[Osteoporosis is prevented by physical activity, calcium and hormone supplementation].

As the incidence of osteoporosis-related fractures is increasing and constitutes a major health problem in the Western world, their prevention is of great importance. Physical activity, combined with adequate calcium intake and hormone levels, is necessary for the formation and maintenance of bone tissue. The effects of physical exercise on bone tissue variables are most beneficial when it is intensive, regular, and of weight-bearing character. Physical exercise may also be of value in the future treatment of osteoporosis. In addition to its skeletal effects, such exercise improves physical fitness, muscle strength and co-ordination, resulting in a reduced risk of fractures and improved quality of life.
