Aging is a process characterized by morphological (structural) and functional changes that accumulate gradually in the body. These changes affect the performance of the motor skills leading to modifications in psychological and social behaviors. Vibration can be produced by different systems. It can be transmitted to the body of a person producing exercises and it has been proposed as a potential clinical intervention. Aim: To evaluate effects of vibration generated in a special system on physiological and functional parameters in healthy elderly. Methodology: It is an experimental and prospective study of healthy elderly (n=30, aging greater than 60 year old) approved by the Ethics Committee. They were divided in control group (CG) (n=10) who did not undergo intervention, kinesiotherapy group (KIG) (n=10) who performed active exercises and vibration Group (EVMG) (n=10) who underwent exercises produced by vibration generated in a simple system like a "mattress". All the subjects were evaluated (i) before and after each session through Timed Up Test (TUT) (functional capacity) and before and (ii) after each day of intervention with physiological parameters (blood pressure and heart rate). Results: It was observed that there was a significant improvement (p<0.05) of the TUT in the participants of the EVMG and the KIG, and in physiological parameters in the EVMG, a small, but significant alteration in the systolic (increase of 2.4%) and diastolic (decrease of 3.26%) blood pressure and in heart rate (decrease of 2.81%) (p <0.05). Conclusion: In conclusion, the analysis of the results, with elderly participants) indicates that the time to perform the Timed Up Test was shorter in the participants of the kinesioterapy and vibratory groups (vibromanta - a system like a mattress) than of the control group. Moreover, although a significant alteration was found in the participants of the vibratory group in the systolic and diastolic blood pressure and heart rate, these alterations are not too elevated.
