balance is a quantitative measurement to help you learn about your

running form.

Vertical Oscillation and Vertical Ratio Data

The data ranges for vertical oscillation and vertical ratio are slightly different depending on the sensor and whether it is positioned at

the chest (HRM-Pro, HRM-Run, or HRM-Tri accessories) or at the waist (Running Dynamics Pod accessory).

Tips for Missing Running Dynamics Data

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

tips.

• Make sure you have a running dynamics accessory, such as

the HRM-Pro accessory.

Accessories with running dynamics have on the front of the

module.

• Pair the running dynamics accessory with your Forerunner

device again, according to the instructions.

• If you are using the HRM-Pro accessory, pair it with your

Forerunner device using ANT+ technology, rather than

Bluetooth technology.

• If the running dynamics data display shows only zeros, make

sure the accessory is worn right-side up.

NOTE: Ground contact time and balance appears only while

running. It is not calculated while walking.

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. For

more information, go to www.garmin.com/performance-data

/running/.

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

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.

Predicted race times: Your device uses the VO2 max. estimate

and your training history to provide a target race time based

on your current state of fitness.

HRV stress test: The heart rate variability (HRV) stress test

requires a Garmin chest heart rate monitor. The device

records your heart rate variability while standing still for 3

minutes. It provides your overall stress level. The scale is 1 to

100, and a lower score indicates a lower stress level.

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.

Functional threshold power (FTP): The device uses your user

profile information from the initial setup to estimate your FTP.

For a more accurate rating, you can conduct a guided test.

Lactate threshold: Lactate threshold requires a chest heart rate

monitor. Lactate threshold is the point where your muscles

start to rapidly fatigue. Your device measures your lactate

threshold level using heart rate data and pace.

Turning Off Performance Notifications

Some performance notifications appear upon completion of your

activity. Some performance notifications appear during an

activity or when you achieve a new performance measurement,

such as a new VO2 max. estimate. You can turn off the

performance condition feature to avoid some of these

notifications.

Select Physiological Metrics > Perf. Condition.

Detecting Performance Measurements Automatically

The Auto Detection feature is turned on by default. The device

can automatically detect your maximum heart rate, and lactate
