INFLUENCE OF ANTHROPOMETRIC DIMENSIONS ON THE PREDICTION OF VO2 MAX BY STEP-TEST
Abstract
Our interest in this paper is directed toward answering this question, whether the anthropometric characteristics affect the prediction of VO2 max results obtained by step-test? The survey included 57 young athletes aged 15 to 17. The assessment of maximal oxygen consumption was determined by Astrand test on the treadmill and by step-test by von Döbeln on the stools 30cm high. The results were processed by comparative statistics methods: Spearman's correlation coefficient, Student's t-test and multiple regression analysis. The results indicate that the estimated values of maximum oxygen consumption of the respondents obtained by Astrand cycle ergometer test and the values obtained by step-test assessed by von Döbeln's formula are significantly different. The identified differences between the two tests were significantly correlated with body height, leg length, leg and body mass of the sample. Dependence among the described phenomena has been described by mathematical model, based on which it is possible to perform correction of the results of measurement and reduce the error estimates of VO2 max by 5%.References
