Developing the activity program in day service center based on the functional characteristics of older people

为在老年服务中心开展活动项目收集资料，根据老年人的功能特点，进行了以下一系列研究：1)对426名0岁以上的男性和女性的最大伸膝肌力或最大伸膝肌力与日常生活活动程度的关系进行了研究。伸膝肌力或力量的下限，男性应高于14W/kg或1.0 kg/kg，女性应高于9W/kg或0.8 kg/kg。在健康的受试者中，肌肉力量输出与跌倒体验并不一定相关。2)比较了5名健康的女性和30名年龄在57-92岁的体弱男女从椅子上站起来的动作。躯干前倾程度、髋关节和膝关节屈曲角度的变化在虚弱老年人中显著增大。虚弱老年人的步行速度、伸膝力量与步态成绩之间存在显著的相关性，而静态平衡能力与其相关性不显著，需要进一步的研究，特别是在低适合度的老年人中，阐明年龄和身体素质对老年人日常生活活动的运动特征的影响，并制定合适的方案。

To collect the data for developing the activity program in the elderly thy service center based on the functional characteristics of older people a series of study was performed as follows ;1) Maximal knee extension muscle strength or power, and its relation to the degree of activities of daily living were examined in 426 men and women aged over G0years old.a. The lower threshold of knee extension muscle strength or power might be supposed to be above 14W/kg or 1.0kg/kg for men and 9W/kg or 0.8kg/kg for women.b. In fitted subjects muscle power output isn't necessarily related to the fall experience.2) The motion of rising from a chair was compared between 5 fitted women and 30 frail men and women aged 57-92 years old.a. The degree of trunk forward lean, the joints angle change of hip and knee flexion were significantly larger in frail elderly.b. Maximal knee extension muscle strength was significantly related to small postural change during rising from a chair, and frail elderly people showed some difficulties for rising from lower chair.c.In frail elderly there was significant relationship among walking velocity, knee extension strength and stepping performance, while static balancing ability did not do so.Further research, especially in low fitted elderly subjects, should be needed to clarify the effects of age and physical fitness on the motion characteristics of the activities of daily living in the elderly, and to develop a suitable program.
