选择5款速滑冰刀（黑龙T型钛合金冰刀、枫叶双极光冰刀、海盗蓝宝石冰刀、海盗银武士冰刀、EVO镂空白管冰刀）作为测试冰刀，对冰刀上的品牌和其他有辨识度的特征进行遮挡处理。将表面肌电电极粘贴于双侧臀大肌、双侧股二头肌、双侧股四头肌外侧头、双侧股直肌、双侧股四头肌内侧、双侧腓肠肌内侧头、双侧胫骨前肌。16名运动员按6个阶段（起跑、直线、入弯、弧顶、出弯、冲刺）分别使用5款速滑冰刀进行500米测试。肌电的原始信号采用带通滤波进行处理，滤波器范围为8～500Hz，并计算左右腿蹬冰滑行过程中的积分肌电值(IEMG)、均方根振幅(RMS)。然后分别对6个阶段中4个时刻（左右脚触冰、左右脚离冰）的表面肌电参数进行统计学分析。

Select 5 types of speed skating skates (Black Dragon T-shaped titanium alloy skates, Maple Leaf Double Aurora skates, Pirate Sapphire skates, Pirate Silver Warrior skates, and EVO Hollow White Tube skates) as the test skates to mask the brand and other recognizable features on the skates. Apply surface electromyography electrodes to bilateral gluteus maximus, bilateral biceps femoris, bilateral lateral head of quadriceps femoris, bilateral rectus femoris, bilateral medial head of quadriceps femoris, bilateral medial head of gastrocnemius, and bilateral anterior tibial muscles. Sixteen athletes were tested for 500 meters using five types of speed skating ice skates in six stages (starting, straight, entering, arc top, exiting, and sprint). The original EMG signal is processed using a bandpass filter with a filter range of 8 to 500 Hz, and the integrated EMG value (IEMG) and root mean square amplitude (RMS) during left and right leg ice skating are calculated. Then, statistical analysis was conducted on the surface electromyographic parameters at 4 times of the 6 stages (left and right feet touching the ice, and left and right feet leaving the ice).
