肌肉力量的测量在23名男性和29名女性被视为代表的健康的城市人口的约80岁。测量了右膝伸直、跖屈、背屈等长和等速肌力以及部分上肢功能的等长肌力。对于膝关节伸展，与70岁受试者的人群研究中的值相比，力量下降约30%。除了足底和足背屈外，女性的所有肌肉群的肌肉力量均显著低于男性。与年轻组相比，身体细胞质量的减少程度与肌肉力量相同，并与膝盖伸展和手握力量相关。进行功能检查，如台阶试验和行走试验。除了在60 °下的膝伸展之外，没有发现这些测试的结果与肌肉力量之间的相关性。s在男人。舒适步行速度较低（男子1.0米）。s-1，妇女0.9 m. cntdot. s-1）和降低的爬台阶能力减少了相对健康的老年人使用公共交通和步行街交叉口的可能性。
Muscle strength was measured in 23 men and 29 women regarded as representative of the healthy urban population of about 80 yr of age. Isometric and isokinetic strengths of right knee-extension, plantar and dorsal flexion and the isometric strength of some upper extremity functions were measured. For knee-extension there was a decrease in strength of about 30% from the values in a population study of 70-yr-old subjects. Muscle strength was significantly lower in women than in men in all muscle groups except for plantar and dorsal flexion of the foot. Body cell mass was reduced compared to younger age groups by about the same extent as muscle strength and correlated to knee-extension and hand grip strengths. Functional examinations such as step tests and walking tests were performed. A correlation between the results of these tests and muscle strength was not found except for knee-extension at 60.degree./s in men. The rather low speed in comfortable walking (men 1.0 m .cntdot. s-1, women 0.9 m .cntdot. s-1) and the reduced capacity for step climbing diminish the possibility of using public transport and pedestrian street intersections in relatively healthy old people.
