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。将受试女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: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;各年龄段肥胖女童足底的压强变化率较大,表现为机体平衡性能较差;随着年龄的增长,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 measurement system was used to test the dynamic plantar pressure of 197 girls aged 7-13 years. The effective sample size was 178 cases. The girls 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 of girls in each age group were analyzed. The results showed that: the peak pressure of plantar pressure, the time integral of pressure, the peak pressure and the impulse of obesity in all age groups were higher than those in non-obese group, and the significant differences were all found in the second to fifth metatarsal area, midfoot area and heel area ; The change rate of pressure on the soles of obese girls in all age groups was larger, which showed that the body balance performance was poor. As the age increased, the plantar pressure of girls in all age groups increased, but not obvious with age law.
