Developing the Estimating Equations for Muscle Power by Analysis of Reliability and Validity on Different Versions of Wingate Anaerobic Test Setting

Abstract

PURPOSE The purpose of this study was to develop the estimating equations for 4 types of Wingate Anaerobic test setting.METHODS 80 male elite athletes performed 4 trials of the Wingate Anaerobic test by each type. Subjects were conducted the retest one week later. Data collected from the Wingate Anaerobic test included mean power, peak power, and power drop for 30s were measured. Coefficient of correlation was used for validity of type 1(DOS version) and the other types(ver. 2.24, 3.3.0, and 3.2.1). Pearson’s correlation coefficient was used to examine the reliability of test and retest. Simple regression analysis was used for calculating the estimating equation.RESULTS There was significant correlation for absolute value(Watt, p<.01) and relative value(Watt/kg, p<.01) of mean power, absolute value(W, p<.01), relative value(Watt/ kg, p<.05), and power drop rate(%, p<.01). Test and retest reliability was excellent for all test variables(p<.01).CONCLUSIONS From the all results, the estimating equation was calculated to convert all outputs from each type to the other types of the Wingate Anaerobic test setting. These findings suggest that the estimating equations are compatiable to 4 types of Wingate Anaerobic test setting.
