| 摘 要： | 通过对上海、南京、芜湖3城市l,226名60-97岁老年人与日常生活活动(ADL)的调查,测试了城市老年人肌力变化特点,分析肌力变化与ADL的关系.结果表明:城市老年人肌力随年龄增长而下降,男女性分别在80岁和75岁之后下降幅度增大;肌力下降将给老年人ADL带来不良影响;以反复坐起试验(RCS)时间=9.0秒表示肌力下降的临界值较合理,此时灵敏度为O.88,特异度为0.60.为了防止老年人肌力下降影响老年人日常生活活动能力,需要有针对性地在老年人体育锻炼中增加力量练习的比重.

| Abstract: | The purpose of this study is to investigate changes in muscle strength and its effects on activity of daily living(ADL) in the elderly living in three Chinese cities(Shanghai,Nanjing and Wuhu).A total of 1,226 urban residents ranging from 60 to 97 in age are included in this study and grip strength,Repeated Chair Stands(RCS) test are conducted,a questionnaire is conducted to investigate their ADL and a Receiver Operating Characteristic curve(ROC) is used to identify the demarcation point of marked muscle strength decline.Research findings show that muscle strength of the urban elderly drops with age increase and the declined muscle strength has an unfavorable effect on ADL.Given a demarcation point of 9.0 seconds in RCS test,sensitivity is 0.88 and specificity was 0.60.The study suggests that corresponding muscle strength training programs should be strengthened in sports exercises for the elderly to hamper the bad effect of declined muscle strength on ADL. |
