Recognizing Overtraining Syndrome
There are several ways you can objectively measure some signs of overtraining. One is by documenting your heart rates over time. Track your aerobic heart rate at a specific exercise intensities and speed throughout your training and write it down. If your pace starts to slow, your resting heart rate increases and you experience other symptoms, you may heading into overtraining syndrome.
You can also track your resting heart rate each morning. Any marked increase from the norm may indicate that you aren’t fully recovered.
Another way to test recover to use something called the orthostatic heart rate test, developed by Heikki Rusko while working with cross country skiers. To obtain this measurement:
- Lay down and rest comfortably for 10 minutes the same time each day (morning is best).
- At the end of 10 minutes, record your heart rate in beats per minute.
- Then stand up
- After 15 seconds, take a second heart rate in beats per minute.
- After 90 seconds, take a third heart rate in beats per minute.
- After 120 seconds, take a fourth heart rate in beats per minute.
Well rested athletes will show a consistent heart rate between measurements, but Rusko found a marked increase (10 beats/minutes or more) in the 120 second-post-standing measurement of athletes on the verge of overtraining. Such a change may indicate that you have not recovered from a previous workout, are fatigued, or otherwise stressed and it may be helpful to reduce training or rest another day before performing another workout.
