摘要

Dynamometric chairs were used to determine the maximum torques of the lower extremity muscles in 25- to 70-year-old males, including 106 healthy subjects and 72 patients with compensated arterial insufficiency. Thigh and calf muscle strength was significantly lower in the patients. The age-related decrease in muscle torques took place two decades earlier in the patients than in the controls. The decrease was most pronounced in the plantar flexors and was accompanied by a decrease in the transverse muscle stiffness in subjects aged over 55. The function of the dorsal flexors was virtually unchanged within the age interval from 25 to 70 years.
