拉丁舞不同舞种足底压力动态分布特征研究

A Research on the Distribution Characteristics of Plantar Pressure in Different Kinds of Latin Dance

研究采用比利时Footscaninsole 2.39测力鞋垫对优秀拉丁舞运动员进行测试,从足底压力中心轨迹、足底压强曲线、脚底各个分区的压强峰值和压强峰值时相五个方面探讨拉丁舞不同舞种足底压力动态分布特征。研究发现伦巴、恰恰恰和桑巴舞运动中的足底压力中心轨迹呈现出由内侧往足中部经一拐点后往外侧上方移动的规律,且压强曲线为双峰曲线,牛仔舞的为单峰曲线;拉丁舞运动时力集中在前足内侧跖骨区,足跟和足外侧跖骨区所承受压力较小;不同舞种足底压强峰值时相呈现一定的规律。

This paper makes measurement and analysis on force distribution of foot for several outstanding Latin dancers by using the Footscan insole 2.39（force-measuring insoles）,discusses the distribution characteristics of plantar pressure in different kinds of Latin dance in foot center of pressure trajectory,the curve of plantar pressure,foot peak pressure of each partition and the proportion of time pressure when peak occurs.The result shows rumba,cha cha cha and the samba movement in the center of pressure trajectory from the plantar foot medial to the middle by an inflection point,and then moving upside;Plantar foot pressure curve shows a single peak curve of left foot and double-peak curve of the right one;Force concentrated on the former medial metatarsal area and less pressure in lateral heel and metatarsal area of foot during Latin dance movement;Peak plantar pressure of different kinds of dance shows a certain degree of law of chronological order.
