Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected to find greater muscle activation and greater acceleration when exercise is associated with whole body vibration, being greater at lower vibration frequencies. For that, the acceleration will be evaluated by the accelerometer instrument and the muscular activity measured by the portable electromyograph. To verify the outcome, the peak frequency and root mean square (RMS) of both instruments will be evaluated, based on the observation of a variation of at least 5% in the comparisons between the experimental situations. | — |
