Maximal muscle strength and blood flow of the femur in elderly were measured. Thereafter, they were divided into 2 groups: the low- or high-speed walking group and continued 30-min walking for 4 weeks. There was a correlation between muscle endurance strength and blood flow, irrespective of the age. The high-speed walking group showed greater increase in both muscle endurance strength and blood flow than the low-speed walking group. The older subjects showed greater decrease in muscle endurance strength and blood flow, whereas those in the high-speed walking group showed greater improvement in muscle endurance strength and blood flow. It is concluded that the muscle endurance strength and blood flow are improved by high-speed walking, irrespective of the age.

对老年人股骨最大肌力和血流量进行了测定。之后，他们被分为2组：低速或高速步行组，并继续步行30分钟，持续4周。肌肉耐力强度和血流量之间存在相关性，与年龄无关。高速步行组在肌肉耐力和血流量方面的增加均大于低速步行组。老年受试者的肌肉耐力和血流量下降幅度更大，而高速步行组的受试者的肌肉耐力和血流量改善幅度更大。结论：无论年龄大小，高速步行均能提高肌肉耐力和血流量。
