Introduction: Osteoporosis and Osteopenia are common bone disorders, characterized by low bone mass, signs of bone deterioration and are responsible for typical bone fragility. Physical activity is certainly a valid prevention tool because it contributes to a healthy energy balance, increasing muscle mass and providing beneficial effects in bone metabolism. Stress induced by more vigorous activities such as weight lifting, increases the risk of injury, particularly in the elderly. Therefore, alternative strategies with lower risk of injury are indicated such as whole body vibration and walk.

Objective: Compare the effect whole body vibration and walking on muscular strength, balance and functional performance in the elderly with Osteoporosis and Osteopenia

Methods: It is a clinical trial study, controlled, parallel, randomized and blind, which will follow the guidelines established in the Consolidated Standards of Reporting Trials (CONSORT). Participants will be randomly distributed in 2 groups: the experimental group (GI) that will hold the training in the vibrating platform and the control group (GC) that will perform the walk, settling 1 treatment session. All participants will be subjected to the initial and final assessment.

Inclusion Criteria:

• Confirmed diagnosis of osteoporosis or osteopenia examination of bone densitometry;
• Patients without severe neurological disease, vascular disorders, labyrinthitis and blindness;
• No use of gait auxiliaries;
• No history of fractures of the lower limbs in the last year;
• Do not be an alcoholic inactive (0 to 5 points) or less active (6 to 11 points) accordance with the usual physical activity questionnaire (QAFH).

Exclusion Criteria:

-Patients who submit to hypertensive peak, nausea and dizziness during the training program.

Triple: a researcher shall be exclusively responsible for the evaluations and reevaluations not having knowledge of what intervention group the patient will enter. The patient will be allocated among three groups. After the final evaluations, all data will be analyzed by another researcher directed solely to that purpose. Therefore, there will be a triple blinding (researcher, patient and statistician).
