采用Footscan足底压力测量系统对197名年龄在7~13岁之间的女童进行动态足底压力测试,有效样本数为178例。将受试儿童按照不同年龄段分为非肥胖组(组1)和肥胖组(组2),分析各年龄段两组女童的动态足底压力特征,研究结果表明:(1)各年龄段肥胖组的足底压强峰值、压强时间积分、压力峰值以及冲量均大于非肥胖组,且显著性差异均集中在第2~5跖骨区域、中足区域以及后跟区域;(2)各年龄段肥胖女童的压强变化率较大,表现为机体平衡性能较差;(3)随着体质量的增长,各年龄段女童的足底压力随之增大,但并无随年龄变化的明显规律。
Footscan plantar pressure measuring system was used to test the dynamic plantar pressure of 197 girls between the ages of 7 and 13 years. The effective sample number was 178. The subjects were divided into non-obese group (group 1) and obese group (group 2) according to different age groups. The dynamic plantar pressure characteristics of the two groups were analyzed. The results showed that: (1) obesity The peak of plantar pressure, time integral of pressure, peak pressure and impulse of pressure group were greater than those of non-obese group, and significant differences were found in metatarsal area 2 to 5, midfoot area and heel area. (2) Obese girls (3) With the increase of body mass, the plantar pressure of girls in all age groups increased with the increase of body weight, but there was no obvious regularity with age.
