【摘要】：为了阐明3岁至6岁健康儿童跑步步态特征,为幼儿动作发展过程和促进幼儿健康成长提供理论依据。采用二维摄像和录像解析的方法,对3岁至6岁儿童跑步进行拍摄,然后进行分组分析,通过对相邻年龄间比较以及同年龄不同性别比较发现,性别因素对幼儿的跑步步态特征影响不显著,相邻年龄组之间步态特征呈现显著差异。幼儿着地运动学特征与成人存在差异,幼儿在缓冲起始阶段,蹬伸末段的关节角度四岁以后表现出接近成人的稳定状态。5幼儿在腾空阶段,髋、膝关节有明显随年龄增大的趋势,踝关节在四岁前五岁后有明显变化差异。
[Abstract]:In order to elucidate the running gait characteristics of healthy children aged 3 to 6 years, and provide theoretical basis for the development of children's movements and promote the healthy growth of young children, two dimensional camera and video analysis methods were used. The children aged from 3 to 6 years old were photographed for running and then analyzed in groups. The results showed that the gender factors had no significant influence on the running gait characteristics of children by comparing the adjacent ages as well as the same age and gender. There were significant differences in gait characteristics between adjacent age groups. There were differences between children landing kinematics and adults, and children were in the buffer initial stage. The angle of joint at the end of pedal and extension showed a stable state close to that of the adult after 4 years old. 5. The hip and knee joint showed a trend of increasing with age in the empty stage, and the ankle joint had a significant change after the age of five years before the age of 4 years.

【正文快照】： 跑步是幼儿在日常生活中最常见的基本动作之一,同时也是锻炼幼儿身体的手段之一。跑的发展不仅影响儿童少年的运动能力,而且对他们未来体质的强弱、运动能力的高低都有着重要的影响。因此国内外体育科研和教学机构都把儿童不同时期跑的发展作为重要的研究课题[1-3]。跑步运动
