Laboratory exercise testing in athletes is based on aerobic and anaerobic tests. In general, aerobic exercise tests are time consuming and demand for highly sophisticated equipment, e.g. gas analysers and ventilometers that should be precisely calibrated. Contrary to this, anaerobic exercise test are usually less time consuming and based on relatively simple principles. The aim of the study was to verify the possibility to predict the main parameters of aerobic tests from the results of anaerobic exercise test, i.e. 30-s Wingate test. Methods Altogether 152 top league ice-hockey players (age: 25.96 +/- 4.72 (SD) years; mass: 87.73 +/- 8.17 kg; height: 182.4 +/- 5.7 cm) participated in the study. They were examined at the end of preparatory period before the season. In the same day they were tested by a 30-s Wingate test at a resistance 6 W.kg-1 (=0.104 kg.kg-1), and after 2-hour-lasting recovery break they were loaded by the stepwise maximum cycle ergometry. The statistics included multiple stepwise linear regression analysis using SPSS statistical package. Age, body mass, height, fat-free mass, and Wingate test results were considered independent variables whereas maximum aerobic power (VO2max) and maximum power were considered dependent variables. As peak blood lactate concentration (LA) in the Wingate test is sometimes (but not as a standard) included to the results of the Wingate test, the results were computed both with and without LA as an independent variable. Results Pmax [W] = 351.227 + 0.322*Pmin [W] - 2.867*MP/PP [%] + 0.880*Age [y] r= 0.685; SEE= 25.159; sign. 2.976E-20 Pmax/kg [W.kg-1] = 9.016 - 0.055*Body mass [kg] - 0.004*Pmin [W] - 0.039*MP/PP [%] + 0.012*Age [y] r= 0.694; SEE= 0.287; sign. 3.559E-20 VO2max [l.min-1] = 0.487 + 0.003*Pmin [W] + 0.015*Body mass [kg] + 0.053*LA [mmol.l-1] r= 0.662; SEE= 0.372; sign. 1.750E-18 VO2max [l.min-1] = 1.375 + 0.003*Pmin [W] + 0.015*Body mass [kg] r= 0.641; SEE= 0.380; sign. 7.453E-18 VO2max/kg [ml.kg-1.min-1] = 36.437 + 2.935*Pmin/kg [W.kg-1] - 0.166*Body mass [kg] + 0.603*LA [mmol.l-1] r= 0.539; SEE= 4.301; sign. 4.972E-11 VO2max/kg [ml.kg-1.min-1] = 47.670 + 2.797*Pmin/kg [W.kg-1] - 0.174*Body mass [kg] r= 0.506; SEE= 4.388; sign. 2.621E-10 Discussion Regardless the substantial differences in the nature of the aerobic cycle ergometer test and anaerobic Wingate test the results had demonstrated the possibility to predict the parameters of aerobic tests from the results of the 30-s Wingate test. The standard errors of the estimate obtained form these equation seem to be considerably low and therefore acceptable, however coefficients of correlation (r) ranging 0.506 to 0.694 and/or coefficient of determination (R2) 0.256 to 0.482 may limit the predictive validity of VO2max and Pmax from the Wingate test results.
