摘要
背景:青少年肥胖常引发扁平足、足、膝内外翻等症状。目的:了解13~15岁肥胖男生足底压力参数的分布特点,认识对青少年身体平衡能力等方面所产生的影响。方法:随机选择长春市东北师范大学附属中学13~15岁的健康在校男生60人,根据体质量指数标准分为18.5~24.9kg/m2的对照组,25~30kg/m2的超重组和大于30kg/m2的肥胖组,各20人。借助比利时footscan足底压力测试系统,分析各组自然行走时足底动态压力分布变化特征。结果与结论:不同体质量男生的足底垂直力-时间曲线的足跟着地时的冲击峰和足完全放平时出现的谷值出现在步态周期的百分比随体质量的增加而加长;超重组和肥胖组足弓部位的触地时间明显大于对照组,同时足弓和足跟的接触面积百分比增大,而前足的百分比值减小;超重组和肥胖组的足底总峰值压强明显大于对照组,足底总压强与体质量呈正相关,足底的接触面积和体质量之间存在着明显的正相关;除了足跟和第1趾骨外,超重组和肥胖组其他各部位及总的压强变化率均大于对照组。说明超重于肥胖可使男生足底压力发生变化。
BACKGROUND:Children's obesity often leads to flat feet,foot and knee introversion and extraversion.OBJECTIVE:To investigate the plantar pressure distribution characteristics in male obese children aged 13-15 years and the influences on body balance ability of adolescents.METHODS:A total of 60 school male students aged 13-15 years were randomly selected from Affiliated Middle School of Northeast Normal University.These male adolescents were assigned to three groups according to body mass index with 20 boys in each group:control group(18.5-24.9 kg/m2),overweight group(25-30 kg/m2)and obese group( 30 kg/m2).The dynamic plantar pressure distribution characteristics during natural walking were analyzed through the use of Belgium footscan planter pressure measurement system.RESULTS AND CONCLUSION:The vertical force-time curve of male adolescents with different body weights showed that the percentage of peak and valley during gait cycle increased with increasing body weight.Compared with the control group,the time of ground touching for foot arch region was significantly longer,the percentage of contact area of foot arch and heel was significantly increased,and the percentage of contact area of propodium was significantly increased in the overweight and obese groups.Total plantar pressure was significantly greater in the overweight and obese groups than in the control group.The total plantar pressure was positively related to body weight and plantar contact area was positively related to body weight.Changes in plantar pressure in each region with exception of foot heel and the first phalanx were significantly greater in the overweight and obese groups than in the control group.Results showed that overweight and obese can lead to changes in plantar pressure in male adolescents.
