[Estimation of the performance spectrum of healthy adolescents by using the PWC 170 (Physical Work Capacity)]

On 10 persons we performed maximal rectangular-progressive bicycle-test, with measuring of VO2max and maximal work in Watts (Wmax), including the working time at the last step. In 18 other young people, we all together made 29 tests without spirometry. In addition to Wmax, the PWC 170 was figured out, once with two higher ergometer steps and once with two lower steps. We found a high correlation between Wmax and VO2max on the one side and PWC 170 and Wmax on the other. If, for the PWC 170 will be utilized, two steps with heart-rates of greater than 140 on the lower and 160 to 170 on the higher step, the PWC 170 seems to be exactly sufficient for estimating the maximal physical working capacity for routine testing of healthy young people.
