RESUMO:

Background: Elderly people tend to present a decrease of the trophism, amplitude of muscular activation and strength, which causes significant negative implications in their functionality. Studies about exercise on vibratory platform have been performed, however, there is a lack in the literature regarding the possible neurophysiological acute effects of this technique in elderly people. Objective: To analyze the immediate effects of an exercise session on the vibratory platform on the lower limb neuromuscular performance in elderly. Methods: This is a ramdomized, blind, controlled trial, where 44 volunteers, from both genders, mean age of 68,5 ± 2,67 years, were submitted to an evaluation of the postural oscillation (baropodometry), isocinetic performance and electromyographic activity of the vastus lateralis and soleus muscle of the dominant limb. After, they were randomly assigned to two groups, with 22 participants each: placebo group - underwent a series of exercises with the vibrating platform off; and experimental group - underwent a series of exercises with the vibrating platform on, configured at frequency of 40 Hz and a displacement amplitude of 4 mm. Both groups executed the same exercise protocol in the platform, composed of a bipodal isometric squat at 40⁰ of knee flexion, being 4 series of 90 seconds of duration, with interval of 1 minute. At the end of the intervention, the volunteers were submitted to a re-evaluation identical to the previous one, performed before the exercise protocol. Data were analyzed using SPSS 21.0 software, assigning a level of significance of 5% (p ≤ 0,05). To the analysis of normality of data it was used the Kolmogorov-Smirnov test and to attest the homogeneity between groups, a paired-sample test t. To compare the differences within and between group, it was used a mixed model ANOVA. Results: There was a significant between-group increase in RMS for the VL and within group in the soleus RMS after the intervention protocol in the GE. In the evaluation of the isokinetic performance, the torque peak of the knee extensors showed within group increase for GE and in the plantar flexors, an increase in within group was observed for the GP and GE; for the power variable there was an within group increase in both groups. There was no significant differences in postural oscillation. Conclusions: The protocol of exercise in the whole-body vibration produced a greater neuromuscular recruitment of the VL and soleus muscles in the elderly adults. However, immediately, there were no changes in postural oscillation or in isokinetic performance of these subjects, except for the peak torque of the knee extensor group.
