Brief Summary

Women in the postmenopausal period suffer hormonal changes that contribute to a number of negative factors to health, such as reduced bone mineral density and loss of muscle mass, which contribute to the increased incidence of falls and consequent risk of fractures. Among the possibilities to alleviate these symptoms are mainly drug treatment and the systematic practice of physical exercise. Exercise stands out for not offering adverse effects. One form of exercise that has been recently investigated is the whole body vibration, another form of exercise well accepted by the population is the Pilates method. Taking into account the lack of literature on the benefits of vibration training; and also the Pilates method on bone mineral density, muscle strength, flexibility, postural balance, fear of falling and the quality of life of postmenopausal women, explains the importance of this work.

Outcome Measures

Primary Outcomes (1)

• Bone mineral density

  To analyze the bone mass of the femoral neck and lumbar spine (L1-L4) will use the device-ray Absorptiometry Dual Energy X (DXA) HOLOGIC, DQR-1000 PLUS model. The technique is based on the attenuation by the patient's body, a radiation beam generated by an X-ray source with two power levels, and exposure to radiation is lower than that of a conventional X-ray examination. The technique allows to estimate bone mass in whole and body segment. The results are transmitted to the computer that is connected to the device. Bone mineral density (BMD) is expressed as absolute values (g / cm2 grams of bone mineral content per area or analyzed bone cm2).

Study Arms (3)

Whole-Body Vibration Group (WBV)

EXPERIMENTAL

Will be exposed to five minutes on a vibrating platform (Oscillating Platform Semi-Professional Horizontal - Arktus, Cascavel, Brazil), this type of platform vibrates through an anteroposterior axis, causing the right and left sides alternate horizontally denominated: alternating side vibration platforms, will be performed three times per week on alternate days (5 minutes). a frequency of 20 Hz (1 = 1 Hz oscillation / second) and a magnitude of 3.2 g (1 g = 9,81 m / s gravity) is used. The volunteers will be guided to stand on the platform with semi-flexed knees, barefoot and apart about hip width.

Other: Whole-Body Vibration

Pilates Group (PG)

EXPERIMENTAL

Will be exposed to 60 minutes, held three times a week on alternate days. Pilates equipment used for the exercises are: Combo Chair, Cadillac Trapeze, Ladder Barrel, Reformer Universal, Step Barrel and Wall Unit. Will be selected for this study, 21 strengthening exercises and stretching to the main body segments. All exercises are performed in a series of ten repetitions with one minute interval between exercises. To determine the level of effort and consequently to changing loads, will be used verbal command according to the Borg CR10 scale. The level of effort will be maintained during the session heavy (Borg between 5 and 6).

Other: Pilates

Control Group (CG)

NO INTERVENTION

The control group will be instructed to maintain their usual activities both in relation to their daily activities, dietary habits, failure to use drugs that can influence the increase in bone mass and participate in monthly meetings to address on issues osteoporosis and postmenopausal women. After the end of the interventions with WBV and GP groups, GC volunteers will be invited to also perform whole body vibration for six months. Exposure of vibration will be for five minutes on a vibrating platform, three times per week on alternate days. a frequency of 20 Hz (1 = 1 Hz oscillation / second) and a magnitude of 3.2 g (1 g = 9,81 m / s gravity) is used. Likewise which was offered for the WBV group.
