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).
本研究的目的是分析 30 秒 Wingate 无氧测试中距离、速度和加速度的动态变化。参与者为 53 名年轻的成年英式橄榄球运动员，平均年龄 21.6±2.5 岁，身高 180.5±7.2cm，体重 89.3±12.7kg。使用摩擦带式测功计（Monark 864，Varberg，瑞典）测量功率。个体数据根据峰值功率输出进行对齐，得出的平均值为 1216±256W，而当按横截面对比时，平均值为 1180±256W（p<0.0001）。速度和加速度的导数是使用 Mathcad 数学软件获得的。在达到峰值功率输出之前和之后，以 1s 的间隔同时绘制距离、速度和加速度曲线（-4s 至+28s）。距离曲线的初始上升是由于在达到峰值功率输出之前，正速度逐渐减小的总体趋势所致，此后由于从峰值功率输出到+28s 峰值功率输出期间负速度的出现，功率逐渐恶化。加速度曲线的初始值显示出在达到峰值功率输出之前，波动下降的负向值的趋势；随后，所有值都保持正值，沿着零加速度时间轴运行。峰值功率输出与-1s 至-3s 之间功率值之间的相关系数分别为 0.80、0.65 和 0.63（p<0.001）。速度和加速度之间的关系为-0.968（p<0.01）。
