[Physical activity of the elderly - what kind of and what for?].

Starting to exercise is beneficial even at an older age. Versatile exercise improving the condition of the respiratory and circulatory system, muscle strength and mobility is effective for maintaining functional capacity, especially among those having an already impaired mobility and functional capacity. Physical exercise can slow down the progress of bone loss, and intense exercise may even serve to increase the bone density in an elderly person. The main focus of physical activity aiming at the prevention of failings and fractures is in training that improves balance and muscular strength in the lower extremities. Endurance exercise and strength training seem to diminish the impairment of cognitive functions.
