[Role of physical activity for the prevention and rehabilitation of osteoporosis].

The therapeutic exercises pursue preventive as well as rehabilitative aims within the osteoporosis therapy. The objective depends on whether an osteoporosis already occurred and it depends also on the respective stage of the osteoporosis. Aims and main points from the physiotherapy and sports therapy are: construction of the bone substance; receipt of the bone substance; pain alleviation; fall prophylaxis. To reach an optimal bone mineral content in recent years activities are necessary on which own body weight must be carried. In the later adult age the same activities in addition are necessary to reduce the natural reduction rate of bone mineral content to a minimum. With beginning or already occurred osteoporosis must those activities be operated with caution and restraint which have to do with abrupt interceptions of the body weight.The combination of medication and physical activities shows better therapy results as the respective measures alone. An important therapeutic aspect with older humans exists in the reduction of the fall risk and thus the fracture risk. In addition a muscle training - as for example in the medical training therapy - can raise the pain threshold, so that the pain sensitivity of the patients is improved.
