Heat And Altitude Performance Acclimation; Acute Load; Training Load Focus; Recovery Time - Garmin Tactix Delta Owner's Manual

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 tactix Delta 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 widget.
NOTE: The heat acclimation feature is available only for GPS activities and requires weather data from your
connected phone.

Acute Load

Acute load is a weighted sum of your excess post-exercise oxygen consumption (EPOC) for the last several
days. The gauge indicates whether your current load is low, optimal, high, or very high. The optimal range is
based on your individual fitness level and training history. The range adjusts as your training time and intensity
increase or decrease.

Training Load Focus

In order to maximize performance and fitness gains, training should be distributed across three categories: low
aerobic, high aerobic, and anaerobic. Training load focus shows you how much of your training is currently in
each category and provides training targets. Training load focus requires at least 7 days of training to determine
if your training load is low, optimal, or high. After 4 weeks of training history, your training load estimate will
have more detailed target information to help you balance your training activities.
Below targets: Your training load is lower than optimal in all intensity categories. Try increasing the duration or
frequency of your workouts.
Low aerobic shortage: Try adding more low aerobic activities to provide recovery and balance for your higher
intensity activities.
High aerobic shortage: Try adding more high aerobic activities to help improve your lactate threshold and VO2
max. over time.
Anaerobic shortage: Try adding a few more intense, anaerobic activities to improve your speed and anaerobic
capacity over time.
Balanced: Your training load is balanced and provides all-around fitness benefits as you continue training.
Low aerobic focus: Your training load is mostly low aerobic activity. This provides a solid foundation and
prepares you for adding more intense workouts.
High aerobic focus: Your training load is mostly high aerobic activity. These activities help to improve lactate
threshold, VO2 max., and endurance.
Anaerobic focus: Your training load is mostly intense activity. This leads to rapid fitness gains, but should be
balanced with low aerobic activities.
Above targets: Your training load is higher than optimal, and you should consider scaling back the duration and
frequency of your workouts.

Recovery Time

You can use your Garmin device with wrist-based heart rate or a compatible chest heart rate monitor to display
how much time remains before you are fully recovered and ready for the next hard workout.
NOTE: The recovery time recommendation uses your VO2 max. estimate and may seem inaccurate at first. The
device requires you to complete a few activities to learn about your performance.
The recovery time appears immediately following an activity. The time counts down until it is optimal for you to
attempt another hard workout. The device updates your recovery time throughout the day based on changes in
sleep, stress, relaxation, and physical activity.
