本研究的目的是利用等式结构模型，探讨随着年龄的增长，行走能力的下降是由于肌肉萎缩所致的假说，以及肌肉对行走能力的影响。研究对象为127名年龄在20-84岁之间的男童(男57名，女70名)，年龄分为6个年龄段，20岁至39岁，40岁至49岁，50岁至59岁，60岁至69岁，70岁至74岁，75岁以上。用MRI测量腰大肌和大腿肌(分为伸肌和屈肌)的横截面积。对于行走模式，每个受试者以正常速度沿着一条7米长的步行通道行走，以便用录像机记录运动。得到的图片被用来分析步幅、躯干倾斜度和行走速度。与20~39岁年龄组相比，男性50‘S年龄组和女性60’S年龄组步行速度值有统计学意义的下降(P
The purpose of this study was to investigate the hypothesis that the reduction in walking ability is due to muscle atrophy in the lower limb muscles with aging using equational structure modeling as well as investigate the influence of muscle on walking ability. The subjects consisted of 127 per sons (57 males and 70 females) aged 20 similar to 84 year, who were grouped into 6 age brackets of 20 similar to 39, 40 similar to 49, 50 similar to 59, 60 similar to 69, 70 similar to 74, and 75 or older. Using MRI, muscle cross-sectional area was measured on psoas major and thigh muscle (divided into extensor and flexor). For walking patterns, each subject walked along a 7-m walking passage at normal speed for VTR-recording of the motion. The resulting pictures were used to analyze stride length, trunk inclination and walking speeds. Walking speeds showed a statistically significant decrease in value from the 50's age group in males and the 60's age group in females when compared with the 20 similar to 39 age bracket (p
