Postural sway behavior while standing and during and after an unexpected disturbance of balance was examined in men aged 31 to 35, 51 to 55, and 71 to 75 years. The groups studied were random samples of men living in the town of Jyväskylä in 1981. Postural sway while standing was more pronounced in the older age groups, whereas after a disturbance of balance postural sway was nearly the same in all age groups. The functioning of the postural control system was correlated with the vibratory threshold on the ankles, grip strength, as well as with aerobic and anaerobic capacity within the age groups. Further, in the youngest age group the functioning of the postural control system was poorer among those who had been subject to noise at their work. The correlation between health status and postural sway was negligible. The results may indicate the partly parallel and similar effects of aging, poor physical fitness, and harmful environmental factors on the functioning of the postural control system.
对年龄在31至35岁、51至55岁和71至75岁的男性在站立时以及平衡受到意外干扰期间和之后的姿势摇摆行为进行了研究。所研究的群体是1981年居住在于韦斯屈莱镇的男性随机样本。站立时的姿势摇摆在年龄较大的群体中更为明显，而在平衡受到干扰后，所有年龄组的姿势摇摆几乎相同。姿势控制系统的功能与脚踝的振动阈值、握力以及各年龄组内的有氧和无氧能力相关。此外，在最年轻的年龄组中，工作中接触噪音的人群姿势控制系统的功能较差。健康状况与姿势摇摆之间的相关性可忽略不计。结果可能表明衰老、身体素质差和有害环境因素对姿势控制系统功能的部分平行且相似的影响。
