Proprietary data

Proprietary values, such as Recovery time, Lactate threshold, Aerobic Training Effect, VO2max, etc, are provided by your sports watch manufacturer and may have been acquired by the latter under license from a third company.

Proprietary VO2max deviates

Experience has shown that the proprietary VO²max value is somewhat higher during low intensity training then the VO²max value Tredict shows. In other words, the value is rather too low for training sessions with high intensity. The exact algorithm behind this is not known to us.

Body Battery

Body Battery measures your available energy reserves on a scale of 5 to 100. It increases mainly through sleep and rest, and decreases through activity and stress, with heart rate variability playing the biggest role.

Recovery time

The recovery time is the estimated time until you have fully recovered and are ready for your next intense training session, and ranges from 6 hours to 4 days. It is primarily calculated based on the training effect of the activity and is updated throughout the day based on sleep, stress, relaxation and physical activity.

Performance condition

Performance status is a real-time assessment of your current performance relative to your average fitness level on a scale from -20 to +20. It is calculated after 6 to 20 minutes of activity based on pace, heart rate and heart rate variability, and roughly corresponds to the percentage deviation from your baseline VO2max value.

Aerobic training effect

The aerobic training effect describes the impact of an activity on your aerobic fitness on a scale of 0.0 to 5.0. It is calculated based on your heart rate and the increase in oxygen uptake following exercise, and is primarily enhanced by steady-state exercise at a moderate intensity or longer intervals of over 180 seconds.

Anaerobic training effect

The anaerobic training effect describes the impact of an activity on your ability to train at very high intensity, on a scale of 0.0 to 5.0. It is calculated using heart rate and speed or power, and is primarily increased by repeated high-intensity intervals lasting between 10 and 120 seconds.
