Aim. The aim of the present study was to compare estimated values of maximum O2pulse obtained from three indirect exercise methods with those obtained from the equation (none exercise method) proposed by Jones et al. in athletic girls.
Methods. For this purpose, 28 athletic girls with a mean (Standard Deviation) age, weight and height of 22±1 years, 57.3±6.63 kg and 162.52±3.85 cm, respectively were randomized to participate in this research. To predict the maximum O2pulse the subjects performed three exercise tests: 1-mile track walk test, peak power output cycle ergometer test and the Siconolfi step test. The values obtained from the three exercise tests were then compared with Jones’s predictive criterion protocol.
Results. The 1-mile track walk test and the peak power output cycle ergometer test revealed objective prediction of maximum O2pulse (14.58±1.37 mL/beat, P=0.345, 14.55±1.39 mL/beat, P=0.572) and showed no significant difference with the Jones protocol. However, the Siconolfi step test (13.06±2.47 mL/beat, P=0.001) significantly differed (with regard to overestimate, under estimate) from Jones protocol.
Conclusion. These results suggest that the maximum O2pulse, as a variable indicator of cardiopulmonary efficiency, is predicted more objectively by 1-mile track walk test and peak power output ergometer test than by the Siconolfi step test, so that the values of O2pulse max resulted from this two tests are very close to Jones’s values and, therefore, these two exercise tests can be used considerably for the prediction of maximum O2pulse in athletic girls.
