Lactate test for athletes

Why should I as an athlete take a lactate test?

If you go in for endurance sports (e.g., triathlon, half-marathon, running, cycling) and want to train in future according to your heart rate, then you should undergo a lactate test (check of the concentration of lactic acid in the blood under physical stress and exertion).
The performance of a lactate test is an irreplaceable aid in the optimisation of your training plan and to increase your personal performance capability!
The determination of the lactate content in the blood allows the objective assessment of your current state of training. For the athlete, individual heart rate training zones can be defined in this way. If the required oxygen to produce energy can no longer be provided sufficiently under sporting stress (so-called aerobic-anaerobic transition), the organism must increasingly obtain the energy elsewhere. This process produces lactate, i.e. the musculature becomes acidotic. The concentration of lactate therefore gives indications of your individual aerobic/anaerobic threshold, which is important for your training plan.

Procedure of a lactate test

After the consultation and the initial examination, a step test is performed on a bicycle ergometer (sitting or semi-prone) or a treadmill. The test starts at a gentle cycling or walking pace on the treadmill. Blood is taken from the earlobe every 3 minutes to determine the lactate level. The stress test is interrupted briefly for this purpose. The performance is then gradually increased in stages of 25-50 Watt.
This time is required until the change of the lactate produced in the musculature becomes measurable in the capillary blood of the ear.
This procedure is repeated until the aerobic-anaerobic threshold is exceeded or the current endurance performance limit is reached. In addition to the achieved stress and the lactate levels, the heart rate is also measured. This ten provides information/values which are ideally suitable for making specific recommendations with regard to the heart rate stress of the training.


For a sports lactate test, we currently charge € 280. This includes a consultation with full body status, an electrocardiogram, ergometry, and corresponding consultation or training information with the measured heart rate and lactate values (and definition of the individual aerobic/anaerobic threshold) and of course the required lactate determination.
Should further examinations be conducted on request, these would have to be charged separately (on the basis of the official scale of charges for doctors - GOÄ).
Legal care programmes provide for a so-called check-up every two years and are therefore patchy in terms of scope (short consultation, exploratory examination, urine test strips, blood checked only for cholesterol and glucose).
We will also be happy to carry out an extended check-up, although this will have to be charged additionally. We cannot reconcile statutory services against private services if this relates to individual health services, e.g. in terms of medical suitability for sport (lactate) or diving.
