Allometric Scaling of Wingate Anaerobic Power Test Scores in Men

Abstract

This study examined the appropriate magnitude of allometric scaling of the Wingate anaerobic test (WAnT) power data for body mass (BM) and established normative data for the WAnT for adult men. Eighty-three men completed a standard WAnT using 0.1 kg·kg(-1) BM resistance. Allometric exponents and percentile ranks for 1-second peak power (PP), 5-second PP, and mean power (MP) were established. The Predicted Residual Sum of Squares (PRESS) procedure was used to assess external validity while avoiding data splitting. The mean 1-second PP, 5-second PP, and MP were 1,049.1 ± 168.8 W, 1,013.4 ± 158.6 W, and 777.9 ± 105.0 W, respectively. Allometric exponents for 1-second PP, 5-second PP, and MP scaled for BM were b = 0.89, 0.88, and 0.86, respectively. Correlations between allometrically scaled 1-second PP, 5-second PP, and MP, and BM were r = -0.03, -0.03, and -0.02, respectively, suggesting that the allometric exponents derived were effective in partialling out the effect of BM on WAnT values. The PRESS procedure values resulted in small decreases in R² (0.03, 0.04, and 0.02 for 1-second PP, 5-second PP, and MP, respectively) suggesting acceptable levels of external validity when applied to independent samples. The allometric exponents and normative values provide a useful tool for comparing WAnT scores in college-aged females without the confounding effect of BM. It is suggested that exponents of b = 0.89 (1-second PP), b = 0.88 (5-second PP), and b = 0.86 (MP) be used for allometrically scaling WAnT power values in healthy adult men and that the confidence limits for these allometric exponents be considered as 0.66-1.0 for PP and 0.69-1.0 for MP. The use of these exponents in allometric scaling of male WAnT power values provide coaches and practitioners with valid means for comparing power production between individuals without the confounding influence of BM.

Bilateral Knee Joint Cooling on Anaerobic Capacity and Wheel Cadence during Sprint Cycling Intervals

“…Our sample size was calculated based on the primary dependent measurement, the anaerobic capacity of cycling sprint (watt/kg). In a similar ergometer test, the average values on healthy adults were between 8 and 10 watt/kg [ 10 , 11 ]. To detect a difference of 2.1 watt/kg with a standard deviation of 2.0 watt/kg (an effect size of 1.0 using an alpha of 0.05 and a beta of 0.2), a minimum of 16 subjects was necessary.…”

Single and combined effect of kinesio tape and warm-up on sprint cycling performance

“…The PP and AP were scaled using allometric exponents by the log-linear regression approach. The equation y = a × body mass -b (y: PP and AP normalized; a: PP or AP not normalized; b: constant) [ 19 ]. The normality of data distribution was assessed by the Shapiro-Wilk’s Normality Test.…”
