Abstract/OtherAbstract:
The purpose of the present study was to analyse the dynamics of distance, velocity and acceleration of the 30-s Wingate Anaerobic Test. Participants were 53 young adult Rugby Union football players of mean age 21.6±2.5 yr, 180.5±7.2 cm height and 89.3±12.7 kg body mass. Measurements of power were obtained using a friction-belt cycle ergometer (Monark 864, Varberg, Sweden). Individual data were aligned according to peak power output, which resulted in a mean value of 1 216±256 W, compared with one of 1 180±256 W when calculated cross-sectionally (p<0.0001). The derivatives of velocity and acceleration were obtained using the mathematical software Mathcad. Distance, velocity and acceleration curves were plotted simultaneously at 1 s intervals before and after peak power output (-4 s to +28 s). The initial rise of the distance curve was the result of a general trend in decreasing positive velocities as far as peak power output, followed thereafter by a gradual deterioration of power, the result of negative velocities from peak power output to +28 s peak power output. The initial values of the acceleration curve showed a fluctuating decelerating trend of negative values to peak power output; subsequently all values remained positive running along the zero acceleration time axis. Coefficients of correlation between peak power output and power values at -1 s to -3 s were 0.80, 0.65 and 0.63 respectively (p<0.001). The relationship between velocity and acceleration was - 0.968 (p<0.01).
