Research Abstract

It is well known that regular physical activity prevents the decline of exercise capacity with aging. However, it is unclear whether this benefit is true for elderly people over 80 years of age. The purpose of this study was to identify the physiological characteristics of elderly subjects who possessed high exercise performance.
The subjects were elderly elite athletes ranging in age from 80 to 86 years. All eldely athletes had trained for long periods and participated in national and international sports competitions in various events. Some eldely athletes held the world records in master events. The isokinetic strength, femoral cross-sectional area (CSA), maximal oxygen uptake (VOィイD22ィエD2max), bone mineral density and fitness level were measured in all eldely athletes.
The isokinetic strength for both knee extension and flexion in the athletes was higher than that of untrained elderly subjects, especially at a higher speed level (300 deg/sec). There were no significant differences in the femoral CSA measured by magnetic resonance imaging between the eldely athletes and untrained elderly subjects. VOィイD22ィエD2max in the eldely athletes was similar to the values in controls from 50 to 59 years of age. The eldely athletes had higher bone mineral density of the lumber and trochanter major than the untrained men, which corresponded to the values of young sedentary men. The eldely athletes recorded a high score for the fitness test, especially in 10 m obstacle walking, 6 minutes walking and sit up tests.
These results suggest that the elderly elite athletes have excellent physical fitness and that physical training prevents 1) loss of the number of motor unit, 2) decreased VOィイD22ィエD2max, and 3) decline of bone mineral density with aging even in subjects over 80 years of age.
