Abstract
The article describes the measuring technique for the passage of mechanical waves through the human axial system (AS) using the vibration analysis. Furthermore, by using the FFT and other mathematical techniques, the human AS rheological characteristics selected are obtained in relation to aging.
The aging process has to be seen in the context of the organism stress history, thus, with regard to the intensity of work, sport or/and health burdens. The lifestyle is thus reflected on the state of the body, organs and tissues themselves.
One of the ways to objectify these changes is to detect the mechanical properties of the pertinent body structures. In the case of the axial system of a person, the assessment of its basic rheological parameters (Young's modulus of elasticity E and viscosity ) is to be dealt with.
The question is whether a trend in human population, according to which the selected mechanical descriptors, depending on the age changes, can be traced, in spite of their unspecified physical stress history. The objective of this case study is based on the use of the methods TVS (Vibration Transfer through Spine) to trace the effects of aging on the mechanical response of the axial system (AS) man.
