Garmin Forerunner 935 Benutzeranleitung

Vertical oscillation: Vertical oscillation is your bounce while 

running. It displays the vertical motion of your torso, 

measured in centimeters.

Ground contact time: Ground contact time is the amount of 

time in each step that you spend on the ground while 

running. It is measured in milliseconds.
NOTE: Ground contact time and balance are not available 

while walking.

Ground contact time balance: Ground contact time balance 

displays the left/right balance of your ground contact time 

while running. It displays a percentage. For example, 53.2 

with an arrow pointing left or right.

Stride length: Stride length is the length of your stride from one 

footfall to the next. It is measured in meters.

Vertical ratio: Vertical ratio is the ratio of vertical oscillation to 

stride length. It displays a percentage. A lower number 

typically indicates better running form.

Before you can view running dynamics, you must put on the 

HRM-Run

™

 accessory or HRM-Tri accessory and pair it with 

your device (

).

If your Forerunner was packaged with the heart rate monitor, the 

devices are already paired, and the Forerunner is set to display 

running dynamics.

Select START, and select a running activity.

Select START.

Go for a run.

Scroll to the running dynamics screens to view your metrics.

If necessary, hold UP to edit how the running dynamics data 

appears.

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

contact time, ground contact time balance, or vertical ratio as the primary metric. The color gauge shows you how your running 

dynamics data compare 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. More experienced runners tend to exhibit shorter ground contact times, lower vertical oscillation, lower vertical ratio, and 

higher cadence than less experienced runners. However, taller runners typically have slightly slower cadences, longer strides, and 

slightly higher vertical oscillation. Vertical ratio is your vertical oscillation divided by stride length. It is not correlated with height.
Go to 

running dynamics data, you can search reputable running publications and websites.

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.

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