Aging, Healthy
Conditions
Brief summary
Aging causes anatomical and physiological changes in the cardiovascular system and autonomic function with decline in its maximum function. This study aimed to evaluate the acute effects of whole body vibration on cardiovascular system, autonomic function and heart variability in healthy young and elderly. The investigators' hypothesis is that whole body vibration has different effects in young and elderly.
Interventions
OTHERWhole Body Vibration
A whole body vibration session will be performed through a vibrating platform with three axes and vibration frequency set at 35 Hz. The amplitude used will be 04 mm.
