基于COP的太极桩功足底压力特征提取及分析
COP-based Feature Extraction and Analysis of Plantar Pressure in Tai Chi Stake
摘要
Abstract
To explore the inherent characteristics of Tai Chi Stake training and digitally interpret its movement es-sentials,an effective plantar pressure detection equipment was used to collect plantar pressure signals from partici-pants,and the relative position,time-domain,frequency-domain,and regularity indicators of the center of pressure(COP)movement between the expert group and the trainee group were compared and analyzed.The results showed that the relative position of COP of the expert group was closer to 50%compared to the trainee group.In terms of time-domain indicators,the root mean square of COP movement of the expert group was significantly larger than that of the trainee group in both the left-right and front-back directions,while the frequency-domain peak frequency of the movement was significantly lower than that of the trainee group in both directions.For the sample entropy anal-ysis of COP that measured the regularity,the expert group showed significantly lower values in both the left-right and front-back directions compared to the trainee group.The Tai Chi Stake COP of the expert group was more concentrat-ed in the central position,reflecting the technical essential of"stand straight and be centered".The regular low-fre-quency adjustment reflected the characteristic of"motion in quiescence"in Tai Chi Stake.关键词
