The maximal oxygen uptake of 19 untrained young males 21--28 years was measured by stepwise increase of exercise on a bicycleergometer direct method. The maximal oxygen uptake was estimated by different indirect methods, using the well-known linear relationship between heart rate and oxygen uptake 1 Astrands nomogramm, 2 the extrapolation on the upper value 195min and 3 the extrapolation on the lower value 180min of the maximal heart rate given in literature for comparable groups. The individual deviations in the results obtained with the direct and indirect methods ranged from plus 19 to minus 18. Author
