浅析表面肌电信号不同指标的数学处理与分形论的关系

Brief Analysis the Relations Between the sEMG Signal Mathematics Processing of Different Target and the Fractal Theory

运用表面肌电测试仪对江苏省女子举重队现役队员抓举的技术动作进行分析,数据统计表明,原始肌电图和以不同数据为宽幅平均化后的肌电图的图形具备自相似性,是一种分形曲线;几种肌电图的肌电信号数据是三种不同层次的分形子集,完全符合分形论的级差分形原理。

Using the myo electricity tester, the author analyzed the technique of squat snatch of the athletes in Jiangsu female weightlifting team. The results indicated that the primitive myo-electrograph and the myo-electrograph averaged by different frame width are self-similar, it is a kind of fractal curve. The sEMG signal data of those myo-electrograph are fractal subset of 3 kinds of different levels, it tallies with the theory of the grading fractal of the fractal theory.
