运用实验法、文献资料法和数理统计等研究方法，通过艾利尔录像解析系统对东北师范大学非体育专业25—27岁16名研究生进行自然行走时的步态测试，目的在于揭示肥胖青年和体重正常青年在自然行走过程中足底各分区着地时双支撑时期、单只撑时相、足放平的时间、步长、步宽以及不同着地时期髋、膝、踝关节角度等参数哪些存在差异部分，哪些存在着一致部分。探究运动学各项主要参数与脂肪、脂肪含量、身高、年龄等的相关性。结果表明，肥胖男青年双支撑时相、双支撑时相百分比、足放平的时间均比体质量正常男青年长，步宽比正常男青年宽，且与体质量、肥胖程度呈显著正相关，而步态周期、支撑时相与正常男青年基本一致。但肥胖青年的单只撑时相、步长均小于正常青年，且与体质量、肥胖程度呈显著负相关。足跟着地瞬间，踝关节的角度明显大于正常青年，膝关节角度明显小于正常青年，且与体质量、肥胖程度呈显著正相关。足趾离地时，肥胖青年髋关节角度大于正常青年。
運用實驗法、文獻資料法和數理統計等研究方法，通過艾利爾錄像解析繫統對東北師範大學非體育專業25—27歲16名研究生進行自然行走時的步態測試，目的在于揭示肥胖青年和體重正常青年在自然行走過程中足底各分區著地時雙支撐時期、單隻撐時相、足放平的時間、步長、步寬以及不同著地時期髖、膝、踝關節角度等參數哪些存在差異部分，哪些存在著一緻部分。探究運動學各項主要參數與脂肪、脂肪含量、身高、年齡等的相關性。結果錶明，肥胖男青年雙支撐時相、雙支撐時相百分比、足放平的時間均比體質量正常男青年長，步寬比正常男青年寬，且與體質量、肥胖程度呈顯著正相關，而步態週期、支撐時相與正常男青年基本一緻。但肥胖青年的單隻撐時相、步長均小于正常青年，且與體質量、肥胖程度呈顯著負相關。足跟著地瞬間，踝關節的角度明顯大于正常青年，膝關節角度明顯小于正常青年，且與體質量、肥胖程度呈顯著正相關。足趾離地時，肥胖青年髖關節角度大于正常青年。

By using the methods of experiment, literature review, mathematical statistics and other research methods,this thesis adopts Axial video analysis to measure the natural walking data of sixteen 25 - 27 year old non-sports major postgraduates of Northeast Normal University. The purpose is to reveal the difference between the fat young people and the normal young people when walking in the natural course of plantar.branch to the double ground support phase, alone phase, the flat feet time, step length, step width and angle of hip, knee, and ankle in different periods. The thesis also intends to find out the relationship between such indicators as fat,fat percentage, height, age, etc. The research showed that the double support phase, the percentage of double sup- pert phase and the flat feet time of the obese young male were all higher than those of the normal weight youth. The step width of obese youth was wider than the normal weight young male, and it had a noticeably positive correlation with weight and fat percentage. There was no difference in the gait cycle and support phase between the two groups. But the single support phase and step length of the obese youth were shorter than those of nor- real weight youth, and had a significantly negative correlation with weight and fat percentage. The heel ground landing moment, the ankle joint angle of the obese youth was significantly larger than that of the normal youth, and had a significantly positive correlation with weight and fat percentage. When they were lifting the ground, the ankle joint angle of the obese youth was greater than the normal youth.
