ability to perform at very high intensity. You
receive a value based on the anaerobic
contribution to EPOC and the type of activity.
Repeated high- intensity
intervals of 10 to 120 seconds have a highly
beneficial impact on your anaerobic capability and
result in an improved anaerobic Training Effect.
It is important to know that your Training
Effect numbers (from 0.0 to 5.0) may seem
abnormally high during your first few
activities. It takes several activities for the
device to learn your aerobic and anaerobic
fitness.
You can add Training Effect as a data field
to one of your training screens to monitor
your numbers throughout the activity.

Pulse Oximeter
The Forerunner device has a wrist-based pulse
oximeter to gauge the saturation of oxygen in your
blood. Knowing your oxygen saturation can help
you determine how your body is adapting to
exercise and stress. Your device gauges your blood
oxygen level by shining light into the skin and
checking how much
light is absorbed. This is referred
to as SpO
2
.
On the device, your pulse oximeter readings appear as
an SpO
2
percentage. On your Garmin Connect account,
you can view additional details about your pulse
oximeter readings, including trends over multiple days
( Turning On Pulse Oximeter Sleep Tracking, page 21 ).
