[Comparative measurements of PWC170 with work steps of different load increase and duration (author's transl)].

The "Physical Working Capacity" (PWC170) which has been shown to be an ergometric method for determination of the physical performance is due to measurement of heart rate during physical work under steady-state conditions. However the practical application of those methods of multiple work steps of six minutes is limited due to the time-consuming procedure. Therefore, we measured in 30 test-persons PWX170 with work-steps of 50 Watt/6 min. in comparison with 25 Watt/2 min. The difference between these two test-series of 3.7% was not significant. For daily determination of PWC170 the more time-saving procedure with work steps of 25 Watt/2 min. is suggested.
