[Purpose] The purpose of this study was to examine the fall-prevention effect of 12 weeks of aquatic training for the elderly using variables representative of the relationship between the trailing foot and an obstacle. [Subjects] Ten healthy elderly participants, who lived in C city, (age: 77.15±5.21 yrs, height: 149.87±3.54 cm, body mass: 57.44 ±6.74, and BMI: 25.58±2.98 kg/m(2)), participated in this study. [Methods] To determine the effect of 12 weeks' aquatic training, 3-D motion analysis with 7 infrared cameras and one force plate, was performed. [Results] TC, HC, MVHC, and CV significantly increased after intervention. For the all gait stability parameters, statistically significant training effects were found. [Conclusion] In conclusion, 12 weeks' aquatic exercise can help the elderly become more stable when crossing a height obstacle, which is the most frequent cause of falls by the elderly.
[目的]本研究旨在通过代表后脚与障碍物之间关系的变量，检验为期12周的水上训练对老年人预防跌倒的效果。[对象]10名居住在C市的健康老年人（年龄：77.15±5.21岁，身高：149.87±3.54厘米，体重：57.44±6.74，体重指数：25.58±2.98千克/平方米）参与了本研究。[方法]为确定12周水上训练的效果，使用7台红外摄像机和1个测力台进行了三维运动分析。[结果]干预后，步幅时间、步幅长度、平均步幅长度和步幅速度显著增加。对于所有步态稳定性参数，均发现了具有统计学意义的训练效果。[结论]总之，为期12周的水上运动可以帮助老年人在跨越高度障碍物时更加稳定，而高度障碍物是老年人跌倒的最常见原因。
