Training Effect (TE)

Training Effect is an accurate measurement of how hard you have trained. To calculate your personal Training Effect, Suunto heart rate monitors use data from your personal profile and combine it with a real-time analysis of your physiological progress. Your heart rate monitor then formulates your Training Effect, presented on a scale from 1-5.
“I really value the Training Effect analysis. It gives me great info about my condition and real-time levels of exertion.
This is what technology should be about.”
Jonathan Wyatt, Mountain Runner Legend, 7-time Mountain Running World Champion
See the table for a detailed analysis of what each number represents:
| Training Effect (TE) |
Interpretation |
| |
|
| 1. Minor Training Effect |
This workout improves your recovery time and basic endurance when performing consistently for an hour or more. In general, though, it does not significantly improve your aerobic performance. |
|
|
| 2. Maintaining Training Effect |
This workout helps you maintain a consistent level of aerobic performance. It also helps improve your respiratory and cardiovascular conditions, and will allow you to train at a higher intensity in the future. |
|
|
| 3. Improving Training Effect |
This workout helps improve your aerobic performance if repeated 2 to 4 times per week. Training at this level does not yet require the need for specific lengths of recuperation time. |
|
|
| 4. Highly improving Training Effect |
This workout highly improves your aerobic performance, if repeated 1 to 2 times per week. In order to achieve optimal development, it requires 2 to 3 recuperative workouts (with a Training Effect of 1–2) per week. |
|
|
| 5. Over-reaching Training Effect |
This workout helps you greatly improve your aerobic performance, but only if followed by a sufficient recuperation period. Training at this level requires an extremely high level of exertion and should not be performed often. |
