Abstract : 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) Astrand's nomogramm, (2) the extrapolation on the upper value (195/min) and (3) the extrapolation on the lower value (180/min) 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)
