Brief Summary

This study is a randomized clinical trial that has as objective to evaluate the effects of training with a vibratory platform on body composition, muscular strength functional capacity, flexibility and biochemical profile on elderly women. It will be done in the city of Santa Cruz do Sul, Rio Grande do Sul, with elderly women between the ages of 60 and 80 years-old, within the municipal limits and nearby areas selected randomly by a brown envelope in which a note will be stating if they belong to the control or vibratory platform group, in which the participant will be receiving whole body vibrations on the platform. The recruiting will be done by the institution through e-mail or by public call. Women will be evaluated through anamesis. On the evaluation, a questionaire will be applied, in order to evaluate if they don´t have counterindications for the vibratory platform. They will be evaluated in their general health, socio-economical status, and history of physical activity. Participants will have their doubts cleared about the study, and a written consent will be signed. Before the intervention with whole body vibrations, nutritional and physical activity aspects will be evaluated. The treatment period on the vibratory platform will be of 8 weeks, before and after it, anthropometrical, biochemical, strength, flexibility, palmar prehension strength, metabolic basal load, and functional capacity measurements will be taken. Before and after every session on the vibratory platform, heart rate, respiratory rate, arterial pressure, and peripheric oxygen saturation will be evaluated. The interventional procedure will be done with a vibratory platform (Power Plate®, model my7™, UK) with a frequency of 30 - 40 Hz, with low (2mm) or high (4mm) amplitude. Training will last 8 weeks with 3 sessions per week, lasting between 30 seconds and 1 minute of training, and 30 seconds to 1 minute of rest, with the subject positioned in orthosis with a knee flexion of 15° and a feet width distance of 20 cm. The frequency will be of 35 Hz and the amplitude of 2 mm. The study aims to contribute with reducing the body mass index and body fat percentage, to improve the lean mass, palmar prehension strength, muscular strength on the lower limbs and flexibility, also obtaining better biochemical profiles after the training period.

Outcome Measures

Primary Outcomes (3)

• Effects of whole body vibrations training on Functional Capacity in Elderly Women.

  Functional Capacity will be measured through distance traveled with the six minute walk test.

  eight weeks

• Effects of whole body vibrations training on Muscle Strength in Elderly Women.

  Muscular strength will be measured by the maximum repetitions test.

  eight weeks

• Effects of whole body vibrations training on Biochemical Profile in Elderly Women.

  Biochemical profile will be measured through blood collection and there will be a result (number) for each one of the following variables: hemogram, glycemia, cholesterol, triglycerides, Urea, creatine, uric acid. Oxidative stress will be measured through TBARS test, which will present a numerical result.
