项目摘要

Purpose : To assess the relationship between occlusal status, movement of the body's center of gravity(MBCG) and sports abilities of children. 116 children, aged 3-5years old, were surveyed in 2001 and 2002. Their occlusal status, occlusal contact area, and bite force were measured by biting on a Dental Prescale film and analyzed using the Occluzer (FPD-705 Fuji Film Co., Japan). An automatic analysis system for posture (VTS-311 EGG 2000v, Patella Co., Japan) was used to measure MBCG. 25-meter running activity, distance of throwing a ball and distance of standing board jump were tested and checked for correlations with occlusal status.Results : The mean occlusal contact was 6.3, 9.0, 10.3mm^2 by age group (3, 4, 5years old) and bite force was 242, 345, 374N, MCGB with opened eyes15.1, 11.2, 9.1cm^2, MCGB with closed eyes 17.1, 14.0, 12.3cm^2. In the 25-meter running activity, 8.9, 6.9, 6.1 sec, distance of throwing a ball 4.1, 5.5, 6.1m, the formation rate of the arch of the foot, 33.3, 37.2, 73.7%, the standing board jump 57.5, 84.0, 98.5cm respectively. There were significant differences in physical abilities and MBCG between age groups. Occlusal contact area, bite force, MBCG and sports abilities were significantly increased inter age, but not significantly different infra age between the formation rate of the arch of the foot and occlusal contact area, bite force and sports abilities. 61 children (3-5 years old) were surveyed on May and November in 2003. The MCGB and the formation rate of the arch of the foot were developed in the latter compared to the former. But the group of the formation rate of the arch of the foot was not significantly different.Conclusion : The study showed that physical development was related with bite force, MBCG and the formation rate of the arch of the foot.

目的：评估咬合状态，身体重心（MBCG）的运动与儿童运动能力之间的关系。在2001年和2002年对116岁的3-5岁儿童进行了调查。他们的咬合状态，咬合接触面积和咬合力是通过咬在牙科预定膜上测量的，并使用accluzer（FPD-705 Fuji Film Co.，日本，日本）进行了分析。用于姿势的自动分析系统（VTS-311 EGG 2000V，日本帕特拉公司）测量MBCG。测试并检查了25米的跑步活动，投掷球的距离和站立板跳高的距离，并检查了与咬合状态的相关性。退回：平均咬合接触为6.3、9.0、10.3mm^2按年龄组（3、4、5年龄），咬合力为242、345、345、374N，MCGB与Open Eight Eight Eight Eigned Eighted Eighted Eighted Eight Eigned Eignc.1.2，11.2.2眼睛17.1，14.0，12.3cm^2。在25米的跑步活动中，8.9、6.9、6.1秒，投掷球4.1、5.5、61M的距离，脚拱的构造速率为33.3、37.2、73.7％，常驻板跳高57.5、84.0、98.5厘米。年龄组之间的身体能力和MBCG存在显着差异。咬合接触面积，咬合力，MBCG和运动能力显着增加，但在脚拱的形成率和咬合接触区域，咬合力和运动能力之间并没有显着差异。 2003年5月和11月对61名儿童（3-5岁）进行了调查。与前者相比，MCGB和脚拱的形成率是在后者的。但是，脚拱的形成速率组没有显着差异。判断：研究表明，身体发育与咬合力，MBCG和脚拱的形成率有关。
