Muscle strength was measured in 23 men and 29 women regarded as representative of the healthy urban population of about 80 years 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-year-old subjects ( Aniansson et al. 1980). 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 degrees/s in men. The rather low speed in comfortable walking (men 1.0 m X s-1, women 0.9 m X 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.
对23名男性和29名女性的肌肉力量进行了测量，这些人被视为约80岁健康城市人口的代表。测量了右膝伸展、跖屈和背屈的等长肌力和等速肌力，以及一些上肢功能的等长肌力。对于膝伸展，与一项针对70岁受试者的人群研究中的数值相比，力量下降了约30%（阿尼安松等人，1980年）。除了足部的跖屈和背屈外，所有肌肉群中女性的肌肉力量均显著低于男性。与较年轻年龄组相比，身体细胞质量的减少幅度与肌肉力量大致相同，并且与膝伸展和握力相关。进行了诸如台阶试验和步行试验等功能检查。除了男性在60度/秒时的膝伸展外，未发现这些试验结果与肌肉力量之间存在相关性。舒适步行的速度相当低（男性1.0米/秒，女性0.9米/秒），且爬台阶能力下降，这降低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。
