The purpose of this study is to analyze the immediate effects of an exercise protocol on the vibration platform on the functional and neuromuscular performance of lower limbs, postural control and life quality in healthy elderly.
The research is a randomized controlled trial that will be developed at the Laboratório de Análise da Performance Muscular (LAPERN) of the Physiotherapy Department of the Federal University of Rio Grande do Norte (UFRN). The population of the present study will be formed by elderly individuals living in the city of Natal / RN, aged between 65 and 75 years, of both sexes, without distinction of race, education and marital status. The research sample will be of a non-probabilistic type, in which these will be allocated randomly into two distinct groups: placebo group (GP) and experimental group (GE). This research was submitted to the Research Ethics Committee (CEP) for UFRN through the national interface Plataforma Brasil. The present research contemplates the ethical aspects based on Resolution 466/2012 of the National Health Council (CNS) and the Declaration of Helsinki for research with humans. In addition, the survey will be recorded in Clinicals Trial. All data will be recorded in a database of the laboratory under confidentiality and can only be handled by the responsible researchers. The study will only begin after the issuance of the referent opinion approving the project. All subjects will be duly informed and instructed regarding the scheduled procedures, which will only be executed after reading, accepting and signing the Term of Free and Informed Consent (TFIC). After approval by the Research Ethics Committee, following resolution 466/2012, a pilot study was carried out aiming at the adequacy of all the research procedures, as well as the training of the researchers involved. Initially the research will begin with the selection of the sample according to the inclusion criteria descried elsewhere. The evaluation will be scheduled by telephone contact. Following this, the volunteers will receive the TFIC for reading and due signature. The data collection process will take place in four stages: (1) initial evaluation, (2) sample allocation (3) application of exercise program and (4)reevaluation. The evaluations will be composed by the dynamometric analysis associated with EMG (electromyography) and postural control analysis. The volunteers will be allocated randomly into 2 groups: placebo group (with the platform off) or experimental group (with the platform set at a frequency of 40 Hz and amplitude of 4 mm). Both will perform a bout of exercise in the vibrating platform, consisting of a static bipodal squat at 40 ° of knee flexion, with 4 sets of 1.5 min, with a rest interval of 1 minute. Immediately after the exercise the volunteers will be submitted to a revaluation, with the same procedures of the initial evaluation.

Exclusion Criteria:
Subjects will perform an isometric semi-squat exercise associated with the vibratory platform. The exercise will consist of 4 series of an isometric half-squat exercise with 1 minute and a half of duration and a rest interval of 1 minute. The vibratory platform will be connected at the beginning of each series, set at a vibration frequency of 40 Hertz (Hz) and peak-to-peak amplitude of 4 millimeters (mm) resulting in a peak acceleration of 128 ms2 (12.8 g). This should provide the equivalent of 3600 vertical vibrations, totaling 14400 vibrations per training session
Other: WBV exercise group
Subjects will perform an isometric semi-squat exercise associated with the vibratory platform. The exercise will consist of 4 series of an isometric half-squat exercise with 1 minute and a half of duration and a rest interval of 1 minute. The vibratory platform will remain off at all sessions. A device will be attached to the side of the platform in order to produce a sound, similar to the sound produced by the vibrating platform when it is in operation.
Other: Sham WBV exercise group
The intervention will consist of a half-squat isometric whole-body vibration exercise with the platform configured at a frequency of 40 Hz and peak-to-peak amplitude of 4 mm. The sessions will be held 2 times a week, consisting of 4 sets of 1 and a half minutes of exercise on the platform. Rest intervals of 1 minute between sets will be respected.
The intervention will consist of as half-squat isometric exercise , but the platform will remain off at all sessions. A device will be attached to the side of the platform in order to produce a sound, similar to the sound produced by the vibrating platform when it is in operation.

Ran from Mar 2018 to primary completion in Apr 2018, 1 month.
Of 5,147 non-industry interventional studies with no phase under Motor Activity, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 36. This study's 1 month is below that.
Counting every sponsor, half of 5,207 studies reached it within 17 months; a quarter within 7 and three quarters within 36.
