Conconi test
The Conconi test is a method to determine the individual heart rate and exercise intensity in terms of physical performance - measured by the training speed - at the anaerobic threshold for endurance training . Tests on the treadmill, on the bicycle ergometer or in field tests are common .
This test is a simple but conditionally suitable way of determining the anaerobic threshold (breaking off the linear relationship between performance and heart rate ) as an indicator of endurance performance. The speed of movement achieved is set in relation to the heart rate measured.
The test was developed by the Italian biochemist and amateur cyclist Francesco Conconi and establishes a relationship between exercise intensity and pulse rate.
execution
A steady, step-by-step increase in the load levels is essential for implementation. The pace is slow and relaxed at the beginning and is increased in each step (e.g. when running every 200 meters by 0.5 km / h or when cycling every two minutes by 1 km / h or on the ergometer by 10 to 20 Watt). It is advantageous to choose the length of the steps so that the heart rate has enough time to adapt. 1 min should be sufficient, a shorter time can be problematic because the heart rate usually needs between 15sec and 45sec to react to a change in performance and to reach its final value.
Another possibility in the ergometer test is to keep the work - the product of performance and time - constant. This is used to derive the specified marching table for the ergometer test. The heart rate is measured continuously and recorded at each level. The test is only canceled when the test person can no longer increase his or her performance. The Conconi test is mainly used in ball game sports because it can be carried out with an entire team at the same time.

The measured value pairs of heart rate and speed are entered in a diagram and evaluated: According to Conconi, the anaerobic threshold is reached at the point (deflection point) at which the linear relationship between heart rate and speed changes into a flatter curve, i.e. the curve - figuratively spoken - takes a kink down.

In the example table, when running, the speed should be increased by 0.5 km / h every 200 m. At a starting speed of 8.5 km / h, there are the corresponding times when the next 200 m mark must be reached. If the runner can no longer keep up the pace and does not reach the 200 m mark, the runner is "eliminated".
Other key performance indicators
The aerobic threshold is generally estimated to be 20 heartbeats below the anaerobic threshold. For the sake of simplicity, the aerobic threshold is usually set at a lactate value of 2 mmol / l. As a criticism, it must be noted that the processes of energy supply flow into one another and the idea of fixed thresholds for certain lactate values is no longer the current state of research.
The power that is calculated by linear extrapolation of several pairs of values measured in the submaximal intensity range for a heart rate of 170 / min is referred to as PWC 170 . The PWC 170 is no longer regarded as particularly meaningful, as is the aerobic threshold .
