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. Training Effect
is determined by your user profile information and training history, and heart rate, duration, and intensity of your
activity. There are seven different Training Effect labels to describe the primary benefit of your activity. Each
label is color coded and corresponds to your training load focus
phrase, for example, "Highly Impacting VO2 Max." has a corresponding description in your Garmin Connect
activity details.
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 excess post-exercise oxygen consumption (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.
You can add Aerobic Training Effect and Anaerobic Training Effect as data fields to one of your training screens
to monitor your numbers throughout the activity.

Heat and Altitude Performance Acclimation

Environmental factors such as high temperature and altitude impact your training and performance. For
example, high altitude training can have a positive impact on your fitness, but you may notice a temporary
VO2 max. decline while exposed to high altitudes. Your Approach S70 watch provides acclimation notifications
and corrections to your VO2 max. estimate and training status when the temperature is above 22ºC (72ºF) and
when the altitude is above 800 m (2625 ft.). You can keep track of your heat and altitude acclimation in the
training status glance.
NOTE: The heat acclimation feature is available only for GPS activities and requires weather data from your
connected phone.
