基于动力学数据采集和分析，明确了速度滑冰冲刺（直道）阶段的蹬冰力。采用Novel pedar-X足底压力分布测量系统（传感器数量99个/只）进行运动员足底压力的测量，数据采集频率30Hz。取蹬冰力/体重的比值进行了蹬冰力/体重的标准化处理。然后，使用Butterworth 4阶低通滤波方法对蹬冰力数据进行低通滤波，截止频率为15.0Hz。同时，使用Matlab R2022a对时间进行归一化处理，得到了速度滑冰冲刺（直道）阶段的蹬冰力。

Based on the kinetic data collection and analysis, the stirring force during the sprint (straight) phase of speed skating was determined. A Novel pedar-X plantar pressure distribution measurement system (99 sensors/unit) was used to measure the plantar pressure at a frequency of 30 Hz. The ratio of stirrup force/body weight was normalized to the stirrup force/body weight. Then, a Butterworth 4th-order low-pass filter was used to low-pass filter the force data with a cut-off frequency of 15.0 Hz, and Matlab R2022a was used to normalize the time to obtain the force during the sprint (straight) phase of speed skating.
