title: [On-line analysis of anaerobic power and oxygen debt in rectangular-triangular stress testing (author's transl)].
abstract: The rectangular-triangular bicycle exercise test with on-line analysis of respiratory function and gas exchange is used in the evaluation of physical performance. A programme has been developed for on-line computation of an index of anaerobic power and of oxygen debt. The index of anaerobic power is calculated by subtracting the oxygen uptake exceeding the resting values from the energy demand to sustain a given work load. The oxygen uptake exceeding the resting level during a period of five minutes after the exercise test is added up and the result is taken to represent the index of the oxygen debt. In this presentation of preliminary results it is concluded that the index of anaerobic power and the parameter of anaerobic power (maximal oxygen uptake in symptom-limited stress testing) provide valuable additional information in regard to the physical performance of untrained people, athletes and patients with impaired cardio-pulmonary function in quantitative terms.
