Conconi Test

Synonyms in the broadest sense

Endurance test, step test,The Conconi test was developed by the Italian biochemist Francesco Conconi. The Conconi Test, like all other endurance tests, attempts to determine the anaerobic threshold at endurance stress in order to draw conclusions about endurance performance and trainability. In this test the athlete has to increase the running speed or driving speed increasingly evenly in equal intervals.

The test is therefore particularly suitable for endurance athletes at the beginning of the training phase. A further, very precise determination of the anerobic threshold is done with the lactate level test. However, this test is not completely bloodless as blood has to be taken regularly to determine the lactate level in the blood. further test: Cooper test further test:

  • Cooper’s test


Conconi assumes that the heart rate increases linearly in the aerobic zone. This range is about 100- 180 beats/minute. If the load is increased further, the curve flattens out.

This point where the curve flattens is called the deflection point and determines the anaerobic threshold. The athlete/trainer can now precisely determine the intensity (running speed/driving speed) during training. To perform the Conconi Test one needs

  • Heart Rate Monitor
  • Stop watch
  • Signal transmitter (whistle)
  • 400m train/bike ergometer
  • Paper and pen

The athlete starts with a general warm-up program.

The 400m course is divided into 2x 200m, the running speed should be chosen appropriately at the beginning of the test. Untrained athletes choose a speed of approx. 8 km/h, whereas trained athletes may well start at 12- 13 km/h.

The running speed is increased by 0.5 km/h every 200m, or the athlete runs the 200m 2 to 3 seconds faster. The trainer gives a signal at which the athlete should reach the mark (at 200m). A certain running feeling of the athlete is assumed.

Every 200m the heart rate is determined and entered in a table. Various pulse watches can store the heart rates The test is carried out until the test person can no longer increase the pace, so that at least 2 to 3 values are measured after the anaerobic threshold (up to the maximum load). The test is best performed indoors to avoid possible wind resistance.

The test person should increase the speed as constantly as possible (do not sprint the last bit to the mark). The athlete also completes a warm-up program here. The resistance at the beginning of the test should be between 25 and 100 watts, depending on the line level.

For untrained athletes, the resistance is increased by 20 watts every 2 minutes. Trained athletes increase the value by approx. 30-50 Watt. Each time the resistance is increased, the heart rate is measured and recorded.
