| Research Abstract |
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.
