Stress testing

Stress testing preparation

Attention: a sports medical examination is always required before a stress test may be conducted. This examination may not be older than two years.
  • Please read the “informed consent,” sign it and bring it with you to the stress test. You may download it here: download
  • Two days prior to the stress test, avoid extreme effort: residual effects will distort the results of the test, making it difficult to interpret correctly.
  • Nutrition:
    • two days prior to testing, make your diet heavy on the carbs
    • ideally, have a light meal ahead of the stress test; take care not to begin this hungry
    • on the day of the stress test, take no drink containing caffeine
  • Runners: bring your own – clean – running shoes.
  • Cyclists: bring your own bicycle frames, with a clean chain
  • After the stress test, you will have an opportunity to take a shower.

Conduct of stress testing

Conduct of stress testing

  • The testing begins with an easy warming up, usually 10 minutes. The intensity is then increased every step depending on the condition of the individual.  For cyclists, this may be 40 watt per 6 minutes; for runners 1.8 km/h per 3 minutes.
  • In order to determine the maximum values of your heart rate and lactic acid production, it is essential that you give the test your maximum effort.
  • If needed, both heart rate and rhythm are continuously recorded by means of a stress ECG: a reduction of oxygen supply to the heart sometimes only comes about when the heart is heavily stressed.
  • When certain deviations are noted during the sports medical examination, then a stress ECG is indicated. This is done without the lactate test and serves exlusively to monitor the heart’s functioning under heavy load.
  • The concentration of lactate level in the blood is determined at the end of each stress phase, and at the end of the test. Blood is taken by a tiny puncture in a finger, or in an earlobe.

Stress testing, continued

Based on your stress test, you will receive a complete and thorough report concerning your training zones, and an explanation of those zones.
