Aging Effects on the Elderly Walking : a Longitudinal Study

对居住在该社区的健康老年人进行了7年的纵向研究，每半年重复一次，在夏季和冬季重复一次。分析了老年人步行的特点及其随年龄的变化，并与青壮年的步行进行了比较。在许多测量中都观察到了季节性差异。在同一季节进行比较时，握力和髋关节活动度随着年龄的增长而显著下降。骨密度和脂肪比例也有下降。相比之下，重复训练组的步行速度有所提高。培训将导致这一增长。

Normal walking of healthy elderly people living in the community was longitudinally studied during seven years repeatedly every one half year in summer and winter seasons. Characteristics of elderly walking and their changes according to the age were analyzed including the comparison with those of young adults. Seasonal differences were observed in many measurements. Significant decreases along with the age were observed in the grip strength and the range of hip joint when comparisons were made in the same season. Decreases were also observed in the bone density and the fat proportion. By contrast, the walking speed increased in the repeated group. The training will result in the increase.
