[Aging and physical activity]

Advancing age is accompanied by changes in the cardiovascular system with a rapid reduction of, among other things, cardiac output, respiratory capacity, and maximum oxygen absorption capacity. Changes in articular cartilage, muscles, and intervertebral ligaments are the cause for many degenerative diseases of old age and considerably restrict physical performance capacity in later years. Nevertheless, there is increasing evidence that a high level of activity during old age and thus an influence on the aging process can be achieved by constant training begun as early as young adulthood. This type of training must concentrate on improving muscle strength, general flexibility, and endurance. Thus, it is our task to perceive physical activity as a medical prescription for the aging population.
