目的：按年龄和种族/民族描述美国老年男性和女性的等速膝关节伸肌力量，并确定其与标准的关系。定时步行速度测试。设置：美国国家健康和营养检查调查(NHANES)1999-2000。设计：一项具有全国代表性的横断面健康检查调查。样本：所有50岁及以上的受调查者(N=1,499)，他们在NHANES流动检查中心进行了肌力和定时步行检查。测量：膝关节伸肌的向心峰值扭矩(力量)以1.05拉德/S(-1)的速度和6米步行的速度计时。结果：膝关节伸肌力量与年龄呈负相关(P
OBJECTIVES: To describe isokinetic knee extensor muscle strength in older U.S. men and women by age and race/ethnicity and to ascertain its relationship to a standard, timed walking-speed test.SETTING: The U.S. National Health and Nutrition Examination Survey (NHANES) 1999-2000.DESIGN: A cross-sectional nationally representative health examination survey.PARTICIPANTS: All surveyed persons aged 50 and older (N=1,499) who performed muscle strength and timed walk examinations in the NHANES mobile examination center.MEASUREMENTS: Concentric peak torque (strength) of the knee extensors at 1.05 rads/ s(-1) velocity and a 6-m walk timed in seconds.RESULTS: Knee extensor strength was inversely associated with age (P
