摘　　要：为了准确评估武术运动员对特定动作姿势控制的平衡性,提出了一种基于Higuchi分形维数分析的平衡性评估方法 .首先,通过力测试平台获得运动员做出特定动作时的足底压力中心(COP)数据,构建一个时间序列.然后,通过Higuchi算法计算该时间序列在自前而后和自内而外两个方向上的分形维数(FD).最后,根据分形维数值来评估动作姿态的平衡性.专业和业余运动员的对比实验结果表明,该方法比传统方法能更准确地反映动作的平衡性.In order to accurately evaluate the balance of the martial arts athlete＇s control over the specific posture,a balanced evaluation method based on Higuchi fractal dimension analysis is proposed.Firstly,a force test platform is used to acquire the center of pressure（COP）data when the athlete makes a specific postural to construct a time series.Then,the fractal dimension（FD）of the time series in the anterior-posterior and medial-lateral directions is calculated by the Higuchi algorithm.Finally,the balance of the posture is evaluated based on fractal dimension values.The results of comparative experiments conducted by professional and amateur athletes show that the method can more accurately reflect the balance of movement than traditional methods.
