Performance Condition
As you perform a running activity, the performance condition
feature analyzes your pace, heart rate, and heart rate variability
to make a real-time assessment of your ability to perform
compared to your average fitness level. It is approximately your
real-time percentage deviation from your baseline VO2 max.
estimate.
Performance condition values range from -20 to +20. After the
first 6 to 20 minutes of your activity, the device displays your
performance condition score. For example, a score of +5 means
that you are rested, fresh, and capable of a good run. You can
add performance condition as a data field to one of your training
screens to monitor your ability throughout the activity.
Performance condition can also be an indicator of fatigue level,
especially at the end of a long training run.
NOTE: The device requires a few runs with a heart rate monitor
to get an accurate VO2 max. estimate and learn about your
running ability (About VO2 Max. Estimates, page 15).
About Training Effect
Training Effect measures the impact of an activity on your
aerobic and anaerobic fitness. Training Effect accumulates
during the activity. As the activity progresses, the Training Effect
value increases, telling you how the activity has improved your
fitness. Training Effect is determined by your user profile
information, heart rate, duration, and intensity of your activity.
Aerobic Training Effect uses your heart rate to measure how the
accumulated intensity of an exercise affects your aerobic fitness
and indicates if the workout had a maintaining or improving
effect on your fitness level. Your EPOC accumulated during
exercise is mapped to a range of values that account for your
fitness level and training habits. Steady workouts at moderate
effort or workouts involving longer intervals (>180 sec) have a
positive impact on your aerobic metabolism and result in an
improved aerobic Training Effect.
Anaerobic Training Effect uses heart rate and speed (or power)
to determine how a workout affects your 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 16). For more information on pulse oximeter
accuracy, go to garmin.com/ataccuracy.
Getting Pulse Oximeter Readings
You can manually begin a pulse oximeter reading on your
device at any time. The accuracy of the reading can vary based
on your blood flow, the device placement on your wrist, and your
stillness.
1
Wear the device above your wrist bone.
The device should be snug but comfortable.
2
Select UP or DOWN to view the pulse oximeter widget.
3
Select START.
4
Hold the arm wearing the device at heart level while the
device reads your blood oxygen saturation.
5
Keep still.
The device displays your oxygen saturation as a percentage.
NOTE: You can customize the pulse oximeter settings in your
Garmin Connect account.
Turning On Pulse Oximeter Sleep Tracking
You can set your device to continuously measure your blood
oxygen saturation while you sleep.
NOTE: Unusual sleep positions can cause abnormally low
sleep-time SpO2 readings.
1
From the pulse oximeter widget, hold UP.
2
Select Sleep Pulse Ox > On.
Tips for Erratic Pulse Oximeter Data
If the pulse oximeter data is erratic or does not appear, you can
try these tips.
• Remain motionless while the device reads your blood oxygen
saturation.
• Wear the device above your wrist bone. The device should
be snug but comfortable.
• Hold the arm wearing the device at heart level while the
device reads your blood oxygen saturation.
• Use a silicone band.
• Clean and dry your arm before putting on the device.
• Avoid wearing sunscreen, lotion, and insect repellent under
the device.
• Avoid scratching the optical sensor on the back of the device.
