Osteoporosis is characterized by low bone mass and micro-architectural deterioration of bone tissue. Postmenopausal women are those at higher risk. The most characteristic condition of osteoporosis is the sudden occurrence of fragility fractures, and the sites predominantly affected are the bones in the wrist, the vertebrae, the hip, the ribs, and the humerus. Osteoporosis can lead to the deformity of the spine, changes in posture, loss of height, chronic pain and disability. Osteoporosis can be caused by multiple factors, the majority of which are hormonal, metabolic, dietary and mechanical, including the lack of exercise and physical activity. Bones respond to pressure in a
similar manner to muscles, by developing hypertrophy as a response to mechanical stimuli resulting in weakening and immobility. Many studies have demonstrated that the combination of strengthening and aerobic forms of exercise are ideal for the retention of healthy bones.
